4주간의 고강도 간헐적 운동이 알파인 스키 선수의 주요 체력 요인에 미치는 영향
이지형 ( Lee Ji-heoung ),어수주 ( Eo Su-ju ),정진욱 ( Jung Jin-wook ) 한국체육대학교 체육과학연구소 2017 스포츠사이언스 Vol.34 No.2
본 연구는 알파인 스키 선수들을 대상으로 4주간의 고강도 간헐적 운동을 실시하여 알파인 스키의 경기력 향상을 위한 체력요인의 효과를 평가하고자 실시되었다. 연구 참여자는 H대학 재학 중인 경력 5년 이상의 알파인 스키선수(남: 3명, 여: 3명, 총 6명)이다. 세부적인 실험대상자의 특성은 연령(남: 20.67±0.89세, 여: 23±0.67세), 체중(남: 83±6.67kg, 여: 54.17±1.22kg), 신장(남: 179±3.33cm, 여: 158.67±2.44cm), 선수경력(남: 11.33±1.78년, 여: 11±3.33년)을 가지고 있다. 본 연구에서 실시된 4주간의 고강도 간헐적 운동 프로그램은 Mountain climbers, Lunge, Double crunches, Squat, Jumping I, Seated knee tucks, Side step, Burpee Test, Jumping II, Mountain climber의 10가지 운동으로 구성되어 있으며, 각 운동을 30초씩 실시한 후, 20초 휴식 후 다음 운동으로 진행되도록 하였다. 주 3회 운동을 실시하였고, 운동을 실시하는 날에는 오전 오후 각 3세트씩 고강도 간헐적 운동을 실시하였다. 4주간의 고강도 간헐적 운동은 알파인 선수들의 체지방률을 유의하게 감소시켰고, 등속성 근력 중 굴곡 피크토크와 등속성 근지구력 중 신전 피크토크와 굴곡 피크토크를 유의하게 향상시켰다. 또한, 민첩성을 유의하게 향상시켰고, 남자 선수들보다 여자 선수들에게 등속성 근력과 근지구력 요인에 상대적으로 더 큰 향상의 결과를 보였다. 본 연구의 결과를 통하여 경기지도자로서 알파인스키 선수들의 경기력 향상을 위한 효과적인 트레이닝 프로그램에 있어서 4주간의 고강도 간헐적 운동은 무산소성 체력 요인뿐만 아니라 유산소성 체력요인에도 긍정적인 효과성이 나타나고, 여자 알파인 선수들에게 더욱 효과성이 높을 수 있음을 알 수 있었다. The purpose of this study was to examine that the effect of four weeks High Intensity Intermittent Exercise(HIIE) on major fitness factors in Alpine ski players. Total 6 subjects(male : 3, female : 3) are elite alpine ski players in H university. Male(age : 20.67±0.89yr; weight : 83±6.67kg; height : 179±3.33cm; career : 11.33±1.78yr) and female(age : 23±0.67yr; weight : 54.17±1.22kg; height : 158.67±2.44cm; career : 11±3.33yr) players were participated HIIE(Mountain climbers, Lunge, Double crunches, Squat, Jumping I, Seated knee tucks, Side step, Burpee Test, Jumping II, Mountain climber; respectively program(30sec) and rest(20sec), 3 day/week, 2 times(3set)/day for a during of 4 weeks). The following items were measured pre and post the HIIE: body composition, wingate test, isokinetic test(muscle strength & endurance), agility(side step test). In results, %Body fat was significantly decreased but 60 flexor peak torque(isokinetic muscle strength), 240 extensor/flexor peak torque(isokinetic muscle endurance) and agility ability were significantly increased after HIIE. Most of all female players were improved more than male players in isokinetic muscle strength and endurance ability. Finally, HIIE was effective to improve sports performance(major fitness factors) in alpine ski players.

The purpose of this study was to determine shoulder pain and shoulder ultrasonographic findings in poliomyelitis Wheelchair Basketball (WB) players. Three physicians performed physical examinations and interviewed WB players about their shoulder pain by using Wheelchair User`s Shoulder Pain Index (WUSPI), Performance-Corrected WUSPI (PC-WUSPI), and Shoulder Pain and Disability Index (SPADI). One physician performed shoulder ultrasonography on WB players. All confirmed their International Wheelchair Basketball Federation (IWBF) classifications through Korean Wheelchair Basketball Federation (KWBF). Seventeen men and 6 women players were enrolled in the study, with 46 shoulders evaluated. Nine players had unilateral lower extremity weakness and 14 players were bilateral weakness. Six players used wheelchair for daily living, and 17 players used wheelchair only when playing WB. They were 44.35±5.42 years old on average. They had played WB for 11.09±9.49 years and trained 8.69±3.83 hours a week. PC-WUSPI was significantly correlated with age (p=0.014). There were no significant differences between time spent playing WB, training time for WB, types of poliomyelitis involvement, their use of wheelchair, and WUSPI, PC-WUSPI and SPADI. Tendon tear prevalence was significantly different with training time for WB (p=0.021). Most common abnormal shoulder ultrasonographic findings were subscapularis and supraspinatus tendinopathy. Tendinopathy and tendon tear prevalence did not differ significantly with age, time spent playing WB, types of poliomyelitis, and the use of wheelchair. High prevalence of shoulder pain and rotator cuff pathology were found by physical and ultrasonographic examination in the poliomyelitis wheelchair basketball players. Rotator cuff injury prevention program are needed for prevent shoulder pain and rotator cuff pathology.

The purpose of this study was to investigate the difference in cardiopulmonary endurance among positions in middle school soccer, and to identify the incidence of sports injuries in association with soccer matches and training. Ninety-six (32 forwards, 27 defenders, 29 midfielders, and eight goalkeeper [GK]) middle school soccer players (12.77±0.53 years) participated in this study. They had no medical problems. Their height, weight and body mass index (BMI) were measured, and they also went through tests for maximal oxygen consumption (VO2max). We interviewed middle school soccer players about their soccer careers and their history of sports-related injuries. Physical fitness was compared among players in different playing positions. VO2max was significantly higher in forward and defender groups than GK group. There was no significant relationship in cardiopulmonary endurance among outfield players. GK were taller and heavier than outfield players. BMI was significantly higher in GK group than midfielder group. They had played soccer for 39.08±20.28 months on average. During matches and training, forwards suffered 13 injuries (36.1%); defenders suffered 10 injuries (27.8%); midfielders suffered 12 injuries (33.3%); and only one GK came down with an injury (2.8%). The most common types of injuries were to knees (36.1%) and ankles (33.3%).
