Comparison of water turnover rates in young swimmers in training and age-matched non-training individuals

Article Abstract:

The primary aim of the present study was to use deuterium oxide as a tracer for water to examine the relative rates of daily water turnover in a group of competitive swimmers and a group of age-matched control subjects who did no specific training. The results from the study show that the water turnover in young swimmers training in cool water is faster than that of age-matched non-training individuals due to the approximately three times greater non-renal water losses that the swimming group incurred.

Gastric emptying of fluids during variable-intensity running in the heat

Article Abstract:

Gastric emptying, core temperature and sprint performance are examined during prolonged intermittent shuttle running in 30 [degree] C when ingesting a carbohydrate-electrolyte solution (CES) or flavored water (FW). The results have shown that sprint performance is increased by the ingestion of a CES, which has resulted in elevated core temperatures, and the rate of gastric emptying has remained similar between solutions.

Effect of iron injections on aerobic-exercise performance of iron depleted female athletes

Article Abstract:

The effect of intramuscular iron injections on aerobic-exercise performance in iron-deficient female athletes is investigated. The results have shown that intramuscular iron injections have increased iron-supplemented group's (IG's) serum ferritin (SF) without increasing submaximal or maximal aerobic-exercise performance in iron-depleted female athletes.
