Effect of creatine supplementation and sleep deprivation, with mild exercise, on cognitive and psychomotor performance, mood state, and plasma concentrations of catecholamines and cortisolT McMorris
Centre for Sports Science and Medicine, University College Chichester, College Lane, Chichester, West Sussex PO19 6PE, UK
Psychopharmacology (Berl) 185:93-103. 2006..Therefore, creatine supplementation should lessen the negative effects of sleep deprivation...- Performance of a psychomotor skill following rest, exercise at the plasma epinephrine threshold and maximal intensity exerciseT McMorris
Centre for Sports Science and Medicine, University College Chichester, West Sussex, United Kingdom
Percept Mot Skills 91:553-62. 2000..No significant effects of exercise were shown for any of the variables. The need for further research using more complex skill tests and the use of discontinuous exercise protocols, rather than continuous ones, is recommended... - Incremental exercise, plasma concentrations of catecholamines, reaction time, and motor time during performance of a noncompatible choice response time taskTerry McMorris
Centre for Sports Science and Medicine, University College Chichester, West Sussex, UK
Percept Mot Skills 97:590-604. 2003..Only power output was a significant predictor of movement time (R2 = .24). There was little support for the notion that peripheral concentrations of catecholamines directly induce a central nervous system response... 
Effect of incremental exercise on initiation and movement times in a choice response, whole body psychomotor taskT McMorris
University College Chichester, Chichester, W Sussex, UK
Br J Sports Med 39:537-41. 2005..To examine how exercise at moderate and maximal intensities affects performance on a choice response time, whole body psychomotor task...- Supra-maximal effort and reaction and movement times in a non-compatible response time taskT McMorris
Centre for Sports Science and Medicine, University College Chichester, West Sussex, UK
J Sports Med Phys Fitness 45:127-33. 2005..The primary purpose of this study was to examine the effect of attempting to exercise supra-maximally on reaction time and movement time in a non-compatible response time task... - Heat stress, plasma concentrations of adrenaline, noradrenaline, 5-hydroxytryptamine and cortisol, mood state and cognitive performanceTerry McMorris
Centre for Sports Science and Medicine, University College Chichester, College Lane, Chichester, West Sussex PO19 6PE, UK
Int J Psychophysiol 61:204-15. 2006.... - Warm-up prior to undertaking a dynamic psychomotor task: does it aid performance?T McMorris
Centre for Sports Science and Medicine, University College Chichester, Chichester, UK
J Sports Med Phys Fitness 46:328-34. 2006..The purpose of this study was to examine the effect of differing types of warm-up on the performance of a psychomotor skill that required quick reaction and movement times (MTs), and whole-body co-ordination... - Creatine supplementation, sleep deprivation, cortisol, melatonin and behaviorT McMorris
Centre for Sports Science and Medicine, University of Chichester, College Lane, Chichester, West Sussex PO19 6PE, UK
Physiol Behav 90:21-8. 2007..01) lower than in the other conditions. It was concluded that, during sleep deprivation with moderate-intensity exercise, creatine supplementation only affects performance of complex central executive tasks... 
A test of the catecholamines hypothesis for an acute exercise-cognition interactionT McMorris
University of Chichester, College Lane, Chichester, West Sussex PO19 6PE, UK
Pharmacol Biochem Behav 89:106-15. 2008..The regression data suggest that there is some relationship between exercise, catecholamines concentrations and cognition...- The measurement of plasma catecholamine and lactate thresholds: a comparison of methodsT McMorris
Centre for Sports Science and Medicine, University College Chichester, West Sussex, UK
Eur J Appl Physiol 82:262-7. 2000..63). It was concluded that the algorithmic method was less powerful than the other two methods, and that Th1a, ThA and ThNA are not highly correlated... - Perceived anxiety and plasma cortisol concentrations following rock climbing with differing safety rope protocolsC I Hodgson
University of Chichester, College Lane, Chichester PO19 6PE, UK
Br J Sports Med 43:531-5. 2009..To examine how different safety rope protocols impact on subjective anxiety and self-confidence levels and plasma cortisol concentrations and the relationship between subjective states and cortisol during rock climbing... - Creatine supplementation and cognitive performance in elderly individualsTerry McMorris
School of Sport, Exercise and Health Sciences, University of Chichester, College Lane, Chichester, West Sussex PO19 6PE, UK
Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 14:517-28. 2007..Participants were retested at the end of each week. Results showed a significant effect of creatine supplementation on all tasks except backward number recall. It was concluded that creatine supplementation aids cognition in the elderly... - Short-duration, high-intensity exercise and performance of a sports-specific skill: a preliminary studyTerry McMorris
Centre for Sports Science and Medicine, University of Chichester, College Lane, Chichester, West Sussex PO19 6PE, United Kingdom
Percept Mot Skills 105:523-30. 2007..It was concluded that short-duration, high-intensity exercise has a negative effect on accuracy in a sports-specific task that requires both perceptual judgment and motor control...
