The Influence of Lower Extremity Lean Mass on Landing Biomechanics During Prolonged Exercise.

ABSTRACT:

Context

  The extent to which lower extremity lean mass (LELM) relative to total body mass influences one's ability to maintain safe landing biomechanics during prolonged exercise when injury incidence increases is unknown.

Objectives

  To examine the influence of LELM on (1) pre-exercise lower extremity biomechanics and (2) changes in biomechanics during an intermittent exercise protocol (IEP) and (3) determine whether these relationships differ by sex. We hypothesized that less LELM would predict higher-risk baseline biomechanics and greater changes toward higher-risk biomechanics during the IEP.

Design

  Cohort study.

Setting

  Controlled laboratory.

Patients or other participants

  A total of 59 athletes (30 men: age = 20.3 ± 2.0 years, height = 1.79
