| Resumo | |
This study aimed to evaluate absolute and relative (%(V) over dotO(2max)) oxygen uptake (total,. during effort and pause), and time spent above 90% of (V) over dotO(2max) during high-intensity intermittent running in subjects with different training status. Fourteen males were evaluated and divided (moderate and high aerobic power) according to their (V) over dotO(2max) obtained in an incremental treadmill test to volitional exhaustion. They were then submitted to high-intensity intermittent aerobic exercise (1 min:1 min at maximum velocity attained during the treadmill test, totalling 4 km). A Student's t test for independent data was conducted to identify differences between groups. The moderate aerobic power group spent more time above 90% (V) over dotO(2max) compared to the high aerobic power group (30.2 +/- 9.1%; 7.3 +/- 6%, respectively, P=0.001). Moreover, the moderate aerobic power group presented lower (V) over dotO(2)total (P=0.011), (V) over dotO(2)effort (P=0.007), higher (V) over dotO(2)total (%(V) over dotO(2)), (V) over dotO(2)effort (P<0.001), (V) over dotO(2)pause ((V) over dotO(2max) %) (P=0.006) compared with the high aerobic power group. There was no difference in (V) over dotO(2)pause between groups (P=0.091), the difference between (V) over dotO(2) effort and pause was greater for the high aerobic power group compared with the moderate group (4.4 +/- 2.1;. 7.8 +/- 2 mL-kg(-1)min(-1); P=0:009) and the difference between (V) over dotO(2) effort and pause (%(V) over dotO(2max)) was not different between groups. To conclude, these results demonstrated that individuals with better aerobic fitness spent less time above 90% of the (V) over dotO(2max) and that this response can be due to better capacity to recover during the pause.
