Most Common Reason to Pull Your Hamstring
The hamstring muscle is one of the most common fast running sports injury. Do you know that feeling when you’re sprinting for the end and next thing you feel that “ping or snapping feeling” in the back your thigh? That is probably a pulled hamstring muscle.
The way the hamstring muscle is normally injured is by what is termed an eccentric muscle contraction. If you don’t know what I mean by eccentric contraction don’t worry I explain it easily in the video below.
Most Common Hamstring Injury
The athlete pulling their hamstring in the video is American athlete, LoLo Jones. You can see Lolo pulling her right hamstring muscle during the hurdling race. She gives herself a sports injury while trying to control her right leg going over the hurdle. This is an eccentric muscle injury.
Eccentric muscle contraction means when your hamstring muscle is being stretched, but at the same time, contracting (tightening) to control that rate of stretch in the muscle.
When running the eccentric contraction is when your leg is swinging through to go in front of you and your foot hits the ground. Can you see it? Your hamstring muscle is stretching as your leg is swinging through, but the hamstring also has to tighten up to be able to control the speed of the swinging of your leg so you have balance.
There are four parts to the hamstring muscle. The short head of the biceps femoris muscle is the most commonly injured hamstring muscle.
So the next time a friend in your football or rugby team “pulls a hamme” the probably did an eccentric type muscle injury in the short head of the biceps femoris.
To come will be more about the different types of pulled hamstring and how to treat a pulled hamstring.
