Recovery is important among athletes, especially after exercises and competitions. There are several different recovery methods. The most important of these are active recovery methods, like low-intensity aerobic exercise and mobility exercises. There are also passive recovery methods, like sleep, nutrition, massage, thermal methods and cold treatments. The aim of this study was to clarify the effectiveness of three water immersion interventions after active recovery in comparison to only active recovery on physical performance and physiological variables affecting it.\r\nMethods. The subjects were physically active men (age 20-35 years, n = 9). All volunteers performed an intensive exercise, which included jumping and sprinting (total duration 45 minutes). Four different recovery methods (10 minutes) were used in random order: cold water immersion (CWI, 10 \u1d52C), thermoneutral water immersion (TWI, 24 \u1d52C), contrast water therapy (CWT, alternately 10 \u1d52C and 38 \u1d52C), all of which was performed after an active recovery (10 minutes bicycle ergometer), and the fourth method was just the active recovery (ACT). Recovery was evaluated during 96 hours with a 30 m running test, a maximal counter-movement-jump, self-perceived muscle soreness and relaxation questionnares , blood lactate, pH, creatine kinase (CK), myoglobin, high-sensitive C-reactive protein (CRP), testosterone, cortisol and catecholamine levels. The variance analysis of repeated measurements and non-parametric Friedman and Wilcoxon tests were used in the statistical analysis of the results. The correlations between the variables were analysed using Pearson and Spearman correlation tests. The limit of the statistical significance was p < 0.05.\r\nResults. The self-perceived feeling of relaxation after one hour recovery was better after CWI and CWT than the active recovery and TWI, respectively. In performance measurements (a 30 m running test and a counter-movement-jump), self-perceived muscle soreness, blood lactate, pH, CK, myoglobin, and high-sensitive CRP levels, no statistically significant differences were found between the recovery methods.\r\nHowever, there were indications that the individual performance benefit may be possible when the results were compared to baseline within the recovery method. Especially CWI and TWI could improve the recovery of power and speed capacities in some individuals. In addition, after TWI faster recovery of lactate concentration was observed in some subjects when the results were compared to baseline values within the recovery method.\r\nFor a longer period recovery (at 48 h), a higher serum cortisol content was observed after TWI compared to the active recovery values. Also, after all the water immersion methods the serum testosterone concentration was found to be statistically significantly lower than baseline after one hour recovery, when the values were compared the baseline values within the recovery method. In addition, after CWI higher adrenaline and noradrenaline levels were observed after 40 minutes recovery when the results were analysed within recovery procedures.\r\nDiscussion. Based on this study, it can be concluded that CWI (10 \u1d52C) and CWT (alternately 10 \u1d52C and 38 \u1d52C) improve the acute feeling of relaxation that can play a positive role in athletes' performance and well-being. Furthermore, in some individuals, the recovery of power and speed capacities can be improved by using water immersion methods. Additionally, hormonal measurements suggest that in a longer period recovery water immersion methods can attenuate individual recovery of the body. Increased elevated cortisol levels, decreased testosterone concentrations and increased adrenaline and noradrenaline levels can, for example, increase the stress of the body and impair both protein synthesis and energy metabolism.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Raila Salminen (rsalmine) on 2017-12-15 13:13:06.267334.
