1 TRACKING THROUGH ULTRA WIDE BAND TECH Xavi Reche Royo, Msc Area of sport performance FCB (Tracking monitoring)
2 TRACKING HISTORY IN FCB TEAMWORK OUTDOOR vs INDOOR VALIDITY & RELIABILITY FCB VIEW 2
3 TRACKING MONITORING HISTORY IN FCB Beginnings Soccer teams 1st Soccer team just with few devices Added until U17 Indoor tracking Unique system All 1st teams begins to track their players Indoor teamwork Actually: Tracking monitoring TEAMWORK All the club with the same company, but not the same location system 3
4 TEAMWORK Outdoor sports Indoor sports 1st Soccer team (M) 1st Soccer team (F) 2nd Soccer team (M) U18 Soccer team (M) U17 Soccer team (M) U16 Soccer team (M) Youth Soccer academy (M) 1st Basketball team (M) 1st Handball team (M) 1st Futsal team (M) 1st Roller hockey team (M) 2nd Basketball team (M) 4

8 OUTDOOR VS INDOOR : Isidor Isaac Rabi Nobel laureate in physics. Invented the magnetic resonance, lead to the creation of the Atomic clock, the precise time pieces that form the basis of satellite navigation 8
9 OUTDOOR VS INDOOR - The precise measurement of atomic clock -> calculation of the length of time it takes a radio signal to travel from satellite GPS receiver on earth 9
10 OUTDOOR VS INDOOR What s the difference? LPS vs GPS/GNSS Local Positioning System Global Positioning System 10
11 OUTDOOR VS INDOOR LPS vs GPS/GNSS 11
12 OUTDOOR vs INDOOR There ISN T ONLY Positioning DATA POSITIONING DERIVED - Position (x,y) - Distance - Velocity - Acceleration DATA INERTIAL SENSORS DERIVED - Accelerations - Angular movement & speed - Elevation - ANT+ devices connected - Don t need positioning!!! 12

14 VALIDITY & RELIABILITY (Scott, Scott & Kelly, 2016) 14
15 VALIDITY & RELIABILITY (Scott, Scott & Kelly, 2016) 15
16 VALIDITY & RELIABILITY The validity and inter-unit reliability of 10 Hz GPS for the measurement of instantaneous velocity has been shown to be inversely related to acceleration (Akenhead, et al., 2013) 16
17 VALIDITY & RELIABILITY Poor level of intra-model reliability for very high intensity running (Coutts & Duffield, 2008) 17
18 VALIDITY & RELIABILITY To eliminate inter-unit variation, GPS devices should not be used interchangeably X (Akenhead, et al., 2013) Player A Player B 18
19 VALIDITY & RELIABILITY - 1 to 5 Hz GPS have limitations during short distance Hz GPS seems to be the better frequency with no difference with 15 Hz. - But, few studies with 15 Hz that can explain that (Scott, Scott & Kelly, 2016) 19

32 REAL LOAD FCB VIEW For decades, the monitoring of movements developed by athletes during training or competition have interested sport scientists. (Carling et al. 2008; Castellano & Casamichana 2014; Lieberman et al. 2002) 32
33 REAL LOAD FCB VIEW External load & Internal load Caused by the activity and competition Set of biological and psychological demands What the player does What the player feel (Badillo, 1995) 33
34 FCB VIEW (Montgomery, Pyne & Minahan, 2010) 34
35 FCB VIEW not assume a linear dose-response between the external training load (detected by accelerometry) and the player s internal training load during basketball-specific activities (Scanlan, et al., 2014) 35
