Introduction
Physical education (PE), including formal PE and extracurricular activities, is the foundation of mass physical education.PE attempts to help the young break their sedentary lifestyle in order to spend more time doing exercise and playing sports, thereby enhancing their physical fitness.This benefit can only be achieved when they sufficiently participate in regular physical activities [1], [2], [3].
In PE, it cannot fail to mention the significance of extracurricular sports as they make a large contribution to the complete school educational system.Extracurricular sports or extracurricular activities, together with academic classrooms, parallelly exist to support and complement each other in order to optimize students' learning experiences.Therefore, it can be said that PE would not be satisfactorily completed without extracurricular sports [4], [5].
Another fact is that class time is not enough for learners to grasp all theories, hence, an extracurricular activity is carried out to offer them an opportunity to relate what they are taught to their real life.Such an activity helps them not only acquire knowledge but also develop their communication, problem-solving skills, and other necessary skills.This has led to more and more attention being paid to extracurricular activities, especially extracurricular sports today [6], [7], [8].
Extracurricular sports are physical activities that "match the interests, gender, age, and health of students", and are voluntary, organized, and conducted outside of regular school hours [9], [10].Participation in extracurricular activities is considered an important educational experience for learners (Cole, Rubin, Feild and Giles, 2007) [11], because through these activities they can practice their interpersonal skills (Rubin, Bommer and Baldwin, 2002) [12], leadership and social communication skills (Rynes, Trank, Lawson & Ilies, 2003) [13] to deal with their friends and solve problems occurring during the activities.Barnett (2007) describes an extracurricular activity as "... sports, academic clubs, student unions and special interest groups" [14].Fredricks and Eccles (2006) also suggest that "engaging in a satisfactory extracurricular sport is an effective use of leisure time..." [15].Therefore, it can be concluded that extracurricular sports are an extremely meaningful after-school activity where students can entertain and practice to increase their physical health and endurance.Given the subject's importance, our team managed to research on: "Extracurricular sports: popular contents and forms among students in the dormitory of Vietnam National University Ho Chi Minh City" The study aims to provide accurate information about the popular contents and forms to organize extracurricular sports at VNUHCMC dormitory.
