EFFECTS OF VOLUNTARY FLUID INTAKE DEPRIVATION ON MENTAL AND PSYCHOMOTOR PERFORMANCE
AIM: To assess if there is deterioration in mental and psychomotor performance during 24-hour voluntary fluid intake deprivation. METHODS: A battery of computer generated psychological tests (Complex Reactionmeter Drenovac-series) was applied to 10 subjects to test light signal position discrimination, short-term memory, simple visual orientation, simple arithmetics, and complex motor coordination. We measured total test [...]
HYPERTHERMIA AND DEHYDRATION-RELATED DEATHS ASSOCIATED WITH INTENTIONAL RAPID WEIGHT LOSS IN THREE COLLEGIATE WRESTLERSA—NORTH CAROLINA, WISCONSIN, AND MICHIGAN, NOVEMBERA–DECEMBER 1997
Centers for Disease Control and Prevention (CDC). During November 7-December 9, 1997, three previously healthy collegiate wrestlers in different states died while each was engaged in a program of rapid weight loss to qualify for competition. In the hours preceding the official weigh-in, all three wrestlers engaged in a similar rapid weight-loss regimen that promoted [...]
A review of fluid and hydration in competitive tennis.
Hypohydration is known to impair performance and increases the risk of heat injury. Therefore, the consumption of appropriate fluid volumes before, during, and after tennis play is important to maintain physiological homeostasis and performance. Tennis is a sport that typically has points lasting fewer than ten seconds, with short-to-moderate rest periods between each work bout. [...]
Hydration status in college football players during consecutive days of twice-a-day preseason practices.
BACKGROUND: Football players lose 3.5 to 5 kg of body weight during preseason practices because of heavy sweating. This fluid may be difficult to replace when practices occur 2 times per day on consecutive days. HYPOTHESIS: Football players are hypohydrated during twice-a-day preseason training in a hot, humid environment. STUDY DESIGN: Descriptive laboratory study. METHODS: [...]
Hydration and muscular performance: does fluid balance affect strength, power and high-intensity endurance?
Significant scientific evidence documents the deleterious effects of hypohydration (reduced total body water) on endurance exercise performance; however, the influence of hypohydration on muscular strength, power and high-intensity endurance (maximal activities lasting >30 seconds but
Nutrition and hydration concerns of the female football player.
There is little information on the nutritional habits of female football players at any level of the game. There is also a shortage of information on the nutrition and hydration strategies that players should adopt. In general, differences in nutritional needs between males and females are smaller than differences between individuals, so that principles developed [...]
Effects of hydration state and resistance exercise on markers of muscle damage.
It is well established that resistance exercise can damage muscle tissue, but the combined effects of hypohydration and resistance exercise on muscle damage are unclear. Two common circulating markers of muscle damage, myoglobin (Mb) and creatine kinase (CK) may be attenuated by fluid ingestion post-exercise. The purpose of this study was to examine the combined [...]
Effect of hydration state on testosterone and cortisol responses to training-intensity exercise in collegiate runners.
Exercise intensity powerfully influences testosterone, cortisol, and testosterone : cortisol ratio (T:C) responses to endurance exercise. Hydration state may also modulate these hormones, and therefore may alter the anabolic/catabolic balance in response to endurance exercise and training. This study examined the effect of running intensity on testosterone, cortisol, and T : C when exercise was [...]
