This research has been conducted to determine the effect that the visually handicapped’s participation in an aerobic exercise program has on cardiorespiratory function and arterial pulse wave. The subjects of this research were 20 people who have a 1st degree visual impairment. They recognized the purpose of this research and agreed to take part in it. After receiving agreements from their guardians, we divided them into an exercise group of 10 and a comparison group of 10 at random. The exercise group conducted a 50-70%HRmax treadmill exercise for 60 minutes a day, five times a week, for 12 weeks, including warm up and warm down exercises. We then conducted a two-way repeated ANOVA, which regards the period of exercise and the two groups as independent variables. The follow-up verification for exercise periods according to each group was carried out with a paired t-test. The statistical significance level was p<.05. The following are the results of this research. First, the weight and body fat of the experiment group after exercise show a meaningful reduction compared to before the exercise program (p<.05).Second, the VO2max, HRmax, and VEmax of the experiment group after exercise show a meaningful increase compared to before the exercise program (p<.05). Third, the arterial pulse wave of the experiment group after exercise display a meaningful increase compared to before the exercise program (p<.05). Fourth, the systolic blood pressure of the experiment group after exercise does not show a meaningful reduction compared to before the exercise program (p>.05). These results prove that the visually handicapped’s participation in an aerobic exercise program is effective in the improvement of their cardiorespiratory function, bloodstream circulation function and blood vessel function.

The purpose of this study is to investigate the risk factors of metabolic syndrome, cardiorespiratory fitness, knee isokinetic function, and os-teoarthritis index inpatients with knee osteoarthritis women. Subjects were divided into the exercise group (n=9, aged 60.89±5.06), and the control groups (n=8, aged 61.25±1.91). Aquatic exercise was performed for 12 weeks, 3 times a week, 60 min a day. The changes of metabolic syndrome risk factors, cardiorespiratory fitness, knee isokinetic func-tion, and WOMAC index (Western Ontario and McMaster University osteoarthritis index) were measured and analyzed at pre- and postex-ercise program for verifying exercise effectiveness. As a result, fasting blood glucose (P<0.05), glycosylated hemoglobin (P<0.01), and tri-glyceride (P<0.05) were significantly decreased in the risk factors of metabolic syndrome. The maximum oxygen uptake in cardiorespiratory fitness was not significantly different. The left and right extensor mus-cles of knee isokinetic function increased significantly (P<0.01, P<0.01, respectively). There was no significant difference in flexor muscles. Os-teoarthritis index was significantly improved in stiffness (P<0.01) and physical function (P<0.05). In conclusion, aquatic exercise can be re-garded as an effective exercise program for managing metabolic syn-drome risk factors, increasing muscle function, and improving osteoar-thritis index in patients with osteoarthritis of the knee.

Intro/Purpose: Aging is associated with progressive decreases in arterial health and function as well as overall fitness. It is crucial to prevent or reduce the negative effects of aging on vasculature and fitness components by implementing appropriate lifestyle interventions, such as exercise training. We examined the effects of a swimming (SWM) regimen on arterial stiffness (pulse wave velocity, PWV), blood pressure (BP), wave reflection (AIx), muscle strength and aerobic capacity in postmenopausal women with stage 2 hypertension. Methods: Using a parallel experimental design, participants were randomly assigned to either SWM (n=52) or non-exercising control group (n=48) for 20 weeks. Participants in the SWM group trained 3-4 days/week, progressing in duration from 25 to 45 min. Participants’ carotid to radial PWV (crPWV), BP, AIx, muscular strength and cardiorespiratory capacity were measured at baseline and after 20 weeks of their assigned intervention. Results: There was a significant group x time interaction (P<0.05) for crPWV, AIx, and systolic and diastolic BP, which significantly decreased (P<0.05); and strength and cardiorespiratory capacity, which significantly increased (P<0.05) following SWM compared to no changes in control. Conclusions: SWM led to reductions in arterial stiffness, wave reflection and BP while increasing strength and aerobic capacity in postmenopausal women with stage 2 hypertension. SWM may be an effective intervention in the prevention and treatment of age-related vascular complications as well as declines in muscle strength and cardiorespiratory capacity.
