Prolonged exercise yields distinct systolic interval shifts in healthy subjects; leaves open relevance for clinical monitoring or diseased populations.
Does prolonged submaximal exercise alter systolic and diastolic time intervals compared to short-term incremental maximal exercise in healthy male students?
Prolonged submaximal exercise induces specific zigzag changes in systolic and diastolic time intervals, driven by early decreases in stroke volume and blood pressure, and late decreases in myocardial contractility.
Nabekura et al. (1990) studied this question.
