Abstract:
Currently, exercise prescription relies heavily on parameters included in the FITT principle: frequency, intensity, time (duration), and type of exercise. In this paper, the benefits of including timing (FITT+T), referring to when exercise is performed in relation to meal-time, is discussed. Current research indicates that timing is outcome-specific. Total energy and lipid intakes, and postprandial hypertriglyceridemia can be reduced when exercise is performed pre-meal, while glycemic control is improved with post-meal exercise. Although findings indicate that timing can aid in obesity management and cardiometabolic-risk reduction, most research involves adult subjects and acute investigations. Some research with children, concerning the effect of timing on appetite, indicates that pre-meal exercise helps regulate energy balance, but also identifies key differences in response compared with adults. Overall, current findings support the benefits of timing, but research is required to establish guidelines that are specific to the pediatric population and their health-related goals, while incorporating other FITT components.
摘要:
目前,运动处方在很大程度上依赖于FITT原则中包含的参数:频率,强度,时间(持续时间),锻炼的类型。在本文中,包括时机的好处(FITT+T),指的是何时进行运动与进餐时间有关,正在讨论。目前的研究表明,时机是特定于结果的。总能量和脂质摄入量,餐前锻炼可以减少餐后高甘油三酯血症,而餐后运动改善了血糖控制。尽管研究结果表明,时间安排可以帮助肥胖管理和降低心脏代谢风险,大多数研究涉及成人受试者和急性调查。一些对孩子的研究,关于时机对食欲的影响,表明餐前锻炼有助于调节能量平衡,但也确定了与成年人相比在反应方面的关键差异。总的来说,目前的发现支持时机的好处,但是需要研究来建立针对儿科人群及其健康相关目标的指南,同时包含其他FITT组件。
