Upper body force-velocity profiles to assess musculoskeletal performance are created using release speed (RS) of the barbell in a bench press throw (BPT). A more easily obtained variable is peak speed (PS) measured by a linear position transducer. We assessed the validity of predicting RS from measured PS. One hundred and seventy-eight throws from ten male participants age (mean ± SD) 27 ± 5 yrs, mass 88 ± 13 kg with minimum one year of resistance training performed the BPT with increasing loads on a Smith machine. Correlation revealed an exponential relationship of RS = 0.26e[superscript 0.9(PS)], (R[superscript 2] = 0.96, p < 0.05). We assessed predictive validity by comparing the measured RS of the barbell in each throw to the RS estimated by this formula. Bland-Altman analysis showed the 95% limit of agreement was 0.26 m·s[superscript -1] to 0.18 m·s[superscript -1], with a mean difference of 0.04 m·s[superscript -1] (2.92%), determining that PS may be used to estimate RS.
