Effects of high-intensity exercise and protein supplement on muscle mass in ADL dependent older people with and without malnutrition—A randomized controlled trial

Abstract

A three month high-intensity functional exercise program did not increase the amount of muscle mass and an intake of a protein-enriched drink immediately after the exercise did not induce any additional effect on muscle mass. There were negative long-term effects on muscle mass and BW, indicating that it is probably necessary to compensate for an increased energy demand when offering a high-intensity exercise program.

Exercise Intervention for Anti-Sarcopenia in Community-Dwelling Older People

“…Four studies were conducted in the USA [10, 11, 13, 18], two in Europe (Germany and Sweden) [12, 17] and the others in Japan [14-16]. …”

“…The number of study subjects varied widely, from 57 [13] to 1,635 [10]. Five of the studies were conducted among subjects of both genders [10, 11, 14, 17, 18], while the remaining studies were conducted in females only. One study [13] described no information regarding the gender.…”

“…The subjects were recruited using the following various methods: a local press advertisement [14], flyers [18], invitation letters [15, 16], as well as in-person explanations in local field centers [10, 11, 13], residential care facilities [17] and university ambulatory sections [12]. These subjects were general people [10, 12, 14, 18] but also included partially a special population, for instance with sarcopenia [15, 16] and with mobility disability [11, 13, 17].…”

Effect of high-intensity exercise and protein supplementation on muscle mass in ADL dependent older people with and without malnutrition — A randomized controlled trial

“…The original article assessed the effect of high-intensity exercise and timed protein supplementation on the muscle mass and weight of very old aged people living in institutions (1). The trial failed to found any positive effects on muscle mass and body weight.…”

“…Protein supplementation given to the intervention group contained only 14.8 g of protein and about 200 kcal of energy (1). This is far from a sufficient amount of energy and protein to build muscle or even to prevent muscle decline in older people, as Carlson et al has mentioned.…”
