Positive effects from sports are achieved primarily through physical activity, but secondary effects bring health benefits such as psychosocial and personal development and less alcohol consumption. Negative effects, such as the risk of failure, injuries, eating disorders, and burnout, are also apparent. Because…

Background: Physical activity helps people maintain a healthy weight and reduces the risk for several chronic diseases. Although this knowledge is widely recognized, adults and children in many countries around the world do not get recommended amounts of physical activity. While many interventions are found to be…

As defined by the World Health Organization (WHO), physical activity is “any bodily movement produced by skeletal muscles that requires energy expenditure.” It is one of the fundamental functional stimuli to the body, which, if regularly applied, reduces the risk of developing a series of chronic, primarily…

Self-reported data from the GEDA 2014/2015-EHIS study was used to calculate the level of compliance among adults in Germany with the World Health Organization’s (WHO) recommendations on physical activity. The WHO’s recommendations distinguish between ‘aerobic activity’ and ‘muscle-strengthening activity’. In Germany…

Background The World Health Organization has proposed that physical activity is a meaningful way to improve the quality of human life and reduce the probability of chronic non-communicable diseases and that humans should change their mindset from the actual effectiveness of physical activity in promoting health to the…

'Abdullatif Yasir H Eissa' 'Ahmed Zaki W Mohamed Elhassan' 'Gaffar Alemam A Manhal' 'Rania H Abdelgafour'] Introduction Physical inactivity is a highly prevalent modifiable risk factor for many diseases, including cardiovascular and cerebrovascular diseases, the leading causes of death. Many health institutes have…

This conceptual analysis presents an argument that a new and broader definition of physical activity is needed for educators, researchers, and policy makers. To build a case for change, this paper has four parts. First, it outlines why definitions are important. Second, the current dominant definition of physical…

'Saleem P Iqbal' 'Shama Razzaq' 'Shamaila Hassnain' 'Shehnaz Khan' 'Noor Shahid'] Introduction There are several factors such as physical inactivity, sedentary lifestyle, and diet that can be responsible for weight gain or obesity. Regular physical activity is important for better physical and emotional well-being. The…

Physical activity is a crucial aspect of health benefits in the public society. Although studies on the temporal physical activity patterns might lead to the protocol for efficient intervention/program, a standardized procedure to determine and analyze the temporal physical activity patterns remains to be developed.…

Physical activity (PA) is recognised for providing several health benefits in humans, mainly preventing and controlling chronic non-communicable diseases. However estimating PA is a challenging and expensive task. An alternative would be to devise a model to estimate PA using actigraphy devices calibrated from an…

This paper critically examines the conceptual and methodological limitations underlying the current understanding and application of VO2max in exercise science and physical activity prescription. Despite the establishment of WHO guidelines on physical activity, population-level adherence remains low. A key contributing…

Here we study how competitions affect physical activity. We focus on walking challenges in a mobile activity tracking application where multiple users compete over who takes the most steps over a predefined number of days. We synthesize our findings in a series of game and app design implications. In particular, we…

Aging is a dynamic, time-dependent process characterized by a gradual accumulation of cell damage. Continual functional decline in the intrinsic ability of living organisms to accurately regulate homeostasis leads to increased susceptibility and vulnerability to diseases. Anti-aging research has a long history…

Despite global concerns regarding physical inactivity, limited cross-national evidence exists to compare adolescents’ physical activity participation. We analysed 52 high- and low-middle income countries, with activity undertaken inside and outside of school in 2015. We investigated gender- and…

Physical activity (PA) has been widely recognized as an avenue to improve health. Researchers have also found better health outcomes among adults who participate in sport when compared to adults who participate in other forms of PA. However, little is known about the health differences between those who participate in…

The distinction between healthy and pathological ageing has led to the concept of vitality capacity (VC), which can be understood as the body’s physiological reserve. An individual’s VC can be estimated using 12 biomarkers spread across 3 domains: immune and stress response, energy and metabolism and neuromuscular…

physical activity Authors: ['Tim Althoff' 'Boris Ivanovic' 'Jennifer L. Hicks' 'Scott L. Delp' '\xadAbby C. King' 'Jure Leskovec'] While physical activity is critical to human health, most people do not meet recommended guidelines1, 2. More walkable built environments have the potential to increase activity across the…

Physical activity has positive effects on brain health and cognitive function throughout the lifespan. Thus far, few studies have examined the effects of physical activity on white matter (WM) microstructure and psychomotor speed within the same, population-based sample (critical if conclusions are to extend to the…

In a time of physical inactivity pandemic, attempts to better understand the factors underlying the regulation of exercise behavior are important. The dominant neurobiological approach to exercise behavior considers physical activity to be a reward. However, negative affective responses during exercise challenge this…

We represent physical function as a daily activity profile derived from minute-level activity data obtained via a wearable activity monitor. We constructed the daily activity profiles- representing average time spent in a set of activity classes over consecutive days--using the Osteoarthritis Initiative (OAI) data.…

'Aiden Doherty'] Introduction: Data from wearable devices collected in free-living settings, and labelled with physical activity behaviours compatible with health research, are essential for both validating existing wearable-based measurement approaches and developing novel machine learning approaches. One common way…

This paper examines the ef ects of daily exercise time on the academic performance of junior high school students in China, with an attempt to figure outthe most appropriate daily exercise time for students from the perspective of improving students' test scores. By dividing the daily exercise time into five sections…
