Opis:
The aim of this study was to find out whether Masters class swimming affects strength disproportion and if there is a correlation between the length of sport swimming training in Masters swimmer’s past (SST) and strength parameter’s deficits? Eighteen Masters category swimmers affiliated in Szczecin Masters Team (178.3 ±2.28 m; 77.9 ±2.86 kg) participated in the study. Isokinetic strength measurement was made on Biodex S4 dynamometer. Subjects performed shoulder flexion/extension moves: 3 repetitions – 60 deg/sec and 20 repetitions – 180 deg/sec. Following values were used: peak torque (PT), maximal repetition work (MRW), coefficient of variation (COV), total work (TW), average power (AP), agonist to antagonist ratio (AG:AN). None of the investigated variables were statistically significant in side to side comparison. All of the parameters were higher in extension. Also, no statistically significant difference between sides in AG:AN. Moderate positive correlation was found between SST and PT deficit in extension movement (0.420). Also low positive correlation between SST and PT deficit in flexion (0.396), and MRW deficit in extension (0.352). Masters class swimming did not affect side strength disproportion or agonist to antagonist differences. However, it is possible that swimming training in other categories does.

Opis:
The purpose of this paper was to confront some selected physiological parameters that describe aerobic capacity with young swimmers’ sports achievements. For the study, some athletes with the average age of 14.67, who train swimming at the SMS Szczecin Club, were selected. A progressive test of their oxygen power was performed in order to determine their aerobic capacity, with the means of the European Ranking (LEN). Each swimmer’s sports level was presented in points [pts.]. The swimmers’ characteristics were presented as divided into three groups: (S) – short-distance specialization, (M) – medium-distance specialization and (L) – long-distance specialization. In group (S), maximum oxygen consumption – VO2max [l/min] achieved the levels of 3.95 [l/min] (male swimmers) and 2,77 [l/min] (female swimmers); in group (M) – 4.12 [l/min] and 2.97 [l/min], respectively; and in group (L) – 4.14 [l/min] and 3.338 [l/min]. Among male swimmers, level of VO2 max [ml/kg/min] equaled 58.96 – group (S), 59.72 – group (M) and 62.10 – group (L); while among female swimmers it reached 48.67 (S), 49.36 (M) and 54.60 (L), respectively. The recorded values of VO2 max [ml/kg/min] qualify the young swimmers to the group of people with a very high physical capacity. Our selection of Szczecin’s athletes to individual groups proved to be correct. The considerations presented in the paper bring one’s attention to the substantive quality of the intake and selection of swimmers. In the selection, it is necessary to take such physiologic rates as VO2 max or VO2/HR into consideration.

Opis:
The purpose of the present study is to assess the physique and fitness status of young school and college age swimmers from West Bengal. This cross sectional study was carried out on 46 male and 9 female swimmers of 9-20 years of age. The study parameters include body height, body weight, BMI, different anthropometric parameters, skinfold thickness and aerobic power, strength, flexibility, blood pressure and pulmonary function. Besides, history of training was taken by questionnaire. In the present study male and female adolescent swimmers have significantly higher body fat than their non-swimmer counterparts. Besides, respiratory capacity, max. oxygen consumption and flexibility parameters are significantly higher in male and female swimmers than in control group boys and girls. Besides, highly significant correlation has been found between sitting height, arm span and hand span of swimmer with swimming speed, years of training(swimming) and percentage of body fat. Again, pulmonary function, strength and max. oxygen consumption parameters are significantly correlated with years of training and speed of training. Therefore, simple regression equations are constructed to predict strength, respiratory and cardio-vascular parameters of adolescent swimmers on the basis of years of swimming and speed of swimming. When different style of swimming is considered it has been observed that highest Vo2 max value has been found in free style and butterfly swimmers followed by breast stroke and then back stroke swimmers. Swimmers of the present study when compared to international standard, they are shorter and lower in body fat content values and some physiological parameters like Vo2 max, flexibility and hand grip strength than international standard values. From this study it can be concluded that as there is no available information regarding strength, cardiovascular and respiratory status of adolescent girls and boys swimmers of West Bengal, this study can be said to be a pilot study on the basis of which further elaborate investigation requires to be initiated. Thus these baseline information of physique and physiological parameters of adolescent swimmers will provide local database for coaches and sports physiologists to develop proper training schedule and for identification of talent in the early ages.

Opis:
Critical moments during gymnastic exercises are those related to landing and suppressing overloads, transmitted through lower limbs. A swimmer’s lower limbs provide a good body position in the water and maintain the balance. Both in sports authors postulate reaching bilateral, steady development of the athlete’s body. The main aim was identification and a comparative analysis of the hip, knee and ankle joints flexors and extensors strength, of highly qualified gymnasts and swimmers. Ten healthy subjects participated in the investigation. Five gymnasts (22.2 ±7.3 y.o., 169.4 ±3.91 cm, 64.4 ±3.78 kg) and five swimmers (20.5 ±1.3 y.o., 186.2 ±1.64 cm, 78.4 ±2.61 kg) were highly qualified Polish athletes. Strength measurements were made on Biodex S4 isokinetic dynamometer. Subjects performed hip extension/flexion in lying position, knee extension/flexion and ankle plantar/dorsi flexion. Strength parameters of the lower limbs differentiate gymnasts and swimmers. Lower limb’s strength parameters can be used during training, control, selection or prevention. To achieve a high sport level, swimmers must demonstrate higher strength parameters of lower limbs than gymnasts. The value of work in the maximum repetition (MRW) should be thoroughly analyzed. Highly qualified gymnasts and swimmers should take into account the harmonious, bilateral strength development of the lower limbs.

Opis:
Specific characteristics of sport disciplines require their performers to meet certain demands, also those related to body build. A success is conditioned, among other things, by the morphological structure of competitors. For this cause, their somatic features should be taken into consideration in the selection process. The aim of this research was to describe the level of morphological development and body proportions of swimmers in comparison to their non-practicing peers. What is more, different methods were used to evaluate body tissue composition. The research was based on the measurements of 33 swimmers and 36 non-practicing sport males as a control group, with the average training period of 9 years. The subjects ranged from 18 to 23 years of age. The anthropometric features were examined. Two methods, anthropometric and bioelectrical impedance, were used to estimate the amount of body fat. Athletes performing swimming are characterized by the significant body height, long trunk, wide range of arms and highly developed shoulder girdle. Directed and systematic training has an influence on a great development of the upper part of the trunk and a slight decrease in body fat. The observed differences indicate that depth, circumference and mobility of the chest developed in swimming have a positive influence on the respiratory system. Poor differences observed in the amount of fat in the athletes and non-practicing subjects may result from the fact that the body accumulates fat tissue, used as a good thermal insulation.

Introduction: Purpose of swimming lessons is to teach non swimmers how to swimm and remove their fear from water, with swimmers we are improvin g individual swimming st yles. The aim of the study is to monitor the level of the swimming abilities at FCHPT and compare it with the swimming standards. Methods. The experimental sample consisted of 1160 respondents (494 boys and 666 girls) from the Faculty of Chemical and Food Technology, Slovak Univerzity of Technology in Bratislava. . Measurement was carried out in the 25 meter indoorpools in Bratislava. We have tested the swimming ability by 100 meters free style. This kind of test is normally used in educational practice. The choice of swimming style is not critical in terms of the achieved time as in competitive swimming, because many times students have achieved better times when they were swimming breaststroke than free style with many technical mistakes. Men and women of co mpetence we compared with standards from the year 2000. The results : Based on our results, we found that the number of non - swimmers decreased compare to the year 1985. Since 1995 it is basically at the same level. In 1995 it was around 27%, in recent years , the number of non - swimmers have already dropped to a level of around 10%. In 1985 females non swimmers were almost 38%, in the following years the value stabilized between 15 - 20%. When comparing the changes in the level of competence in a range of 30 yea rs we basically have not found out any abnormalities besides years 1995 - 1996. In all years the average measured time has been almost at the same level. Comparing to standards, men on level 136.7 s, women on level 172,4, (Macejková, 2008), our students swam around these levels. Only years 1995 - 1996 differs significantly because our students swam better than listed standards.. Summary: Since 1979, it is the duty of the school to provide a swimming course for its students. We assume that the main cause of the high number of non - swimmers in 1985 was that university students did not have the opportunity to learn how to swim when they were younger. In 1995 on the other hand started to study at the university students who had already completed this training and it is reflected in the number of non - swimmers. Nowadays, these swimming courses depend on the financial situation of schools and parents, because they support it. As these days swimming is not a mandatory course at primary and secondary schools, we are try ing to remove illiteracy by including swimming as a compulsory subject in the first year at our faculty.

We study the exact and approximate controllabilities of the Langevin equation describing the Brownian motion of particles with a white noise. The Langevin equation is shown to describe also the bacterial run-and-tumble motion. Applying the Green’s function approach to the Green’s function representation of the Langevin equation, we obtain necessary and sufficient conditions for exact controllability in the form of a finite-dimensional problem of moments. For the approximate controllability, we obtain only sufficient conditions. The sets of resolving controls are characterized in both cases. The theoretical derivations are supported by a numerical analysis.

Opis:
Adolescence is a period between age 10 and 19. Intensive changes associated with the development of the organism influence the nutritional needs during this period. Young swimmers’ training is characterized by large volume, so their diet can play an important role in their results and future career. The energy intake of a developing athlete should be determined individually based on gender, anthropometric measurement, character, and number of workouts per day. The frequent presence of drowsiness and fatigue during training may indicate insufficient dietary energy supply. Dehydration exceeding 2% of body weight should be prevented. Isotonic drinks should only be consumed during training longer than 75 minutes. Young swimmers should consume adequate amounts of carbohydrates to restore glycogen reserves before another training unit. Carbohydrates with a high glycemic index of 1-1.2 g/kg b.w./h should be delivered during the post-training period. Immediately following training, a meal containing a complete protein should be consumed to accelerate post-exercise recovery. The total protein supply should be at least 1.2 g/kg b.w./h. The minimum intake of fat in the diet of a young swimmer should be 2 g/kg lean b.w. It is recommended to limit products containing large amounts of saturated fatty acids.

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).

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.

The aim of the study was to follow-up the stability of young talented swimmers’ performance and its biomechanical determinant factors (i.e., anthropometrics, kinematics, hydrodynamics and efficiency) during a competitive season. Thirty three (15 boys and 18 girls) young swimmers (overall: 11.81 ± 0.75 years old and Tanner stages 1–2 by self-evaluation) were evaluated. Performance, anthropometrics, hydrodynamics, kinematics and efficiency variables were assessed at three moments during a competitive season. Performance had a significant improvement (with minimum effect size) and a moderate-very high stability throughout the season. In the anthropometrics domain all variables increased significantly (ranging from without to minimum effect size) between moments and had a moderate-very high stability. Hydrodynamics presented no variations between all moments and had a low-very high stability throughout the season. In the kinematics domain, there were no variations between moment one and three, except for an increase in stroke frequency (without size effect). Speed fluctuation remained constant, with no significant variations. All kinematic variables had a low-very high stability. Efficiency variables did not present variations between moment one and three and had a low-moderate stability. Overall, young swimmers showed a minimum improvement in performance and in anthropometric factors; and a moderate stability of performance and its determinant factors (i.e., anthropometrics, hydrodynamics, kinematics and efficiency) during the competitive season.

Aim of the current study was to examine the reliability and validity of a new tool, developed for the assessment of young swimmers’ technique in all swimming strokes. The sample of the study was 119 swimmers (63 boys and 56 girls), aged 8 to 12 years old. To evaluate swimmers’ technique, each of them performed 15m for each one of the swimming strokes in individual medley order. Α digital camera, placed 5m above the pool’s surface, recorded the swimming bouts. Three experienced swimming coaches evaluated the recorded videos with the new technique’s evaluation tool named Tec Pa. Tec Pa assess six important key points of swimming technique in each stroke. According to the results no statistical significant differences were showed between the scores of the swimmers’ evaluation by the three coaches (p > 0.05). Moreover, the association between the scores was statistically significant high (τ = 0.863; p < 0.05). The findings of the current study reveal that Tec Pa is valid and reliable for the young swimmers’ technique evaluation, with high strength of association. Also, Tec Pa can be used by the coaches to enhance the free observation method, which is mainly used, in young swimmers.

Objective: The aim of this study was to determine the effect of regular winter swimming on the morphological parameters of blood and the distribution of body surface temperature among winter swimmers.Methods: The study involved 10 winter swimmers from the “Kaloryfer” Krakow Club of Winter Swimmers. During winter, from November through April, they regularly (once per week) immerse themselves in cold water. Venous blood samples were collected twice: at the beginning of the season and after the season. Thermal images were taken three minutes before immersion in cold water and immediately after it.Results: Swimming in cold water induced a significant increase in red blood cells and haematocrit and a significant decrease in mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration. No changes were found in white blood cells, platelets, haemoglobin or mean corpuscular volume. Body surface temperature decreased due to immersion in cold water. Conclusions: Regular winter swimming results in considerable, non-pathological changes in haematological parameters and body surfacetemperature among winter swimmers.
Cel pracy: Celem pracy było ukazanie wpływu zimowych kąpieli na parametry morfotyczne krwi oraz rozkład temperatury powierzchniowej ciała. Materiał i metody: Badania zostały przeprowadzone na grupie członków Krakowskiego Klubu Morsów „Kaloryfer”. Podczas sezonu trwającego od listopada do kwietnia zanurzali się oni regularnie (raz na tydzień) w wodzie o niskiej temperaturze. Od badanych osób pobrano dwukrotnie krew żylną, na początku sezonu oraz po jego zakończeniu. Wykonano zdjęcia termowizyjne przed zanurzeniem na 3 minuty w wodzie oraz po wyjściu z wody. Wyniki: Zaobserwowano istotne statystycznie zwiększenie się liczby czerwonych krwinek oraz hematokrytu oraz istotne statystycznie obniżenie się średniej masy hemoglobiny w krwince czerwonej oraz średniego stężenia hemoglobiny w krwince czerwonej. Nie stwierdzono istotnych statystycznie zmian w liczbie białych krwinek, liczbie płytek krwi, stężeniu hemoglobiny oraz średniej objętości krwinki czerwonej. Pod wpływem zanurzania się w wodzie o niskiej temperaturze nastąpiło obniżenie się temperatury powierzchniowej ciała u włączonych do badania osób. Wnioski: Regularne pływanie w zimnej wodzie wywołuje silne niepatologiczne zmiany we właściwościach hematologicznych krwi.

Opis:
The research goal was to analyse training loads during specific preparation period among swimmers with disabilities. Double examination of 20 athletes with disabilities of motion and sight organs, at the beginning and at the end of the period was conducted. Garmin Forerunner 735XT device was used as a measuring tool, which registered heartbeat rate during training sessions. Records of the heartbeat rate were sent up to Garmin Connect programme, where percentage share of each energy zone in the whole training volume was calculated. Taking into consideration the achieved results, during specific preparation period, swimmers were training mostly with moderate and high intensity and the biggest training volume was registered in zones EN2, EN3 and SP1. Additionally, between the first and the second measurement, the biggest decrease in training volume took place in EN, whereas the biggest increase in training volume took place in zone SP1 what indicates increase of work in the field of specific endurance.

Opis:
Controlling swimming speed is an important factor as far as accomplishing swimming training tasks is concerned. The aim of this study was to determine the importance of visual information about control of swimming speed in threshold training for swimmers. Six swimmers took part in this experiment. The study consisted of two exercise tests in which the participants swam 10 x 100m. Individually designated task time corresponded to intensity of 95-100% of anaerobic threshold (AnT) intensity. AnT was determined in a progressive test prior to the experiment. In the first exercise test participants did not receive information regarding their swimming speed. In the second test visual information regarding their swimming speed was transmitted in real time using the Swimming Pace Control System device. The effect of visual control of swimming speed in threshold training for swimmers was determined by measuring the time needed to complete the test distances, heart rate and lactate concentration. Visual information used in swimming speed control in real-time statistically significantly reduces the differences between the assumed and actual time needed to complete the test distance (p=0.057). Visual control of swimming speed resulted in an appropriate level achievement of intensity for threshold training, which was measured by swimming time (inaccuracy 6.97±1.38 s), heart rate ( 162.7±15.9 beat/min), and lactate concentration ( 4.70±1.78mmol/l). Comparing the increase in lactate concentration and exercise test with visual information, statistically significant differences are not observed (p=0.710; p=0.947). However, among 33.33% of the subjects, lactate concentration after training without visual information did not meet the standards (4 to 5 mmol/l) of threshold training (8.85 mmol/l and 14.57 mmol/l). Additionally, value of standard deviations of lactate concentration after threshold training with visual information amounted to 37.87% mean of lactate concentration, and in the condition without information 84.00% mean of lactate concentration. The results indicate the need to use concurrent visual information provided in real-time allowing you to control the swimming speed in swimming training.

Opis:
The aim of this article is to make the assessment of physiotherapy use in the case of swimmers’ regeneration. A diagnostic survey was used as the method. Opinions from the author’s survey were considered and there were 30 high-class swimmers analyzed aged 15–27. The research was conducted in 2012 at the Floating Arena swimming pool in Szczecin. 100% of the surveyed swimmers benefit from regeneration after physical effort. The most common physiotherapist treatment in case of swimmers is dry classic massage – 86.7%. The water bath (63.3%), sauna bath (56.7%), whirl bath (53.3%), water jets/Scotch douche (43.3%) and hydro massages (30%) are the most common types of hydrotherapy. On the other hand, ultrasounds and cryotherapy are the least common treatments when choosing adequate types of regeneration, i.e. respectively 13.3% and 3.3%. The biggest amount of massages is performed shortly before start – 40%. Massage in 60% cases lasts 10 minutes. In 90% of the surveyed group partial massage is being applied, whereas only 3.3% of competitors take the overall massage. In case of 80% of the swimmers, massage is regarded as completely relaxing. For 77% of them it relaxes both physically and mentally. In case of 80% of the surveyed, it is regarded as the most efficient form of biological regeneration. 60% of swimmers say it is helpful to maintain readiness to start and to overcome fever (feeling of annoyance) or apathy.

Opis:
The dynamics of performance in professional sport requires a systematic improvement of the training process. Such activities should also include optimizing the children and youth training in these disciplines, where an early specialization operates. The main aim of this paper was to search for the relationship between swimmer’s segmental kinematics (segmental velocities, stroke rate, stroke length, stroke index); the relationship between swimmer’s technical skill level (in four competitive swimming techniques) and training overloads taking into consideration gender and age effect. The study group consisted of 121 swimmers (69 female and 52 male), of the Polish 12–15 age group swim team, volunteered to serve as subjects. Video-based methods and video equipment are being applied to assist qualitative and simple quantitative analysis for immediate feedback and research in swimming. Both technical skill level preparation and segmental kinematics of 12–15 year old swimmers proved to be highly conditioned by implemented training intensity ( p < 0.001), as well as the volume of training (high and average trade at a level of significance p < 0.001). Implemented training overloads expressed by both volume and intensity of training showed high and very high correlation with the swimming efficiency, presented segmental kinematics and technical skill level, however, there appeared particularly pronounced relationship with the size of kinematic parameters taken into account in four competitive swimming techniques, components of the 100 m individual medley.

Opis:
Przebywanie w środowisku wodnym (nurkowanie, pływanie) zwiększa ryzyko zapadalności na choroby górnego odcinka układu oddechowego. Celem pracy była próba porównania częstości zachorowań na choroby górnego odcinka układu oddechowego w grupie nurków z grupami osób w tym samym wieku, uprawiającymi pływanie wyczynowo lub sporadycznie. Uzyskane wyniki badań potwierdziły większą częstość występowania infekcji górnych dróg oddechowych w grupie nurków i grupie osób uprawiających pływanie wyczynowo w stosunku do grupy osób uprawiających pływanie sporadycznie. Różnice statystycznie istotne dotyczyły stanów zapalnych błony śluzowej gardła i upośledzenia powietrzności zatok. Nie stwierdzono różnic statystycznie istotnych w częstości występowania tych chorób między nurkami i pływakami wyczynowymi z wyjątkiem urazu ciśnieniowego zatok.
Water sports such as diving and swimming increase the risk of upper respiratory tract illnesses. The aim of this paper is to compare the frequency of the upper respiratory tract morbidity in a group of divers with groups of persons of the same age that swim professionally or sporadically. The results obtained confirmed that infections of upper respiratory tract occur more frequently in the group of divers and professional swimmers than in the group of sporadic swimmers. The statistically significant differences concerned pharyngitis and impaired sinus aeration. There were no statistically significant differences concerning the incidence of those illnesses among divers and professional swimmers, except for sinus barotrauma.

Opis:
The aim of the work was to assess the training loads of disabled swimmers in the comprehensive preparation subperiod. The research was carried out on 12 swimmers of the WZSN “START” Wrocław swimming club section. All swimmers started in the “S” start group. The average age of swimmers was 24 years and the average training time was 8 years. The pulse rates were analyzed 6 times during the training, just before the training, in the 10th minute of the warm-up, in the 45th minute at the peak of the training, in the 80th minute, in the 90th minute immediately after the training, and in the 105th minute after the rest. A Polar 810i Sport-tester was used to evaluate the heart rate. Statistical analysis was used. For all the swimmers the average heart rate values after 15 minutes of rest did not return to resting heart rate values. In addition, the swimmer’s fatigue was assessed using the Borg scale. The training load was moderate, and on the Borg scale, the swimmers assessed their fatigue as very heavy.

Opis:
Competitive swimmers have a high incidence of breaststroke-related knee injuries. The cause of the breaststroke swimmer’s knee, which is accompanied with medial pain of the knee joint, has not been clearly identified. The purpose of this investigation was to determine the biomechanical and anatomical factors which predispose subjects to injury. This study includes 60 breaststroke and crawl swimmers (16 ±3.2 years old) who have participated in 3–6-year-long swimming training in Tabriz city. The knee pain was evaluated with McGill’s pain questionnaire, and Q angle was measured with universal goniometry by knee radiography in standing position. The medial pain of knee joint increased significantly and the knee was only symptomatic when the swimmers performed the whip kick. Breaststroke swimmers were hardly able to complete training because of the knee pain. It is concluded that competitive training of breaststroke swimming for 6 months can cause exclusive injury and pain in swimmer’s knee. On the other hand, the result showed that there is a direct relationship between the swimmer’s Q angle amount and chance of the knee injury. This emphasizes a scrious consideration of Q angle states in breaststroke swimmers.

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.
