Two Biomechanics Frameworks To Think In
- Matt Casturo introduces two frameworks: orientation and joint actions to deepen biomechanics understanding.
- These frameworks help coaches move beyond muscle lists to joint-level movement and coaching strategies.
Posture Changes Shift Baseline Muscle Strain
- Anterior pelvic tilt lengthens the hamstring and shifts baseline strain on the muscle.
- Small posture changes (e.g., 5° tilt → ~1 cm length) alter hamstring load at rest and during sport.
Pregnancy Example Of Postural Strain
- Matt mentions his pregnant wife as an example of increased anterior pelvic tilt affecting hip stress.
- He uses this personal example to illustrate how daily life shifts length-tension relationships.
