vision training

for VOLLEYBALL players

Volleyball requires players to have great positional and spatial awareness on the court, along with excellent reaction times to quickly get in position and make a play off of a hit, serve or block. Great anticipation for incoming hits can separate average and elite volleyball players.

the core six

visual skills

Understanding an athlete’s proficiency in the six core visual skills allows players, coaches, and scouts to identify and correct visual weaknesses and enhance the athlete’s performance on the court.
reaction time
ball tracking
Hit accuracy
spatial relations
convergence small
Convergence
Focus on incoming serve or hit, impacting a player's defensive positioning and anticipation on the court.
divergence small
Divergence
Pinpoint a location across the court to accurately hit the ball. Locating and following opponent's movements across the court.
depth small
Depth
Impacts a player's judgment to attempt a set, block or dig. Enables players to successfully judge the speed, spin and trajectory of the ball, along with positional and spatial awareness on the court.
alignment small
Alignment
Increases precision with serve, set and hit accuracy, along with overall likelihood of hitting intended target.
recognition small
recognition
Identify opponent's tendencies, set plays, and general movement. Impacts a player's hit anticipation, and overall volleyball IQ.
Tracking small
TRACKING
Anticipate the flight of the ball and success-rate of connecting on hits. Locate incoming hits through traffic. Enhances general monitoring of developing play.

taking a look

at positions

Depending on the position an athlete plays, the visual skills required for optimal performance vary. Outside hitters, for example, may struggle to react to a hit and quickly dig, simply due to the nature of their position. Understanding your role on the court, and the visual skills needed to thrive in that position can help lead your team to success. 

setters


Setters are the play-makers of the team and without a great setter, a team's offense will likely struggle. Setters typically posses great blocking, digging and play making skills, along with general game-play tactics. Strong convergence skills are needed to help a setter focus on an incoming pass or hit. Having weaker convergence skills might expose a setter, as they will likely see the ball late coming off a pass or hit. Judging a ball's spin, speed and trajectory is also critical for success as a setter. Having great depth perception skills can also help a setter judge the timing of a jump or dig, and combined with great alignment skills, accurately line up a set. Running the team's offense and identifying an opponent's blockers, means the setter needs to be quick to process information and having strong recognition skills can separate elite setters from average ones.

Attackers


While the three hitting positions in volleyball are entrusted with different responsibilities throughout the course of the game, they all need to possess similarly strong visual skills. Outside hitters need to be able to time their jump accordingly to connect on a pass from the setter, in order to generate the most power and accuracy on a hit. This requires perfect alignment, along with great usage of their visual flexibility skills (convergence and divergence), to first receive a pass and hit their intended target on the opponent's side. Opposite hitters need to have great blocking skills, since they are directly against an opponent's outside hitter. Having great positional awareness on the court, along with strong recognition skills to appropriately time a jump, can help an players in this position succeed. Middle hitters/blockers are key to a team's success. Often the tallest player on the team, but strong visual skills are also needed to read the flow of the game or identify an opponent's hitting tendencies, which directly relates to their recognition skills.

liberos & Defensive specialists


Strong defensive skills help liberos and defensive specialist (DS) succeed at all levels of the game. This requires excellent receiving of a serve, along with great digging skills to keep the play alive. Similar to setters, liberos and DS players need great convergence skills to see and focus on an incoming serve or hit. Great anticipation (recognition) and reaction times (tracking) are critical to the success of a libero and DS. Players who possess these skills are able to quickly get into a defensive position for a dig or serve receive, and respond appropriately. Defensive specialists need excellent tracking skills to pursue the movement of a ball at any given time. Along with being a defensive anchor, liberos also play a key role on offense, needing to turn their first touch on the ball into a usable pass for the setter. Having great depth perception can help both liberos and defensive specialists judge the spin, speed and trajectory of the ball and use the appropriate weight on a dig or hit.

breaking down

the edge score

The Edge Score is a comprehensive score given to each athlete based on their most recent evaluation. The score takes all visual skills into account – including convergence, divergence, depth perception, alignment, recognition and tracking. Through analysis of an athlete’s Edge Score as well as their individual scores, we identify areas of weakness and develop an appropriate training program.
convergence small
convergence

Convergence is the ability to focus on objects within close proximity and judge their movement and impact. Convergence may impact a player in the following ways:

  • Ability to focus on an incoming serve or hit
  • Track and successfully connect on hits, digs, and blocks
  • Overall serve receive abilities
divergence small
DIVERGENCE

Divergence is the ability to locate objects in the distance, impact an athlete’s ability to anticipate and react. Divergence may impact a player in the following ways:

  • Locating an opponent’s position across the court
  • Accurately line up a serve to hit the intended target or location on the court
  • Following the location of the ball after a serve
depth small
DEPTH PERCEPTION

Divergence is the ability to locate objects in the distance, impact an athlete’s ability to anticipate and react. Divergence may impact a player in the following ways:

  • Ability to judge the speed, spin and trajectory of the ball
  • Accurately time jumping, blocking, and hitting actions
  • Positional and spatial awareness on the court
alignment small
ALIGNMENT

Proper alignment creates no difference between the perceived location and the actual location of an object. Alignment may impact a player in the following ways:

  • Accurately line up a serve to hit the intended target or location on the court
  • Judge the true location of an incoming ball
  • Timing of jumps, blocks, and hits
recognition small
RECOGNITION

Recognition is the ability to observe, process and recall a series of visual targets, and respond properly. Recognition may impact a player in the following ways:

  • Ability to identify an opponent’s tendencies or set play development
  • Getting in the appropriate position for hits, blocks, digs and sets
  • Overall volleyball IQ
Tracking small
TRACKING

Tracking allows you to process and follow an object while always monitoring all aspects of the game. Tracking may impact a player in the following ways:

  • Monitor the ball and developing play
  • Overall reaction times
  • Anticipation of serves, hits and blocks
