Reflect and evaluate your application of biophysical principles to learning physical skills
I have been learning to play volleyball for a term during two fifty-minute sessions per week. I have chosen to specifically focus on two skills that I have learnt – the dig and set. The biophysical principles that have contributed to learning, developing and improving these skills are force summation, balance and stability, stages of learning and feedback.
The biophysical principle that contributed the most to learning the dig skill was balance and stability. Balance and stability is the ability to maintain a position in space when disturbed by an unbalanced force. The four factors that determine increased balance and stability is a wider base of support …show more content…
A projectile is an object moving through the air only influenced by the downward force of gravity. The three factors that determine the flight path of a projectile is the angle, height and speed of release. If I was not balanced and stable due to a low centre of gravity during the execution stage of the set skill, I would not be able to get completely underneath the ball. Consequently, the ball would not be executed on my fingertips so the angle of release would be decreased. Therefore, the ball (projectile) would have unintentionally travelled downward, which is a disadvantage in a volleyball match. To improve my set skill, I should have flexed my knees so the ball could directly contact my fingertips. This would achieve the ideal flight path due to the increased the angle of release (e.g 70°) as the ball should travel high, not far. This gives another player the opportunity to spike the ball down over the net, which could result in gaining a point in a volleyball match. Therefore, applying the biophysical principle of projectile motion together with balance and stability is an advantage when learning, developing and improving the skill. However to achieve this high angle, the height of release has to be compromised, so the other player has less time to execute a powerful and effective
