Physical activity recall questionnaires are important tools to quantify physical activity patterns and relating these patterns to disease risk. However, of the movement components that comprise physical activity, intensity is the most difficult to directly and objectively measure.
PURPOSE: The present investigation examined the validity of a post-event recall questionnaire to measure the perception of physical exertion during a circuit exercise program.
METHODS: Forty (21.1 ±2.7 yrs) recreationally active females (n=22) and males (n=18), with no prior knowledge of OMNI RPE, underwent a circuit program consisting of in counterbalanced order: (I) cycle ergometry at 50% and 75% VO2peak, and (II) bicep curls at 65% and 90% 1-RM. Seven days later, subjects rated their perceived exertion associated with each exercise bout using the Exertional Recall Questionnaire. The subjects reported OMNI RPEs for the overall body (O), legs (L), and chest/breathing (C) for the cycle exercises, and OMNI RPEs for the overall body (O) and arm (A) for the bicep curl exercises. Following completion of the Exertional Recall Questionnaire, subjects were given standardized instructions for the OMNI RPE Cycle and Resistance Scales and repeated the circuit program. OMNI RPEs were then measured during the exercise bouts (the Criterion).
RESULTS: Three-factor analyses of variance indicated that Recall and Criterion RPE-O, and L did not differ significantly at both cycle exercise intensities (p=0.064 and 0.169). Recall RPE-C was significantly lower than Criterion RPE-C at both cycle exercise intensities (p=0.010). Three-factor analyses of variance indicated that the RPE-O and A for the Recall procedure were significantly less than the Criterion procedure (p<0.001) for both the lighter and heavier resistances.
CONCLUSIONS: Recreationally active females and males with no prior knowledge of OMNI RPE were able to recall their perceived exertion (overall body and legs) experienced during non-weight bearing (cycle) aerobic exercise performed seven days previously. The Recall procedure is valid for non-weight bearing aerobic exercise. However, subjects under-estimated Recall RPE-O and A for upper body resistance exercise. These responses question validity of the Recall RPE procedure for single joint arm resistance exercise.
