“…A carotid arterial waveform has been used as the central arterial waveform to esti- mate SAC non-invasively (10). In the present study, a finger arterial waveform was transformed to a brachial arterial waveform using analysis software (Beatscope; TNO-BMI, Amsterdam, the Netherlands) (20,21); the transformed arterial waveform was used to calculate SAC instead of the carotid arterial waveform (22,23). We estimated SV using the Modelflow method from the transformed arterial waveform using Beatscope (24,25).…”

“…The impairment of such a function (e.g., arterial stiffening) results in a greater reflected wave from the periphery, which induces excessive elevations of LV afterload causing extra myocardium work. Previous studies have reported that higher physical conditioning status, indexed by maximal and sub-maximal aerobic capacity, is associated with reduced arterial stiffness, and vice versa [3,4]. Therefore, arterial stiffening might be unfavorable for aerobic performance because of excessive myocardium work.…”

Lack of elasticity in the central artery causes an increase in left ventricular (LV) afterload. Although regular moderate-intensity endurance exercise improves cardiovascular function, including arterial destiffening, little is known about the effect of short-term vigorous exercise on cardiovascular function (i.e., the interaction between cardiac and arterial functions). We measured arterial stiffness [via pulse wave velocity from the heart to ankle (haPWV)] and LV contractility (via systolic interval time) before and after a 1-week training camp in a total of 33 regularly highly-trained collegiate endurance runners. They participated in three training sessions per day which mainly consisted of long-distance running and sprint training. The averaged running distance was ≈ 44% longer during the camp than the regular training program. After the camp, heart rate at rest and haPWV were significantly increased, whereas blood pressure remained unchanged. Although a ratio of pre-ejection period and LV ejection time (PEP/LVET, an index of blunted LV contractility) was unaltered, presumably due to the large variability of individual response, there was a significant correlation between changes in haPWV and PEP/LVET (r = 0.54, P < 0.01). These results suggest that, in regularly highly-trained endurance athletes, arterial stiffness increases after a training camp characterized by greater training volume (vs. regular training), and that the individual response in arterial stiffness correlates with the corresponding changes in myocardial contractility.

“…The increase in preload would ensure a greater reliance on the Frank-Starling mechanism and may account for the increase in SV found at 40 W [33]. Furthermore, reductions in SBP at 40 W could have reduced afterload and aided in the increase in SV [28]. Perini et al [34] suggested that lower arterial pressures at low and medium exercise intensities could reflect a lower level of activation of the sympathetic system elicited by the same absolute load after training.…”

“…The reduction in RPP may be the result of improved systemic arterial compliance (reduced SBP) during the submaximum cycle ergometry test. This is of particular importance as systemic arterial compliance has been shown to be a major contributor to increased myocardial oxygen consumption during submaximum aerobic exercise [28]. The lower HR at 40 W and 50% of VO 2max may be because of a lower level of sympathetic activity.…”
