RELACIÓN DE LA FUERZA EN CUÁDRICEPS , LA FUNCIÓN Y LA SINTOMAS DE LA RODILLA ENTENDINOPATÍA ROTULIANA EN PERSONAS QUE ENTRENAN FUERZA

The purpose of this research was to analyze the relationship between quadriceps strength, function, and symptomatology of patellar tendinopathy in individuals who train in a gym setting. A quantitative, observational, prospective, and cross-sectional study was conducted with a sample of 92 participants (aged 18 to 35), all of whom had at least six months of strength training experience. Anthropometric variables were assessed, quadriceps strength was measured using a portable dynamometer (Kinvent), and function/pain was evaluated through the VISA-P questionnaire. The results showed that quadriceps strength had a very weak correlation with pain associated with patellar tendinopathy (r = 0.0878 in participants with tendinopathy and r = -0.0026 in those without tendinopathy). These findings indicate that although muscle strength is important for knee stability, it is not a primary predictor of pain in this condition. In conclusion, patellar tendinopathy is a multifactorial phenomenon influenced not only by muscle strength but also by biomechanical, functional, and load-related factors. Therefore, quadriceps strengthening alone may not be sufficient for symptom reduction, highlighting the need for a comprehensive approach to prevention, treatment, and rehabilitation.
