Type of the Project : Investigatory
Class : XII (Medical)
Vital Capacity : It is the amount of air which can be maximum inspired and also maximum expired. It varies from 3.5 to 4.5 litre in a normal adult person. It is the sum of tidal volume, inspiratory reserve volume & expiratory reserve volume. [VC = TV + IRV + ERV]. Vital capacity of a lung is directly proportional to its capacity of increasing during ventilation for gaseous exchange. Thus vital capacity of athletes, mountain dwellers than plain dwellers. Vital capacity is more in men than women & in young ones than old person.
Observation
Physical efficiency of a sports man is more than a normal person. Males have more vital capacity than females persons who do not exercise have low vital capacity then those person who do more work & muscular work have more vital capacity.
Hypothesis
Physical efficiency of people is decreasing due to decreases in vital capacity.
Project Introduction
The modern age of medical science has succeed is increasing the life span of man. Vaccines have developed against many deadly disease like Rabies, Chicken pox etc. Many disease like polio, diphtheria considerably controlled.
Science has increased the capacity of a man to fight against many disease but unfortunately on the other hand efficiency of human being going on decreases.
Normally people think that a laughy person is physically fit & a slim can not be fit. But it is not true a laughy person may be physically fit & a slim can be fit. A person who does physical exercise & muscular exercise is more fit than a normal person.
Vital capacity :
The amount of air which we can exhale with maximum effort after inhalation with maximum effort. It is about 3.5 lit. to 4.5 lit. in a normal person.
External Respiration :
It is the intake of O2 by the blood from H2O or air in the respiratory organs and elimination of CO2.
Internal Respiration :
Experiment : Vital capacity for girls
| Sr.No. | Name of Student | Vital Capacity |
| 1. | Neha | 3000 |
| 2. | Priti | 2500 |
| 3. | Reena | 4000 |
| 4. | Monika | 3500 |
| 5. | Divya | 4000 |
Average Vital Capacity = 35%.
Experiment : Vital capacity for sports enjoying girls
| Sr.No. | Name of Student | Vital Capacity |
| 1. | Neelam | 4000 |
| 2. | Dipti | 4500 |
| 3. | Manju | 5000 |
| 4. | Pooja | 4500 |
| 5. | Meenakshi | 5500 |
Average Vital Capacity = 47%.
Experiment : Vital capacity for boys
| Sr.No. | Name of Student | Vital Capacity |
| 1. | Anil | 4500 |
| 2. | Pawan | 4500 |
| 3. | Sunil | 5000 |
| 4. | Pardeep | 5000 |
| 5. | Rakesh | 5500 |
Average Vital Capacity = 47%.
Experiment : Vital capacity for sports enjoying boys
| Sr.No. | Name of Student | Vital Capacity |
| 1. | Amit | 5000 |
| 2. | Vinit | 5500 |
| 3. | Jitender | 4500 |
| 4. | Rajesh | 6000 |
| 5. | Pardeep | 4500 |
Average Vital Capacity = 51%.
Results :
On the basis of experiment it is obvious that vital capacity for girl is less than boys.
On the other hand vital capacity of sports girls is higher than the average vital capacity of girls. As well as vital capacity of sports boys is higher than the average vital capacity of boys.
Now, it is obvious that vital capacity of sport girls and boys is higher than their average vital capacity.
Conclusion
By this project, we can easily conclude that physically active boys and girls have more vital capacity thus they are more energetic.
This project can also be used to check the physical standard of person while recruiting them in forces.
