Influence of socioeconomic variables on physical activity and screen time of children and adolescents during the COVID‑19 lockdown in Germany: the MoMo study

The COVID‑19 (coronavirus disease 2019) pandemic created a multitude of natural experiments about the change of human behavior in a widely unfamiliar situation. Besides physical and mental health, physical activity (PA) and people’s movement behaviors were of particular interest to researchers all over the world. In a recent study, we found that among youth in Germany, sports activity declined, whereas recreational screen time and habitual activity increased during the first COVID‑19 lockdown. In the present study, we analyze the influence of the socioeconomic status and the housing situation on the changes in PA behavior and recreational screen-time before and during the first COVID‑19 lockdown among children and adolescents living in Germany. We found an alignment of PA behavior among youth from families with different socioeconomic backgrounds during the first lockdown and identified the housing situation to be a meaningful predictor of the increase in habitual activity. We conclude that restriction policies, communities, and in the last instance parents need to enable access to nonorganized PA to all children and adolescents every day and especially during potential future lockdowns.

“Do not deem the measures taken as violence...”: public charity and governance in Transbaikal during the political regime of the ataman G. Semenov

The object of this research is the regional charity and its transformation after February 1917, while the subject is the public charity in Transbaikal during the Civil War and political regime of the ataman G. Semenov. The research relies on the archival sources and periodical press materials. Using the systematic methodological principle, the topic is viewed in strong correlation with the events that unfolded in the society, taking into account structural, genetic, and functional relationships. The article is divided into parts, each of which reflects one of the facets of the articulated problem: disastrous fall in living standards of the population, household difficulties and psychological state peculiarities; crisis of the system of state care and collapse of the imperial system of organized public charity; public initiatives in the sphere of charity (forms, main recipients); “techniques” for encouraging charity used by the administration of the ataman G. Semenov. The conclusion is made that charitable activity overall during the political regime of the ataman G. Semenov retained. This was important, particularly in the conditions of declining living standards and growing number of destitute people, given that the circle of those eligible for receiving welfare has reduced, including for ideological reasons. The main recipients of public charity remained the orphans. Charity events for the own benefit, conducted by the educational institutions and ethnic diasporas, became a noticeable trend. The charity evenings for supporting the military, which in the early going appeared to be unregulated by Semenov’s administration, were prohibited. The authorities, interested in retaining public charity, often resorted to coercive measures fort its stimulation, including threats to habitual activity of the residents. The population was actively forced to donate for the army. The article reveals the methods of psychological pressure and coercion applied to population for participating in charity activities.

Tendons and ligaments of the Rangifer tarandus metapodial and hoof

Rangifer tarandus, the northern species including both reindeer and caribou, is a pillar of northern ecosystems and the lives of northern peoples. As the only domestic cervid, reindeer are important not only to the herders and hunters who presently interact with them, but also to zooarchaeologists and palaeontologists tracing their histories. Unfortunately, limited anatomical information on Rangifer tarandus muscles is available beyond descriptions of the large muscle groups. The lower limb and hoof in particular is poorly documented. This is problematic, as this important body part has the potential to be informative in zooarchaeological analyses of habitual activity, especially in regards to historical animal health, movement, and habitual activity. Better understanding of the hoof can additionally be useful to herders and veterinarians seeking to provide veterinary care for living animals. This study has used dissections and comparisons of the reindeer hoof with other domestic ungulates to document both the common and unique structures in Rangifer tarandus hooves, including the presence and attachment points of these structures. As these structures have proved unique, especially in regards to the dewclaw, it is important that other ungulates not be used exclusively in the analysis of Rangifer tarandus remains.

Once-Weekly Whole-Body Electromyostimulation Increases Strength, Stability and Body Composition in Amateur Golfers. A Randomized Controlled Study

Whole-body electromyostimulation (WB-EMS), an innovative training technology, is considered as a joint-friendly, highly customizable and particularly time-effective option for improving muscle strength and stability, body composition and pain relief. The aim of the present study was to determine the effect of 16 weeks of once-weekly WB-EMS on maximum isometric trunk (MITS), leg extensor strength (MILES), lean body mass (LBM) and body-fat content. A cohort of 54 male amateur golfers, 18 to 70 years old and largely representative for healthy adults, were randomly assigned to a WB-EMS (n = 27) or a control group (CG: n = 27). Bipolar low-frequency WB-EMS combined with low-intensity movements was conducted once per week for 20 min at the participants’ locations, while the CG maintained their habitual activity. The intention to treat analysis with multiple imputation was applied. After 16 weeks of once-weekly WB-EMS application with an attendance rate close to 100%, we observed significant WB-EMS effects on MITS (p < 0.001), MILES (p = 0.001), LBM (p = 0.034), but not body-fat content (p = 0.080) and low-back pain (LBP: p ≥ 0.078). In summary, the commercial setting of once-weekly WB-EMS application is effective to enhance stability, maximum strength, body composition and, to a lower extent, LBP in amateur golfers widely representative for a healthy male cohort.

Short-Term Physical Inactivity Induces Endothelial Dysfunction

ObjectiveThis study examined the effects of a short-term reduction in physical activity, and subsequent resumption, on metabolic profiles, body composition and cardiovascular (endothelial) function.DesignTwenty-eight habitually active (≥10,000 steps/day) participants (18 female, 10 male; age 32 ± 11 years; BMI 24.3 ± 2.5 kg/m2) were assessed at baseline, following 14 days of step-reduction and 14 days after resuming habitual activity.MethodsPhysical activity was monitored throughout (SenseWear Armband). Endothelial function (flow mediated dilation; FMD), cardiorespiratory fitness (V.⁢O2 peak) and body composition including liver fat (dual-energy x-ray absorptiometry and magnetic resonance spectroscopy) were determined at each assessment. Statistical analysis was performed using one-way within subject’s ANOVA; data presented as mean (95% CI).ResultsParticipants decreased their step count from baseline by 10,111 steps/day (8949, 11,274; P &lt; 0.001), increasing sedentary time by 103 min/day (29, 177; P &lt; 0.001). Following 14 days of step-reduction, endothelial function was reduced by a 1.8% (0.4, 3.3; P = 0.01) decrease in FMD. Following resumption of habitual activity, FMD increased by 1.4%, comparable to the baseline level 0.4% (–1.8, 2.6; P = 1.00). Total body fat, waist circumference, liver fat, whole body insulin sensitivity and cardiorespiratory fitness were all adversely affected by 14 days step-reduction (P &lt; 0.05) but returned to baseline levels following resumption of activity.ConclusionThis data shows for the first time that whilst a decline in endothelial function is observed following short-term physical inactivity, this is reversed on resumption of habitual activity. The findings highlight the need for public health interventions that focus on minimizing time spent in sedentary behavior.

Integration of Nationalistic and Religious Values in Islamic Education: Study in Integrated Islamic School

The education that integrates nationalistic and religious values expected to transform the student to be good citizens and God’ obedient servants. This research aims to explore two purposes: first, what is the purpose based on the integration of nationalistic and religious in learning in Integrated Islamic School; second, how is the teacher’s strategy in Integrated Islamic School in integrating nationalistic and religious in learning conducted. This research is qualitative research with case study approach. The data was taken from the interview of seven teachers in Integrated Islamic School of Yogyakarta Region from primary school to secondary school and documentation. The data collected was analyzed by interactively inductive data analysis technique of Miles and Huberman model consisting of data collection, data reduction, data display, and conclusion withdrawal. The finding of this research showed that; first, the integration of nationalistic and religious values was conducted based on the ideal Indonesian human concept that is the obedient human of Indonesian towards the state in which the main indicator is nationalism also the obedient human of Indonesian towards God in which the main indicator is religious soul. Second, the integration of nationalistic and religious values conducted through three main strategies, namely; integration in curriculum, co-curriculum, and extraculliculer; internalization of nationalistic and religious values; and habitual activity of nationalistic and religious values in the school culture. The finding of this research can be used as reference for teachers in implementing the strategy in integrating nationalistic and religious values to students.

Physical activity in children at risk of postthrombotic sequelae: a pilot randomized controlled trial

Increased physical activity is protective against worsening of postthrombotic syndrome (PTS) in adults. We assessed patient eligibility, consent, adherence, and retention rates in a pilot trial of prescribed physical activity following venous thromboembolism (VTE) in children. Secondary objectives were to describe the within-subject changes in PTS, quality of life, and coagulation biomarkers before and after the intervention in each group. We enrolled and randomized patients between 7 and 21 years of age to the physical activity group or the standard care (education-only) group in a 1:1 allocation ratio. The physical activity group wore a Fitbit for 4 weeks to determine habitual activity and then increased activity over an 8-week “active” period, followed by a 4-week “do-as-you-wish” period. Two hundred thirty-five children were diagnosed with VTE; 111 patients were screened, of whom 40 (36%) met study eligibility criteria. Of these, 23 (57%) consented to participate and were randomized (Fitbit,11; standard group, 12). The trial was of greater interest to overweight and obese children, as they comprised 83% of consented patients. Only 33% adhered to the activity prescription, and 65% (15/23) completed the trial. The PTS scores (P = .001) improved in the physical activity group compared with the education-only group. It is feasible to enroll and randomize pediatric VTE patients to a prescribed physical activity regimen 3 months following VTE. Metrics for adherence to enhanced physical activity and retention were not met. These results provide the rationale to explore low adherence and retention rates before moving forward with a larger trial of exercise training following VTE. This trial was registered at www.clinicaltrials.gov as #NCT03075761.
