A modified functional reactive agility test (FRAT) provided total time (TT), decision time (DT), and movement time (MT) from each participant's shortest\u2010TT trial. Muscle health was characterized using skeletal muscle index (SMI) and handgrip strength, while functional performance was assessed separately using the five\u2010times sit\u2010to\u2010stand test (5STST). Between\u2010group differences were tested using one\u2010way or Welch analysis of variance as appropriate. Separate multivariable models were fitted for TT, DT, and MT, with multiple\u2010testing correction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Minimum\u2010TT trial outcomes did not differ among the four muscle\u2010health groups.

No other examined covariate remained significantly associated with reactive agility outcomes after multiple\u2010testing correction. Variance decomposition of TT showed that the MT variance term constituted the largest component of between\u2010participant variability (70.2%), compared with the DT variance (10.4%) and DT\u2013MT covariance (19.4%) terms.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Reactive agility did not differ significantly among muscle\u2010health groups, whereas 5STST performance was consistently associated with TT, DT, and MT.
