According to the document, an experiment was conducted to determine whether jogging at 3 mph for 30 seconds or doing sit-ups for 30 seconds would make the human heart beat faster. The hypothesis was that jogging would make the heart beat faster, but the results showed that sit-ups actually made the heart beat faster, likely because the jogging pace was a slow walking speed. The document provides information on an experiment comparing the effects of light jogging versus sit-ups on heart rate.
