[Cycloergometric exercise test in normal children: comparison of an Italian and a North American population].

The need for a more complete protocol for bicycle ergometer exercise testing in children in our country, induced the Authors to apply the F.W. James protocol to healthy Italian children and then compare the results with a study on a similar american sample population. A total of 102 children, 67 males and 35 females, age range 4.4 - 17 years (mean 10.3 yrs), were examined following the F.W. James protocol. The Authors report the anthropometric and ergometric data obtained, the comparison with James' results and the linear correlation coefficients. Normal reference data were obtained. There were no significant differences between the results obtained from the Italian and American groups, and the correlation coefficients were satisfactory. The results will enable us to benefit from a simple and complete protocol which can be applied to healthy and sick children alike in our country.
