초록

이 연구의 목적은 고강도로 실시되는 12주간의 웨이트 트레이닝을 통하여 노인 여성들의 신체조성 및 기능적 체력에 어떠한 변화가 있는지를 규명하는 것이다. 연구대상자들은 U경로당에 정기적으로 출입하는 70세 이상 노인 여성 중에 실험의 취지를 알고 자발적 참여의사를 가진 24명을 선정하였다. 선정된 24명을 무선할당 방법을 통해 두 개의 운동집단인 고강도 저항성 운동 집단 (High intensity resistance group, n=8), 저강도 저항성 운동 집단(Low intensity resistance group, n=8) 그리고 비교군 (Control group, n=8)으로 나누었다. 운동집단은 12주간의 고강도 및 저강도 저항성 운동을 실시하였으며, 비교군은 12주간 어떠한 운동에도 참가하지 못하도록 제한하였다. 연구결과, 12주간 실시된 고강도 웨이트 트레이닝은 근력과 민첩성을 유의하게 향상시켰으며, 체지방률과 체지방량은 유의하게 감소시켰다(p<0.05). 평형성 및 심폐능력은 향상되었으나 통계적 유의성은 없었다. 종합해보면 정기적인 고강도 웨이트 트레이닝은 노인 여성들의 체력 개선에 도움을 줄 수 있는 운동이라 사료된다.

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.
