Outcome Measures

Primary Outcomes (2)

  • Change in relative reinforcing value (RRV) of physical activity

    RRV of physical activity will be assessed by evaluating the number of responses (mouse button presses) a subject is willing to complete to gain access to physical activity or a sedentary alternative.

    Week 0, Week 6, Week 10

  • Changes in preference for intense physical activity and tolerance for exercise discomfort

    Changes in preference for intense physical activity and tolerance for exercise discomfort will be assessed by self-report questionnaire responses to the Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q).

    Week 0, Week 6, Week 10

Secondary Outcomes (10)

  • Change in minutes of physical activity, as assessed by activity tracker

    Week 0, Week 6, Week 10

  • Changes in perceived support for physical activity from friends and family members

    Week 0, Week 6, Week 10

  • Changes in perceptions of how much exercise satisfies autonomy, relatedness, and competence needs

    Week 0, Week 6, Week 10

  • Changes in intrinsic, external, interrogated, identified, introjected and amotivation for physical activity

    Week 0, Week 6, Week 10

  • Changes in perceived effort expended during exercise

    Week 0, Week 6, Week 10

  • +5 more secondary outcomes

Study Arms (3)

High Dose Exercise vs Sedentary Option

OTHER

Relative Reinforcing Value of high dose exercise (300 kcal expenditure per session) versus sedentary activity will be determined.

Other: High Dose Exercise (300 kcal)Other: Sedentary Option

Low Dose Exercise vs Sedentary Option

OTHER

Relative Reinforcing Value of low dose exercise (150 kcal expenditure per session) versus sedentary activity will be determined.

Other: Low Dose Exercise (150 kcal)Other: Sedentary Option

No Exercise vs Sedentary Option

OTHER

Relative Reinforcing Value of no exercise (0 kcal expenditure per session) versus sedentary activity will be determined.

Other: No Exercise (0 kcal)Other: Sedentary Option

Interventions

Subjects will participate in 3 physical activity sessions per week expending 300 kcal per session and rate their liking of exercise.

High Dose Exercise vs Sedentary Option

Subjects will participate in 3 physical activity sessions per week expending 150 kcal per session and rate their liking of exercise.

Low Dose Exercise vs Sedentary Option

Subjects will participate in 3 sessions per week expending 0 kcal per session and rate their liking of exercise.

No Exercise vs Sedentary Option

Subjects will rate their liking of sedentary activities (reading magazines, playing word games, puzzles) as an alternative to exercise.
