A High-Efficiency Training Tool for Basketball Players \u2014 The Athlete Tracking System<\/strong><\/p>

With accurate shooting and agile dribbling, athletes give it their all \u2014 and behind their physical prowess lies the support of scientific training.Since early 2021, Professor Tzyy-Yuang Shiang from the Department of Athletic Performance at NTNU has led a sports science team collaborating with the NTNU women\u2019s basketball team, using the athlete tracking system to collect on-court physical data and formulate precise training plans to enhance performance.<\/p>

The Local Positioning System (LPS) works similarly to GPS, but the latter relies on satellite signals and thus cannot be used indoors. LPS, with higher precision and no such limitations, uses indoor base stations to track athletes\u2019 movements, calculate speed and acceleration, and help coaches immediately assess player condition and make optimal decisions.<\/p>

Science Meets Sports to Assist the Women\u2019s Basketball Team<\/strong><\/p>

The driving force behind the athlete tracker, Professor Tzyy-Yuang Shiang, holds a Ph.D. in Mechanical Engineering from Penn State and, aside from specializing in biomechanics, is also a sports enthusiast. During a collaboration with Nike in the U.S., he discovered that engineering could be seamlessly integrated with sports science, which led him to conduct the research at Taiwan\u2019s National Training Center upon returning home.<\/p>

When talking about the origin of the system, Professor Hsiang noted that tracking athlete movement indoors had always been difficult, which prompted him to begin doing research on the LPS system.<\/p>

Coincidentally, a tech company was seeking collaboration to develop sports science products, which led Professor Hsiang to apply LPS technology to player movement analysis \u2014 the athlete tracking system was born.<\/p>

The research team now works closely with the NTNU women\u2019s basketball team with the installation of four tracking units at the Gongguan campus court. Each player wears a sensor, which transmits real-time data to indoor base stations during matches. The LPS system then allows coaches to assess players\u2019 physical load and determine whether their condition or performance has declined or improved.<\/p>

Coach Liang Chia-Yin adds that beyond official games, the team plays one to two friendly matches every two weeks, and the tracking data from these games can help monitor player fatigue and fine-tune regular training intensity.<\/p>

Refined Through Repeated Trials to Ensure Accurate Data Collection<\/strong><\/p>

The sensor is about the size of an index finger, but attaching it to players posed many challenges.<\/p>

Initially, the tracker was placed at the waist, but collisions during movement caused signal delays or tracking issues. Hiding it in the undergarments led to discomfort. After extensive testing, the team found out that the signals are the most stable when they\u2019re attach to the shoulders. Special pockets were sewn into the jerseys at the shoulder area to hold the trackers \u2014 ensuring optimal function without affecting performance.<\/p>

Coach Liang stated that while current trackers only capture player data, important ball-related metrics \u2014 such as passing speed and shooting trajectory \u2014 also matter. The team is now exploring how to embed sensors in the basketball itself, which could further refine LPS applications once real-world tests are completed in the near future.<\/p>

The LPS system is currently used in indoor sports, such as basketball, volleyball, badminton, tennis \u2014 and in outdoor sports like American football. Professor Hsiang also mentioned about future applications of LPS in factory layout and logistics flow, or even in public health. Though still in early development, the fusion of sports and science has already proven capable of delivering impressive results.<\/p>
