Hamstring flexibility is often discussed in relation to movement quality, pelvic control and balance. But does greater flexibility actually translate into better postural control? A recent cross-sectional observational study cross-sectional study investigated this question in 70 healthy young adults aged 18–30 years. Participants were assessed using the sit-and-reach test for hamstring flexibility, the Y Balance Test for postural control, the Biodex Overall Stability Index

Hamstring strain injuries most commonly affect the biceps femoris long head, particularly near the myotendinous junction. While strengthening exercises are a cornerstone of injury prevention, the role of the aponeurosis (the connective tissue within and around the muscle) has received much less attention. A recent MRI study compared 10 weeks of eccentric hamstring training (on a isokinetic dynamometer) with time-matched static stretching (maximal knee extension, for 3x ~68 se
