Unit 108 游泳運動
One of the best all-around exercises,swimming increases both cardiovascular and muscle strength.There is hardly any stress on your body's joints,because water turns you into a kind of weightless underwater astronaut,making your every movement an easy,flowing one,But water also offers resistance that helps you build muscle strength and tone.
游泳能促進心血管及肌肉的耐力,是最佳的全身運動之一。游泳時你全身的關(guān)節(jié)幾乎沒有任何的壓力,因為水使你變得好像是一個處于無重力狀態(tài)的水底航天員,使你的每個動作輕松又流暢。但水提供的阻力也會幫助你強化肌肉使其結(jié)實有力。
Doing laps in a pool-no matter what the stroke-is excellent exercise.You can also "take a walk"underwater or perform calisthennics like leg lifts or arm circles.Research shows that water actually offers an equal aerobic workout in less time than one on dry land.A half-hour of walking in water equals the energy output of a two-hour walk in the woods,one study showed.Make sure you're about chest deep(to benefit from the resistance)and simply go for a stroll.
不管你用什么姿勢游泳,在泳池里來來回回的游都是絕佳的運動。你也可以在水底“散步”或做抬腿或轉(zhuǎn)手臂的體操。研究顯示,在水里做有氧運動能以較少時間達(dá)到在陸上做的同稱效果。某研究顯示,在水里走上半小時和在樹林里走上兩小時所消耗的能量相同。確定水深要及胸(這是為了從水的阻力中獲得對身體的好處)然后就開始水中散步吧。
