Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The hypotheses detailed below are specific to the randomization of participants into the following 2 groups:
1. Moderate exercise (Experimental condition; MEG)
2. Passive sitting (Attention control condition; PSG)
Hypothesis 1: A bout of moderate intensity exercise will be associated with decreased smoking satisfaction after a temporary period of abstinence compared to a control condition.
Hypothesis 2: Smoking topographic measures will mediate the relationship between a bout of moderate intensity exercise and smoking satisfaction.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Smoking satisfaction is an immediately reinforcing effect of nicotine. Smoking satisfaction may outweigh the temporally distant adverse health risks of smoking (Cappelleri, Bushmakin, Baker, Merikle, Olufade, \& Gilbert, 2007). Varenicline, an alpha 4-beta-2 nAChR partial agonist, mimics the effect of nicotine by reducing cravings and withdrawal symptoms (Coe et al., 2005). A 12-week treatment period of varenicline has been shown to reduce smoking satisfaction (Jorenby et al., 2006). However, the effect of acute exercise on smoking satisfaction is not yet known.
Smoking topography is a key facet of smoking behaviour. Smoking behaviour can be subjectively or objectively measured by quantifying puff volume, maximum puff velocity, inter-puff interval, puff duration, number of puffs per cigarette and time to smoke a single cigarette. Smoking topography can estimate exposure to carcinogenic toxins present in cigarette smoking (Djordjevic, Hoffman, \& Hoffman, 1997). Evidence exists to support that exercise modifies smoking topography (Katomeri \& Taylor 2006; Mikhail, 1983; Reeser, 1983; Zacny \& Stitzer, 1985).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Moderate Exercise Group
The moderate exercise condition will involve participants waking briskly (equivalent to moderate intensity) on a treadmill for 10 minutes. Moderate intensity exercise is defined as 40-68% of heart rate reserve (HRR). Heart rate (HR) will be monitored using a Polar RS100 Heart Rate monitor to serve as a guide for participants to attain the appropriate intensity.
Moderate Exercise Group
Participants will be required to walk briskly (equivalent to moderate intensity) on a treadmill for 10 minutes.
Passive Sitting Group
The passive sitting condition will involve participants sitting passively in a chair for 10 minutes. Heart rate (HR) will be monitored in participants of the passive sitting group to help maintain group equivalency (with the moderate exercise condition) with regards to distraction effects and researcher contact.
Passive Sitting Group
Participants will be required to sit passively on a chair for 10 minutes.
