将行为支持干预广泛地纳入运动试验，有时会导致人们对试验的主要目的感到困惑。本文的目的是提供三种类型的运动试验之间的一些概念和方法上的区别，以期改进它们的设计、实施、报告和解释。根据运动试验的主要结果，可将其分为“健康结果试验”或“行为改变试验”。根据传播到实践中的潜力，健康结果试验可进一步分为疗效试验和有效性试验。运动效能试验可通过在短干预期内监督运动(“传统”运动效能试验)或通过采用广泛的行为支持干预措施来实现高水平的运动依从性(“当代”运动效能试验)，该干预措施旨在适应无人监督的运动和/或延长的干预期。运动有效性试验可能源于对具有已证实有效性的运动干预措施进行测试的愿望(“传统”运动有效性试验)或对具有已证实可行性的行为支持干预措施进行测试的愿望(“当代”运动有效性试验)。有效性、有效性和行为改变试验在主要和次要结果、采用的理论模型、参与者的选择、锻炼和比较干预的性质、行为支持干预的性质、样本量计算和对试验结果的解释方面往往不同。鼓励运动研究人员澄清他们试验的主要目的，以促进试验的设计、实施和解释。
The widespread incorporation of behavioral support interventions into exercise trials has sometimes caused confusion concerning the primary purpose of a trial. The purpose of the present paper is to offer some conceptual and methodological distinctions among three types of exercise trials with a view towards improving their design, conduct, reporting, and interpretation. Exercise trials can be divided into "health outcome trials" or "behavior change trials" based on their primary outcome. Health outcome trials can be further divided into efficacy and effectiveness trials based on their potential for dissemination into practice. Exercise efficacy trials may achieve high levels of exercise adherence by supervising the exercise over a short intervention period ("traditional" exercise efficacy trials) or by the adoption of an extensive behavioral support intervention designed to accommodate unsupervised exercise and/or an extended intervention period ("contemporary" exercise efficacy trials). Exercise effectiveness trials may emanate from the desire to test exercise interventions with proven efficacy ("traditional" exercise effectiveness trials) or the desire to test behavioral support interventions with proven feasibility ("contemporary" exercise effectiveness trials). Efficacy, effectiveness, and behavior change trials often differ in terms of their primary and secondary outcomes, theoretical models adopted, selection of participants, nature of the exercise and comparison interventions, nature of the behavioral support intervention, sample size calculation, and interpretation of trial results. Exercise researchers are encouraged to clarify the primary purpose of their trial to facilitate its design, conduct, and interpretation.
