Abstract

The purpose of this study was to examine the changes in tissue oxygen saturation (StO2) with calf compression sleeves, before, during and after a cycling exercise.Eleven athletes came to the laboratory two times, to complete the same session with or without calf compression sleeves, in a randomized order. The session included a 15-min incremental cycling exercise: 3 min at each intensity - 40, 80, 120, 160 and 200 W, preceded (baseline) and followed (recovery) by a 10-min period at rest in seated position. Calf StO2 was recorded using near infrared spectroscopy during the three last min of the baseline period, during the cycling exercise and during the recovery period.Baseline StO2 was significantly increased with the compression sleeves (P0.001; +24.8±3.5%). During the cycling exercise, StO2 was significantly increased with the compression sleeves only at 40 W (P0.05; +8.2±3.7%) and 80 W (P0.05; +7.9±3.7%). At 120 W (P=0.23; +5.0±4.0%), 160 W (P=0.38; +3.9±4.1%) and 200 W (P=0.81; -0.1±4.9%), no significant difference was found with compression sleeves. During the recovery period, StO2 was significantly increased with the compression sleeves (1 to 10 min: P0.001; +10.5±1.3%).This study shows that wearing calf compression sleeves increases StO2 at rest (before and after an exercise) and at low intensities in cycling (40 W and 80 W). At high intensities (120 W and more), compression sleeves is not useful to increase StO2.

Abstract

During soccer matches, performance decrements have been reported that relate to both physical abilities and technical skills. To investigate the effects of low-frequency electrical stimulation LFES (VeinoplusSport®, Ad Rem Technology, France) administered during half-time recovery on performance alterations during the second half. Twenty-two highly trained young players undertook a soccer-match simulation (SAFT90). During half-time, they were randomly assigned to LFES group or Placebo group. Each half was split into 3 bouts of 12 minutes. Following each bout, maximal strike speed (MSS), sprint test (ST), maximal sprint accelerations (MA) and metabolic power (MP) were determined in both groups. Arterial (AF) and venous flows (VF) were measured at rest and at the end of half-time. LEFS group exhibited beneficial effects on performance compared to the Placebo group with a likely effect for MSS, ST, MA, and a possible effect for MP. AF and VF increased statistically more in LEFS group compared to Placebo group. The use of specific calf-pump LFES during half-time of a youth simulated soccer match attenuated the decrease in performance during the second half compared to Placebo group. This effect is most marked at the beginning of the second half with regards to explosive parameters. [ABSTRACT FROM AUTHOR]

Abstract

International audience; AIM: The purpose of this study was to examine the effects of a cycle competition on the large arteries stiffness, 24-hours after the end of the effort. METHODS: Two males elite cyclists were studied before and after performing a stage-race. Their heart rate (HR) was measured continuously during the two competition days. The impact of the competition on their vascular system was determined using the measure of pulse wave velocity (PWV), an index of regional arterial stiffness. HR and blood pressure were also measured before and 24-hours postexercise. RESULTS: During the race, mean cyclists HR were relatively similar. Changes in PWV and HR were found after competition: these measures increased for the offensive subject and decreased for the other. CONCLUSIONS: Despite their involvement in the same cycling competition, we suggest that the long-term effects induced by effort on arterial stiffness were inverted according to the subject's comportment during the race. This study should be completed by others measures in order to precise our results and to precise the possible link between arteries stiffness and the recovery kinetic process, both depending on the cardiovascular autonomic nervous system control.
