摘要

目的：比較具運動週期性呼吸者(EPB)與一般肥胖者之間運動生理表現及減重訓練成效是否有差異，並探討減重運動訓練是否能有效改善EPB。研究方法：整理西元2008年1月1日起至2012年12月31日止，曾在台大醫院復健部接受最大運動心肺功能檢查之所有減重班參加者共96名( 24男72女)資料。分析減重前後漸增阻力最大運動測試氣體數據，紀錄所有參加者運動時通氣量起伏最大的3個週期及振幅，根據運動中通氣量起伏情形，將參加者分為具有運動週期呼吸(EPB)組及非EPB組。本研究將(1) 使用相依樣本t檢定，分析運動前後身體組成、心跳血壓及運動氣體分析數據是否有顯著差異(2) 使用獨立樣本t檢定，比較EPB組與非EPB組之間是否有顯著差異(3)比較EPB組減重訓練前後改善情形。結果：96名參加者中，所有參加者經減重運動訓練後通氣量起伏之週期(p<.0001)及振幅/最大通氣量(p=0.0046)都有顯著減少，共15名(8男7女)具有EPB，有6位減重訓練EPB改善，9位參加者仍具有EPB。結論：減重運動訓練可有效降低肥胖者運動時通氣量起伏之週期及振幅，肥胖者EPB改善幅度與身體運動生理參數之相關性，須待進一步研究釐清。

Purpose: To compare exercise physiology performance between obesity with and without EPB and to discuss if weight reduction program can modify the EPB phenomenon in obesity. Method: The Exercise gas analysis data of 96 participants (24 male and 72 female) in National Taiwan University Hospital weight reduction exercise program was collected from 2008/01/01 to 2012/12/31. We recorded the duration and amplitude of 3 maximal fluctuations of ventilation expiration (VE) and divided the participants into two groups (with/without EPB). ). Paired t-tests were used to compare the continuous variables before and after the weight reduction program. Independent t tests were used to compare the difference between EPB and non-EPB group. Wilcoxon two-group tests were used to compare the change of EPB group after the weight reduction program. Result: After the weight reduction program, all participants had significantly reduced VE fluctuation duration (p<.0001) and VE fluctuation amplitude/ VE max (p=0.0046). Amount 96 participants, 15 persons (8 male and 7 female) were defined as EPB. Six of EPB group got improved and 9 of them were still defined as EPB after the weight reduction exercise program. Conclusion: The weight reduction exercise program can significant reduce the duration and amplitude of VE fluctuation. The correlation between the improvement of EBP and other exercise physical index need further studies to investigate.
