Differences in Hip and Knee Running Moments across Female Pubertal Development

AbstractPurposeTo investigate whether knee and hip running moments differ across stages of female pubertal development.MethodsThis was a cross sectional study comparing the barefoot running moments of 91 pre-pubertal (n=31, Tanner stage I), early/mid-pubertal (n=30, Tanner stage II-III) and late/post-pubertal (n=30, Tanner stage IV-V) girls. External peak moments for knee abduction (KAbM), knee adduction (KAM), knee flexion (KFM) and knee internal rotation (KIRM) were analyzed. Secondary measures of hip adduction moment (HAM) at time of peak KAbM and hip flexion moment (HFM) at time of peak KFM were also derived. Between-group differences were analyzed using a series of one-way ANOVAs and ANCOVAs.ResultsAt the knee, the late/post-pubertal girls displayed a higher peak KFM and KAM compared to the pre-pubertal group (p0.05). At the hip, both the late/post- (p=0.03) and early/mid-pubertal girls (p= 0.039) ran with a lower HAM at time of peak KAbM than the pre-pubertal girls. The HFM at time of peak KFM in late/post-pubertal girls was also significantly lower than both the early/mid- and pre-pubertal girls. (p0.05). At the hip, both the late/post- (p=0.03) and early/mid-pubertal girls (p= 0.039) ran with a lower HAM at time of peak KAbM than the pre-pubertal girls. The HFM at time of peak KFM in late/post-pubertal girls was also significantly lower than both the early/mid- and pre-pubertal girls. (p
