Effects of a blocked versus an alternated sequence of balance and plyometric training on physical performance in youth soccer players

Table 1 Characteristics of the study participants by intervention group

Characteristic	Blocked BTPT (n = 8)	Alternated BTPT (n = 9)	p-value
Age [years]	13.0 ± 0.9	13.1 ± 1.0	.990
Body mass [kg]	53.2 ± 8.7	52.4 ± 10.2	.860
Body height [cm]	166.3 ± 5.9	164.2 ± 9.5	.555
BMI [kg/m²]	19.1 ± 2.3	19.3 ± 1.9	.910
Maturity offset^a [years from PHV]	−0.2 ± 0.3	−0.3 ± 0.4	.555
Dominant leg length^b [cm]	102.5 ± 4.1	99.6 ± 9.2	.374
Non-dominant leg length [cm]	102.1 ± 4.1	99.5 ± 8.8	.398
Training volume [min/week]	385	385

Values are mean values ± standard deviations. ^aMaturity offset was calculated by using the formula provided by Moore et al. [12]. ^bLeg dominance was determined according to the lateral preference inventory provided by Coren [13]. BMI body mass index, BTPT balance and plyometric training, PHV peak height velocity
