Estimating Contributions of Cold Water Immersion to Recovery from Exercise
Abstract
Investigate the efficacy of cold water immersion (CWI) for alleviating perceived soreness and to estimate its contributions to muscle damage recovery after exercise. METHODS: Fourteen (mean age=22.4 years, height= 1.81m, mass=88.38kg) males with history of resistance training (defined by at participation in 3 resistance training sessions a week) visited the lab on 2 occasions, separated by 7 days. First visit involved familiarization protocol with the Biodex 3 dynamometer. Participants performed isometric maximal voluntary contractions (MVCs) at a fixed joint angle of 120� to determine peak torque of the knee extensors before the exercise protocol (PRE), immediate post-exercise protocol (IPP), immediate post-treatment (IPT), and fifteen minutes post-treatment (15minPost, treatment visit only). The eccentric exercise protocol (10 repetitions/set at 60�/s) designed to induce muscle damage was performed on right leg only during treatment and control visit (randomized visits). Control involved sitting quietly in a chair in the research laboratory for 10 minutes. The treatment condition involved CWI up to the iliac crest in 10�C (50�F) water for 5 minutes. Perceived soreness was measured using 100-point analog scale. Soreness was measured during both visits at 5 time points (PRE, IPP, IPT, 24HrPost, 48HrPost). Separate 2-way mixed factorial ANOVAs were performed for each dependent variable. An alpha level of p?0.05 was utilized to determine statistical significance. RESULTS: Significant visit x time interaction found for exercise leg MVC torque [F(2,26)=3.463, p=0.046]. MVC torque IPT treatment significantly lower than PRE treatment [p=0.045]. Significant effect for time found for MVC during treatment visit exercise leg [F(2,26)=4.471, p=0.021]. Significant interaction found between condition and time for exercise leg treatment visit MVC [F(2,26)= 3.463, p=0.046]. There was no significant visit x time interaction for control leg MVC [F(2,26)=1.086, p=0.352]. No significant main effect for time of control leg MVC [F(2,26)= 0.871, p=0.430]. A significant main effect for condition was found for control leg MVC [F(1,13)=6.401, p=0.025]. Significant difference found between control and treatment visit perceived soreness at 24HrPost for exercise leg [p=0.028]. CONCLUSIONS: CWI did not have an effect on peak torque production, but significantly reduced perceived soreness 24HrPost treatment on the exercise leg compared to control visit.
