The influence of cycling intensity upon cognitive response during inferred practice and competition Conditions
Journal of sports sciences, 2016Co-Authors: Michael J. Duncan, Neil D. Clarke, Martin Cox, Mike SmithAbstract:ABSTRACTIn many sport and exercise situations, cognitive performance is required under Conditions of high physiological load and high cognitive anxiety. However, few studies have assessed all these components in situ. The current study sought to address this issue. Fourteen adults (9 males, 5 females) completed 2 incremental exercise trials (perceived competition or perceived practice) in a counterbalanced order. Cognitive performance, via a test of visual discrimination, rating of perceived exertion (RPE), heart rate (HR), blood lactate (Bla), and anxiety scores, was recorded at rest, 70% and 90% . Visual discrimination response times were faster at rest compared to 70% (P = 0.001) and 90% (P = 0.002) and at 70% compared to 90% (P = 0.04) in the Competitive Condition. HR post-instructions (P = 0.0001), at 70% (P = 0.001) and 90% (P = 0.0001), was significantly higher in competition compared to practice. RPE was higher in the Competitive Condition compared to the practice Condition (P = 0.023). Cognitive ...

sex differences in autonomic response and situational appraisal of a Competitive situation in young adults
Biological Psychology, 2017Co-Authors: Diana Abadtortosa, Adrian Alacreucrespo, Raquel Costa, Alicia Salvador, Miguel Angel SerranoAbstract:Abstract Competition is a social stressor capable of eliciting physiological responses modulated by the outcome. The main objective of this study was to analyze the psychophysiological changes associated with competition and its outcome in men and women, taking into account the role of situational appraisal. To this end, 112 young people (46 men and 66 women) participated in a laboratory task in a Competitive or non-Competitive Condition, while Blood Pressure (BP), Heart Rate Variability (HRV), and Skin Conductance (SC) responses were measured. Our results indicate that competition elicits higher systolic blood pressure (SBP) than a non-Competitive task; in addition, winners presented a greater R-R decrease from baseline to task, greater R-R Recovery, and lower frustration and external attribution than losers. Regarding sex, men perceived their opponent’s capacity to be lower and their own capacity to be greater than women did, and they also showed higher R-R decreases and lower SC increases. In conclusion, we found a complex pattern of different psychophysiological responses to competition associated with outcome and sex in a laboratory competition. This result could be related to the use of more passive or active coping strategies.

(DP 1997-06) A Theoretical Derivation of the Laffer Curve and the Effect of the Tax on Wage and Employment
2010Co-Authors: Casimiro V. MirandaAbstract:The Laffer curve showing tax revenue as a function of the tax on the prevailing money wage is derived from the aggregate supply of labor function. Consequently, the possible trade-off between tax revenue and employment (or total output) is considered. Then the tax is shown to result in wage rigidity downward even under Competitive Condition. Some policy implications and relevant theoretical issues are noted.
