Age, male sex, hypertension, smoking, diabetes, dyslipidaemia, and obesity are considered as established risk factors for cardiovascular diseases. Several of these established cardiovascular risk factors are strongly influenced by lifestyle. Novel biomarkers from different mechanistic pathways have been associated with cardiovascular risk, but their clinical utility is still uncertain. The overall objective of the thesis was to evaluate the associations between certain lifestyle factors (physical activity and snuff use), biomarkers reflecting the haemostatic and the inflammatory systems and risk of a future first-ever myocardial infarction.  A prospective incident nested case-control study design was used with a total of 651 cases of myocardial infarction and 2238 matched controls from the population-based Northern Sweden Health and Disease Study.  The effects of commuting activity, occupational and leisure time physical activity on risk of myocardial infarction were studied. A clearly increased risk of myocardial infarction was found for car commuting compared to active commuting (walking, cycling or going by bus). High versus low leisure time physical activity was associated with decreased risk of myocardial infarction. Low occupational physical activity was associated with risk of myocardial infarction in men.  The risk of myocardial infarction or sudden cardiac death was studied in male snuff users compared to non-tobacco users. No increased risk was found for myocardial infarction or sudden cardiac death among snuff users without a previous history of smoking. However, for sudden cardiac death the study did not have statistical power to detect small differences in risk.  Plasma levels of haemostatic markers have previously shown to be associated with risk of myocardial infarction, but as haemostatic markers are also acute-phase reactants, it is not clear if their association with myocardial infarction is independent of inflammatory markers. In the present study, the haemostatic markers D-dimer, von Willebrand factor (VWF), tissue plasminogen activator (t-PA), and tissue plasminogen activator/plasminogen activator inhibitor-1 complex (t-PA/PAI-1 complex) were associated with risk of myocardial infarction after adjustment for established risk factors and the inflammatory markers C-reactive protein (CRP) and interleukin 6 (IL-6). Furthermore, the addition of eight haemostatic and inflammatory markers could improve the predictive ability for future myocardial infarction beyond that of a model utilizing only established risk factors.  Established risk factors and novel biomarkers were explored as potential mediators of the reduced risk of myocardial infarction related to active commuting. A combination of established risk factors, haemostatic and inflammatory markers appeared to explain a substantial proportion (40%) of the difference in risk for myocardial infarction between active commuters and car commuters. IL-6, t-PA, t-PA/PAI-1 complex, apo B/apo A-1 ratio, and BMI seemed to be the largest potential mediators when tested individually. In conclusion, regular physical activity such as active commuting is associated with reduced risk of a first-ever myocardial infarction. This effect could in part be mediated through a beneficial influence on haemostasis and inflammation, as well as a positive impact on established risk factors. Several haemostatic markers are associated with risk of myocardial infarction independent of established risk factors and inflammatory markers. The combination of haemostatic and inflammatory markers may enhance predictive ability beyond established risk factors. Our findings do not support the hypothesis that snuff use increases the risk of myocardial infarction.

This thesis deals with the topic: "Physical activity of persons employed with a focus on the teaching profession." In the theoretical part concepts related to history and the intensity of teaching, teachers and related mental stress health risks. are characterized. We also deal with the influence of physical activity on human health, and the ability to reduce the occurrence of various health risks. The aim of the thesis is to monitor physical activity among teachers in kindergarten, Basic school, including school with small classes and high school. It is assessed on the basis of a standardized questionnaire IPAQ-long and by monitoring using pedometers Yamax Digiwalker SW 700th The results found physical activity are compared with recommendations for physical activity and divided into categories according to the classification PA Tudor-Locke and Bassett.

Objectives: The purpose of this study was to examine what motivates physically active women to maintain their active lifestyle through exercise. Design: Cross sectional study. Methods: Physically active women (N=70) between the age of 19 and 84 were recruited at fitness centers and they completed the survey regarding their motives to maintain an active life style. The survey contained questions with several response options, and an open ended question where the women were asked to share their experiences and encouraging words for physically inactive women. The total number of distributed surveys was 90, of which 70 were complete. Results: The findings showed an association between a physically active life and good health. The majority of the participants claimed positive health benefits from training. The women who had a high exercise frequency also graded the exercise to be fun more often than women who were not training as frequently. The women also shared their own experiences of being active, and claimed that the physical, psychological and social benefits were great motivational factors to keep being active. Conclusions: The positive health benefits constituted the greatest motivation for maintaining a physically active life style.  The physically active women in this study showed that exercise has benefits; physical benefits such as pain relief or psychological benefits such as feeling good and happy, but also the social benefits of meeting new people.

Research has shown that social correlates of physical activity play an important role in individual participation in physical activity or sport, hence their link with associated health benefits. However, in spite of the health benefits associated with physical activity, many children do not meet the daily guidelines of being active for at least 30 minutes a day. This study investigated physical activity, health-related fitness and social correlates among 284 adolescents (111 boys and 173 girls) who are part of the on-going Physical Activity and Health Longitudinal Study (PAHLS). Height, weight, skinfold thickness (triceps, subscapular and calf skinfolds), waist and hip circumferences were measured through the standard procedures described by the International Standards of Advancement of Kinanthropometry (ISAK). Body mass index (BMI), waist-to-hip ratio (WHR) and percentage body fat (%BF) were used as measures of body composition. Health-related physical fitness (HRPF) was determined by measuring cardiorespiratory endurance, muscle strength and endurance, and flexibility using standardised tests according to the EUROFIT (1988) test protocol. The standardised International Physical Activity Questionnaire (IPAQ-Short form) and Social Support for Physical Activity questionnaire were used to gather information on participation in physical activity and social correlates for physical activity respectively. The results show that 29.6% of the adolescents were underweight and 26.4% overweight. Girls were significantly (p<0.05) fatter (%BF and BMI) and shorter than the boys. A significant gender difference (p<0.05) was also observed in WHR. Thirty four percent (34%) participated in low PA with 35% in high PA. Boys were significantly (z-4.52; p=0.000) more highly active compared to the girls. Boys measured significantly higher than girls (p<0.05) in SBJ, BAH, SUP, predicted 2max • V O . Adolescents’ participation in physical activity was affected by ‘lack of support by friends’, ‘encouragement by friends or family members’ and ‘lack of support during engagement in physical activity’. A significant difference (p<0.05) was found between boys and girls regarding ‘friends’ encouragement to do physical activity or sports’, ‘participation in physical activity or sports with friends’ and ‘friends’ confirmation that the participant is doing a good job at physical activity’. Positive correlations were found between Total Physical Activity (TPA) and all social correlates of PA, with a significant relationship between total physical activity (TPA) and ‘how often do your friends tell you that you are doing a good job at physical activity?’, and ‘has someone told you that you are doing well in physical activity?’ percentage body fat was negatively associated with social correlates of physical activity with a significant relationship in contrast with ‘friends’ encouragement that one is doing a good job at physical activity’. A significant positive correlation was observed between WC, WHR, SBJ, SUP, predicted 2max • V O and ‘friends’ encouragement in a typical week to do physical activity or sports’. Further significant positive correlations were found with WC for ‘encouragement by someone in a typical week to do physical activity or sports’; WHR, SBJ, BAH, SUP, predicted 2max • V O for ‘participation in physical activity or sports with friends’; SBJ, SUP, predicted 2max • V O for ‘friends’ encouragement that one is doing a good job at physical activity’; SBJ, SUP, predicted 2max • V O for ‘someone’s encouragement that one is doing a good job at physical activity’; BAH, SUP, predicted 2max • VO for ‘someone’s participation in sport with one’; SUP, predicted 2max • VO for ‘one’s encouragement to friends to participate in physical activity or sport’; SUP for ‘provision of transportation to physical activity or sport’; and predicted 2max • V O for ‘someone watching one participate in physical activity or sport’. SAR, on the other hand, was negatively associated with all social correlates for physical activity. It can be concluded that the adolescent boys in the study were underweight and significantly more active when compared to the relatively overweight and inactive girls. Boys also have higher health-related fitness and higher social correlates compared to the girls. Social correlates for physical activity were positively associated with participation in physical activity and healthrelated physical fitness variables. Thirty six percent (36%) of the participants indicated lack of transport as a negative factor for their participation in physical activity and sport. Based on these findings, urgent strategic public health intervention by all stakeholders dealing with adolescents, as well as more research studies in the area, is required. / PhD (Human Movement Science), North-West University, Potchefstroom Campus, 2015

Several researchers report that object control skills, health-related physical fitness and physical activity are not optimally developed in children. It is also evident from the literature that children, especially girls, are not active enough these days. These trends are disturbing as these are important factors that play a role in the health and sports development later in the child's life. Firstly, this dissertation attempts to examine the relationship between object control skills and health-related physical fitness in nine to ten-year old girls in the North-West Province of South Africa. Secondly, the relationship between object control skills and physical activity levels and patterns in nine to ten-year old girls in the North-West Province of South Africa was investigated. Data were collected by means of a stratified randomised sample of 408 girls with a mean age of 9,86 years (±0,42) who participated in the NW-CHILD study. The Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) (Bruininks & Bruininks, 2005) strength sub-test (standing long jump, push-ups, sit-ups, wall sit and V-up) was used to determine the girls’ strength, the Test of Gross Motor Development-2 (TGMD-2) (Ulrich, 2000) was used to determine the learners’ object control skills and the FITNESSGRAM (Meredith & Welk, 2008) was used to evaluate the girls’ cardiovascular endurance. The Children’s Leisure Activities Study Survey (CLASS) was used to evaluate the physical activity pattern of the girls. Stature, body mass and skinfolds (subscapular, triceps and calf) were measured according to standard kinantropometric protocols. The STATISTICA software package was used to analyse the data. Small but significant correlations were found between object control skills and strength, aerobic fitness and the body composition of the group. According to the healty fitness zone (HFZ) classification, 49.62% (n=198) of girls were categorised as being in the HFZ with regard to their BMI and 54.14% (n=216) in the HFZ with regards to the FAT%. This indicates that object control skills are influenced by factors that can contribute to the health of young girls. Participation in physical activities should therefore be increased. Appropriate development of object control skills (OC) and strength skills in girls is recommended to prevent delays in sports participation. Further investigation involved racial differences in activity performances. Ninety white and 318 black girls with a mean age of 9.86 years participated in this study. OC skills were assessed. Statistically (p≤0.001) and practically significant differences between the white and black girls were found, where the white girls participated more in ten of the moderate intensity physical activities than the black girls and the black girls participated more in three of these activities. Activities in which white girls mostly participated contributed significantly to higher moderate to high intensity. / MA (Kinderkinetics), North-West University, Potchefstroom Campus, 2015

Syftet med vår studie var att ge ett kunskapsbidrag till problemområdet motorik, utveckling och lärande med utgångspunkt från några pedagogers arbete med och förhållningssätt till fysiska aktiviteter och lärande i förskolan. Vi valde att genomföra en kvalitativ studie, där vi intervjuade sex verksamma förskollärare. Tidigare forskning har delade meningar om fysisk aktivitet och dess betydelse för barns lärande. Flera forskare konstaterar dock att det finns ett samband mellan motorik och lärande. Resultatet av studien visade att också verksamma pedagoger ser ett samband mellan motorik och lärande. Samtidigt visade studien andra faktorer som påverkar barns fysiska aktivitet och lärande, exempelvis miljön och sinnesorganen. Många av pedagogerna framhäver utomhusmiljön som en tillgång i arbetet med fysiska aktiviteter. Vid tillfällen som dessa, menar pedagogerna, tränas och stimuleras barns motoriska utveckling på ett naturligt sätt. Sammanfattningsvis upplever pedagogerna att motorik påverkar barn positivt; barnen blir rörligare, friskare och gladare.
