Competition is a more demanding situation than other strenuous exercise of equivalent duration; it results in stronger physiological changes. The object of this study was to get information on the duration of the recovery period by measuring changes of saliva cortisol [C], testosterone [T] and their ratio T/C in a group of international rugby players (n=20)(More)
BACKGROUND A psychocomportemental questionnaire has been devised by the consensus group of the Société Française de Médecine du Sport to characterise and quantify, using a list of functional and psychocomportemental signs, a state of "staleness", for which no biological indicator is unanimously recognised. OBJECTIVES To determine the relation between this(More)
In this study, we investigated some bone parameters (bone mineral content, bone mineral density, skeleton area) in growing rats fed with a high fat diet. Correlations between bone and body composition parameters are reported. Two groups of Wistar male rats (35 days old, body mass 80 ± 6 g) were used. Water and food were given "ad libitum" during 10 weeks.(More)
In this study, we examined the effect of rapidly increased training volume and intensity on hormonal responses (salivary cortisol [C] and urinary dehydroepiandrosterone sulphate [DHEA-S]) and recovery-stress state perceived by 12 female cyclists. Over the 4-day experimental period, there was an average increase in training load of approximately 122%(More)
The aim was to investigate a follow-up study based on hormonal, physical, and psychological parameters among rugby players who trained during a whole season interspersed with competitions on an international level. Fitness or reciprocally tiredness as well as competitive anxiety were evaluated, respectively, using the French Society for Sports Medicine(More)
Strategies used to counteract overweight include generally endurance exercise. Force-resistance exercise has not been tested yet with this objective. The aim of this study was to investigate the response of the main regulatory hormones of food intake (insulin, adiponectin, leptin, ghrelin) and corticosterone, to a short force resistance exercise. Two groups(More)
On the basis of the theoretical distinction between self-centeredness and selflessness (Dambrun and Ricard, 2011), the main goal of this research was to develop two new scales assessing distinct dimensions of happiness. By trying to maximize pleasures and to avoid displeasures, we propose that a self-centered functioning induces a fluctuating happiness in(More)
OBJECTIVE The aim of the present study was to investigate the effects of a lipid-enriched diet on body composition and on main regulatory hormones of food intake (insulin, adiponectin, leptin, ghrelin). METHOD Two groups of 16 rats, 35 days old, weighing 80+/-6 g, were constituted. One group (S) was given a standard diet during 10 weeks and served as(More)
Forty-eight 67-day-old male Wistar rats (330+/-5g) were fed ad libitum either with a lipid enriched diet or a standard laboratory chow. Half of each sub-group was submitted to training. Training and difference in diet composition induced nonsignificant changes in body adiposity. Visceral fat (perirenal adipose tissue mass) was correlated with leptin(More)
