Number Of Sit-Ups Affect Heart Rate
Internal Assessment
Research Question: How does the number of sit-ups affect your heart rate.
Independent Variable (IV): Number of sit-ups ( 0,5,10,15,20). I chose these 5 increments because they are consistent numbers in which everyone can participate without it being to much.
Dependent Variable: heart rate( BPM) +/- 4 ( number of beats in 15 seconds multiplied by 4).
Materials: timer, flat surface, movable clothing
Background: In this experiment I will test your heart rate and if it increases or decreases with exercise (sit-ups). This is important because everyday you engage In physical activity, this test will show the participants if they increase dramatically with minimal and semi-heavy activity. The higher your heart rate, means the harder it …show more content…
Have participant do 5 sit-ups, then immediately take the heart rate after they have finished. (To find heart rate, have participant put two fingers on their pulse. Time them for 15 seconds and then multiply by 4).
3. Record heart rate and give one minute resting period to participant
4. Repeat steps 2 and 3 a total of three more times, increasing the increment by 5 every time until you have done all increments (0,5,10,15,20)
Example of calculation: Participant 1 counted 23 beats in 15 seconds, calculated by 4, which gives her a heart rate of 92 BPM after doing ten sit-ups.
Data Presentation and stat test: To analyze my data I will find the mean and standard deviation and put it into a scatter plot. I will find the line of best fit, to have an overall consensus of where the majority lie on the graph. I will add error bars which represents the uncertainty or error of the corresponding coordinates of my point.
