Effects of fatigue and time-out on physiological, time-motion indicators and in patterns of spatial organization of the teams in basketball

摘要

The aim of this study was to identify the effects of fatigue on physiological variables, time-motion indicators and patterns of spatial organization of the teams in basketball. The study sample consisted of 10 basketball players of the under-18 with a mean age of 17.5 ± 0.3 years. There were two sessions: session a) game continuous (C1) 10 minutes - yo-yo intermittent recovery test (level 1) - 1 minute timeout – game continuous (C2) 10 minutes. Session b) game interrupted (I1) 5 minutes - 1 minute timeout - 5 minutes game - yo-yo intermittent recovery test (level 1) –1 minute timeout -game interrupted (I2) - 5 minutes - 1 minute timeout - 5 minutes game. HR values were determinate by the YYIRTL1 and registered by short range radiotelemetry heart-rate monitors (Polar Team System, Polar Electro, Finland), time-motion analysis were registered with GPS (SPI Elite. GPSports Systems, Australia), and a digital camera was used to record the game. The results suggest that the fatigue and the time-outs promote betters patterns of spatial organization. Additionally the results showed that with the accumulated fatigue the players covered a less total distance and in a slower way.
