A skill in goal-directed sport performance is an ability involving with many factors of both external and internal concernment. External factors are still developed while internal factors are challenged topic to understand for improving the performance. Internal concernment is explained an effective performance as estimation, solving strategy, planning and decision on the brain. These conjunctions are relevant to somatosensory information, focus attention and fine motor control of cortical activity. Five skilled right-handed golfers were recruited to be subjected of studying the criteria on how to predict golf putt success. Each of their putts was calculated in power spectral analysis by comparing to the pre-movement period. Successful and unsuccessful putt were classified by focusing on the frontal-midline(Fz), parietal-midline(Pz), central midline(Cz), left central(C3) and right central(C4) which supported by few consistency studies that they are related to a primary sensory motor area, focus attention and working memory processing. Results were shown that high alpha power on C4, theta power on Fz, theta power and high alpha power on Pz can be calculated to use as index of predicting golf putt success. Real-time monitoring system with friendly GUI was proposed in this study as promising preliminary study. Expected goal in the future is to apply this real-time golf putting prediction system into a biofeedback system to increase the golf putting's accuracy. However, it still needs more subjects to increase credibility and accuracy of the prediction.
在目标导向的运动表现中,一项技能是一种涉及诸多外部和内部相关因素的能力。外部因素仍在发展,而内部因素则是为提高表现而需深入理解的挑战性课题。内部相关因素被解释为大脑在估计、解决策略、规划和决策方面的有效表现。这些关联与体感信息、注意力集中以及皮层活动的精细运动控制有关。招募了五名熟练的右利手高尔夫球手作为研究对象,以探讨预测高尔夫球推杆成功的标准。通过与运动前阶段进行比较,对他们的每次推杆进行功率谱分析。通过关注额中线(Fz)、顶中线(Pz)、中央中线(Cz)、左中央(C3)和右中央(C4)来区分成功和不成功的推杆,少数一致性研究表明这些区域与主要感觉运动区、注意力集中和工作记忆处理有关。结果表明,可以计算出C4上的高阿尔法功率、Fz上的θ功率、Pz上的θ功率和高阿尔法功率,作为预测高尔夫球推杆成功的指标。本研究提出了具有友好图形用户界面的实时监测系统,作为一项有前景的初步研究。未来的预期目标是将这种实时高尔夫推杆预测系统应用于生物反馈系统,以提高高尔夫推杆的准确性。然而,仍需要更多的研究对象来提高预测的可信度和准确性。
