COLD-WATER IMMERSION IN THE RECOVERY OF IMMUNOINFLAMMATORY, FUNCTIONAL AND NEUROMUSCULAR MARKERS AFTER MUSCULAR DAMAGE
Cold-Water Immersion, muscle damage, crossfit
Cold-Water Immersion (CWI) is widely used in sports recovery. Changes in muscle damage markers can improve athletes' performance. However, the effects of CWI are still controversial. Objective: To analyze the effects of CWI in the recovery of clinical, immunoinflammatory, functional and neuromuscular markers of muscle damage in CrossFit practitioners. METHODS: This is a randomized, blind trial where CrossFit practitioners will be randomly assigned, after induced damage protocol, into 4 recovery groups (Control, Immersion, CWI and Ice Packs). They will be evaluated: subjective pain perception (VAS), Total Recovery Quality Scale (TQR), immunoinflammatory markers, triple jump unipodal, jump with counter movement and isokinetic dynamometry; pre, post-protocol damage, and after intervention (immediately after, 24h and 48h). Descriptive statistics followed by the Kolmogorov-Smirnov and Levene test. Subsequently, parametric or non-parametric tests will be used. Results will be considered with p value <0.05. Expected Results: CWI is expected to aid in the return of markers to pre-protocol conditions, without impairing the performance of athletes
