%X PURPOSE: The principle aim of the study was to assess the validity of measuring locomotor activities and PlayerLoad using Real-Time (RT) data collection during soccer training. <br><br>METHODS: Twenty-nine (n=29) English soccer players participated. Each player wore the same MEMS device (S5, Optimeye, CatapultSports, Melbourne, Australia) during twenty-one training sessions (n= 331 data sets) in the 2015/2016 and 2016/2017 season. A Real-Time receiver (TRX, Catapultsports, Melbourne, Australia) was used to collect the locomotor activities and PlayerLoad data in RT and compared with the post-event downloaded (PED) data. PlayerLoad and locomotor activities (total distance covered, TDC; total high speed running distance covered, >5.5m/s, HSR; total sprinting distance covered, >7m/s, SP; maximum velocity, VEL) were analysed. <br><br>RESULTS: Correlations were near perfect for all variables analysed (r=0.98-1.00), with a varied level of noise between RT and PED also (0.3-9.7% CV). <br><br>CONCLUSIONS: Locomotor activities and PlayerLoad can be used both RT and PED concurrently to quantify a players physical output during a training session. Caution should be taken with higher velocity based locomotor activities during RT compared to PED.<p /> <p>Language: en</p>
