Repeated sessions of exercise burn more fat than a single, long session. 会议反复运动烧脂肪较单一，长会议。

The American Physiological Society - Taking a break in the middle of your workout may metabolize more fat than exercising without stopping, according to a recent study in Japan.  Researchers conducted the first known study to compare these two exercise methods - exercising continually in one long bout versus breaking up the same workout with a rest period.  The findings could change the way we approach exercise.  Who wouldn’t want to take a breather for that?美国生理社会-休整的中，你可以锻炼更多的代谢脂肪比行使而不停车，根据最近的研究在日本。研究者进行了一次名为研究，以比较这两个演习的方法-运动不断在一长布特相对于分手同一锻炼与休息。结果可能改变我们的方式行使。谁不想以喘息为何？

“Many people believe prolonged exercise will be optimal in order to reduce body fat, but our study has shown that repetitions of shorter exercise may cause enhancements of fat mobilization and utilization during and after the exercise. "许多人相信长时间运动将优化，以减少体内脂肪，但我们的研究显示，重复短演习可能引起增强脂肪动员和利用期间和之后演习。 These findings will be informative about the design of [future] exercise regimens,” said lead researcher Kazushige Goto, Ph.D.这些结果将左右翔实设计[未来]运动疗法，说： "研究员带领千叶藤博士 “Most people are reluctant to perform a single bout of prolonged exercise. "大多数人都不愿意履行单一一番长时间运动。 The repeated exercise with shorter bouts of exercise will be a great help [in keeping up with fitness].”反复演练较短多次演习将有很大的帮助[跟上健身] 。 "

This finding is part of a study entitled “Enhancement of fat metabolism by repeated bouts of moderate endurance exercise”, found in the June 2007 edition of the Journal of Applied Physiology , which is published by the American Physiological Society.这一发现是一个研究报告，题为"加强脂肪代谢反复多次温和耐力运动" ，发现在2007年6月杂志应用生理学 ，即出版，由美国生理社会。

Summary of Methodology 简易方法

The researchers used seven healthy (avg. body mass: 66.1, percentage fat: 17.6) men with an average age of 25 who were physically active and familiar with exercise and had them perform three separate trials:研究人员用七个健康（ avg.体重： 66.1 ，脂肪百分比： 17.6 ） ，与男性的平均年龄为25名肢体主动和熟悉工作，并履行他们三个独立审判：

1) one single bout of 60-min exercise followed with a 60-min recovery period (Single) 1 ）单一布特60分钟后，演习与60敏回收期（单人）
2) two bouts of 30-min exercise with a 20-min rest after the first 30-min bout, along with a 60-min recovery period at the end (Repeated) 2 ）两种货币30分钟运动20分钟休息后，首30分钟布特，随着60敏复苏期在年底（重复）

3) one 60-min rest period (Control) 3 ）一个60分钟的休息时间（管制）

The men performed each trial at the same time of day after fasting overnight.  They exercised on a single ergometer (cycling machine) at the commonly recommended exercise prescription of 60% maximum oxygen intake.  The recovery and rest periods were conducted while the subjects sat in chairs.   Blood samples were taken every 15 minutes during the exercise and every 30 minutes during the recovery period.  Their respiratory gas and heart rates were monitored continuously throughout the trial.男人每次演出审判在同一时间经过一天一夜空腹。他们行使对单一脚踏车（单车机） ，在普遍推荐运动处方的60 ％最大摄氧量。恢复和休息时间进行，同时受试者坐在椅等。血液样本，每15分钟演习期间，每30分钟在恢复期。他们的呼吸气体和心率连续监测整个审判。

Summary of Results 结果摘要

The Repeated trial showed a greater amount of lipolysis (fat breakdown) than did the Single trial.  This Repeated trial also had a pronounced increase in free fatty acids and glycerol (chemical compounds that are released when stored fat is used) concentrations in the final 15 minutes of exercise, whereas these concentrations only progressively increased throughout the Single trial.  Also, the second half of the Repeated trial showed a significantly greater epinephrine response while also having a rapid decrease in insulin concentration as a result of lower plasma glucose.  This combination of high epinephrine and low insulin concentration may have also increased the lipolysis.  There was also enhanced fat oxidation in the recovery period of the Repeated trial than in the Single trial, but this result may be because the free fatty acids concentration was already high before the recovery period.反复试验结果表明，较大数额脂肪（脂肪细目）比单一审判。这个反复试验，也有明显增加，游离脂肪酸和甘油（化学化合物释放时脂肪储存使用）的浓度，在最后15分钟运动，而这些只有浓度逐渐增加整个单一审判。同时，下半年的反复试验表明，大大肾上腺素反应，同时也有快速下降的胰岛素浓度由于低血糖。这种结合高甲肾上腺素和低胰岛素浓度也可能增加脂肪。还有加强脂肪氧化恢复期反复试验比在审单，但这个结果可能是因为游离脂肪酸浓度已经很高，然后回收期。

Conclusions 结论

The American College of Sports Medicine recommends moderate exercise for the duration of 45 to 60 minutes to ensure a sufficient amount of energy is depleted in obese individuals.  This has caused a greater focus on extending exercise sessions in order to burn more fat.  However, this study shows that this method may not be the most effective way to enhance fat metabolism, as splitting up a long bout of exercise with a rest period burns more fat than a continuous bout of exercise.  This study could help with the practical application of implementing new exercise methods in order to better manage and control weight in individuals in the future.美国大学运动医学建议适度运动时间45至60分钟，以确保有足够数量的能源消耗是肥胖。这种现状已引起了更加注重扩大演习会议，以燃烧更多的脂肪。然而，这研究表明，这种方法可能不是最有效的方式，以提高脂肪代谢，分裂长布特运动与休息烧伤脂肪比连续波演习。这项研究可能有助于与实际应用实施新的演习的方法，以便更好地管理和控制权的个人，在未来的。
