Side-step cutting is a common evasive maneuver which is typically performed without prior anticipation. Studies quantifying joint work and its inter-joint proportions in cutting have not accounted for work done by the foot, even though this segment has been shown to be an important source of mechanical work in walking, running, and landing. The aims of this study were to: (1) quantify the magnitude of foot work performed and provide a more precise account of percentage joint work during cutting, and (2) examine the effect, a lack of anticipation had on these variables. Three-dimensional motion capture with forceplates were used to assess the cutting behaviour of 17 healthy participants. All participants performed a 45° cut with an approach speed of 4 m/s. Hip, knee, and ankle joint work were calculated using inverse dynamics; whilst foot work was quantified using the Unified-Deformable foot method. The foot contributed up to 12.45% and 3.09% of total limb negative and positive work, respectively. Unanticipated cutting significantly reduced ankle positive work (-0.09 J/kg [95% CI −0.13 to −0.06], P < 0.001) and significantly reduced percentage ankle positive work (-2.17% [95% CI −3.47 to −0.86], P = 0.001). The foot performs as much negative work as the hip but had only a minor contribution to positive work during cutting. Anticipation had a negligible influence on joint work and its inter-joint proportions. The foot should not be neglected in understanding whole-body dynamics during cutting, with greater understanding of its function potentially useful for informing athletic footwear design and cutting technique modification.

边步切割是一种常见的规避操作，通常无需事先预期即可执行。定量研究关节活动及其在切割中的相互比例的研究并未考虑脚所完成的工作，即使该部分已被证明是步行，跑步和着陆中机械工作的重要来源。这项研究的目的是：（1）量化所进行的脚部工作的幅度，并提供更精确的切割过程中关节工作百分比的信息，以及（2）检查效果，这些变量缺乏预期。使用压板进行三维运动捕捉来评估17名健康参与者的切割行为。所有参与者均以4 m / s的进近速度进行了45°切割。使用逆动力学计算髋，膝和踝关节的功。而脚部功用统一可变形脚部法进行了量化。脚分别占总肢体负功和正功的12.45％和3.09％。意外切割会显着降低踝关节正功（-0.09 J / kg [95％CI -0.13至-0.06]，P <0.001），并显着降低踝关节正功百分比（-2.17％[95％CI -3.47至-0.86]， P = 0.001）。脚的活动与臀部的活动一样多，但是在切割过程中，脚对活动的贡献很小。预期对联合工作及其相互之间的影响几乎没有影响。在了解切割过程中的全身动态时，不应忽略脚，而应更多地了解其功能，这可能有助于告知运动鞋的设计和切割技术的改进。
