Lab 14: Physical Fitness and Respiratory Function

A black dynomometer laying on table.

Chapters 18 and 21

In this week's lab students examine respiratory function. A member from each group will wear a respiratory belt that records normal breathing and then perform various tasks so everyone can observe the effects on the respiratory rate and depth. Students will also obtain graphs that allow them to measure different lung volumes as well as the elasticity of their lungs.

Two pieces of test equipment.

These tests include testing grip strength, measuring flexibility and body fat composition, and determining aerobic fitness during the Forest Service Fitness Test. From these results students can determine their overall fitness score.

Topics to Review Before Lab:

  • Flexibility
  • Cardiorespiratory endurance
  • Muscular strength
