Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to examine the regional protein turnover in tendon tissue from patients with chronic patellar tendinopathy and comparing this to healthy controls. Further we will examine the effect of resistance training on protein turnover in healthy individuals.
