최근 다양한 연구를 통하여 전신 진동기 운동이 신체의 근골격계, 순환계 및 내분비계 등에 효과적임이 보고되고 있다. 특히 전신 진동운동이 노인의 낙상예방, 파킨슨 및 뇌졸중 환자와 같은 신경학적 질환자의 자세조절 및 기능향상을 위한 재활치료 방법으로 효과가 있다고 밝혀졌다. 그러나 아직까지 전신 진동운동에 적합한 의료 허가를 받은 제품이 없으며, 일부 유사한 진동감을 제공하는 기기를 위주로 제작되고 있는 상황이다. 추후 의료기기의 수요를 고려할 때 고령사회로의 진입 속도가 빨라짐에 따라 노인들에게 적합한 진동기의 개발이 필요하다. 노인들은 운동참여에 보수적이며 사회성이 떨어지기 때문에 운동기의 기능적 요건과 더불어 참여를 유도하는 환경 요인을 함께 제공할 필요가 있다. 본 논문에서는 진동 운동기를 이용한 운동 효과를 분석하고 전신 진동운동에 적합한 가상현실 컨텐츠를 제시하였으며, 국내외 개발 및 연구 중인 기기와 컨텐츠 개발 동향을 제시하였다.

The Mechanisms of whole body vibration on the human body is not clearly presented despite of the research result and there is not enough research that shows the effects of vibration on the kinetic changes of the lower joint. Therefore, this study focuses on finding out which lower joint is related with kinetic vertical jump ability. Five male and five female who didn't have orthopedic history were selected as the subjects. The subjects carried out three squat jumps before and after 5minutes of 30Hz whole body vibration. We have utilized a 3D motion analysis system to analyze the kinetic changes of the lower joint in the vertical jump. The height of subjects squat jump was improved after whole body vibration treatment. Also, the lower joint moment and power increased. However, there were no statistically significant changes in GRF, hip joint moment and power after the whole body vibration proved to have positive effect on the ankle and knee joints but showed negative effect on the hip joint.

The purpose of this study was to examine the effects of whole-body vibration exercise for life care on balance and walking ability in the fall risk stroke patients. 30 stroke patients were divided into two groups, Otago exercise group(n=15) and whole-body vibration exercise group(n=15). Walking ability were measured by 10m walking and Tinetti mobility test with stroke patients and balance ability were measured by BBS and TUG on comparative analysis of pre, post exercise. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that BBS and Tinetti mobility test of the both groups were increased statistically significantly and TUG and 10m walking test of the both groups were decreased statistically significantly. balance ability and walking ability of the whole-body vibration exercise group were improved statistically significantly in comparison with those of the Otago exercise group. The results of this study showed that whole-body vibration exercise for the improvement of life care had significant effects on improving BBS, TUG, 10m walking and Tinetti mobility test of fall risk stroke patients. Therefore, it is recommended to apply whole-body vibration exercise to improve life-care through improving balance ability and walking ability of fall risk stroke patients.

The purpose of this study is to clarify the effects of whole-body vibration and to provide scientific basis for effective exercise by analyzing the differences in lower extremity muscle activation according to squat position during whole body vibration. In this study, muscle activation during whole-body vibration was measured in 10 healthy males in their 20s with no orthopedic conditions during standing posture, deep squat, half squat, and heel raise squat. Muscle activation was compared by measuring the root mean square (RMS) with electromyography electrodes attached to lateral gastrocnemius, tibialis anterior, vastus lateralis, and biceps femoris. The vibration intensity was applied in combinations of the volumes of 50 and 80 and the frequencies of 10, 25, and 40 Hz in each posture. The results showed that there were differences in muscle activations of external gastrocnemius, tibialis anterior, and vastus lateralis among the position(p<.05). The heal raise squat was found to have a high muscle activation effect.

This research was to investigate the effect of fatigue reduction and heart rate recovery (HRR) according to whole body vibration (WBV). 20 healthy participants were recruited and divided into vibration group (VG) and none vibration group (NVG). VG was group with provided vibration and NVG was group without vibration. They exercised slope gait with 8.5 degree and 4km/h during 30min. They rested on the chair type vibrator during 30min. The vibration consists of 10hz as frequency and 5mm as amplitude. We measured the lactate in the blood and HRR before, immediately after exercise and after rest session. The results showed that lactate level in VG the more decreased at 95.2%. The result of HRR was similar including recovery at 50.67% in VG. The WBV with stimulated vessel in muscle assisted the recovery function by reducing the excess post-exercise oxygen consumption (EPOC) quickly and improving blood circulation. The rest with WBV could provide efficient cool-down exercise for elderly and women without other physical activities after exercise.

The purpose of this study is to investigate muscle function and symmetry index during whole body vibration exercise using lower extremity training posture for throwing athletes. For throwing athletes in their 20s(6 males, 4 females, age: 24.60±0.92years, height: 177.90±7.40cm, weight: 92.90±22.97kg), lower extremity training postures with squat, carphrase, and lunge movements. Whole body vibration exercise training was performed using. Tensiomyography(TMG) variables Time Delay(Td), Time Contraction(Tc), Time Sustain(Ts) Time Relaxation(Tr), and Displacement Maximumal(Dm) in the lower extremity joint muscles(biceps femoris(BF), gastrocnemius lateral(GL), gastrocnemius medial(GM), rectus femoris(RF), tibialis anterior(TA), lateral vastus(LV), medial latissimus(ML)), were measured to compare and analyze muscle activity, muscle fatigue, and left-right symmetry. The results of the study are left RF, VL, right VM (p<.05) in Td, VM (p<.05) in Tc, GM in Ts (p<.05), left RF in Tr, and right TA (p<. 05) showed a change. Therefore, it has been proven that various whole-body vibration training is an effective exercise with changes in muscle contraction, and stability of the core is secured by symmetry of the left and right muscles. For this reason, the whole body vibration exercise will have a positive effect on rehabilitation training, and it is believed that it will be able to improve performance.

Background : The effects of chemotherapy on pulmonary function are mainly a reduced diffusion capacity and a restrictive ventilatory impairment. Exercise can expose cardiovascular and pulmonary abnormalities not evident at rest. Exercise related cardiopulmonary function is important in patients with malignant disease as a determinant of quality of life. We performed this study to evaluate the changes of body composition and cadiopulmonary exercise perfoemance of patients with locally advanced, non-small cell, lung cancer (NSCLC) before and after chemotherapy. Methods : We evaluated resting pulmonary function, body composition, physiologic performance status, and cardiopulmonary exercise function in 11 patients with locally advanced NSCLC, at diagnosis and prior to the fourth cycle of chemotherapy. Results : After chemotherapy, 4 patients (36.4%) showed partial response and 7 (63.4%) had stable disease. After chemotherapy, diffusion capacity of the lung for carbon monoxide was reduced ($89.7{\pm}34.1%$, vs. $71.9{\pm}20.5%$) but not significantly. There were no significant changes in body composition or the state of physiologic performance after chemotherapy. There was a significant impairment of cardiopulmonary exercise tolerance in patients with NSCLC, evidenced by a reduction of maximal oxygen uptake ($VO_2$max, ml/kg/min, $17.9{\pm}2.6$ : $12.6{\pm}6.1$, <0.05) and $O_2$pulse ($O_2$ pulse, ml/beat, $7.0{\pm}1.7$, $5.2{\pm}2.1$, <0.05). Conclusion : Systemic chemotherapy resulted in a loss of cardiopulmonary exercise function in patients with locally advanced NSCLC within the short-term period, but not a physiologic change of body composition within the same period.

에어로빅은 전신 지구력이 요구되는 운동으로 유산소 운동의 대표적인 운동이라 할 수 있다. 에어로빅(Aerobic)이란 말은 '살아 있는 공기를 마시며(living in air)', '산소를 이용하여(utilizing oxygen)', '산소와 함께(With oxygen)'란 뜻의 용어에서 출발했다. 단어에서 볼 수 있듯이 에어로빅 산소공급운동을 뜻하며 몸 안에 최대한 많은 양의 산소를 공급하여 폐와 심장의 기능을 촉진해주는 운동을 말한다.
