The objective of the paper was to analyze cardiopulmonary data and functional capacity in healthy children who have undergone ergospirometry. A systematic meta-analysis review of ergospirometry in children was performed based on reports indexed in PubMed, Bireme, and Embase. End points were age, sex, body mass index, maturation evaluation, the type of ergometer used for ergospirometry, and cardiopulmonary related values (peak heart rate and peak oxygen consumption [VO2]). Twenty articles were selected, which included 3,808 children, averaging 9.1years of age. A treadmill was used in 55% of the trials, and a cycle ergometer in the other 45% studies included in this analysis. The following statistically significant results were found: on subgroup analysis, peak VO2 values in boys on the treadmill was 20% higher than peak VO2 values in girls on the cycle ergometer; peak VO2 values in boys on the treadmill were 18% greater than that for girls on the same ergometer. BMI was inversely correlated with peak VO2 in the total analysis, and in female subjects on cycle ergometers. Peak heart rate during the ergospirometrical test was 5.6 BPM higher than the estimated 95% maximum heart rate. Most of the ergospirometrical parameters had not been reported in the original trials analyzed here. We conclude that peak VO2 value for pre-pubertal children are circa 18% higher in boys vs. girls and overall higher in treadmill vs. cycle ergometers.
