Good physical health and capacity is a requirement for offshore wind service technicians (WTs) who have substantial physical work demands and are exposed to numerous health hazards. Workplace physical exercise has shown promise for improving physical health and work ability among various occupational groups. Therefore, we aimed to assess the feasibility and preliminary efficacy of Intelligent Physical Exercise Training (IPET) among WTs in the offshore wind industry.
A within-subject design was used to assess the feasibility and preliminary efficacy of IPET (one hour/week individualized exercise during working hours). The intervention period was 12 weeks, with the first eight weeks performed on site as supervised or partly supervised exercise during work hours and the last four weeks planned as home-administered exercise after the seasonal offshore service period. Three assessments, T1 (six months prior to intervention start), T2 (start of intervention) and T3 (end of intervention), of physical health and capacity (self-reported and objective measurements) were conducted and the period between T1 and T2 served as a within-subject control period. Primary outcome was feasibility measured as compliance, adherence, adverse events, and participant acceptability. Descriptive statistics were used to present feasibility outcomes. Preliminary efficacy was reported as mean differences with 95% confidence intervals for health and physical capacity outcomes between T1 and T2, between T2 and T3 and between T1 and T3.
All WTs at the included wind farm (n=24, age: 40 years (SD±8)) participated in the study. No serious adverse events were reported. Compliance and adherence of 95 and 80% respectively, were reached in the eight-week supervised part, but were lower when exercise was home-administered (<20%). Acceptability was high for the supervised part, with 83% indicating that the exercise program worked well and 100% that exercise should be implemented as an integrated part of the working structure. Changes in physical capacity and health indicators, such as VOmax (ml O/kg/min) at T1 (38.6 (SD±7.2)), T2 (44.1 (SD±9)) and T3 (45.8 (SD±6.5)), may indicate seasonal fluctuations as well as improvements from the intervention.
On-site Intelligent Physical Exercise Training during working hours was feasible and well received among WTs in the offshore wind industry. The proceeding of larger-scale evaluation and implementation is therefore recommended.

良好的身体健康和体能是海上风电运维技术人员（WTs）的必备条件，他们面临大量体力工作需求，且暴露于众多健康危害之中。工作场所的体育锻炼已显示出有望改善各类职业群体的身体健康和工作能力。因此，我们旨在评估智能体育锻炼训练（IPET）在海上风电行业WTs中的可行性和初步效果。
采用受试者内设计来评估IPET（工作时间内每周1小时个性化锻炼）的可行性和初步效果。干预期为12周，前八周在现场进行，工作时间内为监督或部分监督的锻炼，最后四周计划在季节性海上服务期后作为家庭锻炼。对身体健康和体能（自我报告和客观测量）进行了三次评估，即T1（干预开始前六个月）、T2（干预开始时）和T3（干预结束时），T1和T2之间的时间段作为受试者内对照期。主要结果是通过依从性、坚持性、不良事件和参与者可接受性来衡量的可行性。描述性统计用于呈现可行性结果。初步效果报告为T1与T2之间、T2与T3之间以及T1与T3之间健康和体能结果的平均差异及95%置信区间。
纳入风电场的所有WTs（n = 24，年龄：40岁（标准差±8））均参与了该研究。未报告严重不良事件。在为期八周的监督部分，依从性和坚持性分别达到了95%和80%，但当锻炼为家庭锻炼时则较低（<20%）。监督部分的可接受性较高，83%的人表示锻炼计划效果良好，100%的人表示锻炼应作为工作结构的一个组成部分实施。身体能力和健康指标的变化，如T1（38.6（标准差±7.2））、T2（44.1（标准差±9））和T3（45.8（标准差±6.5））时的最大摄氧量（ml O/kg/min）变化，可能表明存在季节性波动以及干预带来的改善。
工作时间内的现场智能体育锻炼训练在海上风电行业的WTs中是可行的且受到好评。因此建议进行更大规模的评估和实施。
