The aim of this study was to investigate the relationship among hydration status level, sprint time performance capabilities and selected physiological responses which are blood pressure, heart rate and rate of perceived exertion (RPE) during a 30m Repeated Sprint Ability (RSA) training session. Fifteen male participants with mean age 21 ± 1 years old, total mean body weight of 63.21 ± 8.25kg, and mean body height of 1.68 ± 0.05m, voluntarily participated in this study. The participants underwent a RSA session with all measurements of interest (hydration status, sprint time performance, blood pressure, heart rate and RPE) were done pre, during and post sessions. Paired sample t-test was used to analyse the urine specific gravity, whilst repeated measure ANOVA was used to compare the sprint time, heart rate, blood pressure and RPE. Pearson correlation was utilised to determine the relationship between hydration status, sprint time, heart rate response, blood pressure and RPE during t.....
