Effect of high intensity activity on children's aerobic power

Several studies in recent years have reported significant fitness improvements in children after exercise interventions, given sufficient training intensity, frequency and duration. However the knowledge of how fast children respond to exercise is limited and most research protocols are performed on cycle ergometers or other training devices using exercise programs are not applicable for practical purposes such as children’s sports programs or physical education classes. The aim of this study was to investigate the effect of high intensity aerobic activity in five weeks, two sessions per week, on children’s VO2peak. Additionally we wanted to test whether ten-year old boys were able to sustain intensity over 80 % of reart ratepeak (HRpeak) for a relative long period of time (up to 4 minutes), using aerobic games and play. Results from the present study showed a significant increase in VO2peak from 178.5 (± 12.6) ml x kg-0.67 x min-1 to188.4 (± 12.6) ml x kg-0.67 x min-1). Conclusion: Children can increase their VO2peak after five weeks of exercise with two high intensity sessions per week. This study also revealed that children can exercise near their HRpeak in time periods lasting up to four minutes

Seasonal variations in physical activity among Norwegian elementary school children in Arctic regions

The aim of this study was to measure seasonal variations in physical activity (PA) during Polar Nights (PN) and Polar Days (PD) among elementary school children in the Arctic regions of Norway. One hundred and seventy-eight schoolchildren from 1st, 3rd, 5th and 7th grade participated in the study. Physical activity was measured for seven consecutive days with an ActiGraph GT3X-BT accelerometer and is expressed as total PA incounts per minute (cpm) and moderate-to-vigorous activity (MVPA) (min∙day−1). During PN, 51% of boys and 33% of girls met the PA recommendations, whereas 36% of boys and 34% of girls met the recommendations during PD. Time spent doing MVPA did not differ between the two seasons (all p ≥ 0.073). Overall, the children accumulated 613 ±154 cpm during PN, which was lower than during PD 704 ± 269 cpm, p < 0.001). A larger proportion of boys than girls met the PA recommendations during PN compared with PD. Our findings did not show any clear seasonal variation for MVPA or total PA among children,except for some differences within sexes in different grades. This study indicates that interventions aimed at increasing PA should be implemented throughout the year in the Arctic regions

Food and chemical substances relevant for monitoring. Report from the Scientific Steering Committee of the Norwegian Scientific Committee for Food and Environment.

Source at https://vkm.no/At request from the Norwegian Food Safety Authority (NFSA), VKM has identified food groups and food items consumed by the Norwegian population that are relevant for monitoring regarding content of one or more undesirable chemical substances (Figure 1). Undesirable chemical substances were defined as chemical substances in food that may constitute a potential health risk. VKM has created a knowledge base (an Excel file) as a tool for planning and prioritising monitoring of foods and undesirable chemical substances. The substance groups included in the knowledge base are flavourings, food additives, metals and metalloids, natural toxins, persistent organic pollutants, process-induced contaminants, substances in food contact materials, substances in food supplements, and trace elements. More than 40 different substances were included

EuReCa ONE—27 Nations, ONE Europe, ONE Registry A prospective one month analysis of out-of-hospital cardiac arrest outcomes in 27 countries in Europe

AbstractIntroductionThe aim of the EuReCa ONE study was to determine the incidence, process, and outcome for out of hospital cardiac arrest (OHCA) throughout Europe.MethodsThis was an international, prospective, multi-centre one-month study. Patients who suffered an OHCA during October 2014 who were attended and/or treated by an Emergency Medical Service (EMS) were eligible for inclusion in the study. Data were extracted from national, regional or local registries.ResultsData on 10,682 confirmed OHCAs from 248 regions in 27 countries, covering an estimated population of 174 million. In 7146 (66%) cases, CPR was started by a bystander or by the EMS. The incidence of CPR attempts ranged from 19.0 to 104.0 per 100,000 population per year. 1735 had ROSC on arrival at hospital (25.2%), Overall, 662/6414 (10.3%) in all cases with CPR attempted survived for at least 30 days or to hospital discharge.ConclusionThe results of EuReCa ONE highlight that OHCA is still a major public health problem accounting for a substantial number of deaths in Europe.EuReCa ONE very clearly demonstrates marked differences in the processes for data collection and reported outcomes following OHCA all over Europe. Using these data and analyses, different countries, regions, systems, and concepts can benchmark themselves and may learn from each other to further improve survival following one of our major health care events

Motor competence and implications in primary school

The level of motor competence for six-year-old children are of special interest because at this age they have started at school, and they have to master new requirements. Ninety-four children were tested in fine- and gross- motor skills, by the Movement ABC test. Within the fifth percentile of the USA norms, 9.6 % of the children would have to be classified as to have motor problems, with 11.7% classified in the ‘borderline’ group. Sex difference were apparent in the section for manual dexterity, but in the sections balance and ball skills there were no significant differences, however, the girls were shown some better performance in balance skills. Finding from the present study shows boys falling into the motor impaired group to 12% and 6.8% for the girls. The cross-sectional data may provide a basis for recommendations for intervention programme for children with low motor competence in the primary school
