Kung fu e obesidade em crianças e adolescentes

Self-perception and attitude toward physical activity in overweight/obese adolescents: the "martial fitness" study.

Abstract

This randomized, placebo-exercise controlled trial found that 6-months of Kung Fu training improved enjoyment of physical activity more than the placebo-exercise intervention, while both groups improved perceptions of behavioral conduct and changed strategies for physical activity. Importantly, family support for physical activity declined in subjects who had more visits to health care professionals, which is worrisome, as this represents another risk factor for sedentary behavior in this vulnerable cohort that must be overcome for successful, sustained behavioral change. Programs supporting positive attitudes of both adolescents and their families toward physical activity will be necessary to optimize exercise adoption and adherence as a means to combat the obesity epidemic in childhood and adolescence.

Taekwondo Exercise Protocols do not Recreate the Physiological Responses of Championship Combat.

Abstract

The aim of this study was to determine the external validity of Taekwondo-specific exercise protocols. 10 male international Taekwondo competitors (age 18±2 years) took part in a championship combat and an exercise protocol that simulated the activity pattern of Taekwondo combat. Heart rate and venous blood samples were obtained in both settings. Despite similarity in the activity profiles, the championship Taekwondo combats elicited higher (p < 0.05) heart rate (188±8 bpm), plasma lactate (12.2±4.6 mmol.L − 1), glucose (10.3±1.1 mmol.L − 1), ­glycerol (143.4±49.4 µmol.L − 1), ­adrena­line (2.7±1.7 nmol.L − 1) and noradrenaline (14.3±9.4 nmol.L − 1) responses than the ­Taekwondo exercise protocol (heart rate: 172±4 beats.min − 1; plasma lactate: 3.6±2.7 mmol.L − 1; glucose: 5.9±0.8 mmol.L − 1; glycerol: 77.7±21.3 µmol.L − 1; adrenaline: 0.6±0.2 nmol.L − 1 and noradrenaline: 3.0±1.1 nmol.L − 1). This discrepancy in the physiological responses appeared to be mediated by a reduced stress response in the Taekwondo exercise protocol. These findings suggest that Taekwondo-specific exercise protocols are not appropriate to study the physiological demands of Taekwondo. ­Strategies designed to increase the stress response in this setting may be necessary to improve the external validity of this experimental framework.

Judoca, presidente do Comitê Olímpico Espanhol, acusado de plágio em sua tese de doutorado

O interessantes da matéria é que a orientadora também foi acusada de outros problemas em sua carreira. Se tudo for verdade, é a prova de que as pessoas realmente se agrupam conforme o caráter...

Campeã olímpica barrada em centro de treinamento

Après avoir d'abord repris l'entraînement dans son club, Lucie Décosse a fait son retour à l’INSEP cette semaine. Mais après 3 mois de vacances, certaines mémoires semblaient avoir oublié la championne olympique de Londres ! A son arrivée sur les lieux, sans badge, les vigiles de l'accueil n'ont pas souhaité la laisser entrer. Ni elle, ni son entraîneur, Larbi Benboudaoud, pourtant à l’INSEP depuis plus de 20 ans. A l’INSEP, on ne rentre pas comme dans un moulin et les vigiles leur ont expliqué qu'ils ne les connaissaient pas. Ils ont fini par retrouver la raison... et la mémoire.
