BACKGROUND: Interventions to improve physical activity (PA) among adolescents continue to be a public health priority. To promote PA more effectively, we need to identify the main factors contributing to (not) engagement in PA in the perspective of adolescents themselves. Thus, we explored the barriers and enablers for sufficient moderate-to-vigorous physical activity (MVPA) in adolescents from their point of view. METHODS: We used qualitative data collected as part of the international Health Behaviour in School-Aged Children study. We obtained data from 14-17 years old adolescents from the first year of Slovak high school. We conducted 11 online, semi-structured individual and group interviews with 24 participants in total (7 boys; mean age = 15.17, SD = 0.87) in Slovakia. We analysed the data using consensual qualitative research and thematic analysis. RESULTS: In the statements of adolescents, four main themes were identified regarding factors contributing to (not) engagement in PA among adolescents. 'Myself as a source' represents the importance of adolescents' own efforts, knowledge, physical predispositions and PA experience. 'How PA can be done' represents school as an opportunity for PA, and PA teachers and sports coaches as specialists who can create an enabling environment for sports. 'Others as a source' represents the social circle that can set a positive sports example and can encourage adolescent's efforts in PA. 'Factors outside' represents other factors that can inspire adolescents, e.g. by giving them a comfortable space and time to exercise, or can be a barrier to PA. CONCLUSION: The potential factors that include adolescents' perspectives can be more leveraged in designing supportive, inclusive, enjoyable, and skills-appropriate PA programmes.

UNLABELLED: This study uncovered the patterns of moderate-to-vigorous physical activity (MVPA) in normal-weight and overweight/obese children before, during, and after school lessons. ActiTrainer-based MVPA was assessed over 2 school days (with and without a physical education lesson [PEL] in a sample of three hundred thirty-eight 9- to 11-year-old children (50.3 % female; 29.6 % overweight/obese), in the Czech Republic, during spring 2012. MVPA was quantified based on the step count (number), MVPA duration, and MVPA heart-rate response (minutes). No differences in the MVPA based on the time during the school day were confirmed in normal-weight versus overweight/obese girls, whereas normal-weight boys significantly exceed their overweight/obese peers in step count and after-school and daylong MVPA. Active participation in PEL contributes to a significantly higher step count, exercise duration, and MVPA heart-rate response in normal-weight and overweight/obese boys (p < 0.001) and normal-weight (p < 0.001) and overweight/obese (p < 0.04) girls during school time. Moreover, active participation in PEL significantly (p < 0.04) increases the overall daily step count, duration, and MVPA heart-rate response in normal-weight boys and overweight/obese girls. Active exercise during PEL accounted for 16.7 % of the total number of steps, 25.1 % of overall MVPA duration, and 24.1 % of the MVPA heart-rate response in 9- to 11-year-old children. During days with a PEL, a significantly (p < 0.02) higher number of overweight/obese girls and a higher number of normal-weight boys achieved the duration of 60 min/day of MVPA compared with days without a PEL. CONCLUSION: Adding one PEL or an equivalent amount of MVPA to the daily school routine appears to be a promising strategy to effectively increase daily MVPA, particularly among overweight/obese girls.

BACKGROUND: Sufficient levels of moderate to vigorous physical activity (MVPA) give substantial health benefits to adolescents. This article examines trends in physical activity (PA) from 2002 to 2010 across 32 countries from Europe and North America. METHODS: Representative samples included 479 674 pupils (49% boys) aged 11 years (n = 156 383), 13 years (n = 163 729) and 15 years (n = 159 562). The trends in meeting the recommendations for PA (at least 60 min daily) were evaluated using logistic regression. RESULTS: There was a slight overall increase between 2002 and 2010 (17.0% and 18.6%, respectively). MVPA increased significantly (P ≤ 0.05) among boys in 16 countries. Conversely, nine countries showed a significant decrease. Among girls, 10 countries showed a significant increase (P ≤ 0.05). Eight countries showed a significant decrease. For all countries combined, girls were slightly less likely to show an increase in PA over time. CONCLUSIONS: The majority of adolescents do not meet current recommendations of PA. Further investment at national and international levels is therefore necessary to increase PA participation among children and adolescents and reduce the future health burden associated with inactivity.

Cíl: Zhodnotit celkovou aktivitu žen v těhotenství s nízkým rizikem, přeložit dotazník Pregnancy Physical Activity Questionnaire (PPAQ) a sledovat fyzickou aktivitu těhotnych žen pomocí tohoto dotazníku v brazilské populaci. Typ studie: Průřezová kvantitativní studie zahrnující 305 žen mezi 16 a 40 lety s nízkým rizikem těhotenství. Pracoviště: Ministerstvo veřejného zdraví, Státní univerzita v Ceará, Fortaleza, Brazílie. Metodika: Použili jsme upravenou verzi dotazníku PPAQ pro posouzení úrovně fyzické aktivity a energetického výdeje. Výsledky: Zjištěn byl vysoký počet nedostatečně aktivních těhotných žen. Nižší výdej energie byl pozorován zejména ve třetím trimestru u těhotných žen s nižší úrovní vzdělání a svobodných žen.

Objective: To evaluate the total activity performed by women with low-risk pregnancy as well as translate and pursue a cross-cultural adaptation of the Pregnancy Physical Activity Questionnaire (PPAQ) to the Brazilian reality. Design: We conducted a cross-sectional quantitative study including 305 women between 16 and 40 years of age with low-risk pregnancies. Setting: The Department of Public Health, State University of Ceará, Fortaleza, Brazil. Methods: We applied an adapted version of PPAQ to assess the levels of physical activity and the intensity in the metabolic equivalent task (MET), which could be distinguished as follows: sedentary (< 1.5 METs), light (1.5–3.0 METs), moderate activity (3.0–6.0 METs), and vigorous activity (>6.0 METs). The Kruskal–Wallis test was used to compare energy expenditure (MET) with socio-demographic variables. Results: More than half of the participants performed activities that were classified as light (51.4%). If we group the activities that were categorized as sedentary and light, this value increases to 74.7%, showing a high prevalence of insufficiently active pregnant women. Lower energy expenditure was observed in the third gestational trimester among pregnant women with lower educational level, single women, and mixed-race women (p < 0.05). Conclusion: There is a prevalence of physical inactivity during the three trimesters of pregnancy. The results validate PPAQ for the Brazilian population to serve as a basis for future public policies focused on combating the health problems of mother–infant pairs.

This study is the first to use compositional data analysis to investigate movement behaviors of elderly women and their relationships with fat mass percentage (FM%). The focus of the study is on the associations of time reallocations from sedentary behavior (SB) to light physical activity (LIPA) or moderate-to-vigorous physical activity (MVPA) with adiposity. Over 400 older adult women were recruited as part of the cross-sectionally conducted measurements of older adults aged 60+ in Central European countries. An accelerometer was used to assess daily movement behaviors. Body mass index (BMI) and fat mass percentage (FM%) were assessed as adiposity indicators using InBody 720 MFBIA. Using LS-regression, we found positive relationships of BMI and FM% with SB (relative to remaining movement behaviors) (p < 0.001 for both), while their relationship with MVPA (relative to remaining movement behaviors) were negative (p < 0.001 for both). The estimated BMI and FM% associated with a 30-min SB-to-MVPA reallocation were reduced by 1.5 kg/m2 and 2.2 percentage points, respectively, whereas they were not reduced significantly with the reallocation of 30 min from SB to LIPA. The findings highlight that SB and MVPA, but not LIPA, are significantly associated with adiposity in elderly women. The reallocation of time from SB to MVPA could be advocated in weight loss interventions in older women.

Východiska: Organizovaná pohybová aktivita (PA) může významně ovlivnit míru denní PA i sedavého chování (SB) v rámci ročních období u adolescentních dívek. Cíle: Hlavním cílem studie je porovnat míru PA a SB u dívek ve věku 11-15 let v rámci dní s tréninkovou jednotkou (TJ) a bez TJ v kontextu sezónnosti. Metodika: Studie se zúčastnilo 27 dívek navštěvujících taneční skupinu street dance. PA a SB byly měřeny akcelerometrem ActiGraph GT3X+. Měření probíhalo během školního roku 2017/2018, konkrétně pak na podzim (listopad), v zimě (březen) a na jaře (květen). Meteorologické údaje byly získány z meteorologické stanice Českého hydrometeorologického ústavu na letišti v Mošnově. Statistické zpracování dat proběhlo v programu SPSS 22 (SPSS, Chicago, IL). Pro popis PA a SB byl použit aritmetický průměr, směrodatná odchylka a interval spolehlivosti. Pro zjištění rozdílů mezi naměřenými hodnotami PA a SB byla použita analýza variace opakovaného měření. Statistická významnost pro tento výzkum byla stanovena na hladině p = 0,05. Výsledky: Analýza rozdílů ve struktuře pohybového chování v rámci dní s TJ a bez TJ ukázala signifikantní hodnoty u SB (F = 6,717; p = 0,01), kdy ve dni bez TJ měly dívky o 37,4 min více SB. PA střední intenzity byla ve dnech s TJ zastoupena o 11,8 min více (F = 9,970; p = 0,002), stejně tak i PA vysoké intenzity (VPA) (F = 8,661; p = 0,004), které měly dívky více o 8,2 min. Objem SB byl významně vyšší na jaře v porovnání s podzimem (p = 0,03). PA nízké intenzity byla významně vyšší na podzim v porovnání se zimou (p < 0,001). Objem VPA byl vyšší v zimě (p = 0,03) a na jaře (p = 0,02) oproti podzimu. Závěry: V této studii bylo prokázáno, že objem SB a PA je odlišný ve dnech s TJ, bez TJ a také v rámci ročních období.

Background: Organized physical activity (PA) can significantly affect the volume of daily PA and sedentary behaviour (SB) related to the seasons at adolescent girls. Objectives: The main aim of this study is to compare the quantity of PA and SB at girls (aged 11-15) on the day with a training (TJ) and on the day without TJ in the context of seasonality. Methods: 27 girls participated in this study from a street dance group. PA and SB were monitored by the ActiGraph GT3X+. Data was measuring in the autumn (November), in the winter (March) and in the spring (May) of the 2017/2018 school year. The meteorological data was exporting from the station of Czech hydrometeorological institute. The results of the measurements were statistically processed in the IBM SPSS (SPSS, Chicago, IL). For descriptive statistic of PA and SB were using the arithmetic meanings, standard deviation and confidence interval. To determine the differences between the measured values of PA and SB, was using the analysis of variation of repeated measurements. Statistical significance was determined at the p=0.05 level. Results: Analysis of differences in the structure of physical behavior on the days with and without TJ showed significant values in SB (F=6,717; p=0,01), when girls had 37.4 min more SB on the day without TJ. Moderate intensity of PA was more represented on days with TJ by 11.8 min (F=9,970; p=0,002), as well as the vigorous intensity of physical activity (VPA) (F=8,661; p=0,004), which had girls had more about 8,2 min. The volume of SB, light intensity of physical activity (LIPA) and VPA varied significantly between seasons (p

BACKGROUND: Physical inactivity is a key contributor to the global burden of disease and disproportionately impacts the wellbeing of people experiencing mental illness. Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness. METHODS: The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Patients with a DSM or ICD mental illness diagnoses were recruited and completed the SIMPAQ on two occasions, one week apart. Participants wore an Actigraph accelerometer and completed brief cognitive and clinical assessments. RESULTS: Evidence of SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1010 participants. The SIMPAQ had good test-retest reliability. Correlations for moderate-vigorous physical activity was comparable to studies conducted in general population samples. Evidence of validity for the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had stronger evidence of validity. This alternative method is recommended for use in future studies employing the SIMPAQ. CONCLUSIONS: The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.

VÝCHODISKA: Preferování sedavého trávení volného času a nevhodné prostředí pro pohybovou aktivitu (PA) patří mezi hlavní příčiny snižování PA, poklesu úrovně tělesné zdatnosti a nepříznivého poměru příjmu a výdeje energie, což úzce souvisí s nárůstem nadváhy a obezity již u dětí mladšího školního věku. CÍLE: Cílem studie bylo zjistit vztah mezi pohlavím a celkovou denní PA dětí mladšího školního věku ve školních dnech. METODIKA: K řešení projektu bylo vybráno šest základních škol, které souhlasily s organizačně náročným výzkumem a byly charakterizovány stejným edukačním zaměřením a srovnatelným prostředím a podmínkami pro PA. Celkem na monitorování PA participovalo 85 děvčat a 84 chlapců. PA byla monitorována multifunkčním akcelerometrem ActiTrainer. Data byla zpracována prostřednictvím speciálního software Centra kinantropologického výzkumu ActiTrainer09. Ke statistickému zpracování dat byly použity základní statistické veličiny, jednofaktorová ANOVA a efekt size koefi cient ω2. VÝSLEDKY: Výsledky prokazují, že chlapci jsou pohybově aktivnější než děvčata v průběhu pobytu ve škole i v jeho jednotlivých částech, a to jak z hlediska počtu kroků, tak i z hlediska doby trvání střední až intenzivní PA. V celkové denní PA však nebyly zjištěny signifi kantní diference mezi chlapci a děvčaty. ZÁVĚRY: Studie potvrdila vyšší školní PA chlapců oproti děvčatům. Poznání zákonitostí v denní PA chlapců a děvčat vyžaduje hlubší studium jednotlivých segmentů školního dne, s využitím co nejobjektivnějších technik monitorování PA.

BACKGROUND: A preference of sedentary leisure time and an inap propriate environment for physical activity (PA) are some of the main reasons for the decline of PA, decreasing level of physical fi tness and an unfavorable balance between energy intake and expenditure. These determinants are closely related with the increase in overweight and obesity within primary school age children. AIM: The aim of this study was to determine the relationship between gender and total daily PA of primary school children on school days. METHODOLOGY: Six primary schools, which were characterized by the same focus and comparable educational environment and conditions for PA, were included in the research. A total of 85 girls and 8 4 boys participated in PA monitoring. The PA was monitored by the multifunction accelerometer ActiTrainer. The data was processed using the ActiTrainer09, the special software of the Cen- ter for Kinanthropology Research. The data was analyzed using basic statistical concepts, single-factor ANOVA and ω 2 effect size coefficient. RESULTS: The results showed that boys are more physically active than girls during their stay at school, both in terms of the step count, and duration of moderate-to-vigorous PA. There were no signifi cant diff erences between boys and girls in total daily PA. CONCLUSIONS: This study confi rms a higher PA of boys compared to girls during school. A knowledge of the patterns in the daily physical activity of boys and girls requires a deeper study of the various segments of the school day.

BACKGROUND: Lifestyle sport activities (e.g. parkour or skateboarding) are considered attractive and beneficial for a long-term commitment to physical activity (PA) and might be a great opportunity for adolescents who do not feel comfortable in an organized or competitive atmosphere. The purpose of the study was to assess whether participation in lifestyle activities is associated with moderate-to-vigorous physical activity (MVPA), out-of-school vigorous physical activity (VPA), and sedentary behaviour in adolescents aged 10-15 years, with major demographic variables (sex, age, socioeconomic status) being taken into account. METHODS: Data from a research project linked to the Health Behaviour in School-aged Children (HBSC) survey collected in 2017 in the Czech Republic was used. The sample consisted of 679 participants (303 of them girls) and was selected by quota sampling. Chi-square tests were used to assess differences in involvement in lifestyle activities according to sex, grade, and socioeconomic status. Ordinal and linear regression models were used to analyse the associations of participation in lifestyle activities and selected energy balance-related behaviours. RESULTS: Participation in lifestyle sport activities was significantly associated with a higher level of physical activity (MVPA and out-of-school VPA) after adjustment for sociodemographic factors, as was participation in organized sport. No significant associations were shown for sedentary behaviour. CONCLUSIONS: Adolescents participating in lifestyle sport activities report being more physically active and, in case of doing multiple such activities concurrently, also spending less time sitting than their peers not involved in lifestyle sport activities. As such, lifestyle sport activities seem to represent a feasible way of increasing overall PA level in adolescent population.

AIMS: This cross-sectional survey assessed and compared by gender the levels and correlates of achieving the international guidelines recommendations on five forms of physical activity (PA) (walking, moderate PA, vigorous PA, moderate or vigorous PA- MVPA, and muscle-strengthening PA). We examined the associations between achieving the international guidelines recommendations on five forms of PA and a variety of sociodemographic, health and academic performance variables. METHODS: Data was collected across nine Libyan universities (2008-2009, representative sample of 1,300 undergraduates). A self-administered questionnaire assessed frequency and duration of PA/week for each form of PA. Cut-offs for recommended guidelines were set according to the American Heart Association. RESULTS: About 43.7% of students achieved the guidelines for muscle strengthening PA, 20.7% for walking, 11.2% for vigorous PA, 28.5% for MVPA, and 4.8% for moderate PA (excluding walking). Binary logistic regression showed that except for walking, males were consistently associated with achieving the guidelines recommendations for all other forms of PA. Students with higher health awareness were more likely to achieve the guidelines for vigorous PA and muscle strengthening PA. Better academic performance was associated with higher levels of muscle strengthening PA. Students at institutions in the East of Libya were less likely to achieve the guidelines for walking, vigorous PA or muscle strengthening PA as compared to students from the North. Students from the West of Libya were also less likely to walk or to engage in moderate PA than their peers from the North. CONCLUSIONS: Overall, relatively low proportions of students achieved the recommended guidelines of PA. Female students were particularly at risk for low level of PA. Attention is required to national policies that promote active living, along with addressing the cultural, geographic and other barriers to engagement of young adult males and females in PA.
