Training the Weak Muscle Right.

Name: S.P. Age: 26 Profession: Professional Sprinter (100m)

Injury: 2 severe hamstring strains (LHBF)

She has suffered 2 severe hamstring strains (LHBF) on her left leg. First one took palce during a competition and the second one was during the rehabilitation. She started with traditional heavy strength training including Olympic Lifting. Standard for the sport the athlete was aiming to go back to. 

KineMotion showed us that despite using the right exercises to target the injured muscle (hamstring), the athlete was compensating & most of the muscle signal was produced from the medial portion of the hamstring muscle. In other words, while the hamstring showed it was getting stronger weekly, the injured muscle wasn't since its signal under contraction was very poor. We used the biofeedback tool to help shift the brain pathway/activation she had adopted at the early stages of the rehab. We spent around 3weeks working on balancing the muscle signal between the medial and lateral hamstring with the biofeedback and afterwards, we continue working on strength as she had done previously. What we also noticed was that her strength markers went up way faster when the whole hamstring muscle worked in a balanced & conjunct way. 

She is now fully training again and working towards the indoor season starting around Spring time.
