Physical characteristics pre-intervention.

Variable	FRT (n = 14)	TST (n = 11)	p Value (95% CI)	Effect Size
Height (cm)	155 ± 8	156 ± 9	p = 0.83 (−7.78 to 6.33)	g = 0.11
Body mass (kg)	43.1 ± 9.0	46.3 ± 10.4	p = 0.41 (−11.29 to 4.77)	g = 0.32
Age at PHV (yr)	13.1 ± 1.3	13.2 ± 1.1	p = 0.85 (−1.09 to 0.90)	g = 0.08

FRT, flywheel resistance training; TST, traditional strength training; PHV, peak height velocity; CI, confidence interval. Effect size is expressed as Hedges’ g. Data are presented as mean ± SD.
