Item Enhancement of post-activation performance enhancement by blood flow restriction following specific on-ice exercise program in ice hockey players(2025) Gabryś, Tomasz; Chruscinski, Radoslaw; Szmatlan-Gabrys, Urszula; Garnys, Michal; Bichowska-Paweska, Marta; Čepička, LadislavIntroduction: Due to the requirements for research on motor skills in elite hockey players, an attempt was made to assess the skills following the application of PAPE and BFR-enhanced PAPE to enhance lower limb power. Methods: An on-ice exercise program was used to determine PAPE factors that included three sets of 3 repetitions of specific on-ice effort, 15 s of work, 15 s of rest, separated by 90 s of free skating. The evaluation of the effectiveness of the PAPE program was measured at the 3rd, 6th, 9th, 12th, and 15th minutes after its application. The flight time during the CMJ and SJ jump was recorded with the OptoJump system, and the jump height (JH) and peak power (PP) were determined. The study involved 20 professional male hockey players aged 17 ± 1 years with 11 ± 2 years of training experience. Results: No differences between JH and PP values in CMJ and SJ before and after PAPE and PAPE with BFR intervention were statistically significant. The BFR application during specific effort showed a statistically significant p ≤ 0.001 increase in work time. Discussion: Significant individual differences in the magnitude of the PAPE and BFR effect between the subjects were also ound. The individualization of exercise stimuli should consider the individual athlete’s profile in terms of susceptibility to the PAPE and BFR program, considering the amount of fatigue it may cause.
Item Effects of physical activity on symptoms of irritable bowel syndrome(2025) Poniewierka, Elzbieta; Szura, Ewa; Valach, PetrIntroduction: Rapid urbanization and constant technological progress contribute to a change in lifestyle in terms of physical activity. Lack of free time and reluctance to engage in physical activity may lead to impaired functioning of internal organs, including the digestive system. Aim: In the present study, by creating an exercise regimen, an attempt was made to demonstrate the impact of this activity on the symptoms of patients with irritable bowel syndrome (IBS). Material and methods: Forty-one women with diagnosed irritable bowel syndrome were included in the study. To assess the effectiveness of the method used, the validated IBS-SSS questionnaire was used. The study used an original training programme based on fitness lessons, yoga positions improving intestinal motility and relaxation techniques: autogenic training developed by Schultz and progressive muscle relaxation developed by Jacobson. Twenty-nine women completed the entire 2-month training cycle, in line with the assumptions of the study. The following methods were used: t-test for dependent samples, Wilcoxon pairwise order test, McNemar's c2 test and Spearman's R correlation coefficient. Results: It was found that nearly 80% of the study participants experienced abdominal pain before participating in the study. The training cycle caused pain in 52% of the surveyed women. The intensity of pain in the subjects decreased by 20%. After the study, the incidence of flatulence decreased by 38% and the severity of flatulence by 30%. Conclusions: The relationship between physical activity and the severity of symptoms of irritable bowel syndrome in the surveyed women was confirmed. The study group of women showed a reduction in IBS-related symptoms after 8 weeks of training.Item The Influence of Substitution Decisions Made by National Team Coaches on Final Match Outcomes at UEFA EURO 2024(2025) Gabryś, Tomasz; Chruscinski, Radoslaw; Garnys, Michal; Sůva, Matěj; Švátora, KarelCoaches leading national football teams during championship tournaments make decisions about tactical substitutions of players in critical match phases. This may be an attempt to change or defend a favorable score. The research focused on the time of decision-making of forced and planned substitutions, considering its characteristics: neutral, offensive, and defensive. The point of analysis of the substitutions was the match outcomes at the time of the substitutions and the final result and impact of the substitution concerning the result. Methods: 51 matches played during the UEFA EURO 2024 football tournament were analyzed during which 466 player substitutions were made. For the statistical analysis of the degree and strength of the relationship between the variables, the Chi-Square Test, Cramer's V coefficient, and Machine Learning were used accordingly. Results: 72% of coaches' decisions to player substitutions resulted from the decision to change the team's tactics by changing the team's setup or the players' positions. The most common negative (69%) or positive (61%) impact occurred from the substitution of a player after the 20th minute. Discussion: The decision trees used in the analysis determined the most advantageous time periods for coaches to make decisions about substitutions. The highest substitution effectiveness rate is obtained when the substitution is made between 60 and 85 minute and the lowest is made between 45 and 60.Item Jak jsou na tom naše děti s pohybem?(2025) Švátora, KarelDěti a pohyb – to je téma probírané stále častěji, a to nejen v souvislosti s tím, jaký vliv má dostatek pohybu na fyzické zdraví, ale intenzivně se diskutuje i vazba fyzických aktivit na psychickou pohodu, a dokonce i na vývoj mozku. Těmto tématům se věnují vědci z Fakulty tělesné výchovy a sportu Univerzity Karlovy pod vedením Martina Musálka. Výzkum probíhá v rámci projektu “Univerzitní centrum pro rozvoj lidské motoriky a ovlivňování motivace k pohybovým aktivitám”. A podstatná část výzkumných činností je věnována právě pohybu dětí. Karel Švátora a jeho tým se zaměřuje na problematiku vytváření pozitivního vztahu dětí k pohybovým aktivitám.Item Craving for exercise due to the disruption of daily routine by an earthquake(2025) İlbak, Ismail; Yasuntimur, Ahmet; Stojanovic, Stefan; Düz, Serkan; Rydzik, Łukasz; Čepička, LadislavObjectives: The research aimed to examine exercise cravings that arise from the disruption of daily routine resulting from the earthquake and the consequent mandatory absence from exercising at fitness centers. Study design: This study utilized the phenomenological design through qualitative research methods. Methods: The research sample comprises six individuals aged between 22 and 29 years. They were selected using the criterion sampling method. Data was collected through semi-structured interviews, and thematic analysis was used to analyze the data.Results: Two different types of cravings were identified. The first type is related to exercise addiction, while the second type is related to anxiety-induced cravings. Conclusions: Exercise craving manifests in two ways. The first type originates from exercise addiction, emerging when an individual with exercise addiction experiences a lack of exercise. With a more clinical dimension, the second type arises from the inability to engage in training for uncontrollable reasons.Item The relationships between ACTN3 rs1815739 and PPARA-α rs4253778 gene polymorphisms and athletic performance characteristics in professional soccer players(2023) Bulgay, Celal; Čepička, Ladislav; Dalip, Metin; Yildirim, Selin; Ceylan, Halil; Yilmaz, Ozlem; Ulucan, Korkut; Badicu, Georgian; Cerit, MesutBackground Current research on athletic performance focuses on genetic variants that contribute significantly to individuals' performance. ACTN3 rs1815739 and PPARA-a rs4253778 gene polymorphisms are variants frequently associated with athletic performance among different populations. However, there is limited research examining the pre-and post-test results of some variants of athletic performance in soccer players. Therefore, the presented research is to examine the relationships between the ACTN3 rs1815739 and PPARA-a rs4253778 gene polymorphisms and athletic performance improvement rates in adaptations to six weeks of training in elite soccer players using some athletic performance tests.Methodology Twenty-two soccer players between the ages of 18 and 35 voluntarily participated in the study. All participants were actively engaged in a rigorous six-day-a-week training program during the pre-season preparation period. Preceding and following the training program, a battery of diverse athletic performance tests was administered to the participants. Moreover, Genomic DNA was extracted from oral epithelial cells using the Invitrogen DNA isolation kit (Invitrogen, USA), following the manufacturer's protocol. Genotyping was conducted using real-time PCR. To assess the pre- and post-test performance differences of soccer players, the Wilcoxon Signed Rank test was employed.Results Upon analyzing the results of the soccer players based on the ACTN3 genotype variable, it was observed that there were no statistically significant differences in the SJ (Squat Jump), 30m sprint, CMJ (Counter Movement Jump), and DJ (Drop Jump) performance tests (p > 0.05). However, a statistically significant difference was identified in the YOYO IRT 2 (Yo-Yo Intermittent Recovery Test Level 2) and 1RM (One Repetition Maximum) test outcomes (YOYO IRT 2: CC, CT, and TT, p = 0.028, 0.028, 0.008, 0.000, respectively; 1RM: CC, CT, and TT, p = 0.010, 0.34, 0.001, respectively). Regarding the PPARA-a genotype variable, the statistical analysis revealed no significant differences in the SJ, 30m sprint, CMJ, and DJ performance tests (p > 0.05). Nevertheless, a statistically significant difference was observed in the YOYO IRT 2 and 1RM test results (YOYO IRT 2: CC, CG p = 0.001, 0.020; 1RM: CC, p = 0.000)Conclusions The current study demonstrated significant enhancements in only YOYO INT 2 and 1RM test outcomes across nearly all gene variants following the six-day-a-week training program. Other performance tests, such as the 30m sprint, SJ, CMJ, and DJ tests did not exhibit statistically significant differences. These findings contribute novel insights into the molecular processes involving PPARA-a rs4253778 and ACTN3 rs1815739 that underpin enhancements in endurance (YOYO INT 2) and maximal strength (1RM) aspects of athletic performance. However, to comprehensively elucidate the mechanisms responsible for the association between these polymorphisms and athletic performance, further investigations are warranted. It is thought that the use of field and genetic analyses together to support each other will be an important detail for athletes to reach high performance.Item Development of specific strength skills of upper limbs due to targeted movement intervention in judokas in categories U12 - U16(2023) Knappová, Věra; Pešek, Petr; Marek, PatriceThe presented work deals with the issue of grip strength and its development in the specific environment of combat sports. The research investigation compared the state of strength skills of U12-U16 judokas pre and post targeted movement intervention aimed at grip strength development. Probands were measured with a battery of 3 tests targeting upper limb strength skills and exposed to a targeted movement intervention over a 4-month period to stimulate the development of strength skills central to success in the sport. After the movement intervention, the boys' group showed statistically significant improvement in all tested parameters. Grip strength, paradoxically, improved mainly in the non-dominant upper limb.Item Vitamin D a pohybový systém (1. část)(2023) Votík, Jaromír; Novák, Jaroslav; Topolčan, OndřejPříspěvek pojednává o významu vitaminu D pro lidský organismus a jeho pohybový systém.Item The effect of controlled movement imaginary on performance in a modified 7-metre shot test of elite female handball players(2024) Benešová, Daniela; Drozdová, PetraMovement imagery may have a favourable influence on subsequent movement performance. As a result of creating a multi-modal movement image in the mind, there are activated specific brain centres that are identical for both movement planning and actual movement action. The objective of our experiment was to find out whether a single ideomotor intervention can influence the accurate execution of a known movement skill. The research sample consisted of adult female handball players who participate in the highest Czech handball competition. We tested the movement skill in a modified 7-metre shot/throw test developed by us. The research sample was randomly divided into the experimental group and the control group. The testing involved a pretest and a posttest. It was repeated two times over the period of 2 months. The players assigned to the experimental group had significantly better performance in the posttest of both measurements in the modified test.Item Relationship of gender, dimensions of temperament, and bimanual coordination(2024) Benešová, Daniela; Kalistová, Petra; Fajfrlíková, Tereza; Švátora, KarelBimanual coordination is used in everyday life activities and is a part of work-related skills, sports, and leisure time activities. Dynamics of experiencing is characterized by the dimensions of extraversion and neuroticism, which are believed to be brain correlates. Aim of Study. The objective of this study is to determine whether temperament characteristics and gender have any effects on performance in a test of bimanual coordination. Material and Methods. The research sample consisted of 193 participant, 86 of them were women (45%) and 107 were men (55%). All the participants were university students with an average age of 21.6 years ± 1.76. The Eysenck’s Personality Inventory (EPI) was used to determine extroversion and neuroticism levels, while the Supportive Drawing Test (SDT) was employed to assess a level of bimanual coordination.Results. In the SDT, the men demonstrated significantly better performance than the women. These differences were also validated by the level of substantive significance. The analysis of variance did not show any differences in the SDT performance in the extraversion dimension. However, in the dimension of neuroticism, significant intergroup differences have been observed. Labile participants performed more poorly on the SDT than neuropsychiatrically stable and ambivalent ones. The women showed a higher median of neuroticism (MdnW = 11) than the men (MdnM = 9). Among the female participants, 25.6% exhibited neuropsychiatric lability, while only 14.9% of the men belonged to the labile group. Conclusions. The results of the SDT showed no difference between the groups of labile men and labile women.Item ProCit o autismu(2021) Knappová, VěraJiž jedenáct let v Plzeňském kraji působí Občanské sdružení ProCit, z.s.

This study aims to: (1) examine and compare the benefits and barriers of walking to school perceived by adolescents and their parents within the whole sample, (2) and based on adolescents' modes of commuting to school (walking and using motorized transport). Methods: Third grade adolescents at secondary education from 4 Spanish cities and their parents participated in the PACOyPACA cross-sectional study. All completed a benefits and barriers questionnaires regarding to adolescents walking to school. Descriptive statistics, paired samples t-test and Wilcoxon test were used to identify differences between adolescents' and their parents' perceived benefits and barriers. Results: 466 adolescents (age: 14.86 ± 0.51 years old) and 499 parents (age: 48.00 ± 5.42 years old) entered the study. Results showed that 209 (44.8%) adolescents walked to school, and girls did it significantly less (p < 0.01). Benefits were perceived as significantly more important for parents than for adolescents (p < 0.001) in all cases and regardless of the modes of commuting. As for barriers, adolescents cared significantly more about saving time (p < 0.001), and parents significantly gave more importance to traffic danger and additional planning to walk to school (p < 0.001). When adolescents walked to school, they were significantly more concerned than parents about saving time (p < 0.01), weather and walking being a hassle (p < 0.05), and parents reported traffic as a significantly higher concern than adolescents (p < 0.05). When adolescents commuted to school by motorized transport, they significantly gave more importance than parents to saving time (p = 0.001), and parents reported significantly higher values for additional planning to walk to school (p < 0.001), lack of continuous paths (p < 0.01), distance, weather, and traffic (p < 0.05) than adolescents. Conclusions: Perceived benefits were important for adolescents and parents, regardless of the modes of commuting to school. Adolescents and their parents presented higher concerns when adolescents commuted to school by motorized transport.Item Agreement with COVID-19 Conspiracy Theories Has Poor Temporal Stability(2024) Pišl, Vojtěch; Volavka, Jan; Kavalířová, Gabriela; Vevera, JanLow temporal stability may complicate the interpretation of survey measures of conspiracy theories (CTs). Current study examines the stability of endorsement of CTs on a popular set of items addressing COVID-19-related CTs. An online survey tapping two CTs about COVID-19 was administered to 179 students of general medicine. The same items were presented twice in March 2022 and once in May 2022. The mean endorsement of the CTs did not differ between March and May. The correlation between answers provided in March and May was low (.5 < r < .7). Most of those reporting agreement with CTs in March reported disagreement in May. Conspiracy believers' responses did not change between two measurements in March but were different in May, suggesting that the low temporal stability was due to situational factors rather than erroneous or random answers. Poor temporal stability of responses endorsing CTs may problematize interpretation of survey data. Respondents' endorsement of CTs may be affected by situational factors, inflating agreement with CTs, and correlations with other survey-based measures.Item Change of direction and linear speed relation to functional ability and joint mobility in Polish U19 volleyball and basketball 3 × 3 national teams(2024) Czyznielewska, Zuzanna; Gabryś, Tomasz; Yagin, Fatma Hilal; Čepička, LadislavThe purpose of this study was to determine the extent of differences in the level of change in linear speed and velocity in the modified change of direction test (COD) and to determine the relationship between speed deficits resulting from changes of direction and functional performance between groups of Polish U19 Volleyball National Team and Polish Women's Basketball 3 × 3 National Team. A total of 23 athletes: 12 volleyball players (age: 18 ± 0 years; body height: 183 ± 7 cm; body weight: 70 ± 8 kg) and 11 basketball players (age: 26 ± 4 years; body height: 180 ± 6 cm; body weight: 73 ± 10 kg) participated in the study. Athletes were tested for the following measures: Functional Movement Screen test (FMS), dynamic balance test Y-Balance, joints range of motion measurements, maximal sprint test (14 m), modified COD test (14 m) and change of direction deficit (CODD). A value of p < 0.05 was considered statistically significant. There was no significant correlation between sprint and CODD results in basketball team. In volleyball team there was a positive and significant correlation between COD, sprint and CODD. There was a negative and significant correlation between Y-Balance scores and sprint test results in the basketball team. Basketball team had a positive significant correlation between hip rotations and COD results. There was a negative significant correlation between shoulder movements and COD and CODD results in volleyball team.Item A Cross-Cultural Adaptation of the Czech Version of the Developmental Coordination Disorder Questionnaire: The Content Validity Part(2024) Vlasáková, Nikol; Musálek, Martin; Čepička, LadislavThe Developmental Coordination Disorder Questionnaire (DCDQ) is a widely used parent questionnaire for screening motor coordination disorders in children aged 5–15 years. Despite increasing motor difficulties in children, a validated version is lacking in Central Europe. In addition, previous studies pointed out that several DCDQ items were shown to be problematic in different cultural environments. We found that the majority of these studies did not assess the item’s content validity approach for keeping the semantic form and linguistic intelligibility of the original items. Therefore, this study aimed to translate the DCDQ, determine the content validity of items, and adapt the DCDQ for Czech children aged 6–10 years, where the identification of motor difficulties is crucial. Back-translation was employed, and face validity was consulted with linguistic experts and occupational therapists. A sample of 25 bilingual parents and practitioners evaluated the translated version, with content validity assessed using the Content Validity Ratio coefficient (CVR). Initial CVR scores ranged from 0.6 to 1.0. Lower scores were found for items 14 and 15, which were shown to be problematic in previous studies. The reason for the lower content validity in these items was due to double negation. Following linguistic modifications, the CVR values improved (range: 0.87–1.0), indicating content and semantic stability. Our findings underscore the importance of considering content validity and language specificity, including issues like double negation, during cross-cultural questionnaire validation to mitigate potential psychometric concerns in the future. The adapted Czech version exhibits significant content validity, thereby warranting further validation of its psychometric properties.Item Psychomotor determinants of children's sports talent for team sports: a case study of mini-volleyball athletes(2023) Klocek, Olga; Lipowska, Malgorzata; Klocek, Tomasz; Čepička, Ladislav; Spieszny, MichalBackground: Psychomotor predispositions significantly impact the effectiveness of the training process and achievement in team sports. The aim of the present study was to assess the level of psychomotor indices in 12-year-old children who achieved outstanding sports successes in mini-volleyball. Materials and Methods: The results of the tests conducted on the six medalists of the Polish Mini-Volleyball Championships were qualified for analysis. To assess psychomotor indices, a battery of computer tests was used; the following were measured: simple reaction time, choice reaction time, eye-hand coordination, divisibility of attention, and spatial orientation - accuracy of perception. Results: Four of the six mini-volleyball medalists achieved an outstanding level of psychomotor development; the remaining two children showed an average level on the scale of sports norms. Most often, young champions are distinguished by a short choice reaction time and outstanding (against the background of sports standards) orientation indices: accuracy of perception, and divisibility of attention. Conclusion: The analysis confirmed, as suggested in previous publications, a significant relationship between outstanding sports talent and the level of selected psychomotor and coordination indices in children practicing volleyball.Item Factor Validity and Generic Reliability of the Developmental Coordination Disorder Questionnaire in the Czech Population(2023) Vlasáková, Nikola; Musálek, Martin; Čepička, LadislavThe Developmental Coordination Disorder Questionnaire (DCDQ) is widely used as a brief parent questionnaire designed to screen for motor coordination in children, aged 5 to 15 years. There is no validated version of the DCDQ for the Central Europe, which could help for first catch of children with motor difficulties, whose amount has been seriously raised. In addition, the World Health Organization recommends the cross-cultural validation of existing instruments, for Loir costs and time consuming, and the availability of instruments in several languages enables therapists to use validated tools with non-English speaking clients. The aim of this study was to validate the DCDQ in the Czech culture in a population of Czech parents whose children were aged six to ten. Using data from 651 Czech parents of children (six to ten years; 7.8 & PLUSMN; 0.8 years), confirmatory factor analyses (CFA) were used. The goodness-of-fit indices CFI = 0.94, TLI = 0.93, and RMSEA = 0.08 supported the original three-factor model of the DCDQ. In addition, the factor loadings of each question discovered in Czech DCDQ were non-significantly different from the original DCDQ. Furthermore, we also found strong between factor correlation; general coordination and control movement r = 0.87 probably measure the same underlying construct. Even though this is in conformity with original DCDQ structure, we suggest that responses in these two DCDQ factors might have violated the local independency and, therefore, could bias the final score. The generic reliability of the individual factors was acceptable and ranged from McDonald & omega; 0.83-0.88. Results from this study suggest that cross-validated version of the original DCDQ can be considered as sufficiently valid and reliable clinical screening tool for children who have coordination challenges for Czech children aged six to ten.Item Vitamin D a pohybový systém (2. část)(2024) Votík, Jaromír; Novák, Jaroslav; Topolčan, OndřejPříspěvek pojednává o významu vitaminu D pro hráče fotbalu s doporučeními k suplementaci vitaminem D.Item Is early or late biological maturation trigger obesity? A machine learning modeling research in Turkey boys and girls(2023) Gülü, Mehmet; Yagin, Fatma Hilal; Yapici, Hakan; Irandoust, Khadijeh; Dogan, Ali Ahmet; Taheri, Morteza; Szura, Ewa; Barasinska, Magdalena; Gabryś, TomaszBiological maturation status can affect individual differences, sex, height, body fat, and body weight in adolescents and thus may be associated with obesity. The primary aim of this study was to examine the relationship between biological maturation and obesity. Overall, 1,328 adolescents (792 boys and 536 girls) aged 12.00 +/- 0.94-12.21 +/- 0.99 years, respectively (measured for body mass, body stature, sitting stature). Body weights were deter-mined with Tanita body analysis system and adolescent obesity status was calculated according to the WHO classification. Biological maturation was determined according to the somatic maturation method. Our results showed that boys mature 3.077-fold later than girls. Obesity was an increasing effect on early maturation. It was determined that being obese, overweight and healthy-weight increased the risk of early maturation 9.80, 6.99 and 1.81-fold, respectively. The equation of the model predicting maturation is: Logit (P) = 1/(1 + exp. (- (-31.386 + sex-boy * (1.124) + [chronological age = 10] * (-7.031) + [chronological age = 11] * (-4.338) + [chronological age = 12] * (-1.677) + age * (-2.075) + weight * 0.093 + height * (-0.141) + obesity * (-2.282) + overweight * (-1.944) + healthy weight * (-0.592)))). Logistic regression model predicted maturity with 80.7% [95% CI: 77.2-84.1%] accuracy. In addition, the model had a high sensitivity value (81.7% [76.2-86.6%]), which indicates that the model can successfully distinguish adolescents with early maturation. In conclusion, sex and obesity are independent predictors of maturity, and the risk of early maturation is increased, especially in the case of obesity and in girls.Item Athletic performance, sports experience, and exercise addiction: an association study on ANKK1 gene polymorphism rs1800497(2023) Bayraktar, Isik; Čepička, Ladislav; Barasinska, Magdalena; Kazan, Hasan Huseyin; Zorba, Erdal; Ergun, Mehmed Ali; Özgür, Eken; Ceylan, Halil Ibrahim; Bulgay, Celal; Gabryś, TomaszIntroduction: Exercise addiction is a phenomenon being able to affecting the athletic performance. The gene, ANKK1 and the polymorphism M_178510.2:c.2137G > A (rs1800497) has been linked to the exercise addiction.However, further studies on diverse populations and sport branches are needed to totally explore the possible association of this polymorphism with the athletic performance. Thus, the present study aims to decipher any possible relations of the rs1800497 polymorphism with the athletic performance/personal best (PB) and sport experience of elite athletes. Methods: Sixty volunteer elite athletes (31 sprint/power and 29 endurance) and 20 control/sedentary participated in the study. The polymorphism was genotyped using whole exome sequencing approach and PB were determined according to the International Association of Athletics Federations (IAAF) score. Results: Our results underlined that there were not any significance differences for both allele and genotype frequencies between the groups in terms of athletic performance, although the frequency of allele G was higher (p > 0.05). Nevertheless, sport experience significantly associated with the rs1800496 polymorphism (p < 0.05). Discussion: In conclusion, genotype G/G could be inferred to be linked to the higher sport experience and athletic performance. Still, further studies with higher number of participants are needed to conclude the association of this polymorphism with athletic parameters.
