Abstract

The research aims to identify the effect of taking metered doses of fluids and salts during aerobic physical performance in hot, humid air at: 1 - the level of aldosterone, angiotensin II, sodium and potassium in the blood. 2 - some health variables (body temperature, skin temperature) , Al-Jouf temperature, pulse rate, and arterial blood pressure. The researcher used the experimental approach to design the measurement (tribal - dimensional) on two groups, one of which is control and the other is experimental, as it suits the nature and objectives of this study. Sports in a governorate Giza in the Sunni phase of (19-20) years, and registered in the Egyptian Football Association season (2016/2017), and they are (35) football players, randomly selected (3) players for exploratory study, and (32) players for the two research groups were distributed randomly
Conclusions: 1- The administration of controlled doses of liquids and salts during aerobic physical performance in the hot atmosphere positively affects the biochemical variables of the experimental group compared to the control group with an improvement rate of (4.58%), for the hormone aldosterone, and (18.87%), for angiotensin II, and (5.44). %), For sodium, and (25.75%) for potassium. 2- The administration of standardized doses of fluids and salts during aerobic physical performance in hot weather positively affects the health variables of the experimental group compared to the control group with an improvement rate of (2.37 %% (body temperature, and) 2.28 %%) skin temperature, (1.26%), cavity temperature, and (1.44 %%) pulping rate Z, (9.00 %%) for systolic blood pressure, and (10.70%) for diastolic blood pressure.
