Background: Autism spectrum disorders (ASD) are associated with gross motor development delays and a limited ability to imitate human movements. Early intervention in the field of motor skills is crucial both from the point of view of the need for comprehensive care for these children and to increase their quality of life. Diagnostic evaluation tools for use in practice are a necessary prerequisite for targeted intervention programs. The Test of Gross Motor Development–Third Edition (TGMD-3) is declared for use in children with ASD (Ulrich, 2019). The TGMD-3 was developed in the USA and consists of two subtests – Locomotor and Ball skills. The Ball skills subtest contains culturally different elements such as strike stationary ball and underhand throw, performed according to US practice. For these reasons, modifications have been made in some countries in the European socio-cultural environment (Wagner et al., 2017) that do not include these elements typical of the US environment. The aim of this study was 1) to record and describe the reactions of children with ASD to culturally different elements in the ball skills subtest in the TGMD-3 motor test and 2) to compare their evaluation with other items of this subtest. Methods: This pilot study included 16 children with ASD aged 7-10 years. A total of 1 girl and 15 boys were evaluated by the TGMD-3 motor test using visual support. (Allen et al., 2017) Four independent examiners assessed participants' physical performance by following the instructions of the Examiner's Manual Test TGMD-3 3. Results: The results of the study are presented in the form of case studies of individual participants, which allow for further research in this heterogeneous population of children with ASD with better descriptive and comparative possibilities than statistical numerical expression. The limited ability to imitate, which is characteristic of children with ASD, is likely to have a significant effect on culturally dissimilar designs, especially the Underhand throw. The two-hand strike of a stationary ball's culturally different skill was very motivating for children with ASD aged 7-10. Conclusion: The limiting factor for generalization to the entire population of children with ASD aged 7-10 in the Czech socio-cultural environment is their small number and heterogeneity, which were affected by restrictive measures during the Covid-19 pandemic. Further research using the TGMD-3 instrument in the Czech population has the potential to expand diagnostic methods in the field of motor skills and contribute to the possibilities of early physical intervention in children with ASD.

The relationship between sports and sustainability has been recognized 30 years ago but the impacts of developing sports remain unknown. By combining a scoping review with the Delphi method, our study uncovers the positive and negative impacts of kiteboarding on the social and natural environment. In addition to expected impacts such as improving the fitness of an individual and generating conflicts among kiteboarders and beachgoers, our findings reveal surprising impacts, most of which positive because the experts primarily regard kiteboarding as an environmentally friendly sport. The only severe environmental impact identified by the experts was the lack of recycling of kiteboarding products. Despite the widespread perception of kiteboarding as a sport that contributes to climate change, the experts failed to reach a consensus on the severity of the carbon footprint of kiteboarders, who travel to distant locations. This study highlights the importance of assessing the environmental effects of individuals’ sports.

Objectives: The objective of the evaluation was to study and determine the impact of eight weeks of aerobic training (AT) on liver enzymes and changes in hematological profile in children with leukemia. Methods: This is a semi-experimental and applied study. Statistical samples include 24 children aged 7 to 10 years that referred to hospital and were divided randomly into two control (n=12) and experimental (n=12) groups. Eight-week AT with 40 to 70 percent of heart rate reserve, three sessions per week, no exercise training program was observed in the controls during the study. We measure Liver enzymes such as Aspartate aminotransferase (AST) and alanine aminotransferase (ALT), Hemoglobin (Hb), White Blood Cells (WBC), platelets (PLT), and bilirubin. Data analysis using a paired t-test and analysis of covariance was performed with software SPSS version 20. Results: The results showed that moderate-intensity AT has a significant effect on hemoglobin and liver enzyme levels and a significant increase in Hb (p<0.05) and significant reduction the ALT and AST (p<0.05) whereas there was no significant influence on WBC, ALT, and bilirubin (p>0.05). Conclusion: AT may accelerate the oxygen supply and reduce liver damage caused by medications in children diagnosed with leukemia without having corrupting effect on PLT, bilirubin, and safety factors.

Purpose:The study aims at identifying the relationship between grit, coach leadership style, sports motivation and athlete’s satisfaction. Methods: Correlational studies are used to see the relationship between grit, coach leadership style, sports motivation and athlete’s satisfaction. Participants involved in this study are athletes in rowing (n=30). Grit, coach leadership style, sports motivation and athlete's satisfaction was assessed by Questionnaire. Nonparametric calculation through Spearman's Rank Correlation was used to test the relationship between the variables. Results: This study showed several results. First, there was a positive relationship between grit with sports motivation and athlete’s satisfaction (p<0.05). Second, there was a positive relationship between coach leadership style with sports motivation and athlete’s satisfaction (p<0.05). Conclusions:Thus, our research highlights the importance of a trainer's girt and leadership style to create a positive relationship with sports motivation and satisfaction in athletes in carrying out training activities.

The purpose was to investigate whether runners who do not squat their body weight once will not be overloaded with a weight vest with a load of 5% of BW and will not maintain 95% intensity across ten repetitions of a 20-meter sprint. Eight adult female students (24,05±1,15 years old; body height 168±4,24 cm; body weight 60,39±5,53 kg) from the faculty of sports studies at Masaryk University in the Czech Republic participated in this study. Categories were: 1 = NBW (1RM in the squat is relative body weight ± 5 kg), 2 = LBW (1RM in the squat is lower than BW-5 kg) and 3 = HBW (1RM in the squat is higher than BW +5 kg). The measurements took place on three different days, each day running with another experimental condition: free sprinting, weighted vest sprinting with a 5% load of BW, and weighted vest sprinting with a 5% load of 1RM squat. With a weight vest with resistance at the level of 5% of body weight, during 49 sprints, the intensity decreased by a maximum of 4.82% (participant 4, NBW group, 1st run). Although, with weight vest resistance at the level of 5% of the 1RM back squats, during 68 sprints, the intensity decreased by a maximum of 6.59% (participant 1, NBW group, 8th run). It seems that the level of strength abilities of the lower limbs did not play a role in this, we can calculate 5% intensity from both BW and 1 RM squat. Since the HBW group could maintain the required intensity even at significantly higher weights than 5% BW, further research with a larger research sample is needed.

The main aim of this paper is manifested in the hypothesis that there is a statistically significant correlation between the length of an active wrestling career and selected attitudes and behaviours caused by the COVID-19 virus pandemic. The sample of respondents (N=131) consists of international wrestlers (average age 22.32±5.08 years) from all competition categories (seniors, senior juniors U23, juniors and cadets). The collected survey data were systematized based on obtained answers and numerical values and according to the instructions for interpretation of answers analysed with particle frequencies and descriptive statistics. Correlation analysis proved statistically significant negative association (r = - 0,19) between the length of an active wrestling career and the behaviour of wearing a protective mask during the COVID-19 virus pandemic. Observing all age groups, attitudes indicate concern about the infection of acquaintances, and the behaviour of wrestlers emphasizes the importance of washing hands, wearing masks, and using disinfectants. Wrestlers are also aware of the dangers of the virus for their careers and are informed and follow the instructions of experts.

The aim of this research is to determine whether a larger number of injuries in the team affects the final competitive achievement of clubs in the 1st Croatian Football League. Data on injuries in training and matches were collected using UEFA's Injury Study Questionnaire. 340 players (in all 10 clubs) participated in the research. The Chi-square test was used for non-parametric tests while logistic regression analysis was used to correlate the independent and dependent variables. The hypothesis that clubs with lower rankings will have statistically significant more injuries has not been confirmed (p<0.05), but this difference (although not statistically confirmed) still exists between clubs that finished the championship at the top five compared to the low five clubs.

The purpose of the study was to select or create a test that will be a suitable alternative to the Cooper 12-minute test for a large number of adults who are not able to undergo the running test. A literature review of aerobic capacity indicators and endurance fitness tests on the C2 rowing machine was prepared. The result of extensive research is the design for a simple test with a set duration, when the tested person should try to cover the greatest possible distance (i.e. maximum effort). To verify this, a pilot study was conducted using the new test and collected initial reference values to assess the physical fitness of individuals. A total of 323 students of the University of Defence (270 males, 53 females), aged 20.9±1.82, took the test. The endurance fitness indicators are the distance covered (s, m) and the average power (P, W). Statistical tests (t-test, correlation analysis, non-linear regression analysis, the Kolmogorov–Smirnov difference test, the Spearman correlation) were used to analyse differences and relationships between variables. The results of the pilot study demonstrate the applicability of the created test under required conditions. Significant differences between males and females confirm the necessity of evaluating test results separately for each gender. Low correlations between fitness indicators to body weight and height do not support the need to use relative fitness indicators (per kg of body weight). The results of the study provided initial reference values for individual assessment of aerobic fitness.

Olympic weightlifting (OW) is sport with high strength and power demands where athletes need to explosively lift heavy weights. It is consisted of barbell lifting snatch and clean and jerk disciplines. In the strength and conditioning training, OW techniques are often used as a method for speed and power development. The aim of this study was to determine effects of 4-week OW training intervention on speed, agility and power performance among young recreational athletes. The sample of participants consisted of 12 Kinesiology students (average 23 years old). They attended the Olympic Weightlifting course. The training intervention lasted 4 weeks and with 3 training sessions per week in which participants practiced OW training based on learning OW techniques and auxiliary lifts execution. Before and after the intervention, measurement was conducted and included power, speed and agility tests. Squat jump (SJ), countermovement jump (CMJ) and drop jump (DJ) were used to estimated lower body power and medicine ball throw (MBT) for upper body power. Sprinting on 5 meters (S5) and 15 meters (S15) were conducted as power and speed tests, while 20 yards test (20Y) measured nonreactive agility performance. All variables were descriptively analysed and T-test for dependent samples was used to determine possible effects of training intervention. Results showed improvement in jumping capacities, with statistically significant difference noted only for CMJ (p>0.01). Upper body power and agility performance did not show any significant changes, while a decline in sprinting performance was found for both S5 (p>0.01) and S15 (p>0.01). While the results in jumping variables are expected and in accordance with current scientific knowledge, the results in sprint tests are somewhat confusing. Possible explanation for this can be found in the fact that the participants worked for four weeks the tasks that biomechanically are not similar to the structure of sprinting movement. This could suggest that athletes who want to improve their explosive speed capacities should include specific sprint stimuli in their training program in addition to OW training program. In the future, more variables and longer treatment duration need to be applied.

In the last 10 years, the Czech Republic has been struggling with a strong social policy, influenced by the active social policy of post-communist countries. See the article PROGRESSION OF SUPPORT FOR COMPANIES EMPLOYING PEOPLE WITH DISABILITIES, already published in IJMAS vol.8, issue 8. The implementation of people with disabilities on the labour market and in Czech companies is very important if we look at the fact that there is still a lack of workers to fully cover vacancies and a large mass of people who are partially able to work and their potential can only be used. The aim of this survey is to complement previous surveys and to be part of a large research on the issue of disability in the Czech Republic. An in-depth survey was used with the help of in-depth interviews with managers of diversity teams, corporate management and by the employees themselves in the corporations using a questionnaire survey. The sample consisted of 101 workers and 15 team leaders in 8 companies. The result is not a universal implementation methodology for a team leader to integrate a new/existing worker with a health disadvantage into the work team and measure his effectiveness in the team. The question remains how the implementation methodology can be applied outside the work environment, namely to teams of leisure activities of people with disabilities.
