Heart Rate

[HellokittyCupcake]

Hello, I have a question about my science fair project.

Well, i am doing my report right now and i have a question to ask you.

my topic is: What is the average heart rate when performing
different activities and exercises in a certain
period of time?

My question is: how does my project relate to real world problems or situations? and how is it beneficial to our world and future?
Thank you..

"the average adult human heart beats at about 70 bpm (males) and 75 bpm (females); however, this rate varies among people and can be significantly lower in endurance athletes."- this is because athletes build their stamina and endurance as they train in excessively challenging activities, so the body acclimates.

"The infant rate of heartbeat is around 130-150 bpm, the children's heart beat is 100–130 bpm, the older child's about 90–110 bpm, and the adult's about 60–100 bpm ."

Those heart rates indicate the average heartbeat in a given period of time when the person is at rest-meaning they are not doing anything excessive with their bodies.

The heart rate varies with different activities, technically speaking, the heart rate will increase as the intensity level of activities increase.
You must remember that the heart is a muscle and like any other muscle in our body the heart can contract and expand faster or slower depending on what we are doing.

Your topic relates to real world problems in that the heart must be kept at an optimum range in order for the body to function without problems. Heart attacks result when the heart expends too much pressure and the heart stops. That is why exercise is key because it trains the heart to work much stronger and keep the heart working hard and strong. Certain people lacking daily exercise are prone to heart attacks because their heart is at dormancy and so the heart does not build up a resistance to pressure and activity. The heart must gradually build as a muscle to pump blood stronger and with greater efficiency throughout the body. Patients whose heart rate are above 70 beats per minute have significantly higher incidences of heart attacks and hospital admissions and the need for surgery. Educating people about the optimum heart rate and how we can act to provide that stability is key to a heart-attack-free society.

Hello,

JinSoul already gave you some great information for your report! Since I work in a physiology lab and we study heart rate in animals, I thought I'd add some information.

One thing that relates directly to heart rate is metabolic rate, or the rate at which an animal or human uses energy. By looking at changes in heart rate during different activities, you can predict the relative difficulty of the activity - higher heart rates usually mean that the activity is more difficult. Also, in this day of people trying to get the most benefit in the least amount of time, you can predict the relative amount of energy used for each activity. For example, many of the cardiovascular machines at the gym (treadmills, stationary bikes, and ellipticals) can measure your heart rate while you exercise, and use that to tell you how many Calories you burned during the exercise.

As JinSoul pointed out, cardiovascular (heart) health is extremely important in our society. Heart attack is one of the major health problems experienced by Americans. Doing activities that strengthen the heart by challenging it (with increased heart rate during the activity) are very important to people's long-term health. You can identify activities that people can do to increase their health, which is very beneficial to our world and our future!

Please let us know if you have any more questions as your project progresses.

Good luck!
