How does heart rate lower during cardio? (serious)
How does heart rate lower during cardio? (serious)
So I ge to the gym and its my day to run 2 miles on the treadmill. I get on the treadmill and slowly speed up til ig et to around 8.5 mph and then i begin jogging at a good pace, i check my heart rate ( My first time running in awhile). Its goin pretty fast, and im breathing hard, then about 5 minutes later, i look down at the heart rate monitor to see my heart rate has actually dropped abotu 10-15 beats and im breathing much more easily, even though im still running at the same speed.
what happened? Could i be my body adapted that quick?
That happens to me sometimes when I go on long runs of 10 miles, usually if I'm going at a hard pace I'll be breathing pretty hard but on the second half of the run going the same pace, my breathing has drop significantly. I'm not sure why it happens, reps for answers?
i dont see how it lowers DURINg cardio, but exercise lowers your resting heart rate

My guess would be that since the nervous system controls your rate of 'ventilation'... at first your body had to adjust/adapt to your external surrounds + the exertion of exercise that your body had to reach homeostasis by adjusting the rate and depth of breathing so arterial blood oxygen conc. & your CO2 conc. were hardly altered... plus taking into account your vo2 max (maximal o2 uptake during aerobic exercise for your muscles) - would explain the transition during cardiopulmonary fitness activity such as what you were performing.
I'm only a student, though... so my take is limited.
Sometimes it drops down if I urgently need to fart/burp. Then it speeds up again
how were you measuring your HR? You'd be to be connected to an EKG to adequately measure your QRS (ventricular depolarization) to determine your BP (systolic/diastolic)....

I'm only a student, though... so my take is limited. That happens way too quickly though (in my opinion)
Ill be looking this one up, Id like to know also, since it doesnt make any sense (although in my opinion it was probably an error on the pulse machine)

Ill be looking this one up, Id like to know also (although in my opinion it was probably an error on the pulse machine) Your body works just like a central air system in your home would... you reach a maximal exertion level... your body will go through a negative or positive 'reaction' to counter balance whatever imbalance you were exerting upon the body (intentionally or unintentionally)
re-read what I wrote and see if it makes sense.
that is very possible.
i was thinkin alon gthe lines of ur body is in decent shape, but it isnt used to the running, and when u start running, your body is trying to adapt to the amount of oxygen it provides to the body. After the strenuous exercise, the body is forced to put more oxygen out in order to keep ur body functioning. THerefore More Oxygen = Less breathing = Easier Heart beats = Lower heart rate.
but idk lol, i am only 15 :(

re-read what I wrote and see if it makes sense. I know man dont worry Im a biochem/physiology double major. There would be no reason for his heart rate to drop, especially since hes kicking it from the anaerobic to the aerobic respiration stage. If anything, it should be low at first, then high when the oxygen demand is there.
And what I meant was that the peripheral chemoreflex is too fast for there to be a heart rate change of that magnitude. Your body would adjust its ventilation almost instantaneously according to the demand, it wouldnt go "overboard" (hence reducing cardiac output)

but idk lol, i am only 15 :( your body, physiologically, just can't "up" your VO2 max (max oxygen uptake during aerobic activity), but this is just a 'theoretical' value... differentiated from 'peak oxygen uptake' which is an actual measure.
I assume it's just because your body is "warmed up" yet. After all, a lower pulse rate means that your heart has to do less work to pump blood around the body. I know that when I wake up in the morning and try to run, it doesn't take much for my heart to be racing. If I wait until night time it's easier on my heart.

Your body would adjust its ventilation almost instantaneously according to the demand, it wouldnt go "overboard" (hence reducing cardiac output) props to you, mate. Yeah -- that's the rationalization of your cardiopulmonary activity/fitness , but I'm just picturing the tidal volume moved during aerobic activity based on his arterio-venous o2 differential's effect on cardiac output based on what was stated above. Makes sense, no?

Makes sense, no? Perhaps you have to explain what youre saying a bit better, I dont quite get what youre trying to say. Dont worry about being overly complicated, just make sure its accurate (for example, "arterio-venous 02 differential effect on cardiac output" doesnt make too much sense)
My educated guess at this point would be that its a hormonal thing. The endocrine system seems to be the only thing that could induce change over a "long" time like this. Your adrenaline was probably high during the initial stages of exercise, due to shock on the body, which increases the contractile rate of the heart, and in turn increases cardiac output. Your body would then respond to the change in various metabolites and gases and alter the cardiopulmonary synchronization to re-achieve homeostasis, and thus lower the heart rate to a level that is needed
found this quote, seems to agree
The almost instantaneous increase in heart rate to increased demand for cardiac output results from a fall in vagal tone and from the release of noradrenaline from sympathetic fibres, mediated by BI receptors. The humoral component (adrenaline) takes some minutes to operate, but may have altered in anticipation of an increase in demand for heart rate due to behavioural responses
mine does the same thing, it happens to everyone i think. if you ever notice(for me atleast) the first 10 minutes of running sucks, but after that you get into a zone and you just ride it out.
i think of it like a car, it takes more effort to get the car going from a stop light, but once it has warmed up and cruising at a constant speed it uses less energy to keep it going.

maybe it is like our body's adaptation to previously being in shape. Such as when u were in shape ur body learns to providee more oxygen per heart, therefore, it takes less heartbeats to live. However, after taking a long rest/break. However when u start to run, ur body is used to providing itself with only the amount nedded to get u to run. However but due to muscle memory, it start to condition back to beating with less and provinding mroe
