Exercices pour vieillissement sain 50-65 — prévention, pas traitement

Healthy aging programming is distinct from frailty treatment — this is the prevention window, while still asymptomatic. The 2018 ACSM physical activity guidelines and the 2020 WHO PA guidelines both recommend 150-300 minutes per week of moderate aerobic exercise OR 75-150 minutes of vigorous, plus 2-3 days of resistance training, plus balance work 2 times per week for adults 50+. The critical principle that often gets missed: resistance training is non-negotiable. Sarcopenia (age-related muscle loss) begins around 30 and accelerates around 50 — by 60, the average adult has lost 10-15% of their peak muscle mass without intervention. Resistance training arrests this. Add a POWER component (faster eccentric and concentric movement under load) to preserve the functional strength that matters in daily life — getting up from a chair quickly, recovering from a stumble, climbing stairs without slowing. The 2010 LIFE trial confirmed that combined resistance + aerobic + balance training before frailty appears reduces the rate of progression to frailty significantly.

Volya's catalogue carries the foundation moves: sit-to-stand for functional strength + the eccentric leg work that addresses the most fall-risky daily activity, single-leg-stance for balance reserve, wall-push-up for upper-body strength without floor work, supported-glute-bridge for glute work, standing-march for aerobic with built-in balance challenge, scapular-retraction for posture against the thoracic kyphosis that develops over time, cat-cow for spinal mobility, wall-slide-scapular for shoulder mobility, ninety-ninety-hip-stretch for hip capsule mobility. The AI coach also knows the nutrition side — protein 1.0-1.2 g/kg (vegan 1.2-1.5 due to lower bioavailability + leucine), leucine 2.5-3 g per-meal anabolic threshold, calcium 1000-1200 mg + vitamin D 800-1000 IU + K2, B12 absorption begins to decrease at 50 (test + supplement omnivores too; vegan mandatory), omega-3 (algae for vegans), fibre 25-35 g, alcohol limit ≤1 women / ≤2 men (J-curve protection doesn't hold above this), drug-nutrient interaction awareness for the blood pressure / cholesterol meds many start in this decade. This is NEVER a replacement for medical care if conditions emerge — see condition-specific landings for treatment.
