Chapter 9, Problem 11CT

Summary Introduction

Case summary:

In the given condition the following sets of experiments were conducted;

Experiment A- The subjects were asked to run for 30seconds and then told to sit down and relax.

Experiment B- The subjects were asked to run while holding their breath during running.

In both the conditions, the depth and rate were analyzed.

Adequate information:

The depth and rate of respiration depends on the physical stress that a body is subjected to. So, in the given conditions, due to the different levels of stress on the body, the depth and rate of respiration will vary.

To determine:

The basis of respiration depth and rate increase in a person subjected to physical activity in different conditions.

Given information:

The depth and rate of respiration of two sets of people are observed. One set of people were asked to run for 30 seconds and then allowed to relax. The other set of people were asked to run with their breath held followed by relaxation.

Introduction:

The process of respiration involves inhalation and exhalation. Inhalation is the process of intake of oxygen rich air, while exhalation on the contrast is expiration of carbon dioxide. The rate of this process is termed as respiration rate which may vary depending on conditions such as; health, age and physical activity.
