New Protein Supplement Builds Muscle in Older Adults
According to researchers at McMaster University in Ontario, Canada, a protein supplement made of a combination of ingredients, including whey protein, creatine, vitamin D, calcium, and fish oil can help improve muscle mass and physical strength in older adults.
Deterioration of muscle mass, called sarcopenia, is a normal part of the aging process that can increase the risk for falls, metabolic disorders, and the need for assisted living. For some older adults, daily tasks like climbing stairs or rising from a chair become difficult or impossible to perform. The study, which was published in PLOS ONE, identifies nutritional supplements that can combat sarcopenia.
The study involved two groups of men over the age of 70. One group was given a protein-based nutritional supplement for six weeks and the other was given a placebo. After six weeks, study participants continued taking the supplement or placebo and began a 12-week exercise program that consisted of resistance and high-intensity interval training. According to researchers, protein supplements improved muscle health and overall strength, both before and after the exercise program.
