The purpose of this study was to investigate the influence of physical training on subjective vertical perception with the different head positions in order to explore the involving of the neck proprioception. Visual field dependence was assessed using a rod and frame test on women practising judo or dance (international level) or no specific physical(More)
The aim of the present work was to characterize the modifications of the postural adjustments during a climbing task as a function of postural and/or movement constraints. The variations of the horizontal and vertical forces and momentum were analyzed for different movement amplitudes and types of holds. The results show that the horizontal momentum is(More)
The aim of this study was to determine a predictive equation of 1 repetition maximum (1RM) from local muscular endurance. Different athletic male populations were assessed: racket/ball games players (n = 31), power lifters (n = 22), swimmers (n = 28), and rowers (n = 29). After the 1RM assessment for the bench press, the maximum number of repetitions (MNR)(More)
The aim of this study was to characterize the modifications of the posturo-kinetic coordination during a climbing task as a function of postural and/or movement constraints in children (8-10 years) and adolescents (10-15 years). A 3D-analysis of forces was recorded for different movement amplitudes and types of holds. The results show the involvement of(More)
The aim of this study was to investigate how the rating of perceived exertion (RPE) during resistance exercises was influenced by the exercise volume and athletes' training state. Eighty physical education students (well trained, less well trained, and novices) rated their perceived exertion of multilift sets using the category-ratio scale. These sets were(More)
The study investigated blood markers allowing discriminating physiological responses to on-water rowing races, notably regarding training volume of athletes and race duration. College (COL) and national (NAT) rowers performed a 1000- or 2000-m race. Capillary blood samples obtained before and post-race allowed an analysis of a wide range of serum(More)
Authors describe a new method to determine Mg2+ and Na+K+ATPase activity on extremely small samples of tissue homogenates. They use specific inhibitors to discern between the two activities and a sensitive colorimetric method to dose Pi released from ATP, Lower limit of sensitivity is about 0,0100 micromoles of Pi/mg proteins/hour.
The behaviour of some cardiovascular and metabolic parameters have been studied in 11 competitive road-cyclists under controlled submaximal work load. The test used was intermittent with load increasing from 100 to 250 watt, independent from age and body weight of the athletes. The results obtained have shown that whereas the estimated VO2 was 4,76 LO2/min,(More)
The efficient performance of voluntary movements requires a precise coordination between posture and movement. Anticipatory postural adjustments are believed to minimize the perturbation of balance triggered by the movement. This is particularly important in rock climbing where the unstable posture requires a fine balance control to preserve equilibrium.(More)
