Two studies examined the trustworthiness of commonly used measurement scales for ratings of perceived exertion (RPE) and state attentional focus (SAF) during exercise. In Study 1, participants (N = 24, 14 female) performed a treadmill graded-exercise test. The order of scale presentation during the task was manipulated (i.e., RPE followed by SAF or vice versa). In Study 2 the same order manipulation was used while participants (N = 70, 36 female) performed a stepping task for three consecutive trials. Additionally, time intervals between scale presentations were manipulated (i.e., 30 sec, 60 sec, or 90 sec) and counterbalanced between trials. Non-significant order effects of RPE and SAF emerged in both studies; however, a more frequent presentation of the two scales (30 sec and 60 sec) yielded higher RPE scores and increased associative attentional focus than a less frequent presentation (90 sec). The authors recommend minimizing measurement interruptions during the measurement process. [ABSTRACT FROM PUBLISHER]
