Trial Outcomes & Findings for The Effect of Thermotherapy on Recovery and Performance (NCT NCT02506283)
NCT ID: NCT02506283
Last Updated: 2025-10-17
Results Overview
The subjective recovery characteristics "Delayed-onset muscle soreness (DOMS)" was rated on a 0-10 cm visual analog scale. DOMS was assessed in a squat position (90° knee angle, with brief holding of maximum 3 seconds) ranging from zero (no soreness) to ten (severe soreness). Higher values mean mean more DOMS and therefore less recovery.

PRIMARY outcome
Timeframe: 72 hoursThe subjective recovery characteristics " Ratings of perceived exertion (RPE)" was rated on a 6-20 Borg scale (from 6 = "no exertion at all" to 20 = "Maximal exertion") in a standing position. The higher value means more exertion and therefore less recovery.

PRIMARY outcome
Timeframe: 72 hoursVertical jump performance (VJP) was assessed performing three maximal counter mouvemet jumps (CMJs) with a 30-second pause between the three jumps on the Just Jump system (Probotics Inc, Huntsville, AL, USA). The highest jump was recorded.

PRIMARY outcome
Timeframe: 72 hoursPeak power output (PPO) was assessed performing three maximal counter movement jumps (CMJs) on the Just Jump system (Probotics Inc, Huntsville, AL, USA) with a 30-second pause between the three jumps. PPO (presented in watts) was calculated.
