Investigation of real time and post-match data relationships of wearable GPS systems

Abstract

The aim of this study is to compare the data obtained by using the real time analysis (RTA) and post competition analysis (PCA) of the Polar Team Pro GPS. The number of participants in this study was 20 football players who play in the Amateur League (23 ± 4 years old, 173.75 ± 8 height, 87 ± 11.8 kg). The participants wore GPS systems during three matches, and their data of the distance covered (> 6.99 km/hr, 7.00 to 12.99 km/h, 13.00 to 17.99 km/h, >18.00 km/h) and heart rates (%HRmax 80 to 84, %HRmax 85 to 89, %HRmax 90 to 94, %HRmax 95 to 100, HR mean beats/min) is recorded as RTA and PCA. The Pearson correlation test is used in order to determine the level of the relationship between the measurements of the RTA and the PCA. When evaluating the scatter plots, simple linear regression analysis is performed. According to the results of the analysis of the level of the relationship between the measurements of the RTA and PCA, there is none concerning the parameters of the distance covered and the heart rate. Within these findings, the Real-time and post-competition data of the Polar Team Pro GPS system shows that it can be used by sports’ scientists and coaches for tracking internal and external loads.
