What is the effect of resistance exercise on cardiac output at maximal effort?

The effect of resistance exercise on cardiac output at maximal effort typically results in minimal to no change. During resistance training, the cardiovascular response includes increases in heart rate and blood pressure; however, the nature of the exercise (mostly short bursts of high intensity) often leads to a less pronounced increase in overall cardiac output compared to aerobic exercise.

While aerobic exercise, such as running or cycling, tends to significantly elevate cardiac output due to longer durations of continuous exertion, resistance training usually emphasizes shorter, more intense efforts that do not sustain the same level of cardiovascular response.

The peak demands placed on the cardiovascular system during resistance exercises may not require a substantial increase in cardiac output because the muscle groups involved can lead to temporary reductions in blood flow and vessel dilation in other areas, balancing out the overall effect. Thus, the correct understanding reflects that though there may be some increase in heart function during resistance training, the overall effect on cardiac output at maximal effort tends to show minimal alteration.
