Glucose-fatty acid cycle is very important because it explains that fatty acid influences glucose level. Glucose-fatty acid cycle is the key factor to understand how endurance training which aids fat oxidation and carbohydrate stored in skeletal muscle influence mitochondria level. However, it is not certain whether glucose-fatty acid cycle influences exercising skeletal muscle of human being. As an energy resource, training increases use of fatty acid, endurance ability, and oxidation of triglyceride. During high level training, catecholamine secretions and restraint of fatty acid use caused by insulin increases dramatically, this results in reduction of free fat acids and reunification of free fat acids into triglyceride. Training restrains insulin activity and reduces plasma acid density, however, elite athletes have high triglyceride-fatty acid cycle. Although enzyme's activities and mitochondira's density increase after training, it's not certain that enzyme's activities is major factor in restraint of fatty acid oxidation in exercising muscle cells. Stores of fat leads to increases of fat oxidation, performance and reduces use of carbohydrate, however, there is no absolute evidence to support these results.

The purpose of this study was to investigate the effects of the aerobic exercise and resistance exercise program on the aerobic exercise capacity, ST segment depression and risk condition of cardiovascular disease in the obesity elderly women. Subjects were 10 elderly women, who aged 65~72 years old. Subjects were trained by the aerobic exercise and resistance exercise training program that was composed of the intensity of 40~60% HRmax, the duration of 30~40min, the frequency of 3~4d/w, and period of 12weeks. To analyze measured data, the paired t-test were completed with before and after complex training data. The conclusions of this study were as follows; 1. In aerobic exercise capaclty, after 12 weeks training, percent body fat, were decreased, body fluid were increased. Resting and recovery heart rate(HR) were decreased between before and after training. Resting and peak systolic blood pressure (SBP) were decreased between before and after training. Oxygen uptake(VO2) were increased between before itnd after training. Myocardial oxygen uptake(MVO2) were decreased between before and after training. In ST segment, ST Ievel were increased significantly, ST slope were decreased between before and aftcr training. 2. When ST/HR slope were compared with ST segment, the ischemic symptoms were apt to early diagnose in ST/HR slope. 3. Duke treadmill exercise score(DTS) were increased between before and after training. In conclusion, we could know that not only the regular training might increase or change almost the cardiovascular function variables for body composition, exercise capacity, and ST/HR slope between before and after training. Therefore, we might tell that training program could provide an excellent parameters for enforcing or keeping the cardiovascular function of elderly women

The effects of prolonged endurance training on maximal O₂ uptake in the older people and its determinants were studied, by comparing 1) 7 older endurance athletes(62.5±2.6yrs), 2) 7 middle-aged long distance runners(34.7±3.1yrs), 3) 7 older(61.3±3.8yrs) and 4) 7 middle-aged(33.7±3.1yrs) untrained counterparts, maximal O₂ uptake of the older athletes(50.4±4.1ml/㎏/min) was 67% higher than that of the older untrained men, 28% lower than that of the middle-aged runners, and identical to that of the middle-aged untrained men. The maximal heart rate was 9% lower in the older athletes than in the middle-aged runners(170 vs. 186beats/min). No significant difference in maximal heart rate was observed between the athletes and the nonathletes of the respective age-group. On the other hand, the O₂ pulse at maximal O₂ uptake of the older athletes(0.30±0.03ml/㎏/beats) was 14% lower than that of the middle-aged athletes, but 67 and 15% higher than that of the older and middle-aged untrained men, respectively untrained men, respectively. These results suggest that the lower maximal O₂ uptake of the older endurance athletes is derived from both the lower maximal heart rate and the lower O₂ pulse at maximal O₂ uptake in comparison with the middle-aged athletes.
