This randomized crossover trial examined immediate responses to intermittent cold compression (ICC) after a soccer-specific fatigue protocol in seven male collegiate soccer players. Participants received a single 20-minute intervention at 1°C using either low pressure (5-15 mmHg) or moderate pressure (5-50 mmHg). Pain and perceived exertion decreased after treatment, without significant differences by pressure. Countermovement jump height, peak force, and peak power declined post-intervention. Pressure-by-time interactions were observed for rate of force development and lateral gastrocnemius logarithmic decrement, although there were no significant within-condition changes in rate of force development.
Key findings
- Pain and perceived exertion decreased from pre- to post-intervention (p < 0.05), with no significant pressure or pressure × time effects.
- Countermovement jump height, peak force, and peak power all declined post-intervention, with significant time effects.
- Pressure × time interactions were found for rate of force development (F = 6.07, p = 0.049, η2ₚ = 0.503) and lateral gastrocnemius logarithmic decrement (F = 9.21, p = 0.023, η2ₚ = 0.606).
Why it matters
The findings distinguish subjective symptom relief from immediate functional recovery: players reported less pain and exertion, while several jump-performance measures declined. The pressure-related interactions suggest that ICC pressure may affect some acute neuromuscular and muscle-mechanical responses, but the results do not establish which pressure is preferable or whether these changes translate into meaningful recovery.
What to keep in mind
The trial included only seven players and assessed immediate responses after a single intervention. The authors also note that there were no significant within-condition changes in rate of force development.
