肥胖干预并不是唯一的好处。许多研究确实指出了肥胖和健康干预之间的联系;然而，像哈里斯这样的研究指出，即使采取干预措施，减少肥胖也不会是主要的好处。对141名小学生进行的研究表明，当学校基础体育活动得到改善时，BMI没有变化(Harris et al, 2009, 719)。还有其他的健康益处，但是BMI和肥胖相关的健康益处没有得到显著的注意。比德尔等研究人员支持这一观点(比德尔2011,887)。从许多干预研究中可以观察到，如果身体活动得到了良好的提高，那么认知能力就有可能得到发展。提高认知能力和学习成绩是可能的。
Obesity intervention is not the only benefit. Many studies do point out the connection between obesity and health interventions; however, studies like Harris points out that even with intervention obesity reduction will not be the major benefit. Studies conducted on 141 elementary school children revealed that BMI did not change when school based physical activity was improved (Harris et al 2009, 719). There were other health benefits, but BMI and obesity related health benefits were not significantly noticed. Researchers like Biddle support this argument (Biddle 2011, 887). It was observed from many intervention studies that where physical activity is improved on a good level, then it would be possible for there to be cognitive development. Improved cognitive performance and academic achievement are possible.
Once again, limitations exist. Researchers like Stuart for instance argue that there is evidence to show that physical activity and mental health are connected, but research designs are often quite weak and hence the associations are presented as small to moderate. However, despite the levels of significance, the consistency presented in such associations argues the case.
The studies analysis shows that there is a definite need to improve the quality of PE in secondary schools in order to help assist students in controlling obesity and for other health benefits. Teachers could be successful agents of change when it comes to initiating such PE actions School curriculum will need to be improved as well. School professionals must be brought up to date as specialists advocating change in PE. This would ensure maximum benefits are reaped.
Having PE classes alone did not improve health quality. According to researchers like students who were in classes that were led by specialists in health care seemed to be reaping more health results than students in control classes. Health related physical educations taught by health education specialists, hence were observed to reap the most benefits. Therefore, physical education classes when augmented with specific health focus and related activities could lead to much more benefits for the students。
