BREATHING By the end of this lesson, I will be able to: Know what tidal volume is. Understand the effects of exercise on breathing.

How much air do we breathe? Use Page 70 Write a definition for: 1.Tidal Volume 2. Respiratory Rate 3.Vital Capacity Q 1. What happens to tidal volume during exercise and why? Q 2. Why is Vital Capacity important to sports people?

Vital Capacity, forced breathing, normal breathing

Effects of training on breathing Breathing muscles grow stronger which allows deeper breaths.

Lungs and Exercise When we exercise, our heart and lungs have to work harder. Q1. What happens when you heart and lungs work harder? You may want to use a diagram as follows:
