Available in PDF, EPUB and Kindle. Book excerpt: As the first primer on the effects of exercise on human hypertension, Effects of Exercise on Hypertension: From Cells to Physiological Systems provides the state-of-the-art effects of exercise on the many possible mechanisms underlying essential hypertension in humans. The book contains chapters by distinguished experts on the effects of exercise on physiological systems known to be involved in hypertension development and maintenance as well as less well known aspects of hypertension such as 24-hour ambulatory blood pressure profile and oxidative stress. An emerging area, the effects of resistance exercise training on blood pressure is also covered. A unique aspect of the book is that it covers the effects of exercise mimetics on vascular cell adaptations in order to begin to elucidate some of the cellular mechanisms that may underlie blood pressure reductions with exercise training. Lastly, the book will end with a chapter on the interactive effects of genes and exercise on blood pressure. Chapters are grouped by physiological system or mechanism. The text begins with two overview chapters; one on the general effects of aerobic exercise training and the second on the general effects of resistance exercise training on blood pressure. Each chapter begins with a bulleted list of key points. Effects of Exercise on Hypertension: From Cells to Physiological Systems will be of great value to professional individuals in cardiovascular medicine, the cardiovascular sciences, allied health care professionals, and medical and graduate students in the cardiovascular sciences and medicine.

This book was released on 2016-05-25 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological responses after maximal and submaximal exercise are routinely monitored in a plethora of diseases (e.g. cardiovascular diseases, cancer, diabetes, asthma, neuromuscular disorders), and normal populations (e.g. athletes, youth, elderly), while slower or irregular post-exercise recovery usually indicates poor health and/or low fitness level. Abnormal post-exercise recovery (as assessed via blunted post-exercise heart rate dynamics) helps to predict the presence and severity of coronary artery disease, while differences in recovery outcomes in athletes might discriminate between fit and unfit individuals. Disturbances in post-exercise recovery might be due to acute or persistent changes in: (1) adaptive responses mediated by the autonomic nervous system and vasodilator substances, (2) cellular bioenergetics, and/or (3) muscular plasticity. Preliminary evidence suggests possible role of time-dependent modulation of nitric oxide synthase and adenosine receptors during post-exercise recovery, yet no molecular attributes of post-exercise recovery are revealed so far. Currently several markers of post-exercise recovery are used (e.g. heart rate measures, hormone profiles, biochemical and hematological indices); however none of them meets all criteria to make its use generally accepted as the gold standard. In addition, recent studies suggest that different pharmacological agents and dietary interventions, or manipulative actions (e.g. massage, cold-water immersion, compression garments, athletic training) administered before, during or immediately after exercise could positively affect post-exercise recovery. There is a growing interest to provide more evidence-based data concerning the effectiveness and safety of traditional and novel interventions to affect post-exercise recovery. The goals of this research topic are to critically evaluate the current advances on mechanisms and clinical implications of post-exercise recovery, and to summarize recent experimental data from interventional studies. This knowledge may help to identify the hierarchy of key mechanisms, and recognize methods to monitor and improve post-exercise recovery in both health and disease.

Book excerpt: ABSTRACT: The study was designed to determine the effects of acute resistance exercise on heart rate variability (HRV) and central blood pressure (CBP) in women, specifically during the recovery period. Eight physically active, overweight women with an average body mass index (BMI) of 27.16 ± 1.76 kg/m2, who were also untrained in regards to resistance exercise, participated in the study. Subjects completed three study sessions. During the first session, subject descriptive data was obtained and a familiarization of the resistance protocol was conducted. Sessions two and three consisted of either a control or the total body resistance exercise session. HRV and CBP values were obtained at the beginning of the session and at multiple time points during the recovery time period, totaling 60 min. The primary finding was the significantly decreased HRV component, SDNN (standard deviation of N-N's) for 20 min following acute resistance exercise followed by a return of values back to baseline at the end of recovery. The depression of HRV was expected after resistance exercise, however the current study has demonstrated the extent of the effect of the exercise in untrained, overweight women. Both CBP and peripheral blood pressure did not show significant differences between conditions and time. Post exercise hypotension was expected after exercise, but did not occur in the present study. The current study demonstrated a short effect of acute resistance exercise on HRV, but not blood pressure values. HRV values returned to baseline at the end of recovery.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the age-related changes associated with normal aging is the inability to maintain normal blood pressure homeostasis, a common clinical condition known as orthostatic intolerance. There are little data on the effects of strength training in healthy adults and orthostatic intolerance, and only one study on strength training and elderly adults diagnosed with orthostatic intolerance. Therefore, the purpose of the present study was to evaluate the effects of resistance training on the cardiovascular respones of elderly individuals during an orthostatic challenge. Thirteen subjects were assigned to either a resistance (RES; n=7; 66"5yrs.) or a control (CON; n=6; 71"6yrs.) group. During the 12-week treatment period, the RES trained 2x/wk, while the CON was asked not to change their normal lifestyles. The resistance training consisted of 3 sets of 8-12 repetitions using 12 machines at approximately 22% to 57% of 1RM. Before and after the training and control period, subjects were tested using a 70 degree head-up tilt. Tilt consisted of 30 minutes of supine rest while heart rate (HR) was recorded every minute and blood pressure (BP) was taken every 5 minutes. After the rest period, subjects were tilted to 70 degrees for 30 minutes unless subjects experienced presyncopal symptoms. During the tilt period, HR and BP were recorded every minute. After the tilt, subjects were placed in a supine position for 15 minutes of recovery, HR was taken every minute, and BP was taken every 5 minutes. A 2X2X8 (testXgroupXtime) Repeated Measures Analysis of Variance was used to analyze data. Significance was accepted at p is less than or equal to 0.05. After the 12 weeks of training, the RES significantly increased upper (46"24 to 55"29kg) and lower (62"20 to 80"31kg) body strength while the CON showed no changes. Body composition measurements by DEXA showed lean mass to increase significantly (50.5"12.9 to 52.7"13.1kg) for the RES group, while the CON showed no changes. Of the 13 subjects only 9 subjects completed the pre and post tilt tests. Of the 9 completing both tilt periods, there were no significant differences between groups for any of the dependent measures of HR, systolic blood pressure, diastolic blood pressure and mean arterial pressure. In conclusion, this study demonstrated that a resistance training program was well tolerated and improved strength and lean mass in the RES. However, training did not help these individuals improve cardiovascular responses to an orthostatic challenge.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Exercise training has consistently been shown, in the research literature, to be an effective non-pharmacological alternative to treat hypertension (HTN). However, the underlying mechanism that accounts for the reductive and preventive effects, induced by exercise have not been clearly established. To our knowledge, no study has examined the effect of an aerobic exercise-training program on prehypertension (resting blood pressure between 120/80 - 139/89 mm Hg) and the underlying variables that may exacerbate the disease's development in apparently healthy African American women. Therefore, the aim of the present study was to investigate the effects of a 10-week aerobic exercise-training regimen on total peripheral resistance (TPR), heart rate variability (HRV), and prehypertensive blood pressure status in apparently healthy African American women. Twenty-three prehypertensive African American women served as study participants. Each participant was required to meet all inclusionary criteria which included: being an African American woman between the ages of 30-45 years, a sedentary lifestyle, non-smoking status, body mass index between 25-35 (kg·m[superscript -2]), and a prehypertensive blood pressure status. A VO[subscript 2 peak] and submaximal exercise test were conducted on the cycle ergometer. HRV was assessed using power spectral analys is of beat-to-beat measurements in various frequency domains. Results revealed a significant reduction in TPR in the trained group from pre to post intervention periods (pre 35.3 [plus/minus] 5.1 mm Hg · L · min[superscript -1] vs. post 26.9 [plus/minus] 4.3 mm Hg · L · min [superscript -1]) (p

Book excerpt: This study compared the cardiovascular responses to the PWC 140, cold pressor test (CPT), and isometric hand grip (IHG), to evaluate the consistency in the blood pressure response among these physical stressors. Eighteen resting normotensive males were classified as either normotensive at exercise or exercise hypertensive on the basis of their blood pressure response to the first stage of the Canadian Aerobic Fitness Test (CAFT) for their age group. Subjects were administered a 6-min PWC 140 bicycle ergometer test, a 120 sec CPT (forearm and hand immersion), and a 120 sec IHG at 30% MVC. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), stroke volume (SV), cardiac output (CO), and ejection fraction (EF) were recorded every 5 seconds during a one min resting period, during exercise, and for 3 min post exercise using a Finapress 2000 BP monitor and BoMed bioimpedance cardiac monitor. The results of this study indicate that: (1) there were no significant differences between the two groups for the cardiovascular responses to the PWC 140, IHG, and CPT with the exception of a greater CO and SV in normotensives on the PWC 140, and a higher HR in exercise hypertensives on the CPT; (2) the exercise hypertensives had a greater rate of increase in SBP and DBP than the normotensives over the first 90 seconds of the CPT; (3) there was no consistent pattern in the individual responses to the CAFT, CPT, and IHG with respect to $\Delta$SBP. It was concluded that within the context of this study, the blood pressure responses to dynamic exercise, isometric exercise, and cold stress were not consistent among the subjects and tests.

Book excerpt: Caffeine in Food and Dietary Supplements is the summary of a workshop convened by the Institute of Medicine in August 2013 to review the available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. Scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates discussed the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and identified data gaps. Caffeine, a central nervous stimulant, is arguably the most frequently ingested pharmacologically active substance in the world. Occurring naturally in more than 60 plants, including coffee beans, tea leaves, cola nuts and cocoa pods, caffeine has been part of innumerable cultures for centuries. But the caffeine-in-food landscape is changing. There are an array of new caffeine-containing energy products, from waffles to sunflower seeds, jelly beans to syrup, even bottled water, entering the marketplace. Years of scientific research have shown that moderate consumption by healthy adults of products containing naturally-occurring caffeine is not associated with adverse health effects. The changing caffeine landscape raises concerns about safety and whether any of these new products might be targeting populations not normally associated with caffeine consumption, namely children and adolescents, and whether caffeine poses a greater health risk to those populations than it does for healthy adults. This report delineates vulnerable populations who may be at risk from caffeine exposure; describes caffeine exposure and risk of cardiovascular and other health effects on vulnerable populations, including additive effects with other ingredients and effects related to pre-existing conditions; explores safe caffeine exposure levels for general and vulnerable populations; and identifies data gaps on caffeine stimulant effects.
