Question

6. If you are walking at a pace that causes your heart to beat less than 50% of its
maximum heart rate, which of the following FITT principle variable do you need to
change to improve your endurance?
A. Frequency
B.Type
C. time
D. intensity​

Answer 1

FITT principle variable to determine heart rate based on physical exercise

Explanation:

• If a person  walking at a pace that causes the heart to beat less than 50% of its  maximum heart rate, based on FITT principle variable intensity is changed  to the improve the endurance. So, option D is correct.

FITT principle

The FITT principle is a prescription for exercise that will assist participants in determining how long and how hard they should exercise. Abbreviation for FITT is Frequency, Intensity, Time, and Type.

Intensity

• Intensity is nothing but how hard the work is done. Intensity is one of the most important factors in determining whether a person is exercising at a level that is beneficial to the heart. This is known as  Target Heart Rate (THR) Zone.
• To calculate the target heart rate zone, charts have been developed.
• Determining whether a person's pulse or heart rate is within the target zone during physical activity is one method of monitoring physical activity intensity.
• If the heart rate is less than 50%, then the person is physically fit. For a 50-year-old to engage in moderate-intensity physical activity, the heart rate must remain between 85 and 119 beats per minute.
• For a 35-year-old to engage in vigorous-intensity physical activity, the heart rate must remain between 130 and 157 beats per minute.
• Based on the heart rate, the intensity of the physical activity can be varied to improve endurance.

Answer 2

Answer:

The correct option is  D

Explanation:

Based on the FITT principle, variable intensity is changed to the improve the endurance if a person walks at a pace that causes the heart to beat less than 50% of its maximal heart rate.

The FITT principles are a set of guidelines that individuals can use to determine how long and how hard they should exercise.

Frequency, Intensity, Time, and Type are all acronyms for Frequency, Intensity, Time, and Type. FITT can be used to describe overall activity or specific aspects of exercise. Here are some general FITT guidelines for weekly exercise, for example.

Frequency: Daily moderate activity is desirable, but a minimum of 3-5 days per week is recommended.

Intensity:  Adults should exercise at a moderate to high intensity.

Daily time: 30-60 minutes is recommended

Type:  Perform a range of workouts, including cardio, strength, and flexibility, to maintain a well-balanced fitness level.
