This study investigated fluid and electrolyte balance in well-trained male and female swimmers during 2 training sessions. Participants were 17 nationally ranked swimmers measured during a period of intensive training. Sweat loss was assessed from changes in body mass after correction for fluid intake and urine collection. Sweat composition was measured from waterproof absorbent patches applied...

BACKGROUND Previous research has shown that cognitive and motor skills are related. The precise impact of cognitive impairment on sport proficiency, however, is unknown. AIMS This study investigated group and individual differences in cognitive profiles in a large cohort of track and field athletes, basketball players, swimmers and table tennis players with (N=468) and without (N=162) intelle...

Increased plasma nitrate concentrations from dietary sources of nitrate have proven to benefit exercise performance. Beetroot (BR) contains relatively high levels of nitrate (NO₃⁻), which increases nitric oxide stores. This study investigated whether dietary nitrate supplementation, in the form of a BR beverage, would improve rowing performance during ergometer repetitions. In a randomized cros...

This paper proposes a new framework to simulate the real-time attack-and-defense interactions by two virtual wrestlers in 3D computer games. The characters are controlled individually by two different players—one player controls the attacker and the other controls the defender. A finite state machine of attacks and defenses based on topology coordinates is precomputed and used to control the vi...

Amateur wrestling at the high school and collegiate level in the United States often involves exercise and thermal dehydration as well as food and fluid restriction to "make weight". Available evidence suggests this is the opposite of what is optimal for high-intensity exercise performance. A high-intensity taper will substantially improve performance when conducted after a period of high-volum...

OBJECTIVE: To investigate the reliability and validity of refractometry, hydrometry, and reagent strips in assessing urine specific gravity in collegiate wrestlers. DESIGN AND SETTING: We assessed the reliability of refractometry, hydrometry, and reagent strips between 2 trials and among 4 testers. The validity of hydrometry and reagent strips was assessed by comparison with refractometry, the ...
