During resistance training in normal adults, how does respiratory rate generally behave?

During resistance training in normal adults, respiratory rate typically shows little change, particularly during short-duration, high-intensity exercises. This is largely because the body is able to efficiently utilize the oxygen it has available during these intervals, and the demand for oxygen does not significantly outpace the rate at which it can be delivered. Additionally, resistance training often involves isometric holds or short bursts of activity, which can limit respiratory rate increases compared to continuous aerobic exercise.

In contrast, options that suggest an increase or significant change in respiratory rate would imply a higher demand for oxygen due to muscle exertion; however, the unique characteristics of resistance training often allow individuals to maintain a stable breathing pattern. Stopping completely is not a viable option during any form of physical exertion, as the body requires a continuous supply of oxygen to sustain muscular activity and metabolic processes. Thus, showing little change accurately reflects the typical physiological response of the body during resistance training sessions.
