Kinematic adjustments in the basketball jump shot against an opponent

Abstract

The aim of this study was to analyse the adjustments in technique made by a basketball player when shooting against an opponent. The subjects used consisted of 10 professional basketball players of the Spanish First Division League. Threedimensional motion analysis based on video recordings (50 Hz) was used to obtain the kinematic characteristics of basketball jump shots with and without an opponent. It was found that when performing against an opponent the release angle of the ball increased, the¯ight time was reduced and postural adjustments as determined by the angles at the knee and shoulder increased, all signi® cantly. There were several other non-signi® cant diVerences that helped to interpret the changes in technique imposed by the presence of an opponent. It was suggested that when shooting with an opponent, players attempted to release the ball more quickly and from a greater height. This strategy will lessen the chance of the opponent intercepting the ball. It was concluded that the diVerences noted in the technical execution of the skill had implications for practice. It was suggested that training would bene® t from practice with an opponent for at least some of the time to condition players to the demands which they were more likely to meet in the game situation.

Effect of two different forms of three-point line on game actions in girls’ mini-basketball

“…The participants mostly used the standard shot in the first championship. The higher number of standard shots in the first championship was due to the greater number of shot attempts from zones A and C. In zone A, the standard shot increased because the presence of close opponents requires increasing the angle and release height of the ball, and this is achieved with the standard jump shot (Rojas et al, 2000). The shots from zone C were standard because the increase in the distance with regard to the hoop brings about an increase in the speed of ball release (Elliott, 1992;Miller & Bartlett, 1996).…”

A Comparison of Two Landing Styles in a Two-Foot Vertical Jump

“…Our practical interest lies in discovering which of the two styles might have more advantages when making the jump in sports where there is opposition such as basketball and volleyball, and where, in addition to the height reached by the CG, the time required for its execution and the spatial orientation of the corporal segments are factors that determine the performance of the takeoff (18). Moreover, taking into account the high number of jumps made in these sports, a second practical aspect is the prevention of injuries based on the analysis of the valúes reached in the vertical and horizontal forcé components pushing against the ground when taking off for both landing styles.…”

Optimization of a jump shot rhythm at the junior level of basketball performance

“…We can assume, that the faster shot meets the conditions of competitive game and therefore in training sessions it is needed to perform the shots according to the real game environment, paying attention to the proper form of technique. We agree with the position of Rojas et al (2000) occasionally to perform jump shots with an opponent.…”

“…The jump shot is one of the most frequently used methods of shooting in the modern basketball. For example in the Spanish league, it accounts for 41% of all points (Rojas et al, 2000). Based on the results of our previous research which enabled to determine the phase structure and create rhythm models of shooting in elite male basketball (Bazanov, 2001(Bazanov, , 2014) the purpose of this study was to improve the shooting rhythm of jump shot performances of male under 20 years old basketball players.…”

“…For example in the Spanish league, it accounts for 41% of all points (Rojas et al, 2000). Several studies have examined shooting technique at different distances from the basket (Bartlett and Miller, 1996; Okazaki and Rodacki, 2012).…”
