이병근,이동규 대한운동사협회 2009 아시아 운동학 학술지 Vol.11 No.3

[INTRODUCTION] The purpose of this study was to develop 1-RM prediction equation of leg extension and leg curl from 7-10RM and anthropometric variables, and to verify the equation by the verify group. [METHOD] Trained adult males of development group and verification group measured 1-RM, 7-10RM and anthropometric variables(development 46, verification 17). As a results of regression analysis, the 7-10RM equation of LE was “4.275 + 1.255⨯ 7-10RM(kg)”(p<.01) and the equation of anthropometric variables was “y = -4.411 ⨯ weight(kg)”(p<.05). The 7-10RM equation of LC was “y = 29.946 + 0.821 ⨯ 7-10RM(kg)”(p<.01), the equation of anthropometric variables was “y = - 48.838 + 2.428 ⨯ thigh girth(cm)”(p<.01). [RESULT] There were no significant differences and high correlations(0.98~0.99, p<.01) between measured 1-RM and estimated 1-RM from 7-10RM, both in LE and LC. However, in the case of estimation from anthropometric variables, there was no significant difference only in LC, and low correlation(0.11~0.39, p>.05) was shown between measured 1-RM and estimated 1-RM. The 7-10RM equation had a good validity, but the equation of anthropometric variables had a limitation. [CONCLUSION] The satisfied 1-RM equation in both LE and LC were made from 7-10RM, but not from anthropometric variables for trained adult males. [서론] 본 연구의 목적은 웨이트 트레이닝 유경험자를 대상으로 최대하근력인 7-10RM과 신체자료를 이용한 leg extension(LE)과 leg curl(LC) 동작의 1-RM 추정식을 개발하고, 추정식의 타당도를 검증하는 데 있다. [방법] 본 연구의 대상은 웨이트 트레이닝을 2개월 이상 참여한 성인 남자이다(추정식 개발 46명, 검증 17명). 1-RM, 7-10RM 및 신체자료를 측정하고 회귀분석을 실시하였다. LE 1-RM의 7-10RM 추정식은 “y = 4.275 + 1.255 × 7-10RM(kg)”이고(p<.01), 신체자료 추정식은 “y = -4.411 × 체중(kg)”이었다(p<.05). LC의 7-10RM 추정식은 “y = 29.946 + 0.821 × 7-10RM(kg)”이고(p<.01), 신체자료 추정식은 “y = - 48.838 + 2.428 × 대퇴둘레(cm)”이었다(p<.01). 검증집단을 대상으로 하여 측정 1-RM과 추정 1-RM을 비교하였다. [방법] LE과 LC 모두 7-10RM 추정식의 경우, 측정 1-RM과 추정 1-RM은 유의한 차이가 나타나지 않았으며, 0.98~0.99의 높은 상관이 나타났다(p<.01). 그러나 신체자료 추정식의 경우, LC에서만 유의한 차이가 나타나지 않았고, 상관계수도 0.11~0.39로 7-10RM 추정식보다 매우 낮으며, 유의한 상관이 나타나지 않았다. 7-10RM 추정식은 타당도 측면에서 의미가 있으나 신체자료 추정식은 제한점이 나타났다. [결론] 웨이트 트레이닝 유경험자를 대상으로 7-10RM으로 LE과 LC 동작에서는 양호한 1-RM 추정식을 산출할 수 있으나, 신체자료 추정식은 양호한 추정식이 산출되지 않았다.

이 연구는 weight training시 보다 효율적인 1RM 재설정 시기를 제시하는데 목적이 있다. 남자고등학교 2학년 학생을 1RM 재설정 시기를 기준으로 A(1주), B(2주), C(3주), D(4주) 그룹, 각 10명씩 총 40명을 유의 추출하여 12주간, 주 3회 55~70분간 70~80%RM의 weight training을 실시하여 각 그룹내·간의 시기별 변화율을 비교한 결과, bench press, squat, dead lift는 모두 그룹 내 운동 전·후 향상되었으며, 그룹 간 비교에서는 2주, 3주, 4주마다 1RM 재설정 그룹이 1주마다 1RM 재설정 그룹보다 향상되었다. testosterone은 그룹 내·간, 운동 전·후 차이가 없었다. CPK는 그룹 내 운동 전·6주 후 2주, 4주마다 1RM 재설정 그룹에서 감소하였으며, 그룹 간에는 차이가 없었다. 따라서 남자고교생의 WT 프로그램에서 1RM 재설정 시기가 testosterone, CPK에는 영향을 미치지 않았으며, 최대근력 향상 면에서는 2~4주의 1RM 재설정 시기가 효과적인 것으로 본다. The purpose of this study was to investigate more effective 1RM resetting time in WT program after comparative analysis of 1RM, testosterone, and CPK variations in male high school students. Forty subjects participated in this study from P high school in B metropolitan city. The subjects were grouped according to A(1week), B(2weeks), C(3weeks), and D(4weeks) on 1RM resetting time respectively in weight training period. The application of WT program for 12weeks was performed according to 55~70minutes per day, 3times a week, 70~80%RM, 8~12 repetitions, and 3sets. The detailed results of this study were as follows; 1) 1RM of bench press, squat, and dead lift between pre-exercise and post-exercise were all significantly improved in intragroup. 1RM resetting group of 2weeks, 3weeks, and 4weeks each in intergroup comparison were significantly improved better than 1RM resetting group of each week. 2) There was no significant difference in testosterone between intragroup, and intergroup, pre-exercise, and post-exercise. 3) The group was controlled 1RM resetting in pre-exercise and 2weeks, 4weeks each after 6weeks was significantly decreased in CPK, and there was no significant difference among each group. In conclusion, these results indicated that 1RM resetting time in WT doesn't lead to testosterone and CPK variations in male high school students, but 1RM resetting time from 2 to 4 weeks is effective on improvement of maximal strength.

This study aimed to calculate the 1RM(one repetition maximum) estimated regression equation from the weight of each 6-13RM that is lower than the 1RM, to set the appropriate exercise intensity for improving athletic ability for the purpose of competitions. The subjects were 202 female students from the Seoul Women’s University and the exercise used for measurement was the bench press. The experimental procedure was as follows: first, the subject’s body composition analysis was measured. Second, the 1RM was measured, followed by rest for more than an hour. Third, 2.5 - 10 ㎏ was gradually reduced from the 1RM weight and the subject’s ability to lift the weight was checked. Using the age, BMI, and submaximal muscular measurements, a simple regression equation and regression equation was calculated and the results are as follows. The study result of simple regression analysis is [0.222+(1.239×6RM)(R²=92.7%)], [5.060+(0.974×7RM)(R²=73.8%)], [4.002+(1.060×8RM)(R²=84.9%)], [4.467+(1.095×9RM)(R²=84.0%)], [4.902+(1.033.×10RM)(R²=77.9%)], [3.839+(1.167×11RM)(R²=86.8%)], [6.209+(1.075×12RM)(R²=85.7%)], [3.271+(1.266×13RM)(R²=86.6%)]; the results of a multiple regression analysis adding the age and BMI are [-8.168+(0.202×age)+(0.262×BMI)+(1.164×6RM)(R²=94.0%)], [-3.993+(0.170×age)+(0.343×BMI)+(0.889×7RM)(R²=76.4%)], [2.825-(0.105×age)+(0.216×BMI)+(0.998×8RM)(R²=86.1%)], [-7.054+(0.064×age)+(0.596×BMI)+(0.958×9RM)(R²=88.1%)], [2.722-(0.165×age)+(0.293×BMI)+(1.010×10RM)(R²=79.8%)], [-3.545+(0.149×age)+(0.246×BMI)+(1.102×11RM)(R²=88.3%)], [0.709+(0.084×age)+(0.223×BMI)+(1.0l6×12RM)(R²=86.8%)], [-3.785+(0.006×age)+(0.473×BMI)+(1.084×13RM)(R²=88.0%)]. The regression equation calculated from this study can predict the maximum strength of female college students using bench press with a high degree of accuracy because of its high explanatory power(R²) and the use of multiple regressions, which can increase the explanatory capacity from 1.3 to 4.1%.

본 연구는 체급간 대학 유도선수들의 유ㆍ무산소 체력(SJFT, 1RM, 최대산소섭취량)의 차이를 비교, 분석하고 각 요인들간의 관련성을 밝히는데 목적이 있다. 피험자는 Y대학교 유도학과에 재학 중인 남자 유도 선수 중 5년 이상 운동경력이 있는 자들로 전국대회 3회 이상 입상경력이 있는 선수 19명을 대상으로 60kg~66kg급을 경량급(6명), 73kg~90kg급을 중량급(8명), 100kg 이상을 헤비급(5명)으로 크게 3그룹으로 분류하여 측정하였다. 자료분석은 SPSS 17.0 program을 활용하여 기술통계, 일원변량분석, 상관분석을 사용하였으며, 결과는 다음과 같다. 첫째, 체급별 유·무산소 체력차이에서 최대산소섭취량과 SJFT의 메치기 합은 경량급, 중량급, 헤비급 순으로 집단 간에 통계적으로 유의한 차이가 나타났으며, 로우 1RM과 스쿼트 1RM은 헤비급, 중량급, 경량급 순으로 체급간에 통계적으로 유의한 차이가 나타났다. 둘째, 신체둘레와 1RM의 관계는 벤치프레스는 가슴과 다리둘레를 제외한 요인에서 정적으로 유의한 상관이 나타났으며, 로우 1RM과 스쿼트 1RM은 가슴둘레를 제외한 요인에서 정적으로 유의한 상관을 나타냈다. 데드리프트는 엉덩이 둘레를 제외한 요인에서 정적으로 유의한 상관이 나타났다. 셋째, 비만도에 따른 유·무산소 체력의 관계에서 BMI는 최대산소섭취량과 부적으로 유의한 상관을 나타냈으며, SJFT, 벤치프레스 1RM, 로우 1RM, 스쿼트 1RM, 데드레프트 1RM에서 정적으로 유의한 상관을 나타냈다. 최대산소섭취량은 SJFT와 유의한 상관관계가 나타나지 않았으며, 로우1RM과 부적으로 유의한 상관을 나타냈다. SJFT는 스쿼트 1RM에서 정적상관을 나타냈다. 결론적으로 유도 경기의 특성에 따라 체급간에 유·무산소 체력요인은 차이가 있는 것으로 나타났으며, 신체둘레와 1RM, 비만도에 따른 유·무산소 체력은 서로 상관이 있다는 것을 밝혀냈다. 이를 바탕으로 각 체급의 선수들의 특성을 고려하여 유도훈련 시 체계적이고 과학적인 프로그램을 계획하고 실천한다면 선수들의 경기력 향상에 큰 영향을 미칠 것으로 판단된다. The purpose of this study is to compare and analyze difference in aerobic·anaerobic fitness of university Judo players between weight divisions, and to clarify relevancy among factors in each. Subjects were those who have exercise career in over 5 years among male Judo players of attending the Dept. of Judo at H university. It measured by classifying subjects largely into 3 groups by having 60kg~66kg class as lightweight(6), 73kg~90kg class as middleweight(8), 100kg~over 100kg class as heavyweight(5) targeting 19 players who have the awarding career in over 3 times at National Competition. Data analysis was used descriptive statistics, One Way ANOVA, and Pearson`s Correlation by utilizing SPSS 17.0 program. The results are as follows. First, in difference of aerobic·anaerobic fitness by weight division, the total of the maximal oxygen uptake and SJFT(special judo fitness test) throw was in order of lightweight, middleweight, and heavyweight. Row 1RM and squat 1RM were indicated the statistically significant difference by weight division in order of heavyweight, middleweight, and lightweight. Second, in relationship between body circumference and 1RM, the Bench Press was indicated the positively significant correlation in factors except chest and leg circumference. Row 1RM and squat 1RM showed the positively significant correlation in factors except chest circumference. Dead-Lift showed the positively significant correlation in factors except hip circumference. Third, in relationship of aerobic·anaerobic fitness according to obesity index, BMI showed negatively significant correlation with maximal oxygen uptake. The positively significant correlation was indicated in SJFT, bench press 1RM, row 1RM, squat 1RM, and dead-lift 1RM. Maximal oxygen uptake wasn`t shown significant correlation with SJFT, and showed negatively significant correlation with row 1RM. SJFT showed positive correlation with squat 1RM. In conclusion, the factors of aerobic·anaerobic fitness by weight division were indicated to have difference according to characteristic of Judo game. The aerobic·anaerobic fitness according to body circumference, 1RM, and obesity index was clarified to have mutual correlation. Given planning and practicing a systematic and scientific program of Judo training by considering characteristics of players in each weight division based on this, it is judged to be likely to have great influence upon enhancement in players` athletic performance.

정경렬(KyungRyulChung),김사엽(SaYupKim),박기덕(GiDuckPark),주성범(SungBumJu) 한국체육학회 2010 한국체육학회지 Vol.49 No.1

본 연구는 고령여성의 근저항트레이닝 적용시 1RM(10~20%, 30~40%)과 RPE(10-12)를 통한 운동강도 설정에 따른 근력향상 효과를 검증하고자 하였으며, 이에 36명의 고령여성을 10-20%RM, 30-40%RM, RPE 10-12 그룹으로 나누어 12주간의 근저항트레이닝 적용 전, 6주, 12주에 따라 9개 항목(arm curl, shoulder press, chest press, lat pull down, leg extension, leg curl, leg press, hip abductor, abdominal)의 1RM을 측정하였다. 1RM의 변화에서는 모든 그룹에서 운동시기(운동전, 6주, 12주)가 지남에 따라 공통적으로 1RM이 향상되는 경향을 나타냈으며, 특히, 12주에서는 그룹간의 비교에서 10~20%RM그룹에 비해 RPE 10-12그룹이 더 높은 1RM 향상효과를 나타냈다. 이상의 결과를 종합하여 볼 때, 고령여성의 근저항트레이닝시 1RM(10~20%, 20~30%)과 RPE(10-12)를 통한 강도설정에 따라 공통적으로 근력향상이 효과가 나타나 그룹간의 의미있는 차이를 확인할 수 없었으나, 12주에서 10~20%RM그룹에 비해 RPE 10-12그룹이 더 높은 1RM 수치를 나타낸 점에 주목하여야 할 것이다. The purpose of this study was to evaluate effects of improvement of muscle strength on exercise intensity of 1RM and RPE during muscular resistance training in the elderly women. Subjects were divided 3 group(10~20%RM group, 30~40%RM group, RPE 10-12 group) from 36 elderly women. The subjects performed muscular resistance training for 12 weeks and effects on 1RM(arm curl, shoulder press, chest press, lat pull down, leg extension, leg curl, leg press, hip abductor, abdominal) have been evaluated. Analysis of the 1RM, All group(10~20%RM group, 20~30%RM group, RPE 10-12group) showed statistically meaningful improvement between period analysis and RPE 10-12 group showed statistically meaningful better improvement than 10~20%RM group.

We developed the smart 1RM system, which is composed of portable muscle strength measuring device, Bluetooth communication based mobile phone data transmission and circuit diagram, and height adjustable system body. We recruited the 30 participants with 20th aged and divided into training and non-performing groups with 15 participants randomly. The participants performed 5 sets of elbow, lumbar, knee extension / flexion 10 times using smart 1RM system and the experimental period was 3 days a week for a total of 8 weeks. The experimental results showed that the maximum strength of the elbow, lumbar, and knee joints was significantly improved before and after maximal muscle strength training in the training group. Oxygen intakes during 1RM exercise mode showed 10.91% than endurance. To verify the validity of the smart 1RM maximal strength data, the reliability was 0.895 (* p <0.00). This study can be applied to the early rehabilitation treatment of the elderly and rehabilitation patients more quantitatively using the national health care.

This study aims to analyze the influence of different intensity levels of weight training exercises at their various degrees of levels on immunity and fatigue, by measuring the changes in Immunocytes such as T and B cells, Immunoglobulin(IgA, IgG, IgM), and blood elements such as leucocyte, red cell, and blood platelet. The testes were 7 male persons of professional weight training at health clubs, and 7 male persons who have exercised weight training for less than 3 months. They exercised 50% of standard metabolic rates and 1RM and 80% of intensity, and then drew blood after exercises. The results are as the following. Among the blood elements, leucocytes(WBC) displayed a significant increase(p<.001) when the testees at the Under 3 month group and 2 year+group took exercise of 80% of the 1RM standard metabolic rates, while red cells(RBC) did not display any significant difference when the testees at the under 3 month group took exercise, and displayed a significant increase(p<.001) when the testees at the 2 year+group took exercise of 50% and 80% of the 1RM standard metabolic rates. Hemoglobin(Hb) significantly increased(p<.001) when the testees at the 2 year+group took exercise of 50% and 80% of the 1RM standard metabolic rates. 2 year+group displayed a significant increase(p<.05) than under 3 month group when they took exercise of the 1RM standard metabolic rates. Red cells(HCT) significantly increased(p<.05) when the testees at the under 3 month group took exercise of 80% of the 1RM standard metabolic rates, while displaying a significant increase(p<.001) when the testees at the 2 year+group took exercise of 50% and 80% of the 1RM standard metabolic rates. Average red cell MCV displayed a significant increase(p<.05) when the testees at the under 3 month group took exercise of and 80% of the 1RM standard metabolic rates, while displaying a significant increase(p<.05) when the testees at the 2 year+group took exercise of 50% of the 1RM standard metabolic rates. For red cell average hemoglobin, the cases of MCH displayed a significant decrease(p<.01) when the testees at the under 3 month group took exercise of 80% of the 1RM standard metabolic rates. MCHC displayed a significant decrease(p<.01) when the testees at the under 3 month group took exercise of 80% of the 1RM standard metabolic rates, while displaying a significant increase(p<.01) when the testees at the 2 year+group took exercise of 80% of the 1RM standard metabolic rates than when they took exercise of 50% of the 1RM standard metabolic rates. The testes at the 2 year+group displayed a significant increase than those at the under 3 month group when they took exercise of 50% of the 1RM standard metabolic rates, while displaying a significant increase(p<.05) when they took exercise of 80% of the 1RM standard metabolic rates. For blood platelets that act on blood coagulation, under 3 month group displayed a significant increase(p<.01) when they took exercise of 50% and 80% of the 1RM standard metabolic rates, while displaying a significant increase(p<.01) when the testes at the 2 year+group took exercise of 80% of the 1RM standard metabolic rates. Suppressor T cell(CD8) displayed a significant increase(p<.01) when the testees at the under 3 month group took exercise of 50% and 80% of the 1RM standard metabolic rates while displaying a significant decrease(p<.001) when the testees at the 2 year+group took exercise 50% and 80% of the 1RM standard metabolic rates. B cell(CD19) didn`t display any significant difference for either of the two groups. A putative subtype of B limphocytes, Immunoglobulin were inspected after classifying them into IgA, IgG, and IgM. The results are as following. IgA displayed a significant increase(p<.001) when the testees at the under 3 month group took exercise of 50% and 80% of the 1RM standard metabolic rates, while displaying a significant increase(p<.001) when the testees at the 2 year+group took exercise of 80% of the 1RM standard metabo
