In other notable work, Bryan and her collaborators surveyed cannabis users living in states with full legal access to find out whether cannabis use shortly before and/or after exercise affects enjoyment of and motivation to exercise. The researchers were specifically interested in comparing users who consumed cannabis shortly before or after exercise (co-users) with those who did not. They designed a simple questionnaire that asked people general questions about themselves, their marijuana use, and working out. Almost 82% of participants reported that they used cannabis around the time of their workouts. These individuals tended to be younger and more often male than those who did not use marijuana in conjunction with exercise. After controlling for these differences, co-users reported engaging in more minutes of exercise per week than non-users, while also reporting greater enjoyment of exercise and increased motivation to exercise. The study did not look at which kind of cannabis (edibles, smoked flower, etc.) people use alongside exercise, however, more research is already in the works at CU Boulder, comparing the activity levels of older adults who use cannabis with those who do not. Bryan's interest in life-style research led her into studies of the effects incentives might have on healthy eating. Her team had participants record their stress levels and the number of fruit and vegetable servings they ate each day for three weeks. One group received a dollar each time they ate a serving of fruit or vegetables, the other did not. On days when subjects reported feeling stressed, those who were being paid maintained their intake while those who weren't ate fewer servings of fruits and vegetables. Participants who received cash incentives maintained their daily fruit and vegetable consumption, even when stressed. Her studies suggest that incentives may be a novel method for buffering against the negative effect of daily stress on eating a healthy diet. Representative publications Bryan, A. D., Aiken, L.
