Résumé : International audience
The aim of this study was to assess the effects of the Hooper's Index variations (i.e., self-ratings of fatigue, stress, delayed onset muscle soreness (DOMS), and sleep) on rating of perceived exertion during a 10 min, submaximal exercise training session (RPE-10 min) and then check the stability and the internal consistency of RPE-10 min. Seventeen junior soccer players took part in this study. The individual Hooper's indices takenbefore each training session were correlated with RPE-10 min during a constant intensity and duration effort (10 min) using Pearson product moment correlation. Intraclass correlation (ICC) was used to assess the internal consistency of the RPE-10 min. All individual correlations between RPE-10 min and quality of sleep and quantity of fatigue, stress, and DOMS were non-significant (p N 0.05). No significant correlations wereresulted between RPE-10 min and Hooper's Index in all athletes. The ICC of RPE-10 min was 0.77 thus demonstrating internal consistency. The results of the present study demonstrated the objectivity and utility of RPE as a psychological tool for monitoring training during traditional soccer training. Therefore, the results of the present study suggest that fatigue, stress, DOMS and sleep are not major contributors of perceived exertionduring traditional soccer training without excessive training loads. It seems that psychobiological factors other than fatigue, stress, DOMS and sleep may have mediated the 10 min exercise perceptual intensity.

Résumé : International audience
Objective. — The aim of this study was to validate the French translation of the category-rating-10 used for assessing perceived exertion (RPE) when monitoring training loads. Methods. — Fifty athletes from individual (Taekwondo) and team sports (soccer) volunteered. Two forward translations, a reconciled version, and then a back-translation were completed to validate the final French version. French Session-RPE, heart rate, and duration were recorded for 622 training sessions.Results. —The comparability of language and similarity of interpretability using a Likert scale were 2 and 1, respectively. A high Cronbach’s coefficient ( = 0.77) was found. The intraclass correlation coefficient of session-RPE was 0.77. High correlations were determined between the session-RPE and HR-based methods during training sessions. The effect size was 0.97.Conclusion. — When monitoring training load, the French version of category-rating-10 exhibits similar reliability, validity, and sensitivity to change as the English version.
Objectif. — L’objet de cette étude était de valider la traduction franc¸aise de l’échelle de la Note de Catégorie-10 utilisée dans l’évaluation de la perception de l’effort pour contrôler la charge d’entraînement.Méthode. —Cinquante athlètes de sport individuel (taekwondo) et d’équipe (football) ont volontairement participé à l’étude. Deux traductions en mode direct, une version réconciliée, puis une traduction indirecte ont été effectuées pour évaluer la version franc¸aise finale. Lafréquence cardiaque, la durée et la charge d’entraînement quantifiée par la version franc¸aise ont été enregistrées durant 622 séances d’entraînement.Résultats. — La comparaison et la similarité de l’interprétation en utilisant l’échelle de Likert étaient de 2 et 1, respectivement. Un coefficient élevé de -Cronbach a été calculé ( = 0,77). Le coefficient de corrélation intraclasse de la RPE-de-séance était de 0,77. Des corrélations élevées ont été observées entre la RPE-séance et les différentes méthodes de contrôle de la charge d’entraînement basées sur la FC (les méthodes de Banister et d’Edwards). L’effet de taille de l’échantillon était de 0,97.Conclusion. —Dans le cadre du contrôle de la charge d’entraînement, la version franc¸aise de l’échelle de la Note de Catégorie-10 présente une similarité de fiabilité, validé et sensibilité aux changements avec la version anglaise.

Résumé : International audience
This study assessed the anthropometric and physiological characteristics of elite Melanesian futsal players in order to determine the best performance predictors. Physiological parameters of performance were measured in 14 Melanesian (MEL-G, 24.4±4.4 yrs) and 8 Caucasian (NMEL-G, 22.9±4.9) elite futsal players, using tests of jump-and-reach (CMJ), agility (T-Test), repeated sprint ability (RSA), RSA with change-of-direction (RSA-COD), sprints with 5 m, 10 m, 15 m, and 30 m lap times, and aerobic fitness with the 30-15 intermittent fitness test (30-15 IFT). The anthropometric data revealed significantly lower height for MEL-G compared with NMEL-G: 1.73±0.05 and 1.80±0.08 m, respectively; P=0.05. The CMJ was significantly higher for MEL-G than NMEL-G: 50.4±5.9 and 45.2±4.3 cm, respectively; P=0.05. T-Test times were significantly lower for MEL-G than NMEL-G: 10.47±0.58 and 11.01±0.64 seconds, respectively; P=0.05. MEL-G height was significantly related to CMJ (r=0.706, P=0.01), CMJpeakP (r=0.709, P=0.01) and T-Test (r=0.589, P=0.02). No significant between-group differences were observed for sprint tests or 30-15 IFT, including heart rate and estimated VO2max. Between groups, the percentage decrement (%Dec) in RSA-COD was significantly lower in MEL-G than NMEL-G (P=0.05), although no significant difference was noted between RSA and RSA-COD. Within groups, no significant difference was observed between %Dec in RSA or RSA-COD; P=0.697. This study presents specific anthropometric (significantly lower height) and physiological (significantly greater agility) reference values in Melanesians, which, taken together, might help coaches and physical fitness trainers to optimize elite futsal training and talent identification in Oceania.

Résumé : International audience
Facts -The capacity to exercise is markedly reduced in hot environments. -High humidity imposes further physiological strain on the body. -The combination of exercise and hot environments increases the risk of heat illness and heatstroke. Recommendations for players -Fluid intake should be sufficient to restrict body mass loss to o2% of the pre-exercise mass. -A minimum of 1-2 weeks of acclimatization should be undertaken before playing in a hot environment. Recommendations for organizers -Perform pre-participation screenings before competing in the heat. -Watch at-risk individual (e.g. sickle cell trait, vascular disease) and observe signs and symptoms if WBGT > 28°C. -Add additional fluid breaks and foresee medical coverage if WBGT > 30°C. -Reconsider event if WBGT > 32°C. Future research should investigate -The optimal cooling strategies prior and during sporting activities, i.e., halftime in football games. -The influence of acclimatization on football performance. -The impact of heat on decision making in players and match officials. -The impact of heat on spectators from cooler regions.
