“…Shorter but more intense endurance cycling (6 consecutive days for 2 h per day) resulted in significant reductions in central and peripheral PWV but no change in AIx. 34 Thus, changes in arterial lumen diameter may only be brought about by prolonged training lasting longer than 6 days. Given that arterial stiffness increases with age future studies utilizing prolonged exercise are needed to examine whether aerobic exercise is also beneficial for middleaged and older individuals.…”

The effect of short-term aerobic exercise on vascular function of young individuals with a family history of hypertension was investigated. Thirty young men with a family history of hypertension were randomly assigned to either an exercise (n ¼ 15) or control (n ¼ 15) group. Exercise subjects performed 30 min of supervised cycle training at 65% of their maximal oxygen uptake ( . VO 2max ), three times per week for 4 weeks. Control subjects were asked to maintain their normal levels of physical activity. Peak leg and forearm blood flow were assessed using plethysmography and was determined as the highest blood flow following 5 min of reactive hyperemia. Cardiopulmonary baroreceptor (CPBR) sensitivity was measured using lower body negative pressure (LBNP) for 5 min at À20 mm Hg. CPBR was determined by calculating change of stroke volume and forearm vascular resistance at baseline and during LBNP. Carotid baroreceptor (CBR) sensitivity was assessed using neck suction at À20, À40, À60 and À80 mm Hg pressures, and was determined from RR interval divided by systolic blood pressure. Augmentation index (AIx), a measure of arterial stiffness, was assessed using applanation tonometry and was calculated as the ratio of augmented pressure and pulse pressure. The major findings were that the exercise group showed increase in leg vasodilation, reduction in AIx and increase in .VO 2max compared with the control group (Po0.05). However, there was no significant change for CPBR and CBR. A short-term moderate-intensity aerobic exercise intervention in young men with a family history of hypertension significantly reduced arterial stiffness and increased aerobic fitness.

“…Land-based aerobic exercise training has been shown to effectively improve AS in healthy individuals and in patients with CVD (Currie, Thomas, & Goodman, 2009;Donley et al, 2014;Moreau, Donato, Seals, DeSouza, & Tanaka, 2003;Hirofumi Tanaka, DeSouza, & Seals, 1998;Tanaka et al, 2000). Further, aquatic-based exercise training (swimming) has been shown to improve arterial compliance and blood pressure (Nualnim et al, 2012).…”

“…On the other hand, some other studies (Kingwell et al, 1997;Currie et al, 2009;Jae-Bin et al, 2013) found that whole body arterial Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/jbiomech www.JBiomech.com compliance (WBAC) and then arterial distensibility was increased after cycling and treadmill exercise with relation to the values prior to exercise. This is a different result that compares arterial distensibility before and after the period in which heart rate is increased.…”

a b s t r a c tIn this study we explore the ability of a previously developed model of pulsatile flow for explaining the observed reduction of arterial distensibility with heart rate. The parameters relevant for the analysis are arterial wall distensibility together with permeability and reflection coefficients of the end capillaries. A non-specific artery and the ensemble of tissues supplied by that artery were considered in the model. The blood current within that artery was equalized to the sum of all micro currents in the tissues supplied by that artery. A formula emerged that relates changes in arterial distensibility with heart rate, and also with some particular aspects of microcirculation. Then, that formula was tested with data of distensibilities of the radial and carotid arteries observed at the heart rates of 63, 90, and 110 b.p.m. The formula correctly predicted the trend of decreased distensibility with heart rate for both arteries. Moreover, due to the fact that the carotid artery supplies the brain, and because the Blood-Brain barrier is highly restrictive to colloids in the blood, for the carotid artery the formula predicted a less marked decrease in distensibility than in the case of the radial artery feeding muscle tissue, which has a greater permeability to colloids, a trend that was confirmed by data. It was found that reduction of arterial distensibility with heart rate was greater in arteries that supply end capillaries with high permeability and low reflection coefficients.
