Physical training of 9- to 10-year-old children with obesity to lactate threshold intensity

Pediatr Exerc Sci. 2010 Aug;22(3):477-85. doi: 10.1123/pes.22.3.477.


The purpose of this study was to apply the lactate threshold concept to develop a more evidence-informed exercise program for obese children. 60 obese children (26 girls and 34 boys, age: 9-10 years, BMI: 25.4 +/- 2.2kg/m(2)) were recruited and half of them were randomly selected to be trained for eight weeks with a controlled exercise intensity at lactate threshold. The trained children achieved significant improvements on their body composition and functional capacity compared with the control group. The findings suggested that the training program with intensity at lactate threshold is effective and safe for 9-10 year old children with obesity.
