Functional Inactivation of the Genome-Wide Association Study Obesity Gene Neuronal Growth Regulator 1 in Mice Causes a Body Mass Phenotype
2012
To date, genome-wide association studies (GWAS) have identified at least 32 novel loci for obesity and body mass-related traits. However, the causal genetic variant and molecular mechanisms of specific susceptibility genes in relation to obesity are yet to be fully confirmed and characterised. Here, we examined whether the candidate gene NEGR1 encoding the neuronal growth regulator 1, also termed neurotractin or Kilon, accounts for the obesity association. To characterise the function of NEGR1 for body weight control in vivo, we generated two novel mutant mouse lines, including a constitutive NEGR1-deficient mouse line as well as an ENU-mutagenised line carrying a loss-of-function mutation …
Effects of a weight management program delivered by social media on weight and metabolic syndrome risk factors in overweight and obese adults: A rand…
2017
Author(s): Jane, Monica; Hagger, Martin; Foster, Jonathan; Ho, Suleen; Kane, Robert; Pal, Sebely | Abstract: IntroductionThe aim of this project was to evaluate the effectiveness of using social media to augment the delivery of, and provide support for, a weight management program delivered to overweight and obese individuals during a twenty four week intervention.MethodsParticipants randomly divided into either one of two intervention groups or a control group. The two intervention groups were instructed to follow identical weight-management program. One group received the program within a Facebook group, along with a support network with the group, and the other intervention group receive…
Strategies to change body composition in older adults: do type of exercise and dose distribution matter?
2020
Background: This study aims to analyze changes in sedentary elderlies' body composition, comparing the impact of two dose distributions: continuous (60 min/session) vs. accumulated (30 min/session in the morning and 30 min/session in the afternoon), on two types of physical exercise programs (multicomponent-training [MCT] vs. walking interval-training [WIT]). Methods: Forty-six sedentary overweight elderly (71.3±4.3 years) were evaluated by bioimpedance with a pre-post 2x2 factorial design. Participants were distributed in four homogeneous groups, considering gait and health parameters. Results: The overall sample showed significant improvements in fat mass (% and kg) and fat-free mass (kg)…
Overweight Adolescents’ Self-Perceived Weight and Weight Control Behaviour: HBSC Study in Finland 1994–2010
2012
Introduction. Overweight and perception of being overweight, may lead adolescent to lose weight. The aim of the present study was to investigate overweight adolescents’ self-perceived weight, body dissatisfaction, and weight control behaviour during 1994–2010 in Finland.Methods. The country-representative, cross-sectional data of 15-year olds were obtained from the Health Behaviour in School-aged Children (HBSC) study, conducted in 1994 (; males: 48%), 1998 (; 49%), 2002 (; 50%), 2006 (; 47%), and 2010 (; 48%).Results. The majority of overweight boys (62–69%) and girls (89–100%) assessed themselves as too fat, and their body image was lower than in nonoverweight adolescents. The highest pre…
Patterns of rapid weight loss in elite sambo athletes
2021
Abstract Background Rapid weight loss (RWL) is commonly practiced in combat sports. Both magnitude and methods used to induce RWL are largely similar among combat sports, but currently, there is no data on RWL methodology used by sambo athletes. Therefore, the aim of this study was to determine RWL procedures sambo athletes apply to lose weight rapidly. Methods The sample consisted of 199 participants, of which 132 males and 67 females who participated in the World Sambo Championship 2020 held in Novi Sad, Serbia. Each participant received RWL questionnaire that was available in multiple languages, and every participant was instructed how to fill it out. Results Almost 87% of sambo particip…
Lift weights to fight overweight
2014
Although resistance training (RT) has long been accepted as a means for developing and maintaining muscular strength, endurance, power and muscle mass, its beneficial relationship with health factors and chronic disease has only recently been recognized in the scientific literature. Prior to 1990, resistance training was not a part of the recommended guidelines for exercise training and rehabilitation for either the American Heart Association or the American College of Sports Medicine (ACSM). In 1990, the ACSM recognized resistance training as a significant component of a comprehensive fitness programme for healthy adults of all ages, a position subsequently confirmed few years after. At pr…
Attempts to lose weight among overweight and non-overweight adolescents : a cross-national survey
2007
Background: Despite the global obesity epidemic, few studies have performed cross-national comparisons of adolescents' attempts to lose weight and weight control practices. This study aims to investigate matters mentioned above by weight status in Europe, Israel, and North America. Methods: Nationally representative samples of adolescents from over 30 countries completed an anonymous, standardized questionnaire as part of the Health Behaviour in School-aged Children 2001/2002 survey. The prevalence and likelihood of attempts to lose weight were determined. The effect of weight status, self-perception of overweight, age and country of residence upon the likelihood of current attempts to lose…
