Table 3. Changes in selected athletic performance variables from pre- to post-training for each group.

Variable	VL10 (n = 14)		VL30 (n = 14)		Change		p-value	Hedges’ g (95% CI)
	Pre	Post	Pre	Post	VL10	VL30
Smith machine squat 1RM (kg)	78.9 ± 12.4	86.2 ± 11.5	80.9 ± 11.9	91.0 ± 12.2	9.2%	12.54%	0.001	-0.23 (-0.35-to 0.10)
Squat jump height (cm)	31.1 ± 2.0	33.6 ± 2.1	31.2 ± 2.3	33.1 ± 2.4	7.80%	6.18%	0.127	+0.23 (-0.07 to +0.52)
Countermovement jump height (cm)	35.1 ± 1.9	38.6 ± 2.7	35.4 ± 2.3	38.1 ± 2.5	9.76%	7.46%	0.058	+0.37 (+0.01 +0.75)
Standing long jump distance (cm)	195.4 ± 14.0	201.7 ± 12.7	194.7 ± 10.2	199.6 ± 10.2	3.25%	2.49%	0.031	+0.12 (+0.01 to +0.23)
30-m sprint time (s)	5.522 ± 0.208	5.463 ± 0.205	5.503 ± 0.170	5.469 ± 0.168	1.07%	0.61%	0.006	+0.13 (+0.04 to +0.22)

Values are mean±SD. Percentage changes indicate improvements and were calculated as [(post−pre)/pre] × 100, except for 30-m sprint time, for which [(pre − post)/pre] ×100 was used. The reported p values refer to the group×time interaction from the 2×2 mixed-design ANOVA. Hedges’g represents the standardized between-group difference in pre-to-post change using the pooled baseline SD; positive values favor VL10 and negative values favor VL30. 1RM, one-repetition maximum; CI, confidence interval; VL10, 10% velocity-loss group; VL30, 30% velocity-loss group.
