Adaptation

something produced to adjust to different conditions or uses, or to meet different situations

Aerobic exercise

involves continuous, rhythmic activities that elevate your heart rate and breathing, using oxygen to produce energy

Anaerobic exercise

short, intense activity that uses stored energy within muscles, rather than relying on oxygen for energy

Cardiovascular endurance

the ability of your heart and lungs to efficiently deliver oxygen to your muscles during sustained physical activity

Concentric exercise

a type of muscle contraction where the muscle shortens as it contracts against resistance

Cool down

the process of easing your body back to a resting state after physical activity

Diminishing return

as one input in a production process is increased while all other inputs are held constant, the marginal output (the additional output from that input) will eventually decline

Eccentric exercise

involve muscle contractions where the muscle lengthens while resisting force, commonly known as "negatives"

Exercise plateau

occurs when your body stops making progress, even with continued effort, due to adaptation to your current workout routine.

F.I.T.T. principle

a framework for designing exercise programs, standing for Frequency, Intensity, Time, and Type

Flexibility

the quality of bending easily without breaking.

heart rate

between 60 and 100 beats per minute

Muscular contraction

the process by which muscles shorten and generate force.

Muscular endurance

the ability of a muscle or group of muscles to sustain repeated contractions over a prolonged period without fatigue

Muscular strength

the ability of a muscle to exert force against a resistance

Overload principle

the body will adapt and improve in response to progressively increasing demands placed upon it.

Plyometrics

exercises that involve rapid stretching and contracting of muscles, typically through jumping or explosive movements, to improve muscle power and speed

Range of motion

the extent of movement a joint can achieve in all directions

Repetitions

the action of repeating something that has already been said or written.

Warm-up

prepare for physical exertion or a performance by exercising or practicing gently beforehand.
