SELF-REPORTS OF EXERCISE EFFECTS ARE UNRELIABLE
Pothakos, K., & Kubitz, K. A. (1998). Effects of aerobic exercise and fitness on brain and self-reported activation. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 663.
Two hypotheses were evaluated:
- Brain activation and self-reported activation would increase during exercise and decrease after exercise.
- Aerobic fitness would moderate changes in brain activation and self-reported activation.
It was found that:
- Brain activation increased during exercise and remained elevated during recovery.
- Self-reported activation increased during exercise but returned to baseline during recovery.
- Aerobic fitness did not moderate the effects of exercise on brain activation or self-reported activation.
Implication. Self-reports of exercise effects are unreliable for actually estimating true activation states.
