Analyzed JPM included ground contact time, flight time, peak force during jumps and landings, jump height, modified reactive strength index, and net impulse. Additionally, the limb\u2010symmetry index was compared between groups along with the onset of seven lower limb muscles measured by surface electromyography.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Multivariate comparisons showed no significant differences in JPM or limb\u2010symmetry index between AT and CON participants. Solely, the AT group presented an earlier onset of tibialis anterior during RJs (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.005).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Discussion:<\/jats:bold>\n                    In conclusion, single\u2010leg jump testing in the targeted population indicated no generalized changes in overall functional capacity or onset of muscle activity, except in one jump for one specific muscle. However, the descriptively observed increased variability might suggest heterogeneous coping strategies in the presence of AT, highlighting the need for individualized assessments to detect performance deficits.\n
