Abstract

自体重を負荷にした低速度(各動作4秒間)の筋力トレーニングを毎日、12週間にわたって高齢者に実施した。種目はスクワット、腹筋、ボールつぶしの3種目。週のうち1日は教室に参加する対面方式で、残り6日間は自宅(非監視)で実施した。参加者は自立したT市在住の高齢者(65~85歳)44名。筋トレ実施群が26名(平均年齢70歳、男性13名、女性13名)。対照群が18名(平均年齢72歳、男性8名、女性10名)。2群は無作為ではなく、居住地区によって分けた。筋トレ実施群は12週間後に、体重、腹囲、空腹時血糖、HOMA-R(インスリン抵抗性)が有意に減少、HDLコレステロールが有意に増加した。一方の対照群はHbA1cの改善は認められたが、それ以外の項目で有意な変化は認められなかった。12週間という比較的短期間、かつ自体重を負荷にした筋力トレーニングであっても、各動作4秒間という低速度で実施することで、高齢者の形態、糖・脂質代謝を改善させうることが示唆された。This study examined the effect of a 12-week non-instrumental slow movement resistance training program using body weight as a load (RT-BW) on body composition and metabolic profiles in elderly people. Elderly volunteers (21 males and 23 females) aged 65-85 years were non-randomly divided into RT-BW (12 males and 20 females) and control (10 males and 10 females) groups. The RT-BW subjects were trained everyday for 12 weeks. We evaluated body weight and waist circumference, and measured serum lipid levels and HbA1c at baseline and after 12 weeks of training. Significant changes over 12 weeks were noted in the RT-BW group in the following measurements. As to anthropometric data, waist circumference and body weight were significantly decreased. There were significant increase in HDL cholesterol and decreases in fasting blood sugar, HbA1c and HOMA-R. In control group, only significant decrease was observed in HbA1c. Relatively short-term, non-instrumental slow movement resistance training using body weight as a load was effective in improving anthropometric and metabolic profiles in elderly people.
