Klakk et al. conducted an intervention study by increasing the frequency of physical education lessons in children aged 8 to 13 years, and they examined its effect on body fat during two school years. Physical education has potential to provide health in childhood and adolescence. For achieving these benefits, one of the most relevant aspects that need to be addressed during physical education classes is to provide students with high levels of physical activity. A well-recognized recommendation suggests that students should engage in moderate to vigorous physical activity for at least 50% of the time they spend in physical education classes. Therefore, it would be crucial to know what is happening during physical education classes before increasing their frequency. On the other hand, it seems that the main concern of health-related researchers is provide evidence on the impact of physical education on physical health outcomes (e.g. obesity), whereas other dimensions of health such as social, emotional, intellectual, and spiritual health are understudied. New evidence on the role of physical education on other health outcomes beyond physical health would also be important for the recognition of this curricular subject.
克拉科等人进行了一项干预研究，增加了 8 至 13 岁儿童的体育课频率，并在两个学年内观察其对体脂肪的影响。体育课有可能为儿童和青少年提供健康。为了实现这些益处，在体育课中需要解决的最相关的方面之一是为学生提供高水平的身体活动。一项公认的建议是，学生应该在体育课上至少进行 50%的中等至剧烈身体活动。因此，在增加体育课的频率之前，了解体育课上正在发生的事情至关重要。另一方面，健康相关研究人员似乎主要关注的是提供有关体育课对身体健康结果（如肥胖）影响的证据，而其他健康维度，如社会、情感、智力和精神健康，则研究不足。关于体育课对身体健康以外的其他健康结果的作用的新证据，对于承认这一课程科目也很重要。
