The effects of compression garments on intermittent exercise performance and recovery on consecutive days.
ABSTRACT The aim of this study was to determine whether compression garments improve intermittent-sprint performance and aid performance or self-reported recovery from high-intensity efforts on consecutive days.
Following familiarization, 14 male rugby players performed two randomized testing conditions (with or without garments) involving consecutive days of a simulated team sport exercise protocol, separated by 24 h of recovery within each condition and 2 weeks between conditions. Each day involved an 80-min high-intensity exercise circuit, with exercise performance determined by repeated 20-m sprints and peak power on a cart dynamometer (single-man scrum machine). Measures of nude mass, heart rate, skin and tympanic temperature, and blood lactate (La-) were recorded throughout each day; also, creatine kinase (CK) and muscle soreness were recorded each day and 48 h following exercise.
No differences (P=.20 to 0.40) were present between conditions on either day of the exercise protocol for repeated 20-m sprint efforts or peak power on a cart dynamometer. Heart rate, tympanic temperature, and body mass did not significantly differ between conditions; however, skin temperature was higher under the compression garments. Although no differences (P=.50) in La- or CK were present, participants felt reduced levels of perceived muscle soreness in the ensuing 48 h postexercise when wearing the garments (2.5+/-1.7 vs 3.5+/-2.1 for garment and control; P=.01).
The use of compression garments did not improve or hamper simulated team-sport activity on consecutive days. Despite benefits of reduced self-reported muscle soreness when wearing garments during and following exercise each day, no improvements in performance or recovery were apparent.

ABSTRACT: Purpose. Compression garments are often worn during exercise and allegedly have ergogenic and/or physiological effects. In this study, we compared hemodynamics and running performance while wearing compression and loose-fit breeches. We hypothesized that in neutral-warm environment compression breeches impair performance by diminishing body cooling via evaporative sweat loss and redistributing blood from active musculature to skin leading to a larger rise in body temperature and prolonging recovery of hemodynamics after exercise. Methods. Changes in hemodynamics (leg blood flow, heart rate, and blood pressure during orthoclinostatic test), calf muscle tissue oxygenation, and skin and core temperatures were measured in response to 30 min running (simulation of aerobic training session) followed by maximal 400 m sprint (evaluation of running performance) in recreationally active females (25.1 ± 4.2 yrs; 63.0 ± 8.6 kg) wearing compression or loose-fit breeches in randomized fashion. Results. Wearing compression breeches resulted in larger skin temperature rise under the garment during exercise and recovery (by about 1 ∘ C, íµí± < 0.05; statistical power > 85%), while core temperature dynamics and other measured parameters including circulation, running performance, and sensations were similar compared to wearing loose-fit breeches (íµí± > 0.05). Conclusion. Compared with loose-fit breeches, compression breeches have neither positive nor negative physiological and performance effects for females running in thermoneutral environment.The Scientific World Journal 08/2014; 2014(353040).

ABSTRACT: The purpose of this study was to examine the effects of graduated compression sleeves on muscle performance during high-intensity exercise. Twenty-four resistance trained men were randomly assigned to one of two groups: compression sleeve (GCS, n=11) or placebo sleeve (GPS, n=13). Participants performed 4 sets of 10 unilateral maximal eccentric/concentric elbow flexion repetitions on an isokinetic dynamometer at 120° s-1 with 1 min of inter-set rest. Average torque, work and power were measured during concentric and eccentric actions.ANOVA revealed no significant interactions or main effects for group for any variable. However, values decreased significantly across sets for average torque (1st = 46.55 ± 11.11 Nm to 4th = 36.75 ± 8.78 Nm), average work (1st = 78.83 ± 18.49 J to 4th = 53.26 ± 10.04 J) and average power (1st = 52.3 ± 12.03 W to 4th = 32.59 ± 8.82 W). Therefore, the use of a graduated compression sleeve appears not enhance isokinetic elbow flexion muscle performance.International Journal of Sports Science & Coaching 12/2014; 9(5):985-992.
