Show Answers Only
Sample Answer
Descent:
- Hip, knee and ankle joints flex while quadriceps and gluteal muscles lengthen eccentrically to control downward movement.
- Skeletal system provides stable framework as muscles work to control lowering speed.
Bottom Position:
- Skeletal joints maintain alignment while muscles sustain isometric contraction to hold position.
- Bones bear body weight as muscles stabilise.
Rising:
- Quadriceps and gluteal muscles contract concentrically to extend joints.
- Skeleton provides mechanical leverage while muscles generate upward force through bone attachments.
