초록

본 연구는 24명의 노년기 아쿠아로빅스 회원들을대상으로 아쿠아로빅스와 하지근력강화 운동을 12 주간 지속한 집단(n=12)과 아쿠아로빅스 운동만을12주간 지속한 집단(n=12)의 신체구성과 평형성 그리고 슬관절 등속성 근기능 요인에 미치는 영향에대해 비교분석하였다.
그 결과, 첫째, 아쿠아로빅스와 하지근력 운동을복합적으로 실시한 실험집단에서 신체구성 변인 중골격근량 요인에서 통계적으로 유의한 차이를 나타냈으며, 둘째, 체력요인을 집단간 비교 분석한 결과하지근력운동을 12주간 실시한 집단이 근력, 근지구력, 민첩성 능력에서 유의한 향상을 가져온 것으로나타났다. 셋째, 하지 등속성 근기능 요인에서는 슬관절 신전시 등속성 근력 및 근지구력 요인에서 유의한 향상이 나타났다.
결론적으로 아쿠아로빅스 운동이 전반적인 체력향상에 긍정적인 변화를 가져오지만 수중에서의 부력으로 인해 하지근육의 발달을 위해서는 하지근력강화운동프로그램을 병행하는 것이 노인여성의 하지근지구력과 부분적인 체력에 도움을 주는 것을알 수 있었다.

The purpose of this study was to investigate the effect of lower extremity strengthening on exercise that body composition, physical fitness and isokinetic muscle function in the elderly female aquarobics. The subjects were 24 elderly women, who randomly assigned to one of lower extremity strengthening exercise(12) and the control group(12) of the experiment. The participants of intervention programs did exercise 60 minute per day, 3 trials per a week, during 12 weeks. They responded to body composition, physical fitness and isokinetic muscle function before this and after completing exercise intervention. The collected data were analyzed using independent t-test and paired t-test go through SPSS 23.0 version. The results were as follows : First, the post-test data onto body composition factor(skeletal muscle mass) had higher than pre-test similar to that of post-test in the control group. Second, the post-test data onto physical fitness factor(strength, muscular endurance, reaction time) had higher than pre-test score in the exercise intervention group of lower extremity strengthening exercise. But, the score of pre-test was similar to that of post-test in the control group.
Third, the post-test data onto isokinetic muscle function factor(peak torque & total work in 60˚, 240˚ extensors) had higher than pre-test scores / scored in the exercise intervention group of lower extremity strengthening exercise. But, the score of pre-test was similar to that of post-test in the control group. Finally, there were significant positive correlations between strength, muscular endurance, reaction time ability and isokinetic muscular strength and endurance. Especially, correlations coefficient of post-test had lower than that of pre-test in the intervention group. One the other hand, correlations coefficient of pre-test and post-test was relatively stable in the control group.
In total, these results mean that lower extremity muscles strengthening exercise are an effective intervention program in terms of enhancing physical fitness and lower extremity strength in the elderly female aquarobics.
