“…These findings confirm the need for effective interventions to manage this global epidemic. Therefore, treatment and prevention of childhood obesity is a burning research question and many school children projects have used physical activity to treat or prevent the condition so far (1,3,21,22). However, there are few interventional studies of treatment of obesity in preschool children.…”

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...

“…Although strong evidence exists for the effectiveness of school-based PA interventions (1,5), studies rarely report their effect on fundamental movement skill (FMS) competency. This is a notable exclusion because evidence suggests that competency in a range of FMS may serve as protective factor against the decline in PA typically observed during adolescence (4).…”

“…Additionally, and according to several authors (Edouard et al, 2007;Aburto et al, 2011) children and youth of both genders show substantial improvements in muscle strength and aerobic capacity in response to different training protocols. This is consistent with our findings showing that a reduced period of concurrent training (10 weeks), during PE classes, seems to be enough to promote significant gains on youth physical fitness.…”
