The results in the experiment indicated that both respiration and pulse increased with higher activity levels. The range in the results could be explained by different levels of strenuous activities, some requiring more oxygen, and by different levels of fitness among the subjects. The mean results support the hypothesis. The body systems did react to the increase of action because the more the activity was demanding, the more the body metabolic mechanism evaluated had a severe and higher result. The hypothesis was also supported because while doing the experiment we noticed that the results changed immediately when the level of exercise attempt was more demanding than the previous actions. The body reacted very quickly. The data observed in the charts were an average for a healthy teenager and it helped to understand how each system works together to make our body adjust to various types of fitness.
