“…To carry out a comprehensive accuracy assessment of EPTS, comparisons need to be made in three different categories because in each category different problems could occur and different accuracy demands have to be met [18]. While several studies have assessed the validity and reliability of GPS [5,14,27] and the VID [12] technologies to track player movement patterns with systematic reviews, to date, no study has carried out this type of analysis with respect to LPS technology. Thus, the aim of the review was to summarize the evidence about the validity and reliability of LPS technology to measure movement patterns in outdoor and indoor environments.…”

“…Moreover, LPS and GPS based sensors are included in a Wireless Body Sensor Network [2][3][4], which is a group of wearable sensor nodes and which can include other types of sensors (e.g., microelectromechanical sensors). These systems allow the quantification of kinematic [5,6], physiological [7], neuromuscular [5] and tactical variables [8][9][10][11] to optimize the training process and performance in competition [5,[12][13][14][15]. GPS and VID have been widely used with a very similar frequency to track player movement patterns, but this cannot be interpreted as equality over time [1,16].…”

Accuracy and Reliability of Local Positioning Systems for Measuring Sport Movement Patterns in Stadium-Scale: A Systematic Review

The use of valid, accurate and reliable systems is decisive for ensuring the data collection and correct interpretation of the values. Several studies have reviewed these aspects on the measurement of movement patterns by high-definition cameras (VID) and Global Positioning Systems (GPS) but not by Local Positioning Systems (LPS). Thus, the aim of the review was to summarize the evidence about the validity and reliability of LPS technology to measure movement patterns at human level in outdoor and indoor stadium-scale. The authors systematically searched three electronic databases (PubMed, Web of Science and SPORTDiscus) to extract studies published before 21 October 2019. A Boolean search phrase was created to include sport (population; 8 keywords), search terms relevant to intervention technology (intervention technology; 6 keywords) and measure outcomes of the technology (outcomes; 7 keywords). From the 62 articles found, 16 were included in the qualitative synthesis. This systematic review revealed that the tested LPS systems proved to be valid and accurate in determining the position and estimating distances and speeds, although they were not valid or their accuracy decreased when measuring instantaneous speed, peak accelerations or decelerations or monitoring particular conditions (e.g., changes of direction, turns). Considering the variability levels, the included studies showed that LPS provide a reliable way to measure distance variables and athletes’ average speed.

“…In addition, the distance of high-speed running efforts (i.e., sprints, accelerations, and decelerations) characterize the specifics of the game or the training session (Martín-García et al, 2018). For these GPS parameters, the average, the minimum, and the maximum values should be considered for analyses (Rago et al, 2019b). The speed or acceleration threshold (e.g., high speed running between 19.8 and 24.8 km/h) has been arbitrarily defined and is equal for all players (Rago et al, 2019b).…”

“…In the "real world" of professional soccer, it is not always possible to evaluate players' capacities to quantify the training load using individualized GPS parameters (Carling et al, 2018). In summary, it can be recommended to determine relevant GPS parameters, based on arbitrary or individualized thresholds, as they will fit well with the training programs and their foundations (Rago et al, 2019b).…”

The aim of this study was to compare the exercise demands between two intermittent small-sided games (SSGs) and their temporal changes throughout SSGs repetitions, while controlling for total exercise duration. Exercise demands were recorded using wearable 10-Hz global positioning system technology with a 100-Hz accelerometer embedded and heart rate (HR) monitors in eight U17 male professional football players (age = 16.3 ± 0.5 years old) during two 18-min 4v4 plus goalkeepers SSGs based on long bouts (LB; 3 × 6 min) and short bouts (SB; 6 × 3 min) separated for 2-min rest. Total duration was 18 min, pitch dimensions were (length × width) 24 × 17 m and relative space per players was 51 m 2 . During LB, higher total distance, accelerations > 2 m s −2 , decelerations < − 2 m s −2 (Dec2), peak HR (HR peak ) and mean HR (HR mean ) were observed (ES = 0.5-7.4). During LB, explosive distance (> 1.2 m s −2 ) and Dec2 decreased from the 1st toward 3rd bout (ES = 0.6-1.5). During SB, HR peak and HR mean increased in the 2nd and 3rd (ES = 1.7-3.2) and then decreased in the 4th, 5th and 6th bout (ES = 0.7-3.5). The LB-based SSGs seem to produce greater physical and physiological demands than SB. However, SB induced greater fluctuations in HR while ensuring work rate maintenance across bouts.
