Correlation of Knowledge and Attitude towards Exercise Habbit Action in FK USU Student

Background : Sport is a physically demanding activity that has a positive impact on the body. Exercise, in addition to maintaining physical fitness and being useful to one's health, it may protect a person from negative things such as stress and can be utilized as a kind of leisure. However, there are still many people who do not exercise properly. It is not necessarily excellent exercise for those who have good exercise knowledge, and it is not necessarily poor exercise for people who have less exercise knowledge. Exercising also disregards a person's age; people of all ages, young and old, are allowed to participate in sports they enjoy, such as aerobic and anaerobic activities. As previously said, in addition to maintaining physical fitness and being helpful to one's health, students should exercise to relieve tension induced by lectures. However, many students are overworked and do not consider exercise to be vital because they do not have spare time to participate in sports. Students will become unfit and unable to concentrate on the lecture subject as a result of this. Purpose : This study aims to determine whether there is a correlation between knowledge and attitudes towards the habit of exercising in students of the Faculty of Medicine, Universitas Sumatera Utara. Method : The research that will be conducted is an observational analytic study with a cross-sectional study approach. The sample to be studied in this study was 260 students of the Faculty of Medicine, Universitas Sumatera Utara who met the inclusion criteria. The data used is primary data that will be obtained from questionnaires filled out online through the Line, WhatsApp, and Instagram applications. Results : Based on the data obtained using the chi-square method, then the results obtained were p = 0.202 and p = 0.706 (p <0.05). Conclusion : Based on these results, H o is accepted, so there is no correlation between knowledge and attitudes towards the habit of exercising in USU Medical Faculty students.


Introduction
Exercise is a requirement that cannot be overlooked. Exercise is a type of physical exercise that involves the movement of the body. It is intended that by exercising, a person will have a healthy and fit body that will help them be more productive in their daily lives. If a person isn't in good physical shape, it's safe to assume that his or her productivity will suffer. [3] According to the national Basic Health Research (RISKESDAS) in 2018, the proportion of people aged 10 and above in North Sumatera who are less active in physical activity is 33,7%. [7] Medan, with a rate of 46.95%, is the district or city with the lowest level of physical activity. Dairi, with a proportion of 85.56%, is the most active city or district in North Sumatera in terms of physical activity. [6] Adults should exercise for 150 minutes each week, according to the Physical Activity Guidelines for Americans, and people who exercise consistently have a better quality of life. If someone wants to do high-intensity exercise, they should do it for at least 75 minutes every week. [8] Students, as the driving force behind national transformation, play a critical role in nation-building. As a result, students must meet certain criteria in order to affect the destiny of their countries, one of which is that they must be healthy and fit. Physical activity or exercise will result in a fit and healthy body. According to Alfian research [1], students' busy schedules have a significant impact on physical activity, reducing their awareness of the need to exercise. The enormous study load each day, as well as the chores that must be accomplished, have an impact on this. This is also corroborated by the findings of a study by Wahyudi [9], which found that out of 166 students at the University of Riau's Faculty of Medicine, just 30 (18,7%) conduct exercise regimens. This is due to the fact that medical students have hectic schedules and little leisure time.

It reveals that out of 260 responders, 54 have taken poor action (20.8%), 130 have taken sufficient action (50%), and 76 have taken good action (29.2%). Then, out of 260 respondents, it was discovered that 57 had poor knowledge (21.9%), 139 had sufficient knowledge (53.5%), and 64 had good knowledge (24,6%). Table 4.8 also shows that among the 54 respondents who took insufficient action, 15 had insufficient knowledge (5.8%), 30 had sufficient knowledge (11.5%), and 9 had good knowledge. 3.5%. There are 130 people who have taken adequate action. There are 31 people who have a poor degree of knowledge (11.9%), 68 people who have a sufficient level of knowledge (26.2%), and 31 people who have a good level of knowledge (11.9%). 76 people responded with positive behaviors. There are 11 people with a poor level of knowledge (4.2%), 41 people with a sufficient level of knowledge (15.8%), and 24 people with a good level of knowledge (2.4%). (9.2%).
It reveals that out of 260 responders, 54 have taken poor action (20.8%), 130 have taken sufficient action (50%), and 76 have taken good action (29.2%). Then, out of 260 respondents, it was discovered that 6 had a poor attitude (2.3%), 85 had a sufficient attitude (32.7%), and 169 had a good attitude (65%).

Using the chi-square approach, researchers discovered that there was a difference in the association between knowledge and attitudes toward the practice of exercising habits in Faculty Of Medicine Universitas Sumatera Utara , with knowledge having a p value of 0.202 and attitude having a p value of 0.706 (p 0.05). According to these findings, there is no correlation between knowledge and attitudes about the exercise habit.

Discussion
In the preceding discussion, it was discovered that there was no correlation between knowledge and action, with a p value of 0.202, and that there was a p value of 0.706 for the correlation between attitudes and actions. Because H o is accepted because the p value is less than 0.05, it may be assumed that there is no correlation between knowledge and attitudes about exercising in FK USU students. This is similar to previous studies, such as Febrianto [2] , The Relationship Between Knowledge and Attitude with Exercise Habits at Al-Quran Al-Amin Islamic Boarding School Santri Purwokerto, which found no relationship between knowledge and habits (p = 0.124) and a correlation between attitude and exercise habits (p = 0.756). Hidayati [5] [4] also mentioned that there is no correlation between knowledge and attitudes toward exercise during pregnancy. In his research, he discovered that out of 50 persons, 29 (58%) had strong knowledge and 32 (64%) had a positive attitude, with a p value of 0.267. The benefit of this research is (1) For researchers, it can be seen that there is no correlation between knowledge, attitude, and habitual exercise in Faculty of Medicine Universitas Sumatera Utara so that it can be used as a basis for providing education in the future. It is hoped that future researchers will research this because there is still a lack of research available on this study.

Conclusion
The results were found to be p = 0.000 (p <0.05). Based on the results, the H 0 was agreed, so there was not a correlation between knowledge and attitude towards exercise habit action in FK USU students.
