Athletes’ practice environment can influence their competitive performance. The influencing performance factors present in practice are understudied, and the aim of this study was to explore these factors. Using a case-study approach, the authors investigated a basketball practice environment to reveal influencing performance factors. Participants were 15 members of a U.K. Elite Academy Basketball League team based in a sixth-form college (equivalent to American high school age) that included 10 players, 2 coaches, 1 strength and conditioning coach, 1 academic teacher, and the head of sport (mean age 21.8 yr). A case-study approach was adopted to collect data from interviews, focus groups, and direct observations to provide a holistic assessment of the practice environment. Data were analyzed using inductive thematic analysis, which revealed 6 overarching themes: effort, status, individuality, preparation, team drive, and practice vision. Data analysis exposed several themes of influencing performance factors unreported in previous literature, suggesting that practice environments should be viewed as a stand-alone field of investigative enquiry. The results from this study provide a much-needed foray into the psychological influences of practice and give practitioners the opportunity to reflect on the results against their own practice environments.
