Purpose: This study is to see if the calf muscle movement affects the length of stride, symmetry, and ability to overcome obstacles, and muscle activity in patients with hemiplegia. Methods: Electromagnetic signals were first measured by ankle plantar flexion or muscle testing in a supine position with 12 patient ankle plantar flexor in the standing position. In the second measurement, the length and symmetry of stride are measured through the gait analyzer. In the third measurement, the ability to measure obstacles was measured. The paired- T test revealed a significant difference. Results: After the intervention, the step length was significantly decreased (p<.05), while the speed and failure rate of the obstacle overcoming was significantly decreased (p<.05). also muscle actvitiy was significantly increased (p<.05), and muscle power was significantly increased (p<.05). the different was statistically significant between pre- and post-intervetion. but after intervention, the gait symmetry was no significantly difference (p>.05), between pre- and post-intervention. Conclusion: The results of this study show that the length of stride, ability to overcome obstacles, muscular activity, and muscle strength are increased more after exercise. Therefore, it is a movement that requires patients with hemiplegia to aim for calf muscle exercise because it increases the length of step in their daily lives, overcomes obstacles, and has a positive effect on muscle activity and muscle strength.

본 연구는 플로스 밴드(floss band, FB)를 이용한 혈류제한(blood flow restriction, BFR) 준비운동이 엘리트 육상선수의 스프린트 및 근 파워에 미치는 영향을 규명하는데 목적이 있다. 현역 단거리 육상선수 8명을 모집하여 통제 집단(control group, CG), 다리에 FB를 적용한 집단(flossing legs group, FLG), 그리고 다리와 팔에 FB를 적용한 집단(flossing legs and arms group, FLAG)으로 무작위 배정 후 7일의 Wash-out 기간을 두고 교차 적용하였다. 중재 방법은 FB를 다리 또는 다리와 팔에 감은 후 BFR 효과를 유도한 상태에서 20분간 각 개인이 평소 실시하는 일관된 준비운동을 실시하였다. 각 집단에 맞는 중재 적용 후 50m 스프린트 능력과 근 파워를 측정하여 집단 간 차이를 비교·분석 하였다. 연구 결과, 스프린트는 집단 간 차이가 나타났으며(p =.021), FLG가 CG에 비해 기록이 단축되었다(ES=0.59). 근 파워의 경우, 단일 다리 삼중 홉 검사의 좌측에서 집단 간 차이가 나타났으며(p=.037), FLG가 CG에 비해 더 좋은 기록 을 나타내었다(ES=0.97). 우측과 CMJ의 경우 집단 간 유의한 차이가 나타나지 않았다. 따라서 FB를 이용한 BFR 준비운 동 방법은 육상선수의 스프린트와 수평적인 파워 향상에 효과적인 방법으로 판단된다.

This study aims to investigate the effects of blood flow restriction(BFR) warm-up using floss band(FB) on sprint and muscle power in elite sprinter. Eight active sprinters were recruited and randomly assigned to a control group(CG), a group with floss band applied to the legs(flossing legs group, FLG), and a group with floss band applied to legs and arms(flossing legs and arms group, FLAG), with a 7-day wash-out period between crossover applications. The intervention involved performing typical warm-up exercises for 20 minutes under induced BFR conditions after applying FB to the legs or both the arms and legs. Sprint and muscle power were measured after the intervention for each group, and group differences were compared and analyzed. The results showed significant differences in sprint between the groups(p=.021) and FLG improved compared to CG(ES=0.59). In terms of muscle power, significant differences were observed in the left leg at the single-leg triple hop test(p=.037), and the FLG showed better performance compared to the CG(ES=0.97). No significant differences were found between the groups for the right leg and countermovement jump(CMJ). In conclusion, BFR warm-up using FB is considered an effective method for improving sprint and horizontal power in sprinters.

The purpose of this study was to determine the effects of beta-alanine supplementation and altitude training on aerobic capacity(200m swim performance) and muscle power in K university’s swimmers. Fourteen male swimmers(two groups; β-ala & Con) were performed swim trials in sea level and altitude(1980m) for respectively 4wk(total 8wk). We were checked 200m X 5th records and muscle power(60o/sec Peak torque) analysis at 3 times(pre, 4wk & 8wk). Body compositions(weight, %BMI, muscle mass) were measured pre & post(8wk). The results showed that 200m swim performance records was significantly different pre training between sea level training (p<.05) and pre training between altitude training (p<.001) in β-ala group. But not Con group(placebo). Muscle power(60o/sec Flexion Peak torque) records was significantly different pre training between sea level training (p<.05) and pre training between altitude training (p<.05) in β-ala group. But not Con group(placebo). In conclusion, efficiency of beta-alanine supplementation were increased a beneficial effect on 200m swim performance(aerobic capacity) and isokinetic’s muscle power in elite swimmers.

This study investigated the prevalence of depression and levels of physical fitness in high school students during the coronavirus disease 2019 (COVID-19) pandemic. One hundred fifty participants were divided into four groups according to the number of days that they felt de-pressed due to the COVID-19 during the last 7 days: no-depression group (NDG, n=17), some-depression group (SDG, n=32), occasion-al-depression group (ODG, n=81), and most-depression group (MDG, n=20). Shuttle run for endurance capacity and standing long jump for muscle power were selected to estimate the states of type I and type II muscle fibers, respectively. This study found that the Center for Epide-miologic Studies Depression Scale score of MDG was significantly higher than those of other three groups. In addition, ODG and MDG showed the lowest interest in their school studies compared with other groups. Endurance capacity showed a significant difference among groups, whereas muscle power showed no significant difference among groups. In conclusion, this study suggests that higher levels of depres-sion reflect a greater lack of interest in life and academics. Furthermore, lower endurance capacity appears to be associated with more severe levels of depression. This highlights the importance of maintaining type I muscle fibers through regular aerobic exercise.

The purpose of this study was to investigate the correlation between muscle power of the wrist flexor muscles and muscle strength according to grip type, such as the strength difference between a two-finger pinch grip and four-finger pinch grip. After the preliminary study, six subjects who agreed to participate in this study were recruited and the experiment was conducted. The power of the wrist flexor was measured using a digital manual muscle tester in the sitting position, and the grip strength according to the grip type was measured with a digital grip dynamometer. Spearman's nonparametric test was used to determine the correlation between wrist flexor power and grip strength of the power grip. An independent t-test was used to determine the significance level of the grip strength in the two-finger grip and four-finger grip. The significance level was set at p<.05 for all statistical tests. There was no interaction between the wrist flexor power and grip strength according to grip type (two-finger pinch grip, four-finger pinch grip, and power grip), but there was a significant difference in grip strength between the two-finger grip and four-finger grip (p<.05). The grip method that is necessary for grip strength when performing work may help to prevent musculoskeletal disorders.

The purpose of this study was to investigate differences of maximum muscle strength and isokinetic knee and core muscle functions accord-ing to pedaling power of racing cyclist candidate. Subjects for this study were 200 racing cyclist candidates and divided into four groups: top 10% peak power group (TPP, n=20), low 10% peak power group (LPP, n=20), top 10% average power group (TAP, n=20), and low 10% average power group (LAP, n=20). The maximum muscle strength was consisted of grip strength, bench press and squat measured by Ariel device, and isokinetic knee and core muscle functions were analyzed by Humac Norm device. Significant differences between groups were determined with one-way repeated analysis of variance. As the result of this study, TPP and TAP groups showed significantly decreased body-fat mass and increased free fat mass when compared to LPP and LAP groups. The maximum strength of grip and squat was significantly higher in TPP and TAP than in other groups. Isokinetic knee extension and flexion strength was higher in TPP and TAP groups as well as isoki-netic trunk extension and flexion functions were highest in TPP group. Thus, our findings suggest new evidence that muscle mass, maximal muscle strength, and isokinetic muscle functions might be important predictors of racing cyclist performance.

Purpose: This study compared the changes in power and agility and muscle tone of the quadriceps and hamstring muscles after 10 weeks of plyometrics or weight training to strengthen the leg muscles. The following conclusions were obtained. Methods: Subjects were randomly assigned to a plyometrics group (n = 10) and a weight training group (n = 10) from male college students who did not recently participate in a regular exercise program. Plyometrics and weight training were performed three times a week for 10 weeks with 60 minutes a day. The exercise intensity was divided into 3 stages, and the weight training group and the plyometrics group performed 3 sets of 1 repetition maximum (RM) of 60, 70, 80%, and 10, 12, 15 repetitions (rep), respectively. Results: First, there was an interaction effect between the group and time period on power. The plyometrics group showed a greater increase in power than the weight training group. Second, there was an interaction effect between the group and time period on agility. While agility improved in the plyometrics group, no significant difference was observed in the weight training group. Third, there was an interaction effect between the group and time period on the muscle tones of the left and right quadriceps muscles. The muscle tone increased more in the weight training group than in the plyometrics group. Fourth, there was an interaction effect between the group and time period on the muscle tones of the left and right hamstring muscles. The muscle tone increased more in the weight training group than in the plyometrics group. Conclusion: The change in muscle tone value was found to have a significant relationship with the increase in muscle strength and power through plyometrics and weight training, and additional research should be conducted to investigate the relationship between exercise performance ability and muscle tone.

The purpose of this study was to evaluate the effects of a 6-week resistance band training program on balance, reaction time, and muscle strength in female futsal players to develop evidence-based programs for performance improvement and injury prevention. Twenty-four female amateur futsal players were randomly assigned to a control group (Control Group;CG, n=12) or a resistance band group (Band Group; BG, n=12), with both groups completing twice-weekly training sessions. The BG progressed from low-intensity to high-intensity resistance bands over the 6 weeks, with sessions lasting 15-20 minutes. Dynamic balance was measured using the Y Balance Test (YBT), reaction time with BlazePod, and muscle strength with the counter-movement jump (CMJ). The results showed significant improvements in balance (p < .01), reaction time (p < .001), and muscle strength (p < .01) in the BG. However, the one-legged triple jump test did not show significant changes (p = .183). These findings suggest that resistance band training is effective in enhancing balance and reaction time in female amateur futsal players. Although limited to amateur athletes, this study provides a valuable basis for the development of training programs and injury prevention strategies tailored to female futsal players.

The purpose of this study was to determine comparison of aquatic- and land-based plyometric training on muscle strength, power, balance, co-activation, and muscle soreness. 30 college age men were randomly assigned to 1 of 3 groups(Aquatic plyometric training(AQ), Land plyometric training(LD), and control group(CON)). Plyometric training was consisted of about 10 min. of warm-up and cool-down, and 40 min. of 3 sets of plyometric exercises. AQ was performed in depth of about 120cm(about 47in.) of swimming pool. Muscle strength, muscle power, co-activation and balance were measured in pre- and post-training. Muscle soreness was measured at pre-training, after 1st training, mid-training(3th week) and post-training. Two-way ANOVA with repeated measures and LSD were used to analyze data. Significant level was α=.05. Muscle strength and co-activation of knee flexor(p<.05) and muscle strength of ankle plantar flexor(p<.001) were increased for AQ and LD. AQ(p<.001) and LD(p<.01) outperformed CON in vertical jump. Dynamic balance was significantly greater in AQ compared to CON at post-training(p<.05). Muscle soreness of rectus femoris was significantly greater in LD compared to CON in after 1st training(p<.001) and mid-training(p<.01). This study has proposed that Aquatic-based plyometric training can result in increasing muscle power and function and is effective on decreasing muscle soreness and enhancing balance in short-term training.

There are various approach of taping. Diversity in the taping approach makes it difficult to establish the grounded theory of taping. Therefore, it is necessary to classify the taping approach and establish each grounded theory. Orthopedic medicine taping, one of the taping approaches, include an approach called power source muscle taping. This text is intended for neurophysiological analysis of power source muscle taping. The power source muscle taping is very similar to kinesio taping. But it is not exactly the same. Power source muscle taping is only intended for pain only during movement. Therefore, power source muscle taping is only for muscles. Also, in the case of motion sickness, the organic damage of muscles also applies sports taping and excludes power source muscle taping. It is only intended for those with functional impairments of muscles. If the organic damage is repaired, it is subject to power source muscle taping. Methods of orthopedic taping include elasticity taping and cause taping. Elastic taping is attached on a muscle using elastic tape from origin to insertion. cause taping apply an inelastic tape to any part of the muscle. Use the form of cross tape and response point tape for cause taping. Taping attached to muscles can be distinguished by effects caused by physical effects and effects of stimulation. Kinesio tapping has presented the promotion of lymphatic flow by physical effects as the grounded theory. Even in orthopedic tape, the reduction in sensitivity of the muscle spindle due to physical effects was presented by Arikawa Isao. However, I argue that power source muscle taping is a facilitating effect of muscle tension caused by the stimulation effects of taping. Muscles with functional disabilities have some of the muscle fibers tensed in some areas, while others have been relatively less tense. In the end, the overall tension in the muscles is reduced. In this state, the movement causes pain by concentrating stress on the tense muscle fiber. Stimulation by power source muscle taping is carried to the thalamus through the posterior column, but before that, it is delivered to the anterior horn to excite the α-motor fiber and produce a reaction of autogenetic excitation that tensions the stimulated surrounding muscles. In conclusion, it is thought that increasing the overall tension of muscles with functional disabilities reduces pain.

본 연구는 청소년 태권도 선수 대상으로 4주간 발목 파워트레이닝을 실시하여 등속성 발목근력, 고유수용성감각 과 균형성에 미치는 영향을 확인하기 위하여 실시되었다. 연구대상은 20명 남자 선수들로 선정하였으며 집단의 분류는 발목파워트레이닝 그룹(n = 10)과 통제 그룹(n = 10)으로 구성하였다. 발목 파워트레이닝 적용은 주5일, 워밍업과 쿨다 운 시간을 포함하여 100분 실시하였다. 본 연구를 통해 얻은 결과는 다음과 같다. 첫째, 파워트레이닝 프로그램 후 각속도 60°/sec와 180°/sec에서 등속성 하지근력이 통제그룹보다 증가된 결과를 나타냈다. 둘째, 발목 파워트레닝 그룹이 고유수용성감각에서 발목 파워트레닝 프로그램 후 향상된 결과를 나타냈다. 셋째, 청소년 태권도선수들에서 발목 파워트 레이닝 프로그램 후 균형성에서 발목 파워트레이닝 그룹이 유의한 증가를 나타냈다. 결론적으로 발목 파워트레이닝은 청소년 태권도 선수들에서 등속성 발목근력, 고유수용성 감각과 균형성 능력 향상에 영향을 미치는 것으로 확인되었다.

Although many studies have focused on strength or power for adults, no comprehensive researches have investigated the use of the ankle power training and analysis of ankle strength, proprioception and balance in young athletes. The study subjects were 20 male high school students in elite taekwondo atheltes. They were divided into the ankle power training group(PTG, n = 10) and a control group(CON, n = 10). Taekwondo athletes were treated with pover training five times per week for 4weeks. All the data was analyzed using ANOVA by repeated measures analysis of variance. Significant differences were observed between the two groups in PTG group an CON group isokinetic ankle muscle strength 60°/sec(left: DorsiFlexion; p < 0.001 and PlantarFlexion: p < 0.001; right: DorsiFlexion; p < 0.001 and PlantarFlexion; p < 0.001), isokinetic ankle muscle strength 180°/sec(left: DorsiFlexion; p < 0.001 and PlantarFlexion; p < 0.001; right: DorsiFlexion; p < 0.001 and PlantarFlexion; p < 0.001), proprioception(p < 0.01) and balance(p < 0.001) These results suggest that ankle power training improves strength fitness, lower body balance and proprioception of joint in young taekwondo athetes.
