Lung Capacity Fitness Level

Extracts from this document...

Introduction

High Level Biology Human Physiology 1 Digestive or Respiratory System Open Investigation Will increasing levels of fitness enable one to have larger vital lung capacity? DESIGN Background Information Notice how short distance professional swimmers, for example, a 50m freestyle swimmer, breathe only once or twice throughout the whole course. Why is it that it is nearly impossible for normal recreational swimmer to do that? If a person's lung size cannot increase, how is it possible for professional swimmers to have such large lung capacity thereby able to hold large amount of air? The answer has to do with fitness level and exercise. Breathing comprises of two actions, inspiration and expiration. Breathing is one of the required bodily functions of human beings. Our lungs deliver oxygen breathed in (inspire) from our surrounding air into the blood inside our body, and contrary exhale (expire) carbon dioxide out of the body. When inspiration occurs, the diaphragm and the intercostal muscles contract and causes the diaphragm to move downwards, increasing the volume of the chest cavity. The intercostals muscles also causes the rib cage to expand, further increasing the volume. Contrary to inspiration, expiration causes the diaphragm and intercostal muscles to relax therefore the thoracic cavity returns to its original volume, increasing the air pressure in the lungs and forcing carbon dioxide to be released from the body. [4] Diagram 1.0: The act of Inspiration and Expiration [6] We know that our lungs respond to our body's changing needs for oxygen. We breathe deeper and take faster breaths when our body is associated with vigorous exercise. Our lungs are the organs that perform all our critical breathing functions. As mentioned before, professional athletes attain a larger lung capacity than normal people. Lung vital capacity is the maximum volume of air that can be forcefully exhaled and inhaled in one breath. [6] Vital Capacity = IRV (inspiration) + ERV (expiration) ...read more.
