Linear과 Non-Linear 주기화 근력트레이닝에 따른 카바디 선수의 신체구성, 최대근력 및 근파워의 차이 비교
라효상 ( Hyo Sang Ra ),윤영학 ( Young Hak Yoon ),조재기 ( Jae Kee Cho ),윤성진 ( Sung Jin Yoon ) 한국스포츠정책과학원(구 한국스포츠개발원) 2012 체육과학연구 Vol.23 No.3
이 연구는 Linear(선형)과 Non-linear(비선형)로 주기화된 근력트레이닝이 카바디 선수의 신체구성, 최대근력 및 근파워에 미치는 영향을 규명하여 근력과 근파워가 주 체력요인인 운동선수에게 있어 효과적인 주기화 근력트레이닝 방법을 제시하고 카바디 선수의 경기력 향상을 도모하는데 그 목적이 있다. 연구 대상은 D대학교에서 합숙훈련중인 카바디 국대대표 상비군선수 14명을 선정하였으며 이들을 임의로 선형 주기화(Linear Periodization, LP; 7명) 집단과 비선형 주기화(Non-Linear Periodization, NLP; 7명) 집단으로 구분하였다. 두 집단은 15주 동안 주 3회의 근력트레이닝을 실시하였으며 추가되는 운동량에 의해 수행력이 개선되는 영향을 최소화하기 위해 두 집단의 근력트레이닝 총 운동량을 동일하게 구성하였다. 두 집단의 유일한 차이점은 운동강도와 운동량이 5주(LP 집단)또는 일(NLP 집단)단위로 변화한다는 점이다. 15주간의 근력트레이닝을 실시하기전과 후에 신체구성, 벤치프레스 1RM, 스쿼트 1RM, 스쿼트점프, 반동점프, 메디신볼 던지기를 측정하였으며 자료분석은 SPSS 18.0 프로그램을 이용하여 반복측정 분산분석(repeated measured ANOVA)을 실시하였다. 분석결과 집단간에 통계적으로 유의한 차이는 나타나지 않았지만 LP 집단은 벤치프레스 1RM, 스쿼트 1RM, 메디신볼 던지기, 스쿼트점프 도약고, 반동점프 도약고에서 NLP 집단보다 높은 증가율을 보였다. 결론적으로 LP 근력트레이닝 방법은 근력과 근파워가 주 체력요인이며 하나의 시합목표를 가지고 최대단계에 집중하는 종목에 보다 적합한 주기화 근력트레이닝방법이라고 생각되며 지속적으로 고강도 훈련을 하는 운동선수에게 있어 장기적인 트레이닝 적응과 발달을 위해서는 무엇보다 주기화 트레이닝 방법에서 총 운동량의 조절과 함께 회복에 대한 적극적인 고려가 이루어져야 할 것으로 생각된다. The purpose of this study was determine the effects of Linear periodized strength training compared with Non-linear periodized strength training on body composition, maximal strength, muscular power and suggests that which periodized strength training is more effective for the athletes based on training for maximal muscular strength and muscular power. Fourteen the international Kabaddi players who stay in D university`s camp for training were chosen and they were divided into two groups (Linear Periodization, LP:7, Non-Periodization, NP:7). Both groups are performed strength training 3 times a week for 15 weeks and total work volume was matched. Only difference between both groups is exercise-intensity and altered 5week (LP group) or a day unit (NLP group). The changes of body composition, maximal strength (1RM bench press, 1RM squat), and muscular power (squat jump, countermovement jump) were measured before and after 15weeks periodized strength training and the results were as follows. Data showed that LP group is higher increase rate than NP group in bench press and squat 1RM, medicine ball throw, squat jump and countermovement jump height but pre and post training between LP group and NP group, there was no significance. From these results Linear strength training method is more effective periodization strength training method to improve maximal muscular strength and muscular power than Non-linear strength training method in Kabaddi players and suggested that it is proper periodization strength training for sport type which is needed maximal concentration phase. It is also suggested that total exercise volume and recovery are actively concerned for players who perform continuously high intensity training for long-term training adaptation and development.

수영선수의 shot fin 훈련이 하지근력 및 기록에 미치는 영향
윤영학 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.20 No.1
The purpose of this study was to investigate the effect of short fin training on performance in swimmers. Subjects as an experimental group were seven well-trained female collegial swimmers, they were trained by swimming with short fin. Control group was composed of seven well-trained collegial female swimmers .who taking normal swimming training. 1. VO₂max was found to have a significant increase by 9.9% in experimental group. 2. Peak torque of left leg extensor in 60˚/sec were found to have a significant increase both groups. 3. The records of 200m crawl were found to the improvement, but to have no significance in the control group. While those of 200m crawl were also found to have the improvement, significantly (p<.05). The records of crawl ith only kick were found to have the improvement in the control group, but to have no significance. While those of crawl with only dick were also found to have the improvement, significantly, in the experimental group. As the above, the results of training groups taken on short fin were found to have a great increase in VO₂max, each leg extensor both left and right, and the peak torque of extension in 60˚/sec both right and left legs. Because of the results, the record was found to have the improvement in crawl and crawl with only kick.

중년 여성의 12주간 걷기 운동이 면역 기능에 미치는 영향
윤영학 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.20 No.1
The purpose of this study was to investigate immune reaction after 12weeks walking training in middle-aged women. Subjects were seven healthy middle-aged women who not taking any particular physical training. VO₂max was determined for each subject by administering a treadmill exercise test(0% slope, start speed 80m/min, increased 20m/min each 2min). Training protocol were composed of warming up(10min), treadmill 6㎞ walking (80m/min, 75min, 4 frequancy/week) and cooling down(10min). Paired t-test was used to evaluate the difference of pre and post aerobic training. The 0.05 level of significance was as critical level for the study. The results of this study are as follows ; 1. Body weight and %fat were decreared, VO₂inax and VO₂max/㎏ were increared after 12weeks walking training. 2. WBC, lymphocyte, T lymphocyte, Th, Th/Ts were significantly increased but Ts was decreased after 12weeks training. We concluded: After 12weeks walking training, Th was increased, while Ts was decreased. So Th/Ts ratio was elevated. It means that immune function was improved.

유산소성운동이 폐경기 여성의 골밀도 및 지질대사에 미치는 영향
김영준,윤영학 대한스포츠의학회 1999 대한스포츠의학회지 Vol.17 No.2
This study was designed to investigate the effects of aerobic exercise for 16weeks on bone mineral density(BMD) and lipid metabolism in postmenopausal women. The subjects were healthy density(BMD) and lipid metabolism in postmenopausal women. The subjects were healthy 30 women aged from 45 to 57 years old. They were divided into four groups; mountain-climbing, swimming, aerobic dance and control group. Each group was tested bone mineral density and lipids before and after a 16 weeks exercise program, consisting of 50min of an aerobic activity at 60-75% of maximum heart rate(HRmax). 5times per weeks Bone mineral density were measured by dual energy x-ray absorptiometry(DEXA). BMD measurement item were the lumbar 2-4, ward' triangle, trochanteric and fermur neck. Lipid measurement item were Triglyceride. Total-cholesterol was no significant difference in pre and post aerobic exercise. HDL-cholesterol was significantly increased in swimming and aerobic dance group.
