Maximal strength testing, or one repetition maximum (1RM) testing, is safe and effective for children. This study found no injuries in healthy children aged 6.2 to 12.3 years undergoing 1RM strength tests.

Area of Science:

  • Pediatric Exercise Science
  • Sports Medicine
  • Child Health & Fitness

Background:

  • Strength training is increasingly accepted for pediatric conditioning.
  • Concerns exist regarding the safety and appropriateness of maximal strength testing in children.
  • Evaluating the risks associated with maximal strength testing in pediatric populations is crucial.

Purpose of the Study:

  • To assess the safety and efficacy of one repetition maximum (1RM) strength testing in healthy children.
  • To determine if maximal strength testing poses risks to pediatric subjects.
  • To provide evidence-based guidelines for pediatric strength testing.

Main Methods:

  • Recruited 96 healthy children (32 girls, 64 boys) aged 6.2–12.3 years.
  • Screened participants for medical conditions contraindicating maximal exertion.

  • Administered 1RM tests on upper-body and lower-body exercises using child-sized equipment under professional supervision.

    • Main Results:

    • No injuries were reported during the 1RM testing protocol.
    • The testing procedure was well-tolerated by all child participants.
    • No significant gender-based differences in strength test performance were observed.

    Conclusions:

    • One repetition maximum (1RM) strength testing is a safe and effective method for assessing strength in healthy children.
    • Appropriate supervision and procedures are essential for ensuring safety during pediatric strength testing.
    • Findings support the integration of 1RM testing into pediatric fitness assessments.
