This study was undertaken to investigate effects of testosterone and growth hormone on exercised skeletal muscles. Ten Sprague - Dawley rats were daily trained with treadmill for 6 weeks as control. Another 20 rats were injected 3㎎/㎏ per week of testosterone and 0.2 unit per week of growth hormone respectively during exercise as same manner. The gastrocnemius muscles were observed by light microscopy and electron microscopy. In addition, enzyme histochemistry for ATP ase was performed to evaluate differences of muscluar hypertrophy between muscle types. In order to evaluate muscular hypertrophy, the areas of the muscle fibers cross sectioned were estimated by image analysis. Mean areas of cross sectioned muscle fibers were as follows: non-exercised control, 1020±22.7 μ㎡, exercised control, 1193±18.1 μ㎡, testosterone injected exercised group, 1418±28.4 μ㎡, and growth hormone injected exercised group. 1593±17.7 μ㎡. There was no difference in degree of muscluar hypertrophy between type Ⅰand type Ⅱ muscle fibers. On electron micoroscopy, increase of mitochondria in size and number appeared sequentially in growth hormone injected exercised group, testosterone injected exercised group, and exercised group. According to the above results, it is concluded that th testosterone and growth hormone enhance hypertrophy of skeletal muscle during exercise.

In this study, we compared and analyzed the differences in body composition, physical fitness and dribble skill between twenty two university soccer players and twenty non-athletes. Firstly, it was hypothesized that such a study would reveal some information on the physical condition level of university soccer players. Secondly, it was hypothesized that the differences are in accordance with the position (FW, LK, FB) played. Lastly, it is hoped that such a study will level contribute to the improvement of soccer players physical fitness as well as in soccer performance. 1. Body composition, physical fitness and skill (1) Absoulte lean body mass of soccer players is significantly higher that that of non-athletes(p〈0.01). (2) The agility, 1000M, 50M-dash, vertical jump, dynamic flexibility (power, agility, endurance) and dribble skills of soccer players are significantly different compared with these of non-athletes(p〈0.01). 2. Body composition, physical fitness and skill in accordance with the position. (1) There was no significant difference in the body composition of soccer players according to the position played. (2) The only thing in which significant differences were sech were in the 50M dash, and dynamic flexibility. In the 50M dash, there was significant difference between the performances of FW, and FB, LK and FB. In other words. FW and LK are faster than FB(p〈0.05) . In the case of dynamic flexibility (endurance), that of LK is significantly higher than that of FB(p〈0.05). (3) In the dribble test, there was a significant difference between FW and LK, FW and FB. So, the dribbing of FW is sxcellent among the soccer players(p〈0.05).

Background : Lipoprotein lipase(LPL) is a key enzyme in the metabolism of serum triglycerides(TG) which is utilized in the peripheral tissue as free fatty acid and stored in adipose tissue. LPL gene is consisted of 10 exons which encode 475 amino acids and over 9 LPL gene polymorphisms have been reported. It's polymorphisms are related to the lipid levels and the severity of atherosclerosis in the coronary artery disease. In Korea, LPL polymorphisms has not been reported yet. This study is purposed on the incidences of LPL gene mutations and on it's relationships with blood lipid levels and the severity of atherosclerosis. Methods : Our subjects were consisted of three groups, normal controls(n=50), coronary artery disease(CAD, n=51) and cerebrovascular disease(CVD, n=52). The PCR amplified genomic DNA from peripheral white blood cell were analyzed with restriction fragment length polymorphisms (RFLP by two different restriction enzyme(PVU II, Hind III). Results : Total cholesterol(TC) were higher in CVD than in controls and in CAD (203±60mg/ dl vs 188±37, 167±42, p<0.01). Triglyceride(TG) were also elevated in CAD(166±65mg/dl vs 122±62 in controls, p<0.05). HDL cholesterol(HDL-C) were higher in controls than in CVD and CAD(49±9mg/dl vs 36±10, 44±9, p<0.05). The incidences of Hind III RFLP and PVU II RFLP has no differences among groups. Only HDL-C was elevated in Hind III RFLP(-/-) homozygotes. Conclusions : The LPL gene mutations in intron 6 and 8 have no direct effects on the lipid profiles and the severity of coronary artery disease. Although LPL is a key enzyme in TG metabolism, two mutations in this study could not change the activity of LPL, nor were not a marker of linked other site mutations. The mutation(s) in exon which encode amino acid for enzyme activity should be detected to analyze the pathophysiology of the atherogenesis.

This study was carried out to investigate the ultrastructural changes of glycogen and ATPase activity of the cardiac and skeletal muscle fibers after exercises. Sprague-Dawley rats weighing 150gm ran on the treadmill in high intensity (21.6m/minute for 50minutes). Myocardium of left ventricle and triceps muscle were observed 0, 30, and 60minutes after exercise by light micros copy with hematoxylin-eosin stain and PAS stain and electron microscopy. Enzyme cytochemical electron microscopy for study the activity of ATP ase was poformed. The results were as follows. There were no significant different findings between control and exercised groups on he matoxylin-eosin stain. On PAS stain, positive activity was attanuated in the skeletal muscle 0 minute after exercise. On electron microscopy, both cardiac and skeletal muscle demonstrated significant decrease of amount of glycogen particles 0 minute after exercise. Glycogen restoration occurred promptly 30 minutes after exercise in both cardiac and skeletal muscle. There were no significant differences in the activity of ATPase in control and exercised groups. These findings suggest that glycogen consumption is mostly pronounced 0 minute after exercise in cardiac and skeletal muscle, and that restoration of glycogen may rapidly occur.

This study aims to identify the basic consciousness of the dancing troupe in terms of transmission of traditions in dance. As a result of the study, it is concluded that the act of transmission of traditions in dance presupposes the establishment of the dancing troupe's self identity and a sense of security. Transmission of traditions is accentuated and cherished by the dancing troupe in order to retain its identity as the foundation of a sense of security. However, no less important is the ceaseless efforts to make the liberal development of possible body motions and the creations of original forms of expressions. As in other fields of art, the dancing troupe must find its significance in close relation to the general public and in creative self-development.

The purpose of this study was to examine effects of different recoveries from high intensity short duration arm & leg exercise on lactate removal rate and second performance. 14 subjects completed 6 experimental sessions Each subject completed an initil all-out cranking and pedaling task with 5kg(pedaling)and 2kg(cranking)resistance(Monark bicycle ergometer) followed by a randomly assisted recovery pattern and a second high intensity exercise task The main effects examined were arm exercise recovery (0.3kg, 60rpm) vs leg exercise recovery(1.0kg, 60rpm) vs passiv recovery during recovery. pedal revolutions(second performance) were analyzed on a 10sec by sec and on a cumulative basis. The summary of results are as follows. 1. The blood lactate removal rate following supramaximal arm exercise was higher in arm exercise recovery than in leg exercise recovery and passive recovery(P<0.001). 2. The blood lactate removal rate following supramaximal leg exercise was higher in leg exercise recovery than in arm exercise recovery and passive recovery(p<0.001) . 3. Second performance following supramaximal arm exercise was higher in arm exercise recovery than in leg exercise recovery and passive recovery(p<0.001). 4. Second performance following supramaximal leg exercise was higher in leg exercise recovery than in arm exercise recovery and passive recovery(p<0.001) . Conclusively, in the aspect of blood lactate removal and second performance, it can be stated that alive recovery, especially with the same muscles that used in the exercise, is more effective than passive one.
