The TYR Tracer Aeroback swimsuit compresses large muscle groups aids in the reduction of muscle fatigue and strain. The consistent, even firmness supports muscles efficiently without reducing movement so no energy in motion is wasted. The compression suit acts as a second, firmer skin, molding to the contours of the body, and improving blood circulation. The subtle rise in muscle temperature allows the body to meet its optimal performance level and maintain it the entire race. Reducing undulation increases efficient oxygen transfer throughout the circulatory system. A rise in oxygenation will keep muscles from fatiguing quickly and promotes muscle flexion and extension. The end result is faster swimming with lower energy depletion.
