..The very limited effect on accuracy may be due to the failure to choose tests which are complex enough to measure exercise-induced changes in accuracy of performance...

..There was no support for a speed-accuracy trade-off. It was argued that exercise-induced increases in brain concentrations of catecholamines result in faster processing but increases in neural noise may negatively affect accuracy...

..It was concluded that exercise must be at a high intensity to affect performance on the flanker task. Both the SAS and HPAA appear to play a role in the exercise-cognition interaction...

..We hypothesized that subjects using suspension seats would demonstrate better cognitive performance, lower perceptions of exertion, fatigue, and sleepiness, and lower salivary concentrations of cortisol than those using fixed seats...

..The regression data suggest that there is some relationship between exercise, catecholamines concentrations and cognition...

..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...

..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...

..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...

..Therefore, creatine supplementation should lessen the negative effects of sleep deprivation...

..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...

..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...

..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...

..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...

....

..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...

..response level conflict) nor on the amount of cognitive control engaged in the task (congruent vs. incongruent trials). Distributional RT analyses did not highlight any sign of impairment in the efficiency of cognitive control...

..To examine how exercise at moderate and maximal intensities affects performance on a choice response time, whole body psychomotor task...

..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...

..Beneficial effects of exercise remain present on both response execution and response inhibition performance for up to 52min after exercise cessation...

..Learners with greater field independence may have an advantage when acquiring sport skills that require cognitive restructuring and a strong reliance on kinesthetic and proprioceptive feedback...

..The present findings suggest that acute moderate exercise differently affects some specific aspects of cognitive functions...
