Physical fitness, energy expenditure, and immune response of Special Forces soldiers following 400 km military march lasted 9-days were measured and these parameters were related to injury types. Ten soldiers were tested before and after the march for physical characteristics, fitness level, and blood inflammation variables. During the march, their step frequency and energy expenditure were measured and injury prevalence was monitored. Fitness and blood variables before and after the march were compared using paired t-test, and cardiovascular capacities were compared using independent t-test. No changes in body weight and composition were noticed after daily 8-hour march. After the march, adiponectin, white blood cell counts, and fibrinogen were significantly increased (p<0.05). Cardiorespiratory endurance (20 m Shuttle run), muscular strength (1 RM squat, 1RM bench press, and Sargent jump), were reduced after the march (p (0.05). No other changes in fitness variables after the march were observed. They walked more than 40,000 steps per day and spent approximately 3,400 kcal. Eight soldiers reported at least one injury incidence due to the march and recovered fully by taking medication after the march. Based on the results, reduced physical fitness in some variables and elevation of immume responses following the march may be occurred transiently mainly due to lower body injuries. Lower body injury prevention and management during the march appears to be of important concern.

본 연구는 20~30대 일반 여성 12명을 대상으로 기능성 신발과 일반 운동화의 운동역학적 비교 분석을 위해 지면반력과 압력분포를 측정하고 분석한 결과 다음과 같은 결론을 얻었다. 첫째, 제 1정점과 제 2정점에서 신발에 따른 그룹 간의 유의한 차이는 없었고, 다만 일반 운동화에 비하여 기능성 신발은 제 1정점이 상대적으로 크게 나타나 일반 운동화에 비하여 충격력이 다소 크게 받는 것으로 나타났다. 제 2정점의 추진력에서는 기능성 신발이 힘을 더 적게 받는 것으로 나타났다. 둘째, 국면별 최대압력 측정 결과 신발의 종류에 따라 이지시(국면3)에 유의한 차이가 있는 것으로 나타났다. 전체적으로 일반 운동화에 비교해 기능성 신발이 최대압력이 다소 작게 나타났다. 따라서 기능성 신발은 일반 운동화보다 후족 부위의 압력분포의 최대값이 작고 넓은 압력분포의 형태로 착지기 시 신체로 전달되는 충격의 분포가 넓게 적용되는 것으로 사료된다. The purpose of the study is to examine the effect of the spring shoe through the comparison of spring shoe with normal shoe. The following conclusions was drawn through this study (the subjects of this study were 12 healthy females in the age from 20 to 30 years) in which I use force platform and Pedar pressure distribution measure to get official approval of spring shoe and normal shoe. First, there is no significant difference caused by specific shoes among groups in the second peak and first peak point. However, spring shoe receive more shock power than normal shoe because the first peak point is relatively high. Spring shoe receive less pressure related to propulsive force of the second peak point. Second, after measuring maximum pressure in each phase, I draw the conclusion there is significant difference due to the types of shoes. Generally, maximum pressure of the spring shoe is somewhat high compared to normal shoe.

α-actinin-3는 Z disk에 위치하는 근원섬유 단백질로, α-actinin-3 유전자형(ACTN3)에 따라 α-actinin-3 단백질 생성유무가 결정된다. 특히, α-actinin-3 단백질이 백근에서만 발현된다는 점에 착안하여 국내외를 불문하고 Type IIb 근기능과 관련하여 스프린트/파워 운동수행력에 대한 ACTN3 유전자 연구가 진행되고 있다. 그러나 type IIa 근섬유의 절반가량(50%)에서도 α-actinin-3 단백질의 발현이 존재하며, type IIa의 생화학적 특성 및 근 기능적 특성을 고려할 때 α-actinin-3의 단백질 발현이 스피드/파워가 경기력의 결정요인이 되는 스프린트 종목보다는 파워지구력이 경기력의 결정요인이 되는 투기종목 또는 중거리종목에서 더 유리하게 작용할 수 있다. 따라서 본 연구는 운동종목의 특성에 따라 스프린트, 파워지구력(투기 및 중거리 종목) 및 지구력으로 세분화하여 ACTN3 다형성이 이들 특성에 미치는 영향을 알아보기 위하여 남녀 일반성인 410명과 국가대표선수 458명을 대상으로 ACTN3유전자다형성을 분석하여 그 관련성을 확인하였다. 본 연구결과에 의하면, ACTN3 RR, RX, XX형의 분포에서 스프린트(16% 32% 52%)와 일반인간(17.3% 32.2% 50.5%) ACTN3 유전자형이 유사한 분포를 보인 반면, 투기(34.3% 38.2% 27.5%, p<.001) 대 일반인, 투기 대 스프린트(p<.001), 투기 대 지구력(11.5% 32.7% 55.8%, p<.001), 그리고 중거리(29.2% 37.5% 33.3%, p<.05) 대 일반인, 중거리 대 스프린트(p<.05), 중거리 대 지구력(p<.001)간에도 유전자형 분포에서 각각 유의한 차이가 나타났다. 이러한 결과는 ACTN3 단백질 발현형(RR, RX형)을 지닌 선수들이 스프린트종목이 아닌 경기력 결정요인으로 파워지구력 또는 스피드지구력이 요구되는 투기종목 및 다양한 중거리종목들에게서 유리할 수 있음을 시사하는 것이다. The α-actinin-3 is a protein of the Z disk of myofibers, and the expression of α-actinin-3 protein is determined by ACTN3 genotype. Many researches about ACTN3 related to sprint/power performance, in particular focusing on the function of Type IIb, have been conducted because the expression of α-actinin-3 is limited to a subset of type II fibers. However, α-actinin-3 is found at the Z line of a subset of type IIb and 50 percent type IIa. Therefore, the ACTN3 RR and RX genotypes might be more related to power-endurance events than sprint/power events based on the biochemical and functional properties of type IIa muscle fiber. We investigated association between ACTN3 polymorphism, sprint and power-endurance performance in a large group of healthy people (men, n=194; women, n=212) and international level of athletes(men, n=292; women, n=166). As a result of this study, there were no significant differences in the genotypic frequencies of ACTN3 RR, RX, and XX, between the Sprint group(16%, 32%, and 52%) and CON(17.3%, 32.2%, and 50.5%). However, we determined there to be statistically significant differences in the genotypic frequencies of the genotypic frequencies of ACTN3 RR, RX, and XX, between the groups; the Martial art(34.3% 38.2% 27.5%, p<.001) vs CON, the Martial art vs the Sprint(p<.001), the Martial art vs the Endurance(p<.001), the Middle distance(29.2% 37.5% 33.3%, p<.05) vs CON, the Middle distance(29.2% 37.5% 33.3%, p<.05) vs the Sprint, Middle distance(29.2% 37.5% 33.3%, p<.05) vs Endurance(11.5% 32.7% 55.8%, p<.001), respectively, We concluded that power-endurance athletes with the RR and RX genotypes might harbor a distinct advantage over athletes with the XX genotype. Also, genetic variation in the ACTN3 gene appears to constitute a possible candidate gene, and may be useful in the selection talented young power-endurance athletes within the Korean population.

The purpose of this study was to investigate the effects of natural vitamin ingestion on acute exercise induced inflammatory factors(TNF, IL-6, CRP) and lipid peroxidation(MDA) in middle aged men with arthritis. In a randomized placebo-controlled trial, cross over design, eleven patient with light arthropathy were ingested into two treatment receiving one of the following supplements for 1 day(2 weeks apart): natural vitamin ingestion group(500ml natural vitamin mixed with apple, tomato, kiwi), placebo(500ml non-nutrient fluid). Each active men(age 45.5±5.81years) completed two maximal treadmill runs and resistance exercise(3 set with 10RM). Resistance exercise consists of leg press, leg curl, bench press, pull down, bicep curl, dumbbell kick back, sit-up, back extension. Blood samples were obtained from 30minutes after supplementation, post-exercise, and 2 hours after exercise. IL-6, CRP increased immediately and 2hours after exercise in both groups. Especially in case of CRP such exercise induced increase is grater at vitamin ingestion than placebo ingestion. Although MDA levels were similar between treatments at baseline, it increased significantly after immediately exercise and 2hours after exercise in both treatment. But no differences in the pattern of change were measured between natural vitamin ingestion and placebo trials. In conclusion, vitamin supplementation prevented endurance exercise-induced inflammatory response but had no effect on lipid peroxidation.

정동식 ( Dong Sik Joung ),이종각 ( Jong Kak Lee ),김영수 ( Young Soo Kim ),박동호 ( Dong Ho Park ),성봉주 ( Bong Joo Sung ),조남홍 ( Nam Hong Cho ),오인석 ( In Seok Oh ) 한국스포츠정책과학원(구 한국스포츠개발원) 2004 체육과학연구 Vol.15 No.3

본 연구는 저지대에서 지구력 훈련을 수행하면서 수면시간에만 저산소 환경에 노출시키는 방법을 이용하여 고지대 체류-저지대 훈련이라는 새로운 개념의 훈련 방법이 산화 스트레스와 항산화 효소에 미치는 영향을 규명하는데 그 목적이 있었다. 연구 대상은 고등학교 육상 장거리 선수 20명으로 선정하였으며, 이들을 임의로 실험집단 10명과 비교집단 10명으로 구분하였다. 실험집단은 4주 동안 3,000m 고도에 해당하는 저산소 텐트에서 하루 8시간씩 휴식 및 수면을 취하고 지구력 훈련은 저강도 장거리달리기와 고강도 인터벌 훈련을 병행하였으며 비교집단은 저산소 노출을 제외한 일체의 생활을 실험집단과 동일하게 통제하였다. 처치전 최대운동 전후와 4주간 처치후의 최대운동 전후에 산화 스트레스 및 항산화 효소 변인으로 MDA(malondialdehide) 수준, SOD(superoxide dismutase) 및 GPX(glutathione peroxidase) 활성을 측정하여 다음과 같은 결과를 얻었다. ① MDA 수준은 실험집단의 경우 처치전에는 최대운동으로 인해 증가하였으며(p<.05), 4주간처치 후에도 안정시 및 운동 후에 증가 경향을 보였으나, 처치전 최대운동 후에만 비교집단보다 유의하게 높았다(p<.05). ② SOD 활성은 실험집단의 경우 처치전에는 최대운동으로 인해 유의하게 감소(p<.05)하였고, 4주간의 처치 후에는 안정시에 처치전보다 현저한 증가(p<.05)상태를 보이고 최대운동 후에 약간 감소하는 경향을 보였으며, 처치4주 후의 안정시 및 최대운동 후에 비교집단보다 낮은 경향을 나타냈으나 최대운동 후에만 유의하게 낮은 것으로 나타났다(p<.05). ③ GPX 활성은 실험집단의 경우 처치 전에 최대운동으로 거의 변화를 나타내지 않았고 처치4주의 안정시 및 최대운동 후에는 처치전보다 현저히 증가된 상태를 보였으나(p<.05), 비교집단과 유의한 차이를 보이지는 않았다. 이상의 결과에 의하면 일시적인 최대운동은 산화 스트레스를 증가시키며 여기에 대항하는 적혈구의 SOD와 GPX의 활성을 약간 감소시키거나 변화시키지 않는 반면, 4주간의 고강도 지구력 훈련은 산화 스트레스의 증가와 이에 대응하는 SOD 및 GPX 활성의 증가를 유발하는 효과를 나타낸다고 결론 내릴 수 있다. 또한, 지구력 훈련과 병행한 3000m 고도의 저산소 노출은 산화 스트레스와 항산화 효소의 활성을 추가로 증가시키지는 않는다. The purpose of the present investigation was to determine the effects of "living high, training low" during a period of regular training on the oxidative stress and anti-oxidative enzymes. Ten long distance runners of B high school slept for 8-hour per day for 4-week at a simulated altitude of 3,000m in normobaric hypoxia (HIGH), while ten team-mates slept at the normoxia (CONDITION). HIGH and CONDITION subjects equally trained as a group throughout the 4-week study. Both baseline level(D1) and immediately after incremental exercise(DT1) test of malondialdehide(MDA), superoxide dismutase(SOD), and glutathione peroxidase(GPX) were measured 1 day prior to sleeping in hypoxia. These measures were repeated after 4-week of simulated altitude exposure before the incremental test(D2) and immediately after the test(DT2). The results were as following; ① The levels of MDA in both groups increased significantly(p<.05) after the incremental test(DT1 & DT2) in comparison to the D1 and D2, respectively. MDA levels tended to be increased above the pre-hypoxia level over 4-week of hypoxia. However, MDA level in HIGH significantly increased (p<.05) after DT1 compared to the level in CONTROL. ② The activity of SOD in both groups decreased significantly(p<.05) after the incremental test(DT1) compared to the D1. Thereafter, SOD activity tended to be increased (p<.05) above the pre-hypoxia level over 4-week of the study. However, SOD activity in HIGH significantly decreased (p<.05) after DT2 compared to MDA level in CONTROL. ③ there was no significant increase in GPX activity of both groups immediately after the test(DT1 vs D1) while GPX activity in both groups at D2 significantly decreased (p<.05) after DT2. without group difference. We concluded that acute maximal exercise might increase in oxidative stress with either increase or non-change in SOD and GPX activities. However, vigorous endurance training during 4-week might increase in oxidative stress with increase in both SOD and GPX activities. In addition, sleeping in moderate hypoxia(3,000m) with vigorous endurance training couldn`t additionally increase in both oxidative stress and anti-oxidants but appropriate method for reducing oxidative stress should be provided.

The purpose of this study was to evaluate body dissatisfaction, eating attitudes, and exercise behavior in female adolescents and to develop strategic countermeasures against those epidemic phenomenon. A total of 269 junior female high school students participated in this study, and were divided into three groups based on the body mass index (BMI); BMI<18.5: underweight (UW), 18.5-24.9: average weight (AW), and 25.0-29.9 overweight (OW), A questionnaire consisted of Body Dissatisfaction Index (BD[), Eating Attitude Test-26 (EAT26), Obesity Related Stress (ORS), and exercise behavior was administered, For the comparisons of means, one-way ANOVA was employed, and relationships between variables were assessed by correlation coefficient, For the analyses of relationship between BDI and EAT26, and physical activities, X² was utilized, The BD[ between UW and OW was significantly different (P<.05) while no differences were found in EAT26 among groups. ANOVA revealed ORS score was statistically different (P<.05), but post-hoc test did riot show any differences among groups, In each group, BMI and EAT26, and BMI and BDI were highly correlated (P<.05). However no relationships were found between BDI and EAT26. When comparing the level of physical activities among groups, no differences were found. The prevalence or inactive (less then average) was 24.7, 28.9, and 45.2% in UW, AW, and OW, respectively. The desire for exercise was 94.6, 94.5, and 100% in UW, AW, arid OW, respectively, and this was statistically different (P<.05), The perception or exercise necessity was highly rated in all groups, particularly in OW female adolescents.
