#1. Improving predictor selection for injury modelling methods in male footballers
Fraser Philp, Ahmad Al-Shallaw, Theocharis Kyriacou, Dimitra Blana, Anand Pandyan
This study evaluated whether combining existing methods of Elastic net for zero-inflated Poisson and zero-inflated Poisson regression methods could improve real life applicability of injury prediction models in football. Predictor selection and model development was conducted on a pre-existing dataset, from a single English football teams’ 2015/2016 season. The Elastic Net for zero-inflated Poisson penalty method was successful shrinking the total number of predictors in the presence of high levels of multicollinearity. It was additionally identified that easily measurable data, i.e. mass and body fat content, training type, duration and surface, fitness levels, normalised period of “no-play” and time in competition could contribute to the probability of acquiring a time loss injury. Furthermore, prolonged series of match play and increased in-season injury reduced the probability of not sustaining an injury. For predictor selection, the Elastic net for zero-inflated Poisson penalised method in combination with the use of ZIP...

#2. No effect of tDCS of the primary motor cortex on isometric exercise performance or perceived fatigue
James Wrightson, Rosemary Twomey, Guillaume Y. Millet
Introduction: Anodal transcranial direct current stimulation (tDCS) of the primary motor cortex has been reported to improve isometric exercise performance without changing corticospinal excitability. One possible cause for this may be the previous use of relatively high (2 mA) current intensities, which have inconsistent effects on corticospinal excitability. The present pre-registered study aimed to replicate previously reported ergogenic effects of 2 mA tDCS, and examine whether 1 mA anodal tDCS both improved isometric exercise performance and perceived fatigue, and more reliably altered corticospinal excitability. Methods: On three separate occasions, participants performed a sustained submaximal isometric knee extension until failure after receiving either 1 mA, 2mA or sham anodal tDCS. Corticospinal excitability of the knee extensors was measured using transcranial magnetic stimulation immediately before and after tDCS. Rating of fatigue was recorded throughout the isometric exercise. Results: Neither 1 nor 2 mA tDCS...
