Why the study?
Does the mode of contraction and active muscle mass affect circulatory responses to exercise in healthy men?
Does the mode of contraction and active muscle mass affect circulatory responses to exercise in healthy men?
The magnitude of the pressor response to exercise depends on active muscle mass rather than contraction mode, though the mode dictates the specific circulatory changes (cardiac output vs resistance) driving the response.
No takes yet. Share an insight, caveat, or question.
Muscle mass may predominate over contraction mode in driving pressor responses during exercise testing; leaves open translation to patients with cardiovascular disease.
Lewis et al. (1985) studied this question.
