The purpose of this study was to investigate effect of resistance training on BMD and bone metabolism related markers in aging rats. Thirty male Spraugue-Daweley rats were divided into sedentary (CON; n=10 ) non-load resistance trained(NLRTG; n=10), and load resistance trained(LRTG; n=10) groups at the age of 64 weeks. The rats in the resistance training groups((NLRTG and LRTG) performed the tower climbing exercise 4 times a week. The LRTG groups were conditioned to climb a vertical ladder with weights appended to their tail 4 days/wk for 12 wks. After 12 weeks of exercise, serum osteocalcin, bone mineral density (BMD), breaking force, ash, Ca, and P in the femur were measured. After training, serum osteocalcin (OC) was significantly (p < 0.05) higher in both LRTG and NLRTG when compared to Control. Right femur BMD was significantly (p < 0.05) greater for LRTG when compared to both NLRTG and Control with no significant difference between NLRTG and Conrtol. The breaking force of femur was significantly (p < 0.05) greater for LRTG and NLRTG when compared to Control. The Ash, Ca, content of femur were significantly increased in resistance training groups than control group. These results suggest that the increase in bone mineral density induced by resistance training is mediated by changes in bone microarchitecture as well as training intensity and osteocalcin.

본 연구는 2008년 1월부터 2008년 12월까지 S 유치원 원아40명(실험군 20명, 대조군 20명)의 뇌파를 검사하여 뉴로피드백 훈련 전과 훈련 후의 스트레스 저항 능력을 보고자 하였다. 훈련 전과 후의 스트레스 저항 능력은 시계열 선형분석을 통하여 비교하였으며, 연구의 결과로 뉴로피드백 훈련을 적용한 집단에서 항 스트레스 지수에서 유의미한 차이를 보였다. 이 결과는 뉴로피드백 훈련이 유아들의 스트레스 저항 능력을 높여 주었으며 정서적 성향에 긍정적인 영향을 미쳤다고 본다.

본 연구는 2008년 7월부터 2008년 12월까지 I시 P뇌훈련센타에 정서적 성향이나 학습능력 향상을 위하여 방문한 내담자 48명(실험군 24명, 대조군 24명)의 뇌파를 검사하여 뇌파 조절 훈련 전과 훈련 후의 스트레스저항능력의 변화와 스트레스저항능력이 학업성취도에 미치는 영향을 보고자 하였다. 훈련 전과 후의 스트레스저항능력의 비교는 뇌기능 분석을 통하여 비교하였으며, 학업성취도의 변화를 보기 위하여 5점 척도 설문지를 이용하였다. 연구의 결과로 뇌파 조절 훈련을 적용한 실험군에서 항스트레스지수와 학업성취도에서 유의미한 차이를 보였다. 이는 뇌파 조절 훈련이 초등학생들의 스트레스저항능력을 높여 주었으며 이결과가 학업성취도에 긍정적인 영향을 미쳤다고 본다. 따라서 본 연구 결과는 뇌기능 변화가 학생들의 육체적, 정신적 스트레스나 저항능력 등의 객관적 지표로서 활용될 수 있는 가능성을 제시한 점에서 의의가 있으며, 이에 대한 경험적 증거의 축적을 위한 후속연구가 필요하다고 본다.

This study was to examine the effectiveness of brainwave training by observing the pre and post brainwave measurement results of about 48 (experimental group 24, comparative group24) subjects who have shown resistancestress and student assessment. The study took place at neuro-training center in P city I, during Jul. 2008 and Dec. 2008. As the brainwaves are adjusted by Brain Quotient, the tool used to measure the student assessment was 5Likert Scale questionnaire. The result confirmed the differences of both resistance stress quotient and student assessment. The result of the study suggest brainwave technique's possibility in positively affecting the subjects" resistance stress quotient and student assessment. This study revealed meaningful relation between neurofeedback training and stress among several categoties, while suggesting follow-up researches figuring out more detailed explanations.

연구목적: 본 연구는 만성 뇌졸중 환자를 대상으로 흡기근 저항훈련이 횡격막 두께와 폐기능 및 흉곽 확장에 미치는 효과를 알아보고자 수행하였다. 연구방법: 연구 대상자는 총 29명(남자 17명, 여자 12명)으로 흡기근 저항훈련군(15명)과 대조군(14명)으로 분류하였다. 모든 대상자는 6개월 이상된 만성 뇌졸중 환자로 일반적인 신경발달치료를 받고 있으며, 같은 기간 동안 흡기근 저항훈련군에 역치부하 흡기근육 단련기(threshold IMT device)를 제공하고 주 3회${\times}$1회 20분씩 6주간 시행하였다. 마비측과 비마비측 횡격막 두께측정을 위해 초음파의 7.5MHz linear probe를 사용하여 최대 흡기시(Tdi.con)와 휴식시(Tdi.rel)의 두께를 측정하고 수축률(TR)을 계산하였다. 또한 폐 활량계를 사용하여 노력성 폐활량을 측정하였으며, 줄자를 사용하여 흉곽 확장을 측정하였다. 연구결과: 6주간 중재 후 흡기근 저항훈련군에서 최대흡기시 횡격막 두께(Tdi.con)와 수축률(TR)은 유의한 증가를 보였다(p<.05). 1초간 노력성 호기량 ($FEV_1$)과 최대 호기 속도(PEF)도 유의한 증가를 보였으나(p<.05), 노력성 폐활량(FVC)과 1초간 노력성 호기량의 노력성 폐활량에 대한 비($FEV_1$/FVC), 흉곽 확장은 유의한 증가는 보이지 않았다(p>.05). 결론: 본 연구는 만성뇌졸중 환자를 대상으로 흡기근 저항훈련의 적용이 횡격막의 수축력과 폐기능 및 흉곽 확장력을 향상시켜 호흡근의 협응력을 증가시키고, 비활동성으로 인해 감소된 운동내성을 증가하게 함으로써 향후 재활에서 만성 뇌졸중 환자에게 2차적인 기능향상에 도움을 줄수 있을 것으로 보여진다.

This study was to examine the effectiveness of neurofeedback training by observing the pre and post brainwave measurement results of about 16(Primary Student 6, middle school student10) student who have shown resistance stress and body stress, mental stress. The study was examined at S city M dong A hearing impairments student, from Mar. 2008 and to Feb. 2009. The methodology used in the study is the Coloring Analysis Program of the Brain Quotient Test. As the brain waves are adjusted by timeseries linear analysis, the brain function quotients can reflect the functional states of the brain. The training took place two times a week, for about 40 minutes per session. The result confirmed the differences of both resistance stress quotient and body stress, mental stress. The results of the analysis show that neurofeedback training plays positive role in changing the brain function. Therefore, the result of the study shows that there is possibility that Neuro Feedback technique might be positively affecting resistance stress of the hearing impairments student, relationship between neurofeedback training and stress among several categories.

This study was performed to observe the responses of angiogenesis-related protein expression in skeletal muscle of aged rats by regular resistance exercise training with aerobic exercise. For the purpose of the study, naturally aged SD rats (20-24 months, N=18) were used and divided into control (CON, n=6), resistance exercise (RE, n=6), and resistance + aerobic exercise (RE + AE, n=6) groups. RE group performed 3 sets × 4 exercises each session using a ladder for laboratory animals, and RE +AE group performed 2 sets × 3 times of ladder climbing and additional treadmill running (30 min) each session. After 8 weeks of exercise training, soleus muscle and extensor digitorum longus muscle (EDL) were extracted and used for analysis. Western blot was performed to analyze the expression levels of angiogenesis-related proteins (HIF-1α, VEGF, FLK-1, Ang-1, Ang-2) in skeletal muscle. As a result of the study, the expression of HIF-1α, VEGF, FLK-1, Ang-1, and Ang-2 proteins in soleus muscle (type I muscle) was higher in RE +AE than in CON group, and HIF-1α, VEGF, Ang-1, Ang-2 protein expression of RE group was higher than that of CON group. Furthermore, Ang-2 to Ang-1 ratio of RE + AE group was higher than that of RE group, showing differences by exercise type. In EDL muscle (type II muscle), HIF-1α was increased only by RE group, whereas VEGF and FLK-1 protein expressions were increased in both training types, and no difference was observed between the types of exercise training. In addition, there was no difference in angiopoieitin protein expressions in EDL muscle by exercise training. Therefore, in aging, regular exercise training induces skeletal muscle angiogenic response regardless of exercise type, and in particular, the combination of aerobic exercise with resistance exercise may have an additional positive effect on angiogenesis in type I muscle.

The purpose of this study was to evaluate the effect of the tongue's maximum resistance training program on the accuracy of the tongue training program using the Iowa Oral Performance Instrument (IOPI) and to compare the effects of tongue muscle strength and spoken language function on objective function. The experiment was diagnosed with stroke hemiplegia divided into tongue pressure strength and accuracy training therapy group and the oromotor exercise therapy group Anterior Tongue Pressure(ATP), Posterior Tongue Pressure (PTP), and Posterior Tongue Pressure (PTP) were measured before and after the intervention to evaluate changes in tongue strength and verbal ability. Maximum Phonation Time (MPT). The results of this study are as follows. There was no significant difference in tongue strength and verbal function between training group and oral facial exercise group. There was no significant difference between tongue strength training and oral facial exercise group. Therefore, it was shown that the tongue pressure strength and accuracy training therapy group was not effective to improve tongue muscle strength and spoken language ability than the oromotor exercise therapy group.
