In contrast, pubertal OB girls showed a statistically significantly higher %LO contribution at 25, 50, and 75 W stages compared with OW and NW as well as with OB pre‐pubertal girls.</p> </sec> <sec id="oby20611-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Our results demonstrate that entering puberty is a period associated with differentiation in substrate selection in obese girls. A higher %LO contribution may help girls to solicit more fat while performing submaximal exercise.</p> </sec> </abstract>
