INTRODUCTION
Force plate systems are increasingly utilized in the armed forces that claim to identify individuals at risk of musculoskeletal injury. However, factors influencing injury risk scores from a force plate system (SpartaScienceTM), and the effects of experimental perturbations on these scores, remain unclear.
METHODS
Healthy males (n = 823; 22.7 ± 3.9 years) performed a countermovement jump (CMJ) on SpartaScienceTM force plates. Multiple regression analysis was used to identify predictors of the system's proprietary Musculoskeletal (MSK) Health score which were then experimentally perturbed. Twelve males (30.9 ± 4.3 years) participated in a test-retest reliability study, performing three standard CMJs and one experimentally manipulated jump (50% effort) due to the observed relationship between the MSK Health score, vertical jump height and body weight.
RESULTS
The MSK Health score was negatively correlated with vertical jump height and positively with body weight (R2 = 0.59, p < 0.001). Each inch increase in jump height decreased the MSK Health score by an average of 1.27 units (95% CI: 1.17, 1.36), while each pound of body weight increased it by 0.12 units (95% CI: 0.11, 0.13). Notably, 83% of participants in the reliability study improved their MSK Health score on the 50% effort jump.
CONCLUSIONS
The study revealed atypical relationships between MSK Health scores, vertical jump height, and body weight, with vertical jump height playing a majority role in predicting the principal output (MSK Health score). Findings indicated a higher injury risk with greater jump height but a lower risk with increased body weight. Additionally, MSK Health scores paradoxically improved with lower effort (i.e. lower vertical jump height) which highlights the dangers of using undisclosed and unvetted algorithms for the prediction of health outcomes.

运动医学中的算法审计:SpartaScienceTM 测力台系统的检查。
引言 测力板系统越来越多地用于声称可以识别有肌肉骨骼损伤风险的个体的武装部队。然而,影响测力台系统 (SpartaScienceTM) 损伤风险评分的因素,以及实验扰动对这些评分的影响,仍不清楚。方法 健康男性 (n = 823;22.7 ± 3.9 岁) 在 SpartaScienceTM 测力板上进行了反向运动跳跃 (CMJ)。多元回归分析用于确定系统专有的肌肉骨骼 (MSK) 健康评分的预测因子,然后对这些预测因子进行实验干扰。12 名男性 (30.9 ± 4.3 岁) 参加了一项重测信度研究,由于观察到 MSK 健康评分、垂直跳跃高度和体重之间的关系,他们进行了 3 次标准 CMJ 和 1 次实验操纵的跳跃(50% 的努力)。结果 MSK 健康评分与垂直跳跃高度呈负相关,与体重呈正相关 (R2 = 0.59,p < 0.001)。跳跃高度每增加一英寸,MSK 健康评分平均降低 1.27 个单位(95% CI:1.17,1.36),而每磅体重增加 0.12 个单位(95% CI:0.11,0.13)。值得注意的是,可靠性研究中 83% 的参与者在 50% 的努力跳跃中提高了他们的 MSK Health 分数。结论 该研究揭示了 MSK Health 评分、垂直跳跃高度和体重之间的非典型关系,其中垂直跳跃高度在预测主要输出(MSK Health 评分)中起主要作用。研究结果表明,跳跃高度越高,受伤风险越高,但体重增加的风险越高。此外,MSK Health 评分反常地提高了,但工作量较小(即 较低的垂直跳跃高度),该修正强调了使用未披露和未经审查的算法来预测健康结果的危险。
