Effects of resistance training on arterial stiffness: a meta-analysis

Abstract

High-intensity resistance training is associated with increased arterial stiffness in young subjects with low baseline levels of arterial stiffness.

Exercise and Dietary Influences on Arterial Stiffness in Cardiometabolic Disease

“…Since exercise and dietary interventions may reduce arterial stiffness by a variety of mechanisms, additive effects 53 ; folic acid 77 Sodium restriction 58,59 ; moderate-intensity aerobic exercise training (Table S1) Aerobic exercise training [45][46][47] No evidence of benefit Vitamins (C, E) and antioxidants (α-lipoic acid) 16 Isoflavones (polyphenols) 69 Folic acid 74 ; vitamin E 80 Cocoa polyphenols 71 Folic acid 75,76 All references are to controlled trials or systematic reviews/meta-analyses. BP indicates blood pressure; CAD, coronary artery disease; DASH, Dietary Approaches to Stop Hypertension; DBP, diastolic BP; and SBP, systolic BP.…”

“…However, a recent meta-analysis of RCTs (general population) demonstrated that arterial stiffening is probably restricted to young people performing high-intensity training (ie, resistive loads >70% of the 1 repetition maximum). 53 Moderate-intensity resistance training seems to have a neutral effect on arterial properties in healthy individuals, 53 but given its possible benefits for cardiometabolic risk reduction (including BP lowering), 54 further study is warranted in cardiometabolic disease populations.…”

Effects of Resistance Training on Autonomic Nervous Function in Older Individuals

“…The authors speculated that the reason why RT did not affect HRV was that the increased arterial stiffness induced by RT might have reduced arterial baroreceptor sensitivity, resulting in a reduction in HRV. Indeed, high-intensity RT is known to be associated with worsening arterial stiffness [25]. In addition, increased arterial stiffness is inversely associated with cardiac vagal modulation [26].…”

“…The RT program included 7-10 exercises per session. The subjects carried out RT with light loads (40-60% of 1RM) and a high number of repetitions (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) with three sets during the first 7 weeks. During weeks 8-14, the loads were increased up to 60-80% of 1RM with 6-12 repetitions per set.…”

Exercise training modes and vascular adaptations

“…Moreover, another interventional study also indicated no effect of resistance training on endothelial function evaluated by endothelialdependent vasodilatation in young men 18) . Recently, metaanalysis of the association between resistance training and arterial stiffening indicated that high-intensity resistance training is associated with increased arterial stiffness in young adults with low baseline levels of arterial stiffness 19) . Furthermore, resistance training doesn't seem to be associated with IMT of the carotid artery 16,20) .…”
