The distance from which a basketball shot is taken can have a significant impact on its accuracy and overall outcome. As the shooting distance increases, the horizontal virtual target decreases, demanding greater spatial accuracy and different movement strategies from the player. Several studies have analysed the effects of distance on shooting performance, with some observing that longer shots result in reduced accuracy and changes in ball release height, angle, and velocity. Other factors, such as the athlete's vision, shooting technique, and kinematic characteristics, also come into play when understanding the complex relationship between distance and shooting proficiency in basketball.

The effect of distance on shooting accuracy
Distance has a significant impact on shooting accuracy in basketball. As the shooting distance increases, the horizontal virtual target decreases, demanding greater spatial accuracy and precision from the shooter. This means that the further away from the basket the player is, the more accurate they need to be to make the shot.
Several studies have analysed the effect of increased distance on basketball jump shot accuracy. One study found that shot accuracy decreased from 59% at close range (2.8m) to 37% at long-range (6.4m). This decrease in accuracy with increasing distance is attributed to the changes in ball release height, angle, and velocity. As the distance increases, the ball release height and angle tend to decrease, while the ball release velocity increases. These adjustments are essential to compensate for the greater distance and maintain accuracy.
The increased distance also affects the player's movement and shooting form. Greater shooting distances require players to make compensatory adjustments, such as greater shoulder flexion, elbow extension, and centre of mass displacement towards the basket. These changes in movement strategies help players adapt to the increased distance and aim for the smaller target.
Additionally, the shooting distance influences the force requirements and the transfer of energy from the lower limbs to the arms. Longer shots demand more force to propel the ball towards the basket, resulting in greater flexion in the knee and hip joints, along with lower elbow positioning. These adjustments help players generate the necessary power to make shots from longer distances.
The player's vision and visual information also play a crucial role in shooting accuracy. Studies have shown that better accuracy is achieved when players have a complete view of the basket, as it allows them to adjust their shooting form and aim more effectively.

The impact of distance on ball release velocity
Research has shown that increasing the shooting distance results in higher ball release velocities. Satern (1993) found that players achieved greater ball release velocity by utilising a greater arm joint range of motion. Similarly, Elliott and White (1989) observed greater shoulder angular velocities and increased movement amplitudes around the shoulder and wrist in female basketball players when shooting from longer distances. These findings suggest that players compensate for the increased distance by applying more force to the ball, resulting in higher release velocities.
However, it is important to note that the relationship between distance and release velocity is complex. While longer distances may lead to higher release velocities, other factors, such as release angle, also come into play. Okazaki and Rodacki (2015) found no significant difference in angular amplitude between short-, mid-, and long-range jump shots, indicating that release angle may not vary significantly with distance. Additionally, individual shooting release velocity and angle standard deviations have been found to remain consistent across distances, suggesting that these factors may be more dependent on the shooter's technique and proficiency rather than the distance itself.
The increase in release velocity with distance can also be attributed to the need to generate more force to propel the ball towards the basket. As the shooting distance increases, players adjust their shooting form by increasing flexion in the knee and hip joints, while lowering their elbow positioning. These kinematic adjustments help compensate for the increased distance and ensure the ball reaches the target.
Furthermore, the impact of distance on release velocity is influenced by the player's visual information. Studies have shown that better accuracy is achieved when players have a complete view of the basket. As the shooting distance increases, the player's field of view may change, impacting their ability to accurately judge the required release velocity and angle. Therefore, the interaction between distance, visual input, and release velocity is a critical aspect of shooting performance in basketball.

How distance affects the player's shooting form
Distance is a key factor in basketball shooting performance. As the distance increases, the horizontal virtual target decreases, requiring greater spatial accuracy. This means that players must adjust their shooting form to account for the increased task constraints.
One way players can do this is by increasing the ball release velocity. Studies have shown that players are able to increase release velocity by using a greater arm joint range of motion, resulting in greater shoulder angular velocities and greater movement amplitudes around the shoulder and wrist. This is particularly true for female basketball players.
In addition to changes in release velocity, players may also need to adjust their release angle when shooting from longer distances. A decrease in release angle with an increase in shooting distance has been observed, and players should look to find the optimal release angle to improve accuracy.
The kinematic characteristics of the shooting motion also change with distance. For example, three-point shots require lower elbow positioning and greater flexion in the knee and hip joints compared to free-throw and two-point shots. These adjustments are made to generate more force to propel the ball towards the basket and compensate for the increased distance.
Finally, distance can also affect a player's vision and gaze behavior, which in turn can impact shooting accuracy. Studies have shown that better accuracy is obtained when players have a complete view of the basket, rather than only seeing it after shooting.

The influence of distance on the player's vision
The influence of distance on a player's vision is a critical aspect of basketball. Shooting accuracy is a key performance parameter in basketball, and it is influenced by the player's ability to adjust their shooting form and technique as the distance from the basket increases.
As the distance increases, the player's visual target decreases, requiring greater spatial accuracy. This means that players need to be able to process visual information quickly and accurately to make the necessary adjustments to their shooting angle and velocity. Studies have shown that players with a complete view of the basket tend to have better accuracy than those who only see the basket peripherally or after releasing the ball.
The impact of distance on vision is particularly evident when comparing free-throw shots (4.57 m) to three-point shots (6.75 m). The longer distance of three-point shots requires players to make more significant biomechanical adjustments, such as greater flexion in the knee and hip joints and lower elbow positioning, to generate the necessary force to propel the ball towards the basket. These adjustments can affect the player's field of vision and the amount of visual information they can process before releasing the ball.
Additionally, the increased distance can impact the player's ability to focus on the target and make precise movements. As the distance increases, the margin for error decreases, and small inaccuracies in the release angle or velocity can result in missed shots. This is supported by studies that observed a decrease in shooting accuracy as the distance from the basket increased.
Furthermore, the presence of environmental constraints, such as simulated opposition or gym audience noise, can also influence the player's vision and shooting accuracy. These factors can create visual distractions or block the player's line of sight, affecting their ability to process visual information effectively. Overall, the influence of distance on a player's vision is a critical aspect of basketball performance, and understanding these visual constraints can help players develop more effective shooting techniques and strategies.

The effect of distance on the transfer of energy from the lower limbs to the arms
The act of shooting a basketball is a complex one, and a successful shot is the result of a multitude of factors. One of the most important factors is the distance from which the shot is taken. As the distance increases, the player must adjust their shooting form to generate more force to propel the ball towards the basket. This force is generated through greater flexion in the knee and hip joints, along with lower elbow positioning. These adjustments are necessary to compensate for the increased distance and ensure the ball reaches the target.
The transfer of energy from the lower limbs to the arms is crucial in this process. As the shooting distance increases, the player needs to apply more force, which is generated through greater lower body motion and an increase in release velocity. This was observed in a study by Miller and Bartlett (1993), who noted greater shoulder flexion, elbow extension, and displacement of the center of mass towards the basket as shooting distances increased.
The effect of distance on the transfer of energy was also studied by Okazaki et al. (2004), who found that longer shots required greater accuracy due to the decrease in the horizontal virtual target as distance increased. This accuracy is influenced by the release angle and velocity of the ball, which are dependent on the distance from the basket. As the distance increases, the release angle tends to decrease, while the release velocity increases. This relationship was observed in a study by Satern (1993), who found that players were able to increase release velocity by using a greater arm joint range of motion when shooting from longer distances.
The transfer of energy from the lower limbs to the arms is also influenced by the player's visual information. A study by Oliveira et al. found that better accuracy was achieved when players had a complete view of the basket, as it allowed them to adjust their shooting form and transfer energy more effectively. Overall, the effect of distance on the transfer of energy from the lower limbs to the arms is a complex interplay of biomechanical adjustments, force generation, and visual information processing, all of which contribute to the outcome of the basketball shot.
