Study Objective Assess the effect of physical exercise on a sub‐sample of the subjects weight Statement of Methods The study used a cross‐sectional descriptive comparative design. A Multi‐stage stratified random sampling technique was used in selecting 10 schools out of 54 and 2000 children out of 13,981 that were used for the study. Anthropometric measurements (weight, height and triceps) were obtained in the subjects to determine obesity. High‐energy physical exercise was carried out for a period of two months on a sub‐sample of thirty obese children and the data were compared with a control group who did not receive any exercise.

Their initial mean weight was 59.06kg and final mean weight was 49.23kg, with a mean weight loss of 9.52kg. The total time spent by the male children was significantly (p<0.05) longer, relative to the female on the exercise. Table 1 shows the influence of exercise on weight loss of children, n=30 and table 2 shows the BMI classification of children after the exercise. Table 2 shows the classification of BMI by sex of the children after the exercise .Classification of BMI Intervention Group Control. GroupMale. Female. Total Male. Female. TotalF. %. F. %. F. % F. %.

This reduction explains that in addition to dietary modification, there is need to include physical exercise in the life style of children.
