Eccentric contraction, also known as lengthening contraction, occurs when a muscle lengthens while under tension. This type of muscle contraction is essential in sports as it allows athletes to control movements, slow down, and change direction. In this article, we will take a closer look at eccentric contraction examples in sport.
Running
Running is one of the best examples of eccentric contraction in sports. As the foot lands on the ground, the muscles in the leg have to control the speed and force of the body`s weight while lengthening. The quadriceps muscles, for instance, lengthen while controlling the descent of the body weight as the foot hits the ground.
Sprinting
Sprinting is another sport that requires eccentric contraction. In sprinting, eccentric contraction occurs when the foot lands on the ground and the leg muscles have to control the force of the body weight while slowing it down. Sprinters also use eccentric contraction to change direction during the race.
Jumping
Jumping is another sport that requires eccentric contraction. When an athlete jumps, the leg muscles lengthen while controlling the landing. The hamstrings muscles, for example, play a significant role in eccentric contraction during jumping, allowing the athlete to land safely.
Weightlifting
Weightlifting is another sport that requires eccentric contraction. In weightlifting, eccentric contraction occurs during the lowering phase of a lift. For instance, as a weightlifter lowers the barbell during a squat, the quadriceps muscles have to lengthen while controlling the descent of the weight.
Basketball
Basketball is a sport that requires eccentric contraction, especially during jumping and changing direction. When a basketball player jumps, the leg muscles lengthen while controlling the landing. Also, during a quick change of direction, eccentric contraction occurs as the athlete decelerates their body weight.
Conclusion
In conclusion, eccentric contraction is an essential aspect of sports. Athletes in various sports use eccentric contraction to control their movements, slow down, and change direction. Understanding and training eccentric contraction can improve an athlete`s performance, reduce the risk of injury, and enhance overall fitness.
