Parámetros perceptuales y afectivos como indicadores del punto de transición aeróbico-anaeróbico en la caminata en ritmo autoseleccionado

Abstract

Introduction: The low adherence to physical activity programs is widely registered, mainly in programs with vigorous intensities. Studies have been suggesting that exercises accomplished with predominantly aerobic supply could promote pleasant perceptual and affective answers. In spite of that, little is known about these answers during the self-selected walking speed and if they present a relation with those answers verifi ed in the aerobic-anaerobic transition point. The objective of that study was to investigate the perceptual and affective answers associated to the aerobic-anaerobic transition point (ventilatory threshold, VT) and to verify if these answers present differences in relation to the perceptual and affective answers obtained during the accomplishment of the self-selected speed by adult women. Materials and Methods: 45 previously sedentary individuals have been investigated and have accomplished: a) maximum incremental treadmill test; and b) test of 20min of walking in self-selected speed. The subjective effort perception SEF) and the affective valence (VA; self-reported pleasure/displeasure) were measured in each interval of 1min. Results: The results showed that the scores of SEF (12.2±1.7) and VA (2.64±1.68) in LV were similar to those scores of SEF (11.9±1.4) and VA (2.60±1.64) during self-selected walking speed (p>0.05). Discussion: In this way, we can concluded that the SEF psychological parameters and VA could be used as indicators of the aerobic-anaerobic transition point during the walking realized in self-selected speed by sedentary adult women.
