Purpose: In this study, the importance of exercise as an alternative to active health behaviors in the era of living with Coronavirus, the role of exercise science and the future of development were discussed based on previous studies. Method: For this study, previous studies were searched and analyzed. The databases of PubMed and KCI were searched by combining keywords such as Covid-19, exercise science, health, and evidence-based. Then classified and systematically analyzed according to the purpose of the study. Results: For exercise science to play a pivotal role in the era of COVID-19, first, conceptual development and establishment of exercise medicine based on scientific evidence, and at the same time constructing and DB of a lot of high-quality data, are based on the development of an education-field link platform that leads to the field. It will require development and application. The second is the active use of remote systems using various IT technologies that have recently been developed. Efforts are needed to preoccupy a theoretical and technological edge in the expanding market by actively utilizing XR beyond VR and AR in connection with the metaverse. Actual outcomes should be derived from this goal, so that they may be felt by many people, through activating practical convergence with various academic fields. Furthermore, it is critical to develop appropriate abilities through education and actively promote developed technologies or ideas such that body system activation through exercise is an important means of protecting the human body against various infections. Conclusion: Exercise science will be able to play a significant role in the creation of new values and developments in people’s perceptions, improving competency, and assuming responsibility for one’s own health in the post-COVID-19 era when it achieves that level of expertise and development.

The purpose of this study was to investigate what relationship there was among the level of satisfaction with the factors of the driving range user`s personality traits and consumption characteristic, and the intention to revisit to the driving range. For this purpose, 330 subjects were sampled from the users of outdoor driving ranges located in Seoul and Gyeonggi-do Province, and the questionnaire used by previous studies was corrected and complemented to suit the accomplishment of this study as the research instrument. Collected data were analysed using SPSS 12.0 statistical package and the test was conducted at a level of α=.05 through correlation analysis and analysis of variance in case there was a significant difference according to the purpose of research. The following conclusion was concluded: 1) There was no significant correlation between the Driving range user`s personality traits and consumption characteristic and total level of satisfaction. Such factors as golfing experiences, age, frequency of use and behavior of use did not have an effect on the user`s total level of satisfaction. 2) There was not significant correlation between the user`s personality traits and consumption characteristic and intention to revisit the driving range. Such factors as golfing experiences, age, frequency of use and behavior of use did not exert an effect on the user`s intention to revisit the driving range.

The purpose of this study was to inquire educational meanings of overseas field exercise on the assumption that overseas field exercise for amateur golfers is one of educational phenomena. The results could be summarized as follow: First, according to guidance instructor, the educational purpose is to `cultivate learners of self-initiative.` The guidance instructors were in agony regarding education, and those agonies became strategies of teaching self-initiative in details. The strategies of teaching self-initiative were the center of attention in this study. It was observed from the perspective that emphasizing `put a vision into practice.` In addition, the golfers had various feelings, and they kept reminding themselves `to learn more than` just skills, knowledge, or tournament tactics through the field exercises. Second, the activities and behaviors of guidance instructors during overseas field exercises were observed as teaching strategy in order for them to emphasize the meaning of self-initiative. Moreover, learners, on the other hand, also had their own studying strategies by experiencing the field: fun and duty.

The aim of this study was to investigate the age-related changes of MVF (maximal voluntary contraction force) and finger interaction indices such as finger force enslaving (FE: force production by unintended fingers during force production by task finger), force deficit (FD: force difference between single finger MVF and the force of the same finger in four- finger task), and force sharing (FS: percent contributions of individual finger forces to the total force in four- finger task). Children(n=25, 6-11 years) and young adults(n=8, 20-23 years) participated as subjects in this study. The subjects performed single-finger and four-finger maximal voluntary contraction tasks. During the tasks, the subjects inserted the distal phalanges of the right hand into thimbles affixed to small force sensors with 20° of flexion about the metacarpophalangeal joint and pressed the sensor(s) to produce their maximum isometric force. The results revealed that: 1) MVF increased with age, the steep of increasing slope(N/year) from regression analysis was greatest at four-finger task, then index & middle finger, ring, and little finger task in that order. 2) FE showed the tendency of decrease with age, however, there was no significant difference across age groups. 3) FD revealed the tendency of decrease at all finger tasks with age, however, index finger only showed significant decrease with age. 4) FS was different across task fingers(M > I > R > L). FS pattern of individual finger was very similar across all age groups. We conclude that the finger strength increases with age, however, finger interaction indices(FE and FD) show the tendency of decrease with age from 6 to 23 years. The sharing pattern of fingers appears to develop before 6 years of age.
