LAS has been associated with reduced diaphragm contractility and altered breathing mechanics. The diaphragm and breathing mechanics are crucial for mitigating landing impact, which is typically impaired in individuals with LAS. Given this connection, innovative rehabilitation approaches that address dysfunctional breathing mechanics may be warranted. To date, no research has investigated associations between breathing mechanics and landing kinetics in adolescent female athletes with LAS.
