Velocity-based metrics like mean concentric velocity (MCV) at 1RM and load-velocity profiling enhance neuromuscular monitoring, yet the stability of parameters such as load-velocity slope (VL-Slope) and peak power position (PP-Position) over repeated tests remains uncertain. Thus, 14 resistance-trained male participants (age: 25.2 \u00b1 3.3 years; training experience: 2.1 \u00b1 2.0 years) performed five 1RM tests in the squat and bench press over a seven-week period. Strength and velocity parameters, including 1RM, MCV at 1RM, VL-Slope, and PP-Position, were assessed using an inertial measurement unit. A repeated-measures ANCOVA was conducted to analyze changes over time, with effect sizes quantified using partial eta squared (\u03b7p2) and standardized mean differences (SMD). No significant training-induced adaptations were observed for 1RM or MCV at 1RM across all testing sessions (p &gt; 0.05). VL-Slope and PP-Position remained stable, indicating no systematic changes over time. However, exercise-specific differences were found, with higher absolute loads and velocities in the squat compared to the bench press. Additionally, PP-Position was significantly higher in the squat, suggesting that peak power output occurs at a higher relative load for lower-body exercises. Repeated 1RM testing does not appear to induce relevant strength or velocity adaptations over time. Coaches and practitioners should consider exercise-specific differences in force-velocity characteristics when designing training programs and interpreting performance diagnostics.<\/jats:p>","DOI":"10.52082\/jssm.2025.303","type":"journal-article","created":{"date-parts":[[2025,4,17]],"date-time":"2025-04-17T03:38:45Z","timestamp":1744861125000},"page":"303-310","source":"Crossref","is-referenced-by-count":8,"title":["Effects of Repeated 1RM Testing on Strength, Velocity, and Load-Velocity Profiling: A Repeated Measurement Trial"],"prefix":"10.52082","author":[{"given":"Florian","family":"Micke","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduard","family":"Isenmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Geisler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steffen","family":"Held","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"29163","published-online":{"date-parts":[[2025,6,1]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Alcazar J., Rodriguez-Lopez C., Ara I., Alfaro-Acha A., Rodr\u00edguez-G\u00f3mez I., Navarro-Cruz R., Losa-Reyna J., Garcia-Garcia F.J., Alegre L.M.
