Investigations into specific behaviors and practices that influence arterial stiffness has been a priority in the past few years . Chronic aerobic and anaerobic exercise activity has consistently shown to attenuate or not influence markers of arterial stiffness in adults with chronic disease and otherwise healthy adults. Chronic high functional resistance training’s effect on vascular compliance is less understood. PURPOSE: To determine the effects of a chronic high functional resistance training program on pulse wave velocity and beta-stiffness index. METHODS: Participants (18-40 years old) were placed in a non-randomized fashion into high functional resistance training (HFRT) group (n = 9; >6 months of CrossFit experience; 4 female), or control (CON) group (n = 8; < 6 months of exercise experience; 6 female). Participants in the HFRT group trained at the same local facility 4 -5 days a week, utilizing the same training program. CON group refrained from exercise during the study period. Body composition, 1,000 meter rowing test, deadlift 1 repetition maximum (1 RM), hemodynamic assessments and vascular compliance was assessed at baseline and follow-up. Repeated measures analysis of variance was used to examine within and between interactions on indices of arterial stiffness. RESULTS: There were baseline differences between groups in deadlift 1 RM (72.3 ± 18.2 kg mean difference (MD), p < 0.01), rowing time (143.8 ± 35.7 sec MD, p < 0.01), and rowing average watts (153.8 ± 34.6 watts MD, p < 0.01). Following the intervention, seated diastolic blood pressure (DBP) increased only in the CON group (3 ± 4 mmHg MD, p = 0.04). No significant differences within and between group interactions were found in arterial stiffness variables. CONCLUSIONS: The findings indicate indices of arterial stiffness are not influenced by participation in chronic high functional resistance training.Copyright © 2023 by the American College of Sports MedicineView full article text
