Objectives: To determine the effect of self-efficacy manipulation on the movement efficiency, rate of perceived exertion (RPE), and affective state of runners while running on the treadmill at a constant submaximal pace.
Methods: 20 trained male and female runners were randomly assigned to experimental (self-efficacy manipulation) and control groups. Participants first filled out a pre self-efficacy questionnaire and the positive affect negative affect schedule (PANAS), and then completed a 20 minute run on the treadmill running at 75% of their peak treadmill running speed. After 10 minutes, their oxygen consumption (VO2), heart rate (HR), and RPE was recorded. Participants (n=10) in the experimental group were then given motivational feedback in the form of verbal persuasion, which was recurrent every 2 minutes onwards. No feedback was given to the control participants. VO2, HR, and RPE were recorded for all participants at 10, 12, 14, 16, 18, and 20 minutes. A post-test questionnaire measuring the participant's level of self-efficacy and the PANAS was filled out.
Results: Successful manipulation if self-efficacy (p < .05) led to significant interaction between groups and measurement times in VO2 (p < .001), with the control group showing an almost significant (p = .027) increase and the experimental group a significant decrease (p < .01) in VO2 across times. No differences were found in HR or RPE (p > .05). Positive affect tended to increase and negative affect to decrease more from pre- to post-test in the experimental relative to the control group (p = .055).
Conclusions: Verbal persuasion is an effective measure of altering one's self-efficacy which results in greater movement efficiency.
