To assess effects of 1-year Intelligent Physical Exercise Training (IPET) on musculoskeletal health.
Office workers were randomized 1 : 1 to a training group, TG ( = 193), or a control group, CG ( = 194). TG received 1 h supervised high intensity IPET every week within working hours for 1 year and was recommended to perform 30 min of moderate intensity physical activity for 6 days a week during leisure. The IPET program was based on baseline health measures.
No baseline differences were present. An intention-to-treat analysis showed significant between-group effect for muscle strength but not for musculoskeletal pain. However, a per-protocol analysis of those with an adherence of ≥70% demonstrated a significant between-group effect for neck pain during the past three months. Several significant within-group changes were present, where TG and TG ≥ 70% demonstrated clinically relevant pain reductions whereas minimal reductions were seen for CG.
IPET and recommendations of moderate intensity physical activity demonstrated significant between-group effect on muscle strength. Interestingly, significant within-group reductions in musculoskeletal pain were seen not only in TG but also in CG. This may underlie the lack of such between-group effect and shows that a possible positive side effect of merely drawing attention can improve musculoskeletal health.
评估为期 1 年的智能体能训练（IPET）对肌肉骨骼健康的影响。
将上班族随机分为训练组（TG，n=193）和对照组（CG，n=194），1:1 比例。TG 每周在工作时间内接受 1 小时监督的高强度 IPET，并被建议在闲暇时间每周进行 6 天、每次 30 分钟的中等强度体育活动。IPET 方案基于基线健康指标。
无基线差异。意向性治疗分析显示，肌肉力量存在显著的组间效应，但肌肉骨骼疼痛无显著的组间效应。然而，对≥70%依从性者的方案分析显示，过去 3 个月的颈痛存在显著的组间效应。几个组内变化有显著差异，TG 和 TG≥70%的组显示出有临床意义的疼痛减轻，而 CG 的疼痛减轻则较少。
IPET 和中等强度体育活动的建议对肌肉力量显示出显著的组间效应。有趣的是，不仅在 TG 组，而且在 CG 组中也观察到肌肉骨骼疼痛的显著组内降低。这可能是组间无差异的原因，并表明仅仅引起注意就可能对肌肉骨骼健康产生积极的副作用。
