Abstract

The elderly population has been dramatically increasing over the past years, but most of the population has developed chronic diseases and handicaps due to aging. High-intensity resistance training is one of the most effective ways to improve muscular strength, but it is unclear whether body composition and functional fitness would be increased by high-intensity resistance training. The aim of this investigation was to explore whether 12 weeks of high-intensity training would improve muscular strength, body composition, and functional fitness in women over the age of 70 years. Twenty-four participants were randomly assigned to a high-intensity resistance training group (n=8), a low-intensity resistance training group (n=8), and a control group (n=8). The experimental groups exercised 3 days per week for 12 weeks at a local fitness center. An analysis of variance(ANOVA) with repeated measures was used for analysis. The results showed that there was a significant improvement in agility and muscular strength following the high-intensity resistance training. Moreover, Moreover, %body fat and body fat mass decreased significantly after the 12 weeks of high-intensity resistance training(p<0.05). Based on these results, it was concluded that high-intensity resistance training is efficient for women over the age 70 years in increasing their muscular strength and functional fitness and reducing their total body fat mass.
