Research has clearly shown that all individuals will benefit from regular physical activity. Unfortunately, young adults including college and university students are not physically active on a regular basis worldwide. In the developing world particularly in Sub- Saharan Africa, physical inactivity along with tobacco use, poor diet and nutrition are increasingly parts of today&rsquo / s lifestyle. Physical activity declines with age and the most important decline appear to be during the transition period from high school to university and during university years. The aim of this study was to assess the level of physical activity, to investigate the perceived constraints to physical activity and to determine whether socio-demographic characteristic have an influence on participation in physical activity and perceived constraints to physical activity among paramedical institutions students in Uganda. A cross-sectional study with descriptive quantitative design was conducted. Four hundred (400) paramedical institution students were selected using a stratified random sampling technique. A self-administered questionnaire adopted from the literature was used to collect the data. A response rate of 90% was obtained. Descriptive and inferential statistics using the statistical package for social sciences were used to analyze the data. The relationships and associations between different variables were determined by carrying out significant tests using chi-square tests. Alpha level was set at 0.05. The mean age of the sample was 22.44 years (SD = 2.03). Males constituted 73.9% and females constituted 26.1% of the sample. Students from eight (8) health professional courses participated in the study. Over half (59%) of participants were classified as physically active and 41% were classified as inactive or sedentary. For male participants, lack of the right equipment to exercise and wanting to do other things in their free time were perceived as the major constraints to physical activity. For female participants, lack of motivation and tiredness after exercise were perceived as the major constraints to physical activity. The findings of this study demonstrate that there is an influence of socio-demographic characteristics such as gender, year of the study and different departments/schools on participation in physical activity and perceived constraints to physical activity. They also indicate the need of health promotion intervention aiming at promoting physical activity among paramedical institution students in Uganda.

<p>Associated with physical inactivity and obesity are numerous other health risks which have become a major health concern. A steady decrease in the levels of physical activity during childhood and adolescents have been noted in various parts of the world. The picture of low physical activity levels in developed countries is no different in developing countries. Children spend the majority of their day at school therefore a school setting is ideal to conduct physical activity intervention studies The primary aim of this study was to measure the effect of an intervention programme on the physical activity participation levels among school going children and adolescents. The study was carried out at an urban independent Catholic school. The sample, which was conveniently selected, which included 100 learners from grade 5 to 7 with parental consent. A quantitative approach using a quasi-experimental design was used in this study. Baseline data included levels of physical activity participation, Body Mass Index (BMI), hip-waist ratio, and socio-demographic variables. Physical activity was assessed with the Modifiable Activity Questionnaire for Adolescents. The Promoting Lifestyle activity for Youth (PLAY) programme was implemented at the school. This process-oriented programme shifts the focus from fitness toward regular participation in daily physical activity, and it is not intended to replace a comprehensive physical education programme.</p>

Self-report recall questions are commonly used to measure physical activity, energy expenditure (EE) and time use in children and adolescents. However, self-report questionnaires show low to moderate validity, mainly due to inaccuracies in recalling activity in terms of duration and intensity. Aside from recall errors, inaccuracies in estimating energy expenditure from self-report questionnaires are compounded by a lack of data on the energy cost of everyday activities in children and adolescents. This thesis describes the development of the Multimedia Activity Recall for Children and Adolescents (MARCA), a use-of-time instrument designed to address both the limitations of self-report recall questionnaires in children, and the lack of energy cost data in children. / The thesis begins by investigating the energy cost of everyday activities in children and adolescents. An extensive literature search was undertaken to identify as many studies as possible where the energy cost of child and adolescent everyday activities were measured. Data were available from 52 studies totalling 5982 measures made on 43 activities. The data collated in the literature search was used to identify significant gaps in the literature and evaluate existing techniques of assigning energy cost values to child and adolescent activities when measured values are not available. The results suggest that using adult METs is the most accurate technique to assign energy cost values when child-specific measures are not available. / After identifying areas of missing energy cost data, the energy cost of three types of child and adolescent activities were measured: playing video centre games; performing household chores; and “new locomotions”, i.e. riding non-motorised scooters and rollerblading. A total of 131 measures were undertaken on 11-13 year old children using indirect calorimetry. Energy costs ranged from 1.3 to 6.4 METs for video centre games; 1.9 to 3.6 METs for household chores; and 6.5 to 6.6 for the new locomotions. / Next, the development, validity and reliability of the MARCA are discussed. The MARCA is described in terms of its three components: the 1-d recall; the compendium of child-specific energy costs and the analytical module. In particular, the advantages of the multimedia features of the MARCA over traditional pen and paper questionnaires are highlighted. The MARCA was then validated by comparing accelerometer counts with MARC recall data collected on a sample of sixty six 10-13 year olds. The MARCA showed validity comparable to other self-report instruments with Spearman coeffiecients ranging from 0.88 to 0.94. Finally, the thesis demonstrates the unique analytical capabilities of the MARCA via a variety of analyses conducted on the MARCA self-report recall profiles of 1429 children and adolescents aged 9 to 15 years. / Thesis (PhDHumanMovement)--University of South Australia, 2005.

Philosophiae Doctor - PhD / For many decades, the World Health Organisation had highlighted the growing importance of chronic non-communicable diseases in developed and developing countries, with an increase in lifestyle-related diseases. Physical inactivity has been identified as one of the risk factors, in addition to other leading risk factors like diet, and the use of tobacco and alcohol, contributing to the occurrence of non-communicable diseases like cardiovascular diseases, cancers, obesity and type 2 diabetes mellitus. Based on the researcher's observations while living in Belhar community for more then ten years, it was hypothesized that the level of physical inactivity among adolescents could become a public health problem in the future if not addressed immediately. / South Africa

Physical inactivity is recognised as a major risk factor for non-communicable diseases such as hypertension, cardiovascular disease, diabetes and cancer. Current recommendations for participation in physical activity are 30 minutes or more of moderate-intensity physical activity on most, but preferably all days of the week. The aim of the study was to determine the effect of a physical activity programme on weight, blood pressure, body mass index and body fat classification among high school learners through a short-term physical activity intervention programme.
