Hypothesis
Eccentric training would increase fascicle length in persons with Achilles tendon rupture who have been left with an elongated tendon and shortened GM fascicles.
Conclusion
Fascicle length was not altered by the intervention, but plantar flexion torque, heel-rise count, and the patient-reported outcome measure ATRS improved.
Supporting Evidence
- Participants showed significant improvements in heel-rise count and plantar flexion torque after 12 weeks of training.
- Despite no change in fascicle length, the ATRS score improved significantly.
- Participants reported better functional outcomes and reduced fat content in the triceps surae.
Takeaway
People with a torn Achilles tendon can get stronger and do better on certain tests after doing special exercises for 12 weeks, even if their muscle length doesn't change.
Methodology
Participants underwent a 12-week isokinetic eccentric training program, with measurements taken before and after the intervention.
Potential Biases
Participants were self-recruited via social media, which may introduce selection bias.
Limitations
The study had a small sample size and the training period may not have been long enough to see changes in fascicle length.
Participant Demographics
14 participants (12 men, 2 women), mean age 48 years.
