        운동생리학 : 저항성 및 평형성 운동이 낙상 경험 여성 노인의 보행형태에 미치는 영향

        최상웅(SangWoongChoi),이재상(JeaSangLee),구현정(HyunJoungKu),이대택(DaeTaekLee) 한국체육학회 2005 한국체육학회지 Vol.44 No.1

        This study examined the effects of resistive and balance training on walking patterns in the elderly women who experienced falls. A total of 40 women were recruited for the study, and they were randomly divided into two groups, one for exercise group (EG; 72 yrs, 151 ㎝, 58 ㎏, 25.2 ㎏/㎡ at baseline) and the other one for control group (CG; 72 yrs, 151 ㎝, 56 ㎏, 24.5 ㎏/㎡ at baseline). EG exercised 70 min/session, at least 2 times/week for 10 weeks using elastic bands and balance stabilizer while not for CG. Subjects in EG exercised for major muscle groups including chest, shoulder, upper arm, lower back, thigh, calf, and ankle. After the program, the balance test with one-leg-stand showed improvement in EG and it was higher than CG. The stride length was also longer after the program in EG (41 ㎝ vs 46 ㎝ in pre vs post, respectively), and the stride length was greater in EG than CG (34 ㎝) after the program. Differences of left and right foot distances when either foot was in front were reduced in EG after the program. Based on the results, the walking patterns were changed by the lower limb muscular strength and stability training. It is expected this change may contribute in reducing falls.

        자연과학편 : 요추환자의 척추 수술후 저항성운동이 근육관련 호르몬, 염증반응, 근력 및 가동범위에 미치는 영향

        이상철(SangChulLee),조지훈(JiHoonCho),최상웅(SangWoongChoi),이대택(DaeTaekLee) 한국체육학회 2007 한국체육학회지 Vol.46 No.3

        본 연구의 목적은 360。척추고정술 직후 초기 저항성 운동이 근육관련 호르몬, 염증변인, 근력, 관절가동범위에 어떠한 영향을 끼치는지 규명하여 수술후 환자의 운동치료 효과를 알아보는데 있다. 피험자는 360° 척추고정수술을 받은 환자 10명(운동그룹 5, 비운동그룹 5)을 대상으로 수술전, 수술후 3일, 퇴원당일 총 3회에 걸쳐 혈액검사, 근력 및 관절가동범위 측정하였으며, 수술후 3일째부터 저항성 운동을 실행하였다. 연구결과 근육관련 호르몬인 성장호르몬과 테스토스테론은 운동 그룹이 비운동그룹보다 감소의 폭이 작았으나 테스토스테론에 대해서는 운동군과 비운동군간에 유의차는 나지 않았다. 염증변인인 CRP는 운동그룹에서 비운동그룹보다 빠른 감소를 나타냈으며, ESR은 운동그룹이 비운동그룹에 비해 낮은 증가를 보였다 근력은 비운동그룹 보다 운동그룹에서 최대 굴곡 및 신전근력이 향상되는 경향을 보였으며, 최대 굴곡 및 신전 관절가동범위도 운동그룹에서 향상되는 것으로 나타났다. To determine the effect of postoperative resistance training on growth hormone (GH), Testosterone, C-reactive protein(CRP), Muscular Strength and range of motion(ROM) after lumbar surgery. They were tested 3 time; pre-surgery (pre-S), 3 days (3d-S), and 2 weeks after surgery (2w-S). At pre-S GH was 0.36+0.19 in EG and 0.24±0.19 ng/ml in CG, but was elevated in both groups at 3d-S. GH at 2w-S remained elevated in EG but did not in CG. At pre-S Testosterone was 0.16±0.17 in EG and 0.16±0.10 ng/ml in CG, but was elevated in both groups at 3d-S. Testosterone at 2w-S remained elevated in EG but did not in CG. CRP at pre-S was 0.18+0.18 in EG and 0.19+0.12 m/dl in CG. It was elevated in both groups in EG and 1.82±0.60 in CG) at 3d-S. At 2w-S CRP returned to the baseline in EG while remained elevated in CG. ESR was 6.8±2.4 and 8.0±3.4 at pre-S, and 9.3±2.3 and 11.0±5.9 mm/h at 3d-S in EG and CG, respectively. ESR at 2w-S was highly elevated in CG than in EG. At 2w-S, ROM for lumbar and estensor in EG was returned to the level of pre-S, but ROM for both flexor and extensor in CG was not. LFS was 128±22 in EG and 124±8 lbs in CG at pre-S, and it was decreased in both groups at 3d-S. At 2w-S, LFS was elevated in EG but was remained suppressed in CG.
