ClinConnect Summary

This clinical trial is investigating how different intensities of strength training can help men recover after an Achilles tendon rupture. The study focuses on understanding how strength training affects the properties of muscles and tendons in the lower leg, which can be impacted by this injury. Specifically, it will look at changes in muscle strength, function, and the physical characteristics of the Achilles tendon after participants complete a 12-week training program.

To participate, men aged 18 to 64 who have experienced a total rupture of their Achilles tendon within the last five years and are not currently engaged in regular strength training can apply. Participants will be divided into two groups, with one group doing low-intensity training and the other doing moderate-intensity training, both meeting twice a week. Throughout the trial, their progress will be monitored through various tests before and after the training period to see how well the strength training helps improve their condition. It's a chance to potentially enhance recovery and regain strength after a significant injury.
