Study Notes
- Kinesiology is the study of human movement.
- Biomechanics (human kinetics) involves studying movement mechanics, including forces like gravity and friction acting on the body.
- Quantitative biomechanical analysis uses accurate measurements and data analysis of human movements.
- Qualitative biomechanical analysis involves observational analysis.
- Motor Learning refers to acquiring and refining movement skills.
- Proprioception is the body's ability to sense movement and position.
- Agility is the ability to change direction quickly.
- Balance is the ability to maintain stability.
- Coordination is the ability to use different body parts smoothly and efficiently.
- Force is a push or pull that changes an object's motion.
- Torque is a force that causes rotation.
- Mechanical execution is defined as movement execution
- Physiological aspects relate to muscle function, energy use, and recovery.
- Velocity is speed in a given direction.
- Acceleration is the rate of change of velocity.
- The Center of Gravity is the point at which the body's mass is evenly distributed.
- Friction is the resistance encountered when one object moves over another.
- Leverage involves using a lever to increase force or motion.
- Kinematic describes motion.
- Linear motion involves movement in a straight or curved path, such as a sprinter running.
- Angular motion involves movement around an axis, like a gymnast swinging around a bar.
- General motion is a combination of linear and angular motion, like a car driving straight with rotating wheels.
- Vector is a quantity that has both size (magnitude) and direction.
- Horizontal force affects speed and distance, such as a sprinter's forward motion.
- Vertical Force affects height & jump, such as a high jumper’s takeoff.
- Resultant force combines vectors, like an angled force in kicking a soccer ball.
- The Force-Velocity relationship determines performance in strength and power activities.
- Kinetics involves forces causing motion.
- Newton's Law of inertia states that an object remains at rest or in motion unless acted on by an external force.
- Newton's law of acceleration: Force = Mass x Acceleration; the same force results in different accelerations due to mass differences, like throwing a shot put versus a baseball.
- Newton's law of action-reaction states that every action has an equal and opposite reaction, such as a sprinter pushing against the track.
- Sequential Summation involves small muscles initiating motion, and larger muscles adding force, like throwing a baseball.
- Simultaneous summation involves multiple muscles generating force at the same time, like a snatch lift.
- Static equilibrium is a state of no motion where all forces are balanced, like a gymnast holding a handstand.
- Dynamic equilibrium involves maintaining motion while resisting external forces, like cycling balance.
