目的是通过对13-14岁年龄组进行6年的反复研究，考虑到平行的国家体育教育（PE）趋势，确定中学生健康相关健身（HRF）的最新横截面趋势。从2014年到2019年，同一研究团队使用标准化技术测量了身高、体重、跳远、握力、20米穿梭跑和抛接球技能。这些HRF测量的趋势通过线性回归评估，调整学校、性别和身高。测试了与健康和身体质量指数（BMI）的相互作用。研究人员分析了2010年至2019年英国年度学校劳动力普查中报告的所有公立中学的体育课程数量。握力（B= - 0.60, 95% CI为- 0.78 ~ -0.41）、跳远（B= - 1.16, 95% CI为- 1.99 ~ -0.34）、20米短跑（B= - 1.85, 95% CI为- 2.58 ~ -1.12）、投掷和接球技能（B= - 0.12, 95% CI为- 0.15 ~ -0.08）在研究期间显著下降。健康水平低的青少年跳远和握力下降幅度更大，BMI正常的青少年健康和运动能力下降幅度更大。与此同时，2010年（33800小时）至2019年（280725小时）期间，全国中学体育课时减少了16%。近年来，青少年HRF下降，体育课程也在下降。在所有的年轻人中，尤其是那些健康状况不佳和BMI正常的年轻人，他们的体重都有所下降。为了接触到大多数年轻人，政策制定者可以增加学校的体育活动，以增加活动，防止后代的健身和健康状况恶化。
The objective was to determine recent cross-sectional trends in health-related fitness (HRF) in secondary school students by studying the 13–14 years old age group repeatedly over 6 years, considering parallel national trends in physical education (PE). Height, weight, broad jump, grip strength, 20 m shuttle run and throwing and catching skills were measured by the same research team using standardised techniques from 2014 to 2019. Trends in these HRF measures were assessed by linear regression, adjusting for school, sex and height. Interactions with fitness and body mass index (BMI) were tested. The number of PE lessons reported in the UK Annual School Workforce Census between 2010 and 2019 for all state-funded secondary schools was analysed. Grip strength (B=−0.60, 95% CI −0.78 to –0.41), broad jump (B=−1.16, 95% CI −1.99 to –0.34), 20 m shuttle run (B=−1.85, 95% CI −2.58 to –1.12) and throwing and catching skills (B=−0.12, 95% CI −0.15 to –0.08) declined significantly over the study period. There was a greater reduction in broad jump and grip strength in adolescents with low fitness and a greater reduction in fitness and motor competence in adolescents with normal BMI. These declines coincided with a 16% reduction nationally in secondary school PE between 2010 (333 800 hours) and 2019 (280 725 hours). Adolescent HRF has declined in recent years, in parallel with PE lessons. Declines were observed across all young people and particularly those of low fitness and normal BMI. To reach the majority of young people, policy makers could increase PE in schools to increase activity and prevent worsening fitness and health in future generations.
