description: Hypotheses No hypotheses will be posited. This study is descriptive, exploratory and estimation-based. Study Type This will be a survey study. Participants will answer a series of questions surrounding their ROM practices during resistance training for muscle hypertrophy/strength. Blinding Given this is a survey study, there is no blinding. That said, no information was given regarding the current state of evidence (e.g. full ROM being better or worse than partial ROM for muscle hypertrophy) to avoid any bias in responses. Study design This study will be a part of Milo Wolf's PhD thesis on the broader topic of range of motion within resistance training as it relates to muscle growth/strength. As many participants as possible will be recruited; the only inclusion criteria is that participants are training to maintain/increase muscle mass and/or strength. This survey will be online for at least a few months to maximise sample size. Once data analysis needs to begin (for the sake of completing the candidate's PhD). The questionnaire involved logic to ensure only relevant questions were shown to respondents and was constructed using Typeform.com. The full questions can be viewed below; the format of the questions included likert scales, yes/no questions, multiple choice questions, etc.. Full details are available below. Statistical Analysis Statistical analysis will be composed of: descriptive statistics (e.g. mean/standard deviations), exploratory sub-group analyses (e.g. based on education level) and thematic analysis for longer-form text-input style questions. Recruitment of participants Participants will be recruited via word of mouth and social media. Specifically, this study will be shared via social media channels/platforms and other researchers, users, etc. will be asked to spread the word. Sampling Plan Existing Data No existing data. Explanation of existing data No existing data. Sample size rationale See above. Stopping rule Not applicable. Variables Manipulated variables None. Transformations N/A Inference criteria N/A Data exclusion N/A Missing data When a survey is not fully completed, existing data from completed individual questions may still be used. Exploratory analysis All analysis will be considered exploratory given the lack of any qualitative evidence on the subject.
