Trackman便携式发射监测器已成为精英高尔夫球手的流行评估和反馈工具，其中包括巡回赛专业人士和美国大学球队。该设备符合评估高尔夫性能的重要标准，包括便携性、准确性、可靠性和即时反馈。这项研究的目标是评估将Trackman引入大学高尔夫球队的潜在好处，并基于设备数据对性能进行批判性检查。在前测-后测设计中，10名平均击球障碍为6杆的大学高尔夫球手在相隔8周的两个不同时间点对不同距离的击球表现进行了评估，测试工具是Trackman“Combine”标准化测试。结果表明，评估时间点与射击距离之间没有显著的交互作用(p=.625)，也没有显著的主效应(p=.995)。然而，距离有一个主要效应(p<；.001)，与处于中间水平的高尔夫球手相比，高尔夫球手在短距离和远距离击球上的挣扎更多。最短60码的成绩明显低于100码(p=.009)、120码(p=.019)和140码(p=.047)。更远距离160码和180码的表现明显逊于100码(分别为p=.020，p=.010)和120码(分别为p=.041，p=.020)，而驾驶员的表现显著低于80码(p=.001)、90码(p=.001)、100码(p<；.001)、120码(p<；.001)和140码(p<；.001)。这些发现表明，使用这种技术进行八周的定向和练习并不会显著改变关于不同球门距离的射门质量的基线测试结果。此外，在目前的研究中，高尔夫球手在中等长度(即80-140码)的击球上表现得相当出色，同时在这一范围之外表现出更高水平的可变性。对实践结构和性能的影响进行了讨论。
The Trackman portable launch monitor has become a popular tool of assessment and feedback among elite golfers, including tour professionals and U.S. collegiate teams. The device meets important criteria for assessing golf performance, including portability, accuracy, reliability, and instantaneous feedback. The goals of this study were to evaluate potential benefits of introducing the Trackman to a collegiate golf team and critically examine performance based on device data. In a pretest-posttest design, female collegiate golfers (n = 10) with an average handicap of six strokes were assessed on shot performance at varying distances at two different time points eight weeks apart using the Trackman “Combine” Standardized Test. Results indicated no significant interaction between the time point of assessment and shot distance (p = .625) and no significant main effect for time point (p = .995). However, there was a main effect for distance (p < .001), such that golfers struggled more with short and long shots when compared with those in the middle of the spectrum. Performance at the shortest yardage of 60 was significantly worse than 100 (p = .009), 120 (p = .019), and 140 yards (p = .047). Performance at longer distances of 160 and 180 yards was significantly worse than 100 (p = .020, p = .010, respectively) and 120 (p = .041, p = .020, respectively) yards, and driver performance was significantly worse than 80 (p = .001), 90 (p = .001), 100 (p < .001), 120 (p < .001), and 140 (p < .001) yards. These findings suggest that eight weeks of orientation and practice with such technology do not significantly alter baseline testing results regarding shot quality at varying goal distances. Furthermore, golfers in the current study comparably excel at golf shots of intermediate lengths (i.e., 80 – 140 yards) while demonstrating higher levels of variability outside this range. Implications for practice structure and performance are discussed.
