Study Notes
Human Movement Science
- Pronation of the foot involves multiplanar movements including eversion, dorsiflexion, and ankle abduction.
- Stretch-shortening cycle efficiently stores energy released during concentric muscle actions.
- Upper trapezius acts in collaboration with the serratus anterior to achieve upward rotation of the scapula.
- Torque is affected by the length of the lever arm and the angle between the applied force and lever arm.
- During a squat, hip abductors engage isometrically to stabilize the thigh and limit unnecessary lateral movement.
- Shoulder horizontal adduction and abduction take place in the transverse plane of movement.
- The erector spinae is classified as part of the global muscular system, contributing to overall stability and function.
- Performance in plyometric jumps is enhanced by a rapid amortization phase, which minimizes ground contact time.
- Isokinetic exercises provide variable resistance that increases with the effort exerted, while maintaining a constant speed.
- A first class lever features the fulcrum positioned centrally, similar to a seesaw, balancing forces on either side.
