Abstract
Purpose: The purpose of this study was to explore the effects of Cold Water Immersion (CWI) on markers of recovery, core temperature (Tc) and subsequent performance when used between high-intensity running bouts occurring on the same day. It was hypothesized that the use of cold water immersion would allow subjects to minimize the decrease in time to fatigue for the second test and result in lower blood lactate, core temperature and heart rate measures during and immediately post-exercise. Methods: The study followed a semi-randomized crossover design. Eight healthy males were recruited and for the purpose of data analysis, the males were separated into a group of 4 trained runners (RUN) and a group of 4 physically active individuals (PA) who regularly participated in an activity other than running. Subjects were required to schedule 3 separate days to complete testing. One visit was used to assess VO2 max and the other visits were trials of CWI (15 minutes to the depth of mid-femur) or control condition (passive standing). The visits were scheduled 7-10 days apart. Both experimental trials were comprised of 2 exercise tests on the treadmill at 90% VO2 max until volitional exhaustion separated by a recovery period of 3 hours. Tc measures were taken pre-exercise, immediately post-exercise, and post recovery period for all exercise tests completed. Blood Lactate (Bla) measures were taken immediately post-exercise, and 5, 10 and 15 minutes post-exercise for each exercise test. Running Economy was assessed during a 7-minute warm-up performed at 70% VO2 max prior to all exercise tests. Results: There were no significant differences in the measures obtained during CWI and control trials including time to exhaustion, Bla, Tc, HR, or running economy. Conclusion: Although CWI is often used in athletics to optimize recovery, supposed benefits of improved performance and accelerated recovery are not supported by this study. It appears as though CWI has no meaningful benefit based on the data obtained.
