Association between motor competence, and the rating of perceived exertion in male young adults

The purpose of this study was two-fold: (i) to analyze the relationship between motor competence (i.e., a person's ability to be proficient in different gross motor skills) and the rating of perceived exertion (RPE), which represents the physiological and psychological responses during training, in young adults, and (ii) to compare RPE between participants with high and low motor competence. Forty-eight male young adults (22.01 +/- 2.43 years) participated in this study. Participants were randomly divided into several teams of three players to perform a small-sided game for 25 min (Goalkeeper + 2 x 2 + Goalkeeper) in which the RPE was collected. Then, motor competence was assessed through six tests assessing three main components: stability (Jumping Sideways and Shifting Platforms); locomotor (Standing Long Jump and Shuttle Run), and manipulative (Velocity of Ball Kicking and Throwing). Motor competence was negatively associated with RPE (r = -0.64; p < 0.001). Moreover, locomotor, stability, and manipulative components were negatively associated with RPE (all, p < 0.05). Furthermore, upon comparing groups with low and high levels of motor competence, we observed significantly higher RPE values (p < 0.001; d = 0.32) in the low motor competence group. The findings from this study suggest that individuals with higher levels of motor competence may report a lower RPE during exercise. This information is valuable for coaches as improving levels of motor competence may potentially lead to increases in on-field performance.
