An interventional study of Heavy slow resistance training and Moderate slow resistance training in Patellar Tendinopathy and Jumper's Knee, sponsored by Bispebjerg Hospital. Completed at 1 site in Denmark. Open to male participants aged 20 Years to 45 Years. Per ClinicalTrials.gov, last updated 2022-03-08.
Sponsored by Bispebjerg Hospital · Not applicable, Interventional, and Treatment
The purpose of this project is to investigate if the magnitude of a loading based 12 weeks rehabilitation regime for patellar tendinopathy influence the clinical outcome, tendon structure and function.
The investigators hypothesize that a greater magnitude (90% of 1RM) of loading will yield a more positive clinical outcome, tendon structure and function in patients with patellar tendinopathy compared to a lower magnitude of loading (55% of 1 RM) when total exercise volume is equal in both groups.
