“Choking under pressure” is a maladaptive response to performance pressure whereby choking models have been identified, yet, theory-matched interventions have not empirically tested. Thus, the purpose of this study was to investigate whether a preperformance routine (PPR) could reduce choking effects, based on the distraction model of choking. Three “choking-susceptible”, experienced participants were purposively sampled, from 88 participants, to complete ten-pin bowling deliveries in a single-case A1-B1-A2-B2 design (A phases = “low-pressure”; B phases = “high-pressure”), with an interview following the single-case design. Participants experienced “choking” in the B1 phase, which the interviews indicated was partially due to an increase in self-awareness (S-A). During the B2 phase, improved accuracy occurred when using the personalized PPR and, qualitatively, positive psychological outcomes included reduced S-A and decreased conscious processing. Using the personalized PPR produced adaptive and relevant, task-focused attention.

The purpose of this study was to examine the effectiveness of an imagery intervention for enhancing the experience of flow state and performance in junior athletes. On the basis of previous results, a tailored imagery script was developed to target critical flow dimensions, namely challenge-skills balance, clear goals, concentration on the task, and sense of control. It was hypothesized that the use of cognitive and motivational imagery would increase specific flow dimensions, which, in turn, would enhance flow state and competition performance. Participants in a single-case, multiple baseline A-B design study were four nationally ranked athletes. Following a 6-week baseline phase monitoring flow state and performance and a 6-week intervention phase using relaxation in conjunction with imagery techniques, three participants showed a sustained increase in flow experiences, and all four participants improved their service performance, groundstroke performance, and ranking-list position.

Purpose: To investigate the influence of recruitment age on retention and release across the development pathway and to explore the influence of anthropometric and physical characteristics on retention and release at different ages throughout the development pathway and the likelihood of obtaining a professional contract. Methods: Following receipt of ethics approval, a cross-sectional study tracking 4 cohorts of players over 5 years assessed 76 male youth football players (11–16 y) from an English football academy on 3 occasions annually in anthropometry, countermovement jump height, and linear (30 and 15 m) and multidirectional sprint time. Players were categorized based on their start and release date. Results: Starting early (ie, before U12) in an academy was a key indicator of obtaining a professional contract, representing 87% of the players signed. Bayesian regression models suggest that the majority of differences in physical characteristics between players that were released and retained are trivial, small, and/or uncertain. Players who attained a professional contract at 18 had slower 15- and 30-m sprint times at U13 to U15 (P > 0 = .87–.99), slower multidirectional sprint times at U14 (P > 0 = .99), and lower countermovement jump height at U13 to U16 (P > 0 = .88–.99) compared with players who did not gain a contract. Conclusion: Players recruited early have an increased likelihood of gaining a professional contract. Physical assessments lack utility when used in isolation as a talent-identification tool.
