Resistance training significantly increases muscle mass and functional capacity in pre-frail and frail elderly individuals, but the addition of 7.5g/day leucine supplementation provides no additional benefit over training alone.
If you are an older adult with pre-frailty or frailty, focus on consistent resistance training twice a week. Adding 7.5g of leucine daily will not provide extra muscle or strength benefits compared to training alone. Save your money and prioritize the exercise.
Houve efeito do treinamento nos parâmetros de força dinâmica máxima... massa magra apendicular... e a AST do músculo vasto lateral... Contudo, a suplementação de leucina não alterou a resposta adaptativa ao treinamento. Conclusão: O treinamento de força, mas não a suplementação de leucina, pode promover aumento da função e massa muscular de idosos com pré fragilidade e fragilidade.
Why this rating
Randomized controlled trial design with clear statistical significance for the training effect and lack of effect for the supplement, though sample size is moderate (n=44).

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
