This study investigated whether male runners improve running performance, running economy, ankle plantar flexor strength, and alter running biomechanics and lower limb bone mineral density when gradually transitioning to using minimalist shoes for 100% of weekly running. The study was a planned follow-up of runners (n = 50) who transitioned to minimalist or conventional shoes for 35% of weekly structured training in a previous 6-week randomised controlled trial. In that trial, running performance and economy improved more with minimalist shoes than conventional shoes. Runners in each group were instructed to continue running in their allocated shoe during their own preferred training programme for a further 20 weeks while increasing allocated shoe use to 100% of weekly training. At the 20-week follow-up, minimalist shoes did not affect performance (effect size: 0.19; p = 0.218), running economy (effect size: ≤ 0.24; p ≥ 0.388), stride rate or length (effect size: ≤ 0.12; p ≥ 0.550), foot strike (effect size: ≤ 0.25; p ≥ 0.366), or bone mineral density (effect size: ≤ 0.40; p ≥ 0.319). Minimalist shoes increased plantar flexor strength more than conventional shoes when runners trained with greater mean weekly training distances (shoe*distance interaction: p = 0.036). After greater improvements with minimalist shoes during the initial six weeks of a structured training programme, increasing minimalist shoe use from 35% to 100% over 20 weeks, when runners use their own preferred training programme, did not further improve performance, running economy or alter running biomechanics and lower limb bone mineral density. Minimalist shoes improved plantar flexor strength more than conventional shoes in runners with greater weekly training distances.
本研究旨在探讨男性跑步者在逐渐过渡到 100%使用极简跑鞋进行每周跑步的情况下，是否能提高跑步表现、跑步经济性、踝关节跖屈肌力量，以及改变跑步生物力学和下肢骨密度。本研究是对先前 6 周随机对照试验中过渡到极简或传统跑鞋进行 35%每周结构化训练的跑步者（n=50）的计划随访。在该试验中，与传统跑鞋相比，极简跑鞋能更有效地提高跑步表现和经济性。在另一项试验中，每组跑步者都被指示在他们自己喜欢的训练计划中继续穿着他们分配的鞋子进行额外的 20 周训练，同时将分配的鞋子使用量增加到每周训练的 100%。在 20 周的随访中，极简跑鞋并没有影响跑步表现（效应量：0.19；p=0.218）、跑步经济性（效应量：≤0.24；p≥0.388）、步频或步长（效应量：≤0.12；p≥0.550）、足着地方式（效应量：≤0.25；p≥0.366）或骨密度（效应量：≤0.40；p≥0.319）。当跑步者以更大的平均每周训练距离进行训练时，极简跑鞋比传统跑鞋更能增加跖屈肌力量（鞋*距离交互作用：p=0.036）。在结构化训练计划的最初六周内，极简跑鞋的表现有了更大的提高，20 周内将极简跑鞋的使用量从 35%增加到 100%，当跑步者使用自己喜欢的训练计划时，并没有进一步提高表现、跑步经济性或改变跑步生物力学和下肢骨密度。在每周训练距离较大的跑步者中，极简跑鞋比传统跑鞋更能提高跖屈肌力量。
