Volleyball players tend to be long, lean athletes. Greater height allows players to play the ball above the net, executing spikes and performing blocks. Taller athletes also cover more court and have longer arms, allowing them to

generate more power when striking the ball. Due to the height of the net, which stands eight (8) feet high for men, good volleyball players need exceptional jumping ability. Strong vertical leaps allow players to get above the net for scoring opportunities and defensive plays. Jumping can also play a role in serving by creating more dynamic hits and power (Crowther, Spinks & Leicht, 2007).
The game's constant jumping and quick movements tax the legs and will test aerobic stamina. This will require volleyball players to work both aerobic and anaerobic energy systems, making cardiovascular conditioning very important. The aerobic capacity will help build a strong cardiovascular base that is needed for a long match (Markovic & Mikulic, 2010).
Vertical jump is defined as the ability to achieve the greatest vertical height at takeoff (Dowling & Vamos, 1993). The vertical jump is easily performed by most healthy individuals, yet some are considerably more proficient than others. Vertical jump performance appears dependent upon the contractile properties of the muscle, as well as the

Plyometric training (PLY) is a very popular form of physical conditioning of healthy individuals and certain patient populations (e.g. osteoporotic patients). It involves performing body weight jumping-type exercises and throwing medicine balls using the so-called stretch-shortening cycle (SSC) muscle action. The SSC enhances the ability of the neural and musculotendinous systems to produce maximal force in the shortest amount of time, prompting the use of plyometric exercise as a bridge between strength and speed (Markovic & Mikulic,
Throughout literature countermovement jumps (CMJ) are seen to be higher in contrast to squat jumps (SJ) (Bobbert et al. 1996; Kubo et al. 1999; Bobbert et al. 2005). However present literature regarding the key potential mechanisms behind why greater muscle forces are seen accelerating the body upwards in CMJ in comparison to SJ is somewhat unclear. A CMJ can be defined as a positioning starting upright, beginning the descending motion in advance of the upward motion in contrast to a SJ where the start position is squatted with no preparatory countermovement (Akl 2013). The higher jump heights seen in CMJ in comparison to SJ are apparent even if at the start of propulsion phase the body configuration is identical (Bobbert et al. 1996). In past literature three main mechanisms have looked to provide an explanation for the greater muscle forces seen in CMJ than the SJ. The first plausible theory is that the muscle stretch in CMJ increases the production of force capability of the contractile machinery (Edman et al. 1978; Ettema et al. 1992; Herzog et al. 2003). Secondly the assumption that the muscle fibres are on the descending limb of their force–length relationship at the start of propulsion in the CMJ and SJ, however in CMJ the stretching of a chain of elastic components, they are not as far past optimum length therefore allowing a greater force over the initial phase of their shortening range, with the stretching of sequences of elastic components, this then causes the storage of elastic energy that is then reutilized in the propulsion phase (Ettema et al. 1992). The final explan...
I practically was born with a ball in my hands, and whether it was bumping the ball around the house or knocking over things that just happened to be in my path, I was always with my precious volleyball. My family is also rooted into into the sport. After my mom’s high school team at Central won the state championship, she went on to play at Southeast Missouri. She has been an inspiration to me, and at 10 years old I began to play club volleyball thanks to her. Being one of the youngest on my team, I never got much playing time, but that year of watching and learning helped me settle into a team the year
I have played volleyball for 5 years. I have played school volleyball for five years, and club volleyball for four. Throughout my years of playing, I have recognized a significant difference between club volleyball and school volleyball. I have played for two clubs in my four years of playing club. The first two years, I played for a club named Platform Elite. The last two years, I have played for Iowa Select, and this year I am playing my club season with Infinity X. Personally, I prefer club volleyball over school volleyball. Club volleyball and school volleyball can be compared in three different categories: price, competition, and “politics” within the sport and its’ players.
Research suggests a person’s height does not affect their ability to make a successful jump shot. The ability to make a successful jump shot be determined by the arc in which enters the rim of the basket. When a basketball enters the rim on a 45° angle with a backspin it increases the percentage of a successful jump shot. The height of a basketball player is key when the player is taller, they are able to make more successful defensive blocks and able to get more rebounds of the basketball.

Evidence of lifting weights can be traced back to the origins of man. As far back as cave painting and scrolls, there exists evidence of weightlifting. Initially as an expression of strength, to competition and functional training, weightlifting has carved its path through the ages. It has taken on a new role in the modern world; athletic training. With an entirely new emphasis in sports on speed, strength, and flexibility; weightlifting is more popular than ever. Unfortunately, young athletes often do more harm than good by injuring themselves lifting. When these uneducated lifters try to jump right into a program, lifting more than they should, an injury is imminent. What is overlooked, is that when weightlifting is done correctly, it has a great potential to prevent injuries instead of cause them. Understanding how the body works, using proper technique on the appropriate lifts, and participating in regular physical activity can greatly reduce the risk of athletic injuries.
Volleyball is a great sport, it is very fun!! The attire for volleyball is a jersey, shorts, knee pads and special volleyball shoes. Some equipment that you need to play volleyball with, first of all you need a net, ball, 6 players on a court, court, referee,
If the material of the ball is changed, then the ball with the most elasticity in its material, which is the basketball, will produce the greatest bounce height. This is because balls with greater elasticity in their material will lose less energy to heat and sound since it has the ability to decelerate slower due to its flexible material and thus, will transfer more kinetic energy to elastic potential energy more efficiently causing the ball to bounce

...be related to a football player who desires to increase or improve their skills. A football player may achieve such results by performing a particular activity with increasing resistance, increasing speed, increasing duration, or any combination of these. (Dick, 2002, pg. 218) For example, if a defensive back desires to increase his strength; defensive backs are required to be strong and powerful. A defensive back could increase the training volume performed in seated bench press as a means of achieving overload.
This research task requires that, through participation in skill learning and game play during the volleyball unit we have been required to observe and analyse the characteristics of skilled performers; receive feedback on weaknesses in technique and develop and participate in training activities that could correct these weaknesses.
Illustrating the arrangement of players mathematically requires that one understand the standard dimensions of a volleyball court. According to Lithio and Webb (2006), a standard volleyball court resembles a rectangle, which is 59 ft long by 29 ft, 6 in. wide. A net, centrally placed, separates the court into two squares. Stretching from the end of every side of the volleyball court is an area from which the ball is served, at least 6 ft wide. A player can stand in any region of this area to serve (consider figure 1) (Lithio & Webb, 2006).
The first step towards the process of shooting is jumping, which might sound simple and silly, but it actually is a very tricky process. It is difficult for athletes to shoot off a dribble, or jumping over other humans to get the shot off. All these situations that happen during a game need balance and correct foot stances for the proper jump. The in game athletes, like the in the NBA has to adjust their foot stances to have and maintain balance for the textbook shot. Also, they bend their knees before jumping to gain and add momentum to their shot. When shooting, athletes should jump upward not forward. They should also sweep their feet forward when they shoot, hence their feet don’t land in the same position where it started, because, if that happens, it can cause
