What We Did
Dependent Variable- Heart rate
Control Variable- Resting heart rate
Constant Variables- amount of time exercising, standing while taking your heart rate, taking your heart rate from your neck
After 30 seconds of jumping jacks and sit ups, the jumping jacks will cause the heart rate to be faster. This
was correct. It will take the heart rate 15-20 seconds to recover. This was incorrect. After doing 30 seconds of jumping jacks and 30 seconds of sit ups, the heart rate was faster after doing the jumping jacks, but, it took longer than 20 seconds for his heart rate to recover and get back to normal. His heart rate after the three trials of doing jumping jacks, his heart rates were 76 BPM, 64 BPM, and 144 BPM. The average was 94.66. The numbers for the 74 BPM, 100 BPM, and 106 BPM. The average was 91. So the average for the jumping jacks was higher. But, the recover times for jumping jacks were, 33, 20, and 45, and the recovery for the sit ups were 54, 30, and 45, making the second hypothesis incorrect. The numbers from the jumping were higher because it was more exerting than sit ups.
