Resistance training is an effective way to enhance strength in female youth but, to date, no researcher has meta-analysed its effect on muscular strength in that population.
This meta-analysis characterised female youths' adaptability to resistance training (RT). A second objective was to highlight the limitations of the body of literature with a view to informing future research.

Resistance training interventions in healthy females with a mean age between 8 and 18 years. Programmes of between 4 and 16 weeks' duration that included a control group.
The inverse-variance random effects model for meta-analyses was used because it allocates a proportionate weight to trials based on the size of their individual standard errors and facilitates analysis whilst accounting for heterogeneity across studies. Effect sizes, calculated from a measure of muscular strength, are represented by the standardised mean difference and are presented alongside 95% confidence intervals.
The magnitude of the main effect was 'small' (0.54, 95% confidence interval: 0.23-0.85). Effect sizes were larger in older (> 15 years; ES = 0.72 [0.23-1.21] vs. 0.38 [- 0.02-0.79]), taller (> 163 cm; ES = 0.67 [0.20-1.13] vs. 0.55 [0.08-1.02]) and heavier (< 54 kg; ES = 0.67 [0.30-1.03] vs. 0.53 [- 0.00-1.06]) participants.
Resistance training is effective in female youth. These findings can be used to inform the prescription of RT in female youth.
抗阻训练是增强女性青少年力量的有效方法，但迄今为止，还没有研究人员对其在该人群中的肌肉力量增强效果进行荟萃分析。
本荟萃分析描述了女性青少年对抗阻训练（RT）的适应性。第二个目的是突出文献的局限性，以便为未来的研究提供信息。

健康女性的 RT 干预研究，平均年龄在 8 至 18 岁之间；方案持续时间为 4 至 16 周，包含对照组。
由于它根据每个试验的个体标准误差的大小为试验分配相应的权重，并有助于在考虑到研究之间异质性的情况下进行分析，因此使用逆方差随机效应模型进行荟萃分析。从肌肉力量测量值计算的效应大小表示为标准化均数差，并与 95%置信区间一起呈现。
主要效应的幅度为“小”（0.54，95%置信区间：0.23-0.85）。在年龄较大（>15 岁；ES=0.72 [0.23-1.21] 与 0.38 [-0.02-0.79]）、身高较高（>163cm；ES=0.67 [0.20-1.13] 与 0.55 [0.08-1.02]）和体重较重（<54kg；ES=0.67 [0.30-1.03] 与 0.53 [-0.00-1.06]）的参与者中，效应值更大。
抗阻训练对女性青少年有效。这些发现可用于为女性青少年的 RT 处方提供信息。
