nicotine/fatigue

OBJECTIVE Message fatigue, a phenomenon of being tired of repeated exposure to messages promoting the same health behavior, may reduce the effectiveness of anti-tobacco messages, such as warning labels. As an initial step towards understanding the phenomenon, we examined predictors of anti-tobacco

OBJECTIVE The need to understand potential precipitants of smoking relapse is exemplified by relapse rates as high as 95%. The Self-Control Strength model, which proposes that self-control is dependent upon limited resources and susceptible to fatigue, may offer insight into relapse processes. The

Sixteen smokers completed a sustained attention task, were randomly assigned to either continue smoking or abstain for 24 h, and were retested. Eight nonsmokers served as a control group. Abstinence increased the variability in responding. Abstinence also appeared to impair the ability to inhibit

UNASSIGNED Smokeless tobacco is widely used by athletes to enhance performance. Nicotine is a central nervous system stimulant and acts on cardiocirculatory and metabolic systems, involving tissue blood flow and circulatory vasoreactivity. The aim of this study was to investigate the effects of the

BACKGROUND Nicotine use amongst athletes is high and increasing, especially team sports, yet the limited previous studies investigating the performance consequences of this behaviour have not examined the effects of the principal active ingredient, nicotine, per se. Therefore, we determined whether

The objective of this study was to evaluate the independent associations between nausea, vomiting, fatigue and health-related quality of life of women in early pregnancy in the Generation R study, which is a prospective mother and child cohort. Analyses were based on 5079 women in early pregnancy in

Rats were chronically treated with nicotine via subcutaneous injections up to a dose 6 mg/kg/day during 2-3 weeks. After this period, resting membrane potential and action potentials of muscle fibres as well as isometric twitch and tetanic (20 s(-1) and 50(-1)) contractions of isolated rat diaphragm

Psychomotor stimulant drugs such as caffeine, nicotine, amphetamine and cocaine, have been shown to improve vigilance in man under conditions of fatigue. Nicotine has also been shown to improve performance in some cognitive tests in patients with Alzheimer's disease. In rodents these drugs increase

The authors investigated the relationship between household environmental tobacco smoke (ETS) exposure and prevalence of respiratory symptoms and diseases as well as absenteeism related to respiratory illness in schoolchildren. The study sample consisted of 1,074 children aged 7-11 years from three

The association between obsessive-compulsive (OC) symptomatology and smoking is poorly understood, particularly in African Americans-a group subject to smoking- and OC-related health disparities. In a non-clinical sample of 253 African American smokers, we tested the negative reinforcement model of
