Kinetic Energy
The energy of a body that it possesses due to its motion. A gymnast must efficiently convert kinetic energy to perform dynamic movements like somersaults and vaults.
Motor Control
The systematic regulation of muscle movement and the mechanisms that facilitate it. Motor control is key in gymnastics for executing complex movements with precision and grace.
Balance
The ability to maintain the body's center of mass over its base of support. A fundamental principle in gymnastics for holds, beam routines, and landings.
Moment of Inertia
A property of a body that determines the torque needed for a desired angular acceleration about an axis of rotation. The distribution of mass around the axis affects the performance of gymnasts, especially in rotations and twists.
Elastic Energy
The potential mechanical energy stored when a material is deformed. Gymnastic apparatus like the spring floor store elastic energy during athlete's movements, which then helps to power jumps and tumbling passes.
Torque
A measure of the force that can cause an object to rotate about an axis. For a gymnast, torque is important in initiating rotation around the apparatus or their own body axis.
Potential Energy
The stored energy of position possessed by a body. In gymnastics, potential energy is highest at the top of a vault or the peak of a jump, ready to be converted into kinetic energy.
Mechanical Advantage
The ratio of the force output to the force input within a system. A mechanic principle that gymnasts can use to their advantage when interacting with apparatus, leveraging gravity and momentum.
Projective Motion
The motion of an object thrown or projected into the air, subject to only the acceleration of gravity. Understanding the principles of projective motion allows gymnasts to optimize their vaults and jumps for maximum height and distance.
Flexibility
The capacity of the muscles and joints to stretch through an intended range of motion. Gymnasts require high levels of flexibility for movements like splits, bends, and twists.
Force
An influence that when applied to a mass imparts an acceleration. In gymnastics, understanding force is crucial for jumps and landings to generate powerful movements and to prevent injuries.
Impulse
The change in momentum of a body when a force is applied over time. Gymnasts use impulse to their advantage by applying a greater force over a longer period during takeoff to maximize their jumps.
Center of Mass
The point at which the distribution of the body's mass is equal in all directions and is the point at which all the mass can be considered as concentrated. In gymnastics, understanding the center of mass helps in stabilizing various poses and in executing flips and spins with better control.
Neuromuscular Coordination
The ability of the central nervous system to control the muscles in the execution of multi-limb functional movements. It's essential for gymnasts as they perform complex maneuvers that require precise timing and muscle control.
Biomechanics
The scientific study of the mechanics of movement of a living body. In gymnastics, biomechanical analysis can improve technique, enhance performance, and reduce injury risk.
Proprioception
The sense of self-movement and body position, sometimes described as the 'sixth sense'. It's crucial for gymnasts to perform precise and well-coordinated movements without watching every limb.
Levers
Rigid structures (like bones) that are used with a fulcrum (joint) to multiply the mechanical force. In gymnastics, arms and legs act as levers to perform movements with efficiency.
Angular Momentum
A measure of the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity. It remains constant when the body is in free rotation, which is crucial in skills like twists and somersaults in gymnastics.
Reaction Force
The force exerted by a body when it is in contact with another, according to Newton’s third law of motion. Gymnasts experience reaction forces during landings, handsprings, and when pushing off the ground or apparatus.
Power
The rate at which work is done or energy is transmitted. For gymnasts, generating power is crucial for explosive moves like vaults and tumbling passes.
