Abstract
The aim of this study was to examine heart rate, sweat rate and composition, as well as urinary volume, colour and osmolarity, during a single competitive cricket match and training session. Two sub-elite fast bowlers participated in this study. Subjects were measured under warm environmental conditions with wet bulb globe temperature indices of 22.9 and 19.5, respectively. Heart rate was recorded continuously throughout the match and the training session using Polar Vantage NV recordable heart rate monitors. Both players were weighed before and after each session of play and during competition and training. Absorbent patches collected sweat from the upper back and forearm. These remained in place for the duration of competition and training. Sweat was subsequently analysed for sodium (Na+) and potassium (K+) composition. Throughout the periods of data collection urine was collected and measured for volume, colour and subsequent osmolarity. The results from this study identify the inter-differences in both sweating response and drinking practices of the two fast bowlers, thus supporting the use of individualised hydration strategies.
