The Influence of Teaching Styles in Physical Education for a Healthy Lifestyle: Physical Activity and Physical Condition

The Influence of Teaching Styles in Physical Education for a Healthy Lifestyle: Physical Activity and Physical Condition

PA not only improves aspects in relation with adult and physical health, but also contributes to obtain better results in the cognitive function and academic capacities (Dudley, 2012), so school stage is considered the best moment to engage youth people in PA (Andersen, 2006; Strong, 2005); the educational system and specifically Physical Education Teachers (PET) should contribute in this regard (Siedentop, 2009). For these reasons, different researches have been focused in the multiple benefits of active and healthy life in children and youth (Janssen, & LeBlanc, 2010; Janssen, Wong, Colley, & Tremblay, 2013; Strong, 2005). There is evidence that regular PA improves body composition, cardiorespiratory and muscular fitness (Dencker et al., 2006), bone health (Fulkerson et al., 2004) and metabolic health biomarkers among children and adolescents (Physical Activity Guidelines Advisory Committee, 2008; Simons-Morton, Parcel, O'Hara, Blair, & Pate, 1988). The most prevalent morphological consequence associated with PI and reduction of PA may be the changes in BC associated with enlargement of the adipose tissue or excessive adiposity (Guerra et al., 2006), which has two well defined categories such as overweight and obesity (Bray, 1985). Although, the prevalence of excessive thinness associated with eating disorders (for example anorexia) is a current concern during adolescence also (Hoek, 2006).

Bilingual physical education: the effects of CLIL on physical activity levels

Bilingual physical education: the effects of CLIL on physical activity levels

Therefore, due to the need to ensure healthy levels of MVPA and the concern that the amount of phys- ical activity carried out in PE lessons could be a ff ected (Coral et al. 2017; Martínez and García 2017), further studies are required to determine whether the levels of physical activity achieved through CLIL di ff er con- siderably from healthy levels of MVPA. In this research, we have chosen to use accelerometry, a technique for quantifying acceleration patterns based on high-frequency recordings, to test this as rigorously and accurately as possible, since the scienti fi c literature describes it as one of the most reliable and objective ways of measuring physical activity (Murillo et al. 2014). Accelerometers have been found to be one of the most objective tools to measure the amount of physical activity (Calahorro et al. 2015), and they have been increasingly used to measure the physical activity of school children (Rowlands et al. 2014). To address the above concerns, the present study investigates if the use of CLIL a ff ects the students ’ level of MVPA and which are the main reasons underlying the phenomenon.

Biomarkers of physical activity and exercise

Biomarkers of physical activity and exercise

ness, muscle damage, hydration/dehydration, inflam- mation, oxidative damage, fatigue, overtraining, etc, which facilitate the evaluation of the response of the human body at the different levels of physical activity or training being carried out. Biomarkers can be used to measure the impact of training on the long term or the acute effect of exercise. The value or concentra- tion of a biomarker depends on many factors, as the training status of the subject, the degree of fatigue and the type and duration of exercise, apart from age and gender, among others. Climate can also play a role, mainly temperature, humidity and wind speed. Exer- cise can be classified according to the duration as the following: around 20s (demand for anaerobic energy up to 90%), exercise lasting 20s to 1 min (aerobic and anaerobic energy) or exercises that extend over 1 min (aerobic energy more than 50%). Intensity is also an influencing factor on biomarker concentration. Most of the biomarkers are measured in blood, urine and saliva. In elite sports, non-invasive samples like urine and saliva have a preference. Other useful biomarkers are body composition (specifically muscle mass, fat mass, weight), physical fitness (cardiovascular capa- city, strength, agility, flexibility), heart rate and blood pressure.

Physical activity, energy balance and obesity

Physical activity, energy balance and obesity

This factor will, on many occasions, lead to a failure of treatment. In order of frequency lack of motivation (85%), too much work, lack of time, tiredness, laziness, all other kinds of inconveniences or lack of health (5%) are the main complaints of patients. Few people claim lack of health (less than 5%) in comparison with those who claim lack of motivation (more than 85%) 12 . Some patients wait for a ‘miracle cure’. They are not interested in changing physical or dietetic habits or perhaps are looking for a definitive weight reduction in a short time. This type of patient has visited countless doctors previously. Jakicic 26 proposes a kind of survey or an evaluation method of this predisposition step to behaviour change towards physical training, as shown in Table 3. According to the predis- position step where the patient is located, we shall project a different type of activity, and this will also influence the success rate. Setting up a programme of physical training always finds obstacles such as: ‘I do not have time’ and/or ‘it is monotonous and boring’. To combat this, the pro- fessional must try to introduce an intermittent physical training programme or to incorporate some modifications in the patient style of life in order to increase the energy costs 24 . Different routine activities may be useful for that purpose: walking up the stairs instead of taking the lift, parking the car farther away from the office and walking the rest of the way and so on can contribute to raise the caloric expense without changing the daily routine too much, thus increasing physical activity in those patients unwilling to start a programmed exercise plan. A guide- line for intermittent activity would be to spread the pro- grammed time for routine physical activity into several sessions or working periods through the day 30 .

Association between physical activity, physical fitness and cognitive performance in elderly

Association between physical activity, physical fitness and cognitive performance in elderly

ABSTRACT The aim of the study was to analyze the association between physical activity level (PAL), physical fitness (PF) and cognitive performance (CP) of the elderly. Participated in data collection 43 men with a mean age of 64.38 years (SD = 3.35) and 40 women with a mean age of 64.79 years (SD = 3.22), all residents of the city of Recife (PE), which were selected by convenience. The PAL was evaluated on the transport, work, household activities and leisure domains. The PF was evaluated by the upper and lower member muscle strength, flexibility (low back and shoulder) and cardiorespiratory endurance tests. The tests of episodic, work and semantic memory, attention and executive function (planning), evaluate the DC. Among men, PAL in transport domain was associated with semantic memory (r = .333; p = .036); among women cardio respiratory endurance was associated with work memory (r = .403; p = .007). The results suggested that PAL, PF and CP of the elder subjects may be selectively associated.

Physical activity assessment in the general population; validated self-report methods.

Physical activity assessment in the general population; validated self-report methods.

Self-reported questionnaires have been commonly used to assess physical activity levels in large cohort stu- dies. As a result, strong and convincing evidences that physical activity can protect health are widely recogni- zed. However, validation studies using objective measu- res of physical activity or energy expenditure (double labelled water, accelerometers, pedometers, etc.) indica- te that the accuracy and precision of survey techniques are limited. Physical activity questionnaires could fail in estimating particularly non-vigorous physical acti- vity. They have a disproportionate focus on volitional type exercise (i.e. biking, jogging, and walking), while not capturing the activities of daily living and low to moderate intensity movements. Energy expenditure es- timates from these data are not recommended. On the other hand, despite objective tools should be the measu- rement of choice to assess PA level, self-reported ques- tionnaires remain valid, and have many advantages. i.e. low costs. These kind of recalls are designed and vali- dated for different age groups and provide value and important information, mainly about physical activity pattern. Future studies will require more precision and accuracy in physical activity measurement than those provided by traditional survey methods. We can conclu- de that probably a mixed approach that combines both the objective and subjective techniques involving novel devices and electronic capture of physical activity ques- tionnaires will be more effective.

Influence of parents and physical education teachers in adolescent physical activity

Influence of parents and physical education teachers in adolescent physical activity

Regarding sex influence on engaging in PA, results showed it is a major issue. Near 20% of female participants reported that they do not engage in any weekly PA, while this num- ber was 9% for males. Regarding regression analysis, sex was not significant for the vigorous PA model, but it was important for moderate, mild and total PA (OR values of 2.26, 1.71 and 2.19 respectively). The absence of differ- ences in vigorous PA could be due to the questionnaire used. Students were asked about ‘‘dance and sports’’, being an activities more proper of girls, compared with the activities in, i.e., moderate PA, ‘‘jumping, running, playing with a ball or other similar games’’. Differences in PA by sex have been previously studied and it is well established that, in general, females report a higher level of sedentary lifestyle than males (Bauman et al., 2012). There are three major themes that affect girls’ physical activity, perceptual influ- ences (i.e. girls need to feel and look feminine or they have to have fun during physical activity); interpersonal influ- ences (i.e. ability comparison and competition or family, peer and teacher influences); and situational influences, such as accessibility and availability or physical activity and gender role (Standiford, 2013). Social environment must improve girls chance to be physically active and help them to increase their level of PA so parents not only can influence children through encouragement, but by being a role model they engage them in PA or they support the type of activity the children choose (Wright, Wilson, Griffin, & Evans, 2010). There is a need for more studies analyzing the effects of par- ents’ and teacher’s influence in adolescents to be physically active, mostly longitudinal studies.

Self-efficacy for physical activity in adults

Self-efficacy for physical activity in adults

ABSTRACT Self-efficacy to regular practice of physical activity (PA) can be defined as the ability to keep practicing exercises even with some obstacles that could appear. It is constituted through the influence of 4 main sources: mastery experiences, vicarious experiences, social persuasion and physiological and affective states. The aim of the study was to measure the level of self-efficacy to the regular practice of PA, its construction sources and correlate the level of self-efficacy with each one of the sources. An amount of 196 practitioners of PA took part in this study. The results showed that the level of self-efficacy was 111.19 points in scale that can range from 18 to 162 points. The most prominent source in the construction of self-efficacy was the social persuasion, with an average of 27.64 points in scale that can range from 4 to 36 points. For the correlations, it was used the Pearson coefficient (r). Mastery experiences stood out among the other sources (r = .30). The results agree with the literature, establishing the importance of the encouragement of close people in the maintenance of the behavior to practice PA, as well as to observe positive models, success experiences and feel comfortable during the exercises.

Physical activity program improves aspects of depression physical fitness of chemical dependents

ABSTRACT The aim of this study was to verify the effects of leisure time physical activity on the symptoms of anxiety and the body fitness of chemical dependents and analyzed some physical variables such as health promotion. By means of experimental study without control group in the Center of Rehabilitation and Amparo Bom Jardim - District of Interland - Anápolis - Goiás. Participated in the study 8 male adults, in voluntary treatment in the unit. Twelve interventions were performed. After an initial of intervention, the BECK anxiety and depression questionnaire and the physical fitness tests were applied before and after the. After the intervention, the participants performed a higher number of upper limb flexions (p = 0.03) and ran a greater distance (200m) in the cardiorespiratory fitness test (p = 0.002). It was recorded through the inventory of depression of BECK that 4 inmates were in a state of minimal depression and 4 had a moderate depression score. With the intervention the score was reduced from 9 (5) to 3 (3) (p <0.001).

Relationships between physical activity, physical fitness, somatic fitness, and coordination along childhood and adolescence

Relationships between physical activity, physical fitness, somatic fitness, and coordination along childhood and adolescence

ABSTRACT The two main goals of this review were to understand how the relationships between physical activity, physical fitness, somatic fitness, and coordination are established along the motor development of children and adolescents, and how they would influence their future lives. The web based bibliographic database B-On was searched for peer-reviewed publications during the last decade (2000 to 2009). Search criteria included all articles on relationships between any two of the above named factors. Although different methodological designs and variables were found as markers for the same factor, overall results suggested the existence of a clear positive relationship among physical activity, physical fitness, somatic fitness, and coordination from childhood to adolescence, with a special relevance for the relationship between physical activity and coordination. It was also noted a renewed interest on physical activity and motor coordination developmental characteristics and relationships as well as on their lifelong health effects.

Use of pedometers to promote physical activity in older mexican american females

Use of pedometers to promote physical activity in older mexican american females

The public is expected to be knowledgeable about the health benefits derived from physical activity, but the elderly should be especially aware that exercise could make the difference between mobility and dependability. Many health ailments reported by the elderly result from a sedentary lifestyle and the lack of proper nutrition. A consistent performance of daily activities such as stair climbing and yard work is associated with a lower risk of death in persons in their seventies and early eighties, additionally, people can prolong their lives without vigorous exercise. Physically active elders have a positive quality of life without disability as compared with sedentary adults (5). For healthy older adults, physical activity has a protective effect against various disease while enhancing levels of functionality.

Physical activity and health assessment in children and adolescents: application and usefulness of Physical Activity Questionnaire (PAQ)

Physical activity and health assessment in children and adolescents: application and usefulness of Physical Activity Questionnaire (PAQ)

and certain psychological indicators (sports competition, body satisfaction, anxiety) 6-8 . The PAQ-C have acceptable reliability and convergent validity 9 . The mean of all items is used to indicate level of PA. A high score indicates higher levels of PA. Moreover, attempts to obtain cut-off points from PAQ-C final score have been reported for English children 10 . In addition, this questionnaire has adequate validity and reliability in other countries 9 , although the validity and reliability assessed varies by ethnicity and requires additional development to be a useful measure of physical activity in American and European children from diverse ethnic populations 11 . However, not enough is known about the capacity of PAQ-C to estimate PA measured objectively. Moreover, discrepancies and high variability in children’s PA measured by accelerometers around the world have been reported, which may introduce a bias in validation studies 12,13 . So transcultural validation of PA questionnaires will allow us to compare results among countries and a more reliable and valid assessment of PA in each country.

Physical activity, hydration and health

Physical activity, hydration and health

Since the beginning of mankind, man has sought ways to promote and preserve health as well as to prevent disease. Hydration, physical activity and exercise are key factors for enhancing human health. However, either a little dose of them or an excess can be harmful for health maintenance at any age. Water is an essential nutrient for human body and a major key to survival has been to prevent dehydration. However, there is still a general controversy regarding the necessary amount to drink water or other beverages to properly get an adequate level of hydration. In addition, up to now the tools used to measure hydration are controversial. To this end, there are several important groups of variables to take into account such as water balance, hydration biomarkers and total body water. A combi- nation of methods will be the most preferred tool to find out any risk or situation of dehydration at any age range.

The influence of individual, social and physical environment factors on physical activity in the adult population in Andalusia, Spain

The influence of individual, social and physical environment factors on physical activity in the adult population in Andalusia, Spain

Some studies reveal that the most disadvantaged groups have a more marked perception that their neighbourhoods are not attractive, have more traffic and are more stressful for physical activity [9]. Physical environmental factors such as perception of safety in a neighbourhood, its attractiveness, the presence of passable pavements, open public spaces, leisure centres and green spaces, have been found to have a major influence on rates of physical activity in other studies, after adjustment according to socio-demographical variables such as age, educational level, ethnic groups, etc. [15,16,33]. These studies suggest that action taken based on environmental innovations could favor more active lifestyles [17,19] and that in order to increase physical activity, it is necessary to consider the way in which space is used [5,34].

TítuloRelación entre el nivel de actividad física y la motivacion de docentes de educación física

TítuloRelación entre el nivel de actividad física y la motivacion de docentes de educación física

If we want to generate motivation in our PE students, it is necessary to analyze what the teacher has in terms of the physical activity carried out. The objective was to analyze the relationship between the level of moderate-vigorous physical activity and the motivational climate of physical education teachers (PE). Participated were 125 teachers (71 men and 45 women) of PE from Costa Rica, with an average age of 40.12 ± 13.62 years. Five practical jump rope workshops were developed under the attitudinal style. The SOFIT program was used to record the time and intensity of the physical activity performed and the motivational climate questionnaire perceived in sport-2 (PMCSQ-2). A discussion group was also held with 10 of the teachers. The variable of cooperative learning (p=.022) and that of the important role of the student (p=.039) correlated significantly with the index of moderate-vigorous physical activity. The variable of unequal recognition among partners did it in an inverse way (p=.032). The teachers positively evaluated the training received in order to rethink the importance of the role of the PE teacher in the classroom. It is important to continue working in the training of teachers on bodily practices that generate motivation in themselves, as it guarantees to a greater extent that it is implemented in the classroom.

TítuloPhysical activity and fitness levels of Physical Education and Sports teacher Department students during the graduation

TítuloPhysical activity and fitness levels of Physical Education and Sports teacher Department students during the graduation

To determine the level of physical activity, the long form of the International Physical Activity Questionnaire (IPAQ), whose reliability and validity were tested for adults between 15 and 69 years of age in Turkey (Sağlam, 2010), was applied. The participants were asked about the physical activities they performed for at least 10 minutes a day in the last week, and the duration of their intensive physical activities, moderate-intensity activities, and walking were determined. The metabolic equivalent (MET) unit was used to indicate the level of physical activity. According to this, a person consumes 3.5 ml/kg/min of oxygen per body weight during rest (1 MET = 3.5 ml/kg/min). IPAQ results calculate the amount of energy that people spend in physical activity during the week in MET min/week, assuming 8 MET is spent for severe physical activity, 4 MET for moderate-intensity activity, and 3.3 MET for walking. As a result of the calculation, those whose physical activity level was <600 MET min/week were classified as inactive, >600 - 3000 MET min/week as minimum active, and <3000 MET min/week as HEPA active (Wanner et al 2016).

Psychometric properties of the task and ego orientation in sport questionnaire (TEOSQ) adapted to the mexican context

Psychometric properties of the task and ego orientation in sport questionnaire (TEOSQ) adapted to the mexican context

Viira Roomet, Institute of Sport Pedagogy and Coaching Science, University of Tartu, Estonia The purpose of this study was to examine the longitudinal relationships between psychosocial variables and physical activity in adolescence. A total of 203 14- year old boys and girls were studied. A follow-up measurement was carried out with the same subjects one year later. The variables assessed included self-reported moderate-to-vigorous physical activity (MVPA) and psychosocial variables. Results indicated that time barriers, body satisfaction, friends’ attitude, grade point average and enjoyment of physical activities were significant predictors of physical activity for boys in the first measurement. Mother’s level of physical activity, enjoyment of physical activity, time barriers, friends’ and coache’s attitude emerged as predictors for girls. In follow-up measurement, enjoyment of physical activity, fees paid by parent, fathers’ attitude, friends’ attitude, time barriers and home environment were consistent predictors of physical activity for boys. For girls, time barriers, body satisfaction, use of afternoon time, enjoyment of physical activities, friend’s attitudes, and parents’ level of physical activity were significant predictors of physical activity. The relative importance of determinants seems to differ for girls and boys and the pattern of these determinants appears to change over time.

TítuloNivel de actividad física cardiosaludable en Educación Física en educación primaria: expectativas y algunas evidencias

TítuloNivel de actividad física cardiosaludable en Educación Física en educación primaria: expectativas y algunas evidencias

The high sedentary rate of children and youth in Spain encourages us to identify possibilities and propose alternatives to reverse this situation.The ex-post facto, retrospective and comparative cross-sectional study basically consisted of identifying and comparing the level of physical activity (PA) achieved in Physical Education (PE) by 43 boys and 37 girls 6th grade Primary schoolchildren (11.86 ± 0.34 years) randomly selected from 26 centers of the Community of Madrid, according to the recommended level. For the PA analysis, the heart rate (HR) was continuously recorded by means of Polar® monitors during the PE classes in a school week, deriving from the recorded HR data the amount of time spent in an effort of ≥50% HR reserve which is equivalent to a heart-healthy PA of moderate to vigorous intensity (MVPA). The main results of the statistical analysis, whose level of significance was established at p <0.05, showed that the subjects accumulated in MVPA an average time equivalent to 21.3 ± 18.1% of the programmed weekly PE time, being similar in boys, 21.1 ± 18.9%, and in girls, 21.5 ± 17.5% (p = 0.77).In the literature, a great diversity of results is observed. However, our findings are similar to some studies that, like ours, show that the level of PA reached by schoolchildren is lower than ≥50% of the PE time recommended. The results show that the boys and girls of the sample spent in MVPA a similar proportion of PE time, a level that, in addition, is considered insufficient to generate benefits in cardiovascular health.
