The control group performed exercises with no variability in practice conditions and the experimental group performed exercises with contextual interference by series. They trained for 6 weeks, twice a week (30 minutes sessions), on ball control and shooting at goal tasks. Three evaluations were made, one initial, one intermediate and one final and were carried out two weeks apart. Both groups had the same amount of repetitions during the practice sessions. The experimental group improvement regarding ball control was statistically significant from the control group and the experimental group also hit the goal significantly more than the control group. These results allow us to suggest that adding variability to practice may lead to technical improvements in young football players and that variability in practice may potentialize an adaptive behavior to the environment.engAcquisitionAdaptationContextual interferenceDifferential learningFootballMotor skillsStabilizationVariabilityEnhancing practice efficiency through contextual interference in youth footballmaster thesis202333647
