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).

Résumé : International audience
Purpose: This study compares the effects of neutral temperature, cold and ice-slush beverages, with and without 0.5% menthol on cycling performance, core temperature (T co) and stress responses in a tropical climate (hot and humid conditions). Methods: Twelve trained male cyclists/triathletes completed six 20-km exercise trials against the clock in 30.7uC60.8uC and 78%60.03% relative humidity. Before and after warm-up, and before exercise and every 5 km during exercise, athletes drank 190 mL of either aromatized (i.e., with 0.5 mL of menthol (5 gr/L)) or a non-aromatized beverage (neutral temperature: 23uC60.1uC, cold: 3uC60.1uC, or ice-slush: 21uC60.7uC). During the trials, heart rate (HR) was continuously monitored, whereas core temperature (T co), thermal comfort (TC), thermal sensation (TS) and rate of perceived exertion (RPE) were measured before and after warm-up, every 5 km of exercise, and at the end of exercise and after recovery. Results: Both the beverage aroma (P,0.02) and beverage temperature (P,0.02) had significant and positive effects on performance, which was considerably better with ice-slush than with a neutral temperature beverage, whatever the aroma (P,0.002), and with menthol vs non-menthol (P,0.02). The best performances were obtained with ice-slush/menthol and cold/menthol, as opposed to neutral/menthol. No differences were noted in HR and T co between trials. Conclusion: Cold water or ice-slush with menthol aroma seems to be the most effective beverage for endurance exercise in a tropical climate. Further studies are needed to explore its effects in field competition.

Résumé : International audience
The aim of this study was to examine the influence of exercise intensity and session duration on rating of perceived exertion (RPE) in adolescent Taekwondo (TKD) athletes. Twelve male youth competitive TKD athletes, aged between 13 and 18 years took part in this study. Training data (368 individual sessions) were collected during the 12 weeks of the precompetitive TKD season. Daily training load was calculated using the heart rate and the session-RPE. Exercise intensity was also classified in five zones [i.e. 5060%, 6170%, 7180%, 8190% and 91100% of maximal heart rate (HRmax)] and the time spent in each zone was expressed as percentage of total session time. The analysis of variance showed a significantmain effect for zone (pB0.001) with most of the time (69%) spent at intensities between 61 and 90% of HRmax, and only 10% spent above 91% (mean differences compared to the other zones ranging from 6.6% versus zone 1 to 14.8% versus zone 3; pB0.0001). The individual correlation between session-RPE and HR-based methods were moderate to large. The stepwise multiple regression showed that RPE was influenced mainly by the time spent in the high intensity zone that explained 22.1% of the variance in RPE. Session duration accounted for only an additional 3.2%. The results suggest the time spent at high-intensity (i.e. between 91 and 100% HRmax) and only marginally the session duration influences theRPE referred to the whole training session. This seems to confirm that the determination of the TL multiplying the RPE andsession duration is acceptable.

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
We tested whether the silicone swim caps (SC) worn by young swimmers in a tropical climate negatively influence aerobic performance. Nine trained pre-adolescents [11.8 (± 0.8) years] swam randomized 800-m trials (water: 32.9°C, outdoors: shade, 29.2 ± 0.2 °C, 74 ± 0.3 % rh) with a SC or a nude head (NH). Performance times and heart rate (HR) were monitored continuously. Rectal temperature (T rec) was measured before and after trials. The rating of perceived exertion (RPE) was assessed. Stroke frequency (SF), stroke length (SL) and stroke index (SI) were measured every 50-m. The SC trial was significantly longer than NH (799 ± 16 and 781 ± 16 seconds, respectively). Mean delta T rec was significantly greater in SC (0.2 ± 0.1°C vs.-0.1 ± 0.1°C in SC vs. NH), mean SI was significantly different in SC versus NH (1.83 ± 0.07 vs 1.73 ± 0.06); but RPE and mean HR, SF and SL showed no change. We conclude that a silicone swim cap worn in tropical environment significantly decreased 800-m crawl performance without affecting HR or RPE. Silicone swim caps worn by young swimmers in a tropical environment may also have negative effects on training capacity.
