: The present study aimed to investigate and compare physical activity (PA) and health-related fitness in Asian adolescents, and to examine the associations between meeting PA guidelines and attaining fitness standards. : A sample of 12,590 adolescents ( = 13.63 years, = 1.01) from eight Asian metropolitan cities completed measurements of PA, five field-based fitness tests, and covariates. The fitness test scores were further classified into Healthy Fitness Zone (HFZ) or Needs Improvement Zone (NIZ). : Findings showed that adolescents' levels of PA and fitness components differed by cities. City differences were also found in proportions of meeting PA guidelines and achieving the HFZs of aerobic capacity, muscular fitness, and body composition. After controlling covariates, meeting PA guidelines positively associated with being in the HFZs of aerobic and muscular fitness, but the association was not significant with being in the body composition HFZ. : There was a large variation in PA and health-related fitness in adolescents across the eight Asian cities. Asian adolescents achieving PA guidelines were more likely to be in the HFZ of aerobic and muscular fitness. Prospective follow-up studies are warranted to gain better insights into the relationships between objectively-measured PA and fitness.
本研究旨在调查和比较亚洲青少年的身体活动（PA）和与健康相关的体能，并探讨达到 PA 指南和达到体能标准之间的关联。
来自八个亚洲大都市的 12590 名青少年（=13.63 岁，=1.01）完成了 PA 测量、五项基于现场的体能测试和协变量的测量。进一步将体能测试得分分类为健康体能区（HFZ）或需要改进区（NIZ）。
研究结果表明，青少年的 PA 水平和体能成分因城市而异。在达到 PA 指南和达到有氧能力、肌肉力量和身体成分 HFZ 的比例方面也存在城市差异。在控制协变量后，达到 PA 指南与处于有氧和肌肉力量的 HFZ 呈正相关，但与处于身体成分 HFZ 的关联不显著。
在这八个亚洲城市中，青少年的 PA 和与健康相关的体能存在很大差异。达到 PA 指南的亚洲青少年更有可能处于有氧和肌肉力量的 HFZ。需要进行前瞻性随访研究，以更深入地了解客观测量的 PA 和体能之间的关系。
