“…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].…”

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

2016

Sarcopenia is an age-related health problem in general communities. Effective exercise programs against sarcopenia remain necessary for community-dwelling older people. In order to summarize the available knowledge on this subject, we collected English articles from a MED-LINE/Pubmed database examining the effects of exercise interventions on sarcopenia-related outcome measures in community-dwelling older people. When nine articles, including eight randomized controlled trials, were reviewed, most studies demonstrated significant improvements in some outcome measures. Indeed, a significant improvement in the muscle mass in one study, muscle strength in two studies and physical performance in two studies was reported among five studies using exercise (E) alone. A significant improvement in the muscle mass in two studies, muscle strength in one study and physical performance in two studies was also reported among four studies using exercise plus nutritional supplementation (EN). Notably, the EN studies appeared to have less extensive exercise interventions than the E studies. One EN study further exhibited significant improvements in all outcome measures. Collectively, exercise could be used as anti-sarcopenic strategies and nutritional interventions when combined with exercise might play a compensated or perhaps a comprehensive role among communitydwelling older people. Limited studies exist and more studies are required for the optimum programs in the community settings.

SummaryThis study aimed to demonstrate the beneficial effects of nutritional supplementation with dietary milk fat globule membrane (MFGM) on physical performance and skeletal muscle function in healthy adults aged 60 and over with semiweekly light exercise. The study was designed as a randomized double-blind controlled trial. Twenty-two Japanese participants (10 men, 12 women) aged 60-73 y were assigned to one of two groups (11 [5 men, 6 women] in each). One group received MFGM tablets (1 g MFGM/d), and the other received placebo tablets daily for 10 wk. Both groups participated in a twice-weekly light exercise program. Physical function tests and surface electromyography (EMG) were conducted at the baseline and after 5 and 10 wk. Chair stand time significantly shortened in both groups after 10 wk compared with that at the baseline. The average time shortened more considerably in the MFGM group than in the placebo group, although the change was not statistically significant. Both knee extension strength and the cross-sectional area of the quadriceps muscles significantly increased from baseline in the MFGM group but not in the placebo group. Surface EMG showed that muscle fiber conduction velocity increased significantly after 10 wk from the baseline only in the MFGM group. The increase from the baseline was significantly greater in the MFGM group than in the placebo group. Daily supplementation with MFGM increased motor unit action potential conduction and improved muscle strength and physical performance in healthy Japanese adults aged 60 y and over paired with semiweekly light exercise.

“…However, TUG, which is a physiological index of skeletal muscle function, was improved by catechin ingestion alone (p<0.05). Recently, catechin with exercise training was reported to have a beneficial effect on skeletal muscle function measured by TUG and skeletal muscle mass [29]. However, this is the first study showing that catechin-ingestion without exercise training could improve walking ability measured by TUG in healthy elderly women.…”
