Description of countermovement jump results at different moments when control and plyometric conditioning activity were performed.
| Moments | Interventions | Mean ± SD (cm) | Mean difference (cm) | ES (Cohen's d) | ES magnitudes |
|---|---|---|---|---|---|
| Pre | Control | 33.59 ± 8.70 | |||
| Plyometric CA | 33.71 ± 8.69 | ||||
| 1 min | Control | 33.76 ± 9.19 | 0.17 | 0.02 | Null |
| Plyometric CA | 37.30 ± 9.47 | 3.59 | 0.41 | Small | |
| 3 min | Control | 34.59 ± 9.24 | 1.00 | 0.11 | Null |
| Plyometric CA | 36.45 ± 9.40 | 2.74 | 0.32 | Small | |
| 6 min | Control | 34.52 ± 9.28 | 0.93 | 0.11 | Null |
| Plyometric CA | 36.04 ± 9.21 | 2.33 | 0.27 | Small | |
| 9 min | Control | 34.02 ± 8.72 | 0.43 | 0.05 | Null |
| Plyometric CA | 35.58 ± 9.48 | 1.87 | 0.22 | Small |
Mean difference: comparisons of mean differences of each moment compared to pre for control and plyometric conditioning activity (CA). ES: effect size (Cohen's d) of each moment compared to pre for control and plyometric conditioning activity (CA). ES magnitudes: d (0.20) = small, d (0.50) = medium, d (0.80) = large.
