Physical activity and obesity in children

Abstract

Globally, obesity is affecting an increasing proportion of children. Physical activity plays an important role in the prevention of becoming overweight and obese in childhood and adolescence, and reducing the risk of obesity in adulthood. Puberty and the following adolescent period are acknowledged as particularly vulnerable times for the development of obesity due to sexual maturation and, in many individuals, a concomitant reduction in physical activity. In many Western settings, a large proportion of children and adolescents do not meet recommended physical activity guidelines and, typically, those who are more physically active have lower levels of body fat than those who are less active. Active behaviours have been displaced by more sedentary pursuits which have contributed to reductions in physical activity energy expenditure. Without appropriate activity engagement there is an increased likelihood that children will live less healthy lives than their parents. Owing to the high risk of overweight adolescents becoming obese adults, the engagement of children and adolescents in physical activity and sport is a fundamental goal of obesity prevention.

Análisis de los niveles de adiposidad y condición física en jóvenes escolares colombianos

“…Igualmente, en varias revisiones sistemáticas se ha señalado la necesidad de desarrollar políticas que fomenten el ejercicio físico, con el objetivo de aumentar la masa libre de grasa, mantener un peso corporal saludable y prevenir enfermedades en niños y jóvenes (18,19). A pesar de los avances en la divulgación de información y de las campañas y políticas públicas de prevención de la obesidad y de promoción de estilos de vida saludables y activos, en la sociedad actual se evidencia una elevada inactividad física, que ya se considera un problema de salud pública a escala global y que se perfila como el mayor del siglo XXI (20)(21)(22).…”

Park Characteristics Influences to Physical Activity among Overweight Adolescents

“…Recommended physical activity for young people aged 5-17 years includes play, games, sports, recreation and exercise (World Health Organization, 2010). Performing regular physical activity is a healthy way to decrease the risk of chronic and non-communicable diseases (Aniza and Fairuz, 2009;Sarwer and Dilks, 2012;Shukur et al, 2010; World Health Organization, 2010) and may reduce the risk of obesity (Hills et al, 2011). This possibility highlights the importance of efforts to increase and encourage physical activity among overweight adolescents so that they can reduce their weight and have a better quality of life in return.…”

“…This finding is consistent with the physical activity levels; the urban population had a lower level of physical activity (63.2%) than the rural population (67.2%). Based on this prevalence, it may appear that people in urban areas are more likely to be obese and are less likely to participate in physical activity.Although previous studies have suggested that the lifestyle transition and changes in the dietary patterns of Malaysians may contribute to the development of overweight and obesity (Pon et al, 2004), Hills et al (2011) revealed that low levels of physical activity may also be one of the factors. Recommended physical activity for young people aged 5-17 years includes play, games, sports, recreation and exercise (World Health Organization, 2010).…”

Efeito de dois modelos de treinamento físico na composição corporal, variáveis metabólicas e hepáticas de jovens obesos

“…Este distúrbio é considerado um fator de risco para diversas morbidades, como dislipidemias e as doenças cardiovasculares (HILLS; ANDERSEN; BYRNE, 2011;WHO, 2010). A prevalência da obesidade infantil é crescente e tende a se manter na idade adulta (OGDEN et al 2012;DUNCAN et al, 2011;LAMB et al, 2011).…”

“…Diante deste quadro, a utilização do treinamento físico enquanto estratégia de prevenção e tratamento a obesidade e EHNA durante a juventude tem sido largamente empregada (HILLS; ANDERSEN; BYRNE, 2011), com destaque ao treinamento concorrente. Este modelo de treinamento físico por combinar treinamento resistido e aeróbio em uma mesma sessão, estimula a oxidação lipídica, bem como, ganho de tônus e massa muscular (VASCONCELLOS et al, 2008).…”
