Resurgence is a behavioral principle that can account for switching of fitness behaviors.
By definition, resurgence = When previously extinguished target behavior “resurges” when a more recently reinforced target behavior is extinguished. Loosely speaking, you get bored of one activity and go do something else.
Resurgence Explained
Phase 1
- Running receives reinforcement and occurs at a high rate
- Weightlifting does not
Phase 2
- NOW, weightlifting receives reinforcement and occurs at a high rate
- Running no longer produces the same reinforcers
Phase 3
- NOW, when weightlifting no longer receives reinforcement…
- Running “resurges” and comes back.
Resurgence In Practice
This behavioral principle can be used to explain why people switch back-and-forth between certain exercises. Remember, the reinforcers will likely vary across the amount, type, and immediacy of these activities. Running may produce an immediate “runner’s high” while weightlifting produces delayed strength gains and social praise. And reinforcers differ for everybody, all the time.
The next time that you bounce between exercises, consider what reinforcers are no longer produced from your previous exercise. Especially returning back to an “old” habit.
