Filter by:The study aims to provide insights into how menstrual cycle phases impact appetite responses to resistance exercise in young women. Healthy young women will participate in four trials: the exercise session in the follicular phase, the exercise session in the luteal phase, the control session in the follicular phase, and the control session in the luteal phase. Various measurements will be taken, including subjective appetite perceptions, appetite hormones, food preferences, lactate levels, estradiol levels, progesterone levels, and energy intake.
This study primarily aimed to investigate effects of breaking up prolonged sitting with intermittent brisk walking in healthy young individuals on (1) post-trial human behaviours including energy intake and physical activity under free-living conditions and (2) cognitive performance in a simulated workplace environment.
The goal of this clinical trial is to see if the enhanced HMZ 2.0 intervention with new control system/digital platform to regulate gestational weight gain (GWG) and impact maternal-infant outcomes while collecting implementation data works and can be given to other pregnant women in various settings. The question this study aims to answer are: 1. Does the new intervention manage GWG? 2. Does the new intervention have any influence on sleep and eating behaviors and infant outcomes. 3. Does the new platform and other data collected help inform how well the research and information can be used in health care settings? 144 pregnant women with overweight/obesity will be randomized to either the HMZ 2.0 intervention or attention control groups from ~8-36 weeks gestation. All participants will be asked to: 1. Weight themselves and wear an activity monitor each day over the study. 2. Complete online surveys at either a weekly or monthly level about their thoughts, attitudes, and behaviors on GWG, physical activity, eating behaviors, sleep, their anxiety, depression, and stress. 3. Attend weekly sessions with a registered dietician. The weekly sessions will differ based on intervention group. The HMZ 2.0 intervention group will receive education, create and follow goal-setting and action plans, self-monitor their behaviors, and receive feature evidence and fetal growth facts. Education, goals, and self-monitoring will focus on GWG, physical activity, eating behaviors, sleep, self-regulating behaviors and emotions, and preparing for labor/delivery and postpartum. The attention control group will receive weekly sessions on preparing for labor/delivery and benefits of behavioral pain management strategies (e.g., mindfulness-based relaxation, imagery, music, massage, deep-breathing) to help with pain after childbirth without medicine.
The objective of the study is to quantify the relationship between physical activity, metabolic function, and appetite in adolescents. To do this we will test our working hypothesis that high levels of regular moderate-to-vigorous physical activity (MVPA), as opposed to body weight status, results in a metabolic phenotype consisting of enhanced metabolic function and proper regulation of appetite. We will randomly assigning sedentary overweight/obese adolescents (N=44) to either a control or structured-exercise group for three months.
This project aims to investigate the impact of acute bout of submaximal exercise under different pre-exercise dietary conditions (fasted state versus high carbohydrate breakfast versus high protein breakfast) on postprandial glycaemic, appetite regulation and energy balance in active healthy women.
The purpose of this project is to investigate the effects of breaking up prolonged sitting on postprandial metabolic responses, gut hormones secretion and energy balance in sedentary overweight and obese adults.

10 healthy, male, participants will complete a a 5-day baseline assessment (days -5 to -1) and two consecutive 5-day periods of controlled exercise to increase oxidative capacity (3 days of aerobic exercise per period, 15 kcal/kg FFM/day energy expenditure cycling) and energy intake (15 days in total, with a testing session on morning 16). This will achieve states of energy balance (EBÍž energy availability - EA - 45 kcal/kg of fat free mass (FFM)/day), required for weight maintenance (days 1 - 5), followed by energy deficit (EDÍž EA 10 kcal/kg FFM/day), required for weight loss on days 6 - 10. Over the data-collection period, participants will consume deuterium (D2O) tracer to facilitate dynamic proteomic profiling to assess the impact of the intervention on muscle quality (primary outcome measure). Muscle biopsies will therefore be collected on days -5, 1, 6 & 11, alongside daily saliva samples, and venous blood collection on days -5, 1, 3, 5, 6, 8, 10 & 11. These samples will be used to assess further, secondary, outcome measures including alterations in intra-muscular lipid profiles (lipid droplet content, morphology and lipid-droplet associated proteins in different subcellular compartments [intermyofibrillar vs subsarcolemmal]), alterations in blood metabolites and hormones and skeletal muscle glycogen concentrations. Changes in body mass, body composition and RMR will also be assessed.
The long-term goal is to develop effective, evidence-based lifestyle interventions to prevent and treat childhood obesity and related co-morbidities. The short-term goal, and the purpose of this application, is to quantify appetite and neural mechanisms of food reward in overweight/obese (OW/OB) sedentary youth and to quantify changes following the implementation of a physical activity intervention. The central hypothesis is that appetite becomes dysregulated at low levels of physical activity via neural reward pathways, and appetite control will improve following a long-term exercise intervention. The investigators consider this project a pilot study designed to generate data to be used for future external funding opportunities, demonstrate collaboration between researchers, and test the feasibility of the protocols.
