Introduction.The aim of the study was to determine the age, level of achieving maximum results and growth of reaction time dynamics. Materials and methods. The study included 567 males of age between 7 and 22 years. Study materials included the results of simple reaction time and complex reaction time during progressive period. Conclusions. Progressive period of results' development lasts until the age of about 17-17.5, then stabilization of the analyzed results was observe. The most dynamic growth of all types of reaction time was observed in the analyzed 7 and 8-year-old boys.

The aim of the study was to assess the relationship between the sense of generalised self-efficacy and the level of prohealth behaviours among Polish and Spanish physical education students. The study was conducted among 499 physical education students (219 Polish and 280 Spanish). The Inventory of Health Behaviours (IZZ) by Z. Juczyński and the Generalised Self-Efficacy Scale (GSES) by R. Schwarzer, M. Jerusalem and Z. Juczyński were used. Among the categories of healthy behaviours included in the Inventory of Health Behaviours (IZZ), the physical education students obtained the highest average results in the area of positive mental attitude (22.26), less in the prohealth practices (20.10) and proper eating habits (19.85), and less again in the area of preventive behaviours (18.97). Statistically significant positive correlations were found between the intensification of the generalised sense of self-efficacy and the levels of positive mental attitude (p = 0.024) and preventive behaviours (p < 0.001). The moderating influence regarding home country on relationships between the generalised sense of self-efficacy and general index of pro-health behaviours (p = 0.024) was also demonstrated; in the case of the Spanish students the level of pro-health behaviours increased, but for the Polish students it decreased.

Purpose. The objective of this study was to determine the level and rate of change of reaction time during the developmental period from early childhood to early adulthood. Polynomial regression analysis was applied to determine the age at which the best reaction time results are achieved. Methods. The study involved 550 females between the ages of 7 and 20 years. Participants completed a computer test measuring simple reaction times to visual and auditory stimuli and choice reaction time during the ontogenetic developmental period. Results. Analysis of the results for age group distinguished two sub-periods of reaction time dynamics: a progressive increase throughout the developmental period followed by a plateau phase. This was evident for all reaction time measures (simple and choice) particularly in the case of that data collected empirically. Conclusions. best reaction times to visual and auditory stimuli were approximately at the age of 17 years. In turn, quickest choice reaction time was approximately one year earlier in life. The most dynamic increase in the results of both simple reaction times was between the age of 7 and 8 years, whereas for choice reaction time this was between 10 and 11 years of age.

The aim of the study was to analyse the relationship between the profile of readiness to change and pro-health behaviours as well as physical activity among students of physical education and other teaching specialisation. The study was carried out among a randomly selected group of teaching specialisation students (464 females and 143 males). In the research, the following were applied: Inventory of Pro-health Behaviours by Z. Juczyński, the IPAQ and the Readiness to Change Questionnaire. Diversification in pro-health behaviours, level of physical activity and selected features of readiness to change among students of teaching specialisations was demonstrated. In the general population, along with the increase in selfconfidence, passion and optimism, the level of health pro-behaviours also increased. Regardless of the type of studies, there were significant positive correlations between the level of physical activity and the degree of passion, optimism and boldness. Among students of other teaching specialisations (apart from physical education), a positive relationship was also noted between physical activity and creativity. Among the students of teaching specialisations, a correlation was demonstrated between the level of pro-health behaviours and physical activity as well as the degree of selected features constituting readiness to change.

The aim of the study was to assess the frequency of consuming particular food groups among regional-level football referees depending on age, refereeing experience and sense of generalised self-efficacy. The study was conducted among agroup of 138 male football referees from the Małopolska and Podkarpacie regions, using the authors’ own questionnaire on food consumption frequency and the Generalised Self-Efficacy Scale (GSES). It was shown that along with the age of the referees, the frequency of consuming fruit (p < 0.001), milk and dairy products with reduced fat content (p < 0.001), poultry and cold-cuts (p < 0.01) as well as nuts (p < 0.001) increased, while the frequency of consuming white cereal products (p < 0.001) and sea fish (p < 0.05) decreased. Along with refereeing experience, the frequency of eating fruit (p < 0.001), milk and dairy products with reduced fat content (p < 0.01), poultry meat and cold-cuts (p = 0.001), nuts (p < 0.001) and alcoholic beverages (p < 0.001) increased, while the frequency of consuming white cereal products (p < 0.001), sea fish (p < 0.05) and sweet carbonated drinks (p < 0.01) decreased. Apositive correlation was found between the intensity of generalised self-efficacy and the frequency of consuming milk and dairy products with reduced fat content (p < 0.01), fermented dairy products (p < 0.01), eggs (p < 0.001) and mineral water (p < 0.001) as well as dry red wine (p < 0.05), and anegative correlation was noted with the frequency of consuming pork (p < 0.05), fast food products (p = 0.001) and sweetened carbonated beverages (p < 0.001). In the examined group of regional-level football referees, there was atendency towards more rational nutrition choices along with age and refereeing experience as well as asense of self-efficacy, while the most explicit trends regarded relationships with the sense of self-efficacy.
