Introduction La santé étudiante préoccupe de nombreux professionnels, chercheurs et institutionnels. Le rapport sur la santé des jeunes en 2013 met en évidence des comportements à risque importants chez les jeunes et jeunes adultes (Beck & Richard, 2013). L’inactivité physique fait partie des conduites à risque à un tel point que l’Organisation Mon...

The aim of this study was to determine whether an increase in O2 availability induces an alteration of the balance between O2 consumption ((V)O2) and O2 delivery ((Q)O2) at the muscle level. For that, we examined the effect of moderate hyperoxia on muscle deoxygenation kinetics at the onset of heavy-intensity cycling exercise. Eight young male adul...

This study examines the effect of prior heavy exercise on the spatial distribution of muscle deoxygenation kinetics at the onset of heavy-intensity cycling exercise. Young untrained male adults (n = 16) performed two consecutive bouts of 6 min of high intensity cycle exercise separated by 6 min at 35 W. Muscle deoxygenation (HHb) was monitored cont...

The first purpose of this study was to determine whether the peak velocity (V(Yo-Yo)) achieved during the Yo-Yo intermittent recovery test (Yo-Yo) and the maximal aerobic velocity (MAV) determined from the Université de Montréal Track Test (UMTT) could be used interchangeably. The second purpose was to check that the V(Yo-Yo) is related to the inte...

This study examines the effect of prior heavy exercise on muscle deoxygenation kinetics at the onset of heavy-intensity cycling exercise. Ten young male adults (20 +/- 2 years) performed two repetitions of step transitions (6 min) from 35 W to heavy-intensity exercise preceded by either no warm-up or by a heavy-intensity exercise. VO2 was measured...

To examine the effect of 6-week of high-intensity interval training (HIT) and of 6-week of detraining on the VO2/Work Rate (WR) relationship and on the slow component of VO2, nine young male adults performed on cycle ergometer, before, after training and after detraining, an incremental exercise (IE), and a 6-min constant work rate exercise (CWRE)...

This work aimed to investigate accessory respiratory muscle oxygenation (RMO(2)) during exercise, using near-infrared spectroscopy, and to study relationships between RMO(2) kinetics and breathing parameters. Nineteen young males (19.3 +/- 1.5 years) performed a maximal incremental test on a cycle ergometer. Changes in breathing pattern were charac...
Article
Full-text available
We investigated the potential effect of respiratory muscle work on leg muscle oxygenation without artificial intervention in non-endurance-trained young subjects and searched for the range of intensity when this effect could occur. We simultaneously monitored accessory respiratory and leg muscle oxygenation patterns with near-infrared spectroscopy...
Article

The aim of this experimentation was to study the effects of a combined training, in running and cycling on the cardiorespiratory responses during a progressive and exhaustive test on track. 16 male long-distance runners (26-34 years) of regional level have been compared before and after training. The subjects trained four times a week during eight...

The aim of this study was to investigate the development of exercise-induced hypoxemia (EIH defined as an exercise decrease > 4 % in oxygen arterial saturation, i. e. SaO (2) measured with a portable pulse oximeter) in twelve sportsmen and ten sportswomen (18.5 +/- 0.5 years) who were non-elite and not initially engaged in endurance sport or traini...

This study was designed to calculate the critical velocity (vcrit) and anaerobic distance capacity (ADC) of prepubescent children for running events. Thirty-four prepubertal children underwent a graded field test to exhaustion in order to determine peak oxygen uptake (peak VO2) and maximal aerobic velocity (MAV). Then, in random order, they perform...

The purpose of this study was to compare the effects of active vs. passive recovery on the time to exhaustion for intermittent runs (15 s) at supramaximal velocity (120% of maximal aerobic speed). Twelve male subjects performed a graded test, an intermittent run to exhaustion with active recovery (50% of maximal aerobic speed) and an intermittent r...
Article

This study was designed to propose a standardised procedure to determine the time spent at VO2max (tVO2max) based on the VO2max of the day (i. e. the VO2max value measured the day of the test). Ten male subjects first performed a graded field test, followed by a continuous running exercise to exhaustion, at the velocity of the Université de Montréa...
Article
Highly trained sportsmen and sportswomen in endurance may present exercise-induced hypoxemia (EIH). The aim of this investigation was to determine whether a 8 week interval training period may induced EIH in low trained athletes.Results – After training, in a population of 24 subjects, 7 presented a mild or moderate EIH, 7 presented a light EIH and...

This study was designed to examine peak VO(2) responses of prepubescent children following a 7-week aerobic training. Twenty-three boys and thirty girls (9.7 +/- 0.8 years) were divided into a high intensity experimental group (HIEG: 20 girls and 13 boys) and a control group (CG: 10 girls and 10 boys). A graded 20-m shuttle run with measurement of...

This study was designed to determine the intermittent critical velocity, the time spent at maximal oxygen uptake (VO2max) and the time spent above 90% of VO2max for short intermittent runs of 15 s at supramaximal velocities, alternating with 15 s of passive recovery. Nine male subjects performed 5 field-tests to exhaustion (tlim): 4 intermittent ru...

Introduction - The aim of this study was to examine peak VO2 responses of prepubescent children, after a 7-week aerobic training programme, which included intermittent bouts at maximal and supramaximal velocities. Method and results - Fifty three children divided into an experimental group (n = 33) and a control group (n = 20). Prior to and after t...

The aim of the present study was to explain the inter-individual variability in running time to exhaustion (tlim) when running speed was expressed as a percentage of the velocity, associated with maximal oxygen uptake (vVO2max). Indeed for the same percentage of vVO2max the anaerobic contribution to energy supply is different and could be dependent...

The velocity at VO2 max, signification and applications to running This review focuses on the concept of velocity at VO2 max. Thus velocity is related to aerobic performance and could be used as a criterion of velocity to set running paces for training. Two groups of protocols have been proposed to measure the velocity at VO2 max. The first types o...

Purpose When running speed is set as percentage of the velocity associated with maximal oxygen uptake, a great variability between individuals in time to exhaustion is observed. We hypothesis this could be explain by the fact that this intensity didn't represent the same for all. Methods and results Running time to exhaustion at 90%, 100%, 120% an...

Aim Try to predict world records in running over 200 meters and over marathon, distances representative of speed quality and human endurance, respectively. Methods and results We have then used a smoothing exponential model to predict world records from actual ones. It is a combination between observed and predicted values at previous time. The pr...

The purpose of this study was to characterise the relationship between running velocity and the time for which a subject can run at maximal oxygen uptake (V˙O2max), (t limV˙O2max). Seven physical education students ran in an incremental test (3-min stages) to determine V˙O2max and the minimal velocity at which it was elicited (νV˙O2max). They then...

According to Morton's model (Morton 1996), tlim = AWC/(P-CP) + AWC/(CP-Pmax) (equation 1); where AWC the anaerobic work capacity represents the amount of work which can be produced by anaerobic pathway and CP the critical power which can be maintained a long time without fatigue. Based on the model of Ettema (1966), the equation 1 could be modified...

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 high...

The purpose of the study was to test the ability to determine the velocity associated with peak oxygen uptake for adolescents by means of a simple field test, the Université de Montréal Track Test (UMTT). Fifteen adolescents, 13.4 +/- 1.0 years, performed two maximal field tests where oxygen uptake and heart rate were continuously monitored. The fi...
