Intermittent Sequential Pneumatic Compression (ISPC) has become a popular recovery modality among athletes, particularly in high-performance cycling. This study, published in the International Journal of Sports Physiology and Performance, investigates the effectiveness of a 30-minute high-pressure ISPC intervention compared to a sham condition on recovery markers in trained cyclists.
The randomized controlled trial involved 21 male participants, with an average age of 22.8 years. The study employed a crossover design, where each participant underwent both the ISPC and sham conditions in a randomly assigned sequence. Recovery was assessed through various measures, including isometric knee extension, cycling performance during a 4-minute time trial, quadriceps low-frequency fatigue, creatine kinase levels, and subjective assessments of fatigue, recovery, and muscle soreness.
Key Findings
The results indicated that ISPC provided benefits in terms of subjective perceptions of recovery, muscle soreness, and fatigue. Specifically, improvements were noted in low-frequency fatigue scores and maximal voluntary contraction of knee extension (P < .05). However, these positive effects did not translate into enhanced performance during subsequent time trials conducted 24 hours later (P = .18). Additionally, no significant increase in creatine kinase activity was observed following the fatigue protocol, suggesting that the physiological impact of ISPC may not be as pronounced as its perceptual benefits.
In conclusion, while ISPC appears to enhance acute subjective and neuromuscular recovery markers following a strenuous cycling effort, it does not confer a performance advantage in short-duration cycling tasks conducted 24 hours post-intervention. Nevertheless, its application may still be justified for accelerating perceptual and neuromuscular recovery in high-level cyclists.
What this study does not show
This study does not demonstrate that ISPC improves performance outcomes in subsequent cycling trials, indicating that while recovery perceptions may improve, actual performance metrics do not necessarily follow suit.
