영문 초록

Strength training is an effective method for developing musculoskeletal strength and is often prescribed for fitness, health, and the prevention and rehabilitation of orthopedic injuries. Strength training include increases in muscle mass, bone mass, and connective tissue thickness. The purpose of this study was to assess the cross-sectional area of thigh and cardiovascular improvement in elderly women following resistance training. 16 healthy women were recruited through local mewspaper. 8 dropped out before and during 8-week program. Pre-and post training measurements were obtained from 8 exercisers (mean age was 68.13±3.6cm ; ranged 65 to 75 years). All subjects were exercised 40 min ; the warm-up and cool-down phases lasted for a total of 20 min. During main exercise, subjects performed 20 min of weight training 3 times per week. Statistical evaluation of the data was accomplished using multivariate analysis. Statistical significance was accepted at p＜0.05. Following 8 weeks weight training program, there were significant difference (p＜0.021) in % body fat, cholesterol, and triglyceride. Resting HR and systolic, diastolic blood pressures were not significant (p＞0.169). but post-hoc analyses (stepdown F-test) indicated significant difference ; resting HR reduced 75.38±6.2 beats/min to 70.50±5.10 beats/min (6.5%), DBP 86.88±10.09mmHg to 76.75±9.25mmHg(8.2%), and SBP 160.00±13.68mmHg to 143.13±9.41mmHg(9.5%) after training. The cross-sectional area of thigh in elderly women were significant difference (p＜0.014) following 8-week strergth training.
