“…Diegene wat deelneem aan 'n gestruktureerde sportprogram neem meer deel aan gemiddelde tot energieke fisieke aktiwiteit. Dit het verskeie gesondheidsvoordele, waaronder gewigsverlies, minder vetsug, hoër beenmineraal-inhoud, 'n verbetering in aërobiese vermoë, groter spierkrag en uithouvermoë en ook 'n beter selfkonsep (Machado-Rodrigues et al 2012).…”

“…Mense se ekonomiese en maatskaplike status en opvoedingsvlak word uitgelig as faktore wat sportdeelname beïnvloed (Machado-Rodrigues et al 2012). Individue uit lande met 'n lae tot gemiddelde inkomstevlak het dikwels gebrekkige geriewe en 'n ontoereikende milieu vir die bevordering van deelname aan fisieke aktiwiteit (Machado-Rodrigues et al 2012).…”

With the increasing prevalence of emphasis on lifestyle-related wellness, the focus has been diverted from treatment and cure of disease to prevention and health promotion. Therefore, the area of wellness has received much attention and has been promoted with much enthusiasm, especially in the corporate industry. The present study delved into the area of overall physical wellness and explored its components and the influence of an active work environment on these components. This study adopted a cross-sectional, quantitative experimental design Undergraduate university students (n = 165) and 234 training recruits and law enforcement employees underwent several wellness assessments in a bid to compare overall physical wellness in sedentary and active work environments. The individual results were compared and scored into risk areas that were ultimately compounded to formulate an overall physical wellness indicator. It was found that the students were superior in some areas of wellness; the recruits, however, possessed a more pronounced state of overall physical wellness. This indicates that physical activity does contribute significantly to attaining a state of overall physical wellness and so reduces the risk of developing lifestyle related chronic conditions. The overall findings suggest that maintaining a healthy lifestyle through physical activity and health-promoting behaviour will result in a greater state of wellness. In this area of research a host of possibilities for future research are unfolding especially the overall wellness indicator.

“…O esporte é o modelo de atividade física que mais atrai a participação de crianças e adolescentes, ocupando papel de destaque no que tange ao dispêndio energético diário 1 . Assim, jovens atletas têm sido submetidos a elevados volumes de treinamento, em idades cada vez mais precoces, em virtude das altas exigências competitivas, o que provoca importantes alterações hemodinâmicas e eletrofisiológicas que podem acarretar aumento das dimensões cardíacas 2 .…”

RESUMOIntrodução: A morfologia do ventrículo esquerdo altera-se com o crescimento e desenvolvimento, durante a infância e adolescência. Contudo, são escassos os estudos comparativos entre não atletas e jovens atletas de elite. Objetivo: Analisar possíveis diferenças na morfologia do ventrículo esquerdo entre jovens atletas de elite e não atletas, do sexo masculino. Métodos: Trinta atletas de elite (15,4±0,6 anos; 68,0±11,3 kg; 175,2±7,5 cm) e 28 adolescentes saudáveis sem experiência com a prática esportiva (15,2±1,3 anos; 62,9± 3,8 kg; 168,8±7,7 cm) foram submetidos a medidas antropométricas (estatura, massa corporal e espessura de dobras cutâneas) e avaliações ecocardiográficas. Resultados: Diferenças estatisticamente significantes foram encontradas nos diâmetros telediastólico e telesistólico do ventrículo esquerdo, na espessura do septo interventricular em diástole, na espessura da parede posterior do ventrículo esquerdo, no diâmetro do átrio esquerdo e na relação entre o diâmetro do átrio esquerdo e o diâmetro da raiz da aorta, com os jovens atletas de elite apresentando valores superiores aos não atletas (P<0,01), mesmo após ajuste pela estatura. Correlações positivas e de moderada magnitude entre a massa do ventrículo esquerdo e a estatura foram encontradas em atletas (r=0,57) e não atletas (r=0,40). Conclusão: Os resultados do presente estudo sugerem que os valores superiores nas medidas da cavidade e de espessura da parede ventricular esquerda, encontrados no coração de jovens atletas de elite não podem ser explicados pela maior estatura, destacando a importância da exploração de modelos alométricos simples e multiplicativos que integrem medidas de maturação biológica em futuras investigações.

“…The relationship between PA and sedentary behaviors plays a fundamental role in energy expenditure [38]. Approximately 45% of the patients in our study watch TV and/or DVDs/Videos for two hours or more per day, with no difference between the groups, while 50% of the patients spend five or more hours on the computer and/or the internet per day, with weight-managed patients spending significantly less time on the computer and/or the internet per day compared with new patients.…”

Existing literature indicates that a weight-management program that includes diet modification, Physical Activity (PA) instructions and behavioral modification in weight reduction increases obese adolescents' participation in PA. However, the effect of such a program on obese Saudi adolescents is unknown. Objective: To examine the effects of a weight-management program in terms of decreasing Body Mass Index (BMI) and improving participation in PA in obese Saudi adolescents, and to establish whether differences exist between genders in response to a weight-management program. PA was measured by Arab Teens Life Style (ATLS) questionnaire for both groups. Results: A wide range of differences in PA and sedentary time are evident between new and weightmanaged patients and two genders. PA performance was significantly higher among the weightmanaged patients compared with new patients. Also, for boys there were no differences between both groups in PA performance. While, girls' PA was significantly higher among the girls in weightmanaged group compared with girls in new patients group. Weight-managed patients spend significantly less time on the computer and/or the Internet per day compared with new patients. After treatment, the mean BMI among the weight-managed patients slightly decreased. Conclusion: The study findings suggest that the weight-management program could be effective in treating Saudi obese adolescents due to its effect in BMI reduction and greater improvement in PA performance. The surprising result from this study, PA differences between the groups were because of the total PA of girls only, meaning that obesity treatment program can lower the percentage of obesity among women and increase their levels of physical activity.
