Objectives The purpose of this study was to examine the effects of a peer-based mental imagery intervention on the self-determined motivation and cardio-respiratory fitness of university enrolled women. Design Randomized controlled trial. Method 43 University enrolled women were randomized to peer-mentored or peer-mentored plus mental imagery conditions while 32 completed three meetings with peer-mentors and post-testing (Mage = 19.91; SD = 1.70). Results Significant improvements in cardio-respiratory endurance, ratings of perceived endurance, and self-determined motivation to exercise were observed across both study conditions. Participants assigned to the peer mentored plus mental imagery condition reported significantly greater increases in self-determined motivation to exercise at post-test compared to those in the peer-mentored condition. Conclusions Peer-based interventions are a viable way to improve fitness and health outcomes while mental imagery appears to be associated with increases in autonomous forms of exercise motivation.
Sedentary behavior, physical inactivity, and obesity are primary factors in global morbidity and mortality (World Health Organization, 2012). According to the World Health Organization (WHO), physical inactivity accounts for 6% of deaths worldwide primarily due to diabetes, breast and colon cancers, and ischemic heart disease. There is broad consensus that participation in regular physical activity reduces risk of coronary heart disease, diabetes, stroke, hypertension, and depression (Physical Activity Guidelines Advisory Committee, 2008). Physical activity is also a key determinant of energy balance and is therefore an important part of weight control strategies. Finding ways to promote the initiation and maintenance of physical activity behavior is an important global public health challenge. Declines in physical activity (PA) begin in late childhood and show a significant drop during early adulthood. Population surveillance data in the United States (U.S.) shows that approximately 24.8% of 18–24 year old adults report engaging in no leisure-time physical activity, compared with 27.8% of adults aged 25–44, 32.5% of those aged 45–64, and 41.8% of older adults aged 65–74. Amongst 18–24 year olds, greater than 40% do not follow recommended guidelines of accruing 150 min of moderate intensity aerobic physical activity per week, or 75 min of vigorous intensity, or an equivalent combination (United States Department of Health and Human Services, Physical Activity Guidelines Advisory Committee, 2008). Likewise, Healthy Campus 2020 identified physical inactivity and fitness as 1 of 10 student health priority areas for university enrolled students (American College Health Association, 2012). In short, intervening with the university population may help individuals establish sustained patterns of physical activity which may impact long-term health (Keating, Guan, Pinero, & Bridges, 2005). It is also important that a smaller proportion of adult women meet public health guidelines, and PA differences between men and women become increasingly exaggerated over the life course (USDHHS, 2010). Among ethnic minority women in the U.S., African American, Hispanic, and Native Indians are among the least active segments of the population for all age groups. This is unfortunate because women generally live longer than men but also suffer from a greater number of disabling physical and mental conditions and report lower health-related quality of life as compared to men (Boiche et al., 2008 and Guay et al., 2003). PA is one possible pathway that may explain some of the differences between men and women in self-rated health and quality of life. While some data suggests that university enrolled women are more active than those not enrolled, there have been calls in the literature for increased research attention to university students in order to help young adults establish and maintain habitual PA (Keating et al., 2005). For these reasons, interventions targeting women during early adult life transitions, such as university enrollment, represent an opportunistic time to promote physical activity. Such efforts could help women develop self-management skills important for the maintenance of life-long physical activity behavior. The United States Task Force on Community Preventive Services recommends that programs attempting to help individuals incorporate PA into their daily routines should include self-management skills such goal setting, self-monitoring of progress towards goals, problem solving to maintain behavior change, behavioral reinforcement through self-reward, and positive self-talk (Guide to Community Preventive Services, 2012). Another self-management skill, mental imagery, is emerging as a viable tool that may help increase exercise behavior with adults. Mental imagery can be defined as “The creation or recreation of an experience generated from memorial information, involving quasi-sensorial, quasi-perceptual, and quasi-affective characteristics, that is under the volition control of the imager, and which may occur in the absence of the real stimulus” (Morris, Spittle, & Watt, 2005, p. 18). This definition acknowledges the role of memory, sensory experience, volition, and emotions. Finding effective ways to deliver mental imagery and other self-management skills is an important theoretical and practical public health challenge.

The continued study of mental imagery in PA settings is clearly warranted. Mental imagery, like peer-based PA interventions, can be readily applied in school, clinical, and community settings. Mental imagery can also serve as the primary intervention approach or it can be used as an adjunct to other aspects of an intervention (see e.g., Buman et al., 2011 for an example of the latter). It is also possible to implement mental imagery interventions using the internet (Murru & Martin-Ginis, 2010) creating the potential to intervene with large numbers of individuals. The findings observed here were consistent with previous investigations using peer-mentored approaches and mental imagery (Buman et al., 2011, Duncan et al., 2012 and Martin Ginis et al., 2013). Generally, peer mentoring appears to be a viable way to increase exercise behavior and cardio-respiratory endurance while mental imagery is associated with increases in self-determined motivation to exercise. More sophisticated studies with larger samples that incorporate mental imagery into peer-based or other intervention approaches to increase exercise behavior are warranted.
