[Purpose] we aim to examine whether adding exercise has impact on obesity prevention and bone metabolism in senior rats, to which dietary obesity was induced through skim milk intake. [Methods] We used 47, 14-week old Sprague -Dawley (SD) female rats (CLEA Japan, Inc.). The Rats were separated into four random groups: 1) a Non-Ex group with a normal diet (n = 12), 2) an Ex group with a normal diet (n = 12), 3) a Non-Ex group with a skim milk diet (n = 11), and 4) an Ex group with a skim milk diet (n = 12). As the exercise for each Ex group, rats ran on a treadmill starting at 27-week old (TREADMILL CONTROL LE8710 and TREADMILL CONTROL LE8700, Harvard Bioscience). Training protocol stipulated a frequency of five times a week for 12 weeks. [Results] The leptin concentration differed with dietary content: compared to the Ex group with a skim milk diet, Non-Ex and Ex groups with a normal diet showed significantly higher values (p < 0.05). The Ex group had significantly lower values in both the normal diet and skim milk diet groups with or without exercise (p < 0.05).Compared to the Non-Ex group with a normal diet, BS/BV (mm2/mm3), BV/TV (%), Tb.Th (μm), TBPf (/mm) and Tb.N (/mm) had significantly lower in the Ex group, the Ex and Non-Ex groups with a whey protein diet, and the Ex group with a skim milk protein diet (p < 0.05). [Conclusion] These findings suggest that senior female rats fed SMP would have higher bone structural and strength parameters than rats fed a normal diet.

[Purpose] This study was performed to assess the effects of high-intensity intermittent swimming training(HIT) on bone in ovariectomized rats. [Methods] Six-week-old female Sprague- Dawley rats were randomly assigned to either sham operation or bilateral ovariectomy. After surgery, they were divided into the following four groups: 1) sham-operated sedentary (S), 2) sham-operated exercise training (SE), 3) OVX sedentary (O), 4) OVX exercise training (OE) 5) OVX given 17β-estradiol (OE2) and 6) OVX exercise training and given 17β-estradiol (OEE). SE, OE and OEE rats were used extremely high-intensity swim exercise. The rats repeated fourteen 20-s swimming bouts with a weight equivalent to 14, 15, and 16% of body weight for the first 5, the next 9, and the last 5 days, respectively. Between exercise bouts, a 10-s pause was allowed. HIT was originally designed as an exercise method; a method that very quickly induces an increase in the maximum oxygen intake (Tabata I et al., 1996). OEE and OE2 rats were subcutaneously injected ethanol with 25μg/kg body weight 17β-estradiol 3 times per week. [Results] Bone strength, bone mineral density and trabecular bone parameters were measured after a 8-weeks experimental period. Bone strength was significantly higher in the SE, OE, OE2 and OEE group compared with the O group. BV/TV was significant increase in the SE, OE groups compared with the O group. BMD showed no difference in the OE group compared with the O group. [Conclusion] This study demonstrate some beneficial effects of postmenopausal osteoporosis of high-intensity intermittent swimming training on bone structure and strength.

This study was examined the effects of deepsea water (DSW) supplementation and swimming exercise on bone metabolism in growing male rats. Thirty-two Sprague-Dawley male rats, 6 weeks of age, were randomly divided into high-fat diet sedentary (HS, n=8) or exercised group (HE, n=8) and DSW supplemented sedentary (DS,n=8) or exercised group (DE, n=8), given a high fat diet to all groups for 8 weeks. In the results, serum osteocalcin level of the DS was significantly lower than that of the HS (p<0.01). In addition, femoral bone mineral density (BMD), tibial bone mineral content (BMC), and breaking force of the DS were significantly higher than that of the HS (p<0.05). Furthermore, femoral BMD and tibial weight of DE were significantly higher than that of the HE (p<0.05). These results suggest that drinking deep-sea water and exercise has a crucial role for prevent osteoporosis and increase peak bone mass in growing male rats.

This study was designed to clarify the effects of red-rice bran extract administration and running training on bone and lipid metabolism in growing rats. Twenty-four 5-week-old male Wister- Kyoto (WKY) rats were randomly divided into four groups: Control Non-exercise group (CN; n = 5), Control Exercise group (CE; n = 4), Red-rice administrated Non-exercise group (RN; n = 5), Red-rice administrated Exercise group (RE; n = 5). The RN and RE groups were fed a standard diet (CE-2, Oriental yeast, Japan) containing 10% red-rice bran extract, the CN and CE groups were fed only a standard diet. Exercise was performed on the treadmill (KN-73, Natsume, Japan) at 23 m/min, 60 min/day, 5days/ week for 8weeks. At the end of the experimental period, rats were sacrificed with blood drawn and then tibia and several organs were removed. The serum T-cho, T-lipid and phospholipid of RN group was 45.5%, 37.0%, 40.2%, respectively lower than those of CN group (p<0.001) with a tendency of decrease in the body weight. The results of examination of the hapatic function, such as serum GOT, GPT, γ-GTP. TP, Alb, and the nephric function, such as BUN, Na, K, showed similar levels among groups. The bone mineral density (BMD) and content (BMC) of the CN and RN showed similar levels. On the other hand, although running exercise in CE group increased BMC compared with that of CN group (p<0.05), the exercise also increased body weight (p<0.01), heart weight (p<0.05), BMD (p<0.05) and BMC (p<0.001) in RE group compared with that of RN group. These results suggest that 8-week red-rice bran extract administration might improve the lipid metabolism, and the combined treatment with running training has more beneficial effects in body weight and BMD in growing rats.

본 연구는 66.89(±3.61)세 이상 여성 고령자 제1기 고혈압(JNC-Ⅶ)환자 9명을 대상으로 12주간 규칙적인 복합운동프로그램이 혈압ㆍ심혈관질환 위험 요소 및 혈색소에 어떠한 영향을 미치는지 연구하였으며, 운동프로그램은 복합운동프로그램으로 유산소운동으로 주3회 30분씩, 40~60%HRR의 운동 강도로 에어로빅스댄스 운동과 저항성운동으로 주3회 20분씩 1RM40∼50%운동 강도로 1∼3세트, 15∼25회의 덤벨운동을 실시하였으며 준비운동과 정리운동으로 스트레칭을 운동전ㆍ후 10분씩 12주간 동안 폴라(polar)를 착용하여 실시하였다. 선행연구와 비교 분석하여 다음과 같은 결론을 얻었다. 혈압의 변화에서는 SBP는 운동전ㆍ후13.03%감소하여 유의한 차이는 나타냈다(p<.05). DBP에서는 운동전ㆍ후 6.35%감소하였으나 유의한 차이는 나타나지 않았다. 또한 TC와 TG의 변화에서는 운동전 4.28%, 23.87% 감소, HDL-C와 LDL-C의 변화는 0.18%, 2.57%증가, RBC, Hemoglobin, Hematocrit의 변화에서는 0.05%, 0.09%, 0.43%증가하였으며 모두 유의한 차이를 나타내지 않았다. 이상을 종합하면 12주간의 복합운동 프로그램이 고령여성 제1기 고혈압질환자의 혈압ㆍ심혈관질환 위험 요소 및 혈색소에 긍정적인 영향을 미친 것으로 사료되며 따라서 고령자들의 혈액의 생화학적 요인 중 고형성분에 긍정적인 변화를 가져오기 위해서는 선행연구의 결과를 토대로 다양한 운동프로그램과 운동강도 등을 세분화하여 고령자들의 체력 특성에 맞는 규칙적이고 지속적인 운동프로그램 개발에 대한 연구의 다각적 접근이 필요하다고 사료된다.
