Intermittent Sequential Pneumatic Compression (ISPC) has gained popularity as a recovery modality among athletes, particularly in high-performance cycling. This randomized sham-controlled crossover trial aimed to evaluate the effectiveness of a 30-minute high-pressure ISPC intervention compared to a sham condition on recovery markers in trained cyclists following a strenuous time trial.
Study Overview
The study included twenty-one male participants, with an average age of 22.8 years. The recovery protocol sequence was randomly assigned to each participant. Various recovery measures were assessed at baseline, one hour post-intervention, and at 24 and 48 hours post-exercise. These measures included isometric knee extension, cycling performance, quadriceps low-frequency fatigue, creatine kinase levels, and subjective assessments of fatigue, recovery, and muscle soreness.
Results
Results indicated that ISPC provided benefits in perceptions of recovery, muscle soreness, and fatigue, as well as improvements in low-frequency fatigue scores and maximal voluntary contraction of knee extension. However, these benefits did not translate into enhanced performance in subsequent time trials conducted 24 hours later. The study found no significant increase in creatine kinase activity following the fatigue protocol, suggesting that while ISPC may aid in acute recovery, it does not necessarily improve performance outcomes.
Conclusion
In conclusion, the use of ISPC appears to enhance acute subjective and neuromuscular recovery markers following a strenuous cycling effort. Despite the lack of performance advantage in short-duration cycling trials, ISPC may still be a valuable tool for athletes seeking to accelerate perceptual and neuromuscular recovery.
What this study does not show
This study does not demonstrate that ISPC leads to improved cycling performance in subsequent trials, despite positive effects on recovery markers.
