A Dataset on Body Composition, Strength and Performance in Older Adults, Created from Rancho Bernardo Study

These data originated from Rancho Bernardo Study, a longitudinal observational cohort study. The study enrolled subjects between 1972 and 1974. A subset of the subjects returned every four years for subsequent visits. This dataset consists of raw measurements of body composition, strength and performance from Visits 7-10, as well as some secondary measurements computed from the raw measurements.本数据集源自兰乔伯纳多研究（Rancho Bernardo Study）——一项纵向观察队列研究。该研究于1972年至1974年间招募研究对象，其中部分受试者每四年回访一次，参与后续随访。本数据集涵盖第7至10次随访所采集的身体成分、肌肉力量与运动表现原始测量数据，以及部分由原始测量值计算得到的衍生测量指标。
