Ítem Heart Rate from Progressive Volitional Cycling Test Is Associated with Endothelial Dysfunction Outcomes in Hypertensive Chilean Adults(2023-03) Alvarez, Cristian; Tuesta, Marcelo; Reyes, Álvaro; Guede-Rojas, Francisco; Peñailillo, Luis; Cigarroa, Igor; Vásquez-Gómez, Jaime; Cano-Montoya, Johnattan; Durán-Marín, Cristóbal; Rojas-Paz, Oscar; Márquez, Héctor; Izquierdo, Mikel; Delgado-Floody, PedroBackground: A progressive volitional cycling test is useful in determining exercise prescription in populations with cardiovascular and metabolic diseases. However, little is known about the association between heart rate during this test and endothelial dysfunction (EDys) parameters in hypertensive (HTN) patients. Objective: To investigate the association between EDys markers (flow-mediated dilation [FMD], pulse wave velocity of the brachial artery [PWVba], and carotid-intima media thickness [cIMT]) and heart rate during a cycling test in HTN adults. A secondary aim was to characterize cardiovascular, anthropometric, and body composition outcomes in this population. Methods: This was a descriptive clinical study in which adults (men and women) were assigned to one of three groups: HTN, elevated blood pressure (Ele), or a normotensive control group (CG), and completed a progressive cycling test. The primary outcomes were FMD, PWVba, cIMT, and heart rate (HR) at 25–50 watts (HR25–50), 50–100 watts (HR50–100), and 75–150 watts (HR75–150) of the Astrand test. Secondary outcomes included body mass index (BMI), waist circumference, body fat percentage (BF%), skeletal muscle mass (SMM), resting metabolic rate (RMR), and estimated body age, as measured by a bio-impedance digital scale. Results: Analyses of the associations between FMD, PWV, and HR25–50, HR50–100, and HR75–150 watts revealed no significant association in the HTN, Ele, and CG groups. However, a significant association was found between cIMT and HR75–150 watts in the HTN group (R2 47.1, β −0.650, p = 0.038). There was also a significant trend (p = 0.047) towards increasing PWVba in the CG, Ele, and HTN groups. Conclusion: Heart rate during a progressive cycling test is associated with the EDys parameters cIMT in HTN patients, with particularly strong predictive capacity for vascular parameters in the second and third stages of the Astrand exercise test compared to normotensive control. © 2023 by the authors.Ítem Hypertensive patients show higher heart rate response during incremental exercise and elevated arterial age estimation than normotensive adult peers: VASCU-HEALTH PROJECT(Federación Española de Docentes de Educación Física, 2023) Alvarez, Cristian; Campos-Jara, Christian; Gomes Ciolac, Emmanuel; Vega Guimaraes, Guilherme; Andrade-Mayorga, Omar; Cano-Montoya, Johnattan; Andrade, David C.; Delgado-Floody, Pedro; Alonso-Martínez, Alicia; Izquierdo, Mikel; Cigarroa, IgorThere is limited information regarding heart rate (HR) response from predictive formulae and actual exercise tests between arterial hypertension (HTN) and normotensive adults, as well as about vascular similarities or differences between samples of different blood pressure control. This study aimed 1) to describe and compare the HR during exercise between HTN and normotensive adults and 2) to describe the endothelial function and related vascular parameters in both groups. A descriptive clinical study was conducted with 64 adults (men and women) who were divided into three groups: arterial hypertension (HTN n=26), elevated blood pressure (Ele n=16), or normotensive control (CG n=22). The participants underwent an incremental cycling exercise test of 5 stages, where HR (primary outcome) was measured, and secondary vascular outcomes (percentile classification of the pulse wave velocity (%ILEPWVba), maximum carotid intima-media thickness (cIMTmax), and arterial age among others were measured. In stage 2 of the test (50-100 watts), the HTN group showed significantly higher HR vs. CG (+14 beats/min; p<0.05) and vs. Ele group (+15 beats/min; p<0.05), and in stage 5 (125-250 watts), HTN group showed higher HR vs. CG (+22 beats/min; p<0.05). HTN group showed a higher arterial stiffness by %ILEPWVba classification and arterial age estimation than the CG group. In conclusion, HTN patients reported a higher HR response only in two out of five (monitored) stages of the Astrand cycling exercise test than normotensive peers. Moreover, all groups showed a higher HRpredicted than real HRpeak obtained from the exercise test. These results are displayed with more altered vascular parameters in the HTN group. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF)Ítem Similar adaptations to 10 weeks concurrent training on metabolic markers and physical performance in young, adult, and older adult women(MDPI, 2021-12) Andrade, David C.; Flores-Opazo, Marcelo; Peñailillo, Luis; Delgado-Floody, Pedro; Cano-Montoya, Johnattan; Vásquez-Gómez, Jaime A.; Alvarez, CristianIt has been proposed that the combination of high-intensity aerobic exercises and resistance training (RT) known as concurrent training (CT) could improve metabolic syndrome (MetS) markers, and that the exercise mixture in CT could dampen muscle anaerobic pathways, a result known as the interference effect. However, there is scarce evidence on its effects in women across different ages. Therefore, we sought to determine the effects of a 10-week CT intervention on MetS markers and endurance performance in adult women and compared age-related differences between young, adult, and older participants. A total of 112 women with >1 MetS risk factors were included in the study. Participants were allocated to different groups according to the following cutoff age ranges: 20–29years (y), n = 25; 30–39y, n = 35; 40–49y, n = 43; and 50–59y, n = 53. Participants performed 10 weeks of CT, including resistance training (RT), involving six major muscle groups, and high-intensity interval training (HIIT) in a cycle ergometer. Anthropometric, cardiovascular, metabolic, and performance outcomes were assessed before and after the intervention. The CT induced significant improvements in waist circumference (WC) (20–29y: –2.5; 30–39y: –4.1; 40–49y: –4.2; 50–59y: –2.8 ∆cm) and the distance achieved in the six-minute walking test (6Mwt) (20–29y: +47.6; 30–39y: +66.0; 40–49y: +43.0; 50–59y: +58.6 ∆m) across all age groups, without significant differences between groups. In addition, a significant correlation was found between 6Mwt and WC, independent of age. In conclusion, our results showed that a 10-week CT intervention improved MetS risk factors in women, suggesting that the beneficial effects promoted by CT are independent of age and confirming CT as an effective, age-independent training regimen to improve metabolic health in women. © 2021 by the authors.
