BACKGROUND: Despite the well-established benefits of resistance training (RT) in reducing health risks and enhancing quality of life, adherence to RT guidelines remains low. Promoting RT through healthcare practitioners could facilitate its widespread adoption. Although numerous studies have examined healthcare practitioners' knowledge and prescription practices of physical activity, few have specifically focused on RT. METHODS: Prescription practices and barriers, knowledge and attitudes toward RT, and attitudes toward RT education were assessed from a convenience sample recruited by a multichannel approach (eg, social media and mailing lists). Physicians answered an online questionnaire composed of 32 questions developed by a multidisciplinary team. A convenience sample was recruited through social media and mailing lists. RESULTS: A total of 158 family physicians practicing in Israel completed the questionnaire. RT prescription rates were low, ranging from 16.9% to 31.9%, depending on the estimation method. Self-reported barriers to RT prescription included insufficient knowledge about RT and how to prescribe it. Physicians showed limited knowledge of RT guidelines but generally viewed RT positively for various health conditions. Finally, 83.5% felt inadequately trained in RT, and 88.6% expressed a desire for further education. CONCLUSIONS: This study highlights a gap between the recognized benefits of RT and the prescription practices and knowledge of family physicians. Enhanced educational efforts targeting RT could bridge this gap, potentially increasing RT prescription rates and improving public health outcomes.
