Opis:
The aim of the work was a omparative analysis of laryngologic diseases in swimmers and people swimming for recreation. The examination was carried out in the period from April 2004 to April 2005 in the group of 64 swimmers aged 10-25 years, and the group of 53 fourth-year students of the University of Physical Education and Sport in Gdańsk. The information was compiled on the basis of a uestionnaire. The results were later estimated by means of comparison between the kinds of laryngologic diseases occurring in both groups. It was shown that the kinds of diseases differ in competition swimmers and people swimming for recreation. It was also found that the competition swimmers more frequently suffer from diseases of the upper airways among which the dominating problems seem to be the infections of the nose, sinuses, ears and throat.
Celem pracy była analiza porównawcza schorzeń laryngologicznych występujących u pływaków i u osób pływających rekreacyjnie. Badanie przeprowadzono od kwietnia 2004 do kwietnia 2005 wśród 64 pływaków w wieku 10-25 lat i 53 studentów IV roku AWFiS w Gdańsku. Informacje zebrano przy pomocy kwestionariusza ankiety. Uzyskane wartości oceniano przez porównanie występujących schorzeń laryngologicznych w badanych grupach. Wykazano występowanie różnic w rodzajach schorzeń wśród zawodników pływania i pływających rekreacyjnie. Stwierdzono, że pływacy częściej zapadają na schorzenia górnych dróg oddechowych wśród których dominują infekcje nosa i zatok oraz uszu i gardła.

Opis:
Swimming as a discipline that requires specific conditions for both training and recreation suffered greatly during the pandemic period. Due to the closure of swimming pools, school swimming pools, and aquaparks, it was impossible to practice this sport. Safety considerations, as an overriding social responsibility objective, and thus reducing disease incidence have been at the forefront of the fight against coronavirus. The paper attempts to explore the safety measures used to curb the spread of COVID-19 and the restrictions on swimming pools that have been put in place after their opening.
Pływanie jako dyscyplina, w której potrzebne są specyficzne warunki zarówno do treningu oraz rekreacji bardzo ucierpiało w czasie okresu pandemii. Przez zamknięcie pływalni, basenów szkolnych czy Aquaparków nie było możliwe uprawianie sportu pływackiego. Względy bezpieczeństwa, jako nadrzędny cel związany z odpowiedzialnością społeczną, a tym samym zmniejszenie ilości zachorowań były i są na pierwszym miejscu w walce z koronawirusem. W niniejszym opracowaniu podjęto próbę eksplanacji środków bezpieczeństwa użytych w celu ograniczenia rozprzestrzeniania się COVID-19 oraz jakie obostrzenia na pływalniach zostały po ich otwarciu wprowadzone.

Opis:
Early identification of anthropological potential in swimmers is considered important to the recruitment and selection of children and adolescents to perform extensive and strenuous training. The aim of the research was a comparative analysis of the anthropometric parameters and indicators of adult, elite swimmers with people who had never trained for swimming. It was assumed that the specific characteristics of the swimmers’ somatic composition referred to the laws of swimming biomechanics. Methods: Anthropometric measurements were taken in a group of elite male swimmers (N = 28), aged 17–24. The same set of measurements was taken in a homogeneous control group of students of physical education. An anthropometric profile significantly differentiating swimmers from the control group was constructed. Next, a linear forward stepwise discriminant analysis was conducted to investigate which indices can be used to distinguish the two groups. Results: It seems significant that a specific somatic composition trait of swimmers in the form of a relatively long shank was observed, which had not been observed in earlier studies. Additionally, indices of relatively slim hand dimension, and indices describing a “reversed triangle” shape of trunk, were the most powerful discrimination variables between the two examined groups. Conclusion: The results obtained cannot be generalised to the entire population of swimmers, however referring them to the laws of biomechanics of swimming allows for the continuation of research into identifying the prognostic traits desirable for success among young swimmers.

Opis:
The aim of this study was to analyse changes taking place within selected kinematic parameters of the swimming start, after completing a six-week plyometric training, assuming that the take-off power training improve its effectiveness. Methods: The experiment included nine male swimmers. In the pre-test swimmers performed three starts focusing on the best performance. Next, a plyometrics training programme, adapted from sprint running was introduced aimed at increasing explosive power of the lower extremities; the programme entailed 75 minute sessions conducted twice a week. Afterwards, a post-test was performed, analogous to the pre-test. Spatio-temporal structure data of the swimming start were gathered from video recordings of the swimmer both above and under water. Results: Impulses triggered by the plyometric training contributed to a shorter start time (the main measure of start effectiveness) and glide time as well as increasing average take-off, flight and glide velocities including take-off, entry and glide instantaneous velocities; the glide angle decreased. Conclusions: The changes in selected parameters of the swimming start and its confirmed diagnostic values, showed the areas to be susceptible to plyometric training and suggested, that applied plyometric training programme aimed at increasing take-off power enhances the effectiveness of the swimming start.

Opis:
The information about the workload on individual muscles in the course of a specific physical activity is essential for targeted prevention, early diagnosis and suitable therapy concerning their overloading and injury. The aim of this study is to evaluate temperature changes in particular skin areas in the course of front crawl swimming, caused by muscle work. Methods: Thermograms were taken of 13 students of Defense University immediately and 15 minutes after swimming 1,000 m focused on 20 regions of the skin over the selected agonists and synergists in upper extremities and body. FLUKE TiR infrared hand camera was used. Results: The results indicated the significant increase in the relative temperatures in the areas of agonists of swimmers’ movement – triceps brachii: from 0.952 to 0.997 of normalized units (nu) on the right and from 0.955 to 0.986 nu on the left. At the same time, the temperature of the muscles participating in lifting the arms above the water surface and stretching them forward – deltoids – increased as well (rear part: from 1.002 to 1.015 nu on the right and from 1.002 to 1.014 nu on the left, sides: from 1.008 to 1.023 nu on the right and from 1.011 to 1.023 nu on the left). Conclusions: In conclusion, the order of the other agonists is as follows: biceps brachii, pectoralis major muscle, and latissimus dorsi. This study provides the options for objective assessment of workload on specific muscles or muscle groups during front crawl swimming.

The purpose of this study was to determine the reliability of shoulder isometric strength assessment using the microfet 2™ dynamometer in adolescent swimmers. Methods: Twenty-nine participants (16.2 ± 1.2 years old; 59.05 ± 6.98 kg of body mass) were tested using the microfet 2™ dynamometer. Swimmers performed an isometric strength test (IST) in two distinct occasions with 7 days apart in order to calculate the reliability. All participants were asked to perform a maximal isometric contraction from the external and internal shoulder rotators in a prone body position. Results: The external and internal shoulder rotators showed an excellent intraclass correlation coefficients for both shoulders, with more than 0.90 and a low percentage of method error variation. The external/internal ratios reliability was good in dominant (ICC 0.80) and non-dominant (ICC 0.81) shoulders. The reliability using Bland–Altman method showed that systematic errors (mean difference between test-retest) were nearly zero and the 95% limits of agreement narrow, indicating a good reliability. Conclusions: It can be concluded that microfet 2™ is a reliable apparatus for measuring the strength of the external and internal rotation of the shoulder in swimmers. Its light weight and easy portable characteristics can help swimming coaches monitoring specific dry-land strength training programs for their swimmers.

Opis:
The purpose of the study was to analyze the relationships between sprint swimming performance, dry-land power, and kinematics in master swimmers. Twenty-two male master swimmers were separated in two groups based on their chronological age: (i) 30–39 years and; (ii) 40–49 years. Maximum dry-land power was determined through counter movement jump and 3 kg medicine ball throwing (Hmax and Tmax, respectively). Kinematic determinants of performance were measured during a maximal bout of 15, 25 and 50 m front crawl (T15, T25, T50). Stroke frequency (SF), stroke length (SL) and stroke index (SI) were calculated as kinematical aspects of the stroke. In the 30-39 group, SI25 was correlated to T25 (r = –0.76, p < 0.01, η2 = 0.96), the same was observed between SI50 and T50 (r = –0.83, p < 0.01, η2 = 0.96). Only SI50 was significantly correlated to T50 (r = –0.86, p < 0.01, η2 = 0.97) in the 40–49 years age cohort. In dryland power variables, Hmax and Tmax were only correlated in the younger master swimmers group (r = –0.87, p < 0.01, η2 = 0.97). There were no significant differences (p < 0.05) between younger (30–39 years) and older (40–49 years) swimmers groups in dry-land tests (Hmax 28.5 ± 5.9 vs. 26.5 ± 3.9 cm and Tmax 4.2 ± 1.0 vs. 4.2 ± 1.1 m). Our results suggest that swimming performance in younger master swimmers (30–39 years) seem more dependent on kinematic swimming variables than on strength parameters, which were most related to swimming performance in the older master swimmers (40–49 years).

Opis:
Maintaining the body underwater in the so-called vertical position, where the body is inverted (head down) and balanced, is made possible by performing the support scull movement by the upper limbs. In synchronized swimming, the main criteria for judging this vertical position are maintaining body stability and the maximum height of the lower limbs one is able to extend out of the water. Therefore, it seems important to examine for any correlations between the symmetry of the upper limb’s movement (sculling) and the ability to maintain balance of the body. The aim of this study was to use a dynamical asymmetry index (DAI) to assess the symmetry of the upper limb movements performed in synchronized swimming. The use of the dynamical asymmetry index is considered to be advantageous over the asymmetry coefficient, which is better known in literature on the subject and has been used by numerous authors, as it not only evaluates the magnitude of the asymmetry, but also indicates in which phases of movement asymmetry is the greatest or where it is the least significant.

Opis:
The study aim was determining gender-related differences of underwater undulatory swimming (UUS) kinematic indicators and their impact on UUS velocity. Methods: The study included 18 girls (F: age 16.71 ± 0.64 years, FINA points 551 ± 68) and 23 boys (M: age 16.79 ± 0.57 years, FINA points 533 ± 66) training swimming. After marking characteristic anatomical points, subjects performed approximately 7 meters of UUS. A filming device placed behind the underwater window registered the trial. Recordings were analysed using the SkillSpector programme. Results: Boys swam faster (F: 1.24 m/s, M: 1.35 m/s), overcame a greater distance during one cycle (F: 0.67 m, M: 0.74 m), performed movements with higher toes amplitude (F: 0.58 m, M: 0.63 m), obtained higher amplitude and frequency product (F: 1.05, M: 1.15) and smaller ankle joint range of motion (F: 64°, M: 57°). In both groups, relationships between velocity and: maximal ankle joint extension, distance covered during one cycle and backward toes shift during downward movement were found. The results were statistically significant ( p < 0.05). Conclusions: Girls and boys differed in kinematic indicator level, but UUS velocity depends on identical kinematic variables, meaning UUS technical training can be performed without gender-division.

Opis:
Background and aim: This article concerns a topic in the field of sport psychology. Its purpose was to create a young athlete personality model and to identify differences regarding this model among individual and team sport athletes. Material and methods: The young athlete model was developed using the five-factor personality inventory (NEO-FFI). The test sample consisted of boys (N = 60) aged 16-18, who engaged in competitive volleyball (N = 30) and swimming (N = 30). Results: The results of the study led to the conclusion that the young athlete model based on NEO-FFI is characterised by a medium level of neuroticism, extraversion, openness to experience and agreeableness, while the element determining success and, at the same time, distinguishing training from non-training persons is the degree of conscientiousness. Conclusions: In addition, individual sport athletes do not differ in their personality profile from team sport athletes. The final conclusion drawn is that the personality of an athlete is shaped by sport in the broad sense and not by particular sport disciplines.
Zasadność i cel: Artykuł dotyczy tematu z zakresu psychologii sportu. Jego celem było stworzenie modelu osobowości młodego sportowca i określenie różnic dotyczących tego modelu wśród sportowców indywidualnych i drużynowych. Materiał i metody: Model młodego sportowca został opracowany przy użyciu pięcioczynnikowego inwentarza osobowości (NEO-FFI). Badana próba składała się z chłopców (N = 60) w wieku 16-18 lat, którzy trenują wyczynowo siatkówkę (N = 30) i pływanie (N = 30). Wyniki: Wyniki badania doprowadziły do wniosku, że młody sportowiec opisany według metody NEO-FFI charakteryzuje się średnim poziomem neurotyczności, ekstrawersji, otwartości na doświadczenie i ugodowości, a jednocześnie elementem determinującym sukces i odróżniającym trenujących od osób nietrenujących jest stopnień sumienności. Wnioski: Ponadto sportowcy indywidualni nie różnią się pod względem profilu osobowości od sportowców drużynowych. Ostateczny wniosek jest taki, że osobowość sportowca kształtowana jest przez sport w szerokim znaczeniu, a nie przez poszczególne dyscypliny sportowe.

Opis:
The aim of this study is to evaluate the influence of the swimming speed during diving on the biomechanical parameters describing the movement of selected measurement points of the lower limb in professional divers. Methods: The study involved a group of 4 professional divers whose movement was recorded during underwater swimming at slow (approx. 0.4 m · s–1), medium (approx. 0.5 m · s–1), and fast (approx. 0.8 m · s–1) pace. Results: During swimming at medium speed, the divers made a smaller displacement (along the axes Y) of the midpoint of fin than during swimming at fast speed. The range of motion in the ankle joint increased in fast speed in comparison with low and medium swimming speed. The same relationship was noted for the obtained velocity and angular acceleration in the hip, knee and ankle joints. The authors observed that during swimming at slow pace the divers choose movement ensuring high swimming comfort while the efficiency of motion is a secondary factor. On the other hand, during swimming at higher pace, the applied movement pattern ensures far greater efficiency rather than swimming comfort. Conclusion: The conducted analysis showed that divers adjust the movement of their lower limbs to the swimming pace.

Opis:
The aim of the present study was to evaluate the biomechanical (stroke rate, stroke length, and stroke index), anthropometrical (body height, body mass, body mass index, arm span, shoulders width, thigh, leg and upper arm lengths), and muscle architectural (muscle thickness, pennation angle, and fascicle length) parameters as predictors of 200-m front crawl swimming performance in young male swimmers. Twenty-two county level male swimmers (mean ±SD: age: 14.52 ± 0.77 years; body height: 173 ± 5 m; body mass: 60.5 ± 5.7 kg) performed a 200-m front crawl swimming test in a 25-m pool. Stepwise regression analysis revealed that biomechanical parameters (87%) characterized best 200-m front crawl swimming performance, followed by anthropometrical (82%) and muscle architectural (72%) parameters. Also, stroke length (R2 = 0.623), body height (R2 = 0.541), fascicle length of Triceps Brachii (R2 = 0.392) were the best single predictors that together explained 92% of the variability of the 200-m front crawl swimming performance in these swimmers. As a conclusion, with respect to higher performance prediction power of biomechanical parameters, technique should represent the core of the training program at these ages. In addition, these findings could be used for male young swimmers selection and talent identification.

Purpose: The main purpose of this study to analyze the coordination, propulsion and non-propulsion phases in the 100 meters breaststroke race. Methods: Twenty-seven male swimmers (15.7±1.98 years old) with the total body length (TBL) of 247.0±10.60 [cm] performed an all-out 100m breaststroke bout. The bouts were recorded with an underwater camera installed on a portable trolley. The swimming kinematic parameters, stroke rate (SR) and stroke length (SL), as well as the coordination indices based on propulsive or non-propulsive movement phases of the arms and legs were distinguished. Results: Swimming speed (V 100surface breast ) was associated with SL (R=0.41, p<0.05) and with TBL tending towards statistical significance (R=0.36, p<0.07), all relationships between the selected variables in the study were measured using partial correlations with controlled age. SL interplayed negatively with the limbs propulsive phase Overlap indicator (R=-0.46, p<0.05), but has no significant relationship to the non-propulsion Glide indicator. Conclusions: The propulsion in-sweep (AP3) phase of arms and their non-propulsion partial air recovery (ARair) phase interplayed with V 100surface breast (R=0.51, p<0.05 and 0.48 p<0.05) respectively, displaying the importance of proper execution of this phase (AP3) and in reducing the resistance recovery phases in consecutive ones.

Opis:
The main purpose of this study was to analyze tactical solutions used by swimmers, the finalists of the 19th Beijing Olympics in 2008, in individual front crawl events at distances of 50, 100 and 200 m. Observations were carried out on 7 swimmers, the Beijing Olympics medalists competing in front crawl individual events. Detailed analyses were run on: 1) Sports results obtained by the finalists at distances of 50, 100 and 200 m front crawl; 2) block time; 3) results of each 50 m lap time (100 and 200) called split times except 50 m front crawl (there is no split time in 50 m); and 4) the mean swimming speed (V) on individual laps of the analyzed races. To determine the correlation between the response time, the time of individual laps, and the final time of the analyzed front crawl races, Pearson’s linear correlation coefficient r was obtained. As a result of detailed analyses of the test material it is believed that not only tactics for an individual race is important, but equally significant is to elaborate the strategy for the whole event and to prepare the swimmer to compete in the system of heats, semifinals and finals. However, some of the following tactical objectives can be formulated: sprinters (a distance of 50 and 100 m front crawl) should start at maximum speed, according to their abilities, and try to maintain that speed until the end of the race; middle-distance swimmers (200 m front crawl) should adopt the most optimal tactical solutions characterized by increasing speed in the second half of the distance.
