Aims: To evaluate effects of a low energy diet, with or without strength training, on blood lipid profile in obese children.

Methods: Eighty two obese children were enrolled into a six week dietary programme, and were randomly allocated to a training group or a non-training group. The training group underwent regular exercise sessions with emphasis on strength training.

Results: Height increased significantly, with a non-significant reduction in body mass index. Fat free mass increased significantly in the training group. Serum total cholesterol was significantly reduced in both groups. The LDL:HDL ratio significantly decreased in the training group.

Conclusion: Results support the potentially beneficial effects of both diet and physical training. Further and longer term evaluation of such programmes is required.

Keywords: obesity; lipid; diet; strength training

Abbreviations: 10-RM, 10 repetition maximum; LDL, low density lipoprotein; HDL, high desity lipoprotein; TC, total cholesterol
