Table 1. Performance indicators and physiological responses in the MST (20 m multistage shuttle run test) and YIET (Yo-Yo intermittent endurance Level 2 test) in soccer players (n = 21). Data are means (±SD).
MST YIET
Distance covered (m) 2041 (179)* 1676 (314)
Peak speed attained (km·h-1) 13.6 (0.4)* 15.7 (0.8)

Post-exercise [La] (mMol) 13.0 (1.6) 13.1 (2.7)
Time to exhaustion in the test (min) 11.2 (0.8) 10.2 (2.7)
* significantly different from YIET, p < 0.001. Abbreviations: HR = maximal heart rate; [La] = blood lactate concentration.
