Study Notes
Musculoskeletal Physiology - Biomechanics
- This course covers the biomechanics of the musculoskeletal system, focusing on how movements are measured and forces are generated.
- The course will include the study of introductory concepts, measuring movements (kinematics), and measuring force and speed (kinetics).
- Kinematics examines the types of movements around joints, angles, and lever systems.
- Kinetics investigates muscle force generation, ground reaction forces, and joint pressures.
- Biomechanics applies engineering principles to understand how the human body functions, particularly regarding joint movements.
- Biomechanics also considers the cardiovascular system, but primarily focuses on joint movements.
- Measurement of movement involves using goniometers to measure angles.
- Levers are a key concept, with three types (first, second, and third class) categorized by the positioning of the load, fulcrum, and force.
- Types of movements at joints include hinge, ball-and-socket, pivot, saddle, and mortise-tenon joints.
- Forces of movement, such as those related to body weight, can be measured in the laboratory.
- The force exerted on a joint is also affected by shape, where broad ends help reduce forces.
