Abstract
Purpose: To examine the effect of post-exercise cold water immersion (CWI) protocols compared with control (CON), on the magnitude and time-course of core temperature (Tc) responses. Methods: Pooled data analyses were used to examine the Tc responses of 157 subjects from previous post-exercise CWI trials in our laboratories. CWI protocols varied with different combinations of temperature, duration, immersion depth and mode (continuous vs intermittent). Tc was examined as a double difference (ΔΔTc), calculated as the change in Tc in CWI condition minus the corresponding change in CON. The effect of CWI on ΔΔTc was assessed using separate linear mixed models across two time components (Component 1: immersion, and Component 2: post-intervention). Results: Intermittent CWI resulted in a mean decrease in ΔΔTc that was 0.254±0.10°C (estimate±SE) greater than continuous CWI during the immersion component (P=0.022). There was a significant effect of CWI temperature during the immersion component (P=0.050), where reductions in water temperature of 1°C resulted in decreases in ΔΔTc of 0.03±0.01°C. Similarly, the effect of CWI duration was significant during the immersion component (P=0.01), where every 1 min of immersion resulted in a decrease in ΔΔTc of 0.02±0.01°C. The peak difference in Tc between the CWI and CON interventions during the post-immersion component occurred at 60 min post-intervention. Conclusion: Variations in CWI mode, duration and temperature, may have a significant effect on the extent of change in Tc. Careful consideration should be given to determine the optimal amount of core cooling before deciding which combination of protocol factors to prescribe.
