Cross-sectional study finds lean body weight predicts quadriceps torque in prepubescent and postpubescent athletes, aiding rehabilitation and return-to-play decisions.

Key Points

To establish normative and predictive strength values for major lower-extremity muscle groups based on anthropometric characteristics in youth athletes across pubertal stages.
Evaluated 60 healthy athletic prepubescent and postpubescent boys and girls using a Cybex II Dynamometer at an angular velocity of 60 deg/sec.
Measured anthropometric parameters and assessed their correlation with maximal torque development across quadriceps, hamstrings, ankle dorsiflexors, and plantar flexors.
Lean body weight showed the highest correlation with maximal torque force development among all anthropometric parameters evaluated.
Mean maximal quadriceps torque force equaled 70% of lean body weight in prepubescent children, 80% of lean body weight in postpubescent girls, and 90% of lean body weight in postpubescent boys.
Maximal torque force generated by the quadriceps correlated significantly with strength in the hamstrings, ankle dorsiflexors, and plantar flexors.
