This study documented recent citation metrics in 14 biomechanics journals from 2017 until 2021. Five recent metrics were extracted to report 2021 values, absolute and relative variability and slope over the five years. Mean usage were typical based on normalized metrics (0.6 to 1.1 for SJR3 & SNIP3) and IF5 and CS4 (2.7 & 3.5). Year-to-year absolute and relative variability were 0.11 - 0.48 and 12% - 21%, respectively. There was considerable variation of journal metrics in biomechanics journals supporting previous research journal metrics should not be reported to greater than one decimal place precision and meaningful differences across time need to be at least 0.3-0.5 or 30 percent.
