确定阻力训练处方 (RTx) 变量（负荷、组数和频率）的不同组合如何影响肌肉力量和肥大。 MEDLINE、Embase、Emcare、SPORTDiscus、CINAHL 和 Web of Science 的检索截止至 2022 年 2 月。纳入了包括健康成人在内的随机试验，比较了至少 2 种预定义条件（非运动控制 (CTRL) 和 12 RTx，按负荷、组数和/或每周频率进行区分），并报告了肌肉力量和/或肥大情况。使用系统回顾和贝叶斯网络荟萃分析方法来比较 RTx 和 CTRL。累积排名曲线下的表面值用于对条件进行排名。通过阈值分析评估置信度。力量网络包括 178 项研究（n=5097；女性=45%）。肥大网络包括 119 项研究（n=3364；女性=47%）。所有 RTx 在肌肉力量和肥大方面均优于 CTRL。较高负荷（> 单次重复最大值的 80%）处方可以最大限度地提高力量，并且所有处方都可以相对促进肌肉肥大。虽然许多处方的计算效果相似，但高负荷、多组、每周三次训练（标准化平均差（95% 可信区间）；1.60（1.38 至 1.82）对比 CTRL）是力量排名最高的 RTx，高负荷、多组、每周两次训练（0.66（0.47 至 0.85）对比 CTRL）是强度排名最高的 RTx 肥大。阈值分析表明这些结果非常稳健。与不运动相比，所有 RTx 都能促进力量和肥大。排名最高的力量处方涉及更高的负荷，而排名最高的增肌处方则包括多组训练。 CRD42021259663 和 CRD42021258902。
To determine how distinct combinations of resistance training prescription (RTx) variables (load, sets and frequency) affect muscle strength and hypertrophy. MEDLINE, Embase, Emcare, SPORTDiscus, CINAHL, and Web of Science were searched until February 2022. Randomised trials that included healthy adults, compared at least 2 predefined conditions (non-exercise control (CTRL) and 12 RTx, differentiated by load, sets and/or weekly frequency), and reported muscle strength and/or hypertrophy were included. Systematic review and Bayesian network meta-analysis methodology was used to compare RTxs and CTRL. Surface under the cumulative ranking curve values were used to rank conditions. Confidence was assessed with threshold analysis. The strength network included 178 studies (n=5097; women=45%). The hypertrophy network included 119 studies (n=3364; women=47%). All RTxs were superior to CTRL for muscle strength and hypertrophy. Higher-load (>80% of single repetition maximum) prescriptions maximised strength gains, and all prescriptions comparably promoted muscle hypertrophy. While the calculated effects of many prescriptions were similar, higher-load, multiset, thrice-weekly training (standardised mean difference (95% credible interval); 1.60 (1.38 to 1.82) vs CTRL) was the highest-ranked RTx for strength, and higher-load, multiset, twice-weekly training (0.66 (0.47 to 0.85) vs CTRL) was the highest-ranked RTx for hypertrophy. Threshold analysis demonstrated these results were extremely robust. All RTx promoted strength and hypertrophy compared with no exercise. The highest-ranked prescriptions for strength involved higher loads, whereas the highest-ranked prescriptions for hypertrophy included multiple sets. CRD42021259663 and CRD42021258902.
