Final answer:
In freestyle swimming, a streamlined body position can minimize drag and turbulence, which are the resistive forces impeding a swimmer's movement through water. Swimmers and cyclists wear body suits to decrease these forces and improve performance, but they must also consider potential downsides such as restricted movement and overheating.
Step-by-step explanation:
In freestyle swimming, establishing an overall streamlined body position can minimize the forces of resistance known as drag and turbulence. Drag is the resistance caused by the swimmer's body moving through the water, while turbulence refers to the swirls and eddies generated as water flows around the swimmer's body. By maintaining a streamlined position, swimmers can reduce the impact of these forces, leading to more efficient and faster swimming.
Athletes, including swimmers and bicyclists, wear body suits to reduce these resistive forces. The suits are designed to be smooth and tight-fitting, reducing the unevenness of the skin and other irregularities that could increase drag and disrupt flow lines around the body, hence, improving performance in the water or on the bicycle. However, there may be cons such as limited mobility depending on the fit and fabric, potential overheating because of the coverage, and the rules implemented by governing bodies of sports which could limit the use of certain types of body suits.
