What does MET stand for and what is its primary use in conditioning programs?

• A. Metabolic Equivalent Task; expresses energy expenditure as multiples of resting metabolic rate to guide exercise intensity.
• B. Maximum Exercise Threshold; measures peak effort capacity.
• C. Mechanical Efficiency Trial; assesses efficiency of movement.
• D. Metabolic Efficiency Test; estimates caloric cost during activity.

Answer: (A)

The key idea here is understanding what MET represents and how it’s used to guide exercise intensity. MET stands for Metabolic Equivalent Task, and it expresses the energy cost of activities as multiples of resting energy expenditure. One MET equals the energy your body uses at rest (about 3.5 ml of oxygen per kg per minute). This unit lets you compare how hard different activities feel for different people and organize workouts by intensity: light (around 1–2 METs), moderate (about 3–6 METs), and vigorous (more than 6 METs). In conditioning programs, you pull on METs to prescribe the right intensity for a client, adjust the workload, and track progression. You can also estimate calories burned with a rough formula: calories per hour ≈ METs × body weight in kg × 1 kcal/kg/hour.

Other options don’t fit because they don’t define MET or its primary use in training. They refer to concepts like peak effort thresholds or efficiency tests, which are different ideas from how METs quantify and guide exercise intensity.
