Slide 1

Flip around The Beat By Michael Bellamy and Jacob Lee Mrs. Garrett's Class Phenix City Intermediate School Phenix City, Alabama 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 2

Background Information Cardiac yield is what number of milliliters of blood your heart pumps in one moment. Blood conveys oxygen to your mind and muscles. Oxygen is utilized by your body for development and different capacities, for example, assimilation. The heart, lungs, and veins work distinctively on Earth and in space, so this implies the cardiovascular yield will be diverse on Earth and in space. The human body needs more oxygen to fuel the muscles when it works out. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 3

Objective Recording and examining information, utilizing the logical strategy to explore an issue, and increasing entire numbers. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 4

Things that Affect your Heart Cardiac yield decides your heart and cardiovascular framework's wellbeing. Your heart yield can be changed in the event that you smoke, drink, or utilize some other medication. These things will make your heart rate diminish, in this way, creating unpredictable breathing and heart issues. In the event that you practice consistently, your heart will become more grounded, and your cardiovascular yield will increment. This could have a positive effect on your body and you would have less danger of heart issues. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 5

Question How are cardiovascular yield and practice related, and how does being in space influence your body amid work out? 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 6

Stroke Volume Stroke volume is the measure of blood pushed through the heart amid every pulse. It is measured in milliliters per beat. It regularly stays at around 75 milliliters for each beat. In a head-down tilt position, the stroke volume increments to around 90 milliliters for every beat, since liquids race to the upper part of the body and after that the heart has more blood to compel out with every beat. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 7

Hypothesis Our speculation is that in space, our cardiovascular yield will be more noteworthy than it is on Earth, on the grounds that the heart would work with more prominent exertion and less results. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 8

Materials Watch or clock with a second hand Chair Data sheet Calculator (if needed) 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 9

Locating Your Pulse To find your heartbeat, you put your forefinger and your center finger on the carotid supply route, situated in favor of your neck. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 10

Procedure (Part 1) Sitting in a seat, take your resting heart rate. (Take beat for 10 seconds, then duplicate by 6.) Record resting heart rate in information graph. Figure resting cardiovascular yield by increasing stroke volume times heart rate. Utilize 75 ml/beat for stroke volume. (Cardiovascular yield = stroke volume X heart rate) Record resting cardiovascular yield. Stand and do 25 hopping jacks. Take your heart rate quickly after work out. Record information. Compute your heart yield after work out. Record information. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 11

Procedure (Part 2) Lay your seat down and take your resting beat. Next, take your heartbeat and duplicate it by six to get your heart rate. At that point take your answer and increase it by ninety, which is your stroke volume, and get your space reproduction appraise. After this, make your practice evaluate by making a bouncing jack movement a quarter century in the leaning back position, take your heartbeat, and compute as you did some time recently. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Results 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 13

Our First Table 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 14

Results Next, we reenacted the action as though we were in space. We did this by figuring in a head tilt position, however as opposed to utilizing 75, we utilized 90 for our stroke volume. These outcomes are uncommonly higher than our last results! In our mimicked space, we utilized an indistinguishable strategies from we did with the ordinary test. Despite the fact that it was somewhat dubious to do a head tilt work out, we got strong results. Our outcomes were up to 22 liters for each beat in a head tilt practice position than in a consistent position. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 15

Our Second Table 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 16

Surprising Results It's amazing how much blood your heart pumps a moment. For example, one of us pumped almost 22 liters of blood in a moment subsequent to working out. The heart is a capable muscle surely!!! 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 17

Conclusion During this trial, we took in a considerable measure about the heart and how capable it is. We now realize that in space your heart needs to work much harder. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 18

Importance This information could be connected to restorative science in a way that cardiologists can gauge how much time space travelers can remain in space at one time. This investigation can spare lives by recording data on the heart and cardiovascular yield, which could give data to the VAD, which is the name of the rocket pump part that works with the heart to spare lives while you sit tight for a heart giver. 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Slide 21

Students' Comments I making the most of today's presentation. I got drained, however I had a great time. - Joah I discovered that you locate your cardiovascular yield by your heartbeat. I discovered that its diverse in space and after work out. - Jerica I figured out how to discover my heartbeat. –Jaycie The best part was doing the activities and after that Math. – Terrence 2005 Student Symposium Phenix City Intermediate May 14-17, 2005

Having Fun Not just did they practice their bodies, they practiced their vocal ropes! 2005 Student Symposium Phenix City Intermediate May 14-17, 2005
