About

The aim of this study are to analyze the effect of creatine ingestion in pain, histological properties of the tendon, body composition, strength and vertical jump performance in athletes with patellar tendinopathy that follow a physical rehabilitation program that include eccentric exercise combined with stretching and extracorporeal shock wave therapy.

Full description

Nutrition could play an important role in the rehabilitation from sport injuries. This afirmation is based on studies that analyze the impact of different dietary supplements along immobilization periods, stablishing that creatine, leucine and omega-3 fatty acid supplementation could ameliorate muscle loss, while creatine could potentiate the hypertrophy along the rehabilitation process. For this reason, the aim of this study are to analyze the effect of creatine ingestion in pain, histological properties of the tendon, body composition, strength and vertical jump performance in athletes with patellar tendinopathy that follow a physical rehabilitation program that include eccentric exercise combined with stretching and extracorporeal shock wave therapy.
