In recent years, athletes have ventured into ultra-endurance and adventure racing events, which tests their ability to race, navigate, and survive. These events often require race participants to carry some form of load, to bear equipment for navigation and survival purposes. Previous studies have reported specific alterations in biomechanics when running with load which potentially influence running performance and injury risk. We hypothesize that a biomechanically informed neuromuscular training program would optimize running mechanics during load carriage to a greater extent than a generic strength training program.
This will be a two group, parallel randomized controlled trial design, with single assessor blinding. Thirty healthy runners will be recruited to participate in a six weeks neuromuscular training program. Participants will be randomized into either a generic training group, or a biomechanically informed training group. Primary outcomes include self-determined running velocity with a 20 % body weight load, jump power, hopping leg stiffness, knee extensor and triceps-surae strength. Secondary outcomes include running kinetics and kinematics. Assessments will occur at baseline and post-training.
To our knowledge, no training programs are available that specifically targets a runner's ability to carry load while running. This will provide sport scientists and coaches with a foundation to base their exercise prescription on.

近年来，运动员涉足超耐力和冒险竞赛项目，这些项目考验他们的竞赛、导航和生存能力。这些赛事通常要求参赛者携带某种形式的负重，以携带用于导航和生存目的的装备。先前的研究报告了负重跑步时生物力学的特定变化，这可能会影响跑步表现和受伤风险。我们假设，一个基于生物力学的神经肌肉训练计划在负重跑步过程中比一般的力量训练计划能更大程度地优化跑步力学。
这将是一个两组平行随机对照试验设计，采用单评估者盲法。将招募30名健康跑步者参加为期六周的神经肌肉训练计划。参与者将被随机分为一般训练组或基于生物力学的训练组。主要结果包括在背负20%体重负荷时的自我决定跑步速度、跳跃功率、单腿跳刚度、伸膝力量和小腿三头肌力量。次要结果包括跑步动力学和运动学。评估将在基线和训练后进行。
据我们所知，目前尚无专门针对跑步者负重跑步能力的训练计划。这将为运动科学家和教练提供一个制定运动处方的基础。
