概括
在饮食障碍 (ED) 中,不适应性炼可能不会减少消极情绪,但会增加炼前后的积极情绪. 这表明运动预期,而不仅仅是它的表现,对于EDS患者来说可能是有益的.
科学领域:
- 心理学 心理学 心理学
- 饮食障碍 饮食障碍 饮食障碍 饮食障碍
- 运动科学 运动科学
背景情况:
- 不适应性炼 (MalE) 是一种常见的饮食障碍 (ED) 症状,与较差的结果有关.
- 情感调节理论表明,MalE减少了负面情感,但证据是混合的.
- 很少有研究将客观活动监测与ED群体的生态瞬间评估 (EMA) 结合在一起.
研究的目的:
- 为了检查影响轨迹 (负影响[NA]和积极影响[PA]) 围绕运动在妇女与EDs.

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

01:29The Influence of Cognition on Affect
175
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...
