Abstract

BACKGROUND

Military organizations use movement quality screening for prediction of injury risk and performance potential. Currently, evidence of an association between movement quality and performance is limited. Recent work has demonstrated that external loading strengthens the relationship between movement screens and performance outcomes. Such loading may therefore steer us toward robust implementations of movement quality screens while maintaining their appeal as cost effective, field-expedient tools.

PURPOSE

The purpose of the current study was to quantify the effect of external load-bearing on the relationship between clinically rated movement quality and tactical performance outcomes while addressing the noted limitations.

STUDY DESIGN

Crossover Trial.

METHODS

Fifty young adults (25 male, 25 female, 22.98 ± 3.09 years, 171.95 ± 11.46 cm, 71.77 ± 14.03 kg) completed the Functional Movement Screen™ with (FMS™W) and without (FMS™C) a weight vest in randomized order. Following FMS™ testing, criterion measures of tactical performance were administered, including agility T-Tests, sprints, a 400-meter run, the Mobility for Battle (MOB) course, and a simulated casualty rescue. For each performance outcome, regression models were selected via group lasso with smoothed FMS™ item scores as candidate predictor variables.

RESULTS

For all outcomes, proportion of variance accounted for was greater in FMS™W (R = ;0.22 [T-Test], 0.29 [Sprint], 0.17 [400 meter], 0.29 [MOB], and 0.11 [casualty rescue]) than in FMS™C (R = ;0.00 [T-Test], 0.11 [Sprint], 0.00 [400 meter], 0.19 [MOB], and 0.00 [casualty rescue]). From the FMS™W condition, beneficial performance effects (p<0.05) were observed for Deep Squat (sprint, casualty rescue), Hurdle Step (T-Agility, 400 meter run), Inline Lunge (sprint, MOB), and Trunk Stability Push Up (all models). Similar effects for FMS™C item scores were limited to Trunk Stability Push Up (p<0.05, all models).

CONCLUSIONS

The present study extends evidence supporting the validity of load-enhanced movement quality screening as a predictor of tactical performance ability. Future designs should seek to identify mechanisms explaining this effect.

摘要

背景

军事组织采用动作质量筛查来预测受伤风险和表现潜力。目前，动作质量与表现之间关联的证据有限。近期研究表明，外部负荷强化了动作筛查与表现结果之间的关系。因此，这种负荷可能引导我们在保持动作质量筛查作为经济高效、便于现场操作工具吸引力的同时，实现其稳健应用。

目的

本研究的目的是量化外部负重对临床评定的动作质量与战术表现结果之间关系的影响，同时解决所指出的局限性。

研究设计

交叉试验。

方法

50名年轻人（25名男性，25名女性，年龄22.98±3.09岁，身高171.95±11.46厘米，体重71.77±14.03千克）以随机顺序完成了佩戴（FMS™W）和不佩戴（FMS™C）负重背心的功能性动作筛查™。在FMS™测试之后，进行战术表现的标准测量，包括敏捷性T测试、短跑、400米跑、战斗机动性（MOB）课程以及模拟伤员救援。对于每个表现结果，通过组套索选择回归模型，将平滑后的FMS™项目得分作为候选预测变量。

结果

对于所有结果，FMS™W（R = 0.22 [T测试]，0.29 [短跑]，0.17 [400米跑]，0.29 [MOB]，0.11 [伤员救援]）中解释的方差比例大于FMS™C（R = 0.00 [T测试]，0.11 [短跑]，0.00 [400米跑]，0.19 [MOB]，0.00 [伤员救援]）。在FMS™W条件下，深蹲（短跑、伤员救援）、跨栏步（T敏捷性、400米跑）、直线弓步蹲（短跑、MOB）和躯干稳定性俯卧撑（所有模型）观察到有益的表现效果（p<0.05）。FMS™C项目得分的类似效果仅限于躯干稳定性俯卧撑（p<0.05，所有模型）。
