Performance analysis during match play is vital for the long-term development of tennis players. The primary goal of this study was to establish the differences between junior and entry professional tennis player's selected performance indicators in five-game situations. Data were collected using the Sagit/Tennis tracking system during six junior and four professional tennis matches. Eight boys performed 3,112 strokes, while eight male professional players hit 1,631 strokes. The results showed slight differences in the distance covered by the two observed groups in the specific game situations. Professional players performed faster shots in all game situations, except when playing at the net. They played at a significantly faster tempo than the juniors. This difference was also affected by the higher shots speed and shorter distance between the two players during the rallies. When playing from the baseline, the entry professional players performed shots at a smaller angle than the juniors; and when serving, receiving and playing at the net, they hit shots at a greater angle than the juniors. Our findings may assist coaches and players in improving the effectiveness of their tactical and technical training to enhance their competitive performance.

比赛期间的表现分析对于网球运动员的长期发展至关重要。这项研究的主要目标是确定五场比赛中初中和入门职业网球选手选择的性能指标之间的差异。在六场初级和四场职业网球比赛中，使用Sagit / Tennis跟踪系统收集了数据。八个男孩打了3,112杆，而八个男性职业球员打了1,631杆。结果显示，在特定游戏情况下，两个观察组所覆盖的距离略有差异。专业玩家在所有游戏情况下的击球速度都更快，但在网上玩时除外。他们的节奏比大三学生快得多。这种差异还受到集会期间两名球员之间更高的射门速度和更短距离的影响。从基线开始比赛时，入门级职业选手的射击角度要比少年组小。在发球，接球和打球时，他们投篮的角度要比少年球员大。我们的发现可能会帮助教练员和球员提高战术和技术培训的效率，以提高他们的竞技表现。
