人类身体存在生理极限 据英国《新科学家》杂志我们拥有向人类极限挑战并创造纪录的无法抑制的渴望。然而,我们在心理和生理上距离最终极限又有多远呢­­  人类的速度极限是多少  牙买加飞人博尔特在2009年柏林世锦赛打破世界百米纪录摘金,又将由他自己保持的世界纪录提高了0.11秒。人类的速度极限究竟是多少­美国斯坦福大学的马克-丹尼(MarkDenny)对这个问题十分好奇,决定对人类百米速度究竟有多快进行深入探究。  他通过分析1920年以来各种田径比赛(甚至包括赛马之类的比赛)的世界记录,发现许多比赛的成绩都遵循类似的模式,即成绩逐步提高直至稳定。例如肯塔基赛马会,许多参赛马匹在1949年达到速度极限之后就很难再有突破。人类运动员看上去一样遵循这个模式。女子百米成绩在1977年趋于稳定,男子短跑成绩仍然在提高,不过丹尼表示,基于其它赛事所建立的模型,这一成绩看上去也快到达极限。  根据他的预测,男子百米成绩的极限是9.48秒,只比博尔特当前世界记录少0.1秒。丹尼说:“如果继续保持现在这种势头,博尔特不久便会接近于这个极限。”是什么原因产生的这个人类速度极限­丹尼认为,原因类似于运动员的力量-重量比。超过某个点,更强健肌肉和更长四肢的优势将会被举起更重重物所增加的能量消耗所抵消。
