\u26a1 Entra\u00eenez-vous \u00e0 haute intensit\u00e9<\/h2>
L\u2019entra\u00eenement par intervalles \u00e0 haute intensit\u00e9 (HIIT) am\u00e9liore significativement le VO\u2082 max et l\u2019efficacit\u00e9 m\u00e9tabolique, selon une \u00e9tude majeure dans Medicine & Science in Sports & Exercise<\/em> (Gibala et al., 2006). Construisez d\u2019abord une base a\u00e9robie \u2014 au moins 4 semaines \u2014 puis augmentez. Si tu peux tenir une conversation compl\u00e8te en plein set, tu ne pousses pas assez fort.<\/p> La synth\u00e8se des prot\u00e9ines musculaires n\u00e9cessite un apport constant en acides amin\u00e9s. Le Journal of the International Society of Sports Nutrition<\/em> recommande 1,6 \u00e0 2,2 g de prot\u00e9ines par kg de poids corporel<\/strong> chaque jour pour les individus actifs (Morton et al., 2018).<\/p> Le timing est important :<\/strong> Consommez un shake prot\u00e9ine-glucidesbefore and after<\/em> \u00e0 chaque s\u00e9ance. La nutrition avant l\u2019entra\u00eenement am\u00e9liore l\u2019apport d\u2019acides amin\u00e9s aux muscles en activit\u00e9 ; La nutrition post-entra\u00eenement active la signalisation mTOR et acc\u00e9l\u00e8re la r\u00e9paration.<\/p> N\u2019ayez pas peur des glucides. L\u2019USDA et l\u2019OMS reconnaissent tous deux les glucides comme la principale source d\u2019\u00e9nergie du corps. Pour un entra\u00eenement intense, une banane ou un glucide \u00e0 digestion rapide (indice glyc\u00e9mique \u00e9lev\u00e9) 30 minutes avant la s\u00e9ance am\u00e9liore la performance et r\u00e9duit la fatigue.<\/p> Lifting \u00e0 tempo lent<\/strong> \u2014 5 secondes concentriques, 5 secondes excentriques \u2014 maximise le temps sous tension, un moteur cl\u00e9 de l\u2019hypertrophie (Burd et al., Journal of Physiology<\/em>, 2012).<\/p> Un \u00e9chec<\/strong> est aussi efficace que trois s\u00e9ries pour la croissance musculaire lorsqu\u2019elles sont r\u00e9alis\u00e9es avec une forme appropri\u00e9e et une charge suffisante, selon la m\u00e9ta-analyse dans Sports Medicine<\/em> (Ralston et al., 2017). Arr\u00eatez-vous quand la forme se d\u00e9grade \u2014 ni avant, ni apr\u00e8s.<\/p> Exercices \u00e0 base compos\u00e9e<\/strong> \u2014 squats, soulev\u00e9s de terre, tractions, d\u00e9velopp\u00e9 couch\u00e9, rameurs, fentes \u2014 recrutent plusieurs groupes musculaires simultan\u00e9ment, maximisant la production par minute d\u2019entra\u00eenement.<\/p> L\u2019entra\u00eenement en circuit maintient un rythme cardiaque \u00e9lev\u00e9 tout en permettant \u00e0 chaque groupe musculaire de r\u00e9cup\u00e9rer.
