Have you noticed that cyclists lean forward during a race? They do this to move through the air more easily. Air pushes against fast-moving objects, creating a force called drag. Sitting upright gives the wind a larger surface to push against. By lowering their heads and backs, cyclists make their bodies smaller and smoother, so they waste less energy fighting the air. This helps them ride faster without having to pedal much harder. Special helmets, tight clothing, and curved handlebars also help reduce drag.

Why Do Cyclists Bend Forward When Racing?
자전거 선수들이 경주하는 동안 몸을 앞으로 숙이는 것을 본 적이 있습니까?
그들은 공기 속을 더 쉽게 이동하기 위해 이렇게 합니다.
공기는 빠르게 움직이는 물체를 밀어, 항력이라고 불리는 힘을 만듭니다.
똑바로 앉는 것은 바람이 밀 수 있는 더 넓은 표면을 제공합니다.
머리와 등을 낮춤으로써, 자전거 선수들은 그들의 몸을 더 작고 매끄럽게 만들어 공기와 싸우는
데 더 적은 에너지를 낭비합니다.
이것은 그들이 페달을 훨씬 더 세게 밟지 않고도 더 빠르게 달리도록 도와줍니다.
특수 헬멧, 몸에 꼭 맞는 옷, 그리고 굽은 핸들바도 항력을 줄이는 데 도움을 줍니다.
