Modeling in Exercise
- Modeling in a strong source of self-efficacy; exercise models, such as aerobics
instructors, personal trainers, and other exercisers, may positively influence exercise
participations; they may assist exercisers in acquiring self-efficacy for exercise (we can
increase motivation and self-efficacy this way) – it has been shown that instructor has a
big impact on participation and self-efficacy
- Bray et al. (2001) recruited 127 women who were enrolled in a 10-week structured
group fitness program to complete self-report measures of self-efficacy and proxy
effia i.e. partiipats ofidee i their fitess istrutors ouiatio,
teaching, and motivating capabilities)
- The measures were completed in the third week and attendance was recorded through
the remainder of the program
- Results revealed a significant correlation between self- and proxy efficacy and a
significant influence of both types of efficacy on subsequent class attendance (higher
class attendance if higher self-efficacy)
- It appears the perceived capabilities of the instructor are related to the self-efficacy of
the exercise participants and that may also be an important predictor of exercise
behaviour
- In addition to expert models (e.g. fitness leaders), peer models may also be influential
for increasing self-efficacy for exercise
- Maddison et al. (2008) conducted an intervention aimed at increasing self-efficacy and
effort during a peak oxygen uptake (VO2) test among twenty patients with chronic heart
failure
- All participants in the study underwent two peak VO2 tests, conducted one week apart;
between the two tests, patients were assigned randomly to either an intervention or
control group
- The intervention group watched a 10-minute, coping-model DVD which included:
A. Clips of patients performing a peak VO2 test
B. Patient demonstrations and verbalizations about acquiring confidence to
perform the test
C. Patients offering strategies to cope with the required effort and overcome
discomfort that occurs during the test
D. Clips of a cardiologist who outlined the purpose of a peak VO2 test, the
importance of the diagnostic information, the importance of pushing for
maximal effort, and information about the safety of the test
- Patients in the control group did not view the DVD
