BACKGROUND: Sedentarism is a risk factor for mortality that is independent of physical exercise. As indicated in the literature, there is negative compensation of non-exercise physical activity due to exercise training. The aim was to investigate potential predictor variables of physical activity compensation in post-menopausal women beginning aerobic physical exercise training. METHODS: One hundred and three post-menopausal women (mean age, 58.31 ±5.33 years) were eligible for the study...

OBJECTIVE: To study if repeated yearly training programs consolidate the transient blood pressure (BP) improvements of one exercise program into durable adaptations. METHODS: Obese middle-age individuals with metabolic syndrome (MetS) underwent high-intensity aerobic interval training during 16 weeks (November to mid-March) in 3 consecutive years [training group (TRAIN); N = 23]. Evolution of MetS components was compared with a matched-group that remained sedentary [control group (CONT); N = 26]...

New research into physical activity suggests that it is no longer sufficient just to meet minimum levels recommended by health guidelines in order to reduce cardiovascular risk. Both physical inactivity and sedentary behavior have their own health hazards and need to be addressed separately, in order to explore their different deleterious mechanisms. The aim of this review was to define and to characterize both concepts, and their relationship with major non-communicable chronic diseases. A PubMed database search was undertaken, using the following key words: physical activity, physical inactivity, sedentarism, sedentary behavior, and non-communicable chronic disease...

INTRODUCTION: Frailty and low physical activity and cardiorespiratory reserve are related to higher perioperative morbimortality. The crucial step in improving the prognosis is to implement specific measures to optimize these aspects. It is critical to know the magnitude of the problem in order to implement preoperative optimization programmes. OBJECTIVE: To characterize surgical population in a university hospital. METHODS: All patients undergoing preoperative evaluation for abdominal surgery with admission were prospectively included during a 3-month period...

Understanding the negative health consequences of a physical inactivity has been the topic of much investigation as an alarming number of adults have adopted a sedentary lifestyle. With the rise in sedentarism the field of inactivity physiology has emerged. The goal of inactivity physiology is to identify the impact in inactivity on health and develop strategies that effectively minimize the risk of a sedentary lifestyle. Arising from this field is the finding that excessive sitting is linked to increased cardiovascular and metabolic disease and all-cause mortality...

BACKGROUND: Sedentarism is associated with the development of noncommunicable diseases (NCD) such as cardiovascular diseases (CVD), type 2 diabetes, and cancer. Therefore, the identification of specific sedentary behaviors (TV viewing, sitting at work, driving, relaxing, etc.) is especially relevant for planning personalized prevention programs. OBJECTIVE: To build and evaluate a public a dataset for the automatic recognition (classification) of sedentary behaviors...

In this paper we question whether prior cross-national differences in food attitudes still exist and if so, to what extent. Due to societal evolutions such as sedentarism and globalization, international variations in food attitudes may not be as pronounced as currently believed. A cross-sectional web-based survey was carried out in the United States, the United Kingdom, France and Belgium. A total of 2167 respondents (52% women; mean age = 39.0 years, SD = 11.4) participated. To successfully combat obesity, a joint approach focusing on food choice and physical activity is required; therefore we included behavioral measures by means of choice tasks for these two important drivers...

RA is a chronic autoimmune disease characterized by high grade-inflammation, and associated with elevated cardiovascular risk, rheumatoid-cachexia and functional impairment. Sedentary behaviour (SB) is linked to heightened inflammation, and is highly pervasive in RA, likely as a result of compromised physical function and persistent fatigue. This high sedentarity may exacerbate the inflammatory process in RA, and hold relevance for disease-related outcomes. The aim of this narrative review is to provide an overview of the definition, measurement and health relevance of SB in the context of RA...

Among various factors, such as an unhealthy diet or a sedentarity lifestyle, excessive fructose consumption is known to favor nonalcoholic fatty liver disease (NAFLD), as fructose is both a substrate and an inducer of hepatic de novo lipogenesis. The present review presents some well-established mechanisms and new clues to better understand the pathophysiology of fructose-induced NAFLD. Beyond its lipogenic effect, fructose intake is also at the onset of hepatic inflammation and cellular stress, such as oxidative and endoplasmic stress, that are key factors contributing to the progression of simple steatosis to nonalcoholic steatohepatitis (NASH)...

The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT). This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index)...

BACKGROUND: The terms sedentary behavior and physical inactivity have been confusingly mixed. Although the association between physical inactivity and mortality has been shown previously in subjects with COPD, this association had not yet been investigated with regard to sedentarism. The aim of this work was to investigate the impact of sedentary behavior on mortality of subjects with COPD and to propose a cutoff point of sedentarism with prognostic value. METHODS: In this retrospective cohort study, sedentary behavior was assessed with 2 activity monitors (DynaPort and Sensewear armband) in 101 subjects with COPD from 2006 to 2011...

PURPOSE: Due to sedentarity-associated disease risks, there is much interest in methods to increase low-intensity physical activity. In this context, it is widely assumed that altering posture allocation can modify energy expenditure (EE) to impact body-weight regulation and health. However, we have recently shown the existence of two distinct phenotypes pertaining to the energy cost of standing-with most individuals having no sustained increase in EE during steady-state standing relative to sitting comfortably...

BACKGROUND: Intensity and duration of physical activity are associated with the achievement of health benefits. Our aim was to characterize physical activity behavior in terms of intensity, duration pattern, and adherence to the WHO physical activity recommendations in a population-based sample of adults from southern Germany. Further, we investigated associations between physical activity and sex, age, and body mass index (BMI), considering also common chronic diseases. METHODS: We analyzed 475 subjects (47% males, mean age 58 years, range 48-68 years) who wore ActiGraph accelerometers for up to seven days...

Disuse induces a rapid bone loss in humans and animals; hypodynamia/sedentarity is now recognized as a risk factor for osteoporosis. Hypodynamia also decreases bone mass but its effects are largely unknown and only few animal models have been described. Hypodynamic chicken is recognized as a suitable model of bone loss but the effects on the quality have not been fully explored. We have used ten chickens bred in a large enclosure (FREE group); ten others were confined in small cages with little space to move around (HYPO group)...

INTRODUCTION: Physical training programs (PTP) have shown several beneficial effects for patients with cardiovascular disease (CVD), particularly by increasing survival and quality of life. Physiological response during the effort and recovery phases of an exercise testing, is one of the strongest prognostic markers among patients with CVD. A reasonable mechanism that explains those training effects on survival is through the adaptations seen on heart rate recovery (HRR) and oxygen uptake kinetics at the post-exertional phase (RVO2)...

REVIEW
A G Dulloo, J Jacquet, J L Miles-Chan, Y Schutz
While putative feedback signals arising from adipose tissue are commonly assumed to provide the molecular links between the body's long-term energy requirements and energy intake, the available evidence suggests that the lean body or fat-free mass (FFM) also plays a role in the drive to eat. A distinction must, however, be made between a 'passive' role of FFM in driving energy intake, which is likely to be mediated by 'energy-sensing' mechanisms that translate FFM-induced energy requirements to energy intake, and a more 'active' role of FFM in the drive to eat through feedback signaling between FFM deficit and energy intake...

ᅟ: Chronic inactivity and weight regain are serious health concerns following bariatric surgery. Neighborhood walkability is associated with higher physical activity and lower obesity rates in normal weight populations. PURPOSE: Explore the influence of neighborhood walkability on physical activity and sedentarism among long-term post-bariatric surgery patients. METHODS: Fifty-eight adults aged 50.5 ± 9.1 years, with a BMI of 34.6 ± 9.7 kg/m(2) having undergone surgery 9...
