Isometric tongue strength was evaluated using the Iowa Oral Performance Instrument (<jats:styled-content style="fixed-case">IOPI</jats:styled-content>). <jats:styled-content style="fixed-case">JM</jats:styled-content> consisted of maximal countermovement jumps performed on a force plate to calculate weight‐corrected peak power and jump height. Total body dual‐energy X‐ray absorptiometry was used to assess appendicular lean mass (<jats:styled-content style="fixed-case">ALM</jats:styled-content>) to define sarcopenia based on commonly used <jats:styled-content style="fixed-case">ALM</jats:styled-content>/height<jats:sup>2</jats:sup> cutoffs.
