According to the principles of FITT, what is the relation between the intensity of an exercise and the time an exercise needs to be performed?
Higher-intensity exercise requires less time to achieve the same benefit, while lower-intensity exercise requires more time.
Why do exercise needs vary between individuals?
Individuals differ in age, current fitness level, health status, exercise goals, and genetic factors, so exercise programs must be personalized to be safe and effective.
Explain why exercise programs must increase in difficulty and duration over time to remain effective.
The body gradually adapts to a repeated workout, so the same exercise eventually produces less challenge and fewer gains. Increasing the program's difficulty or duration provides progressive overload, allowing fitness, strength, and endurance to continue improving safely.
Explain the tangible physical benefits of warming up for and cooling down from a workout activity.
Warming up gradually increases body temperature, heart rate, and blood flow while loosening muscles and joints and preparing the body for exercise. Cooling down gradually lowers heart rate and breathing, keeps blood circulating, and helps prevent dizziness and blood pooling after the workout.
Why should a good warm-up include stretching and activity-specific warm-up actions?
Stretching improves flexibility and range of motion; activity-specific movements activate the exact muscles and movement patterns used in the workout, enhancing performance and reducing injury risk.
