So while it's controversial among researchers, there are loads of articles that show a single bout of exercise to increase arterial stiffness. Arterial stiffness, as measured by pulse wave variability (PWV), is associated with the risk of cardiovascular disease and stroke.
None of this is new or innovative, just giving a background.
I just began researching this as a small assignment I have to do for a class, and so far have not been able to find definitive conclusions for whether long term high intensity weight training has a negative impact on cardiovascular function. Either way, it would only seem logical to want to reduce this effect if at all possible when destroying are bodies in the gym on a daily basis right?
So to the contrary of resistance training, there is a ton of info discussing the positive effects of aerobic exercise on arterial stiffness and reduced PWV
This article discusses how performing cardio for 30 min after resistance training was enough to attenuate the arterial stiffening effect from weight training. However, when cardio was performed before RT there was no change.

Combined aerobic and resistance training and vascular function: effect of

Aerobic exercise training combined with resistance training (RT)
might prevent the deterioration of vascular function. However, how
aerobic exercise performed before or after a bout of RT affects
vascular function is unknown. The present study investigates the
effect of aerobic exercise before and after RT on vascular function.
Thirty-three young, healthy subjects were randomly assigned to
groups that ran before RT (BRT: 4 male, 7 female), ran after RT
(ART: 4 male, 7 female), or remained sedentary (SED: 3 male, 8
female). The BRT and ART groups performed RT at 80% of one
repetition maximum and ran at 60% of the targeted heart rate twice
each week for 8 wk. Both brachial-ankle pulse wave velocity
(baPWV) and flow-mediated dilation (FMD) after combined training
in the BRT group did not change from baseline. In contrast, baPWV
after combined training in the ART group reduced from baseline
(from 1,025 43 to 910 33 cm/s, P 0.01). Moreover, brachial
artery FMD after combined training in the ART group increased from
baseline (from 7.3 0.8 to 9.6 0.8%, P 0.01). Brachial artery
diameter, mean blood velocity, and blood flow in the BRT and ART
groups after combined training increased from baseline (P 0.05,
P 0.01, and P 0.001, respectively). These values returned to the
baseline during the detraining period. These values did not change in
the SED group. These results suggest that although vascular function
is not improved by aerobic exercise before RT, performing aerobic
exercise thereafter can prevent the deteriorating of vascular function.
This article is brand new and I haven't been able to access the full version yet, but is interesting as well. It claims that supplementing with creatine also may attenuate the negative impact of resistance training on arterial compliance.
Abstract
Arterial stiffness and hemodynamics may be increased following a bout of resistance exercise. Oral creatine supplementation (Cr) may attenuate cardiovascular responses after exercise via improved anaerobic metabolism. This study was aimed to determine the effect of Cr on hemodynamic and arterial stiffness responses after acute isokinetic exercise. Sixteen healthy males (22.6 ± 0.6 year) were randomly assigned to either placebo (Pl, n = 8) or Cr (n = 8) (2 × 5 g/day) for 3 weeks. Brachial systolic blood pressure (SBP), heart rate (HR), brachial-ankle pulse wave velocity (baPWV), and leg PWV were measured in the supine position at rest before and after the interventions. After the supplementation period, parameters were also measured 5 min (PE5) and 15 min (PE15) after two sets of leg isokinetic exercise. There was no difference between the groups in resting measurements before and after the supplementation. Compared with the Pl group, the Cr group had attenuated (P < 0.05) increases in SBP at PE5 (Pl 14.0 ± 2.5, Cr 5.6 ± 2.3 mmHg), HR at both P5 (Pl 28 ± 4 vs. Cr 16 ± 2 beats/min) and PE15 (Pl 21 ± 3, Cr 11 ± 2 beats/min) and rate pressure product at P5 (Pl 45.8 ± 6.4, Cr 24.8 ± 2.2) and P15 (Pl 34.2 ± 5.0, Cr 15.9 ± 6.0). Compared with the Pl group, the Cr group had suppressed increases in baPWV at PE5 (Pl 1.5 ± 0.4, Cr −0.1 ± 0.4 m/s) and PE15 (Pl 1.1 ± 0.2, Cr −0.3 ± 0.3 m/s) and returned SBP to pre-exercise values at PE15 (Pl 10.6 ± 2.8, Cr 2.1 ± 2.6 mmHg). PWV in the exercised leg decreased at PE5 in both groups. These findings suggest that Cr supplementation attenuates the hemodynamic and baPWV responses after acute isokinetic exercise.
