The purpose of this study was to determine the effects of calf compression sleeves on running performance and on calf tissue oxygen saturation (StO2) at rest before exercise and during recovery period. 14 moderately trained athletes completed 2 identical sessions of treadmill running with and without calf compression sleeves in randomized order. Each session comprised: 15 min at rest, 30 min at 60% maximal aerobic velocity determined beforehand, 15 min of passive recovery, a running time to exhaustion at 100% maximal aerobic velocity, and 30 min of passive recovery. Calf StO2 was determined by near infra-red spectroscopy and running performance by the time to exhaustion. Compression sleeves increased significantly StO2 at rest before exercise (+ 6.4±1.9%) and during recovery from exercise (+ 7.4±1.7% and + 10.7±1.8% at 20th and 30th min of the last recovery period, respectively). No difference was observed between the times to exhaustion performed with and without compression sleeves (269.4±18.4 s and 263.3±19.8 s, respectively). Within the framework of this study, the compression sleeves do not improve running performance in tlim. However the StO2 results argue for further interest of this garment during effort recovery.
Aim. The purpose was to examine the changes in tissue oxygen saturation (StO2) in response to the application of different commercially available calf compression sleeves. Methods. Eight subjects came to the laboratory to complete a session in seated position including 10 min of quiet rest followed by 3 min measuring calf StO2 without compression sleeves and then alternating of 3 min of passive rest and 3 min measuring StO2 with calf compression sleeves. A total of 15 different commercially available compression sleeves were studied in a randomized order. Calf StO2 was recorded using near-infrared spectroscopy. Results. StO2 was significantly increased with all compression sleeves (p < 0.05) compared with no compression (from +6.9% for the least effective to +22.6% for the most effective). Large differences were observed between compression sleeves (p < 0.05). StO2 was positively correlated with compression pressure (p < 0.05; r = 0.84). Conclusion. This study shows that wearing compression sleeves from various brands differently affects tissue oxygen saturation. Differences were linked to the compression pressure: higher compression pressures were associated with higher StO2.
Background: Effects of lower-limb compression garments on hemodynamics during walking or running remain unclear. Objectives: The purpose was to examine the changes in tissue oxygen saturation (StO2) with well-and tight-fitted compression sleeves -before, during and after an exercise on treadmill.
