Episode notes
Fascicle Length & Hamstring Injury
- Increasing hamstring muscle fascicle length can significantly reduce hamstring strain injury risk.
- Each 0.5cm increase in biceps femoris long head fascicle length reduces the risk by nearly 74%, according to Timmins et al.
Static Stretching Limitations
- Static stretching provides only short-term flexibility gains, lasting about 20-30 minutes.
- It can also decrease strength and power immediately after stretching, impacting performance in activities like running.
Eccentric Loading for Flexibility
- Use eccentric loading exercises to build muscle strength and length simultaneously.
- This approach, unlike static stretching, may create lasting flexibility improvements by increasing fascicle length.
