It is thought by some that having sport as a subject is not appropriate for schools in terms of time and resources, whereas the opponents of this idea take the view that this subject plays a pivotal role in the teaching process. Although the former concept can be true in some conditions as not all students have an interest in sports,and they prioritise the importance of other core lessons, and not all schools can afford to supply the whole pupils with quality facilities, I would argue that sport has crucial effects on students' physical development and releasing their stress.
