If someone begins intense cardio training and develops their heart muscle, it seems to me that the increase in volume of blood that the heart can pump with every beat might manifest as a higher systolic blood pressure. Is that right? If not, why not?

1If that were true then athletes would tend to have hypertension and sedentary individuals would tend to have low BP. What has your research revealed about that?– Carey Gregory ♦Commented Nov 4, 2020 at 15:08

@CareyGregory For some reason I hadn't tried searching Google for that, but I just did a quick search and it seems to confirm my suspicion: runnersworld.com/health-injuries/a20846111/… "If you break the results down further, you find that strength-trained athletes have slightly higher blood pressure than endurance-trained athletes." I have been doing serious weight training for the past few months and my systolic blood pressure is now averaging around 130, and I was trying to figure out why, as I don't fit into any of the risk groups.– Nathan WailesCommented Nov 4, 2020 at 15:39

Interestingly, I just checked a doctor's report from a check-up I did just before I started the weight training when I was ~10lbs heavier than I am now and my systolic BP was lower (126) while my diastolic was much(?) higher (76 back then, avg. ~63 now).– Nathan WailesCommented Nov 4, 2020 at 17:29

1Your question would be greatly improved (and meet site requirements) if you added the link in your comment to the question itself. The question should contain everything necessary to understand it and see that you did prior research. Reading comments shouldn't be necessary.– Carey Gregory ♦Commented Nov 5, 2020 at 0:59

Intense cardio training over sufficiently prolonged time tend to incerease the capacity of your cadiovascular system to carry oxygen to the muscle. One aspect (among many) is the increase in volume of the left chamber of the heart which is seen in professional athletes of enurance sports. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4771151/) Blood pressure rises in excercise (not easy to measure, but can be observed in stress tests, https://www.ahajournals.org/doi/full/10.1161/hs0901.095395) to accomodate the need for extra oxygen. As the excerise continue, the arteries diameter get larger and it helps in regulating the blood pressure. It suppose to go back to normal as exercise stops and it actually goes lower than usual (https://www.ahajournals.org/doi/abs/10.1161/01.cir.83.5.1557 since the blood vessels remain large. You can also test it on yourself) for a few minutes after stopping. Prolonged aerobic training helps to reduce hypertension.
