Abstract Study aim: The purpose of this study was to examine smartphone-using university students’ musculoskeletal system pain complaints, duration of smartphone and computer usage, participation in moderate-vigorous physical activities (MVPA), and prolonged sitting time.Material and methods: This study was conducted on Hitit University students (n = 387; 206 female, 181 male) in the province of Çorum. The International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Activity Assessment Ques­tionnaire (PAAQ) (sports/exercise activities section), and a personal information form prepared by the researchers were used as data collection tools. Descriptive statistics and the t-test were used to determine differences between groups. The Pearson chi-square test was used to examine the relationship between categorical variables.Results: It was observed that half of the participants with musculoskeletal system pain complaints (54.5%) feel the pain in all four areas (neck, shoulder, upper and lower back). There was no statistically significant relationship between physical activity intensity and pain complaint (p > 0.05). The students with musculoskeletal pain complaints spend more time on the smartphone and computer than students who do not have pain complaints (p < 0.05). During electronic device usage, the students who are in the low-intensity physical activity category spend more time sitting down than students in the moderate/vigorous intensity physical activity category (p < 0.05).Conclusions: In consequence, information can be provided about the importance of reducing sitting time during smartphone use and increasing the duration of moderate/vigorous-intensity physical activity (PA) so awareness can be raised on the issue among university students.

Background:Despite the plethora of research examining the physical activity-adiposity relation in youth, questions remain regarding the ideal intensity. Therefore, the purpose of this study was to explore the independent effects of physical activity intensity and incidental movement on total and trunk adiposity.Methods:The sample consisted of 1165 youth aged 8 to 17 years from the 2003−04 U.S. National Health and Nutrition Examination Survey. Physical activity (low, moderate, vigorous intensity) and incidental movement (activity level when not physically active) were measured using Actigraph accelerometers over 7 days. Total body and trunk fat were measured using dual-energy X-ray absorptiometry; age- and sex-specific percentile scores were calculated.Results:Bivariate analyses revealed an inverse relation between total, low, moderate and vigorous intensity physical activity with total body and trunk fat. After consideration of the total volume of physical activity in the multivariate analyses, moderate-to-vigorous intensity physical activity remained significantly related to total and trunk fat. Participants with the highest (top 12.5%) moderate-to-vigorous intensity activity values had total fat percentile scores that were 34 points lower than participants with the lowest (bottom 25%) values.Conclusion:These results are consistent with public health guidelines which recommend that children and youth participate in moderate-to-vigorous intensity physical activity.

Changes Over Time

This study examined two-year changes in patterns of activity and associations with body mass index (BMI) and waist circumference (WC) among adolescents. Inclinometers (activPAL) assessed sitting, sitting bouts, standing, stepping, and breaks from sitting. ActiGraph-accelerometers assessed sedentary time (SED), light-intensity physical activity (LIPA, stratified as low- and high-LIPA), and moderate-to-vigorous physical activity (MVPA). Anthropometric measures were objectively assessed at baseline and self-reported at follow-up. Data from 324 and 67 participants were obtained at baseline and follow-up, respectively. Multilevel mixed-effects linear regression models examined changes over time, and associations between baseline values and BMI and WC at follow-up. There were significant increases in BMI (0.6 kg/m2) and durations of prolonged sitting (26.4 min/day) and SED (52 min/day), and significant decreases in stepping (−19 min/day), LIPA (−33 min/day), low-LIPA (−26 min/day), high-LIPA (−6.3 min/day), MVPA (−19 min/day), and the number of breaks/day (−8). High baseline sitting time was associated (p = 0.086) with higher BMI at follow-up. There were no significant associations between baseline sitting, prolonged sitting, LIPA, or MVPA with WC. Although changes in daily activity patterns were not in a favourable direction, there were no clear associations with BMI or WC. Research with larger sample sizes and more time points is needed.

Background:Maternal physical activity declines across gestation, possibly due to changing perception of physical activity intensity. Our purpose was to a) determine whether rating of perceived exertion (RPE) during a treadmill exercise changes at a given energy expenditure, and b) identify the influence of prepregnancy physical activity behavior on this relationship.Methods:Fifty-one subjects were classified as either exercisers (N = 26) or sedentary (N = 25). Participants visited our laboratory at 20 and 32 weeks gestation and at 12 weeks postpartum. At each visit, women performed 5 minutes of moderate and vigorous treadmill exercise; speed was self-selected. Heart rate (HR), oxygen consumption (VO2), and RPE were measured during the last minute at each treadmill intensity.Results:At moderate intensity, postpartum VO2 was higher compared with 20- or 32-week VO2, but there was no difference for HR or RPE. For vigorous intensity, postpartum HR and VO2 were higher than at 32 weeks, but RPE was not different at any time points.Conclusions:RPE does not differ by pregnancy time point at either moderate or vigorous intensity. However, relative to energy cost, physical activity was perceived to be more difficult at 32 weeks compared with other time points. Pregnant women, then, may compensate for physiological changes during gestation by decreasing walking/running speeds.

AbstractPurpose We lack knowledge on whether the advice of “being physically active” should be the same for prevention and rehabilitation of low back pain (LBP). Sickness absence is a key outcome for LBP prevention and rehabilitation. We investigated the associations between physical activity and long-term sickness absence (LTSA) among employees with and without LBP. Methods Between 2011 and 2013, 925 Danish employees wore a Actigraph GTX3 accelerometer for 1–5 workdays to measure physical activity and reported LBP in past 7 days. Employees were followed for 4 years to determine their first register-based LTSA event (≥ 6 consecutive weeks). Results Among employees with LBP, increasing moderate-to-vigorous-intensity physical activity at work by 20 min and decreasing the remaining behaviors at work (ie., sitting, standing and light-intensity activity) by 20 min was associated with 38% (95% CI 17%; 63%) higher LTSA risk. Increasing light-intensity activity at work by 20 min and decreasing 20 min from the remaining behaviors was associated with 18% (95% CI 4%; 30%) lower risk. During leisure, increasing moderate-to-vigorous-intensity activity by 20 min or standing by 40 min was associated with 26% (95% CI 3%; 43%) lower and 37% (95% CI 0%; 87%) higher risk, respectively. Among employees without LBP, we found no such associations. Conclusions The physical activity advice ought to be different for LBP prevention and rehabilitation to reduce LTSA risk, and specified by domain and activity intensity. At work, employees with LBP should be advised to spend time on light-intensity physical activity and limit their time on moderate-to-vigorous-intensity physical activity. During leisure, employees should spend time on moderate-to-vigorous-intensity physical activity.

The Relationship

An improved method of physical activity accelerometer data processing, involving a wider frequency filter than the most commonly used ActiGraph filter, has been shown to better capture variations in physical activity intensity in a lab setting. The aim of the study was to investigate how this improved measure of physical activity affected the relationship with markers of cardiometabolic health. Accelerometer data and markers of cardiometabolic health from 725 adults from two samples, LIV 2013 and SCAPIS pilot, were analyzed. The accelerometer data was processed using both the original ActiGraph method with a low-pass cut-off at 1.6 Hz and the improved method with a low-pass cut-off at 10 Hz. The relationship between the physical activity intensity spectrum and a cardiometabolic health composite score was investigated using partial least squares regression. The strongest association between physical activity and cardiometabolic health was shifted towards higher intensities with the 10 Hz output compared to the ActiGraph method. In addition, the total explained variance was higher with the improved method. The 10 Hz output enables correctly measuring and interpreting high intensity physical activity and shows that physical activity at this intensity is stronger related to cardiometabolic health compared to the most commonly used ActiGraph method.

Introduction: To examine the validity and reliability of the Fitbit Charge HR (FCH), wrist-worn ActiGraph (AG) accelerometers were used for assessing the classification of physical activity (PA) into intensity categories in children. Methods: Forty-three children (n = 43) participated in the study. Each participant completed 3 min bouts of 12 PAs ranging from sedentary to vigorous intensity while simultaneously wearing FCH and AG on both hands, a Polar HR monitor, and a portable indirect calorimeter. Total time spent in different PA intensity levels measured by FCH and AG were compared to the indirect calorimetry. Results: The highest classification accuracy values of sedentary behavior was 81.1% for FCH. The highest classification (72.4%) of light intensity PA was observed with Crouter’s algorithm from the non-dominant wrist. Crouter’s algorithm also show the highest classification (81.8%) for assessing moderate to vigorous intensity PA compared to FCH (70.8%). Across the devices, a high degree of reliability was found in step measurements, ranging from an intra-class correlation (ICC) = 0.92 to an ICC = 0.94. The reliability of the AG and the FCH showed high agreement for each variable. Conclusion: The FCH shows better validity for estimating sedentary behavior and similar validity for assessing moderate to vigorous PA compared to the research-grade monitor. Across the devices, the reliability showed the strongest association.

Método: Participaron 20 alumnos de tercer grado de preescolar, 13 mujeres y 7 hombres, con una edad de 5.05±0.2 años, en un programa de educación física con intensidad moderada a vigorosa adaptado al modelo pedagógico CATCH (avance coordinado para la salud de los niños por sus siglas en inglés), las sesiones se llevaron a cabo 3 veces por semana, durante 12 semanas. La intensidad de la actividad física se determinó mediante el sistema para observar el tiempo de instrucción en la actividad física (SOFIT), antes y después del programa el desarrollo motor fue evaluado mediante el inventario de desarrollo Battelle valorando las variables de coordinación corporal, locomoción, motricidad fina y habilidad perceptiva, que determinan la puntuación de motricidad gruesa y fina. Resultados: La intensidad promedio de la actividad física moderada a vigorosa fue 65% del tiempo total de la clase de educación física, el análisis estadístico mediante el test t-Student para muestras relacionadas, reportó diferencias significativas en la puntuación de motricidad gruesa (p=0.00) y motricidad fina (p=0.00), antes y después de la intervención, el porcentaje de cambio resultó 25.5 Δ% y 11.3 Δ% respectivamente. Conclusión: a pesar que el programa CATCH reporta modestos resultados en variables asociadas a la obesidad en preescolares, su aplicación durante tres meses mostro una influencia positiva para la mejora del desarrollo motor en niños de edad preescolar. Abstract. Objective: To evaluate the effect of a physical education program with moderate-to-vigorous intensity on motor development in kindergarten students. Method: a total of 20 preschool students with average age of 5.05 ± 0.2 years old were involved (13 girls and 7 boys); they carried out a program of physical education at moderate-to-vigorous intensity, based on the pedagogical model of CATCH (Coordinated Approach to Child Health). The program was performed during 3 months, with 3 sessions per week. Intensity of physical activity was determined by the system for observing fitness instruction time (SOFIT), Motor development was determined using the education Battelle developmental inventory, assessing the variables of body coordination, locomotion, fine motor and perceptual ability, which determine the gross and fine motor score. Results: The average engagement time at moderate-to-vigorous physical activity intensity was 65% of the total time of the physical education class. The Student's t-test for related samples was run for the analysis. It reported significant differences in both gross (p=0.00) and fine motor scores (p=0.00), before and after intervention; the percentage of change was 25.5 Δ% and 11.3 Δ%, respectively. Conclusion: Although the CATCH program reports modest results in variables associated with obesity in preschoolers, its application for three months showed positive influence for the improvement of motor development in preschoolers.

Abstract Objectives Fear of falling (FoF) is common in older adults. Physical activity decreases as FoF increases. However, this association between physical activity and FoF may vary depending on activity intensity. The current study was performed to explore the associations between FoF and step count, light-intensity physical activity (LPA), and moderate/vigorous-intensity physical activity (MVPA) in community-dwelling older adults. Methods This cross-sectional observational study was held at a local community association center, with 242 older adults living independently in the community (mean age: 75.1 ± 5.4 years). FoF was defined using the Falls Efficacy Scale-International and categorized into three levels (low, moderate, and high). Physical activity was measured using a uniaxial accelerometer worn for 7 consecutive days, and by calculating daily step count, LPA, and MVPA, over this period. Results Step count and physical activity intensity showed significant linear trends across FoF severity (p &lt; .01, respectively). High FoF decreased step count by approximately 2,000 steps/day. Further, high FoF was significantly associated with short durations of both LPA and MVPA. In addition, moderate FoF was associated with decreased LPA duration, even after adjustment for confounding variables. Discussion Physical activity decreased concomitantly with a rise in FoF severity. Moreover, the association between physical activity and FoF differed by physical activity intensity level in community-dwelling older adults. Further studies are needed to investigate the causal relationship between FoF and objective physical activity in this population.
