Sat 11th Jan will be live on the AASPT Sports Performance ‘Casual Chats’ talking about my PhD work, hamstrings, likely some tendons, and probably some adjacent topics.

Link can be found on their Insta page but will try to post here nearer the time.

Neither the NHE or HE induced change in the proximal aponeurosis MTJ interface area. But since the HE exercise ⬆️ muscle volume, the muscle-to-aponeurosis ratio also ⬆️ vs the NHE or control groups.

In the third and most recent paper (2024), we reviewed Bourne et al.’s (2017) RCT using the #Nordic vs 45° Hip extension intervention.

Despite muscular hypertrophy, there was limited tendon geometric adaption over 10 wks.

In the second thesis paper (2024), we showed those w a history of unilateral #HSI had larger biceps fem long head aponeurosis volumes and smaller muscle-to-aponeurosis ratio versus healthy controls. There were no other noted diffs (see ❌).

We were also able to show through meta-regression that difference in stiffness was best explained by difference in modulus, and that high mechanical strain vs low strain interventions significantly increased modulus and stiffness.
