Book excerpt: ABSTRACT: The study was designed to examine the effects of one bout of acute moderate resistance exercise on arterial stiffness in postmenopausal women. Nine untrained postmenopausal women [age 59.79 ± 6.22, weight 73.89 ± 13.08 kg, height 162.89 ± 6.11 cm, BF% 36.33 ± 8.85%] who had refrained from food and caffeine 4 hr prior to the intervention session and the control session, as well as avoided vigorous exercise 24 hr prior to the intervention session and control session, performed one bout of moderate intensity resistance exercise (70% of 10-RM). The exercises performed involved both the upper body and the lower body; dumbbell (DB) bent-over row, DB chest press, DB bicep curl, DB tricep extension, DB squats, DB Romanian deadlifts (RDLs), DB lunges, and DB calf raises. Measurements of heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), central systolic blood pressure (CSBP), central diastolic blood pressure (CDBP), pulse wave velocity (PWV), and augmentation index (AIx) were taken at baseline after 10 min of supine rest, post exercise, 30 min post exercise, and 60 min post exercise. Heart rate, SBP, CSBP, and CDBP were significantly (p .05) affected by resistance training immediately post-exercise. Pulse wave velocity and AIx were not significantly (p .05) affected by the exercise session. One reason why PWV and AIx, prime measures of arterial stiffness, were not significantly altered may have been the subjects' low exercise intensity. In conclusion, no effects of the exercise were observed in PWV or AIx. However, moderate intensity resistance exercise resulted in post-exercise hypotension in postmenopausal women which may be valuable information for future research.

This book was released on 2021 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Elevated arterial stiffness has been recognized as an independent risk factor for cardiovascular disease and has been associated with long-term worse clinical outcomes in several populations. The purpose of this study was to investigate the effects of gender and time following one acute bout of moderate intensity resistance exercise on arterial stiffness in college-aged men and women. A total of 26 men (n = 14) and women (n = 12) completed three sessions: screening, familiarization, and testing in the order they are listed. There were no changes in pulse wave velocity or augmentation index in either men or women across time. Men did have significantly higher systolic blood pressure at baseline (p = .00, d =1.4), immediately post exercise (p = .01, d = 1.0) and 30 minutes post exercise (p = .04, d = .08) relative to women. Men also had significantly higher heart rates immediately post exercise (p = .02, d = 0.9) and 30 minutes post exercise (p = .04, p = 0.9) when compared to women. The lack of change in parameters of arterial stiffness suggest moderate intensity exercise does not increase arterial stiffness in college-aged adults.

Book excerpt: Abstract: The investigation was designed to determine the effect of moderate and high intensity resistance exercise (RE) on arterial stiffness (AS) . Subjects consisted of young healthy males who regularly resistance trained (N = 12) Each subject completed both the moderate and high intensity bouts in a randomized order. Pulse wave velocity (PWV) was used to estimate AS and was measured at baseline, 10 mm post, 20 mm post, and 30 mm post. Heart rate (HR) was measured during each bout to serve as a marker of sympathetic nervous system activity. A total body RE workout was completed during each bout and consisted of four free weight exercises. Significant increases (p

This book was released on 2016 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: High-Intensity Interval Training (HUT) has been associated with greater reductions in cardiovascular disease (CVD) risk factors when compared to continuous moderate exercise. Arterial stiffness (AS) is an independent risk factor for CVD that increases exponentially in women following menopause. The current research was designed to investigate the acute AS response to a single bout of HUT versus a single bout of moderate continuous endurance training (MCT) in postmenopausal women. A total of 13 women (age = 60.85 +/- 4.41 years) completed the study. Subjects completed both a HUT and a MCT exercise protocol on separate occasions. Pulse wave velocity (PWV), augmentation index (AIx), central systolic blood pressure (CSBP), and central diastolic blood pressure (CDBP) were measured preexercise, 15 min postexercise, and 30 min postexercise to assess arterial stiffness. No significant interaction (p > .05) between exercise intervention and time was determined for PWV, AIx, CSBP, or CDBP. A trend was found for a greater decrease in AIx following HUT compared to the decrease in AIx following MCT (p = .086) . A significant (p

Book excerpt: Arterial stiffness increases cardiovascular disease risk for stroke, myocardial infarction, and mortality. The aim of this study was to examine the influence of resistance exercise intensity on arterial stiffness and blood pressure. Two resistance exercise conditions, low and high intensity, were compared. In a longitudinal, cross-over study design, thirty-two subjects (n=32, 17 male, mean age= 24.6) completed both conditions on separate days. Pulse wave velocity (PWV) was used as a measure of central and peripheral arterial stiffness at baseline, at 15 minutes post, and at 30 minutes post exercise. Central PWV increased in the low mode and returned toward baseline at 30 minutes post-exercise (p

This book was released on 2016 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The study was designed to determine the effect of moderate intensity resistance exercise on arterial stiffness with and without the Valsalva maneuver. Subjects {N = 13) consisted of males between 18-30 years old who were familiar with resistance training. All subjects completed one session of moderate intensity resistance exercise (60% of 1-RM) with the Valsalva maneuver, and a second session without the Valsalva maneuver in a counterbalanced order. Pulse wave velocity (PWV) was used to measure arterial stiffness before exercise, 10 min post, 30 min post, and 60 min postexercise. No significant interaction F(3,36) = 0.74, p = .54 was found between the condition of Valsalva maneuver, or no Valsalva maneuver, and the test occasion. No significant main effect F(l,12) = 0.02, p = .89 was found for the treatment condition of Valsalva maneuver and no Valsalva maneuver. Also, no significant main effect F(1.96, 23.57) = 0.18, p = .84 was found for test occasion (preexercise, 10 min post, 30 min post, and 60 min postexercise). Moderate intensity resistance exercise with and without the Valsalva maneuver did not negatively affect arterial stiffness.

This book was released on 2018 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical activity is a powerful behavioral intervention that can improve key metabolic and cardiovascular risk factors in aging women. Although a considerable amount of research has focused on the health benefits of aerobic exercise participation among aging women, much less is known about physiological and affective responses to an acute bouts of resistance exercise in women who are postmenopausal. The purpose of this study was to determine the effects of RE intensity on physiological, affective, and motivational outcomes in postmenopausal women at heightened risk for chronic disease. A total of 13 overweight women who were postmenopausal (Age: 9.23±11.31 years; Height: 63.27±2.74in: Weight: 77.23±10.60kg) participated in the study. Each participant completed 3 experimental conditions. Prior to experimental conditions, participants completed a baseline assessment of strength and body composition, 6 familiarization sessions to acclimate participants to the resistance exercises and loads for each condition. Three sets of each exercise were performed in each experimental, whereas the load and number of repetitions lifted differed in each experimental condition. The low-load condition involved sets of 12-15 reps at 55%-64% 1 repetition maximum (RM), with 60 seconds of rest between sets. The moderate load involved sets of 8-12 reps at 65%-75% 1RM, with 90 seconds of rest between sets. The heavy load involved sets of 3-6 reps at 80-90% 1RM, with 120 seconds of rest between sets. Assessment of inflammatory markers were obtained prior to, immediately after, 15 minutes and 30 minutes after each experimental condition. The feeling scale (FS) was administered before, during (after the third set of each exercise) and immediately following each condition. Rate of perceived exertion (RPE) was assessed following each set. Motivation was assessed before and immediately following each session. Self-Efficacy and intention were assessed immediately following each session. Results revealed no significant time, condition or time x condition differences in cortisol, inflammatory markers or motivational correlates. There was a significant time effect for lactate, with levels peaking immediately after each experimental condition before returning to baseline before 30 minutes after exercise. There was no difference in intention or self-efficacy between experimental conditions. It is concluded that acute bouts of RE at 55-64% 1RM, 65-75% 1RM and 80-90% 1RM result in comparable metabolic stress, inflammatory and affective responses. This lends further support to the safety and tolerability of high load resistance exercise in postmenopausal women. Given the comparable, positive affective response after the low, medium and high conditions in our study, fitness professionals could capitalize on these findings by encouraging postmenopausal women to select higher loads that may confer specific strength benefits, yet still yield positive affective responses.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Contracting skeletal muscle is capable of producing a metabolic response involving the production of large amounts of intracellular messengers known as cytokines. IL-6 is one cytokine known to be released in response to muscular contraction. Plasma IL-6 concentrations have been shown to increase significantly followed intense resistive exercise, and muscle-derived IL-6 is capable of reducing the inflammatory response of blood mononuclear cells. Purpose: To examine the effects of an acute bout of resistive exercise on inflammatory markers in the blood, 23 obese, postmenopausal women performed a high intensity resistive exercise session and the effects of contraction-induced IL-6 on LPS-stimulated TNF-Æá and IL-1Æâ production were measured. Methods: Obese, postmenopausal (65.65 ¡l 3.89 years) women (N=23) were acclimated to resistive exercise over a three day period. After the acclimation period, participants were randomized into one of two groups: non-exercising control group (CON; N=11) or exercise group (EX; N=12). At least three days after the third acclimation day, participants reported to the lab and either completed a resistive exercise session (EX) at 80% of their estimated 1-RM, or rested quietly in the lab (CON). Blood samples were obtained pre, post, 2 hours-post, and 24 hours-post exercise. Similar time points were used in the CON group. Blood samples were analyzed using ELISA for plasma IL-6 concentrations. Whole blood samples were stimulated with LPS endotoxin and incubated for 24 hours in physiological conditions (37·ƠC, 5% CO2). LPS-stimulated production of TNF-Æá and IL-1Æâ were measured in the stimulated supernatants to assess immunocreativity of blood mononuclear cells. Results: Plasma IL-6 increased significantly following the exercise session (p

Available in PDF, EPUB and Kindle. Book excerpt: Endothelial dysfunction, or the inability of an artery to dilate sufficiently when subjected to excessive shear stress, serves both as a predictor of future cardiovascular events as well as an early indication of atherosclerosis. Several chronic disease states, including obesity, have been shown to alter endothelial function, which may be mediated through circulating pro- and anti-inflammatory adipokines. Still, the mechanisms by which obesity-related low-grade inflammation alters endothelial function are not fully elucidated. Acute and chronic endurance exercise training has previously been shown to be effective in improving endothelial function; however, chronic resistance exercise training is not universally regarded as beneficial to vascular functioning. Far fewer studies have examined the effect of acute resistance exercise on vascular function and adipokine release. To further understand the effects of resistance exercise training on vascular function, a meta-analysis was completed to examine the effects of resistance training on brachial artery flow mediated dilation (FMD), a common measure of endothelial function. The results of the meta-analysis indicate that resistance training has a small positive effect on FMD. Additionally, the effects of an acute bout of lower body resistance exercise on forearm blood flow (FBF) and two inflammatory cytokines were evaluated in obese (>30% body fat) and non-obese ([less or equal to] 30% body fat) subjects. It was hypothesized that the resistance exercise bout would increase FBF, that those changes would be greater in obese versus non-obese subjects, and that the changes in circulating cytokines (adiponectin and tumor necrosis factor-[alpha]) would be related to changes in FBF. The results indicate that FBF measures in obese and non-obese subjects react in a divergent pattern immediately following resistance exercise but return to baseline within 24 hours. These changes were not related to changes in adiponectin or TNF-[alpha] although changes in adiponectin were related to changes in TNF-[alpha]. In conclusion, resistance exercise training programs may have a small positive effect on vascular function which may reduce overall cardiovascular disease risk. Additionally, obese and non-obese subjects display differing patterns of vascular responses to an acute bout of resistance exercise, supporting the view that obesity, and its associated low-grade inflammatory response, may negatively alter vascular homeostasis.
Download or read book The Effects of Bilateral and Unilateral Upper body Acute Resistance Exercise on Cardiovascular Function written by Erica M. Marshall and published by . This book was released on 2020 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the present study was to determine if unilateral upper-body acute RE [resistance exercise] would attenuate alterations in measures of cardiovascular function compared to bilateral upper-body acute RE. Twenty moderately active individuals completed upper-body maximal strength testing followed by two acute RE sessions. Measures of hemodynamics, autonomic modulation, central arterial stiffness, pulse wave reflection, and baroreflex sensitivity were measured at Rest and at 10- and 30-minutes during recovery. Interestingly, there were no significant condition by time interactions for any variable. Still, measures of hemodynamics, autonomic modulation, central arterial stiffness, pulse wave reflection and baroreflex sensitivity were significantly altered from Rest during recovery from upper-body acute RE. Specifically, the hemodynamic measure heart rate was augmented for at least 30 minutes. These changes were accompanied by alterations in measures of autonomic modulation specific to vagal activity, which were predominantly attenuated for at least 30 minutes. Further, central arterial stiffness was increased and measures of pulse wave reflection in terms of the pulse waveform were also augmented for at least 10 and 30 minutes, respectively. Other pulse wave reflection measures indicative of left ventricular function suggested an increase in myocardial workload and decrease in coronary blood flow for at least 30 minutes. Further, baroreflex sensitivity was reduced for at least 30 minutes. Collectively, this study suggests that unilateral upper-body acute RE does not seem to be an appropriate upper-body acute RE modality to reduce cardiovascular modulation compared to bilateral RE. Nevertheless, both modalities significantly altered cardiovascular function.
