The effect of rehydration on anaerobic power and cardiac function in male club wrestler

Because of the little understanding about both cardiac function and also physical performance recovery in between the time period among formal wrestling weighing and the first competition following acute weight loss, in this research the efficiency of rehydration on anaerobic power, cardiac function and also Hct and plasma Aldosteron level’s recovery was evaluated similar to wrestling official weighing condition. 6.32 cm, weight: ± 36 elite male free style wrestlers (height: 174.33 3.83 year) voluntarily participated in this study. The ±15.26 kg and age: 22.66±79.53 group was then divided into two (experimental and control) groups for the present study which was conducted for 2 consecutive days. The cardio screen, blood sampling and RAST tests were taken respectively following a standard breakfast (after night fasting) at the first day morning (basal condition). Thereafter, dehydration 0.27% of body weight) was induced using sauna method in between 12 to 16 ±(1.48 pm and the cardio screen and blood sampling were repeated in the following. Finally, rehydration conducted until 24 pm. The second day morning was completely similar to the first one. The plasma Aldosteron and Hct levels measured using Elisa and Microhematocrit methods respectively. ANOVA for repeated measurements and pair samples t test was used to analyze the data at significance level equal to 0.05. There were not significant differences in between the first and second day’s anaerobic power indices (peak, min and mean power). Significant differences was observed only in experimental group with regard to all the measured variables [including stroke volume (SV), heart rate (HR), left cardiac work (LCW), rate pressure produce (RPP), systolic and diastolic blood pressure (SBP and DBP), left cardiac ejection time (LCET) and also Hct and Aldosteron levels] in between both dehydration rather than normal level and also rehydration rather than dehydration, in exception for the pre ejection period (PEP) and cardiac out put (P<0.05). The cardiac function is affected by acute dehydration; however it is not the case for anaerobic power. The induced changes can be defaulted by rehydration in between the official weighing and the first competition which indicates on poor prevention context toward acute body weight loss.
