The purpose of this study was to determine the influence of the use of bounce on performance in wheelchair tennis. Data pertaining to all the hits on the ball (n = 4021) were recorded from 16 men’s singles professional matches. Performance parameters regarding to players’ skill level (high- and low-ranked) the game situation (players and the serve-return situation), technical-tactical aspects (hitting side), and outcome (stroke and point outcome) were included in multivariate regression and decision tree models. The results determined that the skill level ( χ ( 1 ) 2 = 7.164, p > 0.01) and stroke outcome ( χ ( 2 ) 2 = 14.099, p > 0.01) were the main predictors of the number of bounces, with high-ranked players using more bounces than the low-ranked. Stroke outcome was the main distinguishing factor of the use of bounce ( χ ( 4 ) 2 = 51.424, p < 0.01, V = 0.08), with a greater use of zero bounces in winners and errors, one bounce in rallies, and two bounces in winners. These findings should be taken into consideration by coaches to design specific training systems according to the requirements from wheelchair tennis.

专业轮椅网球中弹跳的运用

本研究的目的是确定使用弹跳对轮椅网球表现的影响。与所有击球次数（n = 4021）相关的数据是从 16 场男子单打职业比赛中记录的。有关球员技能水平（排名靠前和排名靠后）、比赛情况（球员和接发球情况）、技战术方面（击球方）和结果（击球和得分结果）的性能参数被包含在多变量中回归和决策树模型。结果确定技能水平（ χ ( 1 ) 2 = 7.164, p > 0.01）和卒中结果（ χ ( 2 ) 2 = 14.099, p > 0.01）是弹跳次数的主要预测因子，排名靠前的比排名低的玩家使用更多的弹跳。卒中结果是使用反弹的主要区别因素（χ (4) 2 = 51.424，p < 0.01，V = 0.08），更多地使用赢家和错误中的零反弹，反弹中的一次反弹，赢家中的两次反弹。教练员应考虑这些发现，根据轮椅网球的要求设计特定的训练系统。
