" Everyone underestimates downhills, generally because they don't present much of a challenge to negotiate," says coach and exercise physiologist Jack Daniels, Ph.D.
“所有的人都低估了下坡跑,主要是因为它们暗藏杀机,”教练和运动生理学家,Jack Daniels博士说。
In addition to changing surfaces, a typical cross-country course may also involve twists and turns and short — but steep — uphills and downhills.
