This study evaluated the effect of game venue and starting status on pre-competitive psychophysiological measures in elite rugby union. Saliva samples were taken from players (starting XV, n = 15 + non-starters; n = 9) on a control day and 90 min prior to 4 games played consecutively at home and away venues against local rivals (LR) and league-leaders (LL). Pre-competition psychological states were assessed using the Competitive State Anxiety Inventory-2. The squad recorded two wins (home) and two losses (away) over the study period. Calculated effect sizes (ES) showed higher pregame cortisol (C) and testosterone (T) difference values before all games compared to a baseline control day (ES: 0.7 to 1.5). Similar findings were observed for cognitive and somatic anxiety. Small between venue C differences were observed in starting XV players (ES: 0.2 to 0.25). Conversely, lower ‘home’ T (ES: 0.95) and higher ‘away’ C (ES: 0.6) difference values were observed in non-starters. Lower T difference values were apparent in non-starters (vs. starting XV) before ‘home’ games providing evidence of a between group effect (ES: 0.92). Findings show an anticipatory rise in psychophysiological variables prior to competition. Knowledge of starting-status appears a moderating factor in the magnitude of player endocrine response between home and away game venues.
