Background/Purpose: Resistance exercise (RE) is known to improve cardiovascular health, but the role of RE variables on arterial stiffness is inconclusive. In this systematic review and meta-analysis, we investigated the influence of RE and its intensities on arterial stiffness measured as pulse wave velocity (PWV) in young and middle-aged adults.Methods: Web of Science, PubMed/MEDLINE, Scopus, EMBASE, Cochrane Library, ScienceDirect, CINAHL, Wiley Online Library, and Google Scholar were searched for relevant studies. RE trials that reported PWV data, and compared with respective controls were included. The Cochrane Collaboration tool was used to assess the risk of bias.Results: Data were synthesized from a total of 20 studies, involving 981 participants from control (n = 462) and exercise (n = 519) trials. The test for overall effect (pooled outcome) showed RE intervention had no effect on arterial stiffness (SMD = −0.09; 95% CI: −0.32, 0.13; P = 0.42), but risk of heterogeneity (I2) was 64%. Meta-regression results revealed a significant correlation (P = 0.042) between RE intensity and PWV changes. Consequently, the trials were subgrouped into high-intensity and low-to-moderate-intensity to identify the effective RE intensity. Subgroup analysis showed that low-to-moderate-intensity significantly decreased PWV (SMD = −0.34; 95% CI: −0.51, −0.17; P < 0.0001), while high-intensity had no effect (SMD = 0.24; 95% CI: −0.18, 0.67; P = 0.26). When trials separated into young and middle-aged, low-to-moderate-intensity notably decreased PWV in young (SMD = −0.41; 95% CI: −0.77, −0.04; P = 0.03) and middle-aged adults (SMD = −0.32; 95% CI: −0.51, −0.14; P = 0.0007), whereas high-intensity had no effect in both age groups.Conclusions: Our findings demonstrated that RE intensity is the key variable in improving arterial stiffness. Low-to-moderate-intensity can prescribe as an effective non-pharmacological strategy to treat cardiovascular complications in young and middle-aged adults.

Impedance modulus in the range of first harmonic oscillations (0.78–1.56 Hz), which reflects heart rate at rest, was lower in middle-aged endurance athletes than in age-matched sedentary peers and was similar to young individuals. Prolonged endurance training is associated with the improved cerebrovascular dampening function in middle-aged adults. Lower cerebrovascular impedance modulus may contribute to maintaining brain perfusion in midlife.

Background and objectives: Several anthropometric and body composition parameters have been linked to arterial stiffness (AS) as a biomarker of cardiovascular disease. However, little is known about which of these closely related factors is more strongly associated with AS. The aim of the present study was to analyze the relationship of different anthropometric and body composition parameters with AS in middle-aged adults. Materials and Methods: This cross-sectional study included 186 middle-aged participants (85 women, 101 men; age = 42.8 ± 12.6 years) evaluated as part of the Healthy UAL study, a population study conducted at the University of Almería with the main purpose of analyzing the etiology and risk factors associated with cardio-metabolic diseases. Anthropometric measures included neck, waist, and hip circumferences, as well as the waist-to-height ratio (WHtr). Bioimpedance-derived parameters included fat-free mass index (FFMI), fat mass index (FMI), and percent of body fat (%BF). AS was measured by pulse wave velocity (PWV). The relationships of interest were examined through stepwise regression analyses in which age and sex were also introduced as potential confounders. Results: Neck circumference (in the anthropometric model; R 2: 0.889; β: age = 0.855, neck = 0.204) and FFMI (in the bio-impedance model; R2: 0.891; β: age = 0.906, FFMI = 0.199) emerged as significant cross-sectional predictors of AS. When all parameters were included together (both anthropometry and bio-impedance), both neck circumference and FFMI appeared again as being significantly associated with AS (R2: 0.894; β: age = 0.882, FFMI = 0.126, neck = 0.093). Conclusion: It was concluded that FFMI and neck circumference are correlated with AS regardless of potential confounders and other anthropometric and bioimpedance-derived parameters in middle-aged adults.

Background: Arterial stiffness (AS) indicates the initial stage of cardiovascular disease (CVD), which associated with modifiable and lifestyle risk factors. We aimed to examine the association of AS with anthropometric indices, lipid profiles, and physical activity. Methods: 658 healthy middle-aged adults selected and anthropometric indices (body mass index (BMI), waist circumferences (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), neck circumferences (NC), a body shape index (ABSI), body roundness index (BRI), body-fat mass (BFM), visceral-fat, fat-free mass(FFM), lipid profiles, and PA were measured. Arterial Stiffness measured by carotid-femoral pulse wave velocity (cf-PWV) and central augmentation index (cAIx). Results: Our results show, cf-PWV positively associated with TGs (β = 0.10, p = 0.01) and in anthropometric indices corelated with, WC (β = 0.11, p = 0.02), WHR (β = 0.09, p = 0.03), WHtR (β = 0.1, p = 0.02), and BRI (β = 0.09, p = 0.04). cAIx was independently positive association with cholesterol (β = 0.08, p = 0.03), WC (β = 0.1, p = 0.03), WHR (β = 0.09, p = 0.02), ABSI (β = 0.09, p = 0.01), BRI (β = 0.08, p = 0.05), visceral-fat area (β = 0.09, p = 0.03) and BFM (β = 0.08, p = 0.04) and negatively associated with PA (β = -0.08, p = 0.03). Conclusions: WC, WHR, and BRI were associated with both cf-PWV and cAIx. TGs and WHtR associated with cf-PWV, while cAIx was associated with ABSI, so improving these indices may be helpful to prevent CVD.

С возрастом частота сердечно-сосудистых заболеваний неуклонно растет во всем мире. Проживание человека в суровых климатогеографических условиях Арктики сопряжено с преждевременным старением, более ранним и частым развитием возраст-ассоциированных болезней. По-всей видимости, эти процессы обусловлены функциональными изменениями крупных сосудов, состояние которых до настоящего времени не изучено. Цель и методы исследования - выявить корреляцию показателей старения с параметрами центральной гемодинамики и жесткости артерий, измеренными с помощью аппланационной тонометрии на аппарате «Сфигмокор», у мужчин среднего возраста, живущих на Европейском Севере России. Впервые отмечены положительные связи параметров периферического и центрального кровяного давления, аугментационного давления и аугментационного индекса и отрицательная корреляция времени возврата отраженной волны и амплификации пульсового давления с показателями старения, что указывает на возрастное снижение эластичности артерий. Также обнаружена отрицательная связь показателя субэндокардиальной жизнеспособности миокарда с северным стажем и биологическим возрастом мужчин. Результаты исследования имеют теоретическую значимость: они продемонстрировали потенциальное участие сосудов в патогенезе преждевременного старения и развития сердечнососудистых заболеваний. Практическая ценность работы связана с необходимостью разработки профилактических мер, направленных на контроль давления, снижение жесткости артерий и кардиоваскулярного риска у северян среднего возраста. With age, the incidence of cardiovascular diseases is steadily increasing worldwide. Living in the harsh climatic and geographical conditions of the Arctic is associated with premature aging, earlier and more frequent development of age-associated diseases. Apparently, these processes are caused by functional changes in large vessels, the state of which has not yet been studied. Aim and methods: to identify correlations of aging and biological age indicators with the parameters of central hemodynamics and arterial stiffness measured using applanation tonometry by the «Sphygmocor» device in middle-aged men living in the European North of Russia. For the first time, positive associations of parameters of peripheral and central blood pressure, augmentation index, and negative correlation of the time of return of the reflected wave and pulse pressure amplification with indicators of aging were noted, which indicates an age-related decrease in arterial elasticity. There was also a negative association of the subendocardial viability ratio with the northern experience and biological age. Theoretically considered, the results demonstrate the potential involvement of blood vessels in the pathogenesis of premature aging. The practical significance of the work is related to the need to develop preventive measures aimed at controlling blood pressure, reducing arterial stiffness and cardiovascular risk in middle-aged northerners.

Maximum concentric (CONC) and eccentric (ECC) strength of the ankle plantar flexor muscles were compared between middle-aged adults who regularly participated in resistance exercise training versus those who participated in weight-bearing endurance exercise. A total of 40 men and women with a mean age of 48.9 years (SD = 5.3) were tested for CONC and ECC plantar flexor (PF) strength, using an isokinetic device at 3 velocities: 30, 90 and 180°/s. Mean strength values for the groups of men and women involved in resistance exercise were consistently higher than those involved in the endurance training for the CONC tests, where values ranged from 35% to 46% (avg. 41%, p < .01), but less between-group difference was observed for the ECC loading condition: 4% to 30% (avg. 18%). Thus ECC/CONC ratios, which rose with increasing velocity, were consistently higher for the endurance group vs. resistance-trained. Finally, since concentric PF torque values were found to be quite low for the middle-aged women who did only endurance training, this movement may require preventive strengthening exercises.
