Hypothesis
Does a one-year exercise intervention program influence hip structure in pre-pubertal girls?
Conclusion
A one-year school-based exercise program for pre-pubertal girls does not influence the structure of the hip.
Supporting Evidence
- The intervention group did not show significant changes in hip structure compared to the control group.
- The study used dual X-ray absorptiometry (DXA) to evaluate hip structure.
- No correlation was found between the amount of exercise and changes in hip traits.
Takeaway
The study found that exercising more at school didn't make the girls' hips stronger or change their shape.
Methodology
The study involved 53 girls aged 7-9 in an exercise program and 50 control girls, with hip structure evaluated using DXA scans.
Potential Biases
Potential selection bias due to non-randomized school selection.
Limitations
The study could not assess the effects of different types of exercise or longer intervention periods.
Participant Demographics
Participants were healthy Caucasian girls aged 7-9 years.
