(2010) ABSTRACT (UK)The purpose of this study was to determine the effects of under-knee compression stockings of two different brands on sub maximal running performance in men runners. Using a withingroup study design, 6 moderately trained healthy athletes (31.0 ± 6.8 years) without lower-leg abnormities were randomly assigned to perform a treadmill test over 5km at 85% of their individual personal best time over 5000m of the last season with two different stockings (NIKE, SKINS) and without any stocking (Control). METHODS: Every subject had to perform the same running test at their own same running speed on three different testing days at the same day time at each day. Between every testing moment, participants added up 48 hours of recovery in daily routine. For every subject, first test was performed without stockings. The sequence of the following two performances was randomly selected. After standardised warm-up protocol, baseline lactate values (mmol·L -1 ) and heart rate (bpm) were determined. Additionally heart rate and perceived exertion were observed every 1000m. Lactate at end and after 2 min recovery, heart rate after 30sec, 60sec and 120sec of recovery, were also measured. RESULTS: No statistically significant differences were found for heart rate, except heart frequency at 1km (162.67 ± 5.85 (Control) vs. 159.33 ± 5.78 (NIKE) and 159.67 ± 8.57 (SKINS); p<0.05 (p=0.032)), blood lactate and BORG scale. Humidity (%) (37.73 ± 0.69 (Control) vs. 37.50 ± 0.67 (NIKE) and 37.02 ± 0.86 (SKINS)). CONCLUSION: No changes in heart rate, lactate values and perceived exertion were noted when wearing compression stockings.

Is There Evidence that Runners can Benefit from Wearing Compression Clothing?

“…Clearance of blood lactate following running exhibited a small positive effect (mean g = 0.29 ± 0.32; range -0.02 to 0.62 [10,13]).…”

“…Neither blood saturation and partial pressure of oxygen (mean g = -0.05 ± 0.20; range -0.37 to 0.31 [9,12,26] nor cardiac parameters, including heart rate, cardiac output, cardiac index, and stroke volume, were influenced to any great extent by the compression garments (mean g = 0.08 ± 0.37; range -0.48 to 1.77 [1, 3, 8-10, 12, 13, 15, 16, 18, 19, 21, 24, 42, 44]), although two studies did observe moderate-to-large positive effects on maximal heart rate (g = 1.77 [18]) and heart rate during submaximal running (g = 0.53 [10]). Body core temperature during and after running was affected to small and moderate extents by compression clothing in two studies [20,45], with no effect on body temperature (p = 0.00) (mean g = 0.24 ± 0.21; range 0.00-0.41 [20,45]).…”

“…Runners at various levels of performance and specializing in different events (from 800 m to marathons) wear socks, sleeves, shorts, and/or tights with compression to improve their performance [1][2][3] and facilitate recovery [4,5]. To date, the effects of compression clothing have been examined with a variety of running protocols, including short-term submaximal treadmill running [6][7][8][9][10][11], incremental treadmill tests to exhaustion [12][13][14][15][16][17], 10-km races [1], time to exhaustion at the pace used during a 10-km race [18], and 10-km submaximal running [14]. Few such investigations have involved real-life or simulated running competitions exceeding 1 hour in duration and conducted outdoors [2,3,19,20], while others have applied compression garments only during recovery from running for 12 [21], 48 [4,22], or 72 [5] h.…”

Eficácia das meias de compressão no desempenho e na recuperação do exercício: revisão narrativa

“…Rider et al 14 encontraram uma diferença significativa positiva na depuração de ácido láctico entre o grupo usando MC e o grupo placebo (8,3 ± 2,2 vs. 8,2 ± 2,5 mmol/L e 13,3 ± 2,9 vs. 14,8 ± mmol/L, respectivamente) no pós-exercício. No entanto, não foram observadas diferenças significativas nas concentrações de ácido láctico pós-exercício em Cabri et al 42 , utilizando MC em teste submáximo na esteira.…”
