  • If a kicker leans too far back during the kick, where does the centre of gravity move?
    It moves backward, which may cause loss of power and poor accuracy.
  • What is the base of support in a rugby goal kick?
    t’s the area between and under the feet of the kicker, especially the planted foot during the kick.
  • What would happen if the kicker had a narrow base of support?
    The player would be less stable, making it harder to control the kick and maintain balance.
  • What coaching tip could improve stability in young goal kickers?
    Encourage a strong, wide base of support and a slight forward lean to keep the COG in line.
  • What is the line of gravity in biomechanics?
    It’s an imaginary vertical line that passes through the center of gravity to the ground.
  • How does the centre of gravity shift during a goal kick?
    It moves from a stable position over the base to a forward position as the kick is executed.
  • What phase of the goal kick requires the most stability?
    The preparation and planting phase, when the kicker lines up and prepares to strike the ball.
  • When the line of gravity shifts outside the base of support during a kick, what can happen?
    The kicker may lose balance or fall over.
  • In the follow-through of a goal kick, why might the line of gravity shift forward?
    Because the body leans into the kick to generate power and momentum.
  • What is the centre of gravity?
    It’s the point where the body’s mass is equally balanced in all directions.
  • During the follow-through, why does the kicker temporarily become unbalanced?
    Because the line of gravity may fall outside the base of support due to the forward motion.
  • How does foot placement affect balance in a goal kick?
    Proper foot placement helps maintain balance and direct the force through the ball accurately.
  • How can a player lower their centre of gravity before a kick?
    By bending their knees slightly and keeping their torso over the planted foot.
  • How can a rugby player increase their base of support before a goal kick?
    By widening their stance or firmly planting their non-kicking foot on the ground.
  • What role do arms play in controlling balance during the kick?
    Arms help counterbalance the movement and maintain equilibrium during the motion.
  • How should the line of gravity be positioned during a goal kick?
    deally, it should fall within the base of support for balance, especially before the kick.
  • Why is a low centre of gravity useful in a goal kick?
    It increases balance and stability during the preparation phase of the kick.
  • Why is a stable base of support important for a goal kick?
    It provides balance and control during the kicking motion.
  • How do all three concepts—base of support, line of gravity, and centre of gravity—work together in a successful goal kick?
    Together, they ensure the kicker is balanced, powerful, and controlled before, during, and after the kick.
  • How does the body compensate when the line of gravity moves forward during a kick?
    The non-kicking foot and arms help maintain balance and control.
