Fitness Field Tests Correlate to Game Performance in U-19-Category Basketball Referees.

To examine the relation between game-performance, physiological responses and field-test results in Tunisian basketball referees. computerized time-motion analysis, heart rate (HR) and blood lactate concentration [La-] were measured in 15 referees during 8 competitive games (under-19 years-old Tunisian league). Referees also performed: repeated sprint test (RSA), Yo-Yo Intermittent Recovery Test level 1 (Yoyo-IRT1), T-test, 30-m sprint with 10m lap-time. Computerized video analysis determined the time spent in 5 locomotors activities (standing, walking, jogging, running and sprint), then grouped in high, moderate and low-intensity activities (HIA, MIA and LIA, respectively). Yoyo-IRT1 performance correlated with: 1) total distance covered during the fourth quarter (Q4, r=0.52, p=0.04), 2) distance covered in LIA during all game periods (p<0.05). Both distance covered and time spent in MIA during the Q1 were negatively correlated with the Yoyo-IRT1 performance (r=-0.53, p=0.035; r=-0.67, p=0.004, respectively). A negative correlation was found between distance covered at HIA during the 2nd half (Q3+Q4) and fatigue index of the RSA test (r=-0.54, p=0.029). Mean HR (expressed as %HRpeak) during all game periods was correlated with Yoyo-IRT1 performance (0.61≤ r <0.67, p<0.01). This study showed that: 1) the Yoyo-IRT1 performance is a moderate predictor of game physical performance in U-19 basketball referees and 2) referees' RSA correlates with the amount of HIA performed during the 2nd half time, which represents the ability to keep up with play.
