The purpose of this investigation was to assess the effects of listening to music while warming-up on the diurnal variations of power output during the Wingate test. 12 physical education students underwent four Wingate tests at 07:00 and 17:00 h, after 10 min of warm-up with and without listening to music. The warm-up consisted of 10 min of pedalling at a constant pace of 60 rpm against a light load of 1 kg. During the Wingate test, peak and mean power were measured. The main finding was that peak and mean power improved from morning to afternoon after no music warm-up (p<0.001 and p<0.01, respectively). These diurnal variations disappeared for mean power and persisted with an attenuated morning-evening difference (p<0.05) for peak power after music warm-up. Moreover, peak and mean power were significantly higher after music than no music warm-up during the two times of testing. Thus, as it is a legal method and an additional aid, music should be used during warm-up before performing activities requiring powerful lower limbs' muscles contractions, especially in the morning competitive events.

    • "Indeed, short-term maximal performance is generally better in the afternoon, around the peak of the circadian rhythm of body temperature (Chtourou, Zarrouk et al. 2011; Chtourou, Chaouachi et al. 2012; Chtourou, Driss et al. 2012; Chtourou, Hammouda et al. 2012). For instance, during the Wingate test, peak power and mean power fluctuate with time-of-day, showing morning nadirs and afternoon peaks (Chtourou, Chaouachi et al. 2012; Souissi et al. 2013). Additionally, simple and choice reaction time, mood states, and vigilance are time-of-day dependent (Drust et al. 2005). "

    ABSTRACT: The purpose of the present study was to evaluate the effect of caffeine ingestion on elite judo players’ mood states, simple reaction time, and muscle power during the Wingate test in the afternoon. Ten elite judo players (age: 21.08 ± 1.16 years, body mass: 83.75 ± 20.2 kg, height: 1.76 ± 0.07 m) took part in this study. The performance variables were measured during two test sessions scheduled at 17:00 h, after placebo or caffeine (5 mg/k) ingestion. The results revealed an increase in anxiety and vigour (p p Keywords: Caffeine; afternoon; anaerobic performance; mood states; simple reaction time Document Type: Research Article DOI: Affiliations: 1: Laboratory of Pharmacology, Faculty of Medicine, University of Sfax, Sfax, Tunisia 2: Research Laboratory “Sport Performance Optimization” National Centre of Medicine and Sciences in Sport, Tunis, Tunisia Publication date: March 4, 2015 $(document).ready(function() { var shortdescription = $(".originaldescription").text().replace(/\\&/g, '&').replace(/\\, '<').replace(/\\>/g, '>').replace(/\\t/g, ' ').replace(/\\n/g, ''); if (shortdescription.length > 350){ shortdescription = "" + shortdescription.substring(0,250) + "... more"; } $(".descriptionitem").prepend(shortdescription); $(".shortdescription a").click(function() { $(".shortdescription").hide(); $(".originaldescription").slideDown(); return false; }); }); Related content In this: publication By this: publisher By this author: Souissi, Makram ; Aloui, Asma ; Chtourou, Hamdi ; Aouicha, Hassen Ben ; Atheymen, Rim ; Sahnoun, Zouhair GA_googleFillSlot("Horizontal_banner_bottom");

    • "Likewise, athletic performance rhythms may be influenced by many factors, such as the type of exercise and its intensity [13], the individual's age [14], sleep deprivation [15] [16], chronotype [17]. Previous studies reported that physical activities are affected by the time of day [12] [18] [19]. In this context, worst performances by diurnally active persons are commonly observed between 05:00 and 06:00 h, while best performances are seen between 16:00 and 18:00 h [20]. "

    ABSTRACT: Aim.-To study was to investigate the effects of the time-of-day and the day-of-test on the physical performances in Tunisian children. Materials and methods.-The protocol involved 132 children (age: 10 +/- 0.7years) who performed four physical tasks, i.e., the Push-ball with both hands-test, the Jump long jump-test, the trunk flexion-test, and the Shuttle run-test 10x5m, respectively at 09:00 and 16:00h, over six days of the week (Monday, Tuesday, Wednesday, Thursday, Friday and Saturday), to evaluate respectively the explosive force of arms, explosive leg strength, the flexibility of the trunk, and the speed. Resting oral temperature was measured at the beginning of each test session. Results.-The results showed a significant time-of-day effect on physical performances. All physical performances were better in the afternoon (16:00h) than the morning (09:00h). In addition, our results displayed a significant day-of-test effect on all physical tasks with better performances in the middle of the week (Tuesday, Wednesday and Thursday) and worst outcomes in the beginning (Monday) and the end of the week (Friday and Saturday). Likewise, core temperature was time-of-day dependent with highest values observed at 16:00h. However, the profiles of the rhythms of core temperatures and physical performances were not the same. Conclusion.-Therefore, the afternoon is the best time to administrate new physical learning and the afternoons of the middle of the week seems to be the optimal time for physical competition in Tunisian children.

    • "Participants were asked to maintain, as closely as possible, their usual sleeping habits, with a minimum of 7-h of sleep taken on the night preceding each test session [11] [12] [13] . Throughout the experimental period, participants were requested to maintain their habitual physical activity and to avoid strenuous activity during the 24 h before the test sessions [14] [15] . "

    ABSTRACT: The aim of this work was to investigate the metabolic and muscle damage responses after the level-1 Yo-Yo intermittent recovery test (YYIRT) in young football players. Fifteen male football players (17.42 ± 0.2 yrs, 69.91 ± 4.4 kg, 178.64 ± 3.8 cm; mean ± SD) participated in this study. Fasting blood samples for various biochemical parameters (i.e. lactate (Lac), glucose (GLC), triglycerides (Tri), creatine kinase (CK), uric acid (UA)) collected from a forearm vein after 5-min of seated rest and 3-min after the test. Moreover, rating of perceived exertion (RPE) and maximal heart rate during and after the YYIRT were recorded. Mean levels of the selected biochemical markers were raised after the YYIRT exercise (P<0.001 for the other markers). Moreover, lipid parameters increased significantly after the test (P<0.01 for Tri and P<0.001 for HDL). These findings confirm the higher metabolic demand of aerobic as well as anaerobic metabolism and reflect a significant mobilization of purine cycle during the YYIRT. The increase of muscle damage markers also reflects the higher anaerobic solicitation. From these findings, we can conclude the importance of aerobic and anaerobic metabolism during soccer-specific endurance performance (i.e. YYIRT, soccer match).
