Relationship between creatine kinase activity and muscle damage induced by running following cold-water immersion in 10-km runners: secondary analysis of randomized controlled trial

Abstract

10-km street run is a highly popular and accessible sport, yet can result in exercise-induced muscle damage for runners. Ensuring a positive continuation of sports practice after the recovery process from running performance becomes essential. While several therapeutics modalities have been employed for accelerate performance recovery, Cold-Water Immersion (CWI) notably stands out among them. In addition, although Creatine Kinase concentration ([CK]) has been used to monitor the recovery status, its relationship with other muscle damage indirect markers following exercise remains inconclusive. Thus, this study aimed to investigate the relationships between creatine kinase concentration ([CK]) and pain, and functional and neuromuscular muscle damage markers after a 10-km street run following cold-water immersion (CWI).
