The prevalence of exercise-associated hyponatremia in 24-hour ultra-mountain bikers, 24-hour ultra-runners and multi-stage ultra-mountain bikers in the Czech Republic
BACKGROUND To assess the prevalence of exercise-associated hyponatremia (EAH) in two 24-hour mountain bike (MTB) (R1,R2), one 24-hour running (R3) and one multi-stage MTB (R4) races held in the Czech Republic in a cluster of four cross-sectional studies. METHODS In 27 ultra-mountain bikers (ultra-MTBers), 12 ultra-runners, and 14 multi-stage MTBers, fluid intake, changes (Δ) in body mass, hem...
متن کاملDo non-elite older runners slow down more than younger runners in a 100 km ultra-marathon?
BACKGROUND This study investigated changes in normalised running speed as a proxy for effort distribution over segments in male elite and age group 100 km ultra-marathoners with the assumption that older runners would slow down more than younger runners. METHODS The annual ten fastest finishers (i.e. elite and age group runners) competing between 2000 and 2009 in the '100 km Lauf Biel' were i...
متن کاملNo association of skin-fold thicknesses and training with race performance in male ultra-endurance runners in a 24-hour run
Knechtle B, Knechtle P, Rosemann T. No association of skin-fold thicknesses and training with race performance in male ultra-endurance runners in a 24-hour run. J. Hum. Sport Exerc. Vol. 6, No. 1, pp. 94100, 2011. In male high-level long-distance runners over 10,000 m, a positive association between both the front thigh and medial calf skin-fold thickness and running performance has been demons...
متن کاملChanges in blood morphology and chosen biochemical parameters in ultra-marathon runners during a 100-km run in relation to the age and speed of runners.
OBJECTIVES The objective of the study was to reveal morphology, electrolyte and chosen biochemical parameters in terms of health risk in runners in reference to their age and running speed in the case of running a distance of 100 km, which occur after 12 h or 24 h of recovery. MATERIAL AND METHODS Fourteen experienced, male, amateur, ultra-marathon runners, divided into two age and two speed ...
متن کامل24-h Fluid Kinetics and Perception of Sweat Losses Following a 1-h Run in a Temperate Environment
This study examined 24-h post-run hydration status and sweat loss estimation accuracy in college age runners (men=12, women=8) after completing a 1-h self-paced outdoor run (wet bulb globe temperature=19.9±3.0 °C). Sweat losses (1353±422 mL; 1.9%±0.5% of body mass) were significantly greater (p<0.001) than perceived losses (686±586 mL). Cumulative fluid consumption equaled 3876±1133 mL (218±178...
