Abstract
Purpose: To evaluate the effectiveness between cold water immersion (CWI) and phase change material (PCM) cooling on intramuscular, core and skin temperature and cardiovascular responses. Methods: In a randomized, crossover design, 11 males completed 15 min of 15°C CWI to the umbilicus and 2 h recovery or 3 h of 15°C PCM covering the quadriceps and 1 h of recovery, separated by 24 h. Vastus lateralis intramuscular temperature at 1 and 3 cm, core and skin temperature, heart rate variability and thermal comfort were recorded at baseline, and 15 min intervals throughout treatment and recovery. Results: Intramuscular temperature decreased (P
