THE STUDY OF LUNG VELOCITY UNDER DIFFERENT CONDITIONS
Natasha C 2013-2014

**ABSTRACT **
The purpose of this study was to determine which activity made each student have the least lung velocity. The unit that was used was liters per second (L/sec.) The lungs breathe in and out, meaning they expand and contract. The muscles also get tired after running so the heart pumps blood to the muscles. Different activities were tested on different students (gender) and L/sec was recorded. It was determined that the girls had the least L/sec when they held their breath (0.58 L/sec). Doing the hardest activity clearly made the body tired and wanted to have the least L/sec.

EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS
An improvement to this experiment would be to make sure after the test subject runs or does the activity, has a limited amount of time to breath into the lung velocity probe. The time between the activity and breathing into the lung velocity probe should be the same for each person. The amount of time between the activity and breathing into the lung velocity probe would be controlled, and it would not effect the outcome of the experiment. In order to expand the idea of this experiment, different ages and weight could be tested to determine if they have lower lung velocity.
