Relationships between rating of perceived exertion and blood indices during training sessions of various intensity in female taekwondo players

Abstract

Exercise stress induced by a training session may be estimated quantitatively using basic two kind of ways, subjective self-reported feelings and objective parameters. One of the most widely used subjective indicator of somatic or psychological stress is state anxiety. Long since is known, that state anxiety [1-7] is higher in scores for more intensive and ex haustive bouts, but tended to decrease during short-lasting recovery. Another similar indicator of perceived physical fa ti gue induced by exercise is Rating Perceived Exertion (RPE). During long-lasting and endurance athletes like triathlon competition RPE significantly and negatively correlated (r=-0.911) with speed of run segments, and positively (r=+0.826) with overall race time. State anxiety prior to this event was higher than that at neutral condition [8]. It should be stressed, that both state anxiety and RPE reflex current feelings, but they are closely related to post effort bodily sensations. For this reasons these variables correlated significantly with some objective, physiological parameters, like heart rate and blood lactate concentration (LA) [9-14]. Interestingly, that various exertions are varied by their intensity and time duration de monstrated differentiated contribution of RPE for exercising body extremities, and for breathing effort, associated especially with experience of the sensation of shortness of breath and breathlessness. That latest symptom is expressed as chest RPE, while RPE extremities is often related to local pain and fatigue which are expressed as impairment of power output [11-14]. These symptoms are noted for instance at the end of Wingate-test and other anaerobic bouts. During an interval training overall RPE, aggregated lactate and HR values after several intensive efforts are useful tools for estimation of individual training tolerance/adaptation among exercising athletes. More comprehensive studies on biological res ponse to a single training involve also hormonal behavior in capillary blood. However, decision-making regarding the use of hormonal tests is cost-dependent and as well as depend-
