Prolonged cooling with phase change material enhances recovery and does not affect the subsequent repeated bout effect following exercise

The aim of this investigation was twofold: (1) to examine the effect of prolonged phase change material (PCM) cooling following eccentric exercise of the quadriceps on indices of muscle damage, and (2) to elucidate whether application of PCM cooling blunted the acute adaptive response to eccentric exercise, known as the repeated bout effect (RBE). Twenty-six males (25 ± 6 years) performed an initial bout (B1) of 120 eccentric quadriceps...
