ABSTRACT
Futsal is an intermittent high-intensity activity that places important demands on the aerobic and anaerobic pathways (Castagna et al., 2007). As consequence of this aerobic load, endurance has been reported to affect game performance (Barbero Alvarez et al., 2004; Castagna et al., 2007). Recently, Barbero Alverez et al. (2005) developed an intermittent high-intensity field test based match-analyses of futsal (FIET) to assess specific endurance. This new test demands that players perform shuttle running bouts (3×15 m) at progressive speeds interspersed with passive rest of 10-30 s until exhaustion. Despite the growing popularity of this test, no research has addressed the criterion validity and physiological demands of FIET. Therefore, the aims of this study were to examine the physiological demands and criterion validity of FIET.
