Well-Being and Perceived Competence in School Children from 1 to 9 Class.

Motivational aspects in reading, math, science and physical education are often studied on whole samples and not grouped into different classes. In our study we wish to investigate cross-sectional data across classes. Our research question wishes to investigate what class differences are there in school subject-based well-being and perceived competence? A total of 378 Icelandic pupils in classes 1-9 did answer a survey with nine items, focusing on how are you feeling at school, how do you like and how are you doing in reading, math, science and physical education. There were 163 girls (43%), and 202 boys (53%) ranging from 6 to 15 years of age (M = 10.86, SD = 2.57). The findings, for the whole sample, indicate that girls tend to like reading more than boys do. Additionally, girls feel that they are better in science compared to boys, while boys like physical education more than girls. In terms of classes, multiple items, including reading, math and science, indicated class differences, where higher classes (i.e., eighth and ninth class) tend to have lower average scores in how much they liked a certain topic, and how competent they felt. It is also of great interest that the correlation between 'how do you like' and 'how are you doing' are 0.53, 0.71, 0.66 and 0.66 for reading, math, science and physical activity, respectively. Well-being and perceived competence in all subjects correlate with each other, and well-being at school. This shows the importance of seeing the school as a holistic system, where experiences related to individual subjects coincide with the overall experience (and vice versa). The results are discussed in relation to self-perception, motivation and practice.

Effect of exercise training for five years on all cause mortality in older adults-the Generation 100 study: randomised controlled trial.

OBJECTIVE: To evaluate the effect of five years of supervised exercise training compared with recommendations for physical activity on mortality in older adults (70-77 years). DESIGN: Randomised controlled trial. SETTING: General population of older adults in Trondheim, Norway. PARTICIPANTS: 1567 of 6966 individuals born between 1936 and 1942. INTERVENTION: Participants were randomised to two sessions weekly of high intensity interval training at about 90% of peak heart rate (HIIT, n=400), moderate intensity continuous training at about 70% of peak heart rate (MICT, n=387), or to follow the national guidelines for physical activity (n=780; control group); all for five years. MAIN OUTCOME MEASURE: All cause mortality. An exploratory hypothesis was that HIIT lowers mortality more than MICT. RESULTS: Mean age of the 1567 participants (790 women) was 72.8 (SD 2.1) years. Overall, 87.5% of participants reported to have overall good health, with 80% reporting medium or high physical activity levels at baseline. All cause mortality did not differ between the control group and combined MICT and HIIT group. When MICT and HIIT were analysed separately, with the control group as reference (observed mortality of 4.7%), an absolute risk reduction of 1.7 percentage points was observed after HIIT (hazard ratio 0.63, 95% confidence interval 0.33 to 1.20) and an absolute increased risk of 1.2 percentage points after MICT (1.24, 0.73 to 2.10). When HIIT was compared with MICT as reference group an absolute risk reduction of 2.9 percentage points was observed (0.51, 0.25 to 1.02) for all cause mortality. Control participants chose to perform more of their physical activity as HIIT than the physical activity undertaken by participants in the MICT group. This meant that the controls achieved an exercise dose at an intensity between the MICT and HIIT groups. CONCLUSION: This study suggests that combined MICT and HIIT has no effect on all cause mortality compared with recommended physical activity levels. However, we observed a lower all cause mortality trend after HIIT compared with controls and MICT. TRIAL REGISTRATION: ClinicalTrials.gov NCT01666340.
