 * THE STUDY OF HOW DIFFERENT BODY POSITIONS AFFECT HEART RATE**

Cary Academy

**ABSTRACT** The purposes of these experiments were to determine how different body positions affect heart rate. The heart is an organ made of cardio-vascular muscle that pumps blood through the body. In the experiments, heart rate was tested in three different body positions, which were sitting, standing and crouching. Crouching had the lowest heart rate, while standing had the highest heart rate. This probably happened because when the body is folded up, like in crouching, it is harder for the body to pump blood.

**CONCLUSION**
In the end, crouching had the lowest heart rate out of the three body positions. These results are important because they let people know that crouching relaxes heart rate the most. After running, people will know what body position helps most to reduce heart rate. The hypothesis was correct because it was hypothesized that different body positions would affect heart rate. However, It was not hypothesized that crouching would relax heart rate the most. It was assumed that since crouching used the most muscles, it would bring up heart rate. Some experiments that could be done in the future could test different body positions and measure heart rate.
