Opposed Reviewers:
Response to Reviewers: Reviewer #1: The article is a very good synopsis of current literature and
methods for training the aerobic component in a highly sport-specific manner. Well done. A single
suggestion re: wording below.
Page 7 Line 37: Re-word, "...player numbers involve more continual involvement"; suggest: ...lower
player numbers results in more continual...
RESPONSE: Suggested change made.
Reviewer #2: The authors have done a great job with the edits to date, and I feel the article is now far
more focussed, and provides a good outline of the thought processes involved in the setting up of small
sided games.
My final revisions are very minor and mainly grammatical.
Page one the last sentence of the first introductory paragraph
This is very long and would benefit from some punctuation or slight rewording. I found myself having
to re-read it.
RESPONSE: The sentence has been shortened
Page three Paragraph four. Sentence Despite this concern soccer drill intensities
would it be better to add (as measured by heart rate if this is the measurement tool used ) or to reword
it to read relative intensities. Presumably absolute intensities of work would vary between
professional and amateur players.
RESPONSE: The sentence has been changed.
Page four Paragraph two sentence starting When conditioning, training load ....
the competitive structure could affect more than the repetition duration eg the work rest ratio etc .
Could a better ending to the sentence be
if it interferes too much with the targeted physiological response.
RESPONSE: The paragraph discusses how a competition structure can affect repetition numbers and in
doing so, the repetition duration. Therefore, I believe the sentence has to specifically refer to
‘repetition duration’ rather than the generic physiological response.
Paragraph three Sentence starting Normal small sided games are normally.
To avoid the double use of normally it may be best to start..Traditional small sided games.
RESPONSE: ‘Normally’ has been changed to ‘generally’.
Figure 1 This is a really good attempt to outline the thought processes involved in setting up the games .
Do the authors feel that work/rest ratio needs to be included somewhere, maybe in the duration boxes.
I have found that inappropriate work/rest ratios can adversely affect the adaptations achieved with
this form of training, and it is included in my planning processes.
RESPONSE: Work:Rest ratio added to figure.

SUMMARY
Utilising soccer drills for conditioning has considerable benefits. However, the practicalities of
conducting such sessions are more challenging than non-soccer specific conditioning methods. This
article examines factors that affect the physical nature of soccer drills, and provides guidance on how
to optimise training structure when utilising soccer drills for physiological development.
INTRODUCTION
Physiological development plays a crucial role in defining a soccer player’s potential match
performance and has been shown to correlate with playing standard (4,37) and performance (4). In
particular, training programs aimed at improving aerobic capacities have been shown to enhance
aspects of soccer performance, such as the time spent at high exercise intensities and involvements in
play (14). The physical nature of certain soccer drills used in training suggests they may be suited to
improving a player’s endurance capacities. Such soccer drills contain many of the elements of soccer
match play, such as passing, dribbling skills and scoring, but typically involve reduced player numbers
and/or modified rules. The use of soccer drills for physiological development has recently gained
increasing popularity, with support from scientific literature (13,15,27) and empirical evidence from
successful teams (33). It has been demonstrated that several soccer drills have the potential to elicit
intensities suitable for developing soccer endurance at elite and recreational levels (21) and in both
sexes (22). Furthermore, training programs involving soccer drills have been shown to be equally
effective in improving physiological factors important to soccer performance as generic aerobic
training (15,27). The voluntary nature of movement during soccer drills meant that there was concern
that some players may train at inappropriate exercise intensities for conditioning. However, recent
results (19,20,26) suggest that soccer drills can produce sufficiently similar exercise intensities across
different players, and repetitions to warrant their application for physical training.
Beyond the obvious advantage of increasing training efficiency via combined technical and
physiological training, utilisation of soccer drills has several advantages over more generic
conditioning methods, such as running without a ball. Motivation of the players is improved when
soccer and competition are involved (3). Also, more similar movement types, and patterns in soccer
drills may also lead to a greater transfer to match specific fitness. Enhanced movement efficiency is
particularly key for unorthodox forms of locomotion, such as side and backward movements, which
are frequently performed in soccer drills (28). Furthermore, the metabolic consequences of intermittent
exercise, as used in soccer drills and competition, have been shown to be different from continuous
exercise at the same average intensity (9). Despite these significant benefits, generic physical training
is still prevalent at all levels of the sport. This may be in part due to the greater difficulty in controlling

training load, and the increased organisation demands when using soccer drills compared to generic
physical sessions. Table 1 summarises the benefits and disadvantages of utilising soccer drills and
generic conditioning methods. The present article aims to review research concerning conditioning
with soccer drills, and provide practical guidance on how to optimise such sessions.
Table 1. Advantages and disadvantages associated with physical training using soccer drills and generic running.
TRAINING LOAD DURING SOCCER DRILLS
During physical training, it is paramount that training load, consisting of training intensity and
duration, is appropriate for the intended physiological and performance adaptations. Control over
training intensity is achieved during generic conditioning by specifying distance and/or duration
parameters of the exercise. The voluntary nature of movement in soccer drills means the control over
intensity is potentially less precise. However, evidence suggests a coach can attempt to control the
intensity of soccer drills by selecting specific drills, and by manipulating parameters of the soccer drill
(20,26). Factors that can influence the intensity of soccer drills include the type of drill, player
numbers, player motivation, pitch size and rule alterations.
The type of soccer drill is often modified by adjusting the number of players within a team. The
literature presents a consistent trend between playing intensity and number of players during small-
sided games, with lower playing numbers resulting in higher exercise intensities (19,20,26). Video
analysis has shown that reducing player numbers results in more continual involvement in play and
relatively more time spent performing higher intensity activities, such as sprinting (11,12,24). In
accordance, 8-aside to 5-aside drills (6,19,20,26,27,31) have often been reported to result in intensities
appropriate for lactate threshold development (~ 85-90% HRmax; 11), whereas 4-aside and 3-aside
games (2,6,14,17,19,20,27,31) consistently produce intensities deemed optimal for O2max
development (90-95% HRmax; 11). Blood lactate and perceived exertion responses indicate that 2v2
drills (1,19,20,29) are suited to anaerobic training. All these training formats are considered critical in
developing soccer endurance (4,14). Discussion of optimal endurance training methods for soccer
performance is beyond the scope of this article, but have been extensively reviewed in previous
literature (3,14,32). Table 2 shows the recommended training loads and soccer drills that have been
reported to produce suitable intensities for the aforementioned endurance training methods.

Training loads adapted from Bompa (5).
Possession games, without goalkeepers, have been shown to increase drill intensity (31). This may be
due to fewer breaks in play and the lack of positional movement restrictions. Therefore, possession

drills may allow coaches to train higher threshold adaptations with relatively larger team sizes. In
addition, rule changes, such as restricting the number of consecutive touches (3,30), man-to-man
marking (1,30) and using support players, have been reported to cause an increase in intensity (1).
It has generally been found that larger pitches produce greater intensities (4,17,23,26), presumably
because players cover greater distances and play is more open on the larger pitches. Table 3 shows the
pitch sizes utilised by Rampinini et al. (26) for various small sided games when examining the effects
of pitch size.
Table 3. Pitch sizes considered small, medium and large for various soccer drills, reported by Rampinini et al.
(26) and Owen et al. (23).
Authors (30,31) have reported, and empirically it is often seen, that coach encouragement increases
training intensity. Indeed, Rampinini et al. (26) reported that coach encouragement was the dominant
variable on playing intensity, when examining the effects of varying pitch size, player numbers and
coach encouragement. Therefore, coaches should aim to maximise motivational techniques when high
training intensities are required. Factors that can be used to enhance motivation include coaching staff
providing encouragement, using a competitive playing structure and providing feedback to the players
about intensity (8).
A factor that can influence soccer drill intensity that cannot be controlled by the coach, is the standard
of the players. Players of low technical ability may not be able to produce high training intensities
during soccer drills because play is often disrupted, and does not flow across the pitch quickly. Despite
this concern, relative intensities have been reported to be similar between amateur and professional
players during the same soccer drills (2,21,26,27). Table 4 shows intensities of soccer drills reported in
the literature with details of the aforementioned factors that can influence intensity.
Table 4. Soccer drill parameters and intensities reported in the literature.
ORGANISATION OF SOCCER DRILL CONDITIONING SESSIONS
The practicalities of organising a soccer drill session are much more daunting than that of a generic
physical session. With generic conditioning, the main practicalities concern producing the appropriate
training load. However, soccer drills have an additional number of factors to consider, which are often
dictated by training circumstances.

Total player numbers dictate what type of soccer drills can be utilised because the team sizes used
must be a dividable number of the total number of players. For example, 16 players would require 8, 4
or 2-aside teams. Player numbers and team size also effect how many teams are formed. If more than
two teams are formed, multiple drills have to be set up where teams play simultaneously on different
pitches. In addition, the number of goalkeepers and goalposts influences what type of drills can be
used. Possession drills without goalkeepers can be utilised in scenarios where there are insufficient
goalkeepers/ goalposts for the number of pitches needed. Once the drills that suit the training
circumstances have been identified, the coach must select those that have the potential to produce the
desired work intensities. The coach must then select appropriate drill parameters, such as pitch size
and rules, to produce the desired intensity.
The number of teams, and different drills can affect how many repetitions are performed, if a
competitive structure is to be used. A competitive structure involves all teams playing each other an
equal number of times. Such a structure can aid motivation levels by increasing competition and
placing increased significance on the results. For example, if there are 4 teams, the number of
repetitions would be multiples of 3. However, if different types of drills are utilised, a competitive
structure would require that all teams play each other an equal amount of times, and that each team
plays the same amount of the different soccer drills. For example, if there were 4 teams with 2 playing
3-aside and the other 2 teams playing a possession game, multiples of 6 repetitions should be
administered so each team plays all the opposition teams on both drills. The effect of a competitive
structure on repetition numbers often requires that repetition durations are manipulated from what are
typically used to produce the appropriate training load. When conditioning, training load must always
remain the priority, and therefore a competitive structure should not be used if it interferes too much
with an appropriate repetition duration.
Soccer drills allow simultaneous physical and technical development. Therefore, when possible the
soccer drills utilised should contain the tactics/ technical elements desired by the coach. Normal small-
sided games are generally desirable because they closely replicate the demand of match play.
Possession drills are often used if the coach wants to emphasise pressurising opponents or maintaining
possession of the ball. Figure 1 illustrates the decision process a coach must use to produce the correct
training parameters when using soccer drills for conditioning.

CONCLUSION
Recent evidence has supported the potential of utilising soccer drills to train physical capacities of
soccer players and thus provide simultaneous skill and fitness training. Utilising soccer drills for
conditioning has key advantages when compared with generic physical training, such as enhanced
motivation and greater transfer to match specific fitness. However, their utilisation can present a
challenge in producing optimal work intensities and determining appropriate training structures.
Information within this article should aid coaches in choosing and organising soccer drills, and
training structures for physiological development.

... Similarly, participants in HIIT underwent a more intense first day (4 sets of 3 minutes with 15-second highintensity and 15-second recovery intervals) and a more extensive second day (4 sets of 3 minutes each). These training interventions are in line with recommendations for the use of both SSG and HIIT, supported by previous studies (Little and Williams, 2006;Little, 2009;Buchheit and Laursen, 2013a;Buchheit and Laursen, 2013a). In the case of 6v6, it was used to moderate heart rate responses, allowing for longer practice sessions, while the decrease in intensity in HIIT on the second day followed the same rationale (Little and Williams, 2006;Little, 2009;Buchheit and Laursen, 2013a;Buchheit and Laursen, 2013b). ...

The aim of this study was twofold: (i) to compare physical fitness adaptations following small-sided games (SSG) and running-based high-intensity interval training (HIIT), considering sex interactions ; and (ii) to describe intra-individual variations of adaptations in both men and women developmental/trained soccer players over an 8-week randomized parallel study design involving 25 women and 27 men. Pre and post-intervention assessments included countermovement jump (CMJ), 10-meter linear sprint test, change-of-direction (COD) deficit, and final velocity at 30-15 Intermittent Fitness Test (VIFT). Significant interactions between time, groups and sex were found in 10-m sprint (F1,48 = 6.042; p = 0.018; = 0.112). No significant interactions between time, groups and sex were found in CMJ (F F1,48 = 0.609; p = 0.439; = 0.013), COD deficit (F F1,48 = 2.718; p = 0.106; = 0.054) and VIFT (F F1,48 = 1.141; p = 0.291; = 0.023). Significant interactions were found between time and sex in CMJ (F F1,48 = 29.342; p < 0.001; = 0.379), 10-m sprint (F F1,48 = 4.359; p = 0.042; = 0.083), COD deficit (F F1,48 = 5.066; p = 0.029; = 0.095) and VIFT (F F1,48 = 11.248; p = 0.002; = 0.190). In conclusion, this study suggests similar effects of HIIT in both sexes. However, for women, SSG may entail less efficacy and more inter-individual variability compared to men. Therefore , HIIT could potentially be a better solution for women, whereas both training approaches were equally effective in men.
... The significance of small-sided games lies in their ability to provide coaches with scenarios that closely simulate real football competition. This multifaceted approach targets various energy systems simultaneously (Little T. , 2009), alongside addressing the technical and tactical aspects specific to football. Small-sided games are structured as matches with either balanced or unbalanced numbers of players, organized according to the desired objective. ...

This study aimed to compare the effects of small-sided games (4 vs. 4) versus training in the Hoof technical circuit on improving aerobic capacity in soccer players. The study included 16 soccer players with similar characteristics (average age: 24.7 ± 3.28 years, average weight: 76.4 ± 4.2 kg, average height: 180.6 ± 3.2 cm), divided into two distinct training methods: small-sided games (4 vs. 4) and circuit training using the Hoof technical circuit. The results, analyzed statistically using SPSS, indicated no statistically significant differences between the two integrated training methods—small-sided games (4 vs. 4) and the Hoof technical circuit—in enhancing aerobic capacities such as maximal aerobic speed (VMA) and maximal oxygen consumption (VO2max). Both methods contributed to improving aerobic capacity at comparable levels, with a slight advantage observed in the post-test compared to the pre-test for both groups.
... Small-sided games are played on reduced field areas with fewer players and modified rules, with the capability of replicating the movement requirements, physiological intensity, and technical demands of an actual match play (Hill-Haas, Dawson, Impellizzeri & Coutts, 2011). It has been suggested that small-sided games play a significant role in developing technical skills and tactical awareness (Little, 2009). The popularity of small-sided games as a training modality in soccer is primarily due to their practicability, low cost, and overall similarity with competitive matchplay. ...

Talent identification and development in youth soccer are complex and multidimensional processes. This scoping review aimed to explore the current literature regarding the variables used in the talent identification and development process in soccer. This study was developed referring to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) guidelines. Pubmed, Web of Science and Scopus databases were searched from September to October 2023. Only peer-reviewed journal articles published in English were included, with no limitation regarding the publication year. Through the initial search 774 records were identified and 190 articles met the inclusion criteria. The main finding was that most studies assessed speed (52.1%), maturity (42.1%), lower limbs strength (40.5%), aerobic capacity (35.8%), agility (32.6%), technical skills (16.8%), and tactical skills (14.2%). Male athletes were investigated in 162 studies (85.3%), whereas seven studies (3.7%) were conducted with females only, and seven articles (3.7%) with males and females. Fourteen studies (7.4%) did not specify the sex of the participants. In conclusion, findings indicate that physical performance and maturity factors are the most investigated variables regarding talent identification and development in soccer. This review highlights the importance of considering physical performance tests and technical/tactical skills, along with maturity status assessment, as key tools in talent identification programs. Current talent identification practices in soccer may benefit from a more balanced approach that includes physical, technical, tactical, maturational, and psychological assessments to capture a broader range of player potential.

Background: Football is a versatile team sport that requires a range of physical characteristics, including flexibility, power, strength, endurance, speed, repetitive sprinting, quickness-agility and technique-tactics. Developing all these features at the same time, especially in the pre-season, when players are in a deconditioning state, returning to training after a rest period; it is quite difficult for coaches and performance trainers. Aim: The aim of this study is to examine the effects of strength and endurance training applied simultaneously on some physical, physiological and psychological parameters in young football players. Methods: U19 age group players were included in the research group, 24 male football players who played amateur or professionally licensed football for at least 5 years and trained for an average of 2 hours a day, 5 days a week; (Endurance+Strength Group n=12, Strength+Endurance Group n=12). In the study, 1 RM strength test, agility, speed, technique, decision-making skills and endurance tests were taken from the participants. In our study, with the pretest-posttest measurement method; Yo-Yo test, Loughborough Soccer Passing Test (LSPT), Illinois Agility Test, 30 meters Speed Test, Maximal (1RM) Strength Test, Jumping Test (CMJ) were applied. Results: The findings obtained when the performance values of football players within and between groups were evaluated statistically; It has been determined that the positive increase in endurance, strength, sprint, agility/speediness, jump and lspt pass test values as a percentage (%) was seen in the group that applied strength training before endurance training. Conclusion: The application of strength training before endurance training in 'concurrent' training model applications in young football players; on performance values; It has been determined that endurance training has more effect than applying it before strength training. According to these results, it is thought that designing the programs by taking this situation into consideration in the training program adjustments can contribute more to the coaches and the player group in terms of sportive efficiency.

z Takım sporlarında mücadele eden sporcuların performans değerlendirmelerinde ve buna bağlı olarak performans arttırma konusunda antrenörlere ve kondisyonerlere yön verecek bu çalışmada amacımız, yüksek şiddetli dar alan oyunlarının (2x2, 3x3); futbolcuların mevkilerine göre anaerobik eşik ve reaksiyon sürati (5metre) üzerine etkilerini araştırmaktır. Araştırmanın örneklem grubunun boy ortalamaları 178.60±5.18cm, vücut ağırıkları ortalamaları 72±4.10 kg, BKİ ortalamaları 22.60±0,99, yaşları ortalamaları 23.45±3.5 yıldır. En az 2 yıldır profesyonel lisanslı olarak futbol oynayan, haftanın 5 günü, günde 2 saat antrenman yapan 20 erkek futbolcu araştırmanın örneklem grubunu oluşturmaktadır. Araştırmada, t testinin (ön test-son test) parametrik olmayan alternatifi olan Wilcoxon T testi modeli kullanılmıştır. Anaerobik eşik 4 mmol/l kriter alınarak koşu ve kalp hızlarını Microsoft Excel Office programında polinom hesabı ile belirlenmiştir. Reaksiyon Süratini belirlemek için 5m sprint testinden elde edilen 2 derecenin en iyisi alınmıştır. Araştırmamıza katılan futbolculara 8 hafta süresince haftada 2 gün takım antrenmanlarının içerisinde yüksek şiddetli dar alan oyunları uygulanmış, ön test ve son testleri 2 ay (8 hafta) ara ile haftanın aynı günü ve saatleri (10:00-16:00) arasında gerçekleştirilmiştir. Araştırma bulgularına göre, profesyonel futbolcularda yüksek şiddetli dar alan oyunları sonrasında anaerobik eşik performanslarında istatistiki olarak anlamlı düzeyde artış meydana geldiği belirlenmiştir (P<0.05), reaksiyon sürati performansı üzerinde ön test ve son test farkına bakıldığında ise istatistiki olarak fark bulunamamıştır (p>0,05). Ancak reaksiyon sürati performans ortalama değerleri göz önüne alındığında; ön test (1,10sn) ve son test (1,04sn) arasında olumlu bir etki olduğu, tespit edilmiştir. Buradan hareketle futbolda yapılacak antrenmanlarda bazı fizyolojik ve motor becerilerin gelişiminde dar alan oyunlarının kullanılması aynı anda birden fazla özelliği geliştirme açısından ve antrenman zamanının daha verimli kullanımı açısından faydalı olabilir.

Aim. This study was designed to compare the effects of 8-weeks of small-sided games versus high-intensity interval training on the internal training-load and physiological responses in the amateur soccer players' Under-17. Methods.15 participants (aged 16.2 ± 0.2years, height 173 ± 2.5cm, weight, 56.4 ± 2.4Kg, body mass index 19.01 ± 1.3Kg/m2) performed pre and post measurements in training program for 8-weeks of small-sided games and high-intensity interval training. Measuring sessions in (resting heart-rate, maximum heart-rate, reserve heart-rate bpm and training-load with Borg rating of perceived exertion scale. Results. The results indicated that the small-sided games (4vs4) displayed significantly higher heart-rate values in (maximum heart-rate, reserve heart-rate) and rating of perceived exertion indicators (monotony and constraint) compared with the high-intensity interval training (30/30s) (p <0.05), in contrast to resting heart-rate and weekly load, which did not record statistical differences between both groups (p <0.05). Conclusions. These results indicate that the small-sided games (4vs4) group achieved greater improvements than the high-intensity interval training (30/30s) group, However, coaches should be aware that both training methods are applicable methodologies to improve in season heart-rate responses and training-load in amateur soccer players' under-17.

Purpose: The aim of this study was 2-fold: (1) to examine the relationships between psychophysiological responses and locomotor demands with variations in technical performance during 2v2 and 4v4 conditioned games and (2) to compare psychophysiological and locomotor responses among players exhibiting higher and lower technical performance levels during the conditioned games. Methods: Twenty-four male youth soccer players (16.3 ± 0.8 y old) participating at the trained/developmental level underwent monitoring for psychophysiological responses (including heart rate, rating of perceived exertion, and visual analog scale), locomotor demands (such as distance covered), and technical performance variables (including successful and unsuccessful passes and shots, as well as lost balls) across 2v2 and 4v4 formats. These formats were applied 4 times within a single session and were replicated twice over 2 weeks. Results: Large correlations between the number of lost balls per minute and mean heart rate were found in both the 2v2 and 4v4 games (r = .586 and r = .665, respectively). Successful shots were inversely and largely correlated with mean heart rate (r = −.518) in 4v4 games. The number of interceptions per minute was inversely and significantly correlated with the visual analog scale in 2v2 and 4v4 games (r = −.455 and r = −.710, respectively). The frequency of lost balls was significantly higher among players who attained a higher mean heart rate (2v2: +42.9%, P = .031, d = −0.965; 4v4: +57.1%, P < .001, d = −2.072). Conclusions: Coaches should be aware that highly psychophysiologically demanding scenarios may significantly impair technical performance. Therefore, prioritizing technical performance by deliberately adjusting the intensity should be considered.

To establish the net energy cost of dribbling a soccer ball, eight males ran on a treadmill while dribbling a ball against a rebound box. Oxygen uptake, perceived exertion, and blood lactate levels were measured and compared with results from subjects running without dribbling. Results are discussed. (Author/DF)

The major purpose of the present study was to examine whether there exists a relationship between preseasonal physiological tests and performance results in the soccer league. Further, it investigated maximal oxygen uptake and maximal strength in proportion to body mass for soccer players. A secondary aim was to establish some normative data of Norwegian elite soccer players. Two teams from the Norwegian elite soccer league participated in the study. The present study supports previous investigations indicating a positive relationship between maximal aerobic capacity, physical strength, and performance results in the elite soccer league. It is concluded that for soccer players, maximal oxygen uptake should be expressed in relation to body mass raised to the power of 0.75 and maximal strength in relation to body mass raised to the power of 0.67, when the aim is to evaluate maximal aerobic capacity when running and strength capacity among players with different body mass. Midfield players had significantly higher maximal oxygen uptake compared with defense players using the traditional expression, mL x kg(-1) x min(-1), while no significant differences were found expressing maximal oxygen uptake either absolutely (L x min[-1]) or in relation to body mass raised to the power of 0.75 (mL x kg[-0.75] x min[-1]) among players grouped by position. There was a significant correlation (r = 0.61, P < 0.01) between squat IRM and vertical jump height. Vertical jump heights for defense and forward players were significantly higher compared with midfield players. Mean results from the laboratory test were 63.7 mL x kg(-1) x min(-1) or 188.6 mL x kg[-0.75] x min(-1) for maximal oxygen uptake, 150 kg or 8.0 kg x mb(-0.67) for 90 degrees squats, 79.9 kg or 4.4 kg x mb(-0.67) for bench press. Mean values of vertical jump height were 54.9 cm.

The present thesis is based on 14 original articles published in international journals (I-XIV, see page 8) and a summarizing review. The thesis deals with the physiological demands of soccer, with a particular focus on the physiological response to repeated intense exercise. In chapter I the specific issues are presented and in chapter II the physiological demands in soccer are discussed based on the results of the studies performed. Chapter III contains a short survey of the experiments performed to study specifically muscle metabolism and muscle fatigue with repeated intense muscle contractions. With reference to the topics covered in chapters II and III, fatigue during a soccer match is discussed in chapter IV, and chapter V deals with applications for physical training in soccer. Measurements have been performed during soccer matches and training, as well as in experiments simulating the activities of a soccer match. The information obtained has been compared to results from studies of the physical capacity of top-class soccer players and from laboratory experiments aimed at investigating metabolism and fatigue in intermittent exercise. Studies with whole-body and single muscle group exercises have been performed, the latter mainly with the application of a knee-extension model. In the studies on isolated muscle groups, biopsies taken from exercising muscles as well as arterial and femoral venous blood samples have allowed for detailed analysis of muscle ionic transportation and metabolism. In addition, the magnetic resonance technique has been used for the continuous determination of changes in muscle metabolites and pH during intermittent exercise. Analysis of activities during soccer matches showed that a top-class soccer player covers an average distance of approximately 11 km during a match. The distance differs highly between players and is partly related to the position in a team. Midfield players run more at low speed than defenders and forwards, whereas no difference appears to exist between groups when comparing the distance covered at high speed. The distance covered at high speed is the same in the beginning as in the end of a match. The total distance covered by a player during a soccer match is only to a limited extent a measure of the physiological demands on the player during the match. In addition to running, a player is engaged in many other energy demanding activities, i.e. tackling, jumping, accelerating and turning. A more precise evaluation of the total energy demand during a soccer match may be achieved by performing physiological measurements in connection with soccer matches (I).(ABSTRACT TRUNCATED AT 400 WORDS)

The aim of this study was to devise a laboratory-based protocol for a motorized treadmill that was representative of work rates observed during soccer match-play. Selected physiological responses to this soccer-specific intermittent exercise protocol were then compared with steady-rate exercise performed at the same average speed. Seven male university soccer players (mean ± s: age 24 ± 2 years, height 1.78 ± 0.1 m, mass 72.2 ± 5.0 kg, V̇O(2max) 57.8 ± 4 ml/kg-1/min-1) completed a 45-min soccer-specific intermittent exercise protocol on a motorized treadmill. They also completed a continuous steady-rate exercise session for an identical period at the same average speed. The physiological responses to the laboratory-based soccer-specific protocol were similar to values previously observed for soccer match-play (oxygen consumption approximately 68% of maximum, heart rate 168 ± 10 beats/min-1). No significant differences were observed in oxygen consumption, heart rate, rectal temperature or sweat production rate between the two conditions. Average minute ventilation was greater (P < 0.05) in intermittent exercise (81.3 ± 0.2 l/min-1) than steady-rate exercise (72.4 ± 11.4 l/min-1). The rating of perceived exertion for the session as a whole was 15 ± 2 during soccer-specific intermittent exercise and 12 ± 1 for continuous exercise (P < 0.05). The physiological strain associated with the laboratory-based soccer-specific intermittent protocol was similar to that associated with 45 min of soccer match-play, based on the variables measured, indicating the relevance of the simulation as a model of match-play work rates. Soccer-specific intermittent exercise did not increase the demands placed on the aerobic energy systems compared to continuous exercise performed at the same average speed, although the results indicate that anaerobic energy provision is more important during intermittent than during continuous exercise at the same average speed.
