Volleyball Team Performance in Practice and Competition
(Omaha, Nebraska, USA)
How to improve volleyball team performance in competition? My volleyball team does really good during drills and practice, but during competition it seems we forget everything. How can we remember the right skills we learned in competition as well as practice?

Answer for Volleyball Team Performance in Practice and Competition:
This could be answered from several points of views. I am not going to talk about sports psychology. I approach this question from the skills and learning perspective.
Generally used metaphor in sports training is “skills go into the muscle memory”. That muscle memory contains hundreds or thousands different motor skills, which an athlete learns when practicing.
Athletes improve the specific skill (or motor skill) by repeating it over and over again. If the athlete is not consistent enough, s/he will eventually learn to be more consistent through repetitions. Some athletes will learn faster than the other ones.
Therefore the tip #1 is: give athletes as many repetitions as possible.
Tip #2: players need to perform those repetitions just like in the match, e.g. hitter needs to swing against the block and defense. When players practice hitting e.g. by coach tossing the ball or they do it without a block, the set up is quite different than in the match.
This is very important!
Tip #3: Players need to focus 100% when they are working on the skill. It helps players to put the skill in their "muscle memory".
When players focus on the technique when repeating it, it will help them to start “seeing a moving picture” in their minds how to perform the drill (read more: cognitive learning). If they just keep repeating the skill without really having their thoughts in it, it is difficult to see this correct image in their minds.
Moreover don’t let players lose their focus and get on the mindless repetition mode. If the drill is a longer one, keep changing it constantly, so the players stay alert. Communicate actively and constantly remind players to re-focus.
However, things are not that simple. There are other variables, like ability to play under pressure among other things, which may affect the performance in the match. Players learn to compete and handle the pressure by putting them in the pressure situations.
The tip #4: Play more and more matches.
Tip #5: Make players compete in practice. Using scoring and making players compete against each other in practice drills helps them to handle the pressure in the matches.

How are volleyball and physics related?
Serving: When a volleyball is served, the server exerts an upward, and forward, force on the ball. Meanwhile, gravity is exerting a downward force on the volleyball. This downward force is what causes the ball to fall down on the opponent's side, after clearing the net. To assist gravity, you can snap your wrist which adds top spin the skids over the ball as you serve. This spin crates pressure difference above and below the ball. According to researcher Dr. Marion Alexander, this top spin causes the ball to fall quickly on the opponent's side after clearing the net.
Passing: When a player performs a forearm pass, or bump, an upward and forward force is exerted on the ball toward a target player. Gravity exerts a downward force on the ball, and if you do not compensate for this, your target player will not have time to set underneath the ball before it hits the ground. To account for the force of gravity, simply follow through with your forearm when bumping, to exert force on the ball, over a longer period of time. This will cause the ball to go higher and ensure that the target player has time to prepare herself beneath the ball.
Spiking: When you spike a volleyball, you have the opportunity to deliver a crushing offensive blow to your opponent. When spiking, you exert a downward force on the ball so that it falls rapidly on the opponent's side of the court, making it very difficult for your opponent to return the ball. Gravity works in your favor when you spike, because it also exerts a downward force that makes the ball fall to the court floor. For this reason you do not necessarily have to exert tremendous downward force to spike effectively, because gravitational force is also acting on the ball in the same direction.
Digging: When digging a volleyball, you are exerting a sharply upward force to prevent it from hitting the ground. However, gravity is exerting a downward force on the ball, and if you do not account for this you will not hit the ball high enough to prevent it from hitting the ground. To account for this, bend your knees low to generate force with your legs, when digging. This will ensure that you hit the ball high enough for your teammates to get in position.
Work, velocity, and acceleration
Velocity: Velocity is the speed of movement. You can figure out the velocity of a volleyball shot by dividing the distance your ball traveled by the amount of time it took to get there. So let's say you serve a ball across the net from the behind the serving line, 30 feet, and the ball takes 1.5 seconds to get across the net. To find the velocity you would divide 30 feet by 1.5 seconds, which would be 20 fps. So the speed of movement, or velocity, of your serve was 20 feet per second. The higher the velocity the tougher it is for your opponent to hit the ball back to you. Which means, the faster your ball is traveling the harder it is to return.
Acceleration: Acceleration is an increase in velocity. Let's say you've just served the ball, it's gone over the net, and is falling to the ground. As gravity pulls the ball to the ground, it accelerates. If you gently lob the ball over the net and your opponent sends a hard spike back at you, that's another example of acceleration. The ball's velocity increased when spiked back over the net, by your opponent, therefore it accelerated.
Newton's three laws of motion
Newton's first law states that, " An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force."
How does this affect Volleyball? : Newton's first law of motion affects every volleyball player who botches a serve and sends the ball snacking into the net. Every player who blocks a hard-hit ball from an opposing player feels the law's effect on her stinging arms. The server's hand, the net, and the blocker's forearms acted as an unbalanced force that stopped, or changed, the direction of the ball, the object in motion.
Newton's second law states that, " The acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object."
How does this relate to Volleyball? : Newton's second law of motion is a mathematical equation that explains the relationship between force, mass, and acceleration. Mass multiplied by acceleration equals net external force. A spiked volleyball creates a net external force that stings your hands when you stop it. But your hands hurt even more when you stop a ball hit by a different, stronger opponent. The harder-hit ball's higher acceleration rate results in a stronger net external force.
Newton's third law states that, " To every action there is an equal and opposite reaction."
How does this relate to Volleyball? : Newton's third law explains that every action creates a force that is met by an equal reaction force from the opposite direction. When two objects interact, they exert a force on each other. The action force of a spiked ball meets the reaction force of a player's block. A team scores a point when the action force of a spiked ball meets the reaction force of the opposing team's court. The hard floor has more force than the soft ball, so the ball bounces off the court to equalize the reaction of the impact.
