Idi ti A Yipada: Nọmba Froude

Froude Number (Fr) = v² / (g × L)

Where:
  v = hiking speed (m/s)
  g = 9.81 m/s² (gravitational acceleration)
  L = leg length (m, typically ≈ 0.53 × height)

At Fr ≈ 0.5, the inverted pendulum model breaks down

For a 70 kg person hiking 5 km at 1.3 m/s (4.7 km/h):
  CoT = 0.50 kcal/kg/km
  Total energy = 70 kg × 5 km × 0.50 = 175 kcal
  Time = 5 km / 4.7 km/h = 63.8 minutes

Same person running 5 km at 2.8 m/s (10.1 km/h):
  CoT = 0.90 kcal/kg/km
  Total energy = 70 kg × 5 km × 0.90 = 315 kcal
  Time = 5 km / 10.1 km/h = 29.7 minutes

Running burns 1.8× more total calories but in half the time.
For weight loss: Hiking 5 km = 175 kcal; Running 5 km = 315 kcal

For cardiovascular health, these are roughly equivalent:

Option A: Hike briskly (≥100 spm) for 30 minutes
Option B: Run moderately for 15 minutes

Guideline: Running provides ~2× cardiovascular stimulus per minute
Therefore: 150 min/week hiking ≈ 75 min/week running

Aṣayan ti o dara julọ da lori ọrọ-ọrọ kọọkan:

If: Current fitness = low OR injury history = yes OR age >60 OR joint pain present
Then: START with hiking, progress to brisk hiking (≥100 spm)
Goal: Build to 30-60 min/day at moderate-vigorous intensity

If: Current fitness = moderate-high AND injury-free AND time-limited
Then: Running provides greater cardiovascular stimulus per minute
Goal: 20-30 min/day at moderate intensity OR 10-15 min at vigorous

Ideal for many: Hybrid approach
  - Primary: 3-4 days running (cardiovascular stimulus)
  - Secondary: 2-3 days brisk hiking (active recovery, volume)
  - Result: Higher total weekly activity with lower injury risk
