PURPOSE This study examined the validity of a squash-specific test designed to assess endurance capability and aerobic power. METHODS Eight squash players and eight runners performed, in a counterbalanced order, incremental treadmill (TT) and squash-specific (ST) tests to volitional exhaustion. Breath-by-breath oxygen uptake was determined by a portable analyzer and heart rate was assessed te...

Purpose. the association between anthropometric and training characteristics on an athlete’s performance has been investigated in swimmers, cyclists and runners, but not in inline skaters. the aim of this study was to investigate the relationship between anthropometry, pre race preparation and equipment in the finishers of the longest inline race in Europe, the ‘Inline One eleven’ over 111 km i...

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...

Both hyponatremia and osteopenia separately have been well documented in endurance athletes. Although bone has been shown to act as a "sodium reservoir" to buffer severe plasma sodium derangements in animals, recent data have suggested a similar function in humans. We aimed to explore if acute changes in bone mineral content were associated with changes in plasma sodium concentration in runners...

introduction exercise is associated with an increase in cortisol - the most important hormone in fat metabolism. cortisol levels vary during a day. this study was conducted in view of the lack of any documents on cortisol levels in endurance athletics in iran. methods in a cross-sectional study, 25 male endurance runners age 18-25 years and 25 non-athlete men were selected. the cortisole and tg...

BACKGROUND The performance in master marathoners has been investigated in flat city marathons but not in mountain marathons. This study examined changes in the sex differences in performance across time in female and male master runners competing in a mountain marathon compared to a flat city marathon. METHODS The association between age and performance of finishers in the Jungfrau Marathon, ...

AIMS We assessed the changes in cardiac morphology between elite endurance-trained runners (n = 42) and elite sprinters (n = 34) over a 5-year period. In addition, we studied the relationship between heart size and maximum oxygen consumption (VO2 max). METHODS At the beginning of 5 consecutive seasons, all athletes underwent an incremental running test to determine VO2 max and a color-coded p...
