Reserch question

How does increasing physical activity while holding your breath affect your heart rate and heart recovery time?

variables

indepedent

amount of phisical activity

dependant

heart rate (bpm)

recovery time (sec)

controled

Breath-holding durationresting period before each test environment time of day measurement

how will the experiment be done

step 1:find people to do the experiment and set up the hear rate monitor to the computer

step 2:Measure the person's resting average heart rate (bpm). Then the person will hold their breath for 20 seconds, and their average heart rate will be noted down in an Excel sheet. Recovery time to normal heart rate will be measured with a chronometer. They will then do 15 jumping jacks while holding their breath, and their heart rate will be measured, as well as the recovery time. Then, the same person will do 30 jumping jacks while holding their breath for 20 seconds. Heart rate will be collected as data, as well as their recovery time.

step 3:data will be collected and compared to see if the independed variable changed something in there breathing

materials

-heart rate monitor

space in room

similar tempetuare rooms

timer

computer for data collection

WHY the expirement

While talking with a student, we all know that physical activity will increase a person's heart rate, but we were debating if, while having low oxygen levels, would your heart need to work faster or slower to process the oxygen to produce energy.

hypothasis

i I believe that because of the low amounts of oxygen, the low oxygen will have to be processed at a faster rate in order to continue producing energy for the entire body, so the heart rate will be faster. Also, more demanding exercises will need more energy, meaning that if the heart does go faster, the more demanding the exercise, the faster it will go because more demanding exercises require more energy.

the online application i used to track my data

the tool i used as messurment

original data heart rate levels

activity one 20sec holding breath

activity two 20 seconds holding breath and 15 jumping jacks activity 3 20 seconds holding breath and 30 jumping jacks

feedback loop (negative)

Holding your breath is a negative feedback loop because of the CO₂ in your body. Your body reacts to counter the change, and it increases heart rate. Once someone stops holding their breath, it also increases their breathing rate. This is because once you start breathing again, oxygen levels stabilize, and CO₂ is expelled, bringing the body back to homeostasis.

Although holding your breath is a negative feedback loop, it could be a positive one in very extreme cases because a positive feedback loop is meant to amplify something instead of correcting it. If holding your breath caused a chain reaction and your body kept increasing CO₂ levels without correcting it, that would be a positive feedback loop.

conecting to real life

this feedback loop is usefull in are lives for exsample when we are swimming and we are running out of air are body is probably tring to tell us that the co2 leves are to hight and we need oxigen to produce for energy and thats why you go for air if are body would not give use this signals we would probably die from lack of oxigen or to much co2 in our body

conecting to other systems

musculatory system when holding your breath for a long amout of time your body will use myoglobin witch is stored in your muscles for movement and used when oxygen leves are low in the body another system witch holding your breath inpacts is the digestive system slowing it down beacuse the body will prioritize sending energy to the brain and muscles slowing down the digestive system

altough i felt the expirement going well there is room for inprovment

we did not track participents previus activitys so there can be variables that affect the expiremnet as well there could be posible human erors witch removes 100% accuracy from it

only a 5 person test so evidance such as hight weight and even age are not as clear to be debendent on holding breath while exsersising

hypotasis was correct

showing how the body the more demanding an exersise the more energy needed. its going to need more energy to dothe exserise thats why hear rate accelarates and recovary time is longer

Conclusion

The experiment went great because heart rates were so different between exercises that I can come to a conclusion since the same thing happened for all participants. Although I could not get age, height, and weight sufficient enough to come to a conclusion that they are affected, I did complete my research question, and my hypothesis was right. I got what I was testing for and the result I was hoping for.

for confirmation of my expirement i asked chat gpt to tell me if i did the expirement what would happen and what chatgpt sayed was altough the heart would increse its only during a short duration so maby if i had made people hold there breath for longer it would decrese and that tempeture really afects the expirement so im glad i controled that variable
