Preferred reporting items for resistance exercise studies (PRIRES) explanation and elaboration

Resistance training significantly benefits both the general population's health and athletes' muscular strength and power, with outcomes influenced by various factors such as exercise intensity and movement velocity. Comprehensive reporting is crucial for enabling study comparisons and translating scientific findings to practice. The Preferred Reporting Items for Resistance Exercise Studies (PRIRES) checklist, designed to enhance clarity, transparency, and reproducibility in resistance exercise research, was developed through an umbrella review of systematic reviews specifically targeting studies on resistance exercise training. PRIRES comprises 26 reporting items (39 subitems) covering exercise selection, training program and progression/regression, exercise setting, and planned versus actual training. This explanation and elaboration document aims to improve the understanding and implementation of the PRIRES checklist by providing the rationale for each reporting item, along with illustrative examples drawn from prior primary studies. In conclusion, this project aspires to serve as a meaningful and readily applicable checklist for experts in resistance exercise training literature. Improved understanding of these reporting items among researchers from diverse fields is expected to foster the adoption of thorough reporting practices.
