【台灣醒報記者莊瑞萌報導】田徑場上非洲裔黑人通常是佼佼者,但在泳賽則通常為白人
的天下,現在科學家已經找出答案:問題就在這些選手的肚臍決定了上下半身的比例,讓
這2項運動所需的衝刺力道與製造波浪能力,明顯佔到優勢。
根據美國杜克大學研究人員指出,肚臍是身體的重心,非洲裔選手身材上肚臍位置明顯比
白人還高,因此身體重心較高腿部較長,比較能幫助選手在短跑或田徑場上進行速度衝刺
,而泳池上需要製造波浪以利身體往前進,這點在軀幹較長的白人上較佔優勢,大約增加
1.5%的速度優勢,另外亞洲人在體型上也同樣與白人有這點優勢,因此泳池表現也有潛
力。
根據研究人員博江指出,「非洲裔選手移動時身體上半身不斷向前傾可以製造更多的力量
,」而在游池裡,白人的優勢在肚臍較低因此軀幹較長。
過去學者通常會避免研究黑白人在運動場上的優勢,以免引起「種族」議題看法而模糊焦
點,不過身為白人的他與另一名黑人的研究人員,從過去近100年來,男子與女子短跑與
自由式成績紀錄來分析,因此得到這些結果。
這次研究結果同時登在《The International Journal of Design & Nature
and Ecodynamics 》期刊上。
