Introduction Resistance training (RT) and nutritional supplementation seem to have beneficial effects on muscle properties and physical performance in older adults. However, the reported effects of specific RT programmes and supplementation prescriptions vary among studies. The present study aims to examine the acute and residual effects of RT and/or beta-hydroxy-beta-methylbutyrate (HMB) supplementation on muscle mass, muscle strength and physical performance in older women with reduced muscle mass. Methods and …

The aim of this study was to investigate the effects of a 12-week rehabilitation program on body composition, shoulder pain, and isokinetic internal/external torques of pitchers with impingement syndrome. A total of 30 pitchers were divided into 2 groups: experimental group (EG, n= 16) and control group (CG, n= 14). The rehabilitation program consisted of physical therapy, warm-up, work-out, and cool-down. As results, body weight and fat mass of EG were decreased whereas muscle mass of EG was significantly increased after the …

Background. More efficient clinical indexes are needed to identify older people most likely to present mobility impairments. The aim of the present study was to determine which handgrip strength (HS) indexes are clinically relevant to detect risk of mobility limitation in the elderly …

Objectives To identify the dietary patterns among community-dwelling Japanese older adults and to explore the association between these patterns and sarcopenia. Design Cross-sectional study. Setting Kashiwa city, Chiba prefecture, Japan. Participants Community-dwelling older adults (n= 1241) aged 65 years and over who were not eligible for long-term care. Measurements Dietary intake was assessed using the brief self-administered diet history questionnaire (BDHQ). Dietary patterns were identified using both principal …

Aim Calf circumference (CC) measurement has been used for assessing skeletal muscle mass and for screening sarcopenia. However, there is no gold standard method for CC assessment. Methods We analyzed 1439 participants (mean age 75.9±3.8 years, 47.7% men) from the 2017 baseline survey of the Korean Frailty and Aging Cohort Study. CC was measured, using a tape, on both sides in standing and sitting positions. For sarcopenia, the diagnostic criteria of the Asian Working Group for Sarcopenia 2019 was used. Results The …

OBJECTIVE: Sarcopenia progresses with aging, but the effect of muscle loss on degenerative joint disorders has not been precisely evaluated. We assessed the distribution of lean body mass (LBM) in middle aged women who had osteoarthritis (OA) of the knee for< 5 years. METHODS: Two hundred thirty-five Japanese women aged 45-69 years, including 117 with knee OA for< 5 years, and 118 age and sex matched healthy controls were studied. Body composition measurements were carried out by segmental bioelectrical impedance …

Sarcopenia is associated with increased mortality among older adults. Sleep-related problems have been studied as factors related to sarcopenia. This study was conducted to determine the relationship between sleep-related problems and sarcopenia among Japanese community-dwelling older adults using data from the Nagasaki Islands Study. This cross-sectional study analyzed data collected from 2017 to 2018. A total of 1592 older adults (575 men, 36.1%) aged 65 years or older participated. Sarcopenia was evaluated using the …
