这项研究的目的有两个：(1)检验中低强度、短持续时间的体力活动对主观食欲的影响；(2)确定正常体重男孩在喝完葡萄糖和乳清蛋白饮料后30分钟吃披萨时，通风阈值(VET)和能量摄入量之间的关系及其作用。在14名男孩(年龄：12.5+/-0.4岁)中，根据兽医的设计，在12分钟步行方案之前和之后测量了主观食欲。在另一个单独的场合，测量食物摄入量(F1)和主观食欲，以响应Splenda(R)蔗糖对照组、葡萄糖或乳清蛋白加水250毫升的甜味预负荷，在标准化早餐后2小时随机给每个男孩喂食。体力活动后主观平均食欲和预期食物消费得分增加。在饮用葡萄糖和乳清蛋白饮料后30分钟进食比萨饼午餐时，VET与F1呈正相关。与对照组相比，午餐时葡萄糖和乳清蛋白类似地降低了FI。总而言之，在男孩中，通过低到中等强度、短时间的体力活动可以增加食欲，而葡萄糖和蛋白质预负荷后的FI与健康水平呈正相关。(C)2007爱思唯尔有限公司。保留所有权利。
The purpose of this investigation was twofold: (1) to examine the role of low- to moderate-intensity, short-duration physical activity on subjective appetite and (2) to identify the role of and associations between ventilation threshold (VeT) and energy intake at a pizza lunch 30 min after glucose and whey protein drinks in normal weight boys. In 14 boys (age: 12.5 +/- 0.4 years) subjective appetite was measured before and after a 12 min walking protocol designed to determine physical fitness based on the VeT. On a separate occasion food intake (F1) and subjective appetite were measured in response to sweetened preloads of either a SPLENDA (R) Sucralose control, glucose or whey protein made up to 250 ml with water, given in random order to each boy, 2 h after a standardized breakfast. Subjective average appetite and prospective food consumption scores increased after physical activity. VeT was positively associated with F1 at a pizza lunch consumed 30 min after glucose and whey protein drinks. Glucose and whey protein reduced FI similarly at lunch compared with control. In conclusion, appetite is increased by low- to moderate-intensity, short-duration physical activity and FI following glucose and protein preloads is positively associated with fitness levels in boys.
