In study 1, fourteen rugby matches at the top level in domestic university teams were analyzed to verify the importance of kick-off play in the game of rugby football. Main results were as follows: 1) The number of kick-off plays averaged about 13 per match. 2) The average percentage of gaining balls were very low at the kicking side in kick-off play. 3) Whether the ball could be gained in kick-off play related significantly to the length of time the kicking side occupied the opponent ground after kicking off, and it related significantly to the rate of the kicking side's getting score and score chance. From these results, kick-off play was concluded to be an important set play in the game of rugby football at the level concerned.
