Abstract
The aim of this study was to identify the effects of format and task condition on heart rate
responses and technical/tactical performance measured by mathematical methods. Ten male
basketball players (14.75 ± 0.46 years old; 5 ± 1.4 years of training) from a Portuguese youth
regional league participated voluntarily in this study. Results revealed that the format had
significant main effects and large effect size (Pillai’s Trace = 0.692; F(10,78) = 4.124; p = 0.001; 𝜂!

= 0.346; Power = 0.996) on heart rate responses and technical/tactical performance. It was also
found that task conditions had a significant main effects and a large effect size (Pillai’s Trace =
0.623; F(10,78) = 3.526; p = 0.001; 𝜂!
! = 0.311; Power = 0.988) on heart rate responses and
technical/tactical performance. Smaller formats had the highest heart rate responses, volume of
play, attacks with ball, efficiency index and performance scores. The task condition with two
targets had the highest heart rate responses and the task with endline had the highest values of
volume of play, attacks with ball, efficiency index and performance score. In sum, it was found
that smaller formats are similar to anaerobic workouts and to can be used to increase technical
actions. The bigger formats are appropriated to high intensity aerobic workouts and to can be used
to increase the complexity of the task.
