The effects of external stimuli on your heartrate while exercising.

This study investigates how external stimuli (such as music) affect humans' heart rates while exercising. While it is well known that exercise increases our heart rate, less is understood about how external factors modulate this response. To test this, 10 participants were asked to run on a treadmill for 5 minutes: once while listening to fast-paced music, once with slow-paced music, and once without any music. I monitored their heart rate using smartwatches. The results showed that faster-paced music caused a greater increase in heart rate from rest than while running with no music; however, slower-paced music would have a smaller increase in heart rate from rest than no music. This suggests that auditory cues (such as music tempo) can directly impact cardiovascular exertion during workouts.
