Doping in Sport-Attitudes of Physical Trainers Students Regarding the Use of Prohibited Substances Increasing Performance.

BACKGROUND: The popularity of using the advice of a personal trainer is increasing in Poland and currently most gyms offer the possibility of training under the supervision of a professional. Personal trainers present a multifaceted nature into physical activity and become their clients' guides in achieving sporting goals. Physical trainers also work in sports clubs and supervise the training of people professionally involved in sport. AIM: Given the professional role that they play, this article aimed to analyze the knowledge and attitudes of personal trainers towards using prohibited measures to improve performance in sport, as well as counteraction measures. METHODS: The study used a questionnaire created by the authors containing closed, semi-open, and open questions. RESULTS: The results of the presented research indicate that most physical trainers and students educated in this field have a negative attitude towards the use of prohibited measures that increase performance but they noticed that doping was common in sport by 88.51% respondents. In the group of personal trainers, the majority (87.14%) admitted that good results in sport could be achieved without the use of doping. They stated that it was unfair (25%), contrary to the fair play principle-16%, while over 11% indicated this as cheating. Only 6% of people pointed out that it was legally prohibited and 3% that it was harmful. These results show that 10.13% of all respondents believe that the use of doping is a necessity to achieve very good results in sport. CONCLUSIONS: The availability of doping substances is statistically correlated with the question of persuading to use doping in both groups of trainers and students and some people justify the use of doping. The research proved that the personal trainers' level of knowledge on doping is still insufficient.

Aerobic Capacity in Relation to Selected Elements of Body Posture.

BACKGROUND: In the 21st century, with the rapid development of many human life areas, physical activity should be prevalent in health maintenance and promotion. Body posture is a motor habit characteristic of every individual. Its correctness depends on numerous aspects, e.g., physical activity, age, mental state, or eating habits. There are numerous reports in the literature on the impact of physical activity on body posture, correct foot arch development, and the level of aerobic capacity in children and adolescents, but there is a noticeable lack of assessments of these characteristics and their correlations in adults. AIM: To evaluate aerobic capacity in males and females in relation to selected body posture elements. METHODS: The study involved 45 females and 46 males aged 20-21 years. The inclusion criteria involved declared good health and no contraindications. Selected somatic traits, body posture, and physical capacity indicators were determined. RESULTS: Physical capacity shows a significant relationship with body mass in both sexes (female: r = -0.346; p = 0.020; male: r = -0.321; p = 0.030). A significant correlation was observed between aerobic capacity and lean body mass in females (r = -0.428; p = 0.003) and body mass (r = -0.461; p = 0.001) and body fat percentage in males (r = -0.443; p = 0.002). A significant correlation was demonstrated between maximal oxygen uptake and Clarke's angle (r = -0.300; p = 0.045) in females, between maximal oxygen uptake and the loaded area of the right foot (r = -0.247; p = 0.098) in the male group, and between maximal oxygen uptake and spine lateral deviation (r = 0.352; p = 0.018) in females. There was no dimorphism between body posture elements and physical capacity except for the level of foot longitudinal arches, feet loading surface, spine lateral deviation, and the range of spine mobility in the sagittal and frontal planes. Aerobic capacity significantly influenced lean body mass (ß = -0.379; p = 0.007) and spine deviation from the anatomical axis in the frontal plane in females (ß = 0.287; p = 0.039) and body fat percentage in males (ß = -0.443; p = 0.002). CONCLUSIONS: Selected body posture elements demonstrate relationships with physical capacity in both sexes. The results should find wide practical applications, e.g., in promoting a comprehensive assessment of body posture and physical capacity as determinants of health maintenance.
