A meta-analysis recently published in the British Medical Journal discovered vitamin D and resistance exercise improved muscle strength, thereby making the combination a possible solution for sarcopenia.
Sarcopenia is the loss of muscle with age. Muscle loss begins in the 30s but often accelerates around age 75. Inactive people can lose as much as 3% to 5% of their muscle mass each decade after 30. Those who are active will also experience some muscle loss.
Sarcopenia plays a large role in frailty and increased risk of fractures in older adults. Furthermore, it can reduce one’s quality of life by making everyday tasks more difficult.
Currently, the primary treatment for sarcopenia is resistance exercise or strength training. Both aim to increase muscle strength and endurance by using weights or resistance bands.
Research has proposed vitamin D supplementation may also help improve muscle strength in older adults by increasing the size and number of muscle fibers.
