OBJECTIVE: To evaluate exercise intervention efficacy for the prevention and treatment of sarcopenia in the elderly. METHODS: We conducted a systematic literature search of randomized controlled trials in the Physical Activity Guidelines Advisory Committee Report (before 2007), Pubmed, the Cochrane database, and Igaku Chuo Zasshi (January 2006 to August 2009). DATA EXTRACTION: Two authors independently extracted relevant data. A total of 951 articles were found by search engines, and 9 studies were finally selected after a review by 2 experts. The content of these studies, especially duration, sets, periods, frequency, and intensity of exercise intervention were extracted and summarized in a results table. Five of 6 articles concluded that high-intensity resistance training significantly increased soft lean tissue and muscle mass. The remaining 3 articles indicated that moderate-intensity resistance training did not affect soft lean tissue or muscle mass. CONCLUSION: This systematic review suggested that high-intensity resistance training with sufficient periods, frequency, repetitions, and sets is effective to counteract the loss of muscle mass associated with advancing age.

Although resistance training (RT) combined with whole-body vibration (WBV) is becoming increasingly popular among untrained adults, the additional effects of WBV on muscle fitness are still not well understood. The aim of the present study was to evaluate the effects of WBV on muscle strength, muscle power, muscle endurance, and neuromuscular activities compared with the identical RT without WBV. Thirty-three individuals (6 males and 27 females; 22-49 years old) were randomly assigned to a training program using slow-velocity RT coupled with WBV (RT- WBV group, n = 17) or an identical exercise program without WBV (RT group, n = 16). Participants performed eight exercises per 60 min session on a vibration platform (RT-WBV group, frequency, 35 Hz; amplitude, 2 mm) twice weekly for seven weeks. To evaluate the effects of WBV, the maximal isometric and isokinetic knee extension strength, maximal isometric lumbar extension strength, countermovement-jump, and the number of sit-ups were measured before and after the trial. Significantly higher increases were observed in the maximal isometric and concentric knee extension strength (p = 0.02, p = 0.04 , respectively), and maximal isometric lumbar extension strength at 60 degrees of trunk flexion (p = 0.02) in the RT-WBV group (+36.8%, +38.4%, +26.4%, respectively) in comparison to the RT group (+16.5%, +12.8%, +14.3%, respectively). A significant difference was also observed between the RT-WBV group (+8.4%) and the RT group (+4.7%) in the countermovement jump height (p = 0.02). In conclusion, the results suggest that significant additional increases in maximal isometric and concentric knee extension and lumbar extension strength, and countermovement jump height can be achieved by incorporating WBV into a slow-velocity RT program during the initial stage of regular RT in untrained healthy adults. Key pointsA randomized controlled trial was conducted to investigate the effects of slow velocity resistance training combined with whole-body vibration on maximal muscle strength, power, muscle endurance, and neuromuscular activities in healthy untrained individuals.Resistance training program for lower extremities and trunk muscles were performed twice weekly for 7 weeks.A 7 weeks slow velocity resistance training program with whole-body vibration significantly increased maximal isometric knee extension and lumbar extension strength and power in healthy untrained individuals.

Resistance training with whole-body vibration (WBV) is becoming increasingly popular as an alternative to conventional resistance training or as supplementary training. Despite its growing popularity, the specific effects of WBV training on muscle morphology, strength, and endurance are not well understood, particularly in young adults. The aim of this study was to determine the effects of WBV training on bone-free lean body mass (BFLBM), and maximal muscle strength and endurance in healthy, untrained, young individuals. Eighteen healthy men and women (21-39 years) were randomly assigned to either a body-weight exercise with WBV (VT) group or a control exercise group without WBV (CON). Participants performed eight exercises per 40- min session on a vibration platform (VT group, frequency = 30-40 Hz; amplitude = 2 mm) twice weekly for 12 weeks. Anthropometry, total and regional BFLBM (trunks, legs, and arms) measured by dual- energy X-ray absorptiometry, and muscle strength and endurance measured by maximal isometric lumbar extension strength, maximal isokinetic knee extension and flexion strength, and the number of sit- ups performed were recorded and compared. Two-way repeated-measures ANOVA revealed no significant changes between the groups in any of the measured variables. We conclude that 12 weeks of body weight vibration exercise compared to body weight exercise alone does not provide meaningful changes to BFLBM or muscle performance in healthy young adults. Key pointsA randomized controlled trial was conducted to investigate the effects of body-weight exercise combined with whole-body vibration on bone-free lean body mass and maximal muscle strength and endurance in healthy young individuals.Body-weight exercises for lower extremities and trunk muscles were performed twice weekly for 12 weeks.Participants in the exercise with whole-body vibration group increased the vibration frequency from 30, 35, to 40 Hz at a constant amplitude of 2 mm during the trial.A 12-week body-weight exercise program with whole-body vibration did not significantly increase bone-free lean body mass in healthy young individuals, and no additional increases in maximal muscle strength and endurance were observed.

【アンチエイジングとリハビリテーション】運動とアンチエイジング

加齢に伴い、一般的に身体機能は低下する。定期的に体を動かすことが、健康的な加齢に好影響を及ぼすことが実証されている。心肺機能については、例えば最大酸素摂取量は、25歳以降10年で約10%低下する。活動量の多い人では減少が少なく、また高齢者でも、強度依存性にトレーニングにより増加しうる。筋力は60〜70歳代で10年間に約15%、それ以降では10年で約30%低下する。適切な負荷がかかれば、高齢者であっても筋力や筋量の増加が期待できる。日常のエネルギー消費量も加齢とともに低下するが、主たる原因は、加齢に伴う身体活動量の低下にある。定期的な身体活動や有酸素トレーニングにより、種々の生理機能・代謝指標・心理指標の改善を認めること、種々の慢性疾患や早期死亡のリスクを減少させることが、多くの実験的研究や疫学研究により幅広い年齢層で示されている。生涯の各時期で運動に取り組むことがアンチエイジングに寄与するといえよう。(著者抄録)
