BACKGROUND: Soccer is an intermittent team sport that demands high aerobic capacity. On field, soccer players' aerobic capacity, assessed through the maximal oxygen uptake (VO<inf>2</inf>max), is usually determined by an intermittent recovery test. The aim of this study was to obtain a construct validity of a new intermittent recovery test (IRT) with a fixed speed and a progressive decrement of rest period.
METHODS: Twenty-five male soccer players were recruited to perform an incremental continuous test (ICT) and the new IRT, to compare their physiological data. Fifteen male soccer players were involved to perform a test-retest of IRT to assess its reliability.
RESULTS: VE<inf>peak</inf>, absolute VO<inf>2</inf>max, relative VO<inf>2</inf>max and VCO<inf>2</inf>peak registered during ICT and IRT correlated strongly (Pearson's correlation coefficient ranges from 0.75 to 0.80, with very large as magnitude of effects and with P<0.001). IRT showed reliability from good to excellent regarding VE<inf>peak</inf>, absolute VO<inf>2</inf>max, relative VO<inf>2</inf>max, VCO<inf>2</inf>peak and covered distance (ICC values ranged from 0.82 to 0.95).
CONCLUSIONS: These findings and its underlying physiological and muscular demands, suggest that IRT can be considered as a valid and reliable test to assess aerobic capacity in soccer players during the competitive period.
