其他摘要：It was analyzed in what measurement the characteristics of the task in small side games influence the perception of effort(RPE) and his relation between the time of game and the RPE the type of tasks. Ten minibasketball players performed 50 tasks (10training sessions, 450 records RPE, 5 with duration of 8, 10 or 12 minutes). Based on the description 7 variables were codified: Aim:(Assault / Defense / Compound), Duration: (8 minutes / more than 8 minutes), Space: (Track completes / 1/2 Track / 1/4 of Track),numerical Equality: (Without rival / numerical Inequality / numerical Equality), Transition: (If / Not), Player of support: (If / Not),Relation between players: (attackers[n] x defenders[n]). No parametric analysis and an analysis of the variable RPE in function of thecharacteristics of the task with logistic multinomial regression from the RPE were used. RPE's average in all the variables were 6.87 ±1.76. Four variables contribute the model: Time of the task (X2 = 183.49; df= 8; p < .001), Relation among players (X2 = 63.71; df=10; p < .001), Transition (X2 = 15.37; df= 2; p < .01) and the Aim (X2 = 9.68; df= 4; p < .05). The % of classification of the model forthe group RPE (8-9), 90.1 % and for the group RPE (0-6), 71.6 %. The total percentage of classification predicted was 66.4. The tasksof 8 minutes in the group of RPE (0-6) have more possibilities of having RPE lower than those of any more 10 or 12 minutes. The tasksof attack have more possibilities of having a lower RPE. The characteristics of tasks influence the RPE. More than 8 minutes favor avery high RPE when the presence of attackers and defenders in 1x1 and 2x2 exist.
