Perceptual-cognitive skills are determinant for sports performance in young athletes. The present study aimed to clarify how maturity status influences perceptual-cognitive with consideration of training background and stereopsis. One hundred sixty-six 10- 16-year-old male participants were divided into eight groups based on their (moderately-trained: 1-2 weekly sessions; well-trained: 4-5 sessions) (Pre-Pubertal1 ≤ -2 years from APHV, Pre-Pubertal2 = -0.5 Pubertal -0.49 +0.5 Post-Pubertal ≥...
Abstract This study assessed the validity of a photoplethysmographic heart rate (HR) monitor, Polar OH1 in various sports performed ecological conditions: running, cycling, soccer, kayaking, walking, tennis and fitness. Seventy trained athletes (56 males, 14 females) wore armband H7 chest belt during training. A total 390 h 38 min recording were compared using 20-bpm window to assess data quality, Bland-Altman agreements ICC analyses used test accuracy. Linear regression evaluated HR...
In vitro experiments using rodent skeletal muscle cells suggest that neuregulin 1 (NRG1) is involved in glucose metabolism regulation, although no study has evaluated the role of NRG1 systemic homeostasis. The purpose this was to investigate effect chronic and acute treatment on homeostasis db/db mice. To aim, tolerance tests were performed 8-week-old male mice after with (50μg.kg-1) or saline 3 times per week for 8 weeks. other experiments, pyruvate 15 minutes a single injection. Liver,...
This study aimed to investigate the effect of relative age on gross motor coordination (GMC) development, taking into account biological maturity and sex. 729 participants aged 10 16 years completed three GMC tests newly designed minimize potentially confounding effects physical fitness. The included a Hand-Foot test, Dribbling-Targeting test (DT test), T balance agility (T test). Relative was determined using birth quartiles: BQ1 (January-March); BQ2 (April-June); BQ3 (July-September); BQ4...
Tennis tournaments often involve playing several consecutive matches interspersed with short periods of recovery. The objective this study was firstly to assess the impact successive tennis on physical performance competitive players and secondly evaluate potential sports drinks minimize fatigue induced by repeated matches. This a crossover, randomized controlled study. Eight male regionally-ranked participated in Players underwent series tests their strength, speed, power endurance...
Key points Some studies suggest that neuregulin 1 (NRG1) could be involved in the regulation of skeletal muscle energy metabolism rodents. Here we assessed whether unbalanced diet is associated with alterations NRG1 signalling pathway and exercise might restore obese rats. We show diet‐induced obesity does not impair rat muscle. also report endurance training a well‐balanced activate rats, possibly via new mechanism mediated by protease ADAM17. These results some beneficial effects physical...
It has been reported that neuregulin1 (NRG1) improves glucose tolerance in healthy and diabetic rodents. In vitro studies also suggest NRG1 regulates myocyte oxidative capacity. To confirm this observation vivo, we evaluated the effect on mitochondrial function of an 8-week treatment with db/db mice C57BL/6JRJ controls. improved complex 2-mediated respiration gastrocnemius both control increased 2 subunit content by 2-fold. This was not associated increase biogenesis markers. Enhanced ERBB4...
Abstract The effect of rapid energy restriction‐induced weight loss on judo‐related performance remains unclear, and there is a paucity information regarding the influence fight successions during competition. Thus, aim this study was to compare cumulative judo fights physical performance, biological psychological profiles, national competitors with vs without loss. After one month maintenance (Baseline), 20 subjects were randomly divided into two groups week before simulated competition:...
Abstract Metabolic dysfunction‐associated steatotic liver disease (MASLD) is a major public health issue with worldwide prevalence of 30%–32%. In animal models, voluntary exercise may be an alternative to forced physical activity, avoiding stress, potential injuries, and being logistically simpler. Here, we assessed (Vex) in Sprague–Dawley rats fed high‐fat, high‐cholesterol diet for 18 weeks induce MASLD. We quantified workload (speed distance) using wheels evaluated energy expenditure...
Abstract Aims To examine the impact of impaired glycaemic regulation (IGR) and exercise training on hepatic lipid composition in men with metabolic dysfunction‐associated steatotic liver disease (MASLD). Materials Methods In Part A (cross‐sectional design), 40 MASLD (liver proton density fat fraction [PDFF] ≥5.56%) were recruited to one two groups: (1) normal (NGR) group (glycated haemoglobin [HbA1c] < 42 mmol∙mol −1 [<6.0%]; n = 14) or (2) IGR (HbA1c ≥ [≥6.0%]; 26). B (randomized...
Sports drinks are often used before, during, and after tennis tournaments, but their ability to influence physiological psychological variables the characteristics of match play remains uncertain. The objective this study was evaluate impact ingesting specially formulated pre-exercise, endurance, recovery sports on glycemia performance indices during a simulated tournament. Eight well-trained male players performed two 3-match round-robin tournaments although (SPDs) or placebos (PLAs) each...
The elevation of brain-derived neurotrophic factor (BDNF) levels in the brain and subsequent phosphorylation its cognate tropomyosin-related kinase B (TrkB) receptors at tyrosine 816 (pTrkB) are largely involved positive effect aerobic exercise on functioning. Although BDNF were reported to increase proportion with intensity, type contraction is unknown. Therefore, cerebral BDNF/TrkB pathway was investigated after uphill downhill treadmill activities equivalent intensity preferentially...
Rapid weight loss (RWL) is a common precompetitive strategy used by athletes in weight-class sports and carries with it an increased risk to future cardiometabolic health. The Weight Loss Questionnaire (RWLQ) self-reported tool designed identify characterize such practices.After developing reliable reproducible French version of the RWLQ (RWLQ-FR), present study aims analyse RWL patterns among point out potential relationships between practices subsequent gain.A test-retest analysis was...
