What is Physical Activity?

Physical activity is any movement that uses energy from your muscles. It includes walking, sports, housework, and exercise. Regular activity strengthens your heart, improves mental health, builds strong bones, and helps control weight.

Activity Categories:
Light (< 3 METs) + Moderate (3-6 METs) + Vigorous (> 6 METs) = Total Daily Activity
📝 Daily Activity Example:
Light: Sitting quietly, light housework (30 min)
Moderate: Brisk walking, gardening (45 min)
Vigorous: Running, swimming (25 min)

Total: 100 minutes active

The World Health Organization recommends 150 minutes of moderate activity or 75 minutes of vigorous activity per week for adults.

MET Values and Calories

MET measures the energy cost of activities. One MET equals resting energy use. Higher MET values mean more intense activities that burn more calories.

Calorie Burn Formula:
Calories = MET × Weight (kg) × Duration (hours)
📝 Example:
Running (8 METs) × 70 kg × 0.5 hours = 280 calories

MET values help compare activities and estimate calorie burn accurately.

WHO Activity Guidelines

The World Health Organization provides evidence-based activity recommendations for health and disease prevention.

Adults (18-64 years):

  • 150 minutes moderate-intensity OR 75 minutes vigorous-intensity per week
  • Muscle-strengthening activities 2+ days per week
  • Break sedentary time with short activity bouts
📊 Meeting Guidelines:
Option 1: 30 min brisk walking, 5 days/week
Option 2: 25 min running, 3 days/week
Plus: 2-3 strength training sessions

Activity Intensity Levels

Activities are classified by intensity based on MET values and how they feel.

Light Intensity (< 3 METs)

Minimal effort, can sustain for long periods. Good for beginners.

  • Examples: Slow walking, light housework
  • How it feels: Easy to breathe and talk

Moderate Intensity (3-6 METs)

Increases heart rate but allows conversation. Foundation of fitness programs.

  • Examples: Brisk walking, cycling, dancing
  • How it feels: Can talk but not sing

Vigorous Intensity (> 6 METs)

Significantly increases heart rate and breathing. Builds endurance.

  • Examples: Running, swimming laps, HIIT
  • How it feels: Difficult to talk

PAL and TDEE Explained

Your Physical Activity Level (PAL) determines your Total Daily Energy Expenditure (TDEE) – total calories burned daily.

TDEE Formula:
TDEE = BMR × PAL
📊 PAL Categories:
1.2 Sedentary: Desk job, little exercise
1.55 Moderately Active: Moderate exercise 3-5 days/week
1.725 Very Active: Hard exercise 6-7 days/week

Example: BMR 1,500 × PAL 1.55 = 2,325 calories TDEE for weight maintenance.
