For the scientific domain of physical activity and public health research to advance its agenda of health promotion and disease prevention continued development of measurement methodologies is essential. Over the past 50 years most data supporting a favorable relationship between habitual physical activity and chronic disease morbidity and mortality have been obtained using self-report methods, including questionnaires, logs, recalls, and diaries. Many of these instruments have been shown to have reasonable validity and reliability for determining general type, amount, intensity, and bout duration, but typically do better for groups than individuals with some instruments lacking the sensitivity to detect change in activity. During the past decade the objective assessment of physical activity using accelerometer-based devices has demonstrated substantial potential, especially in documenting the pattern of light-, moderate-, and vigorous-intensity activity throughout the day. However, these devices do not provide information on activity type, location or context. Research that combines the strengths of both self-report and objective measures has the potential to provide new insights into the benefits of physical activity and how to implement successful interventions.
为了推动体育活动和公共健康研究领域的议程，促进健康和预防疾病，持续发展测量方法至关重要。在过去的 50 年中，大多数支持习惯性体育活动与慢性病发病率和死亡率之间存在有利关系的数据都是通过自报方法获得的，包括问卷、记录、回忆和日记。这些工具中的许多已经被证明对于确定一般类型、数量、强度和持续时间具有合理的有效性和可靠性，但通常在群体中比个体更有效，有些工具缺乏检测活动变化的敏感性。在过去的十年中，使用基于加速度计的设备对体育活动进行客观评估已经显示出了巨大的潜力，尤其是在记录全天的低强度、中强度和高强度活动模式方面。然而，这些设备无法提供有关活动类型、地点或背景的信息。将自报和客观测量的优势相结合的研究有可能为体育活动的益处以及如何实施成功的干预措施提供新的见解。
