Figure skating jumps
Jumps are referred to by how many times the skater turns in the air. One revolution (one and a half for the Axel) is a "single" jump. Two revolutions (two and a half for the Axel) is a "double" jump. Three revolutions (three and a half for the Axel) is a "triple" jump. Four revolutions (four and a half for the Axel, although this has never been done in competition) is a "quadruple" or "quad" jump. The first triple jump landed in competition was a loop jump. It was landed by Dick Button in 1952. The first quadruple jump landed in competition was a toe loop jump. It was landed by Kurt Browning in 1988. Currently, men in world-class competition usually attempt a full set of triples and sometimes one or two quadruple jumps in their free skating programs. Triple Axels are rare for ladies, and quadruple jump attempts even more so.
Double (basketball)
A quadruple-double is defined as a performance in which a player accumulates a double digit number total in four of five statistical categories—points, rebounds, assists, steals and blocked shots—in a game. This feat is extremely rare: only four players have officially recorded a quadruple-double in National Basketball Association (NBA) history. The first American male player above the high school level to officially record a quadruple-double was Nate Thurmond, who achieved this feat in 1974 while playing for the NBA's Chicago Bulls. The first American female player above the high school level to officially record a quadruple-double was Ann Meyers, who achieved this feat in 1978 while playing for the UCLA Bruins, when women's college sports were under the auspices of the AIAW. The first male player in NCAA Division I history to record a quadruple-double was Lester Hudson in 2007. The first Division I women's player to have officially recorded a quadruple-double since the NCAA began sponsoring women's sports in 1981–82 was Veronica Pettry of Loyola–Chicago in 1989. Only three other women have done so since, and Shakyla Hill's quadruple-double for Grambling State in 2018 was the first since 1993. An earlier player, Jackie Spencer of Louisville, accomplished the feat against Cincinnati during the 1984–85 season, but the NCAA did not record assists and steals throughout Division I women's basketball at that time. The Metro Conference, then home to both schools, did officially record these statistics, but the NCAA did not start doing so until 1985–86 for assists and 1987–88 for steals.
