The main purpose of this study was to track the performance and health-related physical fitness of girls from Brazil's Cariri region. In the "Healthy Growth in Cariri Study", 294 girls from public and private schools were divided into four age cohorts--8, 10, 12, and 14 years--and followed for three consecutive years, with an assessment every 6 months. Shuttle run, hand grip, standing long jump, trunk lift, curl-up, 12-min run, and fatness were used to rate physical fitness performance and health-related components on each of six occasions. Tracking was done in a stepwise manner, using auto-correlation, by modelling the individual history of change in performance of each girl, and using Foulkes and Davies' γ-coefficient. SPSS 18.0 and TIMEPATH were used for data analysis. Auto-correlations evidenced low-to-moderate values in almost all components of performance and health-related physical fitness. Intra-individual tracking analysis showed large variation in all fitness components as a result of a wide spread in individual history of change in fitness performance. Population estimates of γ were low in all tests. Our results show low-to-moderate tracking of physical fitness components of girls. A wide range of intra-individual and inter-variability in fitness development was observed.
本研究的主要目的是追踪巴西 Cariri 地区女孩的表现和与健康相关的体能。在“Cariri 健康成长研究”中，将来自公立和私立学校的 294 名女孩分为四个年龄组（8、10、12 和 14 岁），连续三年进行随访，每 6 个月评估一次。使用往返跑、握力、立定跳远、躯干提升、仰卧起坐、12 分钟跑和肥胖来评估每个女孩在六次评估中的体能表现和与健康相关的各项指标。采用自相关的逐步跟踪方法，通过建立每个女孩的个体变化表现的模型，并使用 Foulkes 和 Davies 的γ系数，对个体的变化进行跟踪。使用 SPSS 18.0 和 TIMEPATH 进行数据分析。几乎所有的体能表现和与健康相关的体能指标的自相关值都处于低到中等水平。个体内跟踪分析表明，由于个体体能表现变化的个体历史差异较大，所有的体能指标都存在较大的个体内变异。所有测试的γ值都较低。我们的研究结果表明，女孩的体能指标存在低到中等的跟踪性。观察到了个体内和个体间的体能发展的广泛变异性。
