The Changes of Some Electrolytes after Two Months Activity
- 1 ,
Some investigators have speculated that sodium chloride losses in sweat associated with net dehydration may lead to the observed hyponatremia after prolong strenuous exercise. The effects of altered hydration can influence athletes cognitively in addition to physically. In this research, rest alterations of sodium and potassium of blood serum have been investigated. The subjects were male students who have been selected purposefully. Variables of height, weight, age and body mass index (BMI) have been measured too. Participants took part in the training of incremental continuous running for 2 times in a week for 2 months. The running distance for subjects had been planned before performing main protocol training. The heart rate was controlled by polar watches. In the first and last session of training, the subjects’' oxygen consumption (VO2 max) was measured. The data analysis by means of paired sample t-test showed that: 1. The subjects' sodium of serum had an increase of 2.21 mEq/L-1 even after 24 h. Its reason can be due to the loss of water and body fluids in the final session of training.2. The subjects' potassium of rest serum had an increase of 0.13 m Eq L-1 that probably the extra- cellular potassium had returned into the intracellular. The observation suggested that accumulation of extra cellular potassium might be important for the development of fatigue in human muscles. We concluded that sodium of serum had an increased after 24 h. Its reason can be due to the loss of water and body fluids in the final session of training. The subjects' potassium of rest serum had an increased that probably the extra-cellular potassium had returned into the intracellular. Also, this research recommends athletes must be used as dietary supplements in products designed to affect physical performance (ergogenic aids), their use should be considered.
