Popularization and Organization of Skipping Classes in Secondary Schools

Lessons of physical culture in modern secondary school include not only physical exercises and outdoor games, but also new sports, allowing to develop not only health technologies in a new format, but also health-saving education to make realistic. Students of secondary school № 25 in Sochi with pleasure in physical education lessons master fashionable fitness technology-skipping (jumping rope). Skipping rope as a sports attribute was known and loved by children of the Soviet era to increase motor activity in different amplitudes of movement, but then forgotten. Skipping rope allows you to develop coordination, develops endurance, helps to correct posture, develops flexibility of the body, it is also an excellent anaerobic exercise in order not to suffer from obesity. Research has shown that skipping is interesting for children of different ages in secondary schools, but is not popularized and promoted as a recreational, sports discipline that allows you to participate in competitions. Students of the Kuban State University of physical culture sports and tourism not only in the training processes themselves use skipping exercises, but also in the direction of biomechanics in design technologies promote skipping as a popular form of motor activity.

Actimetry-documented persistent Periodic Limb Movements during EEG-confirmed deep General Anesthesia: a case report.

Motor activity during general anesthesia (GA) without curarization is often interpreted as reflecting insufficient analgosedation. Here we present the case of an octogenarian scheduled for deep sclerectomy receiving opioid-sparing electroencephalography-(EEG)-guided anesthesia. Periodic Leg Movements (PLM) made their appearance with ongoing surgery while his raw EEG displayed a pattern of deep GA (burst suppression). To the best of our knowledge, this is the first description of actimetry-documented persisting PLM during EEG-monitored GA. Recognizing PLM in the context of GA is of importance for anesthesiologists, as increasing sedation may increase motor activity.

Some behavior features of a female Panthera pardus tulliana during pregnancy and at first parturitions

Ertuev MM, Semenov UA. 2019. Some behavior features of a female Panthera pardus tulliana during pregnancy and at first parturitions. Biodiversitas 20: 1333-1338. The present paper reports the results of the behavioral study of a female Panthera pardus tulliana during pregnancy, and before, during and after parturitions. The study was conducted in the Center of leopard recovery in the Caucasus, located in the mountain zone of the Sochi National Park, Russia. The behavior of Panthera was observed using surveillance cameras. During pregnancy, there is a significant shift in the level and ratio of hormones in the female's body. These internal changes can cause reorganization of the brain divisions which participate in the formation of the behavioral reaction, including female's behavior. We have shown that significant changes occur in the manifestation of individual behavior forms along with the increase of the pregnancy age and the intensification of fetal growth: a decrease in the level of anxiety and fear, and an increase in feed intake. At the end of pregnancy, the frequency of sleep and rest periods increases, but they are short-term. Before parturition, a female experiences painful sensations due to increase motor activity of the fetus, accumulation of toxins, possible hypoxia.

Telling apart motor noise from exploratory behaviour, in early development

Infant’s minutes long babbling bouts or energetic reaching for or mouthing of whatever they can get their hands on gives very much the impression of active exploration, a building block for early learning. But how can we tell active exploration from the activity of an immature motor system, attempting but failing to achieve goal directed behaviour? I will focus here on evidence that infants actively increase motor activity and variability when faced with opportunities to gather new information. I will discuss mechanisms generating movement variability, and suggests that, in the various forms it takes, from deliberate hypothesis testing to increasing environmental variability, it could be exploited for learning. However, understanding how infant exploratory behavior contributes to learning will require more in-depth investigations of both the nature of and the contextual modulation of behavioural variability.

PHYSICAL EXERCISES FOR PRE-SCHOOL CHILDREN WITH HOMEWORK AND PARENTS MOBILIZATION AROUND THESE TASKS

Introduction. Results presented in this article are part of an international project called Project of physical activity stimulation in a family (PPASF) held jointly with the Klaipėda University and LASE in Riga. We decided to check whether participation of children in preschool age in active classes in nursery school may be an impetus to change behavior in terms of physical activity of a family. For this purpose, a model was developed that included physical activity program conducted in the nursery school, with homework for the children to do together with their parents at home. The aim of the study was to examine the extent to which a child can persuade the parents to a common physical activity and whether sport and recreation for children with homework are a successful proposal to increase motor activity of the family. Material and methods. A diagnostic survey method was applied in the research, using a questionnaire technique. The survey questionnaire covered 38 families including 30 mothers and 8 fathers. Results and conclusions. Research has shown that children can become facilitators of physical activity in the family. The proposed model classes for children proved to be an accurate proposal, which is worth to implement the practice of teaching.

Canine small bowel motor patterns and contractions are not neurally regulated during enteric nutrient infusion

The aims of this study were to determine the effects of duodenal and jejunoileal nutrient infusions on small intestinal motor patterns and intestinal contractions in neurally intact and neurally isolated small bowel. Fifteen dogs were prepared with duodenal and jejunal infusion and manometry catheters and a diverting jejunal cannula. Ten of the dogs underwent in situ neural isolation of the jejunoileum. A mixed nutrient meal (0.5 kcal/ml) was infused into the duodenum or jejunum at 3 ml/min for 5 h. Control experiments involved infusion of a balanced salt solution. Manometric data collected on-line to a microcomputer were analyzed for direction, distance, and velocity of spread of single pressure waves (SPW) and clustered contractions. Isolated duodenal and jejunoileal nutrient infusions inhibited the fasting motor pattern in neurally intact and neurally isolated small bowel. Motor activity (motility index) increased slightly during nutrient infusion within groups, but there were few differences between groups. Neither neural isolation nor nutrient infusion had a consistent effect on spread of SPW or migration of clustered contractions. Isolated duodenal and jejunoileal nutrient infusions in the dog inhibit fasting motor patterns and increase motor activity slightly but have little effect on characteristics of individual and clustered contractions. Extrinsic innervation to the jejunoileum or intrinsic neural continuity of the jejunum with the duodenum had little effect on single or grouped contractions. Although the changes in motor activity demonstrated in this study appear small, alterations in intestinal transit and absorption may still occur and may be of importance physiologically.
