Reaction time, speed, and power are the most important skill-related fitness components that every sprinter must excel at during the race.
Strength is defined as the ability to generate force (lifting heavy weights) speed: the ability to move quickly (sprinting) Endurance is the ability to withstand fatigue (running a marathon) Flexibility is the ability to achieve a wide range of motion at the joints (doing a split) Power is defined as the ability to exert maximum muscular contraction in an explosive burst of movements. Strength and speed are the two components of power. (For example, jumping or a sprint start) Aerobic endurance is also known as cardiovascular endurance. Marathon runners and distance cyclists need a high level of aerobic endurance to be able to work for an extended period of time during a race.
