이 연구의 목적은 근거 기반 실천의 중요성을 인식하고 체계적 문헌 고찰을 통해서 태권도 수련이 초등학생의 체력에 어떠한 영향이 있는가를 확인하고, 구체적인 수련 형태(강도, 기간, 빈도, 시간)를 조사하는 데 있다. 논문 데이터베이스는 KISS, RISS, 그리고 DBpia가 사용되었으며, 초등, 태권도, 체력 등의 주제어를 사용하여 논문을 검색하였다. 검색된 논문 226편 중 연구 선별 기준에 적합한 10편이 최종적으로 선정되었고, 분석 결과 다음과 같은 결론을 얻었다. 첫째, 초등학생에게 적용된 태권도 수련 중재 프로그램은 초등학생의 순발력, 민첩성, 근지구력, 유연성, 신체조성, 그리고 평형성의 향상에 효과가 있었다. 둘째, 초등학생의 체력 수준을 향상시킬 수 있는 효과적인 태권도수련 프로그램은 60분으로 구성(준비운동-본운동-정리운동)하는 것이 바람직하며, 기본동작, 품새, 겨루기, 격파를 포함하는 것이 효과적이다. 셋째, 초등학생의 체력 수준에 영향을 미치는 수련 프로그램의 적정 강도는 결과가 일치하지 않았다. 넷째, 초등학생의 체력 수준에 영향을 미치는 수련 프로그램의 적절한 기간은 12주, 수련 빈도는 주 5회가 가장 바람직할 것으로 보인다. The purpose of this study was 1) to conduct a systematic literature review of studies examining the effects of physical fitness on taekwondo training in elementary students and 2) to present specific principle about taekwondo training (i.e., intensity, frequency, period, & volume) based on the findings. Databases (i.e., KISS, RISS, & DBPIA) were used for literature search with predefined keywords (e.g., elementary, taekwondo, & physical fitness). A total of 226 potential studies were identified and 10 studies were finally selected for the data abstraction. Based on the results, a taekwondo training was determined to be evidence based. First, the taekwondo training in elementary students had positive effects on quickness, agility, muscle endurance, flexibility, body composition, and balance. Second, It was recommended that the effective taekwondo training to improve the level physical fitness should be composed of warm up(10min), main exercise(40min), and warm down(10min). and Including basic movement, poomsae, kyorugi, break, and basis fitness training in the program is effective for elementary students. Third, an appropriate intensity of the program that affects physical fitness was drawn an inconsistent result. Lastly, a proper duration, frequency, and volume sere 12 weeks, 5 day/week, and 60 min/day, respectively.

The purpose of this study was to analyze motivation factors of university students participating in physical education swimming class by using inductive content analysis approach. The subjects of the study were 228 students who participated in swimming classes from the second semester of 2016 to the first semester of 2018. The participants answered an open-ended question asking them for their motives of swimming class participation, and triangulation was applied to ensure validity and reliability of data analysis. The result of analysis showed that factors of participation motivation in swimming classes are categorized as educational motivation(24.5%), physical healthy motivation(14.8%), psychological motivation(40.3%), social motivation(9.0%), and environmental motivation(11.4%). These results suggest that the continuing interest and research on the improvement and development of physical education facilities, institutional system, swimming education contents in university physical activity classes should be continued.

원심성운동의 지속시간이 혈압, 심박수, 혈중 젖산, 당에 미치는 영향

석창혁(Seok, Chang-Hyeok),권영우(Kwon, Yeung-Woo) 한국체육과학회 2017 한국체육과학회지 Vol.26 No.3

The purpose of this study was to assess the duration of eccentric(2-second vs. 4-second) muscle contractions and their effect on circulatory factors(blood pressure, heart rate) and metabolic substrate (lactate, glucose) using acute resistance exercise. Ten college-aged males were randomized and assigned to one of the two eccentric acute exercise groups that incorporated different patters of contraction. The control group utilized two-second-eccentric contractions while the 4second group performed four-second eccentric contraction. For every repetition, all two groups utilized two-second concentric contractions. All participants completed acute resistance exercise at intensity of 80-85% of 1RM. Blood pressure measured before, immediately after exercise, 5. 10, 15, 20min post exercise. Heart rate measured before, immediately after exercise, 1min post exercise. Lactate, and blood glucose concentration measures before, immediately after exercise, 30min post exercise. Significant group×time interaction effects were found for blood glucose concentration. Blood glucose data indicated that the 2s and 4s group experienced a significant reduction in immediately after exercise and 30minutes post periods and thus exercise induced decrease was more higher during 4second eccentric exercise than during 2second one. While heart rate did not reach significance but there was a trend towards a difference with 4s eccentric exercise. No other significant group×time interaction effects were found for the variables.

석창혁(Chang Hyeok Seok),정혁(Hyuk Chung) 한국체육측정평가학회 2012 한국체육측정평가학회지 Vol.14 No.2

이 연구에서는 윤영철(2008)이 한국어로 번역하여 제시한 신체적 자기효능감 척도(PSES-K)의 심리측정학적 특성을 검사하였다. 전체문항을 한 경우와 PPA요인에 대한 내적일관성 신뢰계수는 양호한 반면 PSPC요인의 신뢰계수는 낮게 나타났다. 탐색적 요인분석에서도 PSPC요인에 포함된 문항들 다수가 낮은 요인 적재값을 갖거나 어느 요인에도 포함되지 않는 결과를 보였다. 확인적 요인분석 결과에 따르면 대부분의 적합도 지수에서 부적합한 것으로 나타났다. 추가적으로 대조되는 두 집단을 이용한 평균비교, 신체적 자기개념 점수와의 상관분석, 체지방률과의 상관분석 결과를 제시하였다. 요약하면, PSES-K는 세밀한 번역과정을 거쳐 제시된 것으로 알려졌으나 이를 이용한 신체적 자기효능감 측정은 부적합한 것으로 결론지을 수 있다. 이러한 결과는 번역에 사용된 원본 검사지가 외국에서 1980년대 초반에 개발되었다는 점에서 기인된 것으로 보인다. 그러므로 국내에서 적합하게 사용할 수 있는 새로운 신체적 자기효능감 검사지의 개발이 요구된다. The purpose of this study was to investigate the psychometric properties of Korean Physical Self-Efficacy Scale (PSES-K). Evidences for the validity and reliability of the scale were presented in a series of analyses. While internal consistency reliabilities for PPA subscale and the scale were acceptable the coefficient alpha for PSPC subscale was problematic. According to the results from exploratory factor analysis there were four items showing relatively low factor loadings. Most indices resulted from confirmatory factor analysis showed poor fit then the two factor model might be regarded as inappropriate for measuring physical self-efficacy in undergraduate students. For external validity, three analyses such as t-test for two heterogeneous groups, a correlation analysis between the measures from the PSES-K and the Physical Self-Concept Scale, and correlations between the measure of the PSES-K and the percent of body fat were conducted. In summary developing a new scale was recommended rather than revising the PSES-K, which was translated from the scale developed in 1982.

The purpose of this study were to develop a subjective crawl-swim skill test and to determine the applicability of the skill test to physical activity courses in colleges. To develop the skill test inventory literature review and constructing correct crawl-swim technique were conducted followed by the expert review for content validity. Final version of the inventory consists of four major parts (stroke, kick, breathing, and overall) with 18 items. A three-point scale was employed for the inventory; Inferior-Moderate-Superior. Data from 77 subjects (48 college students and 29 middle & high school swimming athletes) was used for group difference tests and correlation analysis between 50-meter crawl swimming records and test scores. The subjective crawl-swim skill test discriminated the groups based on their swimming skill levels and the test scores were highly correlated with respective swimming records. In summary the inventory is applicable to evaluate and grade college students in physical activity courses even though it might be insufficient to test expert level swimmers and athletes.

The purpose of this study is to analyze deeply the level of knowledge among athletes who practice the traditional Korean sports ssireum and taekwondo, regarding the history of their sport. This study is part of the importance of Korean history, which is emerging recently, and it was conducted as a way to protect the history of our nation. In order to achieve the purpose of the study, 10 subjects (5 university ssireum athletes and 5 college taekwondo athletes) participated in the study. The data was collected through in-depth interviews from February to March 2017 and the following results were obtained from the textual analysis. Firstly, both ssireum and taekwondo athletes recognized the importance of Korean history, but they did not recognize the importance of the history for their sport. Secondly, the perception of the history of their sport was also very low as they were not aware of the importance of the history of their sport. Thirdly, most athletes responded that they had a lot of limitations when they tried to l earn the history. These results can be said to raise awareness a b out the historical recognition level of athletes practicing traditional Korean sports.
