The US Army has traditionally utilized bent-knee sit-ups as part of physical training and testing. It is unknown whether the short-term effects of a core stabilization exercise program without sit-up training may result in decreased musculoskeletal injury incidence and work restriction compared with traditional training.
The objective of this study was to explore the short-term effects of a core stabilization exercise program (CSEP) without sit-up training and a traditional exercise program (TEP) on musculoskeletal injury incidence and work restriction.
The study was designed as a cluster randomized trial.
The setting was a 16-week training program at Fort Sam Houston (San Antonio, Texas).
The study participants were soldiers with a mean age of 22.9 years (SD=4,7, range=18-35) for whom complete injury data were available for analysis (n=1,141).
Twenty companies of soldiers were cluster randomized to complete the CSEP (10 companies of 542 soldiers) or the TEP (10 companies of 599 soldiers). The CSEP included exercises targeting the transversus abdominus and multifidus musculature. The TEP comprised exercises targeting the rectus abdominus, oblique abdominal, and hip flexor musculature.
Research staff recorded all injuries resulting in the inability to complete full duty responsibilities. Differences in the percentages of musculoskeletal injuries were examined with chi-square analysis; independent sample t tests were used to examine differences in the numbers of days of work restriction.
Of the 1,141 soldiers for whom complete injury data were available for analysis, 511 (44.8%) experienced musculoskeletal injuries during training that resulted in work restrictions. There were no differences in the percentages of soldiers with musculoskeletal injuries. There also were no differences in the numbers of days of work restriction for musculoskeletal injuries overall or specific to the upper extremity. However, soldiers who completed the TEP and experienced a low back injury had more days of work restriction: 8.3 days (SD=14.5) for the TEP group and 4.2 days (SD=8.0) for the CSEP group.
A limitation of this study was the inconsistent reporting of injuries during training. However, the rates of reporting were similar between the groups.
The incidence of musculoskeletal injuries was similar between the groups. There was marginal evidence that the CSEP resulted in fewer days of work restriction for low back injuries.
美国陆军传统上一直将屈膝仰卧起坐作为体能训练和测试的一部分。目前尚不清楚，如果不进行仰卧起坐训练，进行核心稳定性训练计划是否会导致与传统训练相比，肌肉骨骼损伤发生率和工作受限减少。
本研究旨在探讨无仰卧起坐训练的核心稳定性训练计划（CSEP）和传统训练计划（TEP）对肌肉骨骼损伤发生率和工作受限的短期影响。
该研究设计为集群随机试验。
在圣安东尼奥（德克萨斯州）的萨姆·休斯顿堡进行为期 16 周的训练计划。
共有 1141 名士兵参加了这项研究，他们的平均年龄为 22.9 岁（标准差=4,7,范围=18-35），并且有完整的损伤数据可用于分析。
20 个连队的士兵被集群随机分配完成 CSEP（10 个连队 542 名士兵）或 TEP（10 个连队 599 名士兵）。CSEP 包括针对横腹肌和多裂肌的练习。TEP 包括针对腹直肌、斜腹肌和髋屈肌的练习。
研究人员记录了所有导致无法完成全部工作职责的损伤。使用卡方分析检查肌肉骨骼损伤百分比的差异；使用独立样本 t 检验检查工作限制天数的差异。
在可用于分析的 1141 名士兵中，有 511 名（44.8%）在训练中因肌肉骨骼损伤而导致工作受限。有肌肉骨骼损伤的士兵百分比没有差异。整体或上肢特定的肌肉骨骼损伤的工作限制天数也没有差异。然而，完成 TEP 并经历下背痛的士兵的工作限制天数更多：TEP 组为 8.3 天（标准差=14.5），CSEP 组为 4.2 天（标准差=8.0）。
本研究的一个局限性是训练期间的损伤报告不一致。然而，两组的报告率相似。
两组的肌肉骨骼损伤发生率相似。有边缘证据表明，CSEP 可减少下背痛的工作限制天数。
