- Registration Number
- NCT06482619
- Lead Sponsor

- Brief Summary
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.
- Detailed 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.

- Primary Outcome Measures
Name Time Method Pain evaluation 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. 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.
- Secondary Outcome Measures
Name Time Method Neuromuscular function 8-weeks Participants performed a neuromuscular test battery consisted in measuring vertical jump capacity (i.e., countermovement jump) and knee extension muscle strength muscular strength in a knee extension machine (Selection Leg Extension, Technogym, Cesena, Italy) with a 5 maximum number of repetitions (5-RM)
