Evaluation on the effect of low intensity exercise training in coronary artery disease. Including the evaluation on significance of exercise training after CABG surgery / 体力科学

A study was conducted to evaluate the effects of exercise training for cardiac rehabilitation. 69 patients with coronary artery disease were assigned to a low intensity exercise training program, which lasted for 3 months. The target heart rate for the exercise program was set at 50-60% of maximal heart rate. For comparison, the study patients were divided into 2 groups. 25 patients who had undergone CABG were assigned to group A and 42 patients who had not undergone CABG were assigned to group B. A symptom-limited treadmill exercise test was performed before and after the exercise training program in each patient. Oxygen uptake (VO<SUB>2</SUB>), SBP, HR and PRP were measured at rest, submaximal workload and workload at the end point during the treadmill exercise test.<BR>In addition, FAT, LVI and PCI were calculated. The parameters measured before and after exercise training were compared in order to assess the effects of the exercise training program. Our findings showed that exercise training was effective for improving exercise tolerance and submaximal exercise capacity in patients with coronary artery disease, particularly those who had undergone CABG.

Exercise physical characteristics and laboratory findings in Japanese elite Judo athletes / 体力科学

A study was performed to evaluate the physical exercise characteristics of 29 Japanese elite judo athletes by treadmill exercise test. Functional aerobic impairment (FAI), heart rate impairment (HRI) and peripheral circulatory impairment (PCI) in the judo athletes were not significantly different from those of normal sedentary subjects. However, myocardial aerobic impairment (MAI) was lower than in normal sedentary subjects. %VO<SUB>2</SUB>max at the anaerobic threshold (AT) was 57.5±3.3% in male, and 57.0±4.3% in female judo athletes. %HRmax at AT was 72.4±3.8% in males, and 75.2±5.3% in females.<BR>These findings suggest that functional aerobic capacity and peripheral circulatory function in Japanese elite judo athletes are not significantly different from those of normal sedentary subjects, but that judo athletes have high left ventricular function.<BR>The blood biochemical profile and urinalysis date revealed that values of muscle injury enzymes, plasma uric acid and cholesterol were increased with relatively high freqency in elite judo athletes. Similar data were also obtained in individuals with suspected diabetic nephropathy and rhabdomyolysis.
