Resistance Training Based on Gamification in Children Aged 10-12 Years Old During Physical Education

For this investigation a total of ≃300 children (grades 5 and 6; 10-12 years of age) from 6 randomly selected schools in Valencia (Spain) will be enrolled during 8 weeks in one of the experimental groups (EG): EG1 (15' of RT Functional HIIT circuit program), EG2 (the same EG1 program but with a gamification approach) or CG (control group). Outcomes will include age and sex, maturity, PA profile, MF (assessed using an ad hoc battery), anthropometry and body composition (weight, height, sitting height, waist circumference and BMI) as well as the enjoyment and motivation during physical education. An interactive app in a digital device will be used for the gamification story, the point's registration with the personal children's avatar and content learning by flipped classroom. The hypothesis of the RETRAGAM study posits that children who participate in the gamified RT intervention will experience greater improvements in MF, body composition, motivation, and enjoyment compared to those who carry out the same intervention without gamification, as well as the control group (CG). Thus, the primary aim of the RETRAGAM study is to examine the effectiveness of a school-based RT intervention on MF, body composition, motivation, and enjoyment in children aged 10 to 12 years. Additionally, the study will compare the effects on the main outcomes among several intervention groups (i.e., RT, RT with gamification approach and the CG).
