Acute Effects of Moderate Continuous Training on Stress Test-Related Pulse Pressure and Wave Reflection in Healthy Men

Abstract

Acute MCT decreased PP and reduces AIx@75 after 60 min of recovery. Furthermore, PP and AIx@75 showed reduced values after completion of MCT indicating attenuated hemodynamic response to stress testing after MCT. Moreover, higher physical conditioning status was associated with more favorable effects on stress test-related arterial compliance.

Effects of cycling bouts performed with different intensities and amounts of energy expended on central pressure and pulse wave reflection in normotensive and hypertensive men

“…To date, most of the available studies have investigated the acute central pressure and pulse wave reflection responses to aerobic exercise in healthy subjects [11,12,22], or using mixed samples, such as 10 prehypertensive and hypertensive individuals [23,24], metabolic syndrome and hypertension [25], and patients with peripheral and hypertensive arterial disease [26], and have reported contradictory findings. A possible explanation for these inconsistent findings may be due to methodological issues, such as no control group (i.e.…”

“…Among the studies that observed acute reductions in central pressure and pulse wave reflection over a 30-min recovery period [11,12,22,33], only the study by Nieman and Dew [33] applied an experimental control. Physiological responses were investigated over a 5-h period following a 2-h treadmill run at 75% VO 2max in trained men ( n = 8; age 39.3 ± 2.3 years;, VO 2max : 54.8 ± 1.7 mL·kg -1 ·min -1 ) and women ( n = 8; age 35.8 ± 2.8 years;, VO 2max : 49.6 ± 1.8 mL·kg -1 ·min -1 ), with significant reductions in AIx@75 restricted to the female runners.…”

“…Among the studies that observed acute reductions in central pressure and pulse wave reflection over a 30-min recovery period [11,12,22,33], only the study by Nieman and Dew [33] ), with significant reductions in AIx@75 restricted to the female runners. Regardless of the findings, the lack of ecological validity of the exercise protocol adopted in this study is evident, especially within the context of training programs for the initial management of hypertension.…”

“…cSBP minus cDBP)] and the augmentation index [AIx (ratio between augmentation pressure and cPP)]. Some studies observed a decrease in pulse wave reflection during the postexercise period [11,12], whereas others did not observe such acute changes [12,13] or noted increased responses after exercise [14]. A question arises as to what could explain these contrasting research findings.…”
