Topic: Ball Games: (Volleyball)
WEEK: 5 & 6
Volleyball is a sport in which two teams compete against each other. The objective is to use their hands to hit a large inflated ball over a high net, with the aim of making it land on the opposing team’s court. The governing body responsible for regulating volleyball worldwide is the Federation Internationale de Volleyball (FIVB), also referred to as the International Federation of Volleyball. This organization was established in 1947 and has since been dedicated to promoting and developing the sport globally. Volleyball was included as an Olympic sport for the first time in 1964 at the Tokyo Olympics.
Brief History of Volleyball
Volleyball was introduced to Nigeria in the early 1960s, shortly after the country gained independence from Britain. The sport quickly gained popularity, and in 1964, the Nigerian Volleyball Association (NVA) was formed.
The NVA organized the first National Volleyball Championship in 1965, which saw the participation of teams from various parts of the country. The championship continued to be held annually, and it helped to popularize the sport across Nigeria.
In 1976, Nigeria hosted the African Volleyball Championship for the first time, and the national team won the tournament. The team went on to win the championship four more times, in 1981, 1991, 1995, and 1999.
In 1984, the NVA has renamed the Nigeria Volleyball Federation (NVBF), and it became the governing body for volleyball in the country. The NVBF has since then been responsible for the organization of national and international volleyball events, as well as the development of the sport at the grassroots level.
In recent years, Nigeria’s volleyball teams have continued to perform well in international competitions. In 2019, the women’s team won the All-Africa Games volleyball tournament, while the men’s team finished second in the African Volleyball Championship.
The Volleyball Court Dimension
|Court size||18 meters x 9 meters||The court is a rectangular area that measures 18 meters in length and 9 meters in width.|
|Net height||2.43 meters||The net is positioned at the centre of the court and is 2.43 meters high for men’s matches and 2.24 meters high for women’s matches.|
|Antenna length||1.80 meters||Two antennae are attached to the net on either side of the court, extending 1.80 meters from the poles.|
|Attack line||3 meters from the net||The attack line is a line drawn parallel to the net, 3 meters away from it. Front-row players can jump from behind the attack line to attack the ball. Back-row players are not allowed to jump from behind the attack line unless they take off behind the line and land in front of it.|
|Service line||2.6 meters from the net||The service line is a line drawn parallel to the net, 2.6 meters away from it. Servers must stand behind the service line when serving the ball.|
|Centerline||Divides the court in half||The centre line divides the court in half, running perpendicular to the net. It is used to determine which team is serving and to mark the boundary for front-row players.|
|Sidelines||Mark the width of the court||The sidelines run parallel to the net and mark the width of the court.|
|End lines||Mark the length of the court||The end lines run perpendicular to the net and mark the length of the court.|
|Attack area||9 meters from the net||The attack area is the area on each side of the net where front-row players are allowed to jump and spike the ball. It is marked by lines that extend 9 meters from the net and converge at a point above the center of the net.|
|Substitution zones||3 meters from the end line||There are two substitution zones on each side of the court, located 3 meters from the end line. Players must enter and exit the game from their team’s substitution zone.|
These dimensions are used in indoor volleyball, but there are some variations in the court size and net height used in beach volleyball.

The Skills and Techniques in Volleyball
The basic skills and techniques in volleyball are;
- Serving: This is the act of initiating the game by putting the ball into play. It is usually done by a player from behind the backline and can be done in various ways such as jump serves, float serves or underhand serves. Jump serves involve jumping before striking the ball, float serves to involve a low-speed spin on the ball, while underhand serves are done with the hand below the waist.
- Passing: This is the act of receiving and controlling the ball after an opponent’s serve. The objective of passing is to keep the ball in play and prevent it from touching the ground. Passes are usually done with the forearms, and players should try to pass the ball towards their team’s setter for a better chance of scoring.
- Setting: This is the act of accurately and strategically placing the ball above the net for a teammate to attack or spike. The setter usually uses their fingertips to control the ball’s direction and speed, and the objective is to make it easier for the hitter to score by putting them in a good position to make a successful attack.
- Spiking: This is the act of hitting the ball forcefully over the net to the opponent’s court, with the aim of scoring a point. The spiker usually jumps before hitting the ball, and the objective is to make it hard for the opposing team to dig or block the ball. Spiking requires good timing, technique and power.
- Blocking: This is a defensive move that involves stopping an opponent’s spike by jumping and positioning oneself in front of the net. The blocker’s objective is to prevent the ball from crossing the net, either by deflecting it back to the opponent’s court or forcing them to make an error. Blocking requires good timing, coordination and jumping ability.
- Digging: This is the act of making a defensive move to prevent the ball from touching one’s court after an opponent’s spike. It involves using the forearms and fingers to control the ball’s direction and speed, and the objective is to keep the ball in play and prevent the opponent from scoring. Digging requires quick reflexes, good technique and agility.

Common Injuries in Volleyball
The most common injuries in volleyball are:
Volleyball is a popular sport that involves quick movements, jumping, and repetitive motions. As a result, players are at risk of various injuries that can range from minor to severe. Here are some of the most common injuries in volleyball and their explanations:
- Ankle sprains – Ankle sprains are the most common injury in volleyball. They occur when the ligaments in the ankle are stretched or torn. This injury often happens when a player lands awkwardly after a jump or when they pivot quickly on one foot.
- Knee injuries – Volleyball requires a lot of jumping and sudden changes in direction, which can put a lot of stress on the knees. Knee injuries can range from minor strains and sprains to more severe injuries like ACL tears.
- Shoulder injuries – Shoulder injuries are common in volleyball because of the repetitive overhead motions used in serving, spiking, and blocking. These motions can lead to overuse injuries like rotator cuff strains, tendinitis, and shoulder impingement syndrome.
- Finger injuries – Volleyball players often sustain finger injuries from blocking or spiking the ball. These injuries can range from simple sprains to dislocations or even fractures.
- Back injuries – Volleyball players are at risk of developing back injuries due to the repetitive jumping, bending, and twisting motions involved in the sport. These injuries can range from minor muscle strains to more severe herniated discs.
- Concussions – Concussions can occur in volleyball when players collide with each other or the ground during a dive or a fall. Players may also sustain a concussion from being hit in the head with the ball.
- Wrist injuries – Volleyball players are also at risk of developing wrist injuries from repetitive motions involved in serving, passing, and hitting the ball. These injuries can range from minor sprains to more severe injuries like tendinitis, carpal tunnel syndrome, or even fractures.
- Hamstring strains – Volleyball players are required to make quick movements and sudden changes of direction which can cause a strain on the hamstring muscles. A hamstring strain occurs when one or more of the three hamstring muscles tear or stretch.
- Achilles Tendonitis – Volleyball players often jump repeatedly which puts a strain on the Achilles tendon that connects the heel bone to the calf muscles. This can lead to inflammation of the tendon and pain in the lower leg.
- Plantar Fasciitis – Plantar fasciitis is a common injury in volleyball players that involves inflammation of the plantar fascia, which is a band of tissue that runs from the heel to the toes. This injury can cause pain in the heel or arch of the foot and can be caused by overuse, improper footwear, or poor foot structure.
- Groin strain – Groin strain occurs when the muscles of the inner thigh are overstretched or torn. Volleyball players are at risk of this injury due to the quick and sudden movements involved in the sport, such as jumping and diving.
- Heat exhaustion – Volleyball is often played in hot and humid conditions, especially during the summer months. This can cause players to become overheated, and dehydrated, and experience symptoms of heat exhaustion like dizziness, weakness, and nausea.
Practical Demonstration of Skills in Volleyball
While the skills required in volleyball are diverse, there are a few fundamental skills that are essential for players to master. Here are some practical demonstrations of skills in volleyball:
- Jogging round: Jogging around the court is an essential skill for warm-up and endurance building. It helps in loosening up the body and preparing the muscles for the game.
- Hand swinging: Hand swinging is a skill used for serving, spiking, and blocking. Players need to practice swinging their arms to generate power and accuracy in their shots.
- Windmill: The windmill is a technique used for spiking. It involves swinging the arm in a circular motion, generating maximum power and speed in the ball.
- Beating imaginary drum: This technique is used for forearm passing or digging. It involves hitting the ball with the forearm, much like one would hit an imaginary drum.
- Running on the spot: Running on the spot is another warm-up exercise that is used to build endurance and stamina. Players need to practice this skill to maintain their energy levels during the game.
- Waist rotation: Waist rotation is used for setting the ball. It involves rotating the waist to generate the necessary power and accuracy in the shot.
- Press up: Press up is a strength-building exercise that is used to improve the player’s overall strength and stamina. It helps in developing the upper body muscles, which are essential for volleyball.
- Frog jump: The frog jump is a technique used for blocking. It involves jumping up and extending the arms to block the opponent’s shot. It requires explosive power and quick reflexes.
- The practical demonstration skill in volleyball refers to the ability to serve the ball over the net using various techniques such as underarm, overhead, windmill, or push, with one hand open or closed, or any part of the arm. The objective is to send the ball into the opponent’s court, either to score a point or to start a rally.
- To perform a successful service, the player must first position themselves behind the baseline and wait for the referee’s signal whistle before executing the serve. Their legs must be behind the line when making the service.
- Underarm service is when the player holds the ball in one hand and swings the other arm in a pendulum motion, hitting the ball with a flat hand to send it over the net.
- Overhead service is when the player tosses the ball up in the air and jumps to hit it with their hand above their head, using either a closed or open hand technique.
- Windmill service involves swinging both arms in a circular motion and hitting the ball with one hand.
- Push service is when the player uses their fingertips to push the ball over the net, usually with a soft touch and a short distance.
- After a game or practice session, players should engage in warm-down activities such as light jogging, breathing in and out, neck rotation and shuttle race to gradually lower their heart rate and reduce muscle tension, preventing injury and promoting recovery.
