Aerobic power and jumps predict performance in intermittent running test in young indoor soccer players

Abstract

Indoor soccer is an intermittent modality, which requires high-intensity efforts of different demands such as aerobic and muscle power. Thus, the search for improvement of these requirements from mutual relations may be a relevant tool for the sport. This study attempted to correlate and calculate predictive equations for different physical fitness variables in intermittent effort protocols. Eighteen indoor soccer players (15 ± 1.3 years, 75.4 ± 20.2 kg, 167 ± 0.8 cm) were assessed for their ability to repeat sprints (from the Forward-Backward test), maximal aerobic power (MAP with the Yo-Yo Intermittent Recovery Test) and power of the lower limbs (triple horizontal jump, THJ). Pearson’s test was used for correlations and the stepwise method for linear regressions. In addition to different significant correlation, considering performance at THJ and MAP, determination values of 44% to 64% for the capacity of repeating sprints were observed. In this context, THJ and MAP can predict the time spent in different series of repeated efforts (p?0,02) and minimum, average and maximum power (p <0.05). It was concluded that MAP and performance in THJ can determine and even predict the ability to repeat sprints.
