Notes: Data are mean ± SD. Bold indicates average ACFT scores that are below retention standards (failed event, < 60 points). RM, repetition maximum. Effect sizes were calculated as Hedges’ g according to Lakens [34]. *Cadets had the option to complete the leg tuck or plank, as such the sample sizes were different: Leg tuck, n = 45 and 3 for > 15th and < 15th, respectively; Plank, n = 6 and 6 for > 15th and < 15th, respectively.
