This study investigated whether general intelligence could predict physical fitness and academic achievements one year later.
We recruited 129 Spanish adolescents (57.4% boys) with a mean age of 13.6 ± 0.7 years old from a convenience sample of a single public-funded school. The first step was to assess general intelligence during the 2015-2016 school year using the D48 nonverbal test. A year later, we collected data on fitness and academic achievements. Cardiorespiratory fitness was measured with the 20-m endurance shuttle run test, muscular strength with the standing long jump and flexibility with the sit and reach test. Academic achievement was measured using school grades. The findings were assessed using three models with different variables.
One year later, general intelligence at baseline was marginally significantly associated with flexibility (p = 0.079) and mathematics (p = 0.084) in the first model, with mathematics (p = 0.029) and geography and history (p = 0.016) in the second model and with geography and history (p = 0.022) in the third model. All the analyses were controlled by age, sex, fitness and academic achievement.
General intelligence may not predict fitness, but it may predict academic achievements in adolescents one year later. Further studies are needed to examine our findings.
本研究旨在探讨一般智力是否能预测一年后的身体健康和学业成绩。
我们从一所公立学校的便利样本中招募了 129 名西班牙青少年（57.4%为男性），平均年龄为 13.6±0.7 岁。第一步是在 2015-2016 学年使用 D48 非言语测试评估一般智力。一年后，我们收集了有关体能和学业成绩的数据。心肺功能是通过 20 米耐力穿梭跑测试来测量的，肌肉力量是通过立定跳远来测量的，柔韧性是通过坐立前伸测试来测量的。学业成绩是用学校成绩来衡量的。研究结果使用三种不同变量的模型进行评估。
一年后，基线时的一般智力与灵活性（p=0.079）和数学（p=0.084）在第一个模型中，与数学（p=0.029）和地理与历史（p=0.016）在第二个模型中，与地理和历史（p=0.022）在第三个模型中均有边缘显著相关。所有分析均控制了年龄、性别、体能和学业成绩。
一般智力可能无法预测身体健康，但它可能可以预测一年后青少年的学业成绩。需要进一步的研究来检验我们的发现。
