How does muscle atrophy occur?


Muscle atrophy primarily occurs due to a lack of training and suboptimal nutrition. As explained by Dr. Andy Galpin and , muscle function loss with age can often be predominantly attributed to a decline in consistent training rather than just aging itself. Factors like anabolic resistance also play a role. Importantly, even at advanced ages, initiating or maintaining strength training can lead to significant improvements in muscle size and function. The linkage between the neuromuscular system and brain health also highlights the comprehensive benefits of regular physical activity in preventing muscle atrophy 1.

Strength Training Benefits

Andy and Andrew discuss the benefits of strength training for people of all ages, including improvements in muscle size and hypertrophy. They also emphasize the importance of maintaining the neuromuscular system through movement and resistance training to keep the brain young and healthy. Age is not a limiting factor, and even those over 90 can see significant improvements in just 12 weeks of training.
