Tracking of physical activity, physical inactivity, and health-related physical fitness in rural youth

This study examined the tracking of selected measures of physical activity, inactivity, and fitness in a cohort of rural youth. Students (N = 181, 54.7% female, 63.5% African American) completed test batteries during their fifth-(age = 10.7 +/- 0.7 years), sixth-, and seventh-grade years. The Previous Day Physical Activity Recall (PDPAR) was used to assess 30-min blocks of vigorous physical activity (VPA), moderate-to-vigorous physical activity (MVPA), TV watching and other sedentary activities, and estimated energy expenditure (EE). Fitness measures included the PWC 170 cycle ergometer test, strength tests, triceps skinfold thickness, and BMI. Intraclass correlation coefficients (ICCs) for VPA, MVPA, and after-school EE ranged from 0.63 to 0.78. ICCs ranged from 0.49 to 0.71 for measures of inactivity and from 0.78 to 0.82 for the fitness measures. These results indicate that measures of physical activity, inactivity, and physical fitness tend to track during the transition from elementary to middle school.

Motor competence and its effect on positive developmental trajectories of health

In 2008, Stodden and colleagues took a unique developmental approach toward addressing the potential role of motor competence in promoting positive or negative trajectories of physical activity, health-related fitness, and weight status. The conceptual model proposed synergistic relationships among physical activity, motor competence, perceived motor competence, health-related physical fitness, and obesity with associations hypothesized to strengthen over time. At the time the model was proposed, limited evidence was available to support or refute the model hypotheses. Over the past 6 years, the number of investigations exploring these relationships has increased significantly. Thus, it is an appropriate time to examine published data that directly or indirectly relate to specific pathways noted in the conceptual model. Evidence indicates that motor competence is positively associated with perceived competence and multiple aspects of health (i.e., physical activity, cardiorespiratory fitness, muscular strength, muscular endurance, and a healthy weight status). However, questions related to the increased strength of associations across time and antecedent/consequent mechanisms remain. An individual’s physical and psychological development is a complex and multifaceted process that synergistically evolves across time. Understanding the most salient factors that influence health and well-being and how relationships among these factors change across time is a critical need for future research in this area. This knowledge could aid in addressing the declining levels of physical activity and fitness along with the increasing rates of obesity across childhood and adolescence.

Cardiorespiratory fitness and cardiometabolic risk factors in schoolchildren from Colombia: The FUPRECOL Study

The objectives of this study are to investigate the association between cardiorespiratory fitness and cardiovascular risk factors in schoolchildren and to evaluate the degree of association between overall and abdominal adiposity and cardiorespiratory fitness. A total of 1,875 children and adolescents attending public schools in Bogota, Colombia (56.2% girls; age range of 9–17.9 years). A cardiovascular risk score (Z-score) was calculated and participants were divided into tertiles according to low and high levels of overall (sum of the skinfold thicknesses) and abdominal adiposity. Schoolchildren with a high level of overall adiposity demonstrated significant differences in seven of the 10 variables analyzed (i.e. systolic and diastolic blood pressure, triglycerides, triglycerides/HDL-c ratio, total cholesterol, glucose and cardiovascular risk score). Schoolchildren with high levels of both overall and abdominal adiposity and low cardiorespiratory fitness had the least favorable cardiovascular risk factors score. These findings may be relevant to health promotion in Colombian youth.

Validity and reliability of the international fItness scale (IFIS) in a population-based sample of schoolchildren in Bogota, Colombia: The FUPRECOL study

The International FItness Scale (IFIS) is a self-reported measure of physical fitness that could easily. This scale has been validated in children, adolescents, and young adults; however, it is unknown whether the IFIS represents a valid and reliable estimate of physical fitness in Latino-American youth population. In the present study we aimed to examine the validity and reliability of the IFIS on a population-based sample of schoolchildren in Bogota, Colombia. Participants were 1,875 Colombian youth (56.2% girls) aged 9 to 17.9 years old. We measured adiposity markers (body fat, waist-to-height ratio, skinfold thicknesses and BMI), blood pressure, lipids profile, fasting glucose, and physical fitness level (self reported and measured). Also, a validated cardiometabolic risk index was used. An age- and sex-matched sample of 229 Schoolchildren originally not included in the study sample fulfilled IFIS twice for reliability purposes. Our data suggest that both measured and self-reported overall fitness were associated inversely with adiposity indicators and a cardiometabolic risk score. Overall, schoolchildren who self-reported “good” and “very good” fitness had better measured fitness than those who reported “very poor” and “poor” fitness (all p<0.001). Test–retest reliability of IFIS items was also good, with an average weighted Kappa of 0.811. Therefore, our findings suggest that self-reported fitness, as assessed by IFIS, is a valid, reliable, and health-related measure, and it can be a good alternative for future use in large studies with Latin-schoolchildren from Colombia.

Importância da avaliação da aptidão física : avaliação da aptidão cardiorrespiratória no Virgin Active Oeiras

O presente relatório diz respeito às atividades realizadas no âmbito de um estágio no Health Club Virgin Active Oeiras (VAO), com incidência sobre a importância da avaliação da aptidão física aos utentes. Este estágio decorreu ao longo do 2º ano de Mestrado em Exercício e Saúde da Faculdade de Motricidade Humana. Para além de uma descrição e reflexão sobre os métodos e procedimentos adotados no decorrer do estágio, este relatório tem como objetivo principal explorar questões relacionadas com a metodologia de avaliação física aos utentes neste clube de saúde, com vista à sua otimização. Perante isto, foram estudados os meios disponíveis para a operacionalização de um protocolo de avaliação que englobasse todas as componentes da aptidão física segundo as recomendações atuais, incluindo a vertente cardiorrespiratória que não era usualmente avaliada no clube. De forma a atingir os objetivos pretendidos, o processo de sensibilização da direção do Clube foi realizado através da avaliação da aptidão cardiorrespiratória a 100 utentes iniciantes. Esta abordagem mostrou que 47% dos utentes iniciantes possuía uma aptidão cardiorrespiratória abaixo do razoável. Uma vez que esta análise era limitada, tendo em conta a elevada população que frequenta o clube, foram ainda abordados 150 utentes não iniciantes, através de uma campanha denominada “coração saudável”, na qual constou incluiu um “vale” para a realização de uma avaliação da aptidão cardiorrespiratória e um questionário. Este questionário refletiu que aproximadamente 70% dos utentes nunca tinha sido sujeito a uma prova de esforço já tendo frequentado outros clubes de saúde. Outras abordagens aos utentes foram realizadas durante este processo, nomeadamente, a promoção de atividades de cariz cardiorrespiratório e a disponibilização e instrução quanto ao uso do cardio-frequêncimetro. Este relatório refletiu a necessidade de um clube de saúde diferenciar-se não só pelas infraestruturas e atividades oferecidas, mas também pela informação e educação dos utentes relativamente à aptidão física relacionada com a saúde e ao impacto do exercício físico na qualidade de vida de quem o pratica.
