The purpose of this study is to investigate the further direction of molecular biological studies, the advantages and limitations of assaying samples, and variables in figuring out the details of domestic and overseas studies verified through cell and molecular biological analysis in order to analyze the effect of concurrent training. The analysis study was limited to domestic and overseas literature, which investigated the effect of combined training using molecular biological analysis among studies to date. The study was reclassified by specialty, composed of professors of physical education and doctors of exercise physiology. The final selected study analyzed the subject and the trend of studies in terms of comprehensive perspectives. In detail, it analyzed hormonal and enzymatic changes in criteria such as leptin, 5-HT, ACTH(adrenocorticotropic hormone), cortisol, testosterone, GH(growth hormone), LDH(lactate dehydrogenase), CPK(creatine phosphokinase), antioxidants in blood samples and protein, and enzymatic and morphologic changes in for CRP, VEGF(vascular endothelial growth factor), PAI-1(plasminogen activator inhibitor-1), MAD(malondialdehyde), carnosin, and SDH(succinate dehydrogenase), the area of muscle fibers, ratio of type Ⅰ/Ⅱ muscle fiber and capillary proportion per muscle fiber in the extracted muscle by biopsy, for example. Finally, urine samples, and hormonal changes (like cortisol), were analyzed. The results of the analysis of domestic and overseas studies according to combined training has shown that this training has more varied effects than single training and lower improvement by interference effect or magnifying the effect of one type of training amongst the combined training types appears, rather than higher improvement through combined trainings. Therefore, it should be investigated in view of performance improvements relating to the characteristic of sports.
PURPOSE The aim of this study was to investigate the effects of 12-week instrumental pilates exercise on isokinetic muscle function and body composition of healthy college women. METHODS Twenty-four college women (aged 21.6±1.3yrs) were recruited to the study. The participants were divided into two groups, as the instrumental pilates group (IPG, n=12) and the control group (CG, n=12). The springboard pilates exercise was conducted 3 times a week for 40~60 minutes during 12 weeks. RESULTS There was significant interaction effects in the right knee and left · right elbow extensor muscles (60°/sec) and left knee flexor and right elbow extensor · flexor muscles (180°/sec)(p<.05, p<.01). There was no significant interaction effects in the muscle mass of the total body, trunk, arms, and legs (NS) and also in the serum growth hormone, insulin-like growth factor-I and 25(OH)Vitamin D (NS). Serum creatine kinase was significantly increased (p<.05). There was also no significant interaction effects in weight, body fat, serum total cholesterol, triglycerides, low & high-density lipoprotein cholesterol (NS). CONCLUSIONS These results suggest that although prolonged instrumental pilates exercise of healthy college women might be improving isokinetic muscle function, there is no increasing effect of muscle mass.
