Identified research gaps in the literature and recommendations for future studies.

Identified problems from scoping review	Implications for future research
Lack of studies that examined RT effects in child athletes	Particularly examine the effects of RT in child athletes
Lack of studies that reported measures of biological age	Always determine and report a measure of biological age (e.g., peak-height velocity)
Lack of studies that examined sex-specific effects of RT	Particularly examine the effects of RT in female youth athletes
Lack of studies that examined physiological adaptive processes following RT in child and adolescent athletes	Elucidate neuromuscular and tendomuscular mechanisms following RT in youth athletes according to sex and biological age
Insufficient reporting and inclusion of stress and strain-based parameters in RT studies	Describe RT protocols in more detail (report stress and strain-based parameters)
Insufficient matching of RT protocols when comparing different protocols	When comparing different RT protocols make sure that protocols are matched for strain-based parameters (e.g., time under tension) or mechanical work (i.e., lifted overall load)
