This is a cross-sectional study that examined the association between fitness trainers’ educational qualifications and experience, and the risk of their trainees’ musculoskeletal pain. The study included 1177 trainees (aged 15−60 years) from 74 fitness centers in Bangladesh. Data were collected by using the Nordic musculoskeletal questionnaire, including potential confounders such as demographic factors (e.g., age, occupation), and training-related factors (e.g., workout knowledge, overweight lifting). Multiple logistic regression was performed for a binary outcome (pain—yes or no), and a generalized linear model was fitted for the ordinal outcome (pain—sites of the body). The trainers’ lower experience (no or ≤1 year) was associated with higher odds of their trainees’ musculoskeletal pain (OR: 2.53, 95% CI: 1.18−5.44) compared to trainers with >5 years of experience; however, no association was found between the trainers’ education and the risk of their trainees’ musculoskeletal pain, after controlling for potential confounders. Similarly, the trainees trained by trainers with lower experience had more than two-time the risk of having pain in different sites (IRR: 2.04, 95% CI: 1.50−2.79). The trainers’ experience may play a pivotal role in the trainees’ musculoskeletal pain. Further study is warranted in this regard.
这是一项横断面研究，旨在探讨健身教练的教育资质与经验与其学员肌肉骨骼疼痛风险之间的关联。该研究纳入了来自孟加拉国74家健身中心的1177名学员（年龄在15至60岁之间）。通过使用北欧肌肉骨骼问卷收集数据，问卷包括潜在混杂因素，如人口统计学因素（如年龄、职业）和与训练相关的因素（如锻炼知识、超重举重）。对二元结局（疼痛——是或否）进行多元逻辑回归分析，并对有序结局（疼痛——身体部位）拟合广义线性模型。与经验超过5年的教练相比，经验较少（无经验或经验≤1年）的教练的学员发生肌肉骨骼疼痛的几率更高（比值比：2.53，95%置信区间：1.18 - 5.44）；然而，在控制潜在混杂因素后，未发现教练的教育程度与其学员肌肉骨骼疼痛风险之间存在关联。同样，由经验较少的教练培训的学员在不同部位疼痛的风险是其他人的两倍多（发病率比值比：2.04，95%置信区间：1.50 - 2.79）。教练的经验可能在学员的肌肉骨骼疼痛中起关键作用。在这方面有必要进行进一步研究。
