Impact of resistance training on untrained adolescence and children upper body strength : a meta-analysis

Abstract EN

The purpose of this meta-analysis is to indicate the effect of resistance training protocols regarding duration and frequency on specific upper body strength, on children and adolescents.

Studies investigating the effects of resistance training programs and used the bench press test as an assessment of upper body strength were analyzed.

Twenty-three effect sizes were calculated in sub-groups by gender, age group (adolescents 11 to 15, childhood 8 to 10 years old), and training protocol (duration, frequency).

A total of 691 participants were included in the analysis.

This meta-analysis showed that females’ upper body strength is significantly affected more than males by the resistance training program.

Also, the results demonstrate that two training sessions per week are the most efficient method of strength gaining in the tested population.

Indicative of the importance of resistance training earlier in the lifespan to assess motor development and enhance injury prevention especially in females.
