Lex completed his BSc in Sport and Exercise Science at Exeter University and graduated with First Class honours in 2006. He then went on to complete his PhD at Exeter University in 2010. During this time he worked as a Graduate Teaching Assistant and completed his BASES supervised experience programme in exercise physiology scientific support.
Lex went from his PhD to work as a Lecturer at the University of Bedfordshire, before joining the University of Kent in 2011, where he is now a Senior Lecturer and Director of Studies for the Sport and Exercise Science Programme. Lex is a regular publisher in some of the leading sport and exercise science journals and has won external grant income from Maxinutrition, UEFA, The Arthritic Association and East Kent NHS Foundation Trust, totalling over £250,000. He also supervises several PhD student as works as a Reviewer for a number of journals.
His current research interests are in the role of exercise-induced pain on fatigue and pacing, and the use of transcranial direct current stimulation in sport. In his spare time Lex is a keen athlete and cook.
Research InterestsLex's principal research interests are focused on the limiting effect of pain on exercise, and the role of the brain in regulation of exercise intensity and endurance performance.He publishes frequently in these areas, presents his research in the UK and internationally and has been featured on BBC Horizon, NBC Today and Stade 2. Lex currently supervises several PhD students, and is an active member for the School’s Endurance Research Group (ERG) and Health Research Group
I will be on Academic Study Leave between September 2018 and August 2019.

Available at: https://doi.org/10.1016/j.brs.2018.12.227.Background: Transcranial direct current stimulation (tDCS) has been used to improve exercise performance, though the protocols used, and results found are mixed. Objective: We aimed to analyze the effect of tDCS on improving exercise performance. Methods: A systematic search was performed on the following databases, until December 2017: PubMed/MEDLINE, Embase, Web of Science, SCOPUS, and SportDiscus. Full-text articles that used tDCS for exercise performance improvement in adults were included. We compared the effect of anodal (anode near nominal target) and cathodal (cathode near nominal target) tDCS to a sham/control condition on the outcome measure (performance in isometric, isokinetic or dynamic strength exercise and whole-body exercise). Results: 22 studies (393 participants) were included in the qualitative synthesis and 11 studies (236 participants) in the meta-analysis. The primary motor cortex (M1) was the main nominal tDCS target (n = 16; 72.5%). A significant effect favoring anodal tDCS (a-tDCS) applied before exercise over M1 was found on cycling time to exhaustion (mean difference = 93.41 s; 95%CI = 27.39 s to 159.43 s) but this result was strongly influenced by one study (weight = 84%), no effect was found for cathodal tDCS (c-tDCS). No significant effect was found for a-tDCS applied on M1 before or during exercise on isometric muscle strength of the upper or lower limbs. Studies regarding a-tDCS over M1 on isokinetic muscle strength presented mixed results. Individual results of studies using a-tDCS applied over the prefrontal and motor cortices either before or during dynamic muscle strength testing showed positive results, but performing meta-analysis was not possible. Conclusion: For the protocols tested, a-tDCS but not c-tDCS vs. sham over M1 improved exercise performance in cycling only. However, this result was driven by a single study, which when removed was no longer significant. Further well-controlled studies with larger sample sizes and broader exploration of the tDCS montages and doses are warranted.

Psychology of Sport & Exercise [Online]. Available at: https://doi.org/10.1016/j.psychsport.2018.07.004.Objectives: Past research has shown that Virtual Reality (VR) is an effective method for reducing the perception of pain and effort associated with exercise. As pain and effort are subjective feelings, they are influenced by a variety of psychological factors, including one's awareness of internal body sensations, known as Private Body Consciousness (PBC). The goal of the present study was to investigate whether the effectiveness of VR in reducing the feeling of exercise pain and effort is moderated by PBC. Design and Methods: Eighty participants were recruited to this study and were randomly assigned to a VR or a non-VR control group. All participants were required to maintain a 20% 1RM isometric bicep curl, whilst reporting ratings of pain intensity and perception of effort. Participants in the VR group completed the isometric bicep curl task whilst wearing a VR device which simulated an exercising environment. Participants in the non-VR group completed a conventional isometric bicep curl exercise without VR. Participants' heart rate was continuously monitored along with time to exhaustion. A questionnaire was used to assess PBC. Results: Participants in the VR group reported significantly lower pain and effort and exhibited longer time to exhaustion compared to the non-VR group. Notably, PBC had no effect on these measures and did not interact with the VR manipulation. Conclusions: Results verified that VR during exercise could reduce negative sensations associated with exercise regardless of the levels of PBC.
