Comparing Early Plyometric Exercises Versus Traditional Heavy Slow Resistance Training for Rehabilitation of Achilles, Patellar, and Plantar Tendinopathies

What this Trial Is About

Researchers are evaluating whether an early plyometric exercise approach improves recovery compared to traditional heavy, slow resistance training in people with tendinopathies of the Achilles tendon, patellar tendon, or plantar fascia. These common conditions cause pain, reduced function, and stiffness, often leading to long recovery times and incomplete return to sports. The study aims to see if early plyometric exercises can improve jump function after 12 weeks and reduce re-injury rates after 52 weeks. The trial includes 120 participants aged 18 to 50 who regularly engage in running or jumping sports and have symptoms lasting at least three months. Participants are randomly assigned to two groups one performs heavy slow resistance training alone, while the other combines this training with a progressive plyometric exercise program. Both groups exercise three times weekly for 12 weeks, with plyometric training progressing through three levels based on self-assessed readiness. Participants will be assessed at the start, after 12 weeks, and at 52 weeks. Tests include measuring jump function using a force platform, dynamic strength, jump height, and pain thresholds. Questionnaires will capture symptoms, exercise compliance, return to sport, adverse events, re-injury rates, and psychological readiness. The main measure is the change in plyometric quotient over 12 weeks, showing functional ability improvements.
