장기간 저항운동이 골감소증 노인여성의 신체조성, 체력 및 골밀도에 미치는 영향 : 3년간의 증례보고

Abstract

This case study evaluated the long-term effects of resistance training (RT) on body composition, physical fitness and bone mineral density (BMD) in a osteopenia elderly woman.] The subject was a 65-yearelderly woman (lumbar BMD:–2.4g/cm2, height: 155.5 cm, weight: 59.1 kg, body fat: 28.2%, muscle mass: 23.5 kg). In January 2014, She was diagnosed with osteopenia and overweight. The chest, back and lower extremity were performed 60~75% of 1RM, and the core was used for the maximum number of repetitions, and the subject completed 12~20 times, 3 sets, rest times 1-min between sets and 3-min between exercise, and a total of 60-min per day included warm-up 10-min, resistance training 40-min and cool-down 10-min, 2~3 times per week, and for 3 years from January 2014 to January 2017. Body composition (weight, muscle mass, body fat and BMI), physical fitness (hand grip strength, sit-up, sit & reach and standing on one leg with eyes closed) and BMD (lumbar and neck of femur) were measured to 6 month interval and total 7 times. Body fat and muscle mass showed an change at after 6 months RT, and after 12 months RT, BMI increased compared to at before RT. Hand grip strength, sit-up, sit & reach and standing on one leg with eyes closed showed progressively increase at after 6 months RT compared to at before RT. BMD in lumbar showed progressively increase at after 6 months RT compared to at before RT, and BMD in neck of femur showed continually maintain at after 6 months RT compared to at before RT. In our case, long-term resistance training positively effects body composition, physical fitness and BMD in a osteopenia elderly woman, and suggested that physical fitness and BMD may be improved by early change to lower body fat and increased muscle mass.
