XX(X): 000–000, 2026—The Army Fitness Test, implemented in 2025, assesses soldier readiness via 5 physically challenging events (3 repetition maximum deadlift, hand-release push-up, sprint-drag-carry, plank, and 2-mile run). Each event is graded by individuals with varying levels of experience, thus posing a threat to the reliability of the physical performance scores. The purpose of this study was to examine the inter-rater and intra-rater reliability of the two-minute hand-release push-up test to facilitate learning and improvement of assessing physical performance. Seventeen raters (5 female, 12 male) graded 10 hand-release push-up (HRPU) videos over 3 separate weeks (30 total videos, 60 total minutes). Each video contained a recording of a Cadet performing the two-minute HRPU test. Raters were required to provide a response after each repetition by stating “yes” for a proper repetition and “no” for an improper repetition. Researchers recorded all responses from raters in each of the 3 settings. Videos were randomized for each week of viewing with no rater viewing the videos in the same order. Using a logistic model, we were able to measure inter-rater and intra-rater reliability. Researchers calculated the intraclass correlation coefficient to evaluate overall reliability and agreement and Prevalence-Adjusted, Bias-Adjusted Kappa to further understand inter-rater and intra-rater reliability. Ultimately, we found that raters were not consistent as a group, with some showing significant fluctuations in their responses between tests. This finding is crucial because even small differences in scoring can negatively impact assessment on the HRPU event influencing a subjects's total score.
