| Abstract |
High-intensity heavy rope exercise (HI-HRE) improves muscular strength and increases power. To date, no studies have examined the effects of HI-HRE on arterial stiffness, carotid artery compliance or differences among these measurements between sexes. PURPOSE: To evaluate sex differences on aortic and carotid arterial stiffness (CAS), and carotid artery compliance, following an acute bout of HI-HRE. METHODS: Twenty-seven resistance-trained individuals (men: n=14, women: n=13) volunteered for the study. Aortic arterial stiffness was measured via carotid-femoral pulse wave velocity (cf-PWV). CAS, measured via beta stiffness, and carotid artery compliance, were collected via Doppler ultrasound. All measurements were collected at Rest, 15 (Rec1), 30 (Rec2), and 60 (Rec3) minutes following HI-HRE. The HI-HRE intervention consisted of six 15-second exercise bouts using a double wave pattern set at a pace of 180bpm, with 30-second seated recovery intervals between bouts. RESULTS: There were no significant sex by time interactions for cf-PWV, or beta stiffness. For carotid artery compliance there was a significant sex by time interaction (p=0.05). At Rest, women had elevated carotid artery compliance compared to men. At Rec1, women had a larger decrease in carotid artery compliance than men. Women during Rec2 experienced a significant reduction in carotid artery compliance compared to rest, whereas men increased. During Rec3, women had higher carotid artery compliance compared to men. CONCLUSIONS: These data suggest no difference in aortic or CAS between sexes following an acute bout of HI-HRE. Women had greater changes in carotid artery compliance between time points compared to men.

High-intensity heavy rope exercise (HI-HRE) is suggested to improve muscular strength and increase power. The purpose of the present study was to evaluate sex differences on aortic and carotid arterial stiffness (CAS), and carotid artery compliance, following an acute bout of HI-HRE. Twenty-seven resistance-trained individuals (men: n=14, women: n=13) participated. Aortic arterial stiffness, CAS and carotid artery compliance were measured following a HI-HRE intervention. There were no significant sex by time interactions for aortic arterial stiffness or CAS. For carotid artery compliance there was a significant sex by time interaction (p=0.05). These data suggest no difference in aortic or CAS between sexes following an acute bout of HI-HRE. Women had greater changes in carotid artery compliance between time points compared to men. |
