본 연구에서는 20대 여성의 카페인 중독이 심장호흡기계 능력에 미치는 영향을 조사하였다. 본 연구의 대상자는 G 광역시 소재의 H 대학교 여학생 35명을 카페인 중독자(n=17)과 카페인 비중독자(n=18)가 참여하였다. 심장능력을 평가하기 위해 사이클 에르고미터를 사용하여 최대산소섭취량, 최대에너지소비량, METs를 측정하였으며, 호흡기계 능력은 파워브리드 K5를 사용하여 최대들숨압, 평균들숨압, 최대들숨유속, 평균들숨유속, 최대들숨량, 평균들숨량을 측정하였다. 본 연구의 결과는 심장능력에서 카페인 중독군은 카페인 비중독군에 비해 최대산소섭취량과 METs에서 통계학적으로 유의한 감소를 보였으며, 호흡기계 능력에서는 카페인 중독군이 비중독군에 비해 최대들숨압, 평균들숨압, 최대들숨유속, 평균들숨유속에서 통계학적으로 유의한 감소를 보였다. 본 연구의 결과를 종합하면, 카페인 중독은 20대 여성의 심장호흡기계 능력의 감소를 보였다. 따라서 본 연구의 결과는 20대 여성의 카페인 중독예방을 위한 기초자료로 활용할 수 있을 것이다.

Objective: The purpose of this study is to prove the reliability and validity of the Power breath K5 and to compare it with pony FX. Power breathe K5 is one type of device can assess automatically Maximum inspiratory pressure (MIP), Peak inspiratory pressure, Peak inspiratory flow (PIF). Design: Cross-sectional study. Methods: Thirty-five COPD patients participated in the test to investigate for the intra relater reliability and concurrent validity. The tests MIP, Vital capacity (VC), PIF were measured by Powerbreathe K5 and Pony Fx. Data was analyzed by intraclass correlation reliability (ICC) value and a standard error of measurement and Bland-Altman plots for reliability and pearson correlation for validity. Results: Intra rater reliability of the Powerbreathe K5 was very high at MIP (ICC=0.977 95%CI 0.956~0.989, SEM=8.665, MDC=0.295), PIF (ICC=0.966 95%CI 0.933~0.93, SEM=8.665, MDC=0.295), VC (ICC=0.949 95CI 0.902~0.974, SEM=0.042, MDC=0.116). The Powerbreath K5 was significant correlation compared with Pony Fx in assessment for MIP (r=0.971, p<0.05) and vital capacity (r=0.534, p<0.05). Conclusion: In this study, We investigated the clinical usefulness of the Powerbreath K5 in evaulating the MIP, VC and PIF with COPD patients with high reliability and validity.

Purpose: The purpose of this study was to classify patients with chronic back pain according to the degree of their back pain, and to compare the pain dysfunction index with the qualitative changes in abdominal muscles. Therefore, we aimed to provide a basis for the treatment intervention method for patients with back pain. Methods: Twenty patients with chronic back pain were purposive sample to a group of 10 patients with a back pain index of 60 % or more and a group with less than 60 % of back pain, and the subjects who voluntarily participated in the study After receiving the letter, I conducted the research the dysfunction of back pain was measured by the Korean version of the Oswestry Disability Index (KODI), and the ultrasonic wave (Ultrasound MyLabOne, ESAOTE, Italy) And the white area index, and the abdominal muscle movement was used as the exercise instrument POWER breathe K5 (Hab direct, UK), which strengthens the respiratory muscles through threshold-muscle traction. Result: In this study, patients with chronic back pain were subjected to breathing exercises, which led to the decrease in back pain dysfunction. The ultrasonographic analysis of abdominal muscles revealed that both the white area index and muscle image density in the skeletal muscle and in the outer muscle of the abdomen gradually decreased over time. Conclusion: It is thought that introducing back pain patients to abdominal muscle reinforcement training is effective in improving the functions of the patients' muscles, thus increasing their quality of life.

Background: To evaluate the effect of thoracic mobility exercise and deep breathing exercise applied to stroke patients on pulmonary function. Methods: The subjects were divided into two group. Twenty-five patients with stroke were randomly assigned to DB (deep breathing exercise) group (n=13) and TM (combination of deep breathing exercise and thoracic mobility exercise) group (n=12). During four weeks, DB group were carried out deep breathing exercises for 5~10 minutes twice a day and TM Group were carried out deep breathing exercises for 5~10 minutes and thoracic mobility exercise for 20~30 minutes twice a day. All tests were completed before and after experiment. The pulmonary functions were measured by PowerBreathe K5 (Hab International Ltd, England) and tape measure respectively. For each case, the experimental data were obtained in 4 items; average of inspiratory load, inspiratory flow speed, inspiratory flow volume and chest expansion. Results: The results of this study were as follows: 1. In DB group, the statistically significants were shown on average of inspiratory flow speed, inspiratory flow volume and chest expansion (p<.05). 2. In TM group, the statistically significants were shown on all items (p<.05). 3. There was a statistically significant difference on all items between DB group and TM group (p<.05). Conclusions: The above results revealed that DB and TM group can be used to improve pulmonary function in stroke patients. In comparison of DB and TM group, TM group was more improved. In conclude, thoracic mobility exercise helped improving function of vital capacity and chest expansion in stroke patients.
