본 연구는 초등학생 야구선수들의 훈련 및 경기과정에서 발생하는 운동 상해를 분석하여 선수들의 보호와 관리 를 체계적으로 수립하는 자료제공의 목적으로 수행되었으며, 그 결과는 다음과 같다. 운동 상해 중 상지에서는 팔꿈치 관절(37.7%)이 가장 높은 것으로 나타났으며, 하지에서는 발목관절(23.5%)이 가장 높은 것으로 나타났다. 몸통에서 는 허리부위(46.2%)가 가장 높은 것으로 나타났다. 또한 상해 원인 및 시기를 살펴보면, 우선 원인에서는 훈련 중 (76.2%)이 경기 중보다 높은 것으로 나타났으며, 시기에서는 겨울(42.9%)이 가장 높은 것으로 나타났다. 마지막으로 운동경력에 따른 상해 부위를 살펴보면, 운동경력이 높아질수록 모든 상해 부위가 함께 높아지는 것으로 나타났고, 그 중 상지가 다른 부위보다 가장 높은 것으로 나타났다. 따라서 본 연구에서는 초등학생 야구선수들의 상해실태를 조사해 본 결과 상지에서는 팔꿈치관절, 하지에서는 발목관절, 몸통에서는 허리부위에서 가장 높게 나타났으며, 상해원인은 훈 련 과정이 높은 것으로 나타났고, 상해 시기는 겨울철이 높게 나타났다. 운동경력에 따른 상해부위와의 관계는 운동경력 이 증가할수록 각 상해 부위도 그 빈도가 증가하며, 상지에서 더욱 증가하는 것으로 나타났다. The purpose of this study was to provide data to systemically establish the care and the management of athletes by analyzing the sports injuries that come about during the training and competition process of elementary school baseball players. The results are as follow, The elbow joint (37.7%) was the highest injury in the upper limb during the training, and the ankle joint (23.5%) was shown the highest injury in the lower limb. The lumbar (46.2%) was the highest in the trunk. also, when we look at the cause and timing of injury, firstly, 76.2% of the training was higher than during the game, and winter (42.9%) was the highest among the seasons. Lastly, when we look at the injuries according to the athletic career, as the athletic career increased, all injury sites increased together, and the upper limb was the highest than other limb. Therefore, in this study, it is analyzed that the prevention of injury of elementary baseball players should be managed priority in the prevention level of the elbow joint in the upper limb, the ankle joint in the lower limb, and the lumbar in the trunk, The cause of injury was intensive training process, and timing of injury was an high effect in winter. Relationships with injuries by athletic career increased the frequency of injuries as the more experience and especially increased in the upper limb.

벤치프레스 운동 시 탄성 바 길이에 따른 몸통 및 어깨 안정화 근육의 표면 근전도 비교 분석

박일봉,강슈호 한국체육무용과학회 2025 Journal of Sport and Dance Science Vol.5 No.1

본 연구는 벤치프레스 운동 시 탄성 바의 길이에 따른 몸통과 어깨 안정화 근육의 활성도를 표면 근전도(sEMG)를 이용하여 비교 분석하는 것을 목적으로 하였다. 이를 위해 20대 남성 14명을 연구대상으로 선정하였으며, 연구대상자는 각각 200 cm (3.5kg), 220 cm (4kg), 240 cm(4.5kg) 길이의 탄성 바를 사용하여 자신의 1RM의 60% 부하로 8회 반복하는 벤치프레스 운동을 수행하였다. 근육 활성도 측정을 위해 몸통 부위의 배곧은근과 배바깥빗근, 어깨 부위의 어깨세모근 앞쪽 섬유와 뒤쪽 섬유를 선정하였다. 자료처리를 위해 SPSS Win ver. 28.0 프로그램을 사용하여 유의수준 p<.05에서 일원배치 분산분석(ANOVA)을 실시하였다. 연구 결과, 240 cm 탄성 바를 사용한 경우 배곧은근, 배바깥빗근, 어깨세모근 전부(양측)에서 200 cm 및 220 cm 탄성 바보다 유의미하게 높은 근육 활성도를 보였다. 그러나 어깨세모근 뒤쪽섬유에서는 통계적으로 유의한 차이가 나타나지 않았다. 따라서 본 연구는 240 cm 길이의 탄성 바가 벤치프레스 운동 시 몸통과 어깨 부위의 안정화 근육 활성화에 더 효과적임을 제시하며, 이는 운동 및 재활 프로그램 설계 시 유용한 자료로 활용될 수 있을 것이다. Objectives This study aimed to compare and analyze the activation of stabilization muscles in the trunk and shoulder during the bench press exercise using surface Electromyography (sEMG) based on the length of elastic bars. Methods Fourteen male participants in their 20s (Age: 21.35±0.72 years, Height: 174.42±5.05 cm, Weight: 76.85±9.26 kg) were recruited as participants. Bench press exercises were performed using elastic bars with lengths of 200 cm, 220 cm, and 240 cm. Each participant performed the bench press with a load of 60% of their one-repetition maximum (1RM) for eight repetitions. sEMG was used to measure muscle activation. The selected muscles included the external oblique and rectus abdominis for the trunk, and the anterior and posterior fibers of the deltoid for the shoulder. Statistical analysis was conducted using one-way ANOVA with a significance level of .05. Results The comparison of muscle activation using sEMG across the three elastic bar lengths 200 cm(3.5kg), 220 cm(4kg), and 240 cm(4.5kg) revealed that the 240 cm bar resulted in significantly higher activation of the rectus abdominis, external oblique, and anterior fibers of the deltoid (bilaterally) compared to the 200 cm and 220 cm bars. However, no statistically significant differences were observed in the posterior fibers of the deltoid bilaterally. Conclusions The comparative analysis of three elastic bar lengths during the bench press exercise showed that the 240 cm bar elicited greater activation of the rectus abdominis, external oblique, and anterior fibers of the deltoid (bilaterally) than the 200 cm and 220 cm bars. These findings suggest that the 240 cm bar is more effective in activating stabilization muscles in the trunk and shoulder regions.

청소년 야구 투수의 투구 수 증가에 따른 근전도 비교 분석

박일봉 한국운동역학회 2025 한국운동역학회지 Vol.35 No.1

Objective: This study aimed to analyze changes in upper extremity muscle activation during repeated pitching by youth baseball players and to provide foundational data for injury prevention and training enhancement by assessing the impact of fatigue on electromyographic (EMG) signals. Method: The study involved 20 baseball pitchers (10 middle school and 10 high school players) from teams. Participants were selected based on their experience (minimum 5 years of pitching) and absence of injuries in the past six months. Surface electromyography (EMG) was used to measure the activity of eight key upper extremity muscles: trapezius, triceps brachii, biceps brachii, pectoralis major, deltoid, latissimus dorsi, flexor carpi radialis and extensor carpi radialis. Each participant performed fastball pitches on a mound with the pitching motion divided into six phases: wind-up, stride, arm cocking, arm acceleration, arm deceleration, and follow-through. Mixed-design analysis of variance (Mixed ANOVA) was used to evaluate changes in muscle activation, with statistical significance set at p<.05. Results: As the number of pitches increased, muscle activation across the upper extremity generally decreased, reflecting fatigue-related reductions in neuromuscular coordination. Significant reductions were observed in the trapezius and latissimus dorsi during the wind-up and stride phases and in the extensor carpi radialis, flexor carpi radialis and triceps brachii during the arm cocking and acceleration phases. While high school players demonstrated more stable muscle utilization due to efficient pitching mechanics, both groups experienced noticeable decreases in muscle activation in specific phases, indicating variability in fatigue accumulation based on age and skill level. Conclusion: Youth baseball pitchers exhibited overall reductions in muscle activation during repeated pitching, highlighting the impact of fatigue on inefficient muscle use and increased injury risk. Developing tailored training programs that address age and skill-specific fatigue management and promote balanced muscle development is essential. Such approaches are expected to improve pitching mechanics, prevent injuries, and enhance the performance of youth players.

Objective: This study was executed to compare and analyze shoulder muscle activation while using an inelastic bar and elastic bar during overhead press exercise. The stability and coordination of shoulder joints will be investigated by measuring and analyzing the EMG of the upper and lower arm muscles. Method: A total of 20 university male students were recruited by dividing into 2 groups; 10 elastic bar participants (age: 20.17 ± 0.41 yrs, height: 174.31 ± 3.34 cm, weight: 74.68 ± 5.65 kg) and 10 inelastic bar participants (age: 20.09 ± 0.23 yrs, height: 173.53 ± 4.11 cm, weight: 75.32 ± 3.31 kg) participated in this study. Results: The EMG analysis results of the four muscles measured in this study showed that there was no difference between the left and right muscles between the groups in Upper Trapezius muscle. In Deltoid, Infraspinatus, and Rectus Abdominis muscles, the elastic bar group was significantly higher than the inelastic bar group between groups, and there was no difference between left and right. Conclusion: Among the four muscles measured in this study, there was no difference between left and right in Deltoid, Infraspinatus, and Rectus Abdominis, but the elastic bar showed significantly higher muscle activity than the inelastic bar. Therefore, it was found that the elastic bar increases muscle activation during exercise than the inelastic bar, and in particular, it further increases muscle activation of the arms and torso, and exercise using the elastic bar can increase neuromuscular stabilization.
