Silva R, Cleto L, do Valle N, Gripp F, Rocha-Vieira E, Pinto K. Effect of Water Immersion on Post-Exercise Recovery from a Single Bout of Aerobic Exercise. JEPonline 2011;14(6):47-53. This study evaluated the effect of water immersion on physiological parameters at post-exercise recovery. Four male volunteers (26 ± 3.93 yr; VO2 peak 52.12 ± 9.07 mL?kg?min-1 ) underwent a unilateral eccentric knee extension followed by 30 min of treadmill exercise at 70% of VO2 peak. Immediately after, they were subjected to three different protocols of water immersion, for 15 min: cold-water immersion (CWI), hot-water immersion (HWI), and intermediate-water immersion (IWI). Control group remained seated on bath tube with no water for 15 min. Protocols were conducted in a cross-over balanced way with 7 days of interval between tests. Heart rate (HR), body temperature, and serum lactate levels were monitored during exercise and recovery and excess post-exercise oxygen consumption (EPOC) measured during recovery. Body temperature was reduced during CWI and HR was increased during both CWI and HWI. However, no effect of water immersion was observed on lactate levels and EPOC. The findings indicate that water immersion affects the recovery of some physiological parameters following exercise, but not all. How this modified physiological response influences exercise performance is under investigation.
