Introduction Bodies rely heavily on oxygen consumption to power all processes, internal or external, and the more work being done, the more oxygen is needed. Lung capacity regulates how much oxygen is taken in to diffuse into our cells for energy conversion. Lung development is dependent on gender, age and intensity of physical activity (Lazovic et al., 2015). Lung expansion can present respiratory muscle strength, overall lung function and health advantages yet it is constantly overlooked as a determiner of health (de Merdeiros, Fuzri, Rattesa, Brandão & de Melo Marinho, 2017). A recent study has shown data that supports the relation between lungs and health. Talwar et al. concluded that patients in their study had improved in time and…show more content…
The program recorded liters of air over 120 seconds per trial. Once the program was running, the students clipped their nose to maximize the reading by minimizing nasal inhalation and exhalation. With their arms braced against a flat surface, a trial run was completed and the sensor was zeroed once the student was set. Without moving the sensor, the student completed four complete regular breathing cycles. A maximum inspiration and expiration were recorded to measure the vital capacity of the students’ lungs. The maximized breath was followed by a few cycles of recovery breaths. Data displayed by Logger Pro was analyzed to determine total lung volume and individual scores were added to the Life Science Core database. Results The Life Science Core provided a database that performed a t-test on all the students’ inputted data. For this experiment, data between individuals who identifies as ‘yes’ swimmers and ‘no’ swimmers in the demographics quiz were compared. A total of 57 swimmers averaged a lung capacity of 6.199 L with a standard deviation of 2.7532 L. A group of 984 non-swimmers averaged a total lung capacity of 6.267 L and a standard deviation of 2.2391 L. The database calculated a t-value of 3.01 and a corresponding p-value of 0.003 with 1039 degrees of freedom. Discussion Analyzing the data, the results prove to be statistically
