=HEART RATE RECOVERY TIME AFTER PERFORMING DIFFERENT EXERCISES= By Emma G. 2012

=**ABSTRACT**= The purpose of these experiments was to see how long it takes the heart-rate to come back to the original heart-rate plus fifteen after doing different exercises for different amounts of time and adding liquids to drink while recovering. Every single sport or form of exercise uses a muscle group to generate some sort of motion and there are three types of muscle which are skeletal, smooth, and cardiac. Mainly the method of all the experiments was to see how long it took for the heart-rate to recover to the original heart-rate plus fifteen while doing different exercises and seeing if different drinks helped recover faster. The results showed that when doing exercises for a longer period of time athletes have a faster recovery time than non-athletes. This is because the athletes are used to exercising for longer periods of time. Also when drinking different types of liquids while recovering, the recovery times varied by drink due to the fact that each drink had different amounts of salt and the amount of salt in the drink matters because athletes need a certain amount of salt while exercising.

=**Conclusion**=

Athletes recovered faster than non-athletes in each experiment because athletes are used to doing exercises for longer periods of time with no breaks and athletes hearts are conditioned to recover quicker, overall athletes are more fit. The results are important to the world because it educates athletes and non-athletes on fitness tips such as which drinks are better to drink while recovering and how exercising for longer periods of time increases the heart-rate more. The hypothesis was correct because athletes had a faster recovery time than non-athletes in each experiment which is because non-athletes aren’t used to exercising for a longer period of time and that was important in the experiments because the volunteers would need more fitness, which the non-athletes did not have. Some follow-up experiments would be are boys or girls more fit, do different energy drinks affect the recovery time and do different energy bars.
