Physical endurance is the time span between the beginning of physical activity by an individual and the termination because of exhaustion. Physical endurance involves a multifaceted behaviour which can be understood by complexities. Everyone performs physical activity in order to sustain-life. However, the number of activities done are largely subject to personal choice and varies from person to person as well as for a given person over time. Physical activity like meditation/exercises are positively related to physical fitness. One needs to understand relation between physical activity, exercise, physical fitness and health. These activities can be partitioned mutually exclusively into many different ways. This paper categorizes daily physical activity into three broad subdivisions based on amount of body movements taking place are: (i) light, (ii) moderate and (iii) high intensity. These three characterizations are considered to be mutually exclusive and sum up to total energy spent by an individual. The behavior of the three factors physical activity, heart and energy generated is analyzed with the help of Fast Lyapunov indicator (FLI), Dynamic Lyapunov indicator (DLI), Small alignment index (SALI). FLI’s increase for chaotic orbits for values of R=20, Q=70 for the case of high intensity exercises and to linearly regular orbits for values of R=5, Q=8 and R=10, Q=12 in the cases of light and moderate exercises respectively. SALI’s alters through non-zero value for R=20, Q=70 while it tends to zero for values of R=5, Q=8 and R=10, Q=12. DLI’s the largest Eigen values form a definite pattern/curve for n=2000 for values of R=5, Q=8 and n=100 for R=10, Q=12 respectively as the motion stays regular plus dispersed randomly as the motion is chaotic for n=60 and for R=20, Q=70.

Purpose: This review aimed to evaluate the utility of high-intensity interval training (HIIT) programs integrated into physical education classes. Method: Searches of electronic databases from January 2008 to March 2020. Inclusion criteria: Applied to adolescents aged 10–19 years; applied in school settings; reported results on physical fitness, physical activity (PA), and motivation; at least for 4 weeks; and randomized controlled trials. Studies with adolescents with physical or intellectual limitations were excluded, as well as other interventions parallel to HIIT. Results: Fourteen studies were included. All works present significant improvements in physical fitness and PA. Improvements in body composition recorded, at most, a moderate effect size. HIIT is presented as a powerful stimulus on cardiorespiratory fitness. Improvements in PA registered, a least, a moderate effect size. Conclusions: HIIT in the school context has great potential in improving physical fitness and PA in adolescents. HIIT efficiency (about 10 min) reflects the wide applicability that these protocols can have in physical education classes and great adaptation to the facilities.

The Impact

Summary Study aim: the purpose of the present study was to survey the impact of a social media platform on physical fitness, physical activity levels and daily sitting time. Material and methods: a total of 2039 users (1445 women and 594 men) of the social media service (HeiaHeia, Helsinki, Finland) voluntarily participated in the study by answering an online questionnaire provided by a survey. Results: about 63.8% of the participants reported that the service has advanced their perceived level of physical fitness, while 36.2% reported no impact on their fitness. Most participants (71.3%) with BMI over 25 reported that the service had helped them to improve their physical fitness. Participants with BMI over 35 reported a more positive impact than in any other weight range groups. One-third of the participants (32.3%) sat for more than seven hours a day; 23.5% sat less than five hours a day. More than half of the participants (56.8%) were encouraged to be physical active during the day and aimed to reduce sitting time at their jobs during the workday. Conclusions: there seems to be a positive impact of web services that promote physical activity on the physical fitness among social media users. Although the present service is not merely well suited for physically active and physical fit users, it motivates users of all fitness levels to exercise. However, more studies are needed to clarify effects of social media on physical activity, fitness and health.

O propósito deste ensaio de revisão configura-se na delimitação de um perfil sobre a produção do conhecimento da área pedagógica, em Portugal e no Brasil, no que se refere à atividade física, aptidão física e educação para a saúde. A revisão permite identificar as seguintes áreas de problemas: a) o debate teórico sobre conceitos de saúde, as relações normativas e os objetivos dos programas; b) o enquadramento metodológico ou as estratégias de desenvolvimento de ações. As conclusões apontam que é reduzido o número de estudos que incidem sobre o problema, sendo que boa parte deles são de natureza especulativa ou configuram-se em reproduções de estudos realizados nos países mais desenvolvidos e com tradição nesta área de investigação

Purpose:This study examined the association between physical activity (PA), physical fitness, and health-related quality of life (HRQOL) among school-aged children.Methods:Participants were 201 children (91 boys, 110 girls; Mage = 9.82) enrolled in one school in the southern US. Students’ PA (self-reported PA, pedometer-based PA) and physical fitness (cardiorespiratory fitness, muscular fitness, flexibility, and body composition) were assessed in the fall. The PedsQL4.0 (Varni et al., 2001) was used to assess participants’ HRQOL (physical and mental function) in the spring.Results:PA and four components of physical fitness were positively associated with physical and mental function. Path analyses suggested physical fitness mediated the relationship between self-reported PA and HRQOL (95% CI: [.53, 1.48]), as well as between pedometer-based PA and HRQOL (95% CI: [.54, 1.53]).Discussion:Results support the conclusion that enhancing children’s physical fitness can facilitate positive outcomes including improved health related quality of life.

Fitness Levels

Despite the widespread acceptance that physical activity is generally beneficial for children’s health and improvements in the quantity and quality of evidence supporting this position, our understanding remains limited. Methodological and conceptual discrepancies still exist, including a lack of clear consensus in how to define and assess physical activity in children, a limited consideration of concurrent factors such as growth and maturation, and a general failure to address the potential interactions of biological, psychological, and social variables. As such, Chapter 24 attemps to distil the available information with a view to establishing absolute recommendations for activity and/or fitness levels that are optimal for health in children.
