Principles & Concepts Of Physical Activity.
There are many concepts of physical activity used in every day exercises and activities. The sport of basketball is an excellent one, there are so many different techniques to improve upon. In this essay I will present the different concepts used in this sport in certain situations, in particular catching a basketball and shooting it. There are very few times in basketball that the player catches the ball completely stationary so I am going to examine the concepts bringing the participant from a run, coming to a sudden stop, receiving the pass and get into a shooting position. .
Moving toward the ball is an excellent way to receive a pass, proceeding in a straight line to the player with the ball decreases the amount of time the ball is unprotected. By closing the distance in between the two players the pass becomes much more effective and accurate. Running in a straight line would describe linear motion as well as angular motion by moving around a center point such as the knee. As the player nears the point of contact with the ball momentum will change. Slowing down to catch the ball, which increases friction on the shoe from the floor slows the player down to a stop where he/she can prepare to catch the ball. Stopping with bent knees absorbs some of the force by increasing the amount of time and distance the force is absorbed, it allows for a more stable surface and or the ability to change direction to move to a more open area. Still keeping both eyes on the ball the player widens his/her stance, increasing the base of support, and angular bending of the knees, to lower the center of gravity. Now stable, but still with eyes on the ball, the player extends his/her hands in the direction of the traveling ball. By extending the hands the player increases the amount of time it takes for the ball to come into contact with his body.
