Authors:

Abstract and Figures

BACKGROUND: Tissue compression and partial vascular occlusion using band flossing results in reperfusion of blood to the muscle tissue that may ultimately reduce joint pain and increase range of motion, enhancing prevention from or rehabilitation of injury. However, the extent of research examining the effect of tissue flossing in an athletic setting is currently very limited, and the effects of band flossing on knee pain and jump performance have not yet been investigated and remain unclear. PURPOSE: To investigate the effect of band flossing on perceived knee pain and vertical jump performance in recreational athletes with knee pain. METHODS: Five young male recreational athletes with previously reported knee pain took part in this study (age 22±0.5; height 184±6.8cm; weight 79±1.5kg; BMI 23.34±1.2 kg/m2). Participants performed a number of tests pre and post intervention, with the application of a floss band on the knee joint. The experimental protocol consisted in the performance of countermovement jump (CMJ) tests (without occlusion, with occlusion, and after occlusion). Pre and Post intervention measures included a perceived knee pain -by visual analogue scale (VAS)- and CMJ performance -by force platform-. RESULTS: The application of flossing bands in knee joint resulted in enhancements in all test measures pre to post intervention (10% jump height; 4.5% time in the air; 5% jump velocity; 13% jump power; 7.5% jump force). Participants reported a 3.5-point pain enhancement in AVS during performance of CMJ tests. CONCLUSION: Flossing bands caused a reduction in perceived knee pain and improved vertical jump performance in young male recreational athletes.

1. Introduction
In recent years, the use of compressive materials has
grown considerably, both for the improvement of physical
performance and for health. This boom is due, to a greater
extent, to the benefits provided by their use. For its correct
application, different types of garments and/or
compressive materials have been developed that respond to
different areas and objectives.
One of the most widespread compressive materials are
compressive garments. Their origin comes from the health
field and it has been demonstrated that they have positive
effects on the blood circulation of the extremities [1,2]. In
the field of sports, it has been proven that the prolonged use
of compressive garments has improved performance in
different sports [35]. The possible explanation would be
its positive effects on venous hemodynamics [6], decreased
exercise-induced muscle damage [79], and its possible
contribution to recovery [8,1012]. There are different
types of compression garments, stockings, sleeves, upper
body garments (covering the torso and upper limbs
completely or partially) and lower body garments (from the
waist, covering the lower limbs completely or partially)
[13].
Another compressive material whose use has grown
exponentially in recent years in the field of strength
training, are occlusion cuffs. Unlike garments, these apply
a band (inflated, elastic or rigid) to the area closest to the
extremities with the intention of restricting the blood flow.
Strength training with blood flow restriction (BFR) has
shown significant gains in hypertrophy [1416] and muscle
strength [15,1719]. In addition, these benefits are
obtained by training at low intensity (loads around 20-40%
of 1RM). It is therefore a very useful method for sectors of
the population that, for health reasons, do not tolerate high
loads on their joints and must improve their strength and
hypertrophy [17,2022].
On the other hand, recently a new material and method
has been incorporated to compress the joints by means of
an elastic band called flossing or floss band [23]. This
consists of the use of reusable rubber bands with the aim of
compressing a muscle region or a joint. Its purpose is to
64 The Effects of Tissue Flossing on Perceived Knee Pain and Jump Performance: A Pilot Study
improve the range of motion (ROM), restore the mechanics
of the joints and decompose the adhesive tissue of the
previously injured musculature.
There is scientific evidence that supports its use to
increase ROM [2426] and pain reduction [24,27].
However, these results are not conclusive as there are other
studies in which no improvement has been observed in
these two variables [28,29]. Most studies have applied the
flossing band to the ankle [25,26,30,31], the shoulder [29],
or the wrist [24]. Only in one case has it been applied to the
knee and improvements in strength were observed [32].
Concurrently, one of the most common knee problems is
patellofemoral pain syndrome (PFPS), which is
characterized by the presence of peripatellar or anterior
knee pain [33], affecting one in four people [34,35], and
also being responsible for a high percentage of knee sports
injuries [36]. For that reason, it would be helpful to find a
non-invasive way to improve this issue.
The effects of the flossing band on ROM, performance
and knee pain are unknown, but since improvements have
been seen in other joints [24,27], and other therapies
similar to flossing band, such as bandaging techniques
(Infrapatellar, Kinesiotape or McConnell), have been
shown to help reduce painful symptoms and improve
muscle function and strength [37–41], flossing band could
probably also be applicable to the knee joint.
Therefore, the objective of this work is to investigate the
effect of elastic bands (flossing) on perceived knee pain
and vertical jump performance in amateur athletes with
PFPS.
2. Materials and Methods
2.1. Participants
Five young male recreational athletes with PFPS took
part in this study (age= 22.0±0.5 years; height= 184.1±6.8
cm; weight= 79.0±1.5 kg; BMI= 23.34±1.20 kg/m2). To
be eligible for this study, they all had to have been
diagnosed with the PFPS for at least three months, but no
known knee injury. They all had strength training
experience and signed an informed consent form prior to
any intervention or data collection. Candidates who could
be adversely affected (cardiovascular or joint health) by
the intervention in the study were excluded.
2.2. Procedure
The participants performed a pre and post test, with or
without application of a floss band (Life Floss bands,
Sydney, Australia) on the painful knee. Two different days
(intervention and control) were used to carry out the
protocol, using the application of the floss band in the first
of them, and eliminating its use in the second. The aim of
the separation into two days was to rule out that the
application of one protocol would affect the results of the
next.
On the first day (FLOSS) three series of three counter
movement jumps (CMJ) were performed, with the average
of the three jumps in each series. CMJ was performed from
an upright position with straight legs, beginning the jump
with a counter movement down to a knee angle of 90
degrees. Hands were held on the waist during the whole
jump to avoid any effect of arm-swing. We used 1-minute
rest between series, and 15 seconds between repetitions. 1st
series: without application of floss band (PRE); 2nd series:
with application of floss band (FB) (Figure 1); 3rd series:
without application of floss band, after removal (POST).
On the second day (CON), the same protocol was
performed, but without the application of floss band: three
series (S1, S2 and S3) of three CMJ with 1-minute rest
between series and 15 seconds between repetitions. The
same jump performance and perceived pain variables were
measured on both days.
Figure 1. CMJ with floss band
2.2.1. CMJ
Each participant performed the CMJs with their hands
on their waist, starting from an upright position and
keeping their legs extended throughout the flight phase.
Variable jump height, time in the air, jump velocity, jump
power and applied force were measured using a force
platform (Kistler 9287 BA, Kistler Instruments Ltd., Hook,
UK).
Perceived knee pain was also measured in all three
phases of the protocol. Each phase corresponds to the
perceived pain at the end of each series of three CMJs. A
visual analogue scale (VAS) divided into 10 equal parts
(indicating 0 as no pain and 10 as unbearable pain) was
used for assessment.

2.2.2. Floss Band Application
The painful knee was bandaged according to the
manufacturer, surrounding it from the most proximal to
the most distal area, leaving 30% of the band visible and
overlapping along the joint (Figure 2). To ensure that the
pressure of the band was adequate, the Kikuhime pressure
measuring sensor (MediGroup, Melbourne, Australia),
located between the band and the lateral condyle of the
femur, was used. The average pressure was 182±38
mmHg.

2.3. Statistical Analysis
Data analysis was performed using the IBM SPSS
Social Science Statistical Package, version 25.0 (SPSS
Inc., Chicago, IL, USA). The sample distribution was
tested using the Shapiro-Wilk test. A T-Student test was
performed to check if there were significant differences. A
value of p<0.05 was established to determine statistical
significance.
3. Results
Significant differences were found in all the analysed
variables regarding the performance of the vertical jump in
the protocol applying the floss bands (p<0.05). No
significant differences were found in any of the variables
analysed related to the vertical jump performance in the
protocol that did not apply the floss bands (p=0.283).
Significant differences in perceived pain were found in the
protocol applying the floss bands (p<0.001). No significant
difference in perceived pain was found in the protocol that
did not apply floss bands (p=0.413). Table 1 presents these
results.
All variables were evaluated during the three series of
jumps, although significant differences were only found
between the first and third series. Thus, the application of
the floss bands was found to significantly improve the
performance of the CMJ, as well as significantly reduce the
perception of pain in the knee where the floss bands were
applied, but not during their application, but after their
removal.

66 The Effects of Tissue Flossing on Perceived Knee Pain and Jump Performance: A Pilot Study
4. Discussion
The aim of this work was to identify whether the
application of the floss band to the knee joint could
increase the performance of the CMJ and decrease the
sensation of pain in this joint.
Different studies have shown the benefits of floss bands,
although the vast majority have used them on joints other
than the knee. Stevenson et al. [25] showed that, by
compressing the ankle joint for 2 minutes, significant
improvements were achieved in dorsiflexion of this joint
(p<0.032). Driller & Overmayer [26], also found
significant improvements in ankle ROM and one-leg
jumping performance (p<0.01). The same research group
in a later work found, in agreement with the previous one,
that the application of the floss bands in both ankles during
2 minutes, could improve the performance in the ROM, the
CMJ and the sprint until 45 minutes after its application
[30]. However, although significant differences were found
in ankle ROM (p<0.05), both CMJ and sprint performance
were not (p>0.05). Very similar results were obtained by
Mills et al. [31], finding improvements in ankle ROM,
CMJ and sprint performance, although not significant in
the latter two (p<0.05).
Floss bands have also been applied to other joints, such
as the shoulder, in order to analyse their influence on ROM
and their power in the bench press movement [29].
Although no significant differences were found in any of
these variables, the authors suggest that floss bands may
have a greater influence on less complex joints than the
shoulder. They attribute this lack of efficacy to the
deficiency of the bandage to compress all the muscles
involved in the movements evaluated. On the other hand,
the wrist has also been analysed, in a case study based on a
participant with "Kienböck disease" (aseptic avascular
necrosis of the crescent carpal), who presented pain and
swelling on the right wrist dorsum [24]. In this work, the
influence of the floss band on pain reduction and
improvement of wrist functionality in aspects of daily life,
such as pain, numbness, tingling, ability to drive or work,
was analysed by means of questionnaires. After 6 weeks of
application of the floss band treatment (1-3 minutes of
application before your rehabilitation exercises),
significant improvements in both pain perception and wrist
functionality were found (p<0.05).
Although the use of the floss band is recent, different
modes of compression or bandaging have shown benefits
for decades. Patellar taping, for example, showed a
significant decrease in pain (p<0.005) and an increase in
performance in the Star Excursion Balance Test in patients
with PFPS [39]. Kuru et al. [41] concluded that Kinesio
bands showed the same benefits as electrostimulation in
patients with PFPS, in terms of pain reduction, improved
ROM, strength, functional capacity and quality of life. It is
relevant to mention that both works, contrary to our results,
showed the benefits during the application of the band,
while in the present work the improvements came after
removing the floss band.
Mason et al. [37], on the other hand, also found benefits
in pain reduction in patients with PFPS by means of
infrapatellar taping, being applied continuously throughout
the week. However, their results concluded that greater
benefits are obtained when combined with quadriceps
stretching and strengthening work. Similar results were
evidenced by Paoloni et al. [40], where they suggested that
a short period (14 days) of patellar taping and a subsequent
exercise program was a good means of controlling
long-term pain in participants with PFPS associated with
muscle dysfunction.
Although it is complicated to allude to the
physiological or mechanical mechanisms that could have
favoured the changes described, it seems that our results
are in the same direction as other previous work that has
used this type of implement or some similar ones.
Therefore, it is suggested that future research will be able
to identify what these mechanisms are, as well as to
provide more evidence and clarity to joint compression by
means of floss bands.
5. Practical Applications
Other studies have shown the importance of good ankle
dorsiflexion in shock absorption in the lower extremities
when landing a jump [42], thus justifying the use, prior to
exercise, of floss bands on the ankle [30]. Therefore, the
previous results, as well as those obtained in this study
suggest that there could be powerful and useful practical
applications, considering the use of floss bands during the
warm-up prior to training, or even competition. This
would be a good method to reduce pain produced by
PFPS, as well as to increase performance in vertical
jumping. Any sport or physical activity in which vertical
jumping is a performance factor could benefit greatly
from this type of technique, although future research
should establish which protocol produces the greatest
gains in these variables.
6. Conclusions
The present study adds useful and interesting
information to the novel field of floss bands, in relation to
the reduction of knee pain in participants with PFPS and
the increase in CMJ performance. Both variables have
been improved after the application of these bands and
their subsequent removal. These preliminary results can
have a relevant impact in the sports setting, both
recreational and competitive.

... Tissue flossing has been used to prevent sports injuries and improve sports performance [17]. Floss bands (FLOSS) are a novel tool used to improve joint ROM [18,19] or reduce pain [20]. They can be applied before or after sports for injury prevention or rehabilitation. ...
... Studies have yet to thoroughly explore whether a combination of tissue flossing and functional exercises for the knee joint can improve sports performance. Marco et al. investigated the effect of tissue flossing on perceived knee pain and vertical jump performance in five young male recreational athletes with knee pain [20]. Significant differences in vertical jump performance and perceived pain were identified between the tissue flossing protocol and the nonflossing protocol. ...
... Few studies have investigated tissue flossing over the knee, and no study has analyzed differences between men and women. In García-Luna's study, five young male recreational athletes with previously reported knee pain due to patellofemoral pain syndrome performed countermovement jumps with and without FLOSS wrapping over the knee on two separate days [20]. The study concluded that flossing can reduce perceived knee pain and improved vertical jump performance in young male recreational athletes. ...

Flexibility, specifically that in the amplitude of sagittal-plane range of motion (ROM), can improve jump landing patterns and reduce the potential for sports injury. The use of floss bands (FLOSS) reportedly increases joint range of motion (ROM) in the shoulder, ankle, and elbow joints. However, little research on the effectiveness of FLOSS on the knee joint has been conducted. This study investigated the effects of FLOSS on knee ROM, static balance, single-leg-hop distance, and landing stabilization performance in women. This study had a crossover design. Twenty active female college students without musculoskeletal disorders were randomly assigned to receive a FLOSS intervention or elastic bandage (ELA) control on their dominant knees. The participants underwent FLOSS and ELA activities on two occasions with 48 h of rest between both sets of activities. The outcomes were flexibility of the quadriceps and hamstrings, how long one could maintain a single-leg stance (with and without eyes closed), distance on a single-leg triple hop, and score on the Landing Error Scoring System (LESS); these outcomes were evaluated at preintervention and postintervention (immediately following band removal and 20 min later). After the FLOSS intervention , the participants' hamstring flexibility improved significantly (immediately after: p = 0.001; 20 min later: p = 0.002), but their quadricep flexibility did not. In addition, FLOSS use did not result in worse single-leg stance timing, single-leg triple-hop distance, or landing stabilization performance relative to ELA use. Compared with the ELA control, the FLOSS intervention yielded significantly better LESS at 20 min postintervention (p = 0.032), suggesting that tissue flossing can improve landing stability. In conclusion, the application of FLOSS to the knee improves hamstring flexibility without impeding static balance, and improves single-leg hop distance and landing stabilization performance in women for up to 20 min. Our findings elucidate the effects of tissue flossing on the knee joint and may serve as a reference for physiotherapists or athletic professionals in athletic practice settings.
... Over the past few years, flossband application has been more commonly used in the field of training or rehabilitation. Accordingly, researchers have concentrated on testing the effects of flossband application on joint ROM in different joints [7,8], muscle tightness [9,10], muscle strength [15,16], as well as physical function performance [8,[11][12][13]. However, despite the apparent benefits found in the above parameters, there was no relevant literature review that integrated these different findings. ...
... Only 1 out of 23 studies investigated the effectiveness of the application of flossband on chronic pain management. In Garcí a-Luna"s [7] pilot study, five young male recreational athletes diagnosed with chronic patellarfemoral pain syndrome (PFPS) were recruited, and all the participants were instructed to do three counter movement jumps (CMJs) with a flossband wrapping above the patellar (with 182±38 mmHg), or without it, during pre-and post-tests for evaluation of the acute effect of variation of knee pain intensity. The results showed that the application of flossband on patients with chronic PFPS was found to significantly decrease the perception of knee pain (Analogue visual scale, VAS) after immediately removing the flossband [7]. ...

Flossband, as a novel and effective tissue flossing technique, is becoming increasingly popular in the field of athletic training, sports injury prevention, and rehabilitation. The purpose of this literature review is to summarize updated evidence about the effects of flossband application on joint range of motion (ROM), pain, muscle tightness, strength, and physical functional performance as well as identify research gaps for future study. Google Scholar, PubMed, EBSCO, and Web of Science were used to search related articles. The keywords of floss bands, flossbands, floss band, tissue flossing, flossing band, voodoo floss band, voodoo floss bands, track floss, rock floss, life floss band, and Rogue voodoo floss were used to extract target articles. English journal articles, full-text available, and content related to outcome measures were included. Conference abstracts, books, case studies, guideline reviews were omitted. 23 full-text journal articles were included for further qualitative analysis after removing duplicates and deleting articles that violate the screening criterion. Flossband application on limbs, soft tissue, or joints with about 50% flossing tension or 150 mmHg wrapping pressure could have small to medium effects on the parameters of ROM, muscle stiffness, muscle strength, and physical function performance, and large effects on pain management. Most previous studies were mainly focused on the acute effect of flossband application on peripheral joints or soft tissues in healthy and active participants or well-trained athletes. Therefore, for future studies, more evidence is needed on the benefits of long-term flossband trunk application and concerning patients with various diseases.
... One explanation for the conflicting results of the published literature could be the difference in methodology used. For example, Driller and Overmayer (2017) applied the floss band around the ankle joint, whereas García-Luna Marco et al. (2020) wrapped the floss band around the knee joint, providing minimal coverage of the soft tissues. Other authors, however, applied floss band around thigh (Vogrin et al., 2020a;Konrad et al., 2020), thus covering only the soft tissue, which may have different effects on local tissue perfusion and corresponding neuromuscular function. ...

Nowadays, various methods are used for acute performance enhancement. The most recent of these is tissue flossing, which is becoming increasingly popular for both performance enhancement and rehabilitation. However, the effects of flossing on athletic performance have not been clearly demonstrated, which could be due to differences in the methodology used. In particular, the rest periods between the end of the preconditioning activity and the performance of the criterion task or assessment tools varied considerably in the published literature. Therefore, the present study aimed to investigate the effects of applying tissue flossing to the thigh on bilateral countermovement jump performance and contractile properties of vastus lateralis (VL) muscle. Nineteen recreational athletes (11 males; aged 23.1 ± 2.7 years) were randomly assigned to days of flossing application (3 sets for 2 min of flossing with 2 min rest between sets) with preset experimental pressure (EXP = 95 ± 17.4 mmHg) or control condition (CON = 18.9 ± 3.5 mmHg). The first part of the measurements was performed before and after warm-up consisting of 5 minutes of cycling followed by dynamic stretching and specific jumping exercises, while the second part consisted of six measurement points after flossing application (0.5min, 3min, 6min, 9min, 12min, 15min). The warm-up improved muscle response time (VL=-5%), contraction time (VL=-3.6%) muscle stiffness (VL=17.5%), contraction velocity (VL=23.5%), jump height (13.9%) and average power (10.5%). On the contrary, sustain time, half-relaxation time and take-off velocity stayed unaltered. Flossing, however, showed negative effects for muscle response time (F=18.547, p < 0.001), contraction time (F=14.899, p<0.001), muscle stiffness (F=8.365, p < 0.001), contraction velocity (F=11.180, p < 0.001), jump height (F=14.888, p < 0.001) and average power (F=13.488, p < 0.001), whereas sustain time, half-relaxation time and take-off velocity were unaffected until the end of the study protocol regardless of condition assigned and/or time points of assessment. It was found that the warm-up routine potentiated neuromuscular function, whereas the flossing protocol used in the current study resulted in fatigue rather than potentiation. Therefore, future studies aimed to investigate the dose-response relationship of different configurations of preconditioning activities on neuromuscular function are warranted.
... It is a big problem for the athletes' future performance. Research has found that a person's body balance is affected by fatigue [8]. ...
... Another primary concern about the effects of fatigue on balance is in the athletic population. So far, researchers can only estimate that athletes need rest for 8-20 minutes before testing balance [8][9][10]. It can be a big difference depending on the situation. ...
... While plantar flexor isometric strength (Galis and Cooper, 2020;Kaneda et al., 2020a) and balance (Pakarklis and Šiupšinskas, 2018) seem to be unchanged following calf flossing, RFD in various time frames (e.g., 0-50 ms) showed an increase ranging from 5.10 to 21.10% (Kaneda et al., 2020a). Knee flossing was only applied in one study (five measures) with all parameters (related to jumping) significantly improved when comparing before and after values (Marco et al., 2020). Thigh flossing was performed in three studies with a total of 13 measures. ...
... No significant change in pain of the shoulder was reported, though it is possible that the study was underpowered to detect clinically relevant changes. Furthermore, a pilot study (Marco et al., 2020) with five young male athletes who suffered from knee pain reported significant improvements in both pain (visual analog scale) and jump performance following a single floss band treatment on the knee joint. ...

There is a belief that tissue flossing can improve range of motion or performance, speed up recovery, and decrease pain caused by various diseases or injuries. As a result, many therapists, patients, and athletes are now using this technique. Consequently, in the last five years, a number of studies have addressed these assumptions. The purpose of this scoping review is to introduce the application of a floss band and to summarize the existing evidence for the effect of floss band treatment on range of motion, performance, recovery, and pain (due to disease or injuries). A further goal is to suggest what needs to be addressed in future studies. The online search was performed in the PubMed, Scopus, and Web of Science databases. Any studies dealing with the effects of a floss band treatment on range of motion, performance, recovery, or pain parameters in any population (e.g. patients, athletes) were included in this review. Twenty-four studies met the inclusion criteria, with a total of 513 participants. The included studies revealed that there is evidence that a single floss band treatment is able to increase the range of motion of the related joint and can positively affect jumping and strength performance. However, these findings show only small to moderate effect sizes. Although not yet clearly understood, a possible mechanism for such changes in range of motion or performance is likely due to changed neuromuscular function, rather than changed mechanical properties of the muscle (e.g. stiffness). All in all, there is a need to conduct long-term studies about the effects of flossing treatment on range of motion and performance (e.g. strength or jumping parameters) and its related mechanism (e.g. pain tolerance). There is weak evidence that flossing can be of value for pain relief in the treatment of certain diseases, and for speeding up recovery after exercise. Moreover, there is weak evidence that flossing might have a superior conditioning (warm-up) effect compared to stretching when the goal is to improve range of motion or certain aspects of muscle strength, while no such superior effect has been reported when compared to foam rolling.

OBJECTIVES: The symptomatic reduction of exercise-induced delayed onset muscle soreness (DOMS) is of great interest in the fields of Sports Medicine and Physical Therapy. At this time, few therapeutic interventions have proven their effectiveness. One of the most promising interventions is Compression Therapy. The object of this study is Tissue Flossing, a therapeutic short-term compression method and whether its post-exercise application can reduce the extent of perceived DOMS. DESIGN: randomized, controlled, and double-blind pilot cross-over trial. METHODS: Participants (n = 17) without any musculoskeletal injuries were recruited from university students. Participants performed an exercise protocol and obtained the intervention subsequently on one of both arms. Participants had to return for a second day to perform the whole procedure again, this time receiving the flossing intervention on the other arm. At both time points their opposite arms served as the control. The primary outcome measure was a patient reported visual analogue scale 100mm. RESULTS: The mean value of DOMS of the flossed arm was 42mm compared to the non-flossed arm with 48mm. Differences were found to be statistically significant at 24 hours- (p=0,036; α=0.05), as well as at 48 hours post-intervention (p=0,035; α=0.05). Effect sizes were dz=0,408 at 24 hours-and dz=0,411 at 48 hours post-intervention. The clean language effect size was 0.66. CONCLUSIONS: Tissue flossing appears to be an effective method for treating DOMS which is slightly less effective but much more practicable than gold standard treatment.

Purpose: The aim was to identify benefits of compression garments used for recovery of exercised-induced muscle damage. Methods: Computer-based literature research was performed in September 2015 using four online databases: Medline (PubMed), Cochrane, WOS (Web Of Science) and Scopus. The analysis of risk of bias was completed in accordance with the Cochrane Collaboration Guidelines. Mean differences and 95% confidence intervals were calculated with Hedges' g for continuous outcomes. A random effect meta-analysis model was used. Systematic differences (heterogeneity) were assessed with I(2) statistic. Results: Most results obtained had high heterogeneity, thus their interpretation should be careful. Our findings showed that creatine kinase (standard mean difference=-0.02, 9 studies) was unaffected when using compression garments for recovery purposes. In contrast, blood lactate concentration was increased (standard mean difference=0.98, 5 studies). Applying compression reduced lactate dehydrogenase (standard mean difference=-0.52, 2 studies), muscle swelling (standard mean difference=-0.73, 5 studies) and perceptual measurements (standard mean difference=-0.43, 15 studies). Analyses of power (standard mean difference=1.63, 5 studies) and strength (standard mean difference=1.18, 8 studies) indicate faster recovery of muscle function after exercise. Conclusions: These results suggest that the application of compression clothing may aid in the recovery of exercise induced muscle damage, although the findings need corroboration.

Objectives: To systematically search and assess studies that have combined blood flow restriction (BFR) with exercise, and to perform meta-analysis of the reported results to quantify the effectiveness of BFR exercise on muscle strength and hypertrophy. Design: A systematic review. Methods: A computer assisted database search was conducted for articles investigating the effect of exercise combined with BFR on muscle hypertrophy and strength. A total of 916 hits were screened in order based on title, abstract, and full article, resulting in 47 articles that fit the review criteria. Results: A total of 400 participants were included from 19 different studies measuring muscle strength increases when exercise is combined with BFR. Exercise was separated into aerobic and resistance exercise. Resulting from BFR aerobic exercise, there was a mean strength improvement of 0.4Nm between the experimental group and control group, while BFR resistance exercise resulted in a mean improvement of 0.3kg. A total of 377 participants were included in 19 studies measuring muscle size increase (cross sectional area) when exercise was combined with BFR. The mean difference in muscle size between the experimental group and control group was 0.4cm(2). Conclusion: Current evidence suggests that the addition of BFR to dynamic exercise training is effective for augmenting changes in both muscle strength and size. This effect was consistent for both resistance training and aerobically-based exercise, although the effect sizes varied. The magnitude of observed changes are noteworthy, particularly considering the relatively short duration of the average intervention.

Attenuated functional exercise capacity in elderly and diseased populations is a common problem, and stems primarily from physical inactivity. Decreased function and exercise capacity can be restored by maintaining muscular strength and mass, which are key factors in an independent and healthy life. Resistance exercise has been used to prevent muscle loss and improve muscular strength and mass. However, the intensities necessary for traditional resistance training to increase muscular strength and mass may be contraindicated for some at risk populations, such as diseased populations and the elderly. Therefore, an alternative exercise modality is required. Recently, blood flow restriction (BFR) with low intensity resistance exercise (LIRE) has been used for such special populations to improve their function and exercise capacity. Although BFR+LIRE has been intensively studied for a decade, a comprehensive review detailing the effects of BFR+LIRE on both skeletal muscle and vascular function is not available. Therefore, the purpose of this review is to discuss previous studies documenting the effects of BFR+LIRE on hormonal and transcriptional factors in muscle hypertrophy and vascular function, including changes in hemodynamics, and endothelial function.

Zusammenfassung Zusammenhang Flossing ist eine Behandlungsmethode um die Beweglichkeit, Leistungsfähigkeit und Regeneration zu verbessern sowie um Schmerzen, Ödeme und Verletzungsrisiken zu reduzieren. Ziel Welche Auswirkungen hat Flossing auf die Regenerationsfähigkeit nach Kraftausdauer-Belastungen und den wahrgenommenen Muskelkaterschmerz? Methodik 42 aktive, gesunde weibliche und männliche Probanden wurden randomisiert in eine Kontrollgruppe (n = 21) und Flossinggruppe (n = 21) eingeteilt. Für alle Probanden galt der gleiche Ablauf des Testprozedere: Am Mess-Zeitpunkt 1 (M1) absolvierte jeder Teilnehmer an der Beinpresse einbeinig so viele Wiederholungen wie möglich mit 65 % des Ein-Wiederholungs-Maximums (1 RM). Zwischen M1 und M2 wurde ein Ermüdungsprotokoll (3* so viele Wiederholungen wie möglich mit 65 % des 1 RM einbeinig an der Beinpresse) durchgeführt. Zum Zeitpunkt M2 (sofort nach dem Ermüdungsprogramm), M3 (30 Minuten nach dem Ermüdungsprogramm) und M4 (60 Minuten nach dem Ermüdungsprogramm) wurden erneut die maximalen Wiederholungen mit 65 % des 1 RM erfasst. Zwischen M2 und M3 erhielten die Probanden der Flossinggruppe eine dreimalige Anwendung mit dem Flossingband als Regenerationsmaßnahme für je zwei Minuten. 12 h, 24 h, 36 h, 48 h, 60 h und 72 h nach der letzten Messung wurde jeweils der Muskelkaterschmerz mit der numerischen Ratingskala (NRS) (0 – 10) und „Likert-Muscle-Scale“ erfasst. Ergebnisse Über alle vier Mess-Zeitpunkte zeigte sich kein signifikanter Effekt zugunsten der Flossinggruppe im Vergleich zur Kontrollgruppe. Die „Likert-Muscle-Scale“ ergab kein signifikantes Ergebnis. Lediglich nach 36 h zeigten sich niedrigere NRS-Werte in der Flossinggruppe im Vergleich zur Kontrollgruppe (p = 0,044). Schlussfolgerung Flossing beeinflusst die Regenerationsfähigkeit nach Kraftausdauer-Belastungen weder positiv noch negativ. Flossing hat keinen Effekt auf die Schmerzwahrnehmung bei Muskelkater.

Objectives: Previous results from our laboratory suggest that band flossing results in increased ankle range of motion (ROM) and jump performance 5-min following application. However, the time-course of such benefits is yet to be examined. Design: Parallel group design. Setting: University laboratory. Participants: 69 recreational athletes (32 male/37 female). Main outcome measures: Participants performed a weight-bearing lunge test (WBLT), a counter-movement jump (CMJ) and a 15 m sprint test (SPRINT) pre and up to 45-min post application of a floss band to both ankles (FLOSS) or without flossing of the ankle joints (CON). Results: There was a significant intervention × time interaction in favour of FLOSS when compared to CON for the WBLT (p < 0.05). These results were associated with trivial to small effect sizes at all time points. Small, but non-significant (p > 0.05) benefits were seen for FLOSS when compared to CON for CMJ force (mean ± 90%CI: 89 ± 101 N) and 15 m SPRINT times (-0.06 ± 0.04 s) at 45-min post. Conclusion: There is a trend towards a benefit for the use of floss bands applied to the ankle joint to improve ROM, jump and sprint performance in recreational athletes for up to 45-min following their application.

Objectives: Tissue compression and partial vascular occlusion using band flossing results in re-perfusion of blood to the muscle tissue that may ultimately increase range of motion (ROM) and reduce risk of injury. However, the effect of band flossing on ankle ROM and jump performance is yet to be evaluated. Design: In a crossover design, participants performed a number of tests pre and post the application of a floss band to one ankle (FLOSS), with the contralateral ankle acting as the control (CON). Setting: University laboratory. Participants: 52 recreational athletes (29 male/23 female). Main outcome measures: Pre and post measures included a weight-bearing lunge test (WLBT), ankle dorsiflexion (DF) and plantarflexion (PF) ROM, and single leg vertical jump height and velocity. Results: FLOSS resulted in significant enhancements in all test measures pre to post (p < 0.01), with no significant changes pre to post for CON (p > 0.05). All pre to post changes were associated with small effect sizes for FLOSS compared to CON. Conclusion: Floss bands applied to the ankle increase dorsiflexion and plantarflexion ROM and improve single-leg jump performance in recreational athletes. The results from this study suggest that floss bands may be used for injury prevention and athletic performance.

This study aimed to collate current evidence regarding the efficacy of various blood flow restriction (BFR) strategies for well-trained athletes, and to provide insight regarding how such strategies can be used by these populations. Review article. Studies that had investigated the acute or adaptive responses to BFR interventions in athletic participants were identified from searches in MEDLINE (PubMed), SPORTDiscus (EBSCO) and Google Scholar databases up to April 2015. The reference lists of identified papers were also examined for relevant studies. Twelve papers were identified from 11 separate investigations that had assessed acute and adaptive responses to BFR in athletic cohorts. Of these, 7 papers observed enhanced hypertrophic and/or strength responses and 2 reported alterations in the acute responses to low-load resistance exercise when combined with BFR. One paper had examined the adaptive responses to moderate-load resistance training with BFR, 1 noted improved training responses to low-work rate BFR cardiovascular exercise, and 1 reported on a case of injury following BFR exercise in an athlete. Current evidence suggests that low-load resistance training with BFR can enhance muscle hypertrophy and strength in well-trained athletes, who would not normally benefit from using light loads. For healthy athletes, low-load BFR resistance training performed in conjunction with normal high-load training may provide an additional stimulus for muscular development. As low-load BFR resistance exercise does not appear to cause measureable muscle damage, supplementing normal high-load training using this novel strategy may elicit beneficial muscular responses in healthy athletes.

Blood flow restriction training has proven to be effective, but it is not well known and is limited by initially producing discomfort. Blood flow restriction (BFR) induces hypoxia and metabolic effects, as well as reduction of proteolysis and induction of anabolic processes. Growth hormone levels are regularly increased. Controversies exist concerning neuromuscular effects. Twenty--eight of 30 studies, showed an increase in strength usually associated with muscle hypertrophy in both men and women, although data for women are sparse. Initial reports exist on positive effects on bone health after measuring rises in bone markers. A gain in strength has also been reported in non--occluded muscles after BFR training. BFR without training can lead to a rise in strength and reduce atrophy in knee extensor muscles during immobilisation. Controversial results have been observed concerning changes in aerobic capacity. Up to now no standard BFR training guidelines exist. Occlusion pressure, intensity of training, number of sets and duration of a training unit remain unclear. Presently, an occlusion pressure of 150 mmHg may be recommended with an intensity of 20 % 1--repetition maximum (1 RM), and wider cuffs are more efficient than narrow ones. Between training sets BFR should be continued. Rheologic investigations after BFR have shown no evidence for increased risk of thrombosis, when studying possible contraindications. Safety aspects for older patients must be more thoroughly addressed. The low--intensity needed may establish this training method in cardiac and pulmonary patients after future research.
