This survey assessed the knowledge of the "Guidance for prescribing exercise" issued by the American College of Sports Medicine (ACSM) in 2011 among certified exercise professionals. A sample of 1,808 certified exercise professionals (66.70% women, mean (± SD) age = 38.28 ± 12.56 years) responded to electronic invitations. The 11-question online questionnaire assessed knowledge of the recommended frequency, duration, and intensity ranges in terms of heart rate, metabolic equivalents, and ratings of perceived exertion. Respondents had 7.45 ± 8.07 years of work experience and represented all 50 U.S. states. On average, participants answered 42.87 ± 1.69% of the questions correctly. Gender, age, and years of professional experience were not associated with overall knowledge of the guidelines. Likewise, having 1, 2, or 3+ certifications made no difference in overall knowledge. However, there were significant differences between levels of education (F = 7.12, p < 0.001), from 38.72 ± 1.62% for "some college" to 47.01 ± 1.71% for "doctorate." There were also significant differences by primary job role (F = 3.45, p < 0.001) but no category exceeded 49% (e.g., personal trainers: 40.59 ± 1.66%; clinical exercise physiologists: 44.18 ± 1.70%). The respondents rated their knowledge of the exercise prescription guidelines as 7.01 ± 1.69 of 10 but rated the level of knowledge necessary to practice safely and effectively as 8.32 ± 1.64 (t = 28.60, p < 0.001). This survey, the first at this scale to investigate the knowledge of exercise prescription guidelines among certified exercise professionals, showed that there is room for improvement, considering that the average score was below 50%.
这项调查评估了认证运动专业人员对美国运动医学学院（ACSM）2011年发布的《运动处方指南》的了解情况。1808名认证运动专业人员（66.70%为女性，平均（±标准差）年龄 = 38.28 ± 12.56岁）回复了电子邀请函。这份包含11个问题的在线问卷评估了在心率、代谢当量和自觉用力程度方面推荐的运动频率、时长和强度范围的相关知识。受访者有7.45 ± 8.07年的工作经验，来自美国所有50个州。平均而言，参与者正确回答了42.87 ± 1.69%的问题。性别、年龄和专业工作年限与对指南的总体了解无关。同样，拥有1项、2项或3项以上认证在总体知识方面没有差异。然而，教育水平之间存在显著差异（F = 7.12，p < 0.001），“部分大学学历”的正确率为38.72 ± 1.62%，“博士学历”的正确率为47.01 ± 1.71%。主要工作岗位也存在显著差异（F = 3.45，p < 0.001），但没有一个类别超过49%（例如，私人教练：40.59 ± 1.66%；临床运动生理学家：44.18 ± 1.70%）。受访者对运动处方指南知识的自我评分是7.01 ± 1.69（满分10分），但对安全有效实践所需知识水平的评分是8.32 ± 1.64（t = 28.60，p < 0.001）。这项调查是首次在如此大规模上调查认证运动专业人员对运动处方指南的知识，鉴于平均得分低于50%，表明仍有改进空间。
