흡연자의 단시간의 흡연 중단이 안정 시 및 저강도(40% of $VO_2max$), 중강도(60% of $VO_2max$)에서의 일회성 유산소성 운동 중에 나타내는 심혈관 반응의 차이를 알아보는데 있다. 따라서 성인 남성 흡연자를 대상으로 흡연 직후, 흡연 중단 24시간과 흡연 중단 48시간 경과 후의 안정 시, 저강도, 중강도의 강도별 사이클 에르고미터를 통한 일회성 유산소 운동 시 심혈관계 반응을 검토하였다. 이에 따른 결과 흡연 직후, 흡연 중단 24시간과 흡연 중단 48시간 경과 후의 안정 시, 저강도, 중강도의 수준의 운동 강도별 사이클 에르고미터를 통한 일회성 유산소 운동 시 SBP, DBP, MAP, HR에서 유의한 감소가 나타났다($p$<0.05). 또한, 안정 시와 중강도에서는 CO의 유의한 감소가 나타났다($p$<0.05). 이상의 결과로부터 단시간의 흡연 중단은 교감신경의 항진상태를 완화시키고, 부교감신경계의 활성화로 인해 HR을 감소시킴으로써 안정 시와 동일 강도 유산소운동 시의 과도한 심혈관 반응을 완화키는 것으로 사료된다. 이를 통해 흡연자에게 있어 단기간의 흡연 금지만으로도 운동 중에 심혈관계 반응의 위험을 감소시킬 수 있다는 가능성을 나타냈다.

PURPOSE: This study examined the influence of treadmill exercise with initial pain control using transcutaneous electrical nerve stimulation (TENS) on induced pain of knee osteoarthritis in rats. METHODS: Thirty adult male Sprague - Dawley rats were divided randomly into the TENS Group (TG, n = 10), Treadmill Exercise Group (TEG, n = 10), and Treadmill with TENS Group (TTG, n = 10). In the TG, TENS was performed for 20 min per day for two weeks with a TENS program at the knee joint. The TEG performed treadmill exercise 15 m/min for 20 min per day for two weeks. The TTG performed initial pain control by TENS program during the 1st ~ 3rd days, and treadmill exercise was performed using the TEG methods from the 4th day. The lumbar spine was extracted and processed using western blot analysis to evaluate pain (c-fos expression). RESULTS: The results showed that c-fos expression was decreased significantly in all groups after each intervention (p < .05). In particular, TTG produced the most significant decrease compared to the other groups. CONCLUSION: These results suggest that treadmill exercise with initial pain control using TENS is a suitable method for relieving pain in knee osteoarthritis.

The purpose of this study is to develop and evaluate the Self Efficacy Promotion and Exercise Training Program to decrease anxiety and depression and to increase the quality of life for kidney transplant recipients. The subjects were selected randomly among the patients who underwent renal transplant at three major transplantation hospitals in Seoul, Korea. The observed subjects in this study consisted of 56 patients who had renal transplantations between one to twelve months prior to this study. The patients did not take any regular physical exercise. This study was carried out between November, 1999 and March, 2000. The study groups were divided into 3 groups; exercise training group (n=16), self efficacy group (n=18) and control group (n=22). The exercise training group received self efficacy promotion and exercise training program for 12 weeks. The self efficacy group received self efficacy promotion education, but no exercise training was given. The control group was not offered any education. The anxiety, depression and quality of life were evaluated 3 times, before the experiment, after 8 weeks and after 12 weeks. The data were analyzed with mean, standard deviation, Chi-square test, ANOVA and $Scheff\acute{e}$ test. The results were as follows: 1. After the experiment, anxiety and depression scores of the exercise training group and self efficacy group were more significantly decreased than those of the control group (p=.05). 2. After the experiment, the quality of life score of the exercise training group and self efficacy group were more significantly increased than those of the control group (p=.05). This study showed that the Self Efficacy and Exercise Training Programs were effective. Therefore, it is expected that the Self Efficacy Promotion and Exercise Training Program could be widely applied as an effective independent nursing intervention to decrease anxiety and depression and to increase quality of life for kidney transplant recipients.

The purpose of this study was to identify the effect of cerebral ischemia on affected(Lt) and unaffected(Rt) side of soleus, plantaris and gastrocnemius muscle mass and determine the effect of exercise on affected and unaffected side on soleus, plantaris and gastrocnemius muscle mass during acute stage of stroke. Sixteen male Sprague-Dawley rate with 200-270g body weight were randomly divided into three groups: control, stroke, and exercise after stroke(St+Ex) group. The control group received sham operation and the stroke group and St+Ex group received transient right MCA(middle cerebral artery) occlusion operation. The St+Ex groups ran on a treadmill for 20min/day at 10m/min and $10^{\circ}$ grade for 6days. During the experimental period body weight and diet intake was measured every morning. On the 7th day after operation, muscles were dissected from both affected and unaffected side of hindlimb. Cerebral infarction of stroke and St+Ex groups were identified by staining with TCC for 30 minutes. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Significance was accepted at the level of p<0.05. The results were summarized follows : 1) There were no significant difference of the body weight on the first day of experiment among 3 groups. Whereas on the 7th day, the body weight of both stroke group and St+Ex group were significantly smaller than that of control group. Body weight of St+Ex group on the 7th day tended to be larger than that of stroke group. 2) Total diet intake of both stroke group and St+Ex group were also significantly smaller than that of control group. While total amount of diet intake in St+Ex group tended to be larger than that of stroke group. 3) The weight of gastrocnemius muscle of affected side in stroke group significantly decreased compared to that of control group and the weight of soleus and plantaris muscle of affected side in stroke group tended to decrease compared to that of control group. 4) The weight of plantaris muscle of unaffected side in stroke group significantly decreased compared to that of control group and the weight of soleus and gastrocnemius muscle of unaffected side in stroke group tended to decrease compared to those of control group. 5) The weight of gastrocnemius muscle of affected side in stroke group significantly decreased compared to that of unaffected side and there was no significant difference of the weight of soleus and plantaris muscle in stroke group between affected side and unaffected side. 6) The weight of soleus, plantaris and gastrocnemius muscle of both affected side and unaffected side in St+Ex group had a tendency of increase compared to those of stroke group. The relative weight of soleus and gastrocnemius muscle of affected side and soleus muscle of unaffected side in St+Ex group had a tendency to increase compared to those of stroke group. Based on these results, exercise during acute stage of stroke might attenuate muscle atrophy of both affected and unaffected side of hindlimb muscles.

PURPOSE: The main objective of this study is observing the effects of the functional postural trunk exercise (FPTE) on deep cranio-cervical flexor (CCF) muscle endurance applied on neck pain patients suffering from the acute whiplash-association disorder (WAD). METHODS: The study was tested with 47 patients with neck pain. All patients were equally treated with the ordinary therapy, only experimental group (n=23) was treated with FPTE: assumption of an upright lumbo-pelvic and spinal postural position, adding a neck lengthening manoeuvre in addition. Patients attended physical therapy for 3 times a week, for 4 weeks. Visual analogue scale (VAS) for pain, neck disability index (NDI), range of motion (ROM), were recorded both before and after the intervention. Also muscle activity in the CCF test was employed to analyze the changes between before and after. RESULT: After 4 weeks of training intervention, a remarkable increase in muscle endurance, rotation, extension ROM (p<.05) and decrease in pain and NDI (p<.05) in both groups. Further, the differences between groups were muscle endurance (F=60.350, p<.01), pain, and the left rotation ROM (p<.05). CONCLUSION: From the results, the experimental group had significant the increase in muscle endurance, and the significant decrease in pain. Whilst further research in this category is necessary, these observations suggest that applying exercise in early diagnosis can be of help to treat the neck pain patients suffering from the WAD.

Background: The purpose of this study was to systematic review the effect of exercise programs for chronic low back pain patients. We needs systematic development of low back pain exercise program to reduce economic cost further doing great service to public health promotion. Methods: We searched to the effects of exercise programs for chronic low back pain patients by Dankook University electronic library databases of DBPIA, KSI KISS, CINAHL, MEDLINE and PEDro combined with a hand search of papers published in relevant journals. Any type of study relevant to the topic published during time period from 1970 to 2007 was included. Results: The literature search identified 30 studies. 1.Performing the flexion exercise increased abdominal muscle activity but acute herniated intervertebral disc should be avoided. 2.The general lumbar extension exercise used lumbar extension machine and the muscle power increases, significant probability the change. 3.The spinal segments exercise for the patients offered significant efficacy and appeared to be a reasonable therapeutic option. 4.Spinal stabilization exercises appear to improve trunk endurance and balance to patients with chronic low back pain. This exercise programs had effective decrease pain and disability. Conclusion: The review suggests that although the exercise programs for chronic low back pain patients, and we expected the efficacy of the exercise programs for chronic low back pain patients used in this study should be further investigated in a long period study and objective outcomes.

PURPOSE: The aim of this study was to review the effects of exercise intervention on blood glucose control in obese type 2 diabetic patients. METHODS: The PubMed and KERISS search engines were used and 61 papers that met the key questions were selected. RESULTS: Exercise is an effective intervention for the control of blood glucose in type 2 diabetic patients because it does not impair glucose transport in the skeletal muscle induced by muscle contractions. Insulin resistance, which is characteristic of type 2 diabetes, is caused by decreased insulin sensitivity or insulin responsiveness. Acute exercise improves the glucose metabolism by increasing the insulin-independent signaling pathways and insulin sensitivity in the skeletal muscle, and regular long-term exercise improves the skeletal muscle insulin responsiveness and systemic glucose metabolism by increasing the mitochondrial and GLUT4 protein expression in the skeletal muscle. CONCLUSION: The improvement of the glucose metabolism through exercise shows a dose-response pattern, and if exercise consumes the same number of calories, high intensity exercise will be more effective for the glucose metabolism. On the other hand, it is practically difficult for a patient with obese type 2 diabetes to control their blood glucose with high intensity or long-term exercise. Therefore, it will be necessary to study safe adjuvants (cinnamic acid, lithium) that can produce similar effects to high-intensity and high-volume exercises in low-intensity and low-volume exercises.

[Purpose] This study was performed to investigate the acid-base and ion balance at rest and after exercise in healthy males under normoxia, moderate hypoxia, and severe hypoxia. [Methods] Ten healthy Korean males completed three different trials on different days, comprising exercise under normoxia (F_iO₂ = 20.9%, N trial), moderate hypoxia (F_iO₂ = 16.5%, MH trial), and severe hypoxia (F_iO₂ = 12.8%, SH trial). They undertook endurance exercise for 30 min on a cycle ergometer at the same relative exercise intensity equivalent to 80% maximal heart rate under all conditions. Capillary blood samples were obtained to determine acid-base and ion balance at rest and after exercise. [Results] Exercise-induced blood lactate elevations were significantly increased as hypoxic conditions became more severe; SH > MH > N trials (P = 0.003). After exercise, blood glucose levels were significantly higher in the SH trial than in the N and MH trials (P = 0.001). Capillary oxygen saturation (S_CO₂) levels were significantly lowered as hypoxic conditions became more severe; SH > MH > N trials (P < 0.001). The pH levels were significantly lower in the MH trial than that in the N trial (P = 0.010). Moreover, H_CO_3^- levels were significantly lower in the SH trial than in the N trial, with significant interaction (P = 0.003). There were no significant differences in blood Na⁺, K⁺, and Ca²⁺ levels between the trials. [Conclusion] MH and SH trials induced greater differences in glucose, lactate, S_CO₂, pH, and HCO_3^- levels in capillary blood compared to the N trial. Additionally, lactate, S_CO₂, and HCO_3^- levels showed greater changes in the SH trial than in the MH trial. However, there were no significant differences in Na⁺, K⁺, and Ca²⁺ levels in MH and SH trials compared to the N trial.

Objectives To evaluate the clinical utility of MET performed on sternocleidomastoid muscle of acute nuchal pain patients, we measured a change of meridian electromyography. Methods We compared electrical activity before and after MET performed on sternocleidomastoid muscle of acute nuchal pain patients in same group (n=20) in isometric exercise state during five seconds. We analyzed amplitudes and areas of electrical activity and asymmetry index (AI). Results 1. After MET performed on sternocleidomastoid muscle of acute nuchal pain patients, maximum voluntary isomeric contraction (MVIC) was significantly increased more than before MET performed (p<0.005). 2. Comparing with before MET performed on sternocleidomastoid muscle of acute nuchal pain patients, muscle fatigue after MET performed on sternocleidomastoid muscle of acute nuchal pain patients decreased but there was no significant difference. 3. Comparing with before MET performed on sternocleidomastoid muscle of acute nuchal pain patients, asymmetry index (AI) after MET performed on sternocleidomastoid muscle of acute nuchal pain patients decreased but there was no significant difference. Conclusions According to above results, after performing MET on sternocleidomastoid muscle of acute nuchal pain patients, maximum voluntary isomeric contraction (MVIC) increased significantly, so it is certain that performing MET on sternocleidomastoid muscle has a clinical effect.
