This study targeted a basketball game and focused on the games in which a team blew the lead and lost the game though it had widened the gap and had taken a big lead at some point during the game. The purpose of the study was to analyze the following matters and to review how a team blew the lead and lost the game. The matters were as follows: ① How many points could be turned around? ② How often did such a game occur? ③ If a team took a big lead, how was the subsequent intermediate step of the game? The surveyed games were 336 in total in the Kanto Female Students Basketball Tournament (First division) during 6 years from 2001 to 2006. According to the survey results, there were multiple games in which a team blew the lead and lost the game though it had a maximum lead of 20 points at the close of the second period and a maximum lead of 15 points at the close of the third period. In 30 games, a team took a lead by 16 to 20 points at the close of the second period. Of these games, a team won subsequently in 27 games and a team blew the lead and lost the game in 3 games. The analysis of an average point scored and lost of the team having a lead showed that the team had gained fewer points and had given more points away in the third period rather than in the second period on a statistically-significant level. According to these analyses, it became clear that the team taking a big lead at the close of the former part of the game (the second period) had not been able to gain more points and overpower the opposing team as energetically as ever in the third period just after widening the gap, aside from the result whether it had finally won or lost the game. And this was considered to be one of the causes for a team to blow the big lead and lose the game.
