Table 1_Real-time changes in player-perceived psychological momentum across scoring runs in volleyball: a single-match case study.docx

This single-match case study examined changes in male high school volleyball players’ perceived PM across scoring runs and whether these patterns differed between two teams.</p>Methods<p>Seventeen players (Team A, n = 8; Team B, n = 9) participated in a research-organized intra-squad match.

After each rally, players verbally rated their own team's PM on a 7-point scale. Immediate within-player PM changes following the first, second, and third points of scoring runs were analyzed using a cross-classified linear mixed-effects model with participant and team-by-rally event as random effects. An AR(1) sensitivity analysis and an exploratory analysis of cumulative PM change were also conducted.</p>Results<p>In the primary analysis, Team, Run position, and their interaction were not significant, and no between-team differences were observed at any run position.
