PURPOSE: The purpose of this study was to investigate whether a circuit aerobic exercise program positively affects pulmonary function and gait endurance in chronic stroke patients. METHODS: Twenty-four chronic stroke patients were allocated equally and randomly to an experimental group (n=12) or a control group (n=12). All participants received 60 minutes of comprehensive rehabilitation treatment, the experimental group additionally performed a circuit aerobic exercise for 30 minutes, while the control group additionally performed a general aerobic exercise, i.e., gait training on the treadmill for 30 minutes. These 30-minute exercise sessions were held three times per week for six weeks. Pulmonary function was assessed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV), and gait endurance was assessed using the 6-minute walk test (6MWT). RESULTS: In the both groups, FVC, FEV1, MVV, and 6MWT were significantly increased after training. Members of the experimental group showed significant improvements in FVC, FEV1, and MVV, and significantly greater improvements than controls (p<.05). However, 6MWT improvements were not significantly different in the two groups (p>.05). CONCLUSION: The devised circuit aerobic exercise program offers an effective rehabilitation aerobic exercise for improving pulmonary function and gait endurance in patients after chronic stroke.

The purpose of this study was to analyze the effect of a 12 week aerobic resistance training circuit program on the health-related fitness, blood lipids, and cortisol in obese postmenopausal women. The subjects for the study were twenty obese postmenopausal women composed of the exercise group (n=10) and "no exercise" control group (n=10). The aerobic resistance training circuit program was conducted for 70 minutes 3 times a week for 12 weeks, in which the aerobic exercise consisted of 5 items each composed of 5 sets of aerobic exercise at 50-70% HRmax intensity for 1 minute for a total of 25 minutes and the resistance exercise consisted of 8 items conducted for a total of 25 minutes at 40-60% intensity of 1RM). In the exercise group, the body weight and BMI significantly decreased and the 20m shuttle run, sit-ups and sitting trunk flexion significantly increased. In the exercise group, the TC, LDL-C, and TG significantly decreased. Also, it was noted that the HDL-C was slightly higher in the exercise group than in the control group, but the difference was not statistically significant. The cortisol levels of the exercise group and control group at baseline were similar. However, after the aerobic resistance training circuit program, the exercise group had a significantly higher cortisol level than the control group. Therefore, regular and continuous aerobic resistance training was effective in improving the body composition, blood lipids and health-related fitness.

This paper describes a compact and novel wireless vital sign sensor at 2.4 GHz that can detect heartbeat and respiration signals. The oscillator circuit incorporates a planar resonator, which functions as a series feedback element as well as a near-field radiator. The periodic movement of a human body during aerobic exercise could cause an input impedance variation of the radiator within near-field range. This variation results in a corresponding change in the oscillation frequency and this change has been utilized for the sensing of human vital signs. In addition, a surface acoustic wave (SAW) filter and power detector have been used to increase the system sensitivity and to transform the frequency variation into a voltage waveform. The experimental results show that the proposed sensor placed 20 mm away from a human body can detect the vital signs very accurately.
