Obesity is frequently associated with metabolic disease. This study showed whether fenofibrate, a hypolipidemic agent, swimming and swimming combined with fenofibrate (: combination) regulate obesity, and whether combination is more effective than fenofibrate on regulation of obesity in high-fat diet-fed mice for 8 weeks. Both fenofibrate and swimming decreased obesity-associated factors such as body weight, adipose tissue mass, serum lipid levels and adipoctye size, compared with control mice. When mice were concomitantly treated with fenofibrate and swimming, combination reduced further the inhibitory effects on obesity-associated factors, compared with fenofibrate. Both fenofibrate, swimming and combination decreased serum glucose levels, compared with control mice. The evidence is presented herein that combination were effective to control obesity and serum glucose levels, suggesting that swimming combined with fenofibrate might contribute to inhibition of high-fat diet fed-induced metabolic syndrome.

본 연구는 인삼 사포닌(Ponax ginseng C.A. Meyer)이 수영운동을 부하시킨 웅성 횐쥐(Sprague-Dawley 계, 360 $\pm$ 40 9)의 대퇴근 크레아틴 키나제(Creative Kinase, CK: E.C. 2.7.3.2) 동위효소 활성에 미치는 영향을 연구하였다. 운동군은 3시간 동안 수영운동시켰으며 ,인삼군은 인삼 사포닌을 체중 Kg 당 120 mg 복강투여하였다. 인삼 사포닌을 투여한 운동군은 수영운동 1시간 전에 인삼 사포닌을 투여한 후 3시간 동안 수영시켰다. 인삼군의 MB-CK의 활성은 대조군보다 유의하게 증가하였다(P<0.01). 또한 인삼 비투여 운동군과 인삼 투여 운동군에서의 MM-CK활성은 대조군보다 각각 현저하게 증가하였고(P < 0.01와 P < 0.05), 특히 인삼 투여 운동군에서 BB-CK활성이 대조군보다 유의하게 증가하였다(P < 0.01). 인삼 사포닌은 일반적으로 CK-동위효소의 활성을 증가시키고, 운동은 MM-CK의 활성을 현저하게 증가시켰으며, 인삼 투여 운동군에서 BB-CK의 활성이 인삼 비투여 운동군보다 현저하게 증가하였다. 따라서 인삼 사포닌과 운동이 CK동위효소 활성에 상승의 효과를 나타내는 것으로 생각된다.

물을 매개로 운동하는 수영은 체력수준에 상관없이 남녀노소 모두 도전할 수 있는 운동이다. 수영은 심폐기능을 증진시키고 전신을 골고루 발달시킬 수 있을 뿐 아니라 비만 예방 및 허리 통증에도 효과적이다. 물에 대한 공포심만 없애면 누구나 도전할 수 있다. 더운 여름, 물살을 가르는 수영에 도전해보자.

The kinematic variables for swimming and fin-swimming start motions were analyzed and compared using 3-dimensional cinematography. For the swimming start, the arm segment moved towards the upper rear and trunk towards the upper front followed by a descent towards the lower front, while the fin-swimming start motion showed movement towards the lower front for all segments. The total body center of gravity for the swimming start showed horizontal movement far to the front followed by a rapid descent while the fin-swimming start showed close movement towards the lower front in a short period of time. Upon entering the water, the center of gravity for swimming showed high vertical velocities while fin swimming had high horizontal velocities. For both swimming and fin swimming, the upper extremity velocity had more influence on the total center of gravity velocity than the lower extremities. Flexion of the hip joint was observed before the jump for the fin swimming start while the swimming start showed two flexions in mid-air succeeding the jump. The flexion and extension movements at the knee joint during the fin-swimming start motion were shown to be larger and more rapid than those of fin-swimming.

본 연구는 마우스에 있어 규칙적인 수영훈련과 비타민 C 섭취가 운동스트레스를 부여하였을 때 항산화체계에 미치는 영향을 보고자 하였다. 수영훈련은 6주령의 Balb/c 마우스를 분양받아 1주간의 환경적응과 1주간의 수영적응 훈련을 (30 min/day) (5d/week) 실시하여 적응 여부를 가려 8주간의 본 수영훈련을 실시하였다(1 h/day) (5d/week). 실험군은 통제군(control: C), 수영훈련시킨 군(training: T), 수영훈련과 비타민 C를 투여한 군(training ＋ vitamin C (1.3 g/100 g diet) : TC}으로 나누었다.(중략)

This study investigated the effect of swimming exercise on inflammation in non-alcoholic fatty liver using animal models of postmenopausal obese women. Experimental animals were divided into a sham-operate + non-swimming trained group (S/N), an ovariectomize + non-swimming trained group (O/N) and an ovariectomize + swimming trained group (O/S), and were bred while eating a high fat diet for 8 weeks. Fat accumulation in liver tissue, liver weight, and serum AST and ALT increased in O/N compared to S/N, but decreased in O/S compared to O/N. Compared to S/N, O/N decreased the gene expression of IκBα in liver tissue and increased gene expression of MCP-1, IL-6, and TNF-α. But compared to O/N, O/S increased the gene expression of IκBα in liver tissue and decreased gene expression of MCP-1, IL-6, and TNF-α. In conclusion, this study suggested that swimming exercise was effective in improving physical health by improving inflammation in non-alcoholic fatty liver in obese mice induced obesity by high fat diet after ovariectomy.

This study investigated whether swimming exercises improves obesity through regulation of angiogenesis in white adipose tissue. Female mice with high-fat diets were divided into sham-operated group (Sham), ovariectomized group (OVX), and swim-trained ovariectomized group (OVX + Swim). Compared to the Sham, OVX increased body weight, adipose tissue mass and size of adipocyte. However, these factors (: such as body weight, adipose tissue mass and size of adipocyte) of OVX + Swim decreased compared with OVX. Compared with the Sham, OVX increased the mRNA expression of angiogenic activator and MMPs and decreased the mRNA expression of angiogenic inhibitors in white adipose tissue. But OVX + Swim decreased the mRNA expression of angiogenic activator and MMPs and increased the mRNA expression of angiogenic inhibitors in white adipose tissue, compared with the OVX. Theses results suggested that swimming exercises the angiogenesis in white adipose tissue, resulting to improve obesity in high-fat diet-fed female OVX mice.

This study is to examine the effect of swimming exercise on the expression of c-fos, c-jun protein in rat hippocampus. 4-weeks aged rats and 16-weeks aged rats were used in experimental materials. All of two groups were classified into control and swimming exercise group. Swimming exercise was practiced for an hour a day. The results were got as follows after practical application in 1 day, 3days, 7 days. The expression of c-fos, c-jun protein was increased in all of the two experimental groups significantly in 1 day, 3days, 7 days. It was increased gradually in order of after 1 day, 3days, 7 days. There seems to be the effect of swimming exercise increasing the expression of c-fos, c-jun protein in hippocampus. Therefore swimming exercise can improve cognitive function such as learning and memory and prevent through activating immediate - early gene by swimming exercise. And it seems to have the positive effect on growth and recovery of nerve.

This study was designed to investigate the effects of swimming and minocycline on motor function recovery and Bcl-2 expression after spinal cord injury (SCI) in rats. After operation, neurological motor behavior test (BBB scale) on days 1, 4, 7, 10, and 14 were tested. Western blot and immunohistochemical assessment (Bcl-2) were performed on day 14. BBB scale started to show a statistically significant difference on day 7 (p<0.05). On day 14, it showed the most significant (p<0.05) difference. Expression of Bcl-2 increased in all the experimental groups. In particular, the highest expression of Bcl-2 appeared in the swimming and minocycline groups. Based on these results, minocycline and swimming were the most effective factors in the motor behavior function and immunohistochemical assessment of SCI rats.
