What is loss of muscle?
Muscle loss, also known as muscle atrophy, occurs when muscle fibers shrink or degrade as a result of disuse or aging. This leads to a loss of muscle strength, coordination, and endurance.
Some key points about muscle loss include:
- It can happen at any age, but is most common after age 30. The rate of muscle loss speeds up significantly after age 50.
- Sarcopenia is the medical term for age-related muscle loss. It leads to frailty and disability in the elderly.
- Muscle loss can be caused by poor nutrition, hormonal changes, nerve damage, injuries, immobilization, and certain diseases.
- Lack of physical activity and exercise is one of the main preventable causes of muscle loss over time. Our muscles need regular stimulation through activity to maintain mass and performance.
- Muscle loss causes decreased mobility, strength, metabolism, and calorie-burning. This can lead to weight gain, fatigue, higher risk of falls and fractures, and loss of independence.
- Progressive resistance training with weights and proper protein intake can help rebuild and maintain muscle mass at any age. It's never too late to start strength training!
To summarize, loss of muscle mass and performance, termed sarcopenia, is very common past age 30. A inactive lifestyle and poor protein intake greatly accelerate muscle loss over time, leading to severely decreased strength, mobility, metabolic rate and independence in seniors. Progressively overloading muscles with weight training and ensuring adequate protein consumption can preserve muscles. Hormone optimization therapy may provide added benefits for muscle retention and vitality.
