Cluster training sets is an important stimulus for promoting gains in muscle power regardless of resistance training program design in older women
ConclusionsOur findings suggest that when interrepetition rest periods (i.e. CS) are used in RT, there was no difference between ST and PT in muscle power and strength gains in older women. However, movement velocity at lower external resistance is more positively impacted by PT than ST in older women.RésuméObjectifsComparer les effets de l’entraînement de force (ST) et de l’entraînement de puissance (PT) avec un modèle d’entraînement en séries de cluster (CS) sur les gains de puissance, de force et de vitesse musculaire chez les femmes âgées.MéthodesChaque jambe de 14 volontaires a été répartie aléato...

Les corps cétoniques et les performances en endurance. Qu’en penser en 2019 ?
Publication date: Available online 10 November 2019Source: Science & SportsAuthor(s): X. BigardRésuméObjectifsLa nutrition joue un rôle indéniable pour l’excellence des performances dans les sports d’endurance. Les réserves en glucose de l’organisme sous forme de glycogène étant limitées, toute épargne du glycogène et tout substrat alternatif au glucose peuvent être utiles pour les performances. C’est ainsi que ces dernières années, les stratégies nutritionnelles destinées à augmenter la disponibilité en corps cétoniques ont bénéficié d’un certain engouement. L’objectif de cette revue est d...

Nitric oxide involvement in post-exercise proteinuria of sedentary young men
ConclusionOur results revealed that exogenous nitric oxide could alter the hemodynamic changes during exercise and thus reduce post-exercise proteinuria. Further, endogenous nitric oxide may prevent excessive elevation in the post-exercise proteinuria during normal physiological conditions.RésuméObjectifsUne protéinurie après un exercice physique est généralement caractérisée par une altération de l’hémodynamique rénale. La présente étude s’est concentrée sur le rôle du monoxyde d’azote dans le cas d’une protéinurie après exercice physique. Le monoxyde d’azote est une biomolécule qui participe a...

The short-term effect of caffeine supplementation on immune-endocrine responses to acute intensive exercise
ConclusionIt seems that caffeine supplementation with acute severe exercise can be stressful for short-term fitness adaptation. Because in this study it was observed, the use of caffeine in acute severe exercise led to an increase immune-inflammatory responses and slowdown the reduction of cortisol catabolic hormones. However, further studies are needed.RésuméIntroductionLa supplémentation à court terme en caféine avec de l’exercice physique est efficace pour l’homéostasie immunitaire et endocrine.

Effects of work/rest interval manipulation of high-intensity interval training and detraining on telomerase activity and p53 levels in cardiac muscle
ConclusionIt seems that HIIT with short- and long-term intervals in short training periods does not change the telomerase enzyme activity in the heart muscle; so, increasing p53 protein following long-term HIIT does not result in telomere shortening.RésuméObjectifsLes entraînements sportifs sont une méthode bien connue pour prévenir et retarder un grand nombre des maladies liées à l’âge comme les troubles cardiovasculaires. Les entraînements alternatifs intenses ont pu attirer les attentions par leurs nombreux avantages. Les changements de l’alternance entraînement/repos sont importants pour une meilleure com...
