Abstract

BACKGROUND

Reference values of body fat for competitive volleyball players are lacking, making it difficult to interpret measurement results. This review systematically summarized published data on the relative body fat of volleyball players and calculated potential differences between sex, measurement method, and competitive level.

METHODS

The protocol followed the Preferred Reported Items for Systematic Reviews and Meta-Analysis guidelines. The literature search was conducted using five electronic databases to retrieve all relevant publications from January 1, 2010, to July 1, 2021. The 63 studies including 2607 players that met the inclusion criteria were analyzed using random-effects models. Data were reported as pooled mean body fat with 95% confidence intervals.

RESULTS

Body fat for males and females was 12.8% (11.9-13.8%) and 22.8% (21.9-23.7%), respectively. Body fat was 18.3% (16.3-20.4%) measured via skinfolds, 18.4% (15.6-21.2%) via bioelectrical impedance analysis, 24.2% (20.4-28.0%) via dual-energy x-ray absorptiometry and 21.6% (17.4-25.8%) via densitometry. Regional, national, and international-level players had body fat values of 19.5% (17.8-21.2%), 20.3% (18.6-22.0%), and 17.9% (15.7-20.4%), respectively. When the meta-regression was adjusted for the variables sex, measurement method, and competitive level, a significant difference between sex ( < 0.001), dual-energy x-ray absorptiometry and skinfolds ( = 0.02), and national and international-level players ( = 0.02) was found. However, sensitivity analysis revealed that findings regarding measurement method and competitive level were not robust and should, therefore, be interpreted with caution.

CONCLUSIONS

Despite the limitations of published data, this meta-analysis provided pooled values for body fat of male and female volleyball players for different competitive levels and measurement methods.

摘要

背景

缺乏竞技排球运动员体脂的参考值，使得测量结果难以解读。本综述系统总结了已发表的排球运动员体脂相关数据，并计算了性别、测量方法和竞技水平之间的潜在差异。

方法

该方案遵循系统评价和荟萃分析首选报告项目的指南。使用五个电子数据库进行文献检索，以检索 2010 年 1 月 1 日至 2021 年 7 月 1 日所有相关的出版物。纳入标准的 63 项研究包含 2607 名运动员，使用随机效应模型进行分析。数据以 95%置信区间的 pooled mean body fat 报告。

结果

男性和女性的体脂分别为 12.8%（11.9-13.8%）和 22.8%（21.9-23.7%）。通过皮褶厚度测量的体脂为 18.3%（16.3-20.4%），通过生物电阻抗分析测量的体脂为 18.4%（15.6-21.2%），通过双能 X 射线吸收测量的体脂为 24.2%（20.4-28.0%），通过密度测量的体脂为 21.6%（17.4-25.8%）。区域性、国家级和国际级运动员的体脂值分别为 19.5%（17.8-21.2%）、20.3%（18.6-22.0%）和 17.9%（15.7-20.4%）。当 meta 回归考虑了性别、测量方法和竞技水平等变量时，发现性别之间存在显著差异（ < 0.001），双能 X 射线吸收测量法和皮褶厚度测量法之间存在显著差异（ = 0.02），以及国家级和国际级运动员之间存在显著差异（ = 0.02）。然而，敏感性分析表明，关于测量方法和竞技水平的发现并不稳健，因此应谨慎解释。
