Sport is an important element of self-improvement and professional development of every person and above all of firefighters, since their service involves helping people and saving property in particularly dangerous and often quite extreme conditions. The article is an assessment of the impact of sports on the improvement of fitness, integration and motivation of firefighters in the context of safety during operational activities of State Fire Service units, based on two different environments - the District Headquarters of the State Fire Service in Włoszczowa and the Polish firefighters’ team in firefighting sports. Empirical research was conducted using a survey questionnaire. The results of the research and the formulated conclusions summarize the article.

Sport jest ważnym elementem samodoskonalenia i rozwoju zawodowego każdego człowieka, a przede wszystkim strażaka, gdyż jego służba polega na niesieniu pomocy ludziom i ratowaniu mienia w szczególnie niebezpiecznych i często ekstremalnych warunkach. Artykuł jest oceną wpływu sportu na poprawę sprawności, integrację i motywację strażaków w kontekście bezpieczeństwa podczas działań operacyjnych jednostek Państwowej Straży Pożarnej na przykładzie dwóch różnych środowisk – Komendy Powiatowej Państwowej Straży Pożarnej we Włoszczowej i reprezentacji polskich strażaków w sportach pożarniczych. Badania empiryczne przeprowadzono za pomocą kwestionariusza ankiety. Wyniki badań i sformułowane wnioski podsumowują artykuł.

As an island nation, the topic of training and sending out seafarers is a present challenge in Japan. Awareness activities for elementary, junior high, and senior high school students are essential for securing future mariner job candidates. In this study, we conducted maritime and marine educational methods using various procedures to raise awareness about previous maritime industries. We also brought in maritime specialists for junior high school students who will be continuing to maritime educational institutions, and conducted a comparative study of the results. In this study, we compared three types of educational content: lectures on leadership techniques, observational field trips, and hands-on lessons. The results showed that students had the highest interest in the hands-on lessons, followed by observational field trips, then finally the lectures. These results demonstrated that when creating class content for maritime and marine education, this should be adapted to the identity of the young people who are to receive that education.

Purpose: The aim of this study was to examine the sitting position (posture) of wheelchair basketball (WB) players who cannot walk and can walk in daily life and to compare them with the able-bodied sedentary individuals. Methods: A total of 22 male individuals, including six WB players who could not walk in daily life, eight WB players who walked in daily life, and eight able-bodied sedentary individuals (control group) were included in the study. Posture analysis of individuals was evaluated using rastersterographic system DIERS formetric 4D device. Kruskal–Wallis test was used to compare the data obtained during posture analysis. The Mann–Whitney U-test was used to determine which group caused the difference in the data determined to be different. Statistical significance level was taken as P < 0.05. Results: Trunk-length, sacrum-width, sagittal and coronal imbalance, trunk-torsion, pelvic-obliqueness, pelvic-torsion, pelvic-inclination and fleche-cervicale were found to be values similar in the three groups (P > 0.05). It was determined that the lumbar lordosis and thoracic kyphosis angles were different between the groups, and the lumbar lordosis and thoracic kyphosis angles of the WB players who could not walk in daily life were higher than those of the WB players who walked in daily life and the control group (P < 0.05). Conclusions: Based on the results of our study, we suggest evaluating the sitting postures of WB players and rehabilitating WB players, especially those who cannot walk in daily life, with posture corrective exercises aimed at reducing and normalizing thoracic kyphosis.

Vertical jump tests are used to assess lower-limb power of athletes in sport sciences. Flight time measurement with jump-mat systems is the most common procedure for this purpose. The aim of this study was to analyze the concurrent validity and reliability of two proprietary systems (Globus and Axon) and an open-source system (Chronojump). Methods: A conditioning electric circuit governed by a controlled wave generator is designed to substitute athletes jumping on a physical mat. In order to look for possible differences associated to timekeeping by each microcontroller device, all three systems are fed by the circuit simultaneously. Results: Concurrent validity was high for the three systems. Standarized typical error of estimate (TEE) was trivial, according to MBI interpretation, as well as perfect Pearson correlation coefficient. Reliability was assessed using coefficient of variation of flight time measure, resulting in 0.17–0.63% (0.05–0.12 cm) for Globus, 0.01% (0.09 cm) for Chronojump and 5.65–9.38% (2.15–3.53 cm) for Axon. These results show that all jump-mat system produced nearly identical measures of flight time so they can be considered valid and reliable for practical purposes. In comparison, Chronojump showed the best performance whereas Axon showed enough variability and disagreement to pose a problem in testing elite athletes. Conclusions: These experiments show that open-source jump mats are as valid and reliable as their proprietary counterparts at a lower cost. Therefore, practitioners can be confident in using Globus or Chronojump systems to test athletes’ jump height because of their negligible errors and Axon system to monitor general population.

Przedstawiono problematykę zaopatrzenia w wodę Ośrodków Sportu i Rekreacji (OSiR) w tym stosowane technologie oczyszczania wody basenowej na podstawie analizy systemów oczyszczania wody w wybranych obiektach. Na przykładzie trzech OSiR przedstawiono obowiązujące przepisy prawne, rozwiązania przygotowania i rozprowadzania wody na basenach, ocenę przydatności i efektywności przyjętych obiegów wody i systemów jej oczyszczania. Stwierdzono, że zasadne jest stosowanie układów technologicznych opartych na koagulacji powierzchniowej wody, ozonowania, filtracji przez złoża węglowe i dezynfekcji promieniami UV czy podchlorynem sodu.

This paper presents results of the study devoted to analysis of impact of upper extremities' momentum on the jump length and analysis of selected kinematic data changes during the standing long jump. Four young sportsmen participated in the initial study. They have performed standing long jump in two measuring conditions: with and without arms swinging. Motion was captured using a 3D opto-electronic camera system SMART (BTS) and selected kinematic data were evaluated using software packages and data processing: trajectory of body centre of gravity (COG), velocity of COG, maximal vertical distance of COG, take-off angle together with momentum of upper extremities were analyzed. The data were statistically evaluated using descriptive statistics and analysis of variance. Statistical significance of the kinematic data and jump length were analyzed using the Kruskal-Wallis test and post-hoc test (p<0.05) in Statistics toolbox of Matlab program. Statistically significant differences were assessed within intraindividual and intraclass comparison of data.
