Using exercise to enhance physical fitness may have little impact on performers' movement patterns beyond the gym environment. This study examined the fitness and movement adaptations exhibited by firefighters in response to 2 training methodologies. Fifty-two firefighters were assigned to a movement-guided fitness (MOV), conventional fitness (FIT), or control (CON) group. Before and after 12 weeks of training, participants performed a fitness evaluation and laboratory-based test. Three-dimensional lumbar spine and frontal plane knee kinematics were quantified. Five whole-body tasks not included in the interventions were used to evaluate the transfer of training. FIT and MOV groups exhibited significant improvements in all aspects of fitness; however, only MOV exhibited improvements in spine and frontal plane knee motion control when performing each transfer task (effect sizes [ESs] of 0.2-1.5). FIT exhibited less controlled spine and frontal plane knee motions while squatting, lunging, pushing, and pulling (ES: 0.2-0.7). More MOV participants (43%) exhibited only positive posttraining changes (i.e., improved control), in comparison with FIT (30%) and CON (23%). Fewer negative posttraining changes were also noted (19, 25, and 36% for MOV, FIT, and CON). These findings suggest that placing an emphasis on how participants move while exercising may be an effective training strategy to elicit behavioral changes beyond the gym environment. For occupational athletes such as firefighters, soldiers, and police officers, this implies that exercise programs designed with a movement-oriented approach to periodization could have a direct impact on their safety and effectiveness by engraining desirable movement patterns that transfer to occupational tasks.
利用锻炼来增强身体素质,可能对运动员在健身房环境之外的运动模式影响甚微。本研究调查了消防员对两种训练方法的体能和运动适应性。五十二名消防员被分配到运动指导健身组(MOV)、传统健身组(FIT)或对照组(CON)。在为期12周的训练前后,参与者进行了体能评估和基于实验室的测试。对三维腰椎和额面膝关节运动学进行了量化。使用干预措施中未包含的五项全身任务来评估训练的迁移效果。FIT组和MOV组在体能的各个方面均有显著改善;然而,只有MOV组在执行每项迁移任务时,脊柱和额面膝关节的运动控制有所改善(效应大小[ESs]为0.2 - 1.5)。FIT组在深蹲、弓步、推和拉时,脊柱和额面膝关节的运动控制较差(ES:0.2 - 0.7)。与FIT组(30%)和CON组(23%)相比,更多MOV组参与者(43%)仅表现出训练后的积极变化(即控制改善)。训练后出现负面变化的情况也较少(MOV组、FIT组和CON组分别为19%、25%和36%)。这些发现表明,强调参与者在锻炼时的运动方式可能是一种有效的训练策略,能够引发健身房环境之外的行为变化。对于消防员、士兵和警察等职业运动员而言,这意味着采用以运动为导向的分期训练方法设计的锻炼计划,通过培养可迁移到职业任务中的理想运动模式,可能会直接影响他们的安全性和工作效率。
