oa Possible Effects of Sport Practice on the Respiratory Volumes and Possible Effects on Heart Rates and Blood Pressure in Adolescent Females

This study was carried out to examine the difference between the respiratory volumes in athlete and non-athlete adolescent females, how does exercise affect the respiratory volumes and how could the effects of exercise on the respiratory system affect the heart rate? Introduction: The respiratory and circulatory systems are the most important systems in the body as they involve vital organs (lungs and heart). They are affected by several factors, which may improve or weaken their function. Exercise positively affects their function. Methods: In this study 2 groups were compared: athletic and non-athletic females using a spirometer to measure the respiratory volumes before and after running. The heart rate and blood pressure were also measured in both groups. The statistical analysis and graphs were done using excel 2007. Results: The pre-test mean vital capacity in non-athletes was 2600.0± 496.7 and in athletes: 2642.9 ± 340.9. Whereas post-test mean vital capacity of lungs in non-athletes was 2385.7 ±429.8 and in athletes: 2428.6 ±407.1. Pre-test mean blood pressure in non-Athletes was 94.6 ± 9.3mmHg and in athletes was 86 ± 8.1 mmHg but post-test mean blood pressure in non-athletes was 113.8 ± 31.6 mmHg and in athletes: 99.1 ± 8.8 mmHg. The pretest mean heart rate in non-athletes was 89±5.2 beat per min while in the athletes it was 86 ± 6.5 beat per min. Conclusion: On the short term exercise increases the heart rate, decreases the blood pressure, decreases the lung capacity and increases tidal volume. Whereas long term effects involve increased lung capacity and tidal volume; and decreased blood pressure and heart rate.
