김은숙,김도현,윤성진 한국체육학회 2024 한국체육학회지 Vol.63 No.2

본 연구에서는 일회성 중등강도 유산소운동과 열 침수 순서가 비만 성인의 HSP72, 염증 반응 및 혈중 지질에 미치는 영향을 검증하고자 하였다. 연구대상자는 비만 성인 10명을 모집하여(남성 6명, 여성 4명), 중등강도 유산소운동 후 열 침수(moderate-intensity aerobic exercise after hot water immersion: EAH)와 열 침수 후 중등강도 유산소운동(hot water immersion after moderate-intensity aerobic exercise: HAE) 처치를 단일 집단 교차연구 설계로 진행하였다. 처치 중 RPE와체온을 측정하였으며(20분마다), 각 처치 전, 직후, 2시간 후, 6시간 후에 혈액샘플(HSP72,TNF-α, CK, hs-CRP, TG, TC, HDL-C, LDL-C)을 채취하여 분석하였다. 본 연구의 결과, RPE는 EAH에서 HAE보다 처치 60분 후, 직후 유의하게 낮게 나타났다. HSP72는 EAH와 HAE에서 모두 직후, 2시간 후 사전보다 유의하게 높게 나타났으며, 6시간 후에는 EAH에서만 유의하게높게 나타났다. TNF-α는 EAH와 HAE에서 모두 직후 사전보다 유의하게 높게 나타났으며, 2시간 후, 6시간 후에는 유의한 차이가 나타나지 않았다. CK는 EAH와 HAE에서 모두 직후 사전보다 유의하게 높게 나타났으며, EAH에서 HAE보다 2시간 후, 6시간 후 낮게 나타났다. TG는 EAH와 HAE에서 모두 직후, 2시간 후, 6시간 후에 사전보다 유의하게 낮게 나타났다. 따라서, 중등강도 유산소운동 후 열 침수가 비만 성인의 RPE, HSP72, 염증 반응 개선에 더 효과적이었으며, 중등강도 유산소운동 후열 침수와 열 침수 후 중등강도 유산소운동 처치 모두 혈중 지질에 긍정적인 변화를 유도할 수 있음을 시사한다. The purpose of this study was to investigate the effects of different sequences of acute moderate-intensity aerobic exercise and hot water immersion on HSP72, inflammatory response and blood lipids in obese adults. The participants were recruited from ten obese people (6 male and 4 female), and moderate-intensity aerobic exercise after hot water immersion (EAH) and hot water immersion after moderate-intensity aerobic exercise (HAE) treatments were conducted in a single-group crossover study design.RPE and body temperature were measured during treatment (every 20 minutes), and blood samples (HSP72, TNF-α, CK, hs-CRP, TG, TC, HDL-C, LDL-C) was collected and analyzed. As a result of this study, RPE was significantly lower in EAH than in HAE at 60 min during treatment, immediately after treatment. HSP72 was significantly higher immediately after treatment and after 2 hours in both EAH and HAE than pre, and was significantly higher only in EAH after 6 hours. TNF-α was significantly higher immediately after treatment in both EAH and HAE than pre, and there was no significant difference after 2 hours and 6 hours. CK was significantly higher immediately after treatment in both EAH and HAE than pre, and lower in EAH at after 2 hours and after 6 hours than in HAE. TG was significantly lower immediately after treatment, after 2 hours and 6 hours in both EAH and HAE than pre. Therefore, moderate-intensity aerobic exercise after hot water immersion was more effective in improving RPE, HSP72, and inflammatory responses in obese adults, and both moderate-intensity aerobic exercise after hot water immersion and hot water immersion after moderate-intensity aerobic exercise could induce positive changes in blood lipids.

Moderate-Intensity Exercise Preserves Bone Mineral Density and Improves Femoral Trabecular Bone Microarchitecture in Middle-Aged Mice

Seungyong Lee,Yun-A Shin,Jinkyung Cho,Dong-Ho Park,Changsun Kim 대한골대사학회 2022 대한골대사학회지 Vol.29 No.2

Background: Aging leads to significant bone loss and elevated osteoporosis risk. Exercise slows age-related bone loss; however, the effects of various moderate-intensity exercise training volumes on bone metabolism remain unclear. This study aimed to determine the degree to which different volumes of moderate-intensity aerobic exercise training influence bone mineral density (BMD), bone mineral content (BMC), femoral trabecular bone microarchitecture, and cortical bone in middle-aged mice. Methods: Twenty middle-aged male C57BL/6 mice were randomly assigned 8 weeks of either (1) non-exercise (CON); (2) moderate-intensity with high-volume exercise (EX_MHV); or (3) moderate-intensity with low-volume exercise (EX_MLV) (N=6-7, respectively). Femoral BMD and BMC were evaluated using dual energy X-ray absorptiometry, and trabecular and cortical bone were measured using micro-computed tomography. Results: Femoral BMD in EX_MHV but not EX_MLV was significantly higher (P<0.05) than in CON. The distal femoral fractional trabecular bone volume/tissue volume (BV/TV, %) was significantly higher (P<0.05) in both EX_MHV and EX_MLV than in CON mice. Increased BV/TV was induced by significantly increased trabecular thickness (mm) and tended to be higher (P<0.10) in BV (mm3) and lower in trabecular separation (mm) in EX_MHV and EX_MLV than in CON. The femoral mid-diaphysis cortical bone was stronger in EX_MLV than EX_MHV. Conclusions: Long-term moderate-intensity aerobic exercise with low to high volumes can be thought to have a positive effect on hindlimb BMD and attenuate age-associated trabecular bone loss in the femur. Moderate-intensity aerobic exercise may be an effective and applicable exercise regimen to prevent age-related loss of BMD and BV.

최재일(ChoiJaeil) 한국체육학회 2019 한국체육학회지 Vol.58 No.4

이 연구는 비활동 여성 30명을 대상으로 중강도 지속 운동(moderate-intensity continuous exercise; MICE)과 고강도 인터벌 운동(high-intensity interval exercise; HIIE) 시 감정적 반응과 신경전달물질의 차이를 규명하기 위해 실시되었다. 두 집단 모두 설계된 일회성 트레드밀 운동을 실시하였고, 동일한 운동을 1주일 간격으로 총 3회 반복 실시하였다. MICE는 환기역치(VT) 50% 수준에서 5분간 준비운동 후 90%VT 수준에서 25분간 지속운동을 실시하였고 다시 50%VT 수준에서 5분간 정리운동을 실시하였다. HIIE는 115%VT 수준에서 2분간 6회 반복하였고, 중간의 운동성 회복은 85%VT 수준에서 2분간 4회 반복하였다. 통계분석결과 MICE는 첫 번째 실험에서 운동 중 감정반응과 운동 후 즐거움에 대해 긍정적으로 나타났지만 세 번째 실험에서는 부정적으로 나타났다. 반대로 HIIE는 첫 번째 실험에서 운동 중 감정반응과 운동후 즐거움에 대해 부정적으로 나타났지만 세 번째 실험에서는 긍정적으로 나타났다. 신경전달물질의 경우 3번의 실험에서 두 집단 모두 운동전에 비해 운동 10분 후 유의하게 증가한 것으로 나타났다. 종합해볼 때 비활동 여성에게 HIIE 운동이 운동순응을 높이는 전략이 될 수 있다고 판단된다. This study was conducted to investigate the differences between emotional responses and neurotransmitters in moderate-intensity continuous exercise (MICE) and high-intensity interval exercise (HIIE) in 30 low-active women. Both groups performed a designed acute treadmill exercise and repeated the same exercise three times at intervals of one week. MICE performed a 25-minute continuous exercise at 90% VT(ventilation threshold) after a 5-minute warm-up session at 50% VT and then cooled down for 5 minutes at 50% VT level. The HIIE was repeated 6 times for 2 minutes at 115% VT level, and the intermediate active recovery was repeated 4 times for 2 minutes at 85% VT level. The results of the statistical analysis are as follows. MICE was showed positive effect for feeling scale and PACES after exercise in the first experiment, but negative effect in the third experiment. Conversely, HIIE was showed negative effect for feeling scale and PACES after exercise in the first experiment, but positive effect in the third experiment. Neurotransmitters were significantly increased in all three groups after 10 minutes of exercise compared to before exercise. In summary, HIIE exercise may be a strategy to increase exercise compliance for low-active women.

The purpose of this study was to analyze the aerobic fitness and myocardial oxygen uptake according to the training method for spinal cord injury. As the training method, high intensity interval training and moderate intensity continuous training were applied. As the training method, high-intensity interval training and moderate-intensity continuous training were applied. and the subjects of the study were selected as men with spinal cord injury. The recruited subjects were randomly assigned to a high intensity interval training group (n=8) and a moderate intensity continuous training group (n=8) to form a group, and training was conducted for 8 weeks. In the case of aerobic fitness, there was a significant difference in the high-intensity interval training group (p<.001), myocardial oxygen uptake did not show a significant effect. In conclusion, high intensity interval training is expected to be effective training method for spinal cord injury because it can expect time saving along with the effect of cardiopulmonary fitness. In order to effect myocardial oxygen uptake, it is necessary to apply detailed training through analysis of physical factors along with the level of damage of the subjects. 본 연구는 척수장애인을 대상으로 트레이닝 방법에 따라 유산소 체력과 심근산소소비량을 분석하고자 하였다. 트레이닝 방법은 고강도 인터벌 트레이닝과 중강도 지속성 트레이닝을 적용하였으며, 연구대상은 남성 하지마비 척수장애인으로 선정하였다. 모집된 대상자를 고강도 인터벌 트레이닝 집단(n=8), 중강도 지속성 트레이닝 집단(n=8)으로 무작위로 배정하여 집단을 구성하였으며 8주간 트레이닝을 실시하였다. 유산소체력의 경우 고강도 인터벌 트레이닝 집단에서 유의한 차이가 나타났으며(p<.001), 심근산소소비량은 유의한 효과가 나타나지 않았다. 결론적으로 고강도 인터벌 트레이닝이 심폐체력의 효과와 더불어 시간적 절약을 기대할 수 있기 때문에 척수장애인에게 효과적인 트레이닝 방법이라 생각되며, 심근산소소비량의 효과를 위해서는 대상자의 손상수준과 더불어 체력적 요인의 분석을 통한 세밀한 트레이닝 적용이 필요할 것이라 사료된다.

점증적 최대부하운동 및 중,고강도운동시 혈장아미노산 농도의 변화

나재철 ( Na Jae Cheol ) 한국운동영양학회 2003 Physical Activity and Nutrition (Phys Act Nutr) Vol.7 No.3

The purpose of this study was to examine the changes of plasma amino acid concentrations during gradual maximum exercise and moderate to high intensity exercise with male collegians. Plasma EAA concentrations showed an increase immediately after three different exercise intensify. Plasma NEAA and TAA concentrations revealed a slight decrease in 60% VO_(2)max (30 min). In contrast, They demonstrated an increase in two different exercise intensity and recovery phase. As compared to pre-exercise, plasma amino acid concentrations of post-exercise in gradual maximum exercise were decreased in valine (-2%), ornithine (-2%). proline (-1%), citruline (-8%) and 3-methylhistidine (-3%). As compared to pre-exercise, threonine (-4% ), valnine (-5%). methionine (-2%), taurine (-25%), ornithine (-3%), serine(-3%), asparagine (-2%), glutamine (-9%), proline (-3%). glycine (-15%), citruline (-42%). histidine (-7%). 3-methylhistidine (-7%) and arginine (-0.5% ) were decreased immediately after moderate intensity exercise. As compared to pre-exercise, taurine (-11%), glycine (-2%) and 3-methylhistidine (-15%) were decreased immediately after high intensity exercise. BCAA, BAA, LNAA and AAA concentrations showed an increase. whereas SCAA concentrations revealed a decrease after three different exercise intensity. As a result. It could be regarded that three different exercise intensity dole not cause an imbalnace of plasma amino acid concentrations. However, in light of an increased AAA/BCAA and Trp/BCAA ratio, it was inferred that a development of central fstigue after exercise could be possible.

Abdossaleh Zar,Fatemeh Ahmadi,Maryamosadat Miri,Hassan Ali Abedi,Mohsen Salesi 대한면역학회 2016 Immune Network Vol.16 No.2

To find the relation between exercise and cytokines, we examined the effect of the training intensity on the levels of cytokines, including interferon-gamma (IFN-γ), interlukine- 4 (IL-4) and interlukine-4/interferon-gamma ratio (IL-4/IFN-γ ratio) in female Futsal players. Twelve well-trained female college Futsal players aged 19∼22 participated in this study. The athletes completed 30-min of running at 60∼65% maximal heart rate [moderate-intensity exercise], and 30-min of running at 75∼80% maximal heart rate [high-intensity exercise]. peripheral blood samples were collected 24 h before and 24 h and 48 h after each of the exercise bouts. finding showed that The 30-min bout of moderate-intensity exercise induced a significant increase in IFN-γ (p=0.01) and significant decreases in IL-4 (p=0.001) and IL-4/IFN-γ ratio (p=0.003). And also, 30-min of running at 75∼80% maximal heart rate induced increase in IFN-γ (p=0.07) and decreased in IL-4 (p=0.01) and IL-4/IFN-γ ratio (p=0.06) that these changes not significantly. In summary, exercise intensity can effect on the magnitude of changes in cytokines. It seems that moderate intensity exercise enhances cytokine pattern in female college Futsal players.

Postural Sway Response to Exercise: The Effect of Intensity and Duration

( Erika Zemkova ),( Dusan Hamar ) 한국스포츠정책과학원(구 한국스포츠개발원) 2005 International Journal of Applied Sports Sciences Vol.17 No.1

The study examined the effect of fatigue and hyperventilation induced by exercise bouts of different intensity and duration on postural stability. A group of physical education students underwent two exercises on the cycle ergometer, one for abrupt maximal and one for prolonged moderate exercises in different days. One minute prior to and four minutes after the exercises stabilographic parameter (mean velocity of the centre of pressure) was registered at 100 Hz by means of dynamometric platform based on the posturography system FiTRO Sway check. Results showed significantly (p < .01) higher increase in velocity of the centre of pressure immediately after the short-term maximal exercise (from 6.8 to 25.4 mm/s) than after longer exercise of moderate intensity (from 6.9 to 12.4 mm/s). However, during recovery those values resumed back to the baseline more rapidly following short, highly intensive exercise as compared to less intensive longer exercise. It may be concluded that, in early phase of recovery, abrupt maximal exercise has more profound but shorter detrimental effect on parameters of balance than longer exercise of moderate intensity. It appears that such an impairment of postural stability after short-term, high-intensity exercise is mediated mainly by hyperventilation, whereas more pronounced fatigue induced by prolonged exercise of moderate intensity is responsible for longer balance disorders.

이승범(Lee, Seung-Bum),윤성준(Yun, Sung-Jun) 한국웰니스학회 2021 한국웰니스학회지 Vol.16 No.4

본 연구는 50세 이상의 비만중년여성을 대상으로 12주간의 중강도 유산소운동이 비만지표와 뇌 활성도 및 스트레스지수에 미치는 효과를 알아보는데 목적이 있다. 통계방법은 spss 20.0을 이용하였고, 집단 간 비교는 독립 t 검증을 사용하였고, 집단 내 비교는 대응t 검증으로 산출하였다. 12주간 중강도 유산소운동을 실시한 결과 비만지표에서 운동집단이 체중(p<.001), 체지방률(p<.05), 체질량지수(p<.05)가 통계적으로 유의한 감소를 보였다. 12주간 중강도 유산소운동을 실시한 결과 항 스트레스 지수에서 운동집단이 우뇌(p<.05)와 좌뇌(p<.05)에서 통계적으로 유의한 증가를 보였다. 따라서 12주 중강도 유산소 운동은 비만 중년여성에게 비만지표와 스트레스에 긍정적인 영향을 미친다고 판단된다. The purpose of this study was to investigate the effects of 12 weeks of moderate-intensity aerobic exercise on obesity index, brain activity and stress index in obese middle-aged women over 50 years old. As a statistical method, spss 20.0 was used. Independent t-test was used for comparison between groups, and the corresponding t-test was used for comparison within groups. As a result of performing moderate-intensity aerobic exercise for 12 weeks, weight (p<.001), body fat percentage (p<.05), and body mass index (p<.05) of the exercise group showed statistically significant decreases in obesity index. As a result of 12 weeks of moderate-intensity aerobic exercise, the anti-stress index showed a statistically significant increase in the exercise group in the right (p<.05) and left (p<.05) groups. Therefore, it is judged that 12 weeks of moderate-intensity aerobic exercise has a positive effect on obesity index and stress in obese middle-aged women.

가속도계의 손목과 허리착용에 따른 신체활동 예측 타당도

박세정(ParkSaejong),이미현(LeeMihyun) 한국체육학회 2017 한국체육학회지 Vol.56 No.4

최근 가속도계의 손목착용이 편리성이나 수면 중 측정 등의 이유로 허리착용을 대체하고 있으나 아직까지 가속도계의 착용위치에 따른 신체활동 예측의 타당도 논쟁은 계속되고 있다. 본 연구는 ActiGraph GT3X+가속도계의 손목과 허리착용에 따라 예측된 신체활동량과 활동 강도 분류(저·중·고)의 정확도를 비교하고자 한다. 건강한 성인 남·여(19~69세) 54 명을 대상으로 구조화된 일상생활 행위 10가지를 무작위 순서로 실험실에서 수행하게 하였다. 모든 연구대상자는 활동을 수행하는 동안 ActiGraph GT3X+ 가속도계를 손목과 허리에 착용하였으며, 정확도 평가를 위한 준거 신체활동량은 이동식 호흡가스분석기를 사용하여 측정되었다. 연구결과, 가속도계를 허리 착용(허리) 시 준거 신체활동량과 비교하여 과소평가, 손목 착용(손목) 시에는 과대평가하는 것으로 나타났다. 신체활동 강도 분류에서 허리는 고강도, 손목은 중강도 활동에서 준거와 비교하여 가장 높은 오분류를 나타냈다. 또한 중·고강도 신체활동(MVPA)으로 분류하여 비교한 결과, 허리(19.7~20.6%)와 손목(8.1~22.4%)의 활동 강도 오분류 수준이 유사하였다. 결론적으로 ActiGraph GT3X+ 가속도계를 사용하여 신체활동량이나 활동 강도를 저·중·고강도로 세분화하여 해석할 때는 주의가 필요하다. 그러나 신체활동 가이드라인의 MVPA 달성 유무(시간과 빈도)는 허리에서 도출된 분류점을 손목에 활용가능 한 것으로 판단된다. The use of wrist-worn accelerometers to measure physical activity (PA) has been gaining popularity due to compliance and sleep; however, it remains unclear the validity of prediction equations for wrist-worn accelerometers (Wrist-ACC) to measure PA which were originally driven by waist-worn accelerometer (waist-ACC). The purpose of this study was to evaluate the validity of PA measured by waist- vs. wrist-worn ActiGraph GT3X+ accelerometers. Participants of the study (n=54, 19-69 yrs) performed 10 activities of the daily living (ADL) in the laboratory. PA was measured using the Cosmed K4b2 portable system. They also wore the ActiGraph GT3X+ accelerometers on both waist and wrist. As a result of the study, the ADL was underestimated by waist-ACC but overestimated by Wrist-ACC compared to the criterion PA. The misclassification rates were highest in vigorous intensity activities using waist-ACC, but moderate ones for Wrist-ACC. The misclassification rates of moderate-to-vigorous intensity activities (MVPA) ranges from 19.7 to 20.6% for waist-ACC and from 8.1 to 22.4% for Wrist-ACC. In conclusion, researchers should be cautious when subdividing the PA intensities such as light, moderate and vigorous intensities using ActiGraph GT3X+ worn on both waist and wrist. However, MVPA classification rates were similar between waist and wrist-worn ActiGraph GT3X+ accelerometers.
