The purpose of this study was to examine the influence of different team formation methods on the physiological responses to and time motion characteristics of 4-a-side small-sided games (SSG4) in young soccer players. Thirty-two young soccer players (age 16.2±0.7 years; height 172.9±6.1cm; body mass 64.1±7.7 kg) voluntarily participated in this study. Anthropometric measurements, technical tests and maximum oxygen uptake (VO2max) tests were carried out on the players. SSG4 teams were then created using four different methods: according to the coaches' subjective evaluation (CE), technical scores (TS), VO2max (AP) and VO2max multiplied by technical scores (CG). The teams thus created played four bouts of SSG4 at two-day intervals. During the SSG4, Heart Rate (HR) responses, distance covered and time spent in HRmax zones were recorded. In addition, Rating of Perceived Exertion (RPE) and Blood Lactate Level (La) were determined at the end of the last bout of each SSG4. Percent of HRmax (%HRmax), La and RPE responses during SSG4 were significantly higher for teams chosen according to AP and CG compared to CE and TS (p<0.05). In addition, teams chosen by AP and CG spent significantly more time in Zone 4 (above 90 % HRmax ) and covered a greater distance in the high intensity running zone ( above 18 km.h ) than teams formed according to TS. Moreover, AP teams covered significantly greater total distance than TS teams (p<0.05). In conclusion, in order to spend more time in both the high intensity heart rate zone and the high intensity running zone, the teams in SSG4 should be formed according to the players' VO2max values or the values calculated using both the VO2max and technique scores.
