Popis: | This study aimed to determine the criterion validity of the ADR jumping photocell when compared to a motion capture system and to examine the within-session test–retest reliability of the instrument. Thirteen highly trained female volleyball players performed ten countermovement jumps (CMJ) with two minutes rest in-between trials. Jumps were recorded simultaneously by both devices to compare the outcomes. The main results showed significant mean differences between devices (10.6 cm, p < 0.001; ES = 0.9), high Spearman’s correlations (ρ = 0.95), weak CCC (0.25), and SEE = 0.92 cm. Bland–Altman’s plot indicated high systematic errors (10.5 cm), heteroscedasticity of error (slope = 0.026), and all values included among the limits of agreement. The within-session reliability (internal consistency) was very high (ICC = 0.96; CCC = 0.94; SEM = 1.18 cm; CV = 4.21%). In addition, the sensitivity of the instrument showed values of SWC = 0.33 cm. In conclusion, ADR jumping is a valid instrument for the estimation of CMJ in highly trained female volleyball players. Furthermore, the instrument is shown to be a consistent tool in the measurement of CMJ. This work was supported by Generalitat Valenciana (grant number GV/2021/098). |
