| ABSTRACT |
|
Increased arterial stiffness as an independent risk factor for cardiovascular disease, is increased in hypertensive patients. Regular aerobic exercise reduces arterial stiffness, while resistance exercise may increase arterial stiffness, but this is not a universal finding. The purpose of this study was to determine the impact of resistance exercise on arterial stiffness in untreated pre and hypertensive subjects. Twenty-one pre and hypertensive subjects(mean age 61±5 years) were randomly assigned to two group. Resistance exercise group(n=11) was performed the supervised resistance exercise program with light to moderate intensity(40~60% of 1 RM), 9 resistance exercises, 12 repetitions, 2sets, 3 times per week, for 12weeks. Control group(n=10) was maintained previous lifestyle. Muscle strength and carotid-femoral pulse wave velocity, an index of arterial stiffness, were measured at baseline and after intervention. Muscle strengthens were significantly increased in exercise group(p<.05). Systolic blood pressure and mean arterial pressure were significantly decreased in exercise group(p<.05). Carotid-femoral pulse wave velocity was significantly increased in exercise group(p<.05), but not control group. In conclusion, light to moderate intensity resistance exercise has negative effect on arterial stiffness in untreated pre and hypertensive subjects. |
