The purpose of this study was to determine the relationship between competitive trait anxiety measures and powerlifting (PL) performance. Thirty-six collegiate powerlifters on club teams from three universities were recruited during a competition (Male = 26, Female =10; Age 19.9 +/- 1.5yrs; Height 172.5+/- 8.6cm; Weight 81.4+/- 21.0kg). The athletes were distributed across weight classes for collegiate PL (47.6kg: 1; 51.7kg: 1; 54.9kg: 1; 59.8kg: 3; 67.1kg: 2; 74.8kg: 7; 82.1kg: 4; 89.8kg: 9; 99.8kg: 5; SHW: 3). A survey containing questions about powerlifting performance history and the 15-item Sport Competition Anxiety Test (SCAT) were administered to the participants prior to competing. The SCAT total was negatively correlated (r = -.397, p = 0.02) to the athletes' percentage of best total achieved in the competition (Actual Performance Total/Best Comp Total *100). Of the individual lifts, the SCAT score was negatively correlated to the personal best for bench press (r = -0.368, p = 0.03) and deadlift (r = -.317, p = 0.05), but did not significantly correlate for squat (r = -0.182, p = 0.27). These results indicate a negative correlation between SCAT score and athletes' personal best total in PL. Increased SCAT scores were associated with decreased personal best PL totals. The results suggest competitive trait anxiety may have negatively impacted performance and suggests some PL athletes may benefit from interventions aimed at decreasing anxiety prior to and during performance.
