Physical activity is known to benefit health while muscle activation and movements performed during occupational work in contrast may result in work-related musculoskeletal disorders. Therefore, we posed the research question: which mode of muscle activation may result in a reversal of work-related disorders? To address this, we performed electromyographic (EMG) and kinematic assessments of workers with diverse exposure categories: sedentary monotonous work, prolonged walking/standing, and physically heavy work. The various job-specific exposure variables could be categorized in terms of duration, intensity, repetition, static component, peak force etc. that were subsequently identified as risk factors. Based on sports science principles we developed tailored exercise programs to counteract job exposure. EMG activity during exercise training was monitored to identify principal differences between exercise training and job patterns. Evidence from more than 20 RCT studies including >4000 workers showed positive effects such as decreased muscle pain and increased workability. Finally, we identified plausible underlying mechanisms in muscle tissue – human and animal - that confirmed metabolic, morphological, and hormonal changes with e.g. repetitive work that were reversal to adaptations reported with exercise training. Progress has been made in developing intelligent physical exercise training, IPET, as the best complementary activity to job exposure and includes muscle activations and movements that limit work-related inactivity atrophy as well as overload injury.

众所周知，体育活动有益于健康，而在职业工作期间进行的肌肉活动和运动相反可能会导致与工作相关的肌肉骨骼疾病。因此，我们提出了一个研究问题：哪种肌肉激活模式可能会导致与工作相关的障碍的逆转？为了解决这个问题，我们对具有不同暴露类别的工人进行了肌电图 (EMG) 和运动学评估：久坐单调的工作、长时间行走/站立和体力繁重的工作。各种特定于工作的暴露变量可以根据持续时间、强度、重复、静态分量、峰值力等进行分类，这些变量随后被确定为风险因素。根据运动科学原理，我们制定了量身定制的锻炼计划，以抵消工作风险。监测运动训练期间的肌电图活动，以确定运动训练和工作模式之间的主要差异。来自包括 4000 多名工人在内的 20 多项 RCT 研究的证据显示出积极的效果，例如减少肌肉疼痛和提高工作能力。最后，我们确定了肌肉组织（人和动物）中看似合理的潜在机制，这些机制证实了代谢、形态和荷尔蒙的变化，例如重复性工作与运动训练报告的适应性相反。在开发智能体育锻炼训练方面取得了进展，IPET，作为工作接触的最佳补充活动，包括肌肉激活和运动，以限制与工作相关的不活动萎缩和超负荷损伤。
