Purpose: To investigate sports coaches' Twitter use. Methods: Coaches (N = 310) from 22 countries and a range of sports completed an online survey. Quantitative survey data were analyzed descriptively and triangulated with qualitative data using Leximancer (Brisbane, Queensland, Australia) text mining software. Results: Most participants reported using Twitter for [greater than or equal to]3 years and accessed the platform multiple times per day. More than half participants agreed that using Twitter had positively impacted both their own confidence as a coach and their athletes/players/team's performance. The strongest overall themes from the qualitative data revealed that Twitter helped sports coaches improve their practices through the sharing of information, connecting with other coaches, and building positivity into their interactions when supporting players. Discussion/Conclusion: Sports coaches perceive Twitter to be a highly valuable platform to network, collaborate, gain access to information, and share ideas and resources.
