Understanding the presence of mental fatigue in English academy soccer players (2020)
Journal Article
Thompson, C. J., Noon, M., Towlson, C., Perry, J., Coutts, A. J., Harper, L. D., …Meyer, T. (2020). Understanding the presence of mental fatigue in English academy soccer players. Journal of sports sciences, 38(13), 1524-1530. https://doi.org/10.1080/02640414.2020.1746597

Research has demonstrated that induced mental fatigue impairs soccer-specific technical, tactical and physical performance in soccer players. The findings are limited by the lack of elite players and low ecological validity of the tasks used to induc...

The validity of external:internal training load ratios in rested and fatigued soccer players (2018)
Journal Article
Akubat, I., Barrett, S., Sagarra, M. L., & Abt, G. (2018). The validity of external:internal training load ratios in rested and fatigued soccer players. Sports open access journal, 6(2), 44. https://doi.org/10.3390/sports6020044

Purpose: To examine the relationship of external:internal training load ratios with fitness and assess the impact of fatigue. Method: Ten soccer players performed a lactate threshold test followed by two soccer simulations (BEAST90mod) 48 h apart. Re...

The within-match patterns of locomotor efficiency during professional soccer match play: implications for injury risk? (2016)
Journal Article
Barrett, S., Midgley, A., Reeves, M., Joel, T., Franklin, E., Heyworth, R., …Lovell, R. (2016). The within-match patterns of locomotor efficiency during professional soccer match play: implications for injury risk?. Journal of science and medicine in sport / Sports Medicine Australia, 19(10), 810-815 . https://doi.org/10.1016/j.jsams.2015.12.514

Objectives The principle aim of the current study was to examine within-match patterns of locomotor efficiency in professional soccer, determined as the ratio between tri-axial accelerometer data (PlayerLoad™) and locomotor activities. Between match... Read More about The within-match patterns of locomotor efficiency during professional soccer match play: implications for injury risk?.

Within-match PlayerLoad™ patterns during a simulated soccer match (SAFT90): potential implications for unit positioning and fatigue management (2016)
Journal Article

Within-match PlayerLoad™ patterns during a simulated soccer match (SAFT90): potential implications for unit positioning and fatigue management. International journal of sports physiology and performance : IJSPP, 11(1), 135-140. https://doi.org/10.1123/ijspp.2014-0582

© 2016 Human Kinetics, Inc. Purpose: To assess the acute alterations in triaxial accelerometry (PlayerLoad [PL VM ]) and its individual axial planes (anteroposterior PlayerLoad [PL AP ], mediolateral PlayerLoad [PL ML ], and vertical PlayerLoad [PL V...

Individualisation of time-motion analysis : a method comparison and case report series (2014)
Journal Article
Hunter, F., Bray, J., Towlson, C., Smith, M., Barrett, S., Madden, J., …Lovell, R. (2015). Individualisation of time-motion analysis : a method comparison and case report series. International journal of sports medicine, 36(1), 41-48. https://doi.org/10.1055/s-0034-1384547

© Georg Thieme Verlag KG. This study compared the intensity distribution of time-motion analysis data, when speed zones were categorized by different methods. 12 U18 players undertook a routine battery of laboratory- and field-based assessments to de...

Integrating the internal and external training loads in soccer (2014)
Journal Article
Akubat, I., Barrett, S., & Abt, G. (2014). Integrating the internal and external training loads in soccer. International journal of sports physiology and performance : IJSPP, 9(3), 457-462. https://doi.org/10.1123/ijspp.2012-0347

Purpose: This study aimed to assess the relationships of fitness in soccer players with a novel integration of internal and external training load (TL). Design: Ten amateur soccer players performed a lactate threshold (LT) test followed by a soc... Read More about Integrating the internal and external training loads in soccer.
