The FITT principle is a guideline used in exercise and physical activity to help individuals create effective workout plans. It stands for Frequency, Intensity, Time, and Type. Frequency refers to how often a person exercises, intensity refers to the level of difficulty or effort exerted during the exercise, time refers to the duration of the exercise session, and type refers to the specific activities or exercises chosen. By considering these four factors, individuals can tailor their workouts to meet their specific goals and needs.

The intensity of exercise refers to how hard we exercise. It is a measure of the level of exertion or effort put into the physical activity. Intensity can be determined by factors such as heart rate, breathing rate, and perceived exertion. Higher intensity exercise typically involves a higher heart rate and greater effort, while lower intensity exercise is less demanding. The intensity of exercise plays a significant role in determining the effectiveness and benefits of the workout, such as calorie burn and cardiovascular fitness.

Frequency refers to the rate or number of times an event or action occurs within a given time period. In this context, the correct answer is "How often we exercise," as it aligns with the definition of frequency. It refers to the regularity or number of times someone engages in physical activity or workouts. The other options, such as how often we don't exercise or how often we run, do not accurately define frequency in the context of the question.

An example of the standing long jump is power. Power is the ability to exert a maximum amount of force in a short amount of time. In the standing long jump, an individual needs to generate a significant amount of power in their legs to propel themselves forward and achieve a long jump distance. This requires explosive strength and the ability to generate force quickly.

The statement is true because cardiac output is the amount of blood pumped by the heart in one minute. It is calculated by multiplying the stroke volume (the amount of blood pumped with each heartbeat) by the heart rate (the number of times the heart beats per minute). Therefore, the formula Cardiac Output = Stroke Volume x Heart Rate is correct.

The correct answer is the ability of the body's circulatory and respiratory system to supply fuel and oxygen during exercise. This definition refers to the capacity of these systems to deliver the necessary nutrients and oxygen to the muscles and organs during physical activity. It highlights the importance of a strong cardiovascular system and efficient breathing in sustaining exercise performance.

Heart rate is the number of times the heart beats per minute. This is a measure of the frequency of the heart's contractions and is commonly used to assess cardiovascular health and fitness. Ventilation rate refers to the amount of air breathed into the lungs, cardiac output is the amount of blood pumped by the heart per minute, and stroke volume is the amount of blood pumped by the heart with each contraction.

The health-related components of physical fitness include the Cardiorespiratory System, Muscular Strength, Muscular Endurance, Flexibility, and Body Composition. These components are essential for maintaining overall health and well-being. The Cardiorespiratory System refers to the ability of the heart and lungs to supply oxygen to the muscles during physical activity. Muscular Strength is the ability of muscles to exert force against resistance, while Muscular Endurance is the ability to perform repetitive muscle contractions over an extended period. Flexibility refers to the range of motion in joints, and Body Composition refers to the proportion of fat, muscle, and other tissues in the body.

During exercise, the heart rate increases to meet the increased demand for oxygen and nutrients by the muscles. The correct answer of 60-85% indicates the target heart rate range that is recommended for most individuals during exercise. This range ensures that the heart is working at an optimal level, allowing for improved cardiovascular fitness and endurance. Going below this range may not provide enough stimulus for the heart, while going above it may be too strenuous and potentially harmful. Therefore, maintaining a heart rate within the 60-85% range is ideal for maximizing the benefits of exercise.
