Reliability and validity of a novel futsal special performance test designed to measure skills and anaerobic performance

Purpose: This study examined the validity and reliability of a novel futsal special performance test (FSPT) as a measure of futsal performance and skills. Methods: Thirty six futsal players with different levels of experience were recruited and divided into two groups (elite and non-elite). Players participated in four sessions (at least 7 days apart); a) familiarization session, b) anaerobic power (Wingate test), c) FSPT trial 1, and d) FSPT trial 2. The FSPT was carried out on a futsal court (wooden sprung floor) and examined skills such as dribbling, rotation, long and short passing and shooting. Content validity was assessed using 6 experienced futsal coaches and instructors. Results: There was a significant correlation between FSPT and various aspects of anaerobic power (r=0.5 to 0.91, p≤0.001). Moreover, significant large correlations were observed between test and re-test of FSPT (r= 0.77; 95% confidence intervals (CI)= 0.56 to 0.98; p≤0.001). All instructors and coaches confirmed the content validity. There was high inter-rater reliability of the FSPT (r=0.89; 95% CI= 0.85 to 0.93; p<0.001). FSPT total (p=0.001), penalty (p=0.022) and performance (p=0.001) time was superior in elite relative to non-elite players. Anaerobic power was greater in elite players (p<0.001). Conclusion: Our results support the use of the FSPT to assess futsal players’ performance in conjunction with skill and anaerobic fitness.
