To evaluate if takeoff speed can be predicted using peak-speed from a linear position transducer (LPT), 21 rowing athletes performed hexagonal-bar jumps in line with the National Team testing protocol. Predictive validity was assessed by comparing peak-speed from a LPT to the criterion measure takeoff speed collected from force plates. The relationship between peak-speed and takeoff speed was: Takeoff Speed = 1.21[dot]PeakSpeed-0.68, and the correlation was statistically significant (r= 0.990, p < 0.05). The Bland-Altman plot indicated that the 95% limits of agreement ranged from -0.130 m[dot]s[superscript -1] to 0.125 m[dot]s[superscript -1], with points above and below the zero line, suggesting there is no systematic bias. The mean difference in speed was 0.18%. This research shows that takeoff speed can be accurately predicted from peak-speed using a LPT. This allows practitioners to quickly and accurately estimate jump height when accessibility and portability of testing equipment are limiting factors in the field.
