Sports Medicine: Just the Facts

(やまだぃちぅ) #1

HISTORY



  • Rugby is a cross between soccer and football. (Dietzen
    and Topping, 1999)
    •Invented in 1932 when William Webb Ellis picked up
    the ball and advanced it in a soccer match at Rugby
    College in England. The only way to stop the runner
    was to tackle him or her. (Dietzen and Topping, 1999)

  • American football evolved from rugby in the late
    nineteenth century.

  • It was an Olympic sport from 1900 to 1924. (USA
    Rugby website)

    1. The United States won the gold medal in 1920 and
      1924.



  • After 1924, it was no longer an Olympic sport, and
    this was followed by decreased popularity in the
    United States. (USA Rugby website)

  • It is currently being considered for reinstatement as an
    Olympic sport for the 2012 games. (USA Rugby web-
    site)


MATCH



  • Goals(USA Rugby Football Union, 2003)

    1. Where as American football is a game of yardage,
      rugby union is a game of possession.

    2. The player with possession of the ball is the front-
      most player on the attacking team. He or she may
      advance the ball by running with the ball, kicking
      it forward, or by passing it backward or laterally to
      another player on his or her team.
      a. All teammates are behind the ball carrier in sup-
      port.
      b.Unlike American football, blocking for the ball
      carrier is not permitted and is penalized as
      obstruction.

    3. The objective is to maintain control of the ball and
      touch it down in the try zone (the rugby equivalent
      of the American football end zone).
      a. Once crossing the try line, the player must touch
      the ball down on the ground in order to register
      a try, which is worth 5 points.
      b.The try entitles the scoring team to attempt to
      kick the ball through the goal posts, which is
      worth another 2 points.
      i. The kicker takes the ball out of the try zone
      along a line where the ball was touched down
      parallel to the touch lines.

    4. An offensive player may also attempt to drop-kick
      the ball through the goal posts during open play,
      which is worth 3 points.

    5. The team with the maximum points at the end of
      the match is the victor.
      6. A typical game requires the athlete to cover a dis-
      tance of 5 to 8 km, running at speeds up to 5–8 m/s
      (comparable to soccer) (Dexter, 2003).
      7. In addition, the rugby player is involved in >1–2
      episodes of collision contact per minute (Dexter,
      2003).
      a. These equate to approximately 40 tackles and
      up to 70 rucks and mauls per game.
      b.The forwards sustain an additional 30 scrums
      and 40 line outs per game.
      8. There are few substitutions allowed. The mean
      duration of high intensity work (sprinting or con-
      tact) is 38 s/min with an average workload of 51
      min per 80-min match. In comparison, the average
      American football game has only 10 min of con-
      tact or significant exertion per game (Dexter,
      2003).



  • Pitch:The rugby field is called the pitch (USA Rugby
    Football Union, 2003).



  1. The rectangular field of play (which excludes the
    goal zones) does not exceed 70 m in width and
    100 m in length.

  2. Each try zone is the same width as the remainder
    of the pitch and is between 10 and 22 m in depth.

  3. The pitch has the following solid lines:
    a. Half-way line or midfield line (half the distance
    between the try lines)
    b.Ten-meter lines on each side of the half way line
    c. Twenty-meter lines (22 m from the try lines)
    d. Try lines
    e. Dead ball lines (at the deepest portion of the try
    zone)
    f. Touch lines (side lines)

  4. Dashed lines
    a. Positioned 5 and 15 m parallel to the touch
    lines.

  5. The goal posts are on the goal line and are in the
    field of play.
    a. The distance between the posts is 5.6 m in width
    with a minimum height of 3.4 m.
    b.The crossbar is 3.0 m from the ground.
    c. The posts should be padded (since players can
    collide with them as they are in the field of play)



  • Rules



  1. The match is divided into two 40-min halves with
    a 5–10-min half time (USA Rugby Football Union,
    2003).

  2. A player who leaves the match and is substituted
    may not return to the match.
    a. Exception: A player maybe substituted for a
    maximum of 15 min for control of bleeding
    from an injury. After bleeding is controlled, he
    or she may then return to play. This is com-
    monly referred to as a blood sub.
