Over the past few years, competitive rock climbing has experienced increased popularity world wide. In 1989, the first six-event World Cup competition was held with all events contested on artificial modular walls. The aim of this study was to determine the extent to which oxidative metabolism is utilized in competitive rock climbing with regard to the(More)
PURPOSE This study compares the physical and training characteristics of top-class marathon runners (TC), i.e., runners having a personal best of less than 2 h 11 min for males and 2 h 32 min for females, respectively, versus high-level (HL) (< 2 h 16 min and < 2 h 38 min). METHODS Twenty marathon runners (five TC and HL in each gender) ran 10 km at their(More)
Interval training consisting of brief high intensity repetitive runs (30 s) alternating with periods of complete rest (30 s) has been reported to be efficient in improving maximal oxygen uptake (V˙O2max) and to be tolerated well even by untrained persons. However, these studies have not investigated the effects of the time spent at V˙O2max which could be an(More)
PURPOSE Between inefficient training and overtraining, an appropriate training stimulus (in terms of intensity and duration) has to be determined in accordance with individual capacities. Interval training at the minimal velocity associated with VO2max (vVO2max) allows an athlete to run for as long as possible at VO2max. Nevertheless, we don't know the(More)
PURPOSE This study compares the training characteristics and the physical profiles of top-class male and female Kenyan long-distance runners. METHOD The subjects were 20 elite Kenyan runners: 13 men (10-km performance time: 10-km performance time of 28 min, 36 s +/- 18 s) and 7 women (32 min, 32 s +/- 65 s). The male runners were separated into high-speed(More)
The so-called velocity associated with V˙O2max, defined as the minimal velocity which elicits V˙O2max in an incremental exercise protocol (v V˙ O2max), is currently used for training to improve V˙O2max. However, it is well known that it is not the sole velocity which elicits V˙O2max and it is possible to achieve V˙O2max at velocities lower and higher than v(More)
The aim of this study was to measure running times to exhaustion (Tlim) on a treadmill at 100% of the minimum velocity which elicits VO2max (vVO2max in 38 elite male long-distance runners (VO2max = 71.4 +/- 5.5 ml.kg-1.min-1 and vVO2max = 21.8 +/- 1.2 km.h-1). The lactate threshold (LT) was defined as a starting point of accelerated lactate accumulation(More)
This study investigates whether a 6-wk intermittent hypoxia training (IHT), designed to avoid reductions in training loads and intensities, improves the endurance performance capacity of competitive distance runners. Eighteen athletes were randomly assigned to train in normoxia [Nor group; n = 9; maximal oxygen uptake (VO2 max) = 61.5 +/- 1.1 ml x kg(-1) x(More)
The purpose of this study was to assess the reproducibility of running time to exhaustion (Tlim) at maximal aerobic speed (MAS: the minimum speed that elicits VO2max), on eight subelite male long distance runners (29 +/- 3-yr-old; VO2max = 69.5 +/- 4.2 ml.kg-1.min-1; MAS = 21.25 +/- 1.1 km.h-1). No significant differences were observed between Tlim measured(More)
The maximal lactate steady state (MLSS) is defined as the highest blood lactate concentration (MLSSc) and work load (MLSSw) that can be maintained over time without a continual blood lactate accumulation. A close relationship between endurance sport performance and MLSSw has been reported and the average velocity over a marathon is just below MLSSw. This(More)
