简要总结
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.
详细描述
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.

盲法说明
A researcher who did not have any contact with the participants and the physiotherapist who performed the physical rehabilitation intervention and the assessments randomly divided the participants to the creatine or placebo groups in a computerized random list with a 1:1 allocation using the software Research Randomizer (www.randomizer.org).

结局指标
主要结局
Pain evaluation
时间窗: 8-weeks
For assessing pain, the Victorian Institute for Sports Assessment - Patella (VISA - P), the most widely used patient-reported outcome measure (including symptom severity), was administered . The VISA - P will be scored with a maximum of 100 points and the higher scores indicate better function, and it shows sensible to identify improvements in therapeutic interventions among patients with tendinopathies.
Tendon thickness.
时间窗: 8-weeks
Thickness Tendon of the injuried knee/s was analyzed with ultrasound (GE VENUE 40, Portable Ultrasound, CA, USA), and a linear translator. Participants were positioned supine with a 30º knee flexion (using a roller under the knees), reducing the "locking" of the patella in the femur as in full extension. Ultrasound gel was applied and evaluated by placing the probe longitudinally; in pathological tendons it is the only way to determine the distance of the measurement point from the insertion of the tendon. Thus, subsequent measurements were always made from the same point.
