Exercise training in obese children and adolescents : current concepts. -- Posted by Sweet Zombie Jesus! on 06-02-05 10:11
Childhood obesity has reached epidemic proportions worldwide and is
associated with increased cardiovascular mortality and morbidity in
adult life. The increase in fat mass in children and adolescents has
occurred concomitantly with a decline in reported time for exercise.
Evidence suggests that non-physically active children are more likely
to become non-physically active adults and that encouraging the
development of physical activity habits in children helps establish
patterns that continue into adulthood. Dietary treatment of obesity is
relatively ineffective in adults and it has been suggested that
prevention of obesity in childhood and adolescence should emphasise
increased physical activity rather than diet because of fears relating
to the adverse effects of inappropriate eating patterns. Despite this,
there are very few randomised controlled studies investigating the
efficacy of exercise training in obese children or adolescents and many
of the extant studies have been poorly controlled and have not
specifically stratified the independent effect of exercise versus
dietary modification.
This review focuses on the well designed controlled trials that have
evaluated the effect of exercise training in obese children and
adolescents on body composition, haemodynamic and metabolic variables,
cardiovascular fitness, muscular strength and vascular function. These
studies indicate that, although exercise training does not consistently
decrease bodyweight or body mass index, it is associated with
beneficial changes in fat and lean body mass, emphasising the
importance of comprehensive assessment of body composition in future
exercise-training studies.
Exercise training improves cardiovascular fitness and muscular
strength; however, it seems to have little effect on blood lipid
profile or blood pressure in obese young people. Importantly, recent
studies have demonstrated that exercise training improves vascular
endothelial function, an important surrogate measure that may predict
future atherosclerotic risk in obese children and adolescents.
Given that improvement in vascular function in these training studies
occurred in the absence of changes in lipid fractions, haemodynamic
variables or glucose metabolism, exercise appears to have a direct
beneficial effect on the vasculature, in addition to its putative
benefits through risk-factor modification.
