Barefoot running has gained popularity among physical activity practitioners, but there is a lack of information regarding the acute adaptations to this running technique without supervision. Information about acute adaptations can help to define the best way to insert barefoot running in the routine of runners willing to, and also provide orientation for those people who want to experience this technique.
What acute adaptations can be observed among recreational runners exposed to barefoot running?
Sagittal 2D kinematics, plantar pressure, foot sensitivity and delayed onset muscle soreness were compared between conditions of shod and barefoot running in 13 recreational runners who performed two trials of 5 km treadmill running.
We found an acute effect of barefoot running on foot landing that changes from a rearfoot strike to a forefoot strike pattern. This change most likely contributed to the increase in neuromuscular recruitment of calf muscles (i.e. gastrocnemius and soleus) resulting in higher perception of delayed onset muscle soreness. Barefoot running also elicited higher stride cadence. Plantar pressure before and after running revealed higher pressure in the different foot regions after barefoot running. Foot sensitivity increased after running regardless of the footwear condition.
Barefoot running has acute effects on running technique including higher perception of delayed onset muscle soreness in the 48 h following the exercise.
Our results highlight the importance of following participants for days after a first session of barefoot running in order to properly manage the acute adaptation periods as well provide precise advices for those trying the barefoot technique.
赤脚跑步在体育活动从业者中越来越受欢迎，但在没有监督的情况下，关于这种跑步技术的急性适应的信息却很少。关于急性适应的信息可以帮助确定将赤脚跑步纳入有意愿的跑步者日常训练的最佳方式，并为那些想要体验这种技术的人提供指导。
在没有监督的情况下，赤脚跑步会对休闲跑者产生哪些急性适应？
在 13 名休闲跑者进行两次 5 公里跑步机跑步试验中，比较了赤脚和穿鞋跑步时的矢状面 2D 运动学、足底压力、足部敏感度和延迟性肌肉酸痛。
我们发现赤脚跑步对足部着地有急性影响，从后足着地转变为前足着地模式。这种变化很可能导致小腿肌肉（即腓肠肌和比目鱼肌）的神经肌肉募集增加，从而导致更高的延迟性肌肉酸痛感知。赤脚跑步还产生了更高的步频。跑步前后的足底压力显示，赤脚跑步后不同足部区域的压力更高。无论穿着哪种鞋子，跑步后足部敏感度都会增加。
赤脚跑步对跑步技术有急性影响，包括在运动后 48 小时内更高的延迟性肌肉酸痛感知。
我们的结果强调了在第一次赤脚跑步后几天内跟踪参与者的重要性，以便正确管理急性适应期，并为那些尝试赤脚技术的人提供准确的建议。
