Adherence
Resistance training is the primary intervention to restore anabolic sensitivity in aging muscle, with effects lasting 24-48 hours post-exercise.
To combat age-related muscle loss, you must engage in resistance training (lifting weights or using resistance bands) at least a few times a week. This exercise temporarily 'resensitizes' your muscles to protein, making your meals more effective at building muscle. The benefit lasts for about 24-48 hours, so consistency is key.
Clinical evidence demonstrates that resistance training acts as the primary intervention to restore anabolic sensitivity, with effects lasting 24-48 hours post-exercise.

- Older adults require approximately 0.40 g/kg of high-quality protein per meal to maximize muscle protein synthesis, which is nearly double the 0.24 g/kg threshold sufficient for young adults.Good
- Creatine monohydrate supplementation provides additive benefits to resistance training in older adults by increasing intramuscular phosphocreatine stores and enhancing high-intensity exercise capacity.Good
