2.48: Describe Experiments to Investigate the Effect of Exercise on Breathing in Humans

INVESTIGATING EFFECT OF EXERCISE ON BREATHING

DURING EXERCISE, TWO TYPES OF RESPIRATION OCCUR: 1. AEROBIC RESPIRATION 2. ANAEROBIC RESPIRATION Diagram Showing the Different Types of Respiration

METHOD: Record Stationary Breathing Rate of Students per 10 Seconds Students will endure 15 Minutes of Exercise at the Same Intensity Breathing Rate After Exercise is Measured per 10 Seconds Results are Compared

RESULT: After Exercise, Breathing Rate Should Increase as the Muscles are Respiring, More Oxygen is Needed for Aerobic Respiration to Provide Energy for the Muscles to Keep Contracting, Causing the Lung Muscles to contract and Relax More Rapidly and the Heart will Beat Faster to Supply More Blood to Respiring Muscles and Cells
