RESUMO:

The complex human behavior of physical exercise involves, in addition to cognitive, physical and emotional processes, interoceptive factors that influence the control of physical exercise intensity. In this sense, recent studies demonstrate a human interindividual variability in the perception of the corporal signals, this perception is denominated like interoception. In addition, recent evidence exposes the influence of interoceptive perception on behavior during physical exercise. However, studies that use interoception as an influencer in the regulation of physical effort have divergence in the sample and in the instruction given to individuals. Therefore, the present study verified the influence of interoception (accuracy and interoceptive awareness) on the regulation of physical effort, performance and psychophysiological responses during two exercise conditions, with different instructions, in adolescents. A total of 45 adolescents, aged 14 to 17 years, were separated by the Interoceptive accuracy level: high accuracy (n = 20) and low accuracy (n = 25); and in the second stage by the level of Interoceptive consciousness: High consciousness (n = 28) and Low consciousness (n = 17). All were submitted to anamnesis, anthropometric evaluation, maturational stage, preference questionnaire and exercise intensity tolerance (PRETIE-Q), stress questionnaire, anxiety and depression questionnaire (DASS-21), resting heart rate variability and aerobic fitness (leger test). Subsequently, they were submitted (in random and crossed order) to two conditions of physical exercise of race, in which they differed as to the instruction oriented to the volunteer, a self-selected one (you have 10 minutes of exercise); and another that seeks the best performance of the individual (you have 10 minutes to give as many laps as possible). During exercise, the heart rate, the subjective perception of effort (PSE) and the affective response of the volunteers were measured, with the last two being every two minutes. Normality was tested by Shapiro-Wilk and z-score (asymmetry and kurtosis). The T-test for independent samples and Mann-Whitney were used to compare the groups. The Generalized Estimating Equation model verified the possible differences between PSE responses and affection during the exercise. In stage one, there was a significant difference between the groups in the two exercise conditions, the distance covered (p <0.05), and no group and time interaction with the PSE responses and affective response (p> 0.05). In step two, there was a significant difference in distance between the groups only in the condition that sought the best performance of the subjects (p = 0.026), the self-selected condition being statistically similar (p = 0.097), and the affective response there was no group and time interaction (p = 0.026), and PSE in the exercise that sought the best performance, there was group and time interaction (p = 0.026), similar to PSE in the self-selected exercise (p = 0.643). We conclude that subjects with high Interoceptive Accuracy present greater conservation when selecting the intensity of physical exercise, regardless of orientation. However, in study two, this behavior is only similar during the condition in which the volunteers seek the best performance.
