Physical Fitness Definitions and Components

A set of flashcards covering key concepts related to physical fitness, exercise types, and training principles.

Physical Activity

Any movement.

Exercise

Planned, structured activity.

Physical Fitness

Ability to perform daily tasks.

Cardiorespiratory Endurance

Health-related component related to the efficiency of the cardiovascular and respiratory systems.

Muscular Strength

Maximum amount of force exerted by a muscle.

Muscular Endurance

Ability of a muscle to sustain repeated contractions.

Flexibility

Range of motion around a joint.

Body Composition

The proportion of fat mass vs lean mass in the body.

BMI

Height/weight ratio that does not distinguish between muscle and fat.

Active Range of Motion (ROM)

Self-movement.

Passive Range of Motion (ROM)

Assisted movement.

Static Stretching

Holding a stretch for a period of time.

Dynamic Stretching

Movement-based stretching.

PNF Stretching

Proprioceptive Neuromuscular Facilitation; involves contracting and relaxing muscles.

Agility

Ability to move quickly and change direction.

Balance

Ability to maintain stability.

Coordination

Ability to use different parts of the body together smoothly.

Power

The ability to exert force rapidly.

Reaction Time

The time taken to respond to a stimulus.

Speed

Ability to move quickly over a distance.

Overload

Stressing the body above normal.

Progression

Gradual increase in training intensity.

Specificity

Training in a way that specifically improves the desired skill or component.

Reversibility

The principle that fitness gains can be lost if training stops.

Warm-Up

A preparatory activity that reduces injury risk and enhances performance.

Cool-Down

Post-exercise activity to prevent blood pooling and promote gradual heart rate reduction.
