Abstract

The aim of this research paper was to learn about the most effective Physical Education material resources to improve gross motor development of students aged from 6 to 9 depending on their gender and age. The sample of 982 schoolchildren was divided into three experimental groups according to the type of consumable material and a control group. The TGM-2 test procedure was used by means of a pre-test and a post-test after an intervention lasting 14 sessions. The difference in direct scores in the two areas (locomotor and object control) was higher in the experimental groups (p-value <0.05). This difference is higher with the use of alternative materials, followed by only balls and without balls in both educational stages and in both genders, except for second stage girls where the best results are found in the only balls experimental group of materials.
