| description | Background: The prediction of one repetition-maximum (1RM) performance from specific tests is highly relevant for the monitoring of training in weightlifting. Therefore, this study aimed at examining the predictive validity of the theoretical 1RM snatch (<i>snatch<sub>th</sub></i>) computed from the two-point snatch pull force-velocity relationship (FvR<sub>2</sub>) to determine actual snatch 1RM performance in elite weightlifters. Methods: Eight (three female, five male) elite weightlifters carried out a 1RM snatch test followed by a snatch pull test with loads of 80% and 110% of the previously determined 1RM snatch. Barbell kinematics were determined for all lifts using video-tracking. From the snatch pull barbell kinematics, the snatch pull FvR<sub>2</sub> was modeled and the <i>snatch<sub>th</sub></i> was calculated. Results: The main findings indicated a non-significant (<i>p</i> = 0.706) and trivial (<i>d</i> = 0.01) mean difference between the actual 1RM snatch performance and the <i>snatch<sub>th</sub></i>. Both measures showed an extremely large correlation (<i>r</i> = 0.99). The prediction accuracy of the actual 1RM snatch from <i>snatch<sub>th</sub></i> was 0.2 ± 1.5 kg (systematic bias ± standard deviation of differences). Conclusions: This study provides a new approach to estimate 1RM snatch performance in elite weightlifters using the snatch pull FvR<sub>2</sub>. The results demonstrate that the <i>snatch<sub>th</sub></i>-model accurately predicts 1RM snatch performance. |
