And Behavior

Summary Although sport can promote moral values and prosocial behavior in youth, numerous research shows that sports engagement alone does not guarantee that outcome. Instead of striving for fair-play and sport excellence which not exclude justness, solidarity and moral integrity, contemporary sport frequently follows the Lombardian ethic, where „winning isn’t everything, it’s the only thing”. Moral pause or bracketed morality, as described in sport, refers to the phenomenon of tolerance and acceptance of aggressive behavior or cheating, that will be morally condemned outside sports arenas. Accordingly, lower levels of moral reasoning and behavior have been identified in athletes and non-athletes in the sports-related situation in comparison to other life situations; in athletes when compared to non-athletes, in more experienced athletes, high-level athletes, team-sport athletes, and male athletes. Moral reasoning and behavior of athletes are influenced by contextual and personal factors, with coaches having a particularly important role to play. The positive influence of sport on the moral development of athletes might be related to pre-service and in-service education of coaches how to develop adequate moral atmosphere, and how to plan for moral decision-making as an integral part of everyday practice.

The article presents results of evaluating efficiency of special cooling liquid influence on heat state of athletes at high temperatures. The study covered 7 male athletes of cyclic sports, with sport rank at least 1 adult, average age 19.29±1.80 years. All the athletes underwent double examination including: anamnesis and complaints records, doctor’s examination, subjective evaluation of heat sensations, weight measurements, thermometry (tympanic, sublingual, rectal and skin (in 5 points)), ergospirometric stress testing. Changes in the athletes’ heat state were evaluated via dynamics of weighted average skin temperature and rectal temperature. Moreover, subjective evaluation of heat sensations was considered. Efficiency of the cooling liquid was assessed via dynamics of exercises performance time, maximal oxygen consumption and anaerobic metabolism threshold. The cooling liquid use appeared to be expedientin sport teams of summer sports for specific exertion after individual tests for adverse allergic reactions.

Summary Data

Moderate endurance training is known to improve cardiovascular risk factors, and prolongs life expectancy. On the other hand, there has been some discussion whether “too much” exercise might have a contrarious effect by accelerating coronary atherosclerosis. The goal of this review was to evaluate the current literature on the effects of long-term vigorous endurance training on the coronary vasculature. In summary, data point to an increased calcium score, and a higher burden of atherosclerotic plaque in male athletes compared to sedentary controls. However, the plaques found in athletes were more prone to be calcified. The pathogenesis and clinical relevance of this athlete coronary artery disease phenotype remains incompletely understood and represents an area of important future work.

This study was conducted to investigate the sub-scales of sports instructions of elite athletes with hearing impairment or hearing loss due to different reasons. A total of 173 hearing-impaired athletes constituted of 54 female and 119 male athletes who are active national team athletes in the age range of 15-25 years. The study was conducted based on Self Determination Theory of Deci and Ryan [9] and on the developed Sports Motivation Scale, Pelletier et al. [24] Kazak [18] applied the validity and reliability of the scale for Turkish athletes. Accordingly, since the p_values calculated for the inner motivation sub-scale and its sub-scales are less than the value of α = .05 which is taken as the level of significance, there is a statistically significant difference in the average scores of the hearing-impaired athletes in their internal motivations and sub-scales. According to gender and educational status, there was no difference in the motivation of the hearing-impaired athletes. According to the age variable, it was seen that older athletes had more external connections. Considering the general motivation scores, the athletes in tennis and swimming were less motivated than others. Elite hearing-impaired athletes are affected by both internal and external impulses. However, internal motivation scores are higher than the external. Internal motivation scores are seen as the lowest in the branch swimming area.

Heavy Resistance Exercise

We examined the effects of androstenedione supplementation on the hormonal profile of 10 males and its interaction with resistance exercise. Baseline testosterone, luteinizing hormone, estradiol, and androstenedione concentrations were established by venous sampling at 3 hr intervals over 24 hr. Subjects ingested 200 mg of androstenedione daily for 2 days, with second and third day blood samples. Two weeks later, they ingested androstenedione or a placebo for 2 days, in a double-blind, cross-over design. On day 2, they performed heavy resistance exercise with blood sampled before, after, and 90 min post. The supplement elevated plasma androstenedione 2-3-fold and luteinizing hormone ∼70% but did not alter testosterone concentration. Exercise elevated testosterone, with no difference between conditions. Exercise in the supplemented condition significantly elevated plasma estradiol by ∼83% for 90 min. Androstenedione supplementation, thus, is unlikely to provide male athletes with any anabolic benefit and, with heavy resistance exercise, elevates estrogen. Key Words: testosterone, luteinizing hormone, estradiol, fluid shifts, resistance exercise
