Sports Safety and Exercise Principles Quiz

A gradual increase in heart rate and body temperature, preparing the body for physical activity.

A series of exercises that increase flexibility and mobility in the body's joints.

A gradual decrease in heart rate and body temperature, allowing the body to recover from physical activity.

Wearing proper clothing and footwear to protect yourself during physical activity.

A series of exercises that help to improve flexibility and range of motion.

The floor should be in good condition, free from slippery areas. Also, no objects should be left lying around that could cause someone to slip.

Any equipment that's not being used should be stored away properly to prevent accidents.

Benches, curtains, or any obstacles that could cause someone to trip should be kept out of the way.

Before using any equipment in a fitness center, make sure you've been trained on how to use it safely. Also, it's essential to work out under the supervision of a qualified instructor.

The playing field should be free of hazards, like holes, mounds, and loose objects. The grass should be kept short, and the area should be free of litter.

The immovable point around which a lever rotates.

The force applied to move a lever. Usually muscles.

The weight or resistance that the lever moves.

Fulcrum is in the middle, between the load and effort. Example: Head moving up and down.

Load is in the middle, between the fulcrum and effort. Example: Standing on your toes.

Effort is in the middle, between the fulcrum and load. Example: Lifting an object with your elbow.

Blood leaving the lungs and traveling to the rest of the body.

Blood returning to the lungs to pick up oxygen.

Ability to repeatedly perform muscular movements without getting fatigued.

The ability to change direction quickly and at speed.

The ability of muscles to exert force.

Ability to stay upright or in control of body movement.

The ability to continue physical exertion while getting energy from the aerobic system.

Connects bone to bone, providing stability and limiting excessive joint movement.

Reduces friction and acts as a shock absorber, allowing smooth joint movement.

Connects muscle to bone, transmitting force to move bones.

The muscle that contracts and shortens, creating movement.

A set of muscles that work together, with one contracting (agonist) and the other relaxing (antagonist) to control movement.

The amount of blood that the heart pumps out of the left ventricle with each beat.

The number of times the heart beats in one minute.

The amount of blood that the heart pumps out of the left ventricle every minute.

Red blood cells transport oxygen from the lungs to the muscles and carry carbon dioxide from the muscles to the lungs.

Tiny air sacs at the end of bronchioles where gas exchange (oxygen and carbon dioxide) takes place.

The process of breathing in, where air enters the lungs.

The process of breathing out, where air leaves the lungs.

A sheet of muscle below the lungs that contracts and relaxes to help with breathing.

The framework of the body, providing support, protection, and enabling movement. It's composed of bones held together by ligaments and serves as an attachment point for muscles.

Connective tissue that provides support, protection, and helps with movement. They are held together by ligaments, forming the skeletal system.

A joint that allows movement in one direction, like a door hinge. Examples include the knee and elbow.

A joint that allows for a wide range of movement, like a ball in a socket. Examples include the shoulder and hip.

The process of straightening a limb at a joint. It's the opposite of bending or flexing.

Training should match the specific needs of the sport or individual.

The body adapts to increased physical demands.

Stress applied to the body must be greater than normal to induce adaptations.

Training adaptations are lost if the individual stops training.

Alternating between high-intensity periods and recovery.

The amount of air inhaled or exhaled with each normal breath.

The rate at which a person breathes, measured in breaths per minute.

The amount of air inhaled or exhaled in one minute. Calculated by multiplying tidal volume and breathing rate.

Exercise performed with oxygen, allowing for long duration and lower intensity. Uses glucose for fuel and produces energy, water, and carbon dioxide.

Exercise performed without sufficient oxygen, promoting short bursts of high intensity. Uses glucose for fuel and produces energy and lactic acid.
