SUMMARY
Introduction. Heavy Slow Resistance Training (HSR) is one of the most recommended interventions for the treatment of patellar tendinopathy (PT). However, the HSR protocol does not address known risk factors for PT. Athletes with PT have been shown to have stiff jump-landings, decreased ankle dorsiflexion range of motion and hip extensors strength compared to asymptomatic athletes. This study aims to verify the effects of an intervention addressing kinetic chain factors in comparison to the HSR protocol on pain, symptoms severity and function, strength and flexibility of the lower limb and landing mechanics in athletes with PT.
Methods. Blind randomized, clinical trial consisting of 28 male recreational athletes, divided into two groups: Heavy slow resistance training group (HSG; n = 14) and kinetic chain group (KCG; n = 14). Both interventions will be delivered 3 times per week, for 12 weeks. Pain will be measured with a visual analog scale and disability will be measured with the VISA-P questionnaire, at baseline, after 6 weeks of intervention, immediately after the intervention, as well as at 6 months after the interventions.
Lower limb strength and flexibility and landing mechanics will also be assessed before and after the 12-week interventions. The HSG intervention will involve the squat, Leg Press and Hack Squat, with progressive loads. The KCG intervention will involve the squat exercise, hip extensors and ankle plantar flexors strengthening, interventions to improve ankle dorsiflexion and a jump-landing training. General linear models will be
used to compare the intervention effects.
Results. The results of this study will expand the evidence base on different exercise programs for patellar tendinopathy, and may aid clinicians in choosing the most appropriate program for the treatment of athletes with this condition.
Conclusions. This randomized controlled trial will compare the effectiveness of an intervention addressing kinetic chain factors to a standard patellar tendon progressive loading program for the rehabilitation of athletes with patellar tendinopathy.
