Have you even been scared or really excited and you can feel your heart beating out of your chest and you can hear it thumping? This is because these events trigger adrenaline to be released into your body. Adrenaline causes your heart rate to rise and your heart to contract harder. You may also notice that when you exercise such as running, biking, or weight lifting your heart will beat faster too! So for the next week or two I am going to be wearing a heart rate monitor and will be recording my heart rate at different times while resting. I will also be recording my heart rate during events that spike adrenaline such as being scared. I will record my heart rate while exercising too. I want to compare the heart rate by adrenaline with the heart rate by exercise because I am not sure which one will be higher or the most consistent.
A few years ago I had nerve surgery on my shoulder. My nerves died because of an accident skiing. You may ask what the big deal is if your nerves are not working, and that’s what I thought too but that is totally wrong. What happens is the nerves send out electrical signals to tell your muscles to move and work. So when your nerves do not work then your muscles do not either, so my muscle started to die also. So to fix this they took a nerve out of my tricep and placed it into my shoulder to get it working again. The problem that I had with the whole deal is how they test to see if your nerve is working. They use a needle with a cord coming out of it that is attached to a computer. Once they place this needle into your injured area (which really hurts) they move it around and make you flex! This need then reads the electrical signals and shows it on the computer. I think that there should be a device that would be able to detect nerves and their electrical signal kind of like an x-ray detects bone.
