The purpose of this study was to examine the effect of minimalist running shoes on oxygen uptake during running before and after a 10-week transition from traditional to minimalist running shoes. Twenty-five recreational runners (no previous experience in minimalist running shoes) participated in submaximal VO2 testing at a self-selected pace while wearing traditional and minimalist running shoes. Ten of the 25 runners gradually transitioned to minimalist running shoes over 10 weeks (experimental group), while the other 15 maintained their typical training regimen (control group). All participants repeated submaximal VO2 testing at the end of 10 weeks. Testing included a 3 minute warm-up, 3 minutes of running in the first pair of shoes, and 3 minutes of running in the second pair of shoes. Shoe order was randomized. Average oxygen uptake was calculated during the last minute of running in each condition. The average change from pre- to post-training for the control group during testing in traditional and minimalist shoes was an improvement of 3.1 ± 15.2% and 2.8 ± 16.2%, respectively. The average change from pre- to post-training for the experimental group during testing in traditional and minimalist shoes was an improvement of 8.4 ± 7.2% and 10.4 ± 6.9%, respectively. Data were analyzed using a 2-way repeated measures ANOVA. There were no significant interaction effects, but the overall improvement in running economy across time (6.15%) was significant (p = 0.015). Running in minimalist running shoes improves running economy in experienced, traditionally shod runners, but not significantly more than when running in traditional running shoes. Improvement in running economy in both groups, regardless of shoe type, may have been due to compliance with training over the 10-week study period and/or familiarity with testing procedures. Key pointsRunning in minimalist footwear did not result in a change in running economy compared to running in traditional footwear prior to 10 weeks of training.Both groups (control and experimental) showed an improvement in running economy in both types of shoes after 10 weeks of training.After transitioning to minimalist running shoes, running economy was not significantly different while running in traditional or minimalist footwear.
本研究的目的是在从传统跑鞋向极简跑鞋过渡10周前后，考察极简跑鞋对跑步过程中摄氧量的影响。25名业余跑步者（此前无穿极简跑鞋的经验）在穿着传统跑鞋和极简跑鞋时，以自我选择的速度参加了次最大摄氧量测试。25名跑步者中有10名在10周内逐渐过渡到极简跑鞋（实验组），而另外15名保持其典型的训练方案（对照组）。所有参与者在10周结束时重复进行次最大摄氧量测试。测试包括3分钟热身、穿着第一双鞋跑步3分钟以及穿着第二双鞋跑步3分钟。鞋的顺序是随机的。在每种情况下跑步的最后一分钟计算平均摄氧量。对照组在穿着传统跑鞋和极简跑鞋测试期间，训练前到训练后的平均变化分别为提高3.1±15.2%和2.8±16.2%。实验组在穿着传统跑鞋和极简跑鞋测试期间，训练前到训练后的平均变化分别为提高8.4±7.2%和10.4±6.9%。数据使用双向重复测量方差分析进行分析。没有显著的交互作用，但随着时间推移跑步经济性的总体改善（6.15%）是显著的（p = 0.015）。对于有经验的、穿着传统跑鞋的跑步者来说，穿极简跑鞋跑步可提高跑步经济性，但并不比穿传统跑鞋跑步时显著提高更多。两组跑步经济性的改善，无论鞋的类型如何，可能是由于在为期10周的研究期间遵守训练计划和/或熟悉测试程序。关键点在训练10周之前，与穿传统跑鞋跑步相比，穿极简跑鞋跑步并未导致跑步经济性发生变化。两组（对照组和实验组）在训练10周后，两种类型的鞋子跑步经济性均有所改善。过渡到极简跑鞋后，穿传统跑鞋或极简跑鞋跑步时，跑步经济性没有显著差异。
