Chapter 12

1. To gain a better understanding of the relationship between exercise and affect, conduct a self-experiment. Over the course of two weeks, do a simple rating of energy and tension before and after a scheduled exercise session. Use a rating from 1 to 7 for each, with 1 being none or very little and 7 being a great deal or very much. On nonexercise days, rate yourself with the same scale at approximately the same times of the day that you would exercise. After the two-week period, compare the ratings from before and after the exercise sessions. What differences are apparent? What do you see when you compare the affect on exercise days with the affect experienced on nonexercise days?

2. Use the circumplex approach to examining affective responses. Using the circumplex diagram below, in which the dimensions of activation and valence are represented, complete the following tasks. Incorporate the following time points as appropriate:

Moderate ExerciseIntense Exercise
5 minutes5 minutes
15 minutes15 minutes
Immediately post-exerciseImmediately post-exercise
20 minutes post-exercise20 minutes post-exercise










  • Describe two different intensities of exercise, noting how they differ in terms of intensity. Label one type as “moderate” and the other as “intense.”
  • Draw the expected response to a 20-minute bout of the “moderate” exercise.
  • Draw the expected response to a 20-minute bout of the “intense” exercise, incorporating the same time points.
  • What are the major differences in the two drawings? Why do these differences occur?
