Validation of the OMNI RPE Seven Day Exertional Recall Questionnaire

The present study examined the validity of the Seven Day Recall Questionnaire among recreationally active men and women.

Initially, participants completed a level walk (2.5 mph [4.0 kph]), hill walk (3.5 mph [5.6 kph], 5% grade), and run (5.0 mph [8.0 kph], 2.5% grade). Seven days later, participants were given the Seven Day Recall Questionnaire and rated their perceived exertion associated with the exercise bouts. Participants then repeated the same exercise bouts as in Session 1, and the OMNI rating of perceived exertion (RPE) was estimated.

Concurrent validity indicated that for both men and women, respectively, the RPE-Overall (r = .48, r = .70), RPE-Leg (r = .43, r = .66), and RPE-Chest (r = .47, r = .66) derived from the Seven Day Recall Questionnaire distributed as a function of oxygen consumption. RPE-Overall (r = .61, r = .76), RPE-Leg (r = .56, r = .72), and RPE-Chest (r = .61, r = .72) from the Seven Day Recall Questionnaire distributed as a function of heart rate. Convergent validity coefficients between the perceptual responses from the Seven Day Recall Questionnaire and the recall/criterion session were: level walk (r = .53-.87, r = .51-.80), hill walk (r = .65-.79, r = .56-.64), and run (r = .60-.68, r = .68-.78) for men and women, respectively.

Concurrent and convergent evidence partially supports the utilization of the Seven Day Recall Questionnaire to recall the relative intensity of walking and running exercise sessions conducted 7 days prior.
