“…Thus, exercise training has been applied as the first choice for children who are overweight or obese, but not morbidly obese caused by underlying pathologies (16). Previous studies have reported that exercise training in children with obesity improves their body composition (10,28), cardiovascular function (4,7), and physical fitness (12,13,29). However, there are few studies of the effects of exercise training in obese children aged 5 years.…”

“…An alarm on the HR monitor was set up at ±10 beats of the target HR. Energy expenditure of an exercise session and overall program were estimated following the energy expenditure rate of various physical activities reported in our previous study (29). Main exercise of quick walking, slow running, jumping, rope skipping, semisquatting, and slow crawling have energy expenditure rates about 4-7 kcal/min, respectively.…”

Objectives:To explore the effects of exercise training on body composition, cardiovascular function, and physical fitness in 5-year-old obese and lean children. Methods: 42 obese and 62 lean children were randomly allocated into exercise and control groups separately. Body composition, cardiovascular function, and physical fitness were measured at baseline and the end of the intervention. The exercise groups participated in 10 weeks of supervised moderate intensity exercise training (at 50% of heart rate reserve), 50 training sessions in total. Results: The physical activity program was successfully completed and no sport injury occurred. Exercise training decreased BMI, waist circumference, body fat%, and fat mass; and slowed down the growth speed of body mass of both trained obese and lean children. Exercise training significantly decreased systolic blood pressure of obese children and decreased their heart rate responses during exercise. Trained obese children improved the performances of long jump, 10-m × 4 shuttle run, and 3-m balance beam walk; while trained lean children improved more items of physical fitness. Conclusions: 10 weeks of moderate intensity exercise training is an effective and safe treatment for children aged 5 years, either obese or with normal body mass.Keywords: childhood obesity, exercise, cardiovascular function, physical fitness Children obesity is a serious health problem (18,19).1 Negative impacts of obesity on health-related physical fitness, such as cardiovascular function, muscle strength, and flexibility, have been reported in children aged 3-6 years (17,20). The common treatments of obesity are diet, exercise, pharmacotherapy, and surgery (18,27). Diet is not suitable to young children as their bodies are at the fast growth period and sufficient nutrition must be guaranteed (26). Pharmacologic and surgical treatments should not be introduced carelessly in young children whose obesity is only caused by a positive energy balance from overeating and/or physical inactivity. Thus, exercise training has been applied as the first choice for children who are overweight or obese, but not morbidly obese caused by underlying pathologies (16). Previous studies have reported that exercise training in children with obesity improves their body composition (10,28), cardiovascular function (4,7), and physical fitness (12,13,29). However, there are few studies of the effects of exercise training in obese children aged 5 years. The purpose of the current study was to investigate the effects of exercise training in obese and lean children aged 5 years. Specifically, we evaluated the effects of obesity on cardiovascular function and physical fitness in children aged 5 years, by comparing baseline data between obese and lean children. The first hypothesis was that obesity would adversely affect cardiovascular function and physical fitness in children as young as 5 years old. Further, we studied the effects of 10 weeks of moderate intensity exercise training on body composition, cardiovascular funct...

RESUMOIntrodução: estudos epidemiológicos demonstram que o nível de atividade física (AF) está relacionado com a redução de diversas enfermidades. Por esta razão, esforços têm sido realizados para promover atividade física na população através de recomendações mínimas capazes de provocar benefícios à saúde. A avaliação do nível de AF requer instrumentos precisos e adequados. Objetivo: o objetivo deste trabalho foi realizar uma revisão dos métodos e instrumentos utilizados para medir e avaliar o nível de atividade física. Métodos: foi realizada consulta às bases de dados Medline/PubMed, SciELO, BioMed Central e Sport Discus, utilizando inicialmente os termos "physical activity assessment", "physical activity measure". Resultados: a partir desta busca, termos adjacentes e busca por autores foram efetuadas. Medir a AF é uma tarefa complexa, visto que ela pode ocorrer em diversos contextos. Os métodos de medida da AF podem ser classificados em objetivos (água duplamente marcada, calorimetria, observação direta, monitores cardíacos e sensores de movimentos) e subjetivos (questionários e diários). Conclusão: a variedade de métodos utilizados para medir AF resulta em um campo vasto de difícil equivalência e comparações. Atualmente, nenhum dos métodos pode ser considerado suficiente a ponto de descartar os demais e, por isso, a combinação de mais de um método pode resultar em uma melhor avaliação da AF.Palavras-chave: atividade física; avaliação; métodos de medida. ABSTRACTIntroduction: Epidemiological studies have demonstrated a relationship between physical activity (PA) level and some diseases. Therefore, efforts have been done to promote PA in the population through minimum recommendations able to promote health benefits. The assessment of PA level requires accurate and appropriate instruments. Purpose: The aim of this study was to review methods and instruments used to measure and assess the PA level. Methods: It was conducted a search in medline/pubmed, scielo.org, biomed central and sport discus using the following terms "physical activity assessment", "physical activity measure". After this initial search, adjacent terms and authors searches were made. PA measure is complex whereas it can occur in different contexts. Results: The methods for measuring physical activity are classified in objectives (doubly labeled water, calorimetry, direct observation, heart monitors and motion sensors) and subjectives (questionnaires and diaries). Conclusion: The variety of methods used to measure PA results in a difficult field of comparisons. Currently, none of the methods can be considered enough in order to discard others, therefore, combination of more than one method should result in a better assessment of PA.
