The following were found through the meta-analytic method. Regardless of age, children generally appear capable of eliciting an improvement in muscular strength and muscular endurance. Resistance training effects can be found in young, adult, and aged populations.
Girls have the potential to improve more than boys.
Resistance training is effective regardless of the body segment under investigation. These findings are based on less than extensive data for children. Particular questions and specific populations need to be investigated by appropriate research. Resistance training improves the performance of children in resistance exercises. It has yet to be demonstrated that such improvements are due to real morphological adaptations or whether they are purely neurologically determined, that is, they are learned skills.
