Graphs

This is the graph I got after using some hand-grip heart rate monitor: This is it redone in excel.



How to use the hand-grip heart rate monitors: First, connect the the wireless receiver to the interface, after the Logger Pro is opened up, you take the hand-grips and grasp each of them in each hand and start the data collect. There will be two graphs, the one on the top is for showing what your heart rate is every five seconds, while the one on the bottom shows each individual heart beat as you record.

Good side: You can grip the heart rate moniters and not have to use the chest strap one where actually have to put the chest strap on and it becomes very uncomfortable, and sweaty.Its relatively easy to use the hand grips because all you have to do is grab the hand grips and it measures your heart beat.

Bad side: The signal strength is horrible and it forces you to have to line up arrows on the hand grips and you have to keep the receiver and hand grips very close to each other, and sometimes the signal will break off.

Possible experiments with heart rate monitors: 1.) Have two people, one person being in good shape and the other being fat or obese. You would then use the heart rate monitors to see how each person's heart beats in different conditions and situations. There would be 4 main tests, having them run, sit still, sleep, and hold their breatha and see how each of their heart of their heart rates differ from one another.

2.)Have a few people, each person being from a different age group, and put them through 4 different tests, having them run, sit still, sleep, and hold their breath and see how each of their heart of their heart rates differ from one another.

How to use the EKG:

There are 3 differently colored alligator clips and you get three already provided sticky pads and attach the pads to the clips. You then put the green and red clips with the pads on two separate parts of your body, after that you put the black clip with the pad on the same side of your body as the green clip but in a lower place. You can then start the data collect and what the EKG does is it measures the amount of electrical activity someone's heart produces over time. The pads I was talking about before are electrodes and they measure the electricity given off by your heart on the the skin and the electrodes naturally will conduct the electricity produced by your heart.

Additional notes: Although it is hard to read the graphs the axes can be changed so that the graph can be more easily legible.

Possible experiments:

1.)You can test different people of different age groups to see how each age groups heart produces electricity.

2.)Someone could get someone else to drink large amounts of caffine and see how that affects the graph.

3.)A person could be asked to exercise for a certain amount of time and then then hook them up to the EKG and see how that affects their heart's release of electricity and see how much different the graph looks.
