Regular and goal-appropriate exercise is critical to improving and maintaining both health and performance. However, the frequency, intensity, duration and type of activities needed to optimise health or achieve successful sports performance will differ considerably depending on an individual's goals and capabilities. Although sport is one of many forms of exercise that can be counted towards daily physical activity, participation in sport is not necessary to meet current physical activity recommendations. The current consensus is that the minimum amount of physical activity needed to improve and maintain good health is 30 min moderate-intensity activity/d on ≥5 d/week. The evidence supporting this consensus is based on predominantly observational evidence that performing regular aerobic (endurance)-type physical activity is associated with reduced morbidity and premature mortality from CVD, CHD, stroke and colo-rectal cancer. The exact dose needed to improve health and the slope of the dose–response gradient between physical activity and mortality for various diseases are not known, and one major limitation of the existing evidence is the lack of objective measurement of physical activity. Limited evidence indicates that a much higher dose of activity (45–90 min each day on ≥5 d/week) may be needed to prevent overweight and obesity and to avoid weight regain in previously overweight and obese individuals. The role of resistance training and heavy domestic work in reducing morbidity and premature mortality for various diseases is unclear. As most adults do not meet current recommendations there is a critical need for innovative approaches to increase physical activity across large-scale populations.

Activity Recommendations

Research on physical activity (PA) in different educational settings could elucidate which interventions promote a healthy school lifestyle in early childhood education (ECE). The aims of this study were: (a) to analyse the PA levels of preschoolers during school hours, as well as the rate of compliance with specific recommendations on total PA (TPA) and moderate-vigorous PA (MVPA); (b) to examine the role of structured movement sessions and recess time in the MVPA levels during school hours; (c) to evaluate the sociodemographic correlates of preschoolers and the school environment on MVPA behaviour during school hours. PA was evaluated with Actigraph accelerometers. Our main findings were that: (a) preschoolers engaged in very little TPA and MVPA during school hours; (b) children showed significantly higher MVPA levels on days with versus without structured movement sessions, and the contribution of the structured sessions to MVPA was significantly higher than that of recess time; (c) gender and age were associated with PA, and a high density of young children on the playground was associated with high levels of vigorous PA, whereas in the classroom, high density was associated with more sedentary behaviour. Structured PA could reduce the gap in achieving international recommendations.

ABSTRACT Objective: To assess the physical activity level (PAL) and the total daily energy expenditure (EE-TDEE) in a sample of ≥60y subjects from Niterói, Rio de Janeiro, Brazil. Methods: A convenience sample of 88 subjects recruited from recreational physical activity programs wore an accelerometer around the waist for seven consecutive days for at least 10h/day. Minute-by-minute EE was estimated from the counts per minute (CPM) data, and the daily sum yielded the TDEE. PAL (TDEE/BMR) with BMR calculated with the FAO/WHO predictive equation and a population-specific equation. Body composition was assessed by DXA. Results: Mean age (SD) was 69.2 (5.8) years, the prevalence of overweight and obesity was 36.4 and 25.0%, respectively, and excess body fat was 39.8%. The subjects spent 600min/day engaged in sedentary activities (CPM<100). Men engaged in 30min of moderate-to-vigorous physical activity (CPM≥1,952) daily, on average. The subjects were active on 34.5 and 18.0% of the weekdays and weekend days with a 1,400 steps/day difference between these days. TDEE was 1,731.5 (348.7) and 1,356.3 (223.7) kcal/day depending on the BMR prediction equation used. Mean PAL was lower than the maintenance level. Conclusions: The high prevalence of sedentary activities and the low percentage of subjects who met the physical activity recommendations indicate that physical activity programs must be adjusted so that the enrolled subjects can meet the physical activity recommendations, preferably with the activities objectively monitored. Population-specific equations improve the final estimation of TDEE and PAL. Level of Evidence I; Diagnostic studies - Investigating a diagnostic test.

The objective of the present cross-sectional study was to examine the associations of physical activity and the adherence to the Mediterranean dietary pattern (MDP) with bone mineral content (BMC) and density (BMD) in children with overweight and obesity. A total of 177 (n = 80 girls) children with overweight and obesity aged 8 to 12 years old participated in the study. Both BMC and BMD were assessed by Dual-Energy X-ray absorptiometry. Dietary patterns were assessed by the KIDMED questionnaire and two 24-hour recalls. Physical activity was assessed by accelerometers for 7 consecutive days (24 hours/day). Low adherence to the MDP was observed in 82.4% of participants. Higher physical activity levels (of at least moderate intensity) and lower sedentary time were significantly associated with BMC and BMD in children with low adherence to the MDP (all p < 0.05). No associations were observed between physical activity and BMC and BMD in children with high adherence to the MDP. In conclusion, engaging in moderate to vigorous physical activity and reducing the time spent in sedentary behavior might be particularly beneficial for improving bone health in overweight or obese children with poor adherence to the Mediterranean dietary pattern.

The role of marketing institutions is important for conducting marketing activities, so that research has a purpose for: 1) knowing the market structure of gurame fish, 2) describing the behavior of gurame fish marketing institutions, 3) knowing the performance of marketing institutions for gurame fish in Kediri Regency. Type of research is descriptive using analysis of structure, conduct, and performance. Sampling techniques using purposive sampling and snowball sampling techniques, data collection techniques by observation, direct interviews and documentation. The results of the study are based on market structure that is influenced by the number of sellers and buyers, barriers to entry and exit markets, and market information indicating that the formed market structure is oligopoly; There are still many marketing agency behaviors that harm several parties in marketing such as accounts payable, and other fraudulent practices; The marketing of gurame fish in Kediri Regecy cannot be said to be efficient because of the uneven distribution of marketing margins, costs, and profits of each institution, as well as the high margin value, costs, and profits from one of the marketing institutions, large-scale collectors.

Asthma, one of the major widespread chronic disorders among children and adolescents, has become more prevalent recently. The common manifestations of this disorder are caused by inflammatory airways that lead to airway restriction and lung hypersensitivity causing dry coughing, wheezing, and shortness of breath, all of which are combined with sleep disturbance, impaired physical activity, and reduced quality of life. The main goal of this brief review was to identify the associated variables that affect the management of asthma disease in children and young adolescents and to identify the role of physical aerobic exercise in the treatment of asthmatic children. The current review was based on prior research published in English databases such as Google Scholar, PubMed, and Embase in scientific articles published between January 2010 and October 2021 with the keywords "asthma," "children," "adolescents," "breathing episodes," "physical activity," and "physical exercise." Regular physical aerobic exercise training with moderate intensity has been shown to improve pulmonary functions, life quality, psychological conditions, and reduce asthma symptoms and EIB in children and adolescents with bronchial asthma.

En el presente estudio de la población adolescente de la Comunidad Autónoma de Canarias se evidencia que son minoría los adolescentes que cumplen las pautas o recomendaciones de actividad física, mostrando bajos niveles de práctica de actividad física de intensidad moderada y vigorosa, niveles que se muestran alejados de las recomendaciones establecidas para este grupo de edad e insuficientes para alcanzar los efectos positivos que se derivan de la práctica de actividad física, siendo estos bajos niveles más acentuados en las chicas que en los chicos. Estas evidencias justifican la necesidad de cambiar esta tendencia y promover cambios sustanciales en los hábitos de práctica de actividad física de nuestros niños y adolescentes. Para procurar este cambio, se muestran como muy adecuado, la puesta en práctica de programas de intervención extracurriculares, junto con el necesario incremento del horario lectivo que en la actualidad se destina a la materia de educación física en el vigente currículo escolar de la Enseñanza Básica. Palabra clave: actividad física, niveles de actividad física, adolescentes, recomendaciones de práctica de actividad física, análisis del patrón de actividad física, sedentarismo.Abstract: The present study about adolescent from the Canary Islands, evidence that a minority of adolescents follow the guidelines or recommendations for physical activity, showing low level of physical activity of moderate intensity and vigorous, levels which are shown away from the established recommendations for this group of age, and insufficient to attain the positive effects arising from the practice of physical activity, and these low levels are more accentuated in girls than in boys. These evidences, justify, the need to change this trend and promote substantial changes in practice habits of physical activity of children and adolescents. To ensure this change, are shown as very adequate, the implementation of physical education programs out of the school schedule, along with the necessary increase in teaching hours which now is assigned to physical education in the current curriculum of Basic Education.Key words: physical activity, physical activity level, adolescents, physical activity recommendations, physical activity pattern analysis, sedentary lifestyle.

Intense Physical Activity

Exercise is defined as any activity that causes your muscles to work and your body to burn calories. Physical activity includes swimming, running, jogging, strolling, and dancing, to name a few. Physically and mentally active people have been shown to have various health benefits. It could even help you live a longer life. In this article, we attempt to explain the beneficial effects of exercising regularly on our brain and how this helps with cognitive tasks. We also describe the various neurotrophic neurochemicals that aid in this phenomenon. We then describe the process of neuroplasticity and how exercise can help accelerate this process. Regular physical activity is one of the most important things you can do for your health. If you're worried about being harmed if you start walking or increase your level of physical activity, it is safe for most people to engage in moderate-intensity aerobic activity, such as brisk walking. Reduced emotions of state anxiety (short-term anxiety), increased sleep, and enhanced elements of cognitive performance are some of the benefits of moderate or intense physical exercise on cerebral health that happen immediately after moderate or intense physical activity (acute impact). People who engage in more moderate or intense physical activity generally have better mental processes to gain knowledge and comprehension than those who do not. Improvements in cognition, as well as performance, might be expected. For example, standardized assessments of academic achievement and performance on mental ability tests are examples of neuropsychological testing. Processing speed, memory, and executive function are all factors to consider.
