Filter by:The aim of this project is to improve the evidence-base regarding lifestyle and mental health symptoms among fitness instructors. A national cohort of fitness instructors will be invited to participate in this study by responding to an online questionnaire. The questionnaire will consist of items regarding exercise, nutrition, eating disorders, the menstrual cycle, depression, anxiety, body dissatisfaction and satisfaction, drive for muscularity and leanness, and experiences of sexual harassment. Findings from this study will provide an evidence-base for initiatives to improve/optimize mental health among fitness instructors, and also in the process of developing fitness centres to a core partner in public health and health promotion work.
The participants will visit the laboratory on 3 occasions, once for a preliminary visit and a further two occasions to complete experimental trials in a randomised order. The experimental trials will consist of cycling under two conditions; HIIE-First followed by Continuous (Trial-A) or Continuous-First followed by HIIE (Trial-B). Participants will be asked to standardise their diet for 24-hours and complete an overnight fast prior to visiting the laboratory. Participants will then complete 60-min of cycling split throughout the day into two 30-min bouts, HIIE or continuous cycling before breakfast followed by a 3.5 hour rest period before completing their remaining 30-min HIIE or Continuous cycling before lunch. Each experimental trail will last approximately 8 hours and begin at 08:00am. Throughout the trial measurements of subjective feelings of appetite, gastric emptying rate, substrate utilisation and regular blood samples will be taken. Post-trial nutritional and well-being questionnaires will be collected at 24-h post. Study hypothesis 1. The order in which continuous and HIIE is undertaken will result in differences in gastric emptying rate after ingesting a semi-sold lunch? 2. Depending on which mode of exercise is undertaken first will result in different gastrointestinal hormone responses, metabolic responses and appetite responses throughout the trial day? 3. Will the order in which different modes of exercise, undertaken within the same day effect nutritional intake and well-being 24-h after both exercise bout have been completed? 4. Is substrate oxidation effected by the order in which multiple exercise bout of different modes are undertaken within the same day.
Since severe obesity in youth has been steadily increasing. Specialized pediatric obesity clinics provide programs to aid in reducing obesity. Since the home environment and parental behavioral modeling are two of the strongest predictors of child weight loss during behavioral weight loss interventions, a family-based treatment approach is best. This strategy has been moderately successful in our existing, evidence-based pediatric weight management program, Brenner Families In Training (Brenner FIT). However, since programs such as Brenner Families in Training rely on face-to-face interactions and delivery, they are sometimes by the time constraints experienced by families. Therefore, the purpose of this study is to develop and pilot a tailored, mobile health component to potentially increase the benefits seen by Brenner FIT standard program components and similar pediatric weight management programs.
The purpose is to establish feasibility of delivering an individually-tailored, behavioral intervention to manage gestational weight gain [GWG] that adapts to the unique needs and challenges of overweight/obese pregnant women [OW/OBPW] and will utilize control systems engineering to optimize this intervention; in other words, make this intervention manage GWG in OW/OBPW as effectively and efficiently as possible.
This study is designed as an observational trial. The objective of this study is to follow-up with participants 3 years after completion of an 18-month comprehensive behavioral weight loss intervention. Outcomes of interest include change in body weight, body composition, physical activity, energy intake, and sleep. In addition, investigators will explore the associations between current physical activity, sleep, and energy intake patterns and body weight regulation.
This study is an ancillary study to the Utilizing Protein During Weight Loss to Impact Physical Function (UPLIFT) trial (NCT03074643) to evaluate the effects of diet composition (i.e., amount of protein and carbohydrate) during a 6-month weight loss intervention and 12-months of follow-up on bone phenotypes in obese older adults. Participants will receive either a protein or carbohydrate supplement along with a behavioral weight loss intervention.
To assess the effect of wearing a custom-fitted, FDA-registered, Class I device, compression garment (Obesinov, S.A.R.L.) by an individual with a BMI ≥ 35 on his/her day-to-day quality of life over a period of one year. Various measures of quality of life will be taken, including assessing an individual's level of pain, mood, self-stigma and comfort with the use of a compression garment. Additionally, to assess the impact of the compression garment on activity, strength, posture and movement of an individual with a BMI ≥35 over the period of one year.
The investigators will study the influence of initial fat cell size/number and adipose function (in particular lipolysis) on weight development over very long time periods (years). By comparing investigations of fat biopsies or blood samples obtained at baseline, the investigators will determine the association between adipose morphology/function and changes in weight or development of metabolic complications (e.g. metabolic syndrome, glucose intolerance, type 2 diabetes, dyslipidemia and hypertension).
This is a completely text-messaging based study and all data will be collected via surveys administered on a mobile phone. For this study, we will gather and analyze data on changes in body weight over a 6-month interval in individuals aged 12 and over. This will help us learn more about the normal variation in weight, over time, in the PWS population.
This study is a randomized controlled trial (RCT) of the Weight Watchers (WW) Freestyle ® (Flex® in UK) weight loss program compared to a control group following a do-it-yourself (DIY) approach for 12 months. Participants in the United States, Canada and the UK (n=360 total) will be randomly assigned to either participate in the commercially available WW program in their local community or to follow their own approach for weight loss. This study will examine the impact of the WW program on weight, fitness levels, quality of life, health behaviors and other health outcomes in overweight and obese adults after 3 and 12 months.
