Following an independent review, the Army adopted the plank-hold (PLK), attempting to limit the influence of sex differences during the assessment. One component of the test, the leg-tuck (LTK) was found to disproportionately fail female soldiers. Army replaced their older physical fitness test with the Army Combat Fitness Test (ACFT) to replicate modern battlefield demands. T1 - The leg-tuck versus the plank-hold relative to the army combat fitness test: Interactions with body composition, strength and sex Independent t-tests compared sexes in all variables (p", ACFT standards were utilized for the LTK and PLK for all participants and a 10-minute rest was provided between tests. The following data were collected in one session: height body mass (BM), body fat (BF%) and muscle mass percentage (MM%) measured via bioelectrical impedance analysis combined grip strength (CGS) from both hands the LTK and the PLK. METHODS: 49 physically active civilian college students (28 males, 21 females) were recruited as a surrogate population for Army personnel in this study. PURPOSE: To determine relationships between the LTK, PLK, sex, body composition and abdominal and grip strength. However, research regarding performance, relationships, and the influence of sex on the LTK versus the PLK is limited. Independent t-tests compared sexes in all variables (pĪbstract = "In 2020 the U.S.
