In this study, the absolute and relative strength of six upper extremity resistance exercises were measured by classifying resistance exercise experts and non-experts. As a result, the skilled group showed higher absolute and relative muscle strength than the unskilled group in the 6 upper extremity resistance exercises. These results are judged to be the hypertrophy of fast-twith muscles, the mobilization of motor units, and the increase in the speed of nerve conduction while the skilled person consistently performs resistance exercise. Experts use intermuscular coordination efficiently to stably perform the load according to the movement and exercise intensity performed during exercise, whereas the inexperienced person uses relatively large muscle groups rather than efficiently using intermuscular coordination. It is considered that exercise motion and load were performed by mobilizing. In addition, as a result of comparing the absolute and relative muscle strength between the 6 types of upper limb resistance exercises, there was a difference between the 6 types of upper limb resistance exercises in the two groups. It can be judged that greater muscle strength and endurance were created through liver coordination.

This article a little bit lack of elements for the basis of study of health care in the respect of taking a certain expert group as the sample. However researcher chose people who is in same situation with himself and tried to make clear how to do for their behavior of health care to know that how the experts groups are taking care of their health. For the study, the main aim of this article is studying the health care situation of experts group which is taking crucial role in the economy, society and cultural field. When it comes to the experts group's health care by eating habits and exercise related program is, first, it indicates that most people are eating for their health, lives and work through the analysis of responds; they eat food for their health and their health, lives or task.(Surely they family-centered structure. Third, 78% of 40s group responded that they enjoy finding good restaurants while 20s to 30s are enjoying fastfood and instant food instead of Korean traditional foods. fourth, health care by the exercise is done in one or half one hour and the dependant exercises like jogging or swimming which can be done whenever they have time are perferred to group exercise. It's desirable that one has to take care of himself with systematic and effective way. But it's very difficult and care for most people to take care of themselves, so they have to make the program and practice it systematically. The result from this study shows that practicing the health related program rationally, at the same time increasing leisure time and doing dependant or group exercise, taking a walk, and various kind of exercise considered spending money are more common than eating foods for health care. These are regarded as a desirable phenomenon in terms of the health care.

Purpose: Since coronavirus disease 2019 (COVID-19) spread around the world, non-face-to-face services have emerged as the new normal. The functioning of children with developmental disabilities and cerebral palsy improves when parents, therapists, and institutions cooperate. We aimed to investigate the difficult environment of pediatric physical therapy caused by COVID-19, and grasp parents' perceptions of home exercise programs. We intend to design home exercise programs for pediatric treatment in the future and create a non-face-to-face pediatric rehabilitation service system based on our findings. Methods: The first survey was conducted on 30 parents who had children with cerebral palsy and developmental disabilities. It was produced after consultation with relevant experts and discussion with the research team, based on a survey conducted in a previous study. The second survey was produced by revising and supplementing the opinions of parents who completed the first survey and consulting experts. Thereafter, an online survey was conducted on 118 parents who had children with cerebral palsy and developmental disabilities. Results: 61.01 % of the parents reported that they were anxious or afraid for their children to be treated for infectious diseases. 83.90 % of the parents reported that the role of parents had increased. 50.00 % of the parents complained of a lack of skill. 85.59 % of the parents reported that they needed a home exercise program provided by the organization. As a non-face-to-face exercise management method, 35.59 % of the parents wanted a real-time video recording electronically mailed to them, and 34.75 % wanted real-time education using video conferencing programs such as zoom. Conclusion: The threat of COVID-19 has further emphasized the importance of social cooperation and management, leading organizations to enter a new era of non-face-to-face rehabilitation services. It is necessary to collect and systematize related studies to reflect more diverse opinions and improve the perceptions of therapists and parents.

Purpose: This pilot study aimed to clarify features of motor module during walking in exercise experts who experienced lately repeated training for sports skill. To identify motor modules, autoencoder machine learning algorithm was used, and modules were extracted from muscle activities of lower extremities. Research design, data and methodology: A total of 10 university students were participated. 5 students did not experience any sports training before, and 5 students did experience sports training more than 5 years. Eight muscle activities of dominant lower extremity were measured. After modules were extracted by autoencoder, the numbers of modules and spatial muscle weight values were compared between two groups. Results: There was no significant difference in the minimal number of motor modules that explain more than 90% of original data between groups. However, in similarity analysis, three motor modules were shown high similarity (r>0.8) while one module was shown low similarity (r<0.5). Conclusions: This study found not only common motor modules between exercise novice and expert during walking, but also found that a specific motor module, which would be associated with high motor control ability to distinguish the level of motor performance in the field of sports.

In this study, joint angles of the lower extremity and inertial sensor data such as accelerations and angular velocities were measured during a ski simulator exercise in order to evaluate the skill of skiers. Twenty experts and twenty unskilled skiers were recruited for the study. All expert skiers held the certificates issued by the Korea Ski Instructors Association. A three-dimensional motion capture system and two inertial sensors were used to acquire joint movements, heel acceleration and heel angular velocity during ski simulator exercises. Pattern variation values were calculated to assess the variations in ski simulator motion of expert and unskilled skiers. Integral ratio of roll angular velocity was calculated to determine the parallel alignment of the two feet. Results showed that ski experts showed greater range of motion of joint angle, peak-to-peak amplitude(PPA) of heel acceleration and PPA of heel angular velocity than unskilled skiers. Ski experts showed smaller pattern variations than unskilled skiers. In addition, the integral ratio of roll angular velocity in ski experts was closer to 1. Inertial sensor data measurements during the ski simulator exercises could be useful to evaluate the skill of the skier.
