Adverse effects of technical fouls in elite basketball performance

This study examined the temporal effects of technical fouls on the performance of the fouling and opposing teams in elite basketball games. A sample of 80 technical fouls was collected from 65 international games. The fouls were charged either to players on court or to the bench players/coaching staff. Performance measures considered were the points scored (during 1, 3, and 5 ball possessions), fouls received, violations, and turnovers during 5 ball possessions before and after a technical foul was called. Data were also obtained on several contextual variables. The results showed that the opposing team scored slightly more points compared to the fouling team during 1 ball possession before and after a foul was charged to the coach/bench personnel (F=5.934; p=0.019; ES=0.11). The results also showed that both types of technical fouls are generally positive for the opposing team (mid-term effects) and for the fouling team only during the short-term performance (points scored after 1 ball possession). Furthermore, significant differences between teams were found when comparing the fouls received, with the opposing team receiving more fouls after both types of technical fouls (F=5.364; p
