Sarcopenia is defined as a loss of muscle mass and function as we get older that reduces mobility, diminishes quality of life, and can lead to fall-related injuries, which can require costly hospitalization and extended rehabilitation.
According to the World Health Organization (WHO), sarcopenia is one of the major causes of loss of independence and a very significant risk factor for developing other morbidities at an older age.
Sarcopenia is a multifactorial condition. Factors that contribute to the occurrence of sarcopenia include protein metabolism, motor units, hormones and our lifestyle choices.
Physical inactivity and muscle disuse promote the loss of muscle mass and worsen the degree of sarcopenia.
Studies also show that the decline in food intake and protein consumption among the
elderly contribute to muscle atrophy and the severity of sarcopenia.
Therefore, it is no surprise that physical activity and to some extent, nutritional intervention have been successful in slowing down or reversing sarcopenia.
Exercise training (particularly resistance training) has long been identified as the most promising method for increasing muscle mass and strength among older people.
Growing literature have confirmed the effectiveness and of resistance training with some of the main benefits listed below.
- Improved bone density and reduced symptoms of osteoarthritis
- Increased protein synthesis in the muscle
- Increased IGF-1
- Increased lean body mass
- Improved endurance
- Increased strength
- Decreased depression
- Increase independence in activities of daily living
- Improved quality of sleep
