POSTER ABSTRACTS - THURSDAY, 21 MAY 2015for the aetiological risks associated with periods of short term fixture congestion and thedevelopment of recovery strategies. The interaction of muscular response to soccer-specificactivity, the subsequent reduction in muscular strength, and the perception of muscular sorenesssuggest a biomechanical (as opposed to physiological) focus in recovery.P03.06The influence of fatigue on the external:internal training load ratios in soccerIbrahim Akubat(1), S Barratt(2), M Lapuente(3), G Abt(4)(1) Newman University, Birmingham, UK(2) Hull City AFC, Kingston Upon Hull, UK(3) Bani Yas FC, Abu Dhabi, United Arab Emirates(4) University of Hull,Kingston Upon Hull, UKIn fully rested players, the use of external:internal training load (TL) ratios have shown largerelationships with measures of fitness. However players may not always be in a rested state due totraining and match-play commitments. Therefore this study aimed to examine the TL ratios inrested and fatigued conditions. 10 university-level soccer players underwent a lactate threshold testfrom which internal TL (iTRIMP) was calculated. Players performed a 90 minute soccer simulation(BEAST90mod) on two occasions separated by 48h, during which heart rate and external loadmetrics were collected using a MEMS device (5Hz GPS, 100Hz Accelerometer). Measures ofexternal TL [total distance (TD); high-intensity distance (HID); PlayerLoad (PL); mean metabolicpower (MMP); distance at high metabolic power (HMP)] and iTRIMP were used to calculate theexternal:internal TL ratios. There were non-significant trivial to small decreases in TD (p=0.17;ES=0.32), PL (p=0.43; ES=0.37), MMP (p=0.98 ES=0.008) and HMP (p=0.13; ES=0.48) fromsimulation 1 to 2, whereas a moderate decrease was observed for HID (p=0.01; ES: 0.63). Therewere small to moderate significant increases across the two simulations for TD:iTRIMP (p
