The purpose of this study is to confirm the effect of core training, resistance training, and flyometric combined exercise training of middle school soccer players on physical composition, physical strength, and functional movement, and further to study the continuity of such training. The 17 players training program to be conducted in this study was conducted for 90 minutes per 5 times a week for 8 weeks, and the details consist of 20 minutes of core training after 15 minutes of warm-up foam roller & mobility exercise, 45 minutes of weight training and flyometric training, and 10 minutes of cleanup foam roller & mobility exercise. Body composition, agility, muscle endurance, and functional movement tests were measured to verify the effectiveness of exercise. The analysis of the data obtained in this study was analyzed using the SPSS 25.0 statistical program, and the average (M) and standard deviation (SD) were calculated to present descriptive statistics of all dependent variables. One-way ANOVA repeated measure was conducted to verify the effectiveness of 8 weeks of complex training and 8 weeks of training maintenance for youth soccer players. At this time, the statistical significance level (α) in all reasoning statistics was set to less than 5%. As a result of studying the effect and continuity of exercise through eight weeks of combined exercise training for middle school soccer players, muscle mass and body fat rate showed a positive effect on continuity, and exercise continuity was presented in agility and agility. However, in the case of functional exercise tests, there was no positive effect and maintenance in items other than SM and ASLR, making it difficult to study the effectiveness of training in depth. Therefore, further research on the number and comparison group of study subjects will need to be reinforced in future studies, and further research on the effectiveness and continuity of complex exercise training after controlling additional variables of study subjects is highly related to injury experience and instability. Based on the results of this study, it is expected to be used as basic data for various complex exercise training studies for middle school athletes and help proceed with follow-up studies.

문황운,김준수 한국운동재활학회 2023 JER Vol.19 No.2

The purpose of this study was to evaluate the characteristics of golf-related musculoskeletal injuries. Golfers were retrospectively surveyed through a 50-item questionnaire. Golfers were divided into injured and noninjured groups according to the presence or absence of musculoskeletal injuries. Of the 208 respondents, 64.0% suffered golf-related injuries, most of which were minor injuries caused by overuse in the early 9.9 weeks. According to the anatomical distribution, the most injured parts were upper limbs, spine, trunk, and lower limbs in that order. As for the distribution by part, the hand and wrist were the most vulnerable, and the lateral elbow damage was 3 times more common than the inner elbow. Self-management for injuries was the most common treatment, and regular preventive exercise accounted for 30% of the injured. Overall, more than half of the respondents suffered from musculoskeletal injuries, self-management was the most common, and less than onethird did regular exercise to prevent injuries. Therefore, active management to prevent golf-related musculoskeletal injuries may be necessary.

The purpose of this study is to analyze the effectiveness of the automatic stepper and changes in lower extremity muscle activity through step by step exercise. The subjects were 18 male university students. Two groups of 9 students were made and they each proceeded 5 and 10 levels of automatic stepper exercise to analyze rectus femoris, biceps femoris, tibialis anterior and medial gastrocnemius. The analysis was used to find out the changes in lower extremity muscle activity using the EMG at 10, 20 and 30 minutes after the exercise. The mean and standard deviation of all data were calculated using the SPSS 24.0, and one-way ANOVA with repeated measure was performed to verify the difference in the mean between time periods for measurement variables. In the case of inter-period significance, the LSD method was used for the post-hoc test, and the statistical significance level was set to α=.05. In future research, an in-depth study of various variables through a regular exercise program for the elderly, disabled, and patients who need to exercise safely will be required.

The purpose of this study is to verify the effect of an automatic stepper that can be an easy exercise for the elderly who are experiencing difficulties in physical activity at a point in time when the need for exercise and reduction of physical activity in the elderly is being emphasized through COVID-19. The purpose of this study is to investigate the physiological changes of a sedentary automatic stepper through changes in energy consumption and changes in vascular elasticity variables. The subjects of this study were 8 male and 9 female aged 83 years old. 30 minutes of automatic stepper exercise was performed. Blood pressure, brachial-ankle pulse wave velocity, arterial stiffness and lactic acid were measured before and after exercise, and energy consumption was measured through heart rate, oxygen intake, METs, and cumulative calorie consumption before and during exercise for 10 minutes, 20 minutes and 30 minutes. The results of this study showed that systolic, diastolic, and mean blood pressure all decreased after exercise in the male elderly, but there was no statistically significant change. In addition, the cumulative calorie consumption of both male and female elderly increased statistically significantly(p<.000), but there was no significant change in the vascular elasticity variable. This study tried to examine whether the effect of automatic stepper exercise can be applied to the elderly male and female, but only showed a significant increase in the cumulative energy consumption. In addition, changes in vascular elasticity were examined, but exercise intensity was low, and it was difficult to study vascular elasticity by sitting and continuing topical exercise. In future research, it is considered that it is necessary to develop an automatic stepper exercise program suitable for various subjects, such as the elderly, the disabled, and patients who need to exercise safely, and to examine the effect in depth with various variables.

We are generally believed that optimal muscular function and hypertrophy gains are induced via moderate- or high-intensity resistance training, equivalent to at least 70% of an individual’s 1 repetition maximum. In recent years, systemic hypoxic stress has emerged as a stimulation condition that can induce more physiological and biochemical changes caused by resistance exercise. Hypoxic stress result in changes in neuromotor control, metabolic changes, hormonal changes, cellular swelling, and intracellular signaling pathways, similar to the effects of resistance exercise. The combination of hypoxic stress and resistance exercise is expected to have a greater effect on the improvement of muscular function and hypertrophy. Therefore, we examined the previous studies for understand the concept of intermittent hypoxic resistance training (IHRT) and its effectiveness, and to grasp the principle of IHRT to improve muscular function and hypertrophy. However, few investigations have examined the combination effects of hypoxic stress and resistance exercise, and as such it is difficult to make recommendations for implementing IHRT based on current understanding. It should also be acknowledged that a number of mechanisms proposed to facilitate the augmented response to IHRT remain poorly understood, particularly the systemic role of metabolic, hormonal, cellular swelling, and intracellular signaling pathways. Future research should examine the various physiological and biochemical mechanism and performance to resistance exercise in hypoxic condition and training in systemic hypoxic condition.

This study is about changes in antioxidant response during repeated apnea diving. The subjects are 16 male university students. The method is to measure MDA, SOD, red blood cell, lactic acid, blood suger, blood and heart rate at rest, after 5, 10, 15 and 20 times of repeated apnea diving in 5M diving pool. One-way ANOVA with repeated measure was performed to verify the difference in the mean between periods, and the LSD method was performed for post-hoc testing if there was any significance between groups. the statistical significance level was set as α=.05. As a result, there were significant differences in white blood cells, red blood cells, hemoglobin, hematocrit, blood glucose, lactic acid, and heart rate changes according to the number of times and time, but there were no changes in MDA and SOD. This showed that the intensity of apnea diving was low in male college students and there was no significant difference due to physical adaptation. Therefore, in future studies, in-depth studies of various variables appearing during apnea diving in various environments and conditions are required.

The purpose of this study is to verify the gait measurement function of the knee sleeve equipped with an IMU(Inertial Measurement Unit) sensor based on ICBM(IoT, Cloud, Big data, and Mobile) and to verify the effect of wearing and not wearing the knee sleeve to provide basic data on the development of the knee sleeve based on ICBM which can analyze gait pattern and improve gait ability. The measurement accuracy of the IMU sensor was verified by comparing the accelerations measured by the IMU sensor attached t o the knee s leeve and the 3D M otion C apture S ystem while g ait measuring in 2 0 elderly persons over 60 years old. Also 16 subjects, age of 20’s, and 15 subjects, age of 60’s, were analyzed for the effect of wearing and not wearing the knee sleeve for blood lactate, blood glucose, steps, gait tempo, and heart rate when walking. The results of this study are as follows. As a result of comparing the difference between the acceleration values measured by the IMU sensor attached to the knee sleeve and the acceleration values of the mass center of IMU sensor calculated by the motion analysis with RMSE(Root Mean Squared Error), the RMSE on the x-axis is 1.154, the RMSE on the y-axis is 5.765, and the RMSE on the z-axis is 2.145. Correlation analysis of the acceleration values of the mass center of IMU sensor(MCI) calculated by the motion analysis, the acceleration values measured by the IMU sensor(IMU), and the acceleration value of knee center(KNE) calculated by the motion analysis showed that MCI and IMU showed no significant correlation between the x-axis and the y-axis, indicating a significant correlation in the z-axis. IMU and KNE did not show a significant correlation on the x-axis and the z-axis, but a significant correlation on the y-axis.

This study was designed to examine the effect of short-term normobaric hypoxic training by reviewing the change of VO₂max, erythropoietin(EPO) and blood lactate level of Taekwondo players in high ground environment. Test subjects are 21 Taekwondo players: 16.5%O₂(2,000m altitude) environment training hypoxic group(HG) of 10, normal environment training control group(CG) of 11. Each group was analysed to examine VO₂max, EPO and blood lactate level before and after the 7days of training. As the result of research, there were changes in VO₂max and EPO before and after the training. However, they did not show the noticeable changes between the two groups. In case of blood lactate, HG shows more increase than CG, but, after 30 minutes and 3 minutes of training, HG shows decrease compared to CG. Through these results, hypoxic training intensity and period is assumed to be important to the training effect to elite players. In later research, the physical change needs to be studied by increasing intensity, period and frequency.
