Exercise Prescription and MFIT Principle

Which component of the MFIT principle specifies how often exercise sessions should occur?

• Mode

• Frequency

• Intensity

• Time

In an exercise prescription, "intensity" is most directly measured by?

• Resting heart rate

• Rating of Perceived Exertion (RPE)

• Flexibility range

• Exercise duration

A client aims to improve cardiovascular endurance. According to MFIT, which prescription is most appropriate?

• Walking, 1x per week, low intensity, 10 minutes

• Jogging, 3x per week, moderate intensity, 30 minutes

• Weightlifting, 5x per week, maximal effort, 15 minutes

• Stretching, daily, low intensity, 5 minutes

An overweight beginner asks how to start exercising safely. Which adjustment in MFIT is most important at the start?

• Increase time immediately to 60 minutes

• Begin with high intensity for fat loss

• Start with low intensity and moderate frequency

• Eliminate mode selection to avoid fatigue

A patient with hypertension is advised to exercise. Which MFIT adjustment is most critical?

• High intensity, short time

• Moderate intensity, frequent sessions

• Low frequency, long duration

• Maximal intensity, 1x per week

A runner increases training days from 3 to 6 but keeps duration and intensity the same. Which MFIT component is primarily affected?

• Mode

• Frequency

• Intensity

• Time

A 45-year-old sedentary man plans to exercise daily at vigorous intensity for 90 minutes. Which is the most appropriate critique?

• The plan follows MFIT perfectly

• Frequency and time are excessive for his status

• Intensity is too low to improve fitness

• Mode is inappropriate regardless of other factors

If the goal is fat loss, which adjustment in MFIT is most effective?

• Maximize intensity, minimize time

• Moderate intensity, longer duration, regular frequency

• High intensity only once a week

• Eliminate mode variety

Which MFIT-based prescription best integrates both cardiovascular and muscular endurance?

• Jogging + resistance circuits, 3–5x per week, moderate intensity, 40 minutes

• Sprint intervals only, daily, high intensity, 10 minutes Sprint intervals only, daily, high intensity, 10 minutes

• Stretching only, daily, low intensity, 15 minutes

• Strength max lifting, 2x per week, high intensity, 20 minutes

A fitness instructor is evaluating two programs:

• Program A: 2x per week, high intensity, 15 minutes

• Program B: 4x per week, moderate intensity, 40 minutes
  Which is more effective for general fitness, and why?

• Program A, because intensity matters most

• Program B, because balanced frequency and time improve adaptation

• Both are equal since mode is not defined

• Neither, because MFIT does not apply
