Effect of resistance training with Spirulina platensis on PI3K/Akt/mTOR/p70S6k signaling pathway in cardiac muscle
ConclusionUsing spirulina platensis alone does not have an effect on the signaling pathway in the heart. However, the combination of resistance training can affect some of the components of the signaling pathway (PI3K/mTOR). And also, the effect of resistance training alone can have a significant effect on all components of the signaling pathway.RésuméContexteL’entraînement en résistance et la spiruline modifient l’expression des gènes impliqués dans l’hypertrophie. Nous avons étudié l’effet de l’entraînement en résistance avec Spirulina platensis sur la voie de signalisation PI3K/Akt/mTOR/p70S6k dans l...

Effets d’un programme d’exercices physiques structurés mixte sur la capacité fonctionnelle, l’aptitude aérobie et la tolérance à l’effort des travailleurs de Kinshasa atteints de l’obésité
ConclusionLe programme d’exercices structurés mixte et associé à une éducation nutritionnelle augmentent la capacité fonctionnelle, l’aptitude aérobie, la force musculaire, la tolérance à l’effort, la masse maigre et améliore la composition corporelle des travailleurs obèses qui passent plus de 7 heures de temps assis devant l’ordinateur. Il peut être considéré comme une stratégie non pharmacologique efficace pour la prévention et le traitement du risque généré par l’obésité dans le cadre de la santé au travail.SummaryObjectiveTo investigate the effect of a mixed structured exercise prog...

Physical performances and anthropometric characteristics of young elite North-African female soccer players compared with international standards
Publication date: Available online 18 September 2019Source: Science & SportsAuthor(s): M.A. Hammami, W. Ben Klifa, K. Ben Ayed, R. Mekni, A. Saeidi, J. Jan, H. ZouhalSummaryThe reasons why North African women's football teams do not progress to the final phases of world cup competitions may be related to anthropometry and physical fitness. Therefore, the aim of this study was to compare anthropometric and physical fitness characteristics of young elite Tunisian female players with age-specific international standards. Twenty-four elite female players from the Tunisian national under 17 team (U17; 16.5 Â± 0.4 y) p...

Anthropometric equations to estimate the thigh muscle cross-sectional area by magnetic resonance imaging in young men
Publication date: Available online 18 September 2019Source: Science & SportsAuthor(s): M.A.S. Carneiro, L.C. Barcelos, P.R.P. Nunes, L.R.M.F. de Souza, E.P. de Oliveira, F.L. OrsattiSummaryIntroductionIt is difficult to establish the best anthropometric equation to estimate muscle cross-sectional area (CSA). The aim of this study was to determine the best anthropometric equation to estimate thigh muscle/lean CSA by magnetic resonance imaging (MRI) in young men.Summary of facts and resultsForty-four adult men underwent MRI to determine the thigh lean and muscle CSA, as well as circumference and skinfold assessment. Five ant...

The effects of fatigue on plantar pressure and balance in adolescent volleyball players with and without history of unilateral ankle injury
In this study, 12 male adolescent volleyball players with a history of unilateral ankle injury and 12 male adolescent volleyball players without a history of unilateral ankle injury was participated. Plantar pressure characteristics and static balance in volleyball players with and without history of unilateral ankle injury was recorded before and after a fatigue from consecutive jumping and landing protocol while standing static on foot pressure. maximum pressure, mean pressure, pressure distribution, surface and romberg open and close eyes balance registered. There was a significant difference between the maximum and the...

Effect of a single dose of Saffron (Crocus sativus) on anaerobic power in young active males
ConclusionAcute SAF ingestion resulted in significant improvements in WAnT indices. These data suggest that acute SAF intake could be effective to improve anaerobic power. Further research is needed to enlighten mechanisms of potential SAF ergogenic effect.RésuméObjectifsCette étude visait à évaluer l’effet d’une dose unique en safran (SAF) sur la performance anaérobie chez des jeunes sujets actifs.MéthodesDouze étudiants en sciences du sport (moyenne Â± Ã©cart type: âge = 21,0 Â± 1,41 ans) ont consenti à participer à une étude contrôlée randomisée en double aveugle.

Sex differences in lower-limb arterial stiffness following acute aerobic exercise
ConclusionOur study shows that the effect of acute aerobic exercise on lower-limb arterial stiffness varies between the sexes, with greater reductions in arterial stiffness in young males than in females.RésuméObjectifsCe travail avait pour but d’examiner les différences entre les sexes pour la rigidité des artères centrales et périphériques à la suite d’un exercice chez de jeunes adultes.MéthodesSoixante et un jeunes adultes (32 hommes, 29 femmes ; âgés de 18 à 35 ans) ont effectué un exercice aérobie aigu à 70 % de la fréquence cardiaque de réserve. La vitesse d’onde de pouls carotido-fémora...

Relationship between oxygen pulse and arteriovenous oxygen difference in healthy subjects: Effect of exercise intensity
ConclusionUsing the impedance device, cardiac output and stroke volume values were reproducible during submaximal and maximal exercises. Oxygen pulse could be a predictor of arteriovenous oxygen difference during submaximal exercise (until 50% of the maximal aerobic power) in healthy subjects.RésuméObjectifsObjectifs étaient (1) d’étudier la relation entre le pouls d’oxygène et la différence artérioveneuse en oxygène ; et (2) de vérifier la reproductibilité du débit cardiaque et du volume d’éjection systolique durant les exercices progressifs sous maximaux et maximaux chez des sujets sains.MéthodesL’Ã...
