  • Purpose: This study aimed to assess the effect of rowing ergometer training on the aerobic capacity and strength of male high school students over a 12-week period. Methods: Fourteen high school students volunteered to participate in the study. The subjects were divided into two groups: seven subjects in the experimental group and seven in the control group. The subjects in the experimental group performed rowing ergometer training for 75 min per session at three days a week for 12 weeks. The exercise intensity set the maximum heart rate (HRmax) from 40% to 80%. Aerobic capacity was measured by ventilation, cardiac output, and oxygen intake per body weight. Strength was measured by grip strength and back strength before and after training. Results: A significantly increased ventilation (p=0.01), cardiac output (p=0.01), and oxygen intake per body weight (p=0.00) were found in the experimental group. A significantly increased grip strength in the right and left hands (p=0.00, 0.00) and back strength (p=0.04) were observed in the experimental group. Conclusion: Rowing ergometer training can be an effective combined exercise for aerobic capacity and strength of high school students.

  • The purpose of this study was (a)to compare electromyographic (EMG) activities and physiological variables on the development of fatigue induced by ergometer test, (b)to determine investigate the differences in the stage of fatigue between the electromyographic characteristics and physiological variables. Nine male university students who have no musculoskeletal disorder were recruited as the subjects. The electromyographic characteristics(peak IEMG, average IEMG, median frequency, mean edge frequency) and physiological variables(HR, RPE, blood lactate) were determined for each stage(15, 30, 45, 60 minutes, all out). For each dependent variable, one-way analysis of variance(ANOVA) with repeated measures and correlation analysis were performed to test if significant difference existed(p<.05). The results showed that peak IEMG, average IEMG from low extremity and physiological variables were significantly increased during the all-out stage. EMG parameters in VL, VM show significantly correlation with physiological variables during whole stages. This indicated that IEMG values may be proper parameters to determine muscle fatigue rather than physiological variables.

  • The purpose of this study was to investigate the muscle mechanical properties of the pelvic axial pre-rotational movement for the Jireugi in the Taekwondo Juchumseogi stance. Eleven elite Taekwondo Poomsae athletes participated. Each participant performed 5 right hand Jireugi in Juchumseogi stance as fast and strong as possible while their motion was recorded by a 3D motion analysis system and the ground reaction forces by two force plates. The power and work of the muscular group surrounding the waist were analyzed to verify the effect of the stretch-shortening cycle (SSC) theory. The cause of the greater power seems to be the application of the SSC by the muscles surrounding the waist during the preparation phase of the pre-rotation group. For the none pre-rotation group, they only used the concentric contraction of the muscles surrounding the waist. Because the pre-rotation group used the SSC theory, they had the effect of shortening of the range of movement, creating a fast and more powerful rotation, thus anticipating the increase the magnitude of impact.

  • 체육전공에서 해부학을 통해 스포츠 상해, 운동역학적 적용, 인체의 병리나 생리적인 지식을 습득할 수 있는 바탕이 된다. 그러므로 해부학적 기초가 없이 운동생리학, 생체역학, 측정평가, 운동처방 등 여러 응용학문에 대한 이해가 불가능하다. 대부분 체육전공에서 해부학을 전공필수로 지정하여 그 중요성을 강조하고 있다. 체육전공학과는 학과특성 및 교육시설 등 여러 가지 문제로 인해 해부학 실습교육이 어렵고, 특히 체육 특기생 경우 잦은 시합으로 수업의 결손이 많다. 또한 체육학과 전공교수는 학과특성상 대부분이 체육전공자로서 최근 의과대학에서 해부학을 포함한 기초의학전공 교수들의 감소되는 현상으로 건강-의료-보건관련 학과의 기초의학강의의 수요를 충족시키는데 어려움이 존재하여 학과 내 해부학강의도 체육전공교수들이 직접하고 있는 실정이다. 기초의학전공자가 아닌 교원의 해부학강의는 깊이 있는 해부학지식을 전달하는데 제한적이며 교수의 강의에 대한 부담도 존재한다. 따라서 본 연구는 2007년부터 2009년 동안 강원대학교 스포츠과학부 학생들을 대상으로 자체 제작한 가상강의 컨텐츠와 해부실습, 그리고 면대면 강의를 병행한 혼합강의를 실시한 후 설문조사를 통해 체육전공학생들의 효과적인 해부학지식전달의 방식으로 그 도입을 제시하고자 한다.

  • The purpose of this study was to analyze the changes in kinematic and kinetic parameters of lower extremity joint according to rehabilitation period. Fourteen collegiate male athletes(age: $22.1{\pm}1.35$ years, height: $182.46{\pm}9.45cm$, weight: $88.63{\pm}9.25kg$) and fourteen collegiate athletes on functional ankle instability(age: $21.5{\pm}1.35$ years, height: $184.45{\pm}9.42cm$, weight: $92.85{\pm}10.85kg$) with the right leg as dominant were chosen. The subjects performed drop landing. The date were collected by using VICON with 8 camera to analyze kinematic variables and force platform to analyze kinetic variables. There are two approaches of this study, one is to compare between groups, the other is to find changes of lower extremity joint after rehabilitation. In comparison to the control group, FAI group showed more increased PF & Inversion at IC and decreased full ROM when drop landing. Regarding the peak force and loading rate, it resulted in higher PVGRF and loading. FAI group used more increased knee and hip ROM because of decreased ankle ROM to absorb the shock. And it used sagittal movement to stabilize. In terms of rehabilitation period, FAI group showed that landing patterns were changed and it increased total ankle excursion and used all lower extremity joint close to normal ankle. Regarding the peak force and loading rate, FAI group decreased PVGRF and loading rate. and also showed shock absorption using increased ankle movement. And COP variable showed that proprioception training increased stability during 8 weeks. The results of this study suggest that 8 weeks rehabilitation period is worthwhile to be considered as a way to improve neuromuscular control and to prevent sports injuries.

  • The purpose of the present study was to examine effect of 12 week regular aerobic exercise on ST-segment and QTc interval in middle age type 2 diabetes mellitus (T2DM) patients. The subjects consist of 13 type 2 diabetes mellitus (T2DM) patients in middle age men and all of them had no other complications. Subjects participated in aerobic exercise training for 12 weeks. They started to exercise for $20{\sim}60$ min at $60{\sim}80%$ of $HR_{max}$, (exercise intensity has been increased gradually) per day, $3{\sim}5$ times a week. The results were compared before and after. Weight and BMI, % body fat, fasting glucose, HOMA-IR, $_{peak}DBP$ were significantly decreased and $_{peak}HR$, $_{peak}VO_2$, exercisre time were significantly increased after 12 week aerobic exercise. Also, QTc interval and ST-segment were significantly decreased during at rest, peak exercise after 12 week aerobic exercise. Conclusionally, 12 week aerobic exercise may be improvement in decreased cardiovascular mortality factors (ST-segment) and abnormal autonomic dysfunction (QTc interval) and potentially increased exercise capacity.

  • This study examined the effects of different performance sequences of aerobic and strength exercises for 10 weeks on the body composition, physical function, and hormones in males aged in their 20s. A total of 30 subjects (N=30) were assigned randomly to either aerobic and resistance exercise (n=10, A+R), resistance and aerobic exercise (n=10, R+A), or a control group (n=10, CON). The different order of aerobic (HRmax 50-80%, 30 min) and resistance (50-80% 1RM, 30 min) exercises for 10 weeks was consisted of 3 times per week and 80 minutes per session. The body composition, physical function, and hormones were measured before and after the training period. The lean body mass (p=.015) was increased and the fat mass (p=.042) and % body fat (p=.007) in the A+R were decreased. The skeletal muscle mass (p=.001) in the R+A was increased and % body fat was decreased (p=.003). The weight (p=.03) and % body fat (p=.039) in the CON were increased. The aerobic capacity (p=.011) and muscular endurance (p=.001) in the A+R group were improved. The muscular endurance (p=.0016) in the R+A was improved. The epinephrine (p=.048), norepinephrine (p=.013), and cortisol (p=.045) levels in the A+R group were increased. The epinephrine (p=.046) level in the R+A group was increased. The insulin (p=.007) level increased in the CON group. In conclusion, both A+R and R+A groups produced superior results to the CON group but the A+R group was slightly more efficient than the R+A group.
