The purpose of the present study was to determine if unilateral upper-body acute RE would attenuate alterations in measures of cardiovascular function compared to bilateral upper-body acute RE. Twenty moderately active individuals completed upper-body maximal strength testing followed by two acute RE sessions. Measures of hemodynamics, autonomic modulation, central arterial stiffness, pulse wave reflection, and baroreflex sensitivity were measured at Rest and at 10- and 30-minutes during recovery. Interestingly, there were no significant condition by time interactions for any variable. Still, measures of hemodynamics, autonomic modulation, central arterial stiffness, pulse wave reflection and baroreflex sensitivity were significantly altered from Rest during recovery from upper-body acute RE. Specifically, the hemodynamic measure heart rate was augmented for at least 30 minutes. These changes were accompanied by alterations in measures of autonomic modulation specific to vagal activity, which were predominantly attenuated for at least 30 minutes. Further, central arterial stiffness was increased and measures of pulse wave reflection in terms of the pulse waveform were also augmented for at least 10 and 30 minutes, respectively. Other pulse wave reflection measures indicative of left ventricular function suggested an increase in myocardial workload and decrease in coronary blood flow for at least 30 minutes. Further, baroreflex sensitivity was reduced for at least 30 minutes. Collectively, this study suggests that unilateral upper-body acute RE does not seem to be an appropriate upper-body acute RE modality to reduce cardiovascular modulation compared to bilateral RE. Nevertheless, both modalities significantly altered cardiovascular function.
