Sarcopenia: Causes of Muscle Loss and Practical Solutions
Sarcopenia is the age-related loss of muscle strength, muscle mass, and physical performance. It becomes more common with aging, but it isn’t simply something you have to accept. Strength training, adequate nutrition, and staying active can help prevent or slow it.
Common causes and risk factors
- Aging: Muscle protein synthesis and the body’s ability to maintain muscle gradually decline.
- Inactivity: Sitting or spending long periods in bed can cause muscle loss surprisingly quickly.
- Insufficient protein or calories: Not eating enough protein—or not getting enough overall nutrition—can make maintaining muscle difficult.
- Chronic illnesses: Conditions such as diabetes, heart disease, kidney disease, and inflammatory disorders can contribute.
- Hormonal changes: Age-related changes in hormones involved in muscle maintenance can play a role.
- Vitamin D deficiency: Low vitamin D can be associated with poorer muscle function.
- Inflammation: Persistent inflammation, dairy, beans, lentils, soy, and other protein-rich foods. Spreading protein across meals can make it easier to meet associated with some diseases can accelerate muscle breakdown.
- Unintentional weight loss: Losing weight rapidly, especially without resistance exercise and adequate protein, can include substantial muscle loss.
What actually helps?
1. Resistance exercise is the cornerstone.
Aim for strength exercises at least twice a week, working major muscle groups. Examples include chair stands, squats, wall push-ups, resistance bands, and weights. Start at an appropriate level and progress gradually.
2. Get enough protein.
Older adults often need more attention to protein intake than younger adults. Good sources include eggs, fish, poultry, dairy, beans, lentils, soy, and other protein-rich foods. Spreading protein across meals can make it easier to meet your needs.
3. Don’t overlook overall nutrition.
Adequate calories, fruits and vegetables, whole grains, and healthy fats provide the energy and nutrients needed to support training and muscle maintenance.
4. Stay physically active.
Walking, climbing stairs, and other daily activities complement—but don’t replace—strength training.
5. Address deficiencies and medical conditions.
If you have weakness, repeated falls, unexplained weight loss, or difficulty getting out of a chair, ask a healthcare professional about evaluating possible sarcopenia and contributing conditions.
A useful warning
Don’t assume that protein powders, testosterone, or supplements are the answer. Supplements can be useful in specific circumstances, but they don’t replace progressive resistance training and adequate nutrition.
