The purpose of this study is to find the effects of High-Intensity Resistance Training on Muscle Growth Related Hormones, Inflammatory cytokines and Isokinetic Strength in body builders. The 25 participants were divided into rest pause set group(RPG) of 8, giant set group(GIG) of 9, and ascending set group(ASG) of 8 and they conducted assigned training 6 times a week for 12 weeks. Analysis of ANCOVA was done using SPSS 19.0 for data processing. The result of this study shows conducting ascending set is more effective than rest pause and giant on Muscle Growth Related Hormone secretion. Giant set training is effective on Isokinetic Strength, especially IL-6. Knee joint isokinectic muscle strength showed significant increase in all groups, but no significant difference among groups. Percentage body fat of body composition significantly decreased in all of 3 groups, and ASG showed more significant decrease than RPG and GIG. It is shown that even High-Intensity Resistance Training could have various change depending on training composition. However, further study will be needed adding various variables to generalize the result of this study. 본 연구는 보디빌더를 대상으로 고강도 저항훈련을 실시하여 근 성장관련호르몬, 염증성사이토카인 및 등속성 근력에 어떠한 영향을 미치는지 알아보는데 목적이 있다. 연구대상자는 남성보디빌더 25명을 대상으로 휴식-정지집단 8명, 자이언트집단 9명, 어센딩집단 8명으로 구분하여, 주 6회, 총 12주간 훈련을 실시하였다. 자료처리는 SPSS 19.0 프로그램을 이용하여 공변량 분석을 실시하였다. 연구결과 어센딩 세트가 휴식-정지 및 자이언트세트 훈련법에 비해 근 성장 관련호르몬 분비에 효과적으로 나타났다. 염증성 사이토카인은 자이언트훈련법이 효과적인 방법으로 나타났으며, 특히 IL-6의 변화에 효과적인 것으로 나타났다. 슬관절 등속성 근력은 세 집단 모두 유의하게 증가되었지만, 집단 간 유의차는 없었다. 신체구성 중 체지방률은 세 집단 모두 유의한 감소되었고, 어센딩 집단이 휴식-정지 집단과 자이언트 집단보다 유의한 감소를 나타내었다. 고강도 저항훈련이라 할지라도 훈련의 구성방법에 따라 다양한 변화가 나타날 가능성이 있는 것으로 나타났다. 하지만, 본 연구결과를 일반화시키기 위해서는 다양한 변인이 추가된 지속적 연구가 이루어져야 할 것으로 생각된다.

이삼준,김태운,박헌경,윤상윤,유안희,문은진,신동훈,조한진 대한배뇨장애요실금학회 2016 International Neurourology Journal Vol.20 No.S1

Purpose: Stress during pregnancy is a risk factor for the development of anxiety-related disorders in offspring later in life. The effects of treadmill exercise on anxiety-like behaviors and hippocampal cell proliferation were investigated using rats exposed to prenatal stress. Methods: Exposure of pregnant rats to a hunting dog in an enclosed room was used to induce stress. Anxiety-like behaviors of offspring were evaluated using the elevated plus maze test. Immunohistochemistry for the detection of 5-bromo-2ʹ- deoxyuridine and doublecortin (DCX) in the hippocampal dentate gyrus and 5-hydroxytryptamine 1A receptors (5-HT1A) in the dorsal raphe was conducted. Brain-derived neurotrophic factor (BDNF) and tyrosine kinase B (TrkB) levels in the hippocampus were evaluated by western blot analysis. Results: Offspring of maternal rats exposed to stress during pregnancy showed anxiety-like behaviors. Offspring also showed reduced expression of BDNF, TrkB, and DCX in the dentate gyrus, decreased cell proliferation in the hippocampus, and reduced 5-HT1A expression in the dorsal raphe. Postnatal treadmill exercise by offspring, but not maternal exercise during pregnancy, enhanced cell proliferation and expression of these proteins. Conclusions: Postnatal treadmill exercise ameliorated anxiety-like behaviors in offspring of stressed pregnant rats, and the alleviating effect of exercise on these behaviors is hypothesized to result from enhancement of cell proliferation through 5-HT1A activation in offspring rats.

Effects of Exercise on the Expression of 5-HT and TPH in the Raphe of Pups Born from the Learned Helplessness-induced Maternal Rats

이삼준 한국스포츠학회 2018 한국스포츠학회지 Vol.16 No.4

Negative conditions such as stress during pregnancy have negative results on the development of the pups. The level of 5-hydroxytryptamine (5-HT, serotonin) represents the neuronal activity of the brain, and this chemical plays a crucial role in shaping the development of the brain. Exercise is known to enhance both neuronal plasticity and activity in the brain. In the present study, we investigated the effects of treadmill running on the synthesis 5-HT and on the expression of tryptophan hydroxylase (TPH), the rate-limiting enzyme of 5-HT synthesis, in the dorsal raphe of the rat pups born from the learned helplessness-exposed rats during pregnancy. Our results clearly show that maternal learned helplessness exposure suppressed the synthesis of 5-HT and the expression of TPH in the dorsal raphe of rat pups, and that treadmill running enhanced the 5-HT synthesis and the TPH expression in the dorsal raphe of rat pups born from the learned helplessness-exposed rats. Based on these present results, treadmill running may be a useful strategy to enhance the neuronal activity of the children born from mothers who have exposed learned helplessness during pregnancy.

운동이 암컷 쥐의 뇌 PVT에서의 구속 스트레스로 인한 c-Fos 발현에 미치는 영향

이삼준 한국운동영양학회 2006 Physical Activity and Nutrition (Phys Act Nutr) Vol.10 No.2

The purpose of this study was to investigate differences on the expression of c-Fos IR in the PVT (thalamus paraventricular nucleus) of brain rats following restraint stress (RS) and exercise plus RS. The PVT is known to be strongly activated following a variety of stressors and thus might be suggested to play a role in stress-related information and anxiety-related disorders in the brain. However, emotional disorders according to these stress were reversed by exercise. Physical exercise also improved antidepressant and altered transcription level of various genes, which immediately early genes including c-Fos, c-Jun, and NOS etc response to stimuli, resulting in increase of neuronal activity and synaptic remodeling. Increased numbers of c-Fos immunoreactive neurons in response to stress were observed in PVT. Reduction of c-Fos immunoreactivity in the brain by supplemental exercise treatment in response to other stress protocols such as treadmill running was demonstrated. It is well known that an decrease of c-Fos expression ameliorates emotion disorder including high anxiety, arousal, and fear. In conclusion, these data indicate that treadmill exercise results in overcoming the emotional disorders via the decreased expression of c-Fos following increased emotional diseases and sensitivity of the stress axis by the restraint stress in the PVT of rat brains.

이삼준 한국스포츠학회 2013 한국스포츠학회지 Vol.11 No.3

We investigated whether the decreased cell proliferation resulting from pups born from maternal stress during pregnancy is enhanced by the treadmill exercise. It is showed that early adverse experiences-induced the dysregulation of the Ki-67 and NPY expression is reversed by exercise. Rats of stress-applied groups were exposed to a 95-desibel (dB) supersonic machine sound for 1 h, while rats of the control group were left undisturbed. The offspring were divided into six groups. Pups of the exercise groups were made to run on treadmill for 30 min once a day for 7 consecutive days. The analysis brain tissue was used by immunohistochemistry for the expression of Ki-67 and NPY. We also found that postnatal rat pups might be significant reversed by treadmill exercise on the prenatal stress-induced decrease in the hippocampal cell proliferation during pregnancy. In conclusions, we investigated that mild exercise was a better strategy to manage foe postnatal pups with early adverse stress-induces suppression of cell proliferation in prenatal stress during pregnancy

Tensiomyography를 이용한 아마추어 남자 축구선수의 장딴지근과 앞정강이근의 수축 특성 분석

이삼준,방현석,황부근 대한임상건강증진학회 2019 Korean Journal of Health Promotion Vol.19 No.2

Background: Tensiomyography (TMG) is a relatively new technique that assesses the contractile properties of muscles in response to a single electrical stimulus. This study aimed to evaluate the contractile properties of the gastrocnemius and tibialis anterior (TA) muscles in amateur soccer players using TMG. Methods: We recruited 41 male soccer players (high school group, n=21; college group, n=20). The gastrocnemius medialis (GM), gastrocnemius lateralis (GL), and TA muscles of both lower extremities were assessed using TMG. The maximal displacement (Dm), delay time, contraction time (Tc), sustained time, and half-relaxation time were obtained and compared between the two groups. Results: First, both groups showed low Dm for the GM and TA muscles, which indicated high stiffness of the muscle tone. Second, the Tc and contraction velocity (Vc) were high for all muscles, except for the GL showing lower speed than the other muscles, which represented the sports-specific characteristics of the soccer players. Third, there were no significant differences in the measurement variables between the dominant and non-dominant sides, except for the Tc of the GM in high school athletes and Vc of the TA in college athletes. Conclusions: These results reflected the sports-specific needs and characteristics of soccer players. A risk of injury is associated with a high degree of stiffness, and various methods for preventing it should be considered. 연구배경: TMG는 단일 전기자극에 대한 반응으로 근육의 수축 특성을 평가하기 위해 개발된 상대적으로 새로운평가 방법이다. 본 연구는 TMG를 이용하여 아마추어 남자축구선수의 앞정강이근과 장딴지근의 수축 특성을 살펴보고자 하였다. 방법: 총 41명(고등부 21명, 대학부 20명)의 아마추어 축구선수가 본 연구에 참여하였다. TMG는 안쪽 및 가쪽장딴지근(GM, GL)과 앞정강이근(TA)의 왼쪽과 오른쪽 모두를측정하였으며, Dm, Td, Tc, Ts, Tr을 측정하여 두 집단 간비교 및 집단 내 우세측과 비우세측 부위를 비교하였다. 결과: 첫째, 두 집단 모두 안쪽장딴지근(GM)과 앞정강이근(TA)은 Dm이 낮아 근경직도가 높은 것으로 나타났다. 둘째, 수축시간(Tc) 및 속도(Vc)는 모든 근육에서 빠르게 나타나 축구선수의 스포츠-특이적인 특성이 내재하는 것으로나타났지만 가쪽장딴지근(GL)은 다른 측정 근육에 비해 상대적으로 느렸다. 셋째, 측정 근육별 우세측과 비우세측 간에는 일부(고등부 GM-Tc, 대학부 TA-Vc)를 제외한 대부분의 측정변인에서 유의한 차이가 없었다. 결론: GM과 TA 근육에서 빠른 수축시간으로 인한 스포츠-특이적인 특성이 가지고 있다. 그러나 근경직도가 높아상해 위험성이 존재하며, 이를 예방하기 위한 다양한 방법이 강구되어야 할 것이다.
