健康的跑步也有讲究

    With their special padding and hightech soles, you’d think that running shoes were designed to keep your feet healthy.
    你可能认为跑步鞋拥有特殊衬垫和高科技鞋底的设计会保持你的双脚健康。
    But, in fact, a recent study shows running without shoes is actually healthier. That’s because when you run with shoes on, you tend to land on your heels. Barefoot runners land on the balls of their feet. Striking the ground with the smaller area near the front of the foot is less forceful and does less damage than landing square on your heel.
    但事实上，最近的一项研究显示，光脚跑步实际更健康。那是因为当你穿鞋跑步时，往往是鞋跟着地。而光脚跑步者是前脚掌着地。用靠近脚掌前端的较小区域触地比脚跟着地压力要小，损伤也要少。
    But don’t chuck your running shoes just yet. For anyone interest in giving their foot running a try, fitness experts advise easing into it, allowing enough time to build strength in your calves¹ and feet.
    不过不要马上就扔掉跑步鞋，健身专家建议想要尝试光脚跑步的人要循序渐进，以获得充足的时间来增强小腿和双脚的力量。
