アルティメット公式ルール

5. チーム編成

1. 5.1. 各チームは、5～7 人の選手がフィールドにいる状態で試合をおこなう。
   解釈： Mixed games

   In Mixed games, where men and women play on the same team, both teams should have the same gender ratio as each other on the field for each point. Events should use one of the options in the WFDF Rules of Ultimate Appendix to determine the gender ratio for each point.

   Steinarのコメント（非公式！）： Gender designations

   Gender is a very sensitive and complicated topic. Generally, the rules no longer require players to identify as male or female to play ultimate. Instead, the terms “male-matching player” (MMP) or “female-matching player” (FMP) are used, which allows e.g. non-binary players to say “physiologically, it is most fair that I match up with males when playing” instead of having to declare an untrue gender identity.

   See also the WFDF Transgender Policy, WFDF Policy on Non-Discrimination and WFDF Safe Sport Policy.

2. 5.2. 各チームは、チームを代表するキャプテン及びスピリットキャプテンを指名しなければならない。
   解釈： Role of captain and spirit captain

   The team captain is a team member, who is eligible to participate in the game, and has been designated to represent the team in decision-making on behalf of the team before, during, and after a game.

   The spirit captain is a team member, who is eligible to participate in the game, and has been designated to address, discuss, and resolve spirit issues at any point throughout the competition with opponents, teammates, coaches, and game or event officials.

3. 5.3. 各チームは、得点後から次のプルの準備完了の合図までの間、人数制限なしで選手を交代することができる。

   Steinarのコメント（非公式！）： ABBA system

   In mixed games, the ABBA system is now nearly ubiquitous; start with some ratio (A), then play two points of the opposite ratio (BB), two points of the original ratio (AA), and so on. This is defined as Ratio Rule A in the appendix. Usually, the dominant gender on the field also now pulls (“WFDF pull rule”, A6.2.2 in the appendix)).

   Some tournaments may play “loose mixed”, where the ratio need not be 4–3, but could be e.g. “at least two of each gender” with the ABBA pattern only determining the pulling gender. There will be local variations here; note that WFDF has pointed out that the rule is written very carefully to say “should” and not “must”.
