Description
Summary: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 the training session.The results indicated no significant changes in the hydration status. Sprint time performance indicated no significant difference between all sets involved, indicating steady state sprint performance. Blood pressure, heart rate response and RPE, showed a significant increase during the 30m sprint training. Correlation value for sprint time and RPE versus hydration status demonstrated a significant correlation, a strong and linear relationship with a high significant value. As a conclusion, 30m RSA for 3 sets of 5 repetitions had no significant effect on hydration status, with sprint time performance cannot be said is influenced by hydration during RSA session. However, as the participants were trying to maintain sprint time performance, physical stress did increase and thus making it difficult to improve sprint time performance. The practical implications of this study suggested that apart from RSA actual purpose of developing speed and agility, it also offers an effective training practice for improving the heart rate responses and as anti-hypertensive exercise. Further studies on muscle metabolic factors are suggested for future research works.
