Book Synopsis The Effects of Excercise on Appetite Regulation by : Daniel Robert Crabtree
Download or read book The Effects of Excercise on Appetite Regulation written by Daniel Robert Crabtree and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of exercise on appetite and feeding responses can be influenced by several factors. Research has demonstrated that exercise-induced changes in appetite can be affected by ambient temperature. Furthermore, exercise intensity has also been shown to affect appetite and post-exercise caloric intake. The aim of this thesis was to investigate the impact of exercise at different ambient temperatures on appetite and energy intake (EI) in overweight and obese individuals. Furthermore, this thesis also aimed to examine the effects of high intensity exercise on both peripheral and central appetite regulation in lean healthy males. The findings from this thesis demonstrated that exercise in a cold environment (8°C) stimulated post-exercise EI in overweight and obese men and women compared with exercise in a neutral environment (20°C). Exercise in the heat (32°C) caused an increase in desire to eat 5 hours post-exercise compared with rest in the heat in overweight and obese individuals, however no further differences in appetite sensations were observed between trials. Findings from this thesis have also demonstrated that an acute bout of intense running suppressed neural activation within the orbitofrontal cortex and hippocampus in response to images of high-calorie foods compared with rest. Furthermore, pictures of low-calorie foods enhanced activation within the insula and putamen post-exercise compared with rest. These central regions are associated with regulating the rewarding properties of food, therefore these findings showed that high intensity exercise is capable of suppressing the rewarding properties of high-calorie foods whilst enhancing the rewarding properties of low-calorie foods immediately post-exercise. However, an acute bout of intense running enhanced central reward system activation in response to food cues compared with rest several hours after exercise. Therefore, the appetite suppressing effects of an acute bout of high intensity exercise could be short-lived.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated] It is well established that exercise plays an important role in the management of overweight and obesity. In the past, this was primarily attributed to the direct contribution of exercise to energy expenditure, however it is becoming increasingly evident that exercise may also influence appetite and energy intake. Importantly, the precise effect of exercise on appetite and energy intake appears to be influenced by specific characteristics of the exercise. In particular, high-intensity exercise appears to have beneficial (anorexic) effects on appetite and energy intake. Prolonged and continuous high-intensity exercise may however, not be tolerable and sustainable in an inactive and overweight population. An alternative may be the use of high-intensity, intermittent exercise that involves short bouts of high-intensity exercise interspersed with periods of exercise at lower intensities. However, the effects of high-intensity, intermittent exercise on energy intake and appetite regulation is not known. The research presented in this thesis examines the acute and longer term influence of high-intensity, intermittent exercise compared with traditional moderate-intensity, continuous exercise on subsequent energy intake, perceptions of appetite and appetite-related blood variables in sedentary, overweight men.

Book Synopsis The Influence of Exercise Intensity on Appetite Regulating Hormones GLP-1 and PYY in Active Healthy Adults by : Jillian R. Hallworth
Download or read book The Influence of Exercise Intensity on Appetite Regulating Hormones GLP-1 and PYY in Active Healthy Adults written by Jillian R. Hallworth and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Exercise is a known contributor to fat loss, its efficacy increasing when combined with an energy-restricted diet in order to create an energy deficit. Claims exist that exercise intensity may influence one's hunger and energy intake post-exercise, affecting the efficacy of exercise for fat loss. Additionally, women may increase energy intake following exercise to compensate for the increased energy expenditure more than men. This study used a randomized crossover design to examine the effect of exercise intensity on appetite regulating hormones GLP-1 and PYY, and subjective hunger in women, and compared these results to men following endurance cycling. Both sprint interval cycling and continuous endurance cycling influenced the concentration of GLP-1 and PYY, though not differently, and had no influence on perceived hunger. There was no significant difference in the response of these satiety hormones and hunger between men and women following endurance cycling.
Book Synopsis Regulation of Body Weight by : Claude Bouchard
Download or read book Regulation of Body Weight written by Claude Bouchard and published by . This book was released on 1996-06-19 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fact that about 30-40% of the adults in the Western world are overweight or obese testifies to the frequency of the disturbances in body weight regulation. Scientists have established that caloric intake, macronutrient composition of the diet, basal and resting metabolic rate, thermic response to food, energy expenditure associated with movement and physical activity, and preferential storage of the surplus of calories as fat or lean tissues are critical determinants of energy balance and body weight. While much has been learned, the field is poised for major advances with the advent of a variety of imaging techniques, progress in quantitative and molecular genetics, use of transgenic rodent models and of breeding experiments with informative inbred strains, availability of stable isotopes for metabolic and behavioral studies, and a growing number of useful experimental animal and human models. This volume takes an integrative approach to obesity. It is structured around four major topics: (1) the animal and human models currently available for the study of body weight regulation with their strengths and limitations, (2) the molecular and genetic basis of the regulation of body weight, (3) the metabolic and physiological mechanisms involved, and (4) the behavioral and social determinants. The 13 background papers provide a critical overview of the present knowledge base while the group reports summarize the extensive deliberations of 38 international experts. Particular emphasis has been given to promising research areas and on the advances needed to ensure a better understanding of the biological and behavioral mechanisms of the regulation of body weight, with a particular emphasis on overweight and obesity.
Book Synopsis Exercise and Appetite by : Stephanie Marie Howe
Download or read book Exercise and Appetite written by Stephanie Marie Howe and published by . This book was released on 2015 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: In endurance-trained men, an acute bout of exercise is shown to suppress post-exercise appetite and alter changes in specific appetite regulating hormones. Limited research has examined these responses in endurance-trained women. PURPOSE: To investigate the effect of exercise intensity on the appetite regulating hormones acylated ghrelin, PYY and GLP-1 and subjective ratings of appetite in endurance trained women. METHODS: Fifteen highly-trained women (18-40y, 58.4±6.4kg, VO2MAX=55.2±4.3 mL/kg/min) completed isocaloric bouts of moderate intensity exercise (MIE) at 60%VO2MAX, and 2) and high- intensity exercise (HIE) at 85%VO2MAX in randomly assigned order. In both trials, subjects ran on a treadmill until an energy expenditure (EE) of 500 kcal was achieved. Blood was drawn pre-exercise (baseline), immediately post-exercise and every 20-min for the next 60-min. Plasma concentrations of acylated ghrelin, PYY3−36, GLP-1 and subjective appetite ratings via visual analog scale (VAS) were assessed at these same time points. Food intake and physical activity were recorded 48-h before each trial. A mixed model analysis was used to examine the impact of exercise intensity (60% vs. 85% VO2max) on appetite- regulatory hormones and VAS responses over time. Where significant effects were found, post-hoc analyses were performed using the Bonferroni correction for multiple comparisons. For these same variables area under the curve (AUC) was calculated using the trapezoid method to determine total response over time. The overall statistical significance was accepted at the 5% level. RESULTS: Results for appetite hormones showed no main effect for exercise intensity or interactive effects, but a significant main effect for time; thus, data were combined across exercise intensities for each time point. Acylated ghrelin decreased (p=0.014) and PYY3−36 and GLP-1 increased (p=0.036, p
Book Synopsis Post-exercise Dietary Strategies for Regulating Appetite in Individuals with Overweight by : Courteney C. Hamilton
Download or read book Post-exercise Dietary Strategies for Regulating Appetite in Individuals with Overweight written by Courteney C. Hamilton and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Evidence suggests that exercise, despite being recommended for weight management, is not effective for weight loss partially due to increased compensatory energy intake (EI). The impact of post-exercise diet on appetite and EI requires further investigation. Objective: To determine if specific post-exercise dietary strategies, including prebiotic supplementation or fasting, differentially modulate appetite and EI after an acute bout of exercise. Methods: In a randomized crossover study, individuals with overweight received one of three recovery beverages: 1) water control (FAST); 2) sweetened-milk (SM/FED); or 3) sweetened-milk + prebiotic (SM+P) after cycling for 45min (65-70% VO2peak). EI, subjective appetite, gastrointestinal feelings, and appetite-regulatory hormones were assessed. Results: Post-exercise prebiotic supplementation increased measures of satiety and decreased EI the day following exercise. Fasting temporarily increased post-exercise hunger, but did not modify EI. Conclusions: Both prebiotic supplementation and fasting modify the post-exercise appetite response. Prebiotics may help individuals with overweight reduce post-exercise EI.
Book Synopsis Acute Exercise and Subsequent Energy Balance by : David Thivel
Download or read book Acute Exercise and Subsequent Energy Balance written by David Thivel and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical activity programs and dietary restrictions are commonly used to favor weight-loss in overweight and obese patients, by reducing energy balance. Such programs suffer of a low adherence and high drop-out due to the difficulties met by patients to concomitantly support exercise and energy restriction. Physical exercise has been proposed as a potential indirect energy intake modulator, which could be interesting in terms of obesity treatment. The impact of exercise on subsequent energy balance (intake and expenditure) and appetite has been mainly questioned among lean adults but few data are available in obese populations, particularly pediatrics. The first aim of this work was then to determine whether or not an acute bout of exercise could affect subsequent energy balance and appetite in obese adolescents (STUDY I). Then the importance of the prescribed exercise intensity (Low vs High intensity) on those energy balance and appetite modifications has been investigated (STUDY II). The results demonstrate that an intensive exercise (>70%VO2max) realized by the end of the morning favors a reduced energy balance by mainly decreasing energy intake. The induced energy intake decrease was observed within minutes after the exercise (30 minutes, lunch time), with the onset being experienced about 7 hours after, during dinner time. Data remain however contradictive concerning the post exercise macronutrient intake, and further investigations are required. No gender difference was observed in terms of post exercise energy balance and appetite adaptations. The observed energy intake adaptations were not accompanied by appetite sensation modifications, suggesting that obese adolescents are not at risk for food frustration. Within 24-h, obese adolescents' energy balance can be reduced thanks to both elevated energy expenditure and decreased energy intake when an intensive exercise is performed by the end of the morning. Such results need to be questioned as part of chronic interventions to know whether or not intensive exercise can provide a great tool to induced long term energy balance reduction (by dually affecting energy expenditure and intake) and then weight loss.

Book Synopsis Prolonged Impact of Exercise on Appetite and Energy Compensation by : Tetsuro Okada
Download or read book Prolonged Impact of Exercise on Appetite and Energy Compensation written by Tetsuro Okada and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Exercise generally leads to less than anticipated weight loss, despite inducing an acute negative energy balance. Post-exercise compensatory mechanisms that increase energy intake and decrease energy expenditure contribute to ineffective weight loss with exercise, although the precise mechanisms remain unclear. The aim of this thesis was to investigate the 3-day impact of exercise on measures of appetite and energy compensation in a healthy population of males and females. Fourteen participants completed two conditions in a randomized crossover trial: 1) 75 min exercise (75% VO2peak); and 2) 75 min sedentary control. Measures of energy intake, energy expenditure, subjective appetite, and appetite-related hormones were assessed. An acute post-exercise suppression of acyl-ghrelin was observed. Exercise increased overall measures of subjective appetite despite no increase in energy intake or change in post-exercise physical activity patterns. Overall, exercise increased perceived appetite despite no clear evidence of energy compensation through energy intake or energy expenditure.

Book Synopsis Developmental Biology of Gastrointestinal Hormones by : M. Wabitsch
Download or read book Developmental Biology of Gastrointestinal Hormones written by M. Wabitsch and published by Karger Medical and Scientific Publishers. This book was released on 2017-08-16 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gut not only represents the largest endocrine organ of the human body but is also profoundly involved in the control of metabolism through peptide hormones. Therefore, gastrointestinal hormones are acting via autocrine, paracrine, and classical endocrine pathways and regulate e.g. digestion, hunger, and satiety. Furthermore, they are important regulators of body weight, growth, and glucose metabolism, as well as of mood and behavior. Physicians and scientists in the field of pediatric endocrinology and diabetes, as well as in pediatric gastroenterology, require an extensive understanding of the origin of enteroendocrine cells, factors controlling their differentiation, hormone gene expression, secretion, function and, finally, the complex interaction with other organs, especially the central nervous system. In order to meet these needs, experts in the field have written up-to-date, comprehensive, and illustrated reviews presenting the current knowledge in the field of gastrointestinal endocrinology with a pediatric view. Those reviews comprise this latest volume of Endocrine Development.

Download or read book Weight Management written by Institute of Medicine and published by National Academies Press. This book was released on 2003-12-01 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.
