ClinConnect Summary

This clinical trial is looking at how the time of day affects the training of people with a condition called chronic patellar tendinopathy, often known as jumper's knee. Over 12 weeks, 60 active participants aged 18 to 55 will be split into two groups: one group will do strength exercises in the morning, while the other group will train in the late afternoon. The goal is to find out if training at different times helps improve their knee condition more effectively. Additionally, 10 healthy individuals will be included as a comparison group and will not participate in any exercise training.

To be eligible for this study, participants should be physically active, have been experiencing knee pain for more than three months, and meet certain health criteria, such as a body mass index (BMI) between 18.5 and 30. Those with more serious knee issues, recent surgeries, or other health conditions like diabetes or arthritis cannot participate. Participants can expect to engage in a structured exercise program and will be monitored throughout the study to track their progress. This research could help find the best way to support people dealing with knee pain through targeted exercise.
