Exercise and Mental Health (2016-2017)

College is a key developmental period for making decisions about whether one is going to lead an active or sedentary lifestyle. This is a critical decision: exercise is associated with a variety of mental health benefits including reduced stress reactivity; depressive, anxious and ADHD symptoms; and improvements in body image, self-esteem and academic performance. However, exercise is not beneficial to everyone at all times: some individuals exercise to a compulsive degree. Thus, research is needed to determine moderators (e.g., biological, psychosocial and exercise characteristics) of the relationship of exercise on positive mental health. Researchers need to better understand who will most benefit from exercise and for whom is it contraindicated. Knowledge of moderators of exercise benefit would help educators tailor exercise programs to those whom would most benefit and design specialized programs for vulnerable individuals.

This Bass Connections project team examined the impact of a strength training intervention on indices of mental health and body image in college students. The team conducted a study to assess the effects of the intervention on positive body image (PBI) and to examine factors that may be associated with greater improvement in PBI. Study participants were male (n=12) and female (n=26) students ages 18-25 who were previously inactive with no exercise limitations. Participants completed an eight-week program that included three full-body workouts per week and alternated biweekly between a traditional workout of free weight exercises and a functional workout using body weight and balance exercises.

Participants reported a significant improvement in body appreciation and satisfaction with physical capabilities. Males had lower pretest body image than females. Exercise motivations were significantly correlated with changes in PBI. Individuals with higher pretest appearance motivation and weight management motivation for exercise experienced less improvement in satisfaction with one’s capabilities. Participants with higher health motivation and strength and endurance motivation for exercise had less change in body surveillance.

Future studies should examine gender differences in PBI, compare changes in PBI for different types of exercise (e.g., cardio vs. strength training) and examine whether PBI confers protection from body image-related disorders.

Team members also created an Activity Finder application incorporating an extensive repository of physical activity opportunities in the local area into a searchable database for health practitioners, in order to help them provide more precise physical activity recommendations to their patients.
