The Effects of a 12-week Community-based Fitness Training Program in Frail and Prefrail Older Adults
12週社區體適能介入對衰弱與衰弱前期高齡者之成效
摘要
Background: Frail or prefrail older adults have risks of falling, disability, hospitalization, and death. The effects of a fitness training program conducted in the community is unknown. The aims of this study were to investigate the effects of a 12-week community-based fitness program on functional fitness and weight in frail and prefrail older adults. Methods: A quasi-experimental design was conducted and older adults who met the frail or perfrail criteria were recruited. The participants were assigned to the intervention or control groups based the communities. The intervention group (n=49) received 2 hours of multiple components fitness training once a week for 12 consecutive weeks and the control group (n=26) maintained routine activities. Functional fitness tests including upper and lower body strength, upper and lower body flexibility, alternative aerobic test, dynamic balance/agility and static balance; and weight, body mass index (BMI), and waist circumstance were collected before and after the fitness training program. Results: After 12 weeks, compared with the control group, the intervention group had significant increases in weight (F=9.58, p=0.002) and BMI (F=6.03, p=0.004), but no improvement in functional fitness. Conclusions: The 12-week fitness training program included multiple components is effective for weight and BMI in frail and prefrail older adults in communities, but it needs more training for functional fitness.

目的：衰弱與衰弱前期的高齡者可能有跌倒、失能、住院與死亡的風險。但在社區執行相關運動介入對此族群的研究較少。本研究目的為探索12週社區體適能介入在衰弱與衰弱前期高齡者之體適能與身體組成之成效。方法：使用準實驗設計，招募符合衰弱或衰弱前期標準之高齡者，依據所在社區分為實驗組與控制組。實驗組（49人）接受每週一次兩小時共12週的整合式體適能介入；控制組（26人）僅接受例行性活動。在介入前後測量體適能包括上下肢肌力、上下肢柔軟度、持久耐力、動態與靜態平衡；以及身體組成包括體重、身體質量指數與腰圍。結果：12週後相較於對照組，實驗組體重（F=9.58, p=0.002）與身體質量指數（F=6.03, p=0.004）明顯增加，但體適能無顯著改善。結論：12週社區體適能介入能改善衰弱與衰弱前期高齡者的身體組成；但對於體適能的成效需要更多的時間或訓練。
