本研究考察了年龄和慢性体力活动状态对食欲和情绪状态的影响。由年轻的不活跃(YI)、年轻的活跃(YA)、年长的不活跃(OI)和年长的活跃(OA)的男性和女性组成的小组完成了问卷调查，每组人在一天的清醒时间内对食欲和情绪状态进行评级。O组最大耗氧量比Y组低20%(p<；0.001)，I组比A组低32%(p<；0.001)。O组的平均饥饿感(O4±1，Y5±1)和食欲(O3±1，Y4±1Au，P<；0.01)均低于Y组。运动组的Nadir觉醒(A3±1，I2±1au，P<；0.05)高于Y组。年龄较大的受试者的最低性唤醒、最低性愉悦和平均愉悦感较高(p<；0.05)。体力活动状况不会影响食欲或与年龄相关的饥饿感和食欲下降。体力活动组和老年组受试者的低谷唤醒程度增加，这与这些受试者经历的不那么极端的嗜睡是一致的。
This study examined the influences of age and chronic physical activity status on appetite and mood state. Groups of younger inactive (YI); younger active (YA); older inactive (OI); and older active (OA) men and women completed questionnaires each waking hour rating appetite and mood state for one day. Maximal oxygen consumption was 20% lower in O vs. Y (p<0.001) and 32% lower in I vs. A (p<0.001). Mean hunger (O 4±1, Y 5±1 arbitrary units (au), p<0.01) and desire to eat (O 3±1, Y 4±1 au, p<0.01) were lower in O vs. Y. Nadir arousal was higher for the active subjects (A 3±1, I 2±1 au, p<0.05). Nadir arousal, nadir pleasantness, and mean pleasantness were higher for the older subjects (p<0.05). Physical activity status does not influence appetite or the age-associated declines in hunger and desire to eat. The increased nadir arousal of the physically active and older groups of subjects is consistent with these subjects experiencing less extreme sleepiness.
