Abstract

This cross-sectional study investigated the impact of age and playing position, controlling for maturity, on physical fitness indicators in 303 adolescent female netball players aged 12.0 to 15.9 years. Assessments included estimated maximal oxygen uptake (VO2max) via the 20 m shuttle run test, 10 m and 20 m sprints, change of direction speed (CODS) using the 505 test, and muscle power via the medicine ball chest throw (MBCT) and countermovement vertical jump (CMJ). Participants were grouped by age (12 to 15 years) and playing position (non-circle and circle players), with age at peak height velocity as a covariate for maturity. Results revealed that, at 15 years, CMJ height was greater than at 12 years and 13 years (p < 0.05, partial η2 = 0.048). MBCT distance increased across age groups (p < 0.01, partial η2 = 0.323). Age had no impact on sprints, VO2max, or CODS. Non-circle players outperformed circle players in the 10 m sprint (p = 0.042, partial η2 = 0.016) and 20 m sprints (p = 0.010, partial η2 = 0.025) and displayed higher VO2max (p < 0.001, partial η2 = 0.036). Circle players were taller (p = 0.046, partial η2 = 0.014) and heavier (p < 0.001, partial η2 = 0.040) than non-circle players. Playing positions showed no differences in CMJ and MBCT. In adolescent female netball players, only muscle power is influenced by age, while non-circle players exhibit superior aerobic fitness and speed compared to circle players. Coaches may be able to utilize the distinct age and playing position traits of adolescent netballers to inform player selection and design targeted training programs.

年龄和比赛位置对青少年女子无挡板篮球运动员现场体能测量的影响
这项横断面研究调查了年龄和比赛位置对 303 名 12.0 至 15.9 岁青少年女子网球运动员体能指标的影响,并对成熟度进行了控制。评估包括通过 20 米往返跑测试、10 米和 20 米短跑估计最大摄氧量(VO2max),通过 505 测试估计变向速度(CODS),以及通过药球胸前投掷(MBCT)和反运动垂直跳跃(CMJ)估计肌肉力量。参赛者按年龄(12 至 15 岁)和比赛位置(非圈内球员和圈内球员)分组,身高峰值速度年龄作为成熟度的协变量。结果显示,15 岁时的 CMJ 高度大于 12 岁和 13 岁时(p < 0.05,局部 η2 = 0.048)。MBCT距离在各年龄组中都有所增加(p < 0.01,部分η2 = 0.323)。年龄对短跑、VO2max 或 CODS 没有影响。在 10 米短跑(p = 0.042,部分 η2 = 0.016)和 20 米短跑(p = 0.010,部分 η2 = 0.025)中,非圆周运动者的表现优于圆周运动者,其 VO2max 也更高(p < 0.001,部分 η2 = 0.036)。与非圈内球员相比,圈内球员更高(p = 0.046,部分 η2 = 0.014),更重(p < 0.001,部分 η2 = 0.040)。比赛位置在 CMJ 和 MBCT 方面没有差异。在青少年女子网球运动员中,只有肌肉力量受到年龄的影响,而非圈内球员的有氧体能和速度则优于圈外球员。教练员可以利用青少年拦网运动员不同的年龄和位置特征来选择球员和设计有针对性的训练计划。
