Influence of Body Hydration in Moderate Weather on Aerobic, Anaerobic Capacity and Fatigue Index in Athletes Girls

Previous studies have indicated that body hydration can influence some physiological functions. The aim of present study was evaluating influence of body hydration on aerobic and anaerobic power and fatigue index.
This research was a semi-experimental study that 30 female students (age: 21.92 ±1.14 years¡ height: 162.20± 6.00¡ weight: 59.3±10.32 kg) with at least 3 years regular sport activities voluntarily participated in this study. During three intermittent sessions subjects experienced three hydration status including dehydration (2-5 %) ¡ hydration and hyperhydration (3%). For evaluating aerobic and anaerobic power Incremental Bruce test and Rast test were used respectively. Data were analyzed by using repeated measures analysis of variance method.
Results of study indicated that dehydration changed significantly aerobic power ¡ but hyper hydration increased aerobic power significantly (P According to these findings¡ in order to improve aerobic¡ average and maximum anaerobic power¡ we can recommend athletes drink water enough to prevent dehydration before exercise.
