Flight time was analyzed for six total serves, 3 jump serves and 3 standing overhand serves. Flight time was discovered using the running clock tool on Dartfish Analysis Software. Table 1 displays the summarized findings of flight time of 3 jumps serves and 3 standing overhand serves.
Table 1. Summarized findings of flight time for 3 jump serves and 3 standing overhand serves. Flight time was discovered experimentally through Dartfish Analysis Software.
Average flight time for the jump serve and the standing overhand serve was calculated, and summarized in Table 2.
Table 2. Average flight time of the jump serve and the standing overhand serve was calculated based on data from Table 1.
A sample calculation for average flight time is displayed below. Each calculation was performed identical to the sample.
Ball velocity was calculated for 6 serves, 3 jump serves and 3 standing overhand serves. Ball velocity was calculated based on distance and flight time. Both of these variables were discovered through Dartfish Analysis Software. Table 3 displays the summarized

This confirms what the literature has found as well. The jump serve is more likely to have a decreased flight time, an increased ball velocity and a flatter projection angle. My hypothesis of which serve would be considered better was confirmed, but I was surprised at the minimal difference of each factor between each serve. I assumed that each factor would be significantly different between the two serves. Based on my results, I can confirm that the jump serve is the better volleyball serve in a competition setting. The reduced flight time allows competitors less time to react to the ball, the increased ball velocity makes it more difficult to handle and control and the flatter projection angle makes it more difficult to pass. Therefore, the jump serve is more likely to earn points in a competition

Tennis serve is the shot that starts off the point. It is normally instigated by pitching the ball into the air and thumping it into the diagonally opposite service box exclusive of touching the net. This act is attained underhand or overhead. It is the only attempt where a player takes his time to position up, instead of reacting to an opponent’s shot. In doing this, high percentages of the efforts are normally exerted at the upper extremity of the body, while the rest at the lower extremity of the body. the serves comes in five main types of which includes; cannonball or flat serve, topspin-slice serve, slice serve, American twist serve and the topspin serve. The paper will focus on the some of the types of the serves and the ways in which the upper extremity are involved in the game. With this, it will look at the movements that occur at each of the upper extremity together with the muscles that are in use at the joints.
The goal of this lesson is for my students to understand the fundamentals of completing a successful bump, set, spike, and underhand serve. These aspects will be important when working with their teammates in a positive manner to complete these tasks and use these components to be successful in game play.
ball that has been hit is .42 second. Their reaction time depends on a number of things. Such as
Limb length has a significant role to play in the success of the tennis serve which can evidently be seen in that over the last few decades the sport of tennis has had few professional players that are shorter than 180cm (McLester & St.Pierre, 2008, p 240).
Tennis is a game of speed and reflex. It uses a lot of muscle memory. You need to be able to move quickly and effectively to reach the ball quickly and hit it. Thus it takes quick reaction time and reflexes to play at higher levels. Tennis drills and practices train your muscles to react faster, smoothly and naturally. During fast volley bouts your muscles often react
Speed gives a tennis player many advantages. Firstly, your reaction speed is really important too react to a ball being play to your side of the net. In tennis you have too respond really quick to be able to get too the ball on time one tip is to stand on your toes so that you as a player can respond quicker. Furthermore, you need it too move your body around the court. Moreover, the quicker your brain responds to your body the more time you have to run towards the ball. Lastly, speed is crucial in tennis because it makes a player react quicker and be able to hit the ball back easier using there speed to get to the ball on
Two different exercise groups were compared to see if velocity and accuracy of the tennis serve improved following a six-week exercise programme. Results of this study did not demonstrate a significant change in velocity and accuracy between pre-test and post-test data. However, the whole-body exercise group did show a significant improvement in velocity compared with the scapular stabilising exercise group. This highlights how the use of the LEX in the kinetic chain of the serve can influence the velocity more than solely

The average time to reach the port was averaged for each option 1 from the data given
In order for maximum force to be generated, a tennis player needs a good stable base from where they can begin the movement. The tennis serve begins with flexion of the knee joint caused by the hamstrings. Then comes extension of the knees as well as hip flexion to start the movement - both of these movements are initiated by the quadriceps. The Erector Spinae muscle causes trunk extension to allow the abdominals to fully flex the trunk and generate the force that is then transferred to the upper body. The deltoids and pectorals major are used to flex the shoulder. These muscles are used to accelerate the whole arm while also stabilising the shoulder. Once the arm has begun to accelerate towards the ball, the tricep brachii is then used to
5)Serving is a very important element of volleyball. A server who can serve the ball reliably and skillfully will help his or her team far more than will a player who, for instance, is inconsistent with their serving. There are a variety of serves that are employed in competitive volleyball, from "floaters" that seem to shimmy and shake on their way over the net to hard-driven jump serves.
For the warm-ups before practice I will have the players start by running these drills to get the blood flowing: The Courier Drill, Spiders, and Cross Court line touches. After this practice will commence with various stroke preparation drills such as cross-court/down the line and a point blank volleying drill to develop better hand-eye coordination and racquet preparation. In the cross-court/down the line drill there will be four people to each court and players on opposite sides of the court will plays five point games while alternating drop serves. One player is only allowed to hit the ball cross-court while the other player is allowed to hit the ball
Moreover, hitting only at the waist level and not at a spiking level was also another good aspect. I neglected showing my students when it was appropriate to use a backhand drive vs. a forehand pass.
