Regular physical activity and physical fitness are closely related to a positive health status in humans. In this context, the muscle becomes more important due to its function as an endocrine organ. Muscle tissue secretes "myokines" in response to physical activity and it is speculated that these myokines are involved in physical activity induced positive health effects. Recently, the newly di...

BACKGROUND Increasing physical activity and decreasing sedentary time are cornerstones in the management of type 2 diabetes (T2DM). However, there are few instruments available to measure physical activity in this population. We translated the long version of the International Physical Activity Questionnaire (IPAQ-L) into French and studied its reproducibility and validity in patients with T2DM...

OBJECTIVES Studies of total energy expenditure, (TEE; kcal/day) among traditional populations have challenged current models relating habitual physical activity to daily energy requirements. Here, we examine the relationship between physical activity and TEE among traditional Hadza hunter-gatherers living in northern Tanzania. METHODS Hadza adults were studied at two camps, with minimal inter...

CONTEXT Exercise training is associated with improved insulin sensitivity (SI), but the potential impact of habitual, nonvigorous activity is uncertain. OBJECTIVE To determine whether habitual, nonvigorous physical activity, as well as vigorous and overall activity, is associated with better SI. DESIGN A multicultural epidemiologic study. SETTING The Insulin Resistance Atherosclerosis Stu...

the purpose of this study was to assess the nutritional condition and correlation between daily physical activity and obesity in 11-year old girls. the subjects were 325 11-year old students with different cultural-economical levels who were chosen by chance and then they fill out 7-day exercise, nutritional, tendency of physical activity in children and teenagers questionnaire by the help of t...

Maintaining adequate levels of physical activity is known to preserve health status and functional independence as individuals grow older. However, the relationship between determinants of physical activity (volume and intensity) and physiological factors underlying mobility (cardio-respiratory fitness, neuromuscular function and functional abilities) is still unclear. The aim of this study was...

BACKGROUND Active video games (AVGs) have gained interest as a way to increase physical activity in children and youth. The effect of AVGs on acute energy expenditure (EE) has previously been reported; however, the influence of AVGs on other health-related lifestyle indicators remains unclear. OBJECTIVE This systematic review aimed to explain the relationship between AVGs and nine health and ...

Aim: The aim of this systematic literature review and meta-analyses was to explore the relationship between physical activity and risk of new-onset atrial fibrillation (AF) or flutter (AFlu). Results: The search revealed 10 published studies that were eligible for three different meta-analyses. A meta-analysis of six case-control studies showed that risk of AF increased more than 5-fold in athl...
