研究概览
简要总结
The study will use stress inducing tasks to determine if there are significant improvements in mood, chocolate cravings, and attentional bias to chocolate in overweight/obese chocolate abusers following rest and a bout of high intensity interval exercise.
详细描述
The purpose of this research study is to investigate whether a single high intensity interval exercise (HIIE) bout, following two stress-inducing tasks, reduces addictive behavior to chocolate. Volunteers must complete the consent form before being able to participate in two days of testing (exercise day and control day) which will be presented in randomized order. The two days will be separated by a one to 7 day washout period. Subjects will be required to submit a three day chocolate diary then abstain from chocolate on the 4th day. They will also be asked to record everything they eat and drink on the day before and the morning of the study and list three types of chocolate they crave most. Two stress-inducing tasks will be performed on both days followed by completion of either 26 minutes of HIIE or seated resting condition followed by the completion of two mood and craving questionnaires. They will finally be asked to complete a task that measures the amount of attention they pay to chocolate. Statistical analyses will be conducted to determine the effect of either exercising or not on addictive behaviors to chocolate.

结局指标
主要结局
Attentional Bias (AB) to chocolate using a modified visual dot probe task (Kemps et al, 2009)
时间窗: 15 minutes
AB will be measured using a modified visual dot probe task, which consists of measuring reaction times to neutral images versus chocolate images (Kemps et al, 2009). Neutral images will consist of non-chocolate related items (i.e. office supplies). After 5 practice trials, 60 critical trials will be displayed which consist of either chocolate or neutral images (presented side by side). A black fixation cross will appear behind one of the images, and the subject has to respond as quickly as possible to which image the cross is located behind. The faster the subject responds to the cross behind the chocolate image, the higher their attentional bias is to chocolate. AB will be measured on both days following both the exercise and control conditions.
