The role of psychological resilience and aggression in injury prevention among martial arts athletes.

Introduction: For martial artists, the ability to manage reactions in the face of adversity and bounce back after a stressful event can have major impact on performance. The scope of the research is to investigate martial artists' level of resilience and aggression (Go-ahead, Foul play, and Assertiveness factors), what is specific to athletes and who have suffered from moderate and/or severe injuries (in terms of resilience and three factors of aggression examined), and test the possibility that a psychological variable under investigation can predict athletes' injury severity.

Materials And Methods: A total sample of 154 athletes from striking combat sports-SC (karate, taekwondo, kickboxing, and boxing), grappling combat sports-GC (judo and BJJ), and mixed martial artists (MMA) participated in the research.

A-trait and risk-taking behavior in predicting injury severity among martial arts athletes.

Introduction: Trait anxiety (A-trait) can be seen as a multiplicative function of the person-situation interaction. Considering risk-taking behavior (R-TB), literature highlights instrumental and stimulating risk. The aim of the research is to investigate the level of A-trait (in physically dangerous conditions and in new, unusual situations) and the level of R-TB (instrumental and stimulating risk) in athletes, and to verify to what extent A-trait and risk-taking behavior predict injury severity.

Stress among nurses from countries variously affected by the COVID-19 pandemic - results collected in Poland and Iran.

Background: Nursing involves numerous stressful situations, such as overwork, night shifts, responsibility for the patients' health, rapid pace of work, emotional demands, contact with suffering individuals, and patients' aggressive behaviors. The SARS-CoV-2 pandemic is an additional demand on the already demanding profession. Thus, the aim of the current study was to assess the character of the relationship between overwork and subjectively experienced stress, taking into account the moderating role of contact with patients and work in facilities dedicated for COVID-19 patients, and the strategies of coping with stress, including resilience, in countries affected by the pandemic to various degrees.

The Human Factor in Maritime Transport: Personality and Aggression Levels of Master Mariners and Navigation Students.

The current study sought to identify groups of navigation students and master mariners (captains) characterized by different constellations of the Big Five personality traits and aggression levels. We hypothesized that master mariners would exhibit the resilient personality type and that navigation students would additionally exhibit personality types other than the resilient (e.g.

Stress dynamics in long-term isolation at sea. A demographic variables model.

The current article describes a naturalistic research programme carried out among fishermen during a 6-month expedition to the southern Atlantic Ocean. Stress levels of 81 participants were measured 4 times during the expedition. Social-demographic variables (age, years of experience at sea, job satisfaction, education, current and childhood place of residence, relationship status) were also included in the analysis.

[The psychological profile of pilots of passenger planes: Analysis of temperamental traits, aggression and risk].

Background: Over the years it has been assumed, that the greater the number of pilot flight hours, the better the development of problem-solving skills among pilots. Research suggests, however, that the problem is more complex than that. Not only one's experience is of importance - temperament, aggression and risk may also affect the decision-making process under stressful conditions.

Adrenaline Instead of Amphetamine-Replacing Psychoactive Substances with Parachute Jumps.

The "Adrenaline Instead of Amphetamine" program was launched by Gdańsk's MONAR association-a center for drug treatment. The purpose of the program was to show some alternatives to using psychoactive substances and to propose replacing these anti-medical behaviors with parachuting. The treatment effectiveness in this center is about 30%, and the program's effectiveness was 80%.

Speech intelligibility in cerebral palsy children attending an art therapy program.

Background: Dysarthia is a common sequela of cerebral palsy (CP), directly affecting both the intelligibility of speech and the child's psycho-social adjustment. Speech therapy focused exclusively on the articulatory organs does not always help CP children to speak more intelligibly. The program of art therapy described here has proven to be helpful for these children.

Application of the high-performance liquid chromatography method with coulometric detection for determination of vitamin B(6) in human plasma and serum.

A reversed-phase high-performance liquid chromatography method (HPLC) with coulometric electrochemical detection has been developed and validated for the simultaneous analysis of pyridoxamine-5'-phosphate (PMP), pyridoxamine (PM), pyridoxal 5'-phosphate (PLP), pyridoxal (PL), pyridoxine (PN) and 4-pyridoxic acid (4-PA) in human plasma and serum. The isocratic separation was achieved on C(18) column (250mmx4.6mm, I.

[Hiperhomocysteinemia in active and passive smokers and the levels of folate and vitamin B6 in plasma].

The increased plasma level of homocysteine have been shown to be the sensitive marker for the folate, vitamin B6 and cobalamins deficiency and an independent risk factor for the cardiovascular disease, neutral tube defects and a potential causal risk factor for neuropsychiatric disorders. The blood and plasma homocysteine levels except for genetic defects are influenced by age, gender, efficiency of detoxication systems, one or more unhealthy lifestyle factors, such as high alcohol consumption, low nutritional intake of vitamins, high coffee consumption, acquired disorders and lack of physical exercise. Many studies confirm that active tobacco smoking and environmental tobacco smoke (ETS) have been significantly associated with hiperhomocysteinemia.

[The influence of tobacco smoking on homocysteine and glutathione levels in biological samples].

The aim of this paper was to examine the effect of tobacco smoking on the level of homocysteine and glutathione in biological samples. The study comprised 30 people, who qualified into two groups--subjects who never smoke the cigarettes (n = 10) and currently smoking (n = 20). Smoking habit were assessed by questionnaire.
