In addition to the benefits on physical and mental health, cardiorespiratory fitness has shown to have positive effects on cognition. This study aimed to investigate the relationship between cardiorespiratory fitness and body weight status on academic performance among seventh-grade students.
Participants included 1531 grade 7 students (787 male, 744 female), ranging in age from 12 to 14 years (Mage = 12.3 ± 0.60), from 3 different cohorts. Academic performance was measured using the marks students had, at the end of their academic year, in mathematics, language (Portuguese), foreign language (English), and sciences. To assess cardiorespiratory fitness the Progressive Aerobic Cardiovascular Endurance Run, from Fitnessgram, was used as the test battery. The relationship between academic achievement and the independent and combined association of cardiorespiratory fitness/weight status was analysed, using multinomial logistic regression.
Cardiorespiratory fitness and weight status were independently related with academic achievement. Fit students, compared with unfit students had significantly higher odds for having high academic achievement (OR = 2.29, 95% CI: 1.48-3.55, p < 0.001). Likewise, having a normal weight status was also related with high academic achievement (OR = 3.65, 95% CI: 1.82-7.34, p < 0.001).
Cardiorespiratory fitness and weight status were independently and combined related to academic achievement in seventh-grade students independent of the different cohorts, providing further support that aerobically fit and normal weight students are more likely to have better performance at school regardless of the year that they were born.
除了对身心健康有益外，心肺适能已被证明对认知有积极影响。本研究旨在调查七年级学生的心肺适能和体重状况与学业成绩之间的关系。
参与者包括来自3个不同队列的1531名七年级学生（787名男性，744名女性），年龄在12至14岁之间（平均年龄=12.3±0.60岁）。学业成绩通过学生在学年末数学、语言（葡萄牙语）、外语（英语）和科学课程的成绩来衡量。为评估心肺适能，使用了来自Fitnessgram的渐进式有氧心血管耐力跑作为测试项目。使用多项逻辑回归分析学业成绩与心肺适能/体重状况的独立及联合关联。
心肺适能和体重状况与学业成绩独立相关。与不适能的学生相比，适能的学生取得高学业成绩的几率显著更高（比值比=2.29，95%置信区间：1.48-3.55，p<0.001）。同样，体重正常也与高学业成绩相关（比值比=3.65，95%置信区间：1.82-7.34，p<0.001）。
心肺适能和体重状况与七年级学生的学业成绩独立且联合相关，与不同队列无关，进一步支持了无论出生年份如何，有氧适能且体重正常的学生在学校更有可能取得更好成绩的观点。
