  • 심폐 지구력은 유전인자에 의해 부분적으로 결정되며, 현재까지 이루어진 연구 결과에 의하면 안지오텐신 전환효소 유전자에 존재하는 다형성과 이 형질 사이에 유의한 관련성이 보고되고 있다. 그러나, 이러한 연구는 주로 서양인을 대상으로 수행되었기 때문에 유전적 배경이 다른 아시아 집단에 대해서는 아직까지 이렇다 할 연구 성과가 없는 실정이다. 이에, 본 연구에서는 아시아 집단중에서도 민족적으로 순수한 한국인 집단을 대상으로 안지오텐신 전환효소 유전자에 존재하는 다향성이 한국인 집단에서도 심폐 지구력과 유의한 관련성이 있는 지를 조사하였다. 그러나, 한국인 운동선수군을 대상으로 한 연구에서는 안지오텐신 전환효소 유전자의 다향성이 심폐 지구력을 비롯한 신체 계측치 및 생화학적인 측정치 들과 어떠한 관련성도 나타내지 않았다(P<0.05). 그러나, 본 연구 대상으로 다양한 종목에서 선발된 운동선수들을 표본으로 하였기 때문에, 단일 종목의 운동 선수군을 대상으로 한 추시가 요구된다.

  • Aerobic capacity is an important health indicator which is related to the probability of disease, disability, and mortality. Typically, endurance exercise is known as the primary method of improving aerobic capacity. Although most of resistance exercises are not considered for a good method increasing aerobic capacity, low to moderate intensity resistance exercise with short rest periods may improve aerobic capacity, especially old adults and most low to moderate risk patients suffering from CAD. This review is to understand that a number of physiological changes occur during both aerobic and resistance exercise, and to support that resistance exercise has advantages for improving aerobic capacity.

  • 본 연구는 전방머리자세 대학생을 대상으로 목뼈안정화운동이 머리뼈척추각, 깊은목굽힘근 지구력 및 뒤통수밑근 근긴장도의 변화를 알아보고자 하였다. 이 연구 결과 CSEG에서 CVA, DNFET에서 유의하게 증가하였으며 뒤통수근 근긴장도에서는 경직도에서만 유의하게 감소하였다. 목뼈 안정화운동은 목뼈의 중립자세를 유지하면서 깊은목 굽힘근 활성화되고 근지구력이 향상되었으며, 턱을 당기는 동작으로 튀통수근의 경직이 감소한 것으로 생각된다. 또한 지구력 증가시키고 근 긴장도에 감소는 통증을 조절함에 있어서도 도움이 될 것이다. 따라서 목뼈안정화운동은 깊은목굽힘근과 뒤통수근의 개선을 위한 중재방법임을 확인할 수 있었으며, 전방머리자세 예방하기 위해 필요할 것으로 생각된다.

  • The effects of dietary supplementation of JR-22, formula containing distilled extracts of traditional herbs on maximal exercise performance and endurance were evaluated in mouse and rat model. In acute forced swimming test with 4%∼8% of the body weight attached to the tail, it was shown that dietary JR-22 supplementation increased endurance in exercise performance. There was no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity, however ATP concentration in muscle was increased by JR-22 supplementation. Also, insulin-like growth factor-l (IGF-1) concentration in blood was significantly increased by JR-22 supplementation. In addition, the oxidative damage induced by exercise was reduced by JR-22 supplementation. In these results, we suggested that JR-22 supplementation enhanced maximal endurance exercise performance by the mechanism of increasing ATP and IGF-1 concentration and reducing oxidative damage.

  • Endurance time is very important indicator to estimate muscle fatigue. In the case of measuring endurance time directly, it is dangerous for subject to perform a test until the point of failure to main time force. Therefore, this paper presents the model to estimate endirance time using indirect measurements such as personal factors and anthropometrical data. Previous studies had shown that personal factors such as gender and age were not related to endurance time, but recently studies have shown that it is estimated by using independent variable or predictor such as GTA (Gravitational Torque of the horizontal, stretched arm) and MVC (Maximum Voluntary Contraction). The present study investigated variables to estimate endurance time using personal factors and anthrometrical data during isotonic contractions. Twenty five healthy subject volunteered for this study, and performed three test sessions of isotonic contraction exercises at 10~50% respectively. Afterward the correlation coefficient and p-values were compared among regression models using personal factors and anthropometrical data. The results demonstrated that multi-regression model had significant coefficient of correlation, and was useful estimate endurance time.

  • The effect on strength and endurance training (SET) (2 patients) were compared with those of strength training(ST) (2 patients) in patients with-chronic obstructive pulmonary disease. The result of training was assessed by 4 tests: maximal inspiratory pressure(PImax), sustainable inspiratory pressure (SIP), maximal voluntary ventiiation(MVV) and bronchitis-emphysema symptom checklist(BESC). Measurements were repeated before and after training per week for 6 weeks. The SET group performed inspiratory muscle training, using a inspiratory muscle trainer 30 minutes per day, 6 days per week and performing endurance training-12-minute walking-2 days per week for 6 weeks, whereas the ST-only group trained for 30 minutes daily, 6 days per week using inspiratory muscle trainer. SET was no significant increase in exercise performance, whereas ST produced an increase in SIP and a decrease in BESC. There was significant change in BESC betweet the two groups. A simple at home training program using inspiartory muscle trainer was more effective than that of SET program in improving exercise performance of some patients with COPD.h COPD.

  • The purpose of this study was to identify cervical stabilized exercise and joint mobilization, the difference between them, and the maximum muscle strength and static muscle endurance of each group after the enforcement to general people. Cervical joint mobilization group refers to interarticular exercise (traction, pressure, glide) using with Kaltenborn technique. 3 classes were divided into 20 people each, cervical joint mobilization and stabilized exercise, and the comparison groups were randomized for the study. Both cervical stabilized exercise and joint mobilization increased maximum muscle strength and static muscle endurance. Patients should be able improve muscle stabilization and deep cervical muscle by using joint mobilization when the patient is unable to exercise on their own.

  • The purpose of this study is to compare the difference between quadriceps strength and endurance on the degree of elasticity of convergent kinesio taping. Twenty-eight normal adults who voluntarily participated in this study were randomly assigned among 4 groups, that is, group without tape, group with tape elasticity of 0 %, group with tape elasticity of 25 %, or group with tape elasticity of 50 %. Quadriceps strength and endurance were measured using CSMI. Strength among the groups was significantly different (p<.001), and the greater the elasticity of the tape, the greater the muscle strength. However, endurance was't significantly different among the groups (p>.05). These findings suggest that convergent kinesio taping elasticity with 25% and 50% is effective for quadriceps strength in physical activity.

  • The purpose of this study was to evaluate the effects of a 14-week proprioceptive resistance exercise on muscle endurance strength, dynamic balance and gait ability of elderly women in a social welfare facility. Thirty community dwelling elderly subjects (mean age 70.84±3.33) divided into experimental (n=15) and control (n=15) groups. The participants performed the muscle endurance strength(30sec hair stand), dynamic balance (3m up and go) and low extremity performance (10m walking, 400m walking) pre and after the training program. The exercise groups were submitted to 14 weeks proprioceptive training with a Swiss ball three times a week. As a results were as follow. Significantly improvements were observed in low extremity strength and dynamic balance. And there have significantly improvements in 10m walking, 400m walking. Conclusionly, the improvement of dynamic balance and gait ability by proprioceptive resistance training will reduce the possibility in female elderly people.
