游泳有助降血壓

美國的研究發現,六十歲以上的老先生老太太〈唉!再過不到十年,我就是其中一個了〉,如果每週游泳3-4次,每次45分鐘左右,血壓就可以降低。

原先整天都是靜態生活的人,只要游泳起來,血壓可以降低,生活會更健康。

其實只要有運動,對健康就有幫助。游泳對老先生老太太特別好,因為游泳時水的浮力可以減少脊椎和關節的傷害。

A low-impact form of physical activity, swimming is often suggested as a good way for older men and women to exercise. Hirofumi Tanaka, from the University of Texas (Texas, USA), and colleagues studied 43 men and women, average age of 60 years, with high blood pressure or pre-hypertension but were otherwise healthy at the study’s start, with an average systolic blood pressure of 131 mm Hg. For twelve weeks, each subject engaged in either supervised swimming sessions – three or four times a week, gradually working their way up to 45 minutes of swimming at a time, or learned relaxation exercises. At the end of the study period, the swimmers lowered their systolic blood pressure by an average of 9 points. No change was observed in the relaxation group. The researchers also tracked blood pressure change over a 24-hour period: on average, the swimming group had a 24-hour systolic blood pressure of 119 mm Hg — down from 128 mm Hg at the study’s start. The study authors conclude that: “swimming exercise elicits hypotensive effects and improvements in vascular function in previously sedentary older adults.”
