Validity of simple field tests as indicators of match-related physical performance in top-level professional soccer players.

摘要: The aim of this study was to examine the construct validity selected field tests as indicators match-related physical performance. During competitive season, eighteen professional soccer players (age 26.2 +/- 4.5 yrs, mass 80.8 7.8 kg, and height 181.9 3.7 cm) completed an incremental running test exhaustion, a vertical-jump repeated-sprint ability (RSA) test. Match performance quantified during official matches using video-computerized, semi-automatic, match analysis image recognition system, (ProZone, Leeds, UK). measures were: total distance covered (TD), high intensity (HIR: > 14.4 km . h (-1)), very (VHIR:> 19.8 sprinting (> 25.2 (-1)) top speed. Significant correlations were found between peak speed reached TD (r = 0.58, R (2) 0.34; p < 0.05), HIR 0.65, 0.42; 0.01) VHIR 0.64, 0.41; 0.01). also RSA mean time - 0.60, 0.36; differences best worst group defined by median split technique for (TD 12 011 747 m vs. 10 712 669, 3192 482 2314 347 m, 1014 120 779 122 respectively; 0.05) (VHIR 974 162 819 144 235 56 164 58 0.05). In conclusion, gives empirical support in top-level players.
