Study Notes

Isotonic

Involves muscle contraction that leads to movement, enhancing muscular strength and flexibility.
Common exercises include squats, lunges, push-ups, jumping jacks, skiers, burpees, crunches, and running.

Isometric

Consists of tightening or contracting muscles without movement to build strength.
Examples include planks and wall sits.

Isokinetic

Involves moving weights or resistance through a full range of motion, promoting flexibility, strength, and endurance.
Common activities are bicep curls, medicine balls, ergs, kettlebells, and goblet squats.

Cardiovascular/Cardiorespiratory Endurance

Measures the heart's efficiency in pumping oxygen-rich blood and recovery post-activity.
Exercises include pacer tests, mile runs, and 10-minute runs.

Flexibility

Refers to the capacity of joints and surrounding muscles and tendons to move freely through their full range of motion.
An example is the sit and reach test.

Muscular Strength

Indicates a muscle or group's ability to exert maximum force against resistance.
Broad jumps are an example of a strength-focused exercise.

Muscular Endurance

The ability of a muscle group to sustain force over time against submaximal resistance.
Activities like minute pushups and minute sit-ups measure endurance.

Body Composition

Expresses the ratio of lean body mass (bone, muscle, organs) to body fat, typically as a percentage.
Often assessed through various body measurements.

Speed

Refers to the rate of motion or performance, emphasizing quickness.
An example is completing a 20-yard sprint.

Agility

The capacity to move quickly and easily, crucial in many physical activities.
Exercises like shuttle runs and dot drills enhance agility.

Power

Represents the ability to exert maximum effort or force quickly.
Broad jumps serve as a practical example of testing power.

Balance

The ability to maintain equilibrium, important for coordination and stability.
One-foot balancing exercises illustrate this skill.

Aerobic

Involves exercises that rely on continuous oxygen uptake over extended periods.
Activities such as run-walk routines exemplify aerobic exercise.

Anaerobic

Describes high-intensity exercises where oxygen demand exceeds supply.
Includes activities like sprints and short-distance rowing.

Warm-up

Aims to prepare the body by elevating heart rate, enhancing blood flow, increasing muscle flexibility, and improving muscle temperature, all reducing injury risk.

Main Physical Activity

Refers to specific exercises targeted to improve various health-related fitness components.

Cool Down

Involves activities that help the body return to a normal state, reducing muscle soreness and stress on bodily systems.

Overload

A principle of fitness involving increased resistance or stress (weight, time, repetitions) to enhance health-related fitness components.

Progression

Involves gradually increasing frequency, intensity, or duration in exercise routines to improve fitness levels over time.
