What did I do?

First I looked to see if two-dimensional ultrasound could show us anything new in the battle against hamstring strain injuries (HSI), mainly in those with a history of injury, but also seeing if biceps femoris long head (BFlh) architecture alters future injury risk. I then implemented a resistance training programme to see if we can change these characteristics which increased the risk of HSI.

Why did I do it?

In a number of sports, HSIs are consistently the most common, non-contact injury with a high risk for recurrence.1 ,4 This suggests we still do not fully understand the aetiology of hamstring injury and re-injury. Non-modifiable risk factors (eg, increasing age and a previous injury history) have been shown to increase HSI risk; yet there are still a number of potentially modifiable risk factors that are …
