Different Types

Changes of circulating free plasma DNA (cfDNA) are associated with different types of tissue injury, including those induced by intensive aerobic and anaerobic exercises. Observed changes are dependent from induced inflammation, and thus it may be a potential marker for athletic overtraining. We aimed to identify the response of cfDNA to different types of exercise, with association to exercise intensity as a potential marker of exercise load. Fifty volunteers (25 athletes and 25 physically active men) were assigned to the study and performed maximal aerobic (Bruce test) and anaerobic (Wingate Anaerobic Test) test. Blood samples for cfDNA analysis were collected at four time-points: before, 2–5 min after, 30 min after and 60 min after each type of maximal physical activity. The two-way ANOVA revealed a significant effect of group factor on serum cfDNA concentrations (32.15% higher concentration of cfDNA in the athletes). In turn the results of the post hoc test for the interaction of the repeated measures factor and the group showed that while the concentration of cfDNA decreased by 40.10% in the period from 30 min to 60 min after exercise in the control group, the concentration of cfDNA in the group of athletes remained at a similar level. Our analysis presents different responses depending on the intensity and duration of exercise. Our observations imply that formation of cfDNA is associated with response to physical activity but only during maximal effort.

Purpose: This study aimed to examine the increased benefits of a Self Determination Theory (SDT)-based motivational component on psychological needs’ fulfillment, self-determined motivation and Physical Activity (PA) of obese patients taking part in a rehabilitation program. Methods: Fourty-nine obese adults (mean age = 52 years, mean BMI = 38.25 kg/m2) attended a 3-week residential intervention. Patients in the Motivation group (n = 24) received a standard care plus SDT-based intervention (i.e., improved supervised PA sessions + a 1-hour motivational session). Patients in the Control group (n = 25) only benefited from standard care. Psychological needs and motivation were measured at baseline, at the end of the program and one month after. PA was measured at baseline and one month after the end of the program. Repeated measures ANOVAs were performed to compare the evolution of the variables between groups. Results: The results indicated that participants from both groups displayed significant changes in their perceived autonomy, relatedness, intrinsic motivation and integrated regulation between the beginning and the end of the program. Next, participants from both groups showed a decrease in perceived relatedness between the end of the program and one month after. Last, the participants from the Motivation group reported greater increase of their PA scores between the beginning of the program and one month after as compared to those in the Control group. Conclusions: Obesity interventions should integrate motivational components in order to promote behavior maintenance after programs have ended.

Abstract Background : Self-management of blood pressure is of great significance given the increasing incidence of hypertension and associated disabilities. With the increased use of mobile health in medicine, the present study evaluated the effect of the self-management application on patient adherence to hypertension treatment. Methods : This clinical trial was performed on 120 hypertensive patients who were provided with a mobile intervention for 8 weeks and followed-up to 24 th weeks. Data on the primary outcome (adherence to treatment) and secondary outcomes (adherence to the DASH diet, regular monitoring of blood pressure, and physical activity) were collected using a questionnaire and a mobile application, respectively. The inter-group change difference over time was analyzed using repeated measures ANOVA (General Linear Model). Results : The treatment adherence score increased by an average of 5.9 (95%CI: 5.0-6.7) in the intervention group compared to the control group. Scores of adherence to the low-fat and low-salt diet plans were 1.7 (95%CI: 1.3-2.1) and 1.5 (95%CI: 1.2-1.9), respectively. Moreover, moderate physical activity increased to 100.0 minutes (95%CI: 61.7-138.3) per week in the intervention group. Conclusion: The treatment and control of blood pressure require a multifaceted approach given its complexity and multifactorial nature. Considering the widespread use of smartphones , mhealth interventions can be effective in self-management and better patient adherence to treatments. Our results showed that this application can be used as a successful tool for hypertension self-management in patients attending public hospitals in developing countries.

The Impact

The aim of this research is to study the impact of physically active breaks, accompanied by video materials, on the level of pupils’ educational achievement and their attitudes toward physically active breaks during the teaching process in the classroom. The research lasted for two months, and the apposite sample consisted of a total of 38 pupils aged 10 to 11. The influence of physically active breaks on the educational achievement was estimated by the percentage of correct answers in the tasks of mathematics, while the Croatian version of the questionnaire Attitudes towards the Physical Activity Scale (APAS) was used for evaluating the attitudes toward physically active breaks with video materials. Differ ences between the initial and final measuring inside the same group were tested by the Student’s dependent sample t-test, while for differences between the experimental and control group the Student’s independent sample t-test was used. The obtained results showed that the ability to solve mathematical tasks in the experimental group has significantly improved when compared to the control one and that physically active breaks have a positive influence on the pupils’ attitudes toward physical activity. The implementation of physically active breaks into teaching has an impact on pupils’ productivity in the educational process, while at the same time their need for movement is fulfilled.

Physical activity is a promising intervention to restore cognitive function after prolonged sedentary periods. However, little is known about the effect of short physical activity bouts on cognition especially among individuals that are used to physical activity. Therefore, the goal of the present study was to assess the impact of a single ten-minute physical activity bout on the cognitive domain of visual attention compared to sedentary behavior in a population of physically active sport students. Using a randomized controlled design, 51 healthy and physically active sport students [mean age: 22.3 (SD: 2.0) years, 33.3% female] were allocated to one of the following interventions in the break of a two-hour study course: physical activity group (running for ten minutes) and sedentary control group. Visual attention was measured post-intervention using a modified trail making test. Pre-, post-, and 30 min after intervention, perceived attention, and affective states were measured. Between-group comparisons were used to analyze whether visual attention and/or changes in perceived attention or affective states differed between groups. The physical activity group showed significantly higher visual attention post-intervention compared with the sedentary control group, p = 0.003, d = 0.89. Perceived attention, p = 0.006, d = 0.87, and arousal, p < 0.001, d = 1.68, showed a significantly larger pre- and post-intervention increase in the physical activity group compared with the sedentary control group, which was not evident 30 min after intervention. A single ten-minute running intervention in study breaks might help to restore the basal visual attentional domain of cognition after prolonged sedentary periods more effectively compared with common sedentary behavior in breaks between study lessons.

Objective. This study investigated the acute residual effects induced by different frequencies of whole-body vibration (WBV) on postural control of elderly women. Design. Thirty physically active elderly women (67±5 years) were randomly divided into three groups: two experimental groups (high WBV frequency: 45 Hz and 4 mm amplitude, n=10; low WBV frequency: 30 Hz and 4 mm amplitude, n=10) and one control group (n=10), with no treatment. The participants were first subjected to stabilometry tests and were then guided through three sets of isometric partial squats for 60 s while the WBV stimulation was applied. The control group was subjected to the same conditions but without the WBV stimulation. The participants were again subjected to body balance tests immediately following the end of the intervention period and again at 8, 16, and 24 min. To measure body sway control, three 60 s tests were performed at 10 s intervals for each of the following experimental conditions: (1) eyes opened and (2) eyes closed. The following variables were investigated: the average velocity of the displacement of the centre of pressure in the anterior-posterior and medial-lateral planes as well as in the elliptical area. Results. A 3 (condition) × 5 (test) two-way repeated-measures ANOVA did not identify significant differences in the stabilometric variables, regardless of group, time, or experimental condition. Conclusions. The effect of WBV, regardless of the stimulation frequency, did not have a significant effect immediately after or up to 24 minutes after vibration cessation, on the variables involved in the control of postural stability in physically active elderly women.

Globally, more than half of school-aged children do not engage in the recommended 60 minutes of daily moderate to vigorous physical activity (MVPA). Given that developing sufficient fundamental motor skills (FMS) competence during early elementary school years is important for a child’s physical and cognitive development, the purpose of this study was to examine the effects of an 8-week FMS-based afterschool program on physical and cognitive health outcomes among elementary children. Participants were 31 K–2 students (19 girls, 12 boys; Mage = 6.65 ± 0.98) from three public elementary schools in the southwestern United States who were assigned to the intervention group (FMS-based afterschool program; n = 20) or the control group (traditional afterschool program; n = 11). A 2 × 2 repeated measures MANOVA showed significant changes in FMS competence and MVPA between the intervention and the control group over time. However, no significant changes were found in cognitive functioning. The 8-week FMS-based afterschool program showed significant improvements in FMS competence and MVPA, compared to a traditional afterschool program. This finding suggests that structured FMS-focused strategies (e.g., fun games and goal setting) can be a critical component when implementing a physical activity program to enhance children’s motor skills and physical activity behavior.

The study examines the effects of a preschool-based family-involving multicomponent intervention on children’s energy balance-related behaviors (EBRBs) such as food consumption, screen time and physical activity (PA), and self-regulation (SR) skills, and whether the intervention effects differed among children with low or high parental educational level (PEL) backgrounds. The Increased Health and Wellbeing in Preschools (DAGIS) intervention was conducted as a clustered randomized controlled trial, clustered at preschool level, over five months in 2017–2018. Altogether, 802 children aged 3–6 years in age participated. Parents reported children’s consumption of sugary everyday foods and beverages, sugary treats, fruits, and vegetables by a food frequency questionnaire, and screen time by a 7-day diary. Physical activity was assessed by a hip-worn accelerometer. Cognitive and emotional SR was reported in a questionnaire by parents. General linear mixed models with and without repeated measures were used as statistical methods. At follow-up, no differences were detected in EBRBs or SR skills between the intervention and control group, nor did differences emerge in children’s EBRBs between the intervention and the control groups when stratified by PEL. The improvement in cognitive SR skills among low PEL intervention children differed from low PEL control children, the significance being borderline. The DAGIS multicomponent intervention did not significantly affect children’s EBRBs or SR. Further sub-analyses and a comprehensive process evaluation may shed light on the non-significant findings.

Sedentary death syndrome (SeDS) is a major public health burden due to its causing multiple chronic diseases and millions of premature deaths each year. Despite the impact of physical inactivity, very little is known about the actual causes of physical inactivity-induced chronic diseases. It is important to study the mechanisms underlying molecular changes related to physical inactivity in order to better understand the scientific basis of individualized exercise prescription and the rapies for chronic diseases, and to support improved public health efforts by providing molecular proof that physical inactivity is an actual cause of chronic diseases. Physical activity has a genetic basis. A subpopulation of genes, which have functioned to support physical activity for survival through most of humankind's existence, require daily exercise to maintain long-term health and vitality. Type 2 diabetes (T2D) is an example of a SeDS condition, as it is almost entirely preventable with physical activity. To determine the true role of physical inactivity in the development and progression of T2D, information is presented which indicates that comparisons should be made to physically active controls, rather than sedentary controls, as this population is the healthiest. Use of sedentary subjects as the control group has led to potentially misleading interpretations. If physically active individuals were designated as the control group, a different interpretation would have been drawn. It is thought that there is no difference in GLUT4 concentration between T2D and sedentary groups. However, GLUT4 expression is higher in active controls than in sedentary and T2D groups. Therefore, to obtain causal mechanisms for SeDS in order to allow for scientifically based prevention and therapy strategies, physically active subjects must serve as the control group.

Meta Analyses

Objective: This review provides the first meta-analysis of the effects of physically active lessons on lesson-time and overall physical activity (PA), as well as health, cognition and educational outcomes. Design: Systematic review and meta-analysis. Six meta-analyses pooled effects on lesson-time PA, overall PA, in-class educational and overall educational outcomes, cognition and health outcomes. Meta-analyses were conducted using the metafor package in R. Risk of bias was assessed using the Cochrane tool for risk of bias. Data sources: PubMed, Embase, PsycINFO, ERIC and Web of Science, grey literature and reference lists were searched in December 2017 and April 2019. Studies eligibility criteria: Physically active lessons compared to a control group in a randomised or non-randomised design, within single component interventions in general school populations. Results: 42 studies (39 in preschool or elementary school settings, 27 randomised controlled trials) were eligible for inclusion in the systematic review and 37 of them were included across the six meta-analyses (n=12,663). Physically active lessons were found to produce large, significant increases in lesson-time PA (d=2.33; 95%CI 1.42, 3.25: k=16) and small, significant effects on overall PA (d= 0.32, 95%CI 0.18, 0.46: k=8). A large, significant effect was shown on lesson-time educational outcomes (d=0.81; 95%CI 0.47, 1.14: k=7) and a small, significant effect on overall educational outcomes (d=0.36, 95%CI [0.09, 0.63], k=25). No effects were seen on cognitive (k=3) or health outcomes (k=3). 25/42 studies had high risk of bias in at least 2 domains. Conclusion: In elementary and preschool settings, when physically active lessons were added into the curriculum they had a positive impact on both physical activity and educational outcomes. These findings support policy initiatives encouraging the incorporation of physically active lessons into teaching in elementary and preschool settings.
