Brief Summary

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.

Conditions

Acute Exercise and Addictive Behavior

Outcome Measures

Primary Outcomes (1)

• Attentional Bias (AB) to chocolate using a modified visual dot probe task (Kemps et al, 2009)

  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.

  15 minutes

Secondary Outcomes (3)

• Affective Valence measured by The Feeling Scale (Hardy & Rejeski, 1989)

  1 minute

• Affective Activation measured by the Felt Arousal Scale (Svebak & Murgatroyd, 1985)

  1 minute

• Cravings for chocolate using the State Food Cravings Questionnaire (Cepeda-Benito et al, 2000)

  5 minutes
