Introduction: The selection into the National Hockey League (NHL) is based on criteria reflecting job analysis of a professional ice hockey player and the requirements of the game. Only few Czech elite ice hockey players succeed to participate in NHL and their number is decreasing in the last decade. Aim of Study: The aim of the study was to find out and evaluate the level of anaerobic readiness of Czech hockey forwards and defenders playing in the NHL and to compare their anaerobic performance with that in elite national hockey players from the Czech extra-league. Material and Methods: Results of 30s Wingate anaerobic test obtained in 26 forwards and 16 defenders, Czech hockey players from the NHL (from 2001/2002 to 2015/2016 seasons) were compared with the reference values of elite Czech ice hockey players. The comparison was based on the mean values, rate of dispersion, and effect sizes were calculated using Cohen's d coefficient. Results: In forwards, both absolute and relative values of peak power (PP) and anaerobic capacity (AnC) found in Czech players in NHL were higher (d>1) than in elite Czech national players. In defenders, only the value of AnC relative to body mass showed small effect (d=0.36), but absolute and relative values of PP and absolute value of AnC were higher (d>1) than in elite Czech national players. Conclusion: The results of the study indicate that anaerobic readiness evaluated by 30s Wingate test may be, besides dominant on-ice skills, one of the criteria for entry to the top ice hockey competition.

Introduction: The aim of this study is to examine and evaluate the effects of long-term stress on muscle and heart biomarkers after completing a 100 km ultramarathon. Material and Methods: Venous blood samples of nine runners (average age 38.8±10.2 years), who successfully finished a 100 km ultramarathon at an elevation of 3130 m, were examined before the start, at the finish line immediately after the run, one day after the run and then after 5 and 10 days. Clinical, laboratory, and somatometric data were obtained from all measurements, and biomarkers: aspartate aminotransferase (AST), cortisol (COR), troponin T (cTnT), creatine kinase (CK) and C-reactive protein (CRP). Also, their training experience and ultramarathon experience was monitored. Discovered values were further analyzed with the use of t-test a ω2 (ω2≥0.1), and Spearman’s rank correlation coefficient (r) at the significance level of p<0.05. Results: The average finish time of the runners was 13:55:40 (min: 12:12:35, max: 16:52:02). After finishing the ultramarathon, runners showed an average weight loss of 2.4 kg (p<0.05). The results show that hematological changes were caused by physiological stress and long-term physical load. The values of all monitored biomarkers showed a significant exceeding of the normal values immediately after the race in 8 competitors out of 9. The values of cTnT showed an increase of more than 50 % (pre-race: 8.2±2.3, post-race: 34.22±25.9 ng/l, max=98 ng/l). After 24 hours, however, this condition had returned to the normal values for all participants. The results show that the AST hepatic enzymes significantly correlated with the training experience (r=-0.41, p=0.043), the total number of kilometers run per year (r=-0.45, p=0.04) and the achieved finish time (r=0.67, p=0.001). At the same time, athletes who had the best finish time achieved lower CRP values (r=0.74, p=0.023) and cTnT values (r=0.49, p=0.040). The study found that the competitors who had the longest experience with ultramaraton had the lowest cTnT (r=0.44, p=0.050). Conclusion: Long-term physical stress is associated with metabolic and cardiovascular changes. Blood abnormalities found in our study suggest that due to long-lasting extreme stress, heart exhaustion may occur. However, these changes did not last long and after a few days they returned to the normal values for all runners.

Anxiety trait is a relatively stable personality trait, which refers to the differences between individuals in terms of their tendency to experience state anxiety in response to the anticipation of a threat. Regular sport activity may influence some aspects of emotional adjustment in positive way and so on an individual ́s well-being. The aim of the study is to find out the possible differences in the level of separate dimensions of personal well-being of men and women with increased anxiety trait level, regarding their sport activity. The research sample consists of 74 respondents in late adolescence (30 men: athletes n=12, nonathletes n=18; 44 women athletes n=18, nonathletes n=26). We have used the standardized STAI questionnaire to determine the level of anxiety trait and standardized BDP questionnaire to determine the level of personal well-being (with respect to its two positive dimensions and three negative dimensions). The results have showed that male athletes demonstrated a significant higher level of positive attitude towards life (p=0.01) and a significantly lower level of awareness of problems (p=0.04) and depressive mood (p=0.03) as male nonathletes. Female athletes demonstrated a significant higher level of positive attitude towards life (p=0.02) and selfevaluation (p=0.00) while a significant lower level of depressive mood (p=0.04) as female nonathletes. Our findings indicate that regular sport activity can be a suitable instrument to increase personal wellbeing (in some aspects of well-being) of women and men with higher level of anxiety trait.

Introduction: Achievement goals assumes that govern achievement beliefs guide subsequent decision making and behavior in achievement contexts. The purpose of the study was to analyze the goal perspectives (task and ego orientation) based on personal and disability-related characteristics. Material and methods: The participants in this study were 140 people with physical disabilities (n=107 men, and n=33 women. Their age ranged from 14 to 67 years (M=35.31, SD=10.67). The participants filled the Task and Ego Orientation in Sports Questionnaire (TEOSQ). In addition following factors were put into analysis: gender, age, family status, education, occupational status, disability [congenital versus acquired], type of disability [spinal cord injury, brain palsy, amputation, poliomyelitis, muscular dystrophy and other type], type of activity [sport activities – competitive versus recreational – and any activity], type of sport [team versus individual sports], type of experience [resistance, strength and skills], and type of games [Paralympic, European, National and Sectional]). Results: Results showed that people with physical disabilities who mainly take part in physical activities manifest a high disposition of task orientation (M=3.96, SD=0.67) and moderate ego orientation (M=2.61, SD=0.82) in physical activities settings. In addition, the results revealed that personal characteristics, type of activity, and athletic experience play a small role in the existence of individual differences in goal perspectives. Conclusions: The people with physical disabilities, mainly athletes, show a predisposition towards task orientation on achievement settings in physical activities, and the personal characteristics as exercise form (competitive, recreation, no exercise), and athletic experiences effect in the existence of individual differences in goal perspectives.

Introduction: Isometric and isokinetic dynamometers are mainly used for assessment of strength and endurance of core muscles. However, muscle power represents a more appropriate variable for evaluating of athlete performance that involve dynamic movements of the trunk. This study estimates test-retest reliability of trunk rotational power and velocity over a 1-week interval using the FiTRO Torso Isoinertial Dynamometer. Material and Methods: A group of 32 physically active men performed 5 trunk rotations to each side while seated with a barbell of 1 kg or 20 kg placed on their shoulders. Results: Results showed that assessment of peak and mean velocity in the acceleration phase of trunk rotations with 1 kg provides reliable results (ICC = 0.94 and 0.92 respectively, SEM = 7.0% and 7.3% respectively). However, peak and mean values of velocity and power obtained during trunk rotations with a weight of 20 kg should be interpreted with caution (ICC < 0.80, SEM > 10%). Conclusions: Such an assessment of trunk rotational power and velocity can be used in practice, however with a limitation of performing trunk rotations in a seated position and using lower loads.

Introduction: This case study applied the Dahn Taekwondo Spondylitis Improvement Program (DTSIP) to a 30-year-old male with ankylosing spondylitis five times a week for 28 weeks. Materials and Methods: A 32-year-old male with ankylosing spondylitis underwent the Dahn Taekwondo Spondylitis Improvement Program (DTSIP), an amalgamated program of standard Western medicine practices and complementary and alternative medicine (CAM) exercises based in the oriental medicine practices of yoga and taekwondo. The subject performed the DTSIP 5 times a week for 90 minutes for 28 weeks. Results: First, blood C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and platelet levels decreased by approximately 29-71%. Second, blood leukocyte counts decreased by about 11%. Third, as a result of Bath Ankylosing Spondylitis Metrology Index (BASMI) measurement, tragus to wall (TWD), lumbar side flexion (LSF), LF (lumbar flexion), and intermalleolar distance (IMD) were improved substantially. The students’ cervical vertebrae and thoracic and lumbar vertebrae ranges of motion were additionally improved. The range of motion of the shoulder and hip joint improved. Conclusions: Therefore, the DTSIP seems to have a positive effect on the inflammation, immune functions, and spine and joint range of motion in the subject of this case study. Future studies are required with a wider sample population to validate these results.

Introduction: The purpose of the study was to determine the effects of different sports on body fat and lean body mass in pubescent girls. Material and Methods: The sample of 40 girls (12 ± 1.2 years of age) were divided into 4 groups: 10 volleyball players, 10 basketball players, 10 swimmers, and 10 girls formed the control group. Body height was measured using portable stadiometer. We used InBody 230 to measure body mass, body mass index, fat mass, lean mass, visceral fat, and sum of skeletal muscles. The measured variables were evaluated using the Body-vision program and Statistica 12.0 cz. For normal distribution we used Shapiro-Wilk normality test. The differences between the groups were determined by Kruskal-Wallis test, p<0.05. Results: We found statistically significant differences in fat mass between the groups of swimmers and the control in the body fat (10.62%; p= 0.033) and fat mass in upper limbs (1.42 kg; p= 0.027). Statistically significant difference was found between the group of swimmers and volleyball players in the lower limbs fat mass (2.43 kg; p= 0.045). Furthermore, statistically significant difference in lean mass was found between the volleyball players and the control in the weight of the lower limbs muscle mass (3.59 kg; p= 0.047). Conclusions: Our findings show that sports such as volleyball, basketball, and swimming provide appropriate development of lean mass in pubescent girls. We may conclude that pubertal girls practicing sports have lower body fat mass and higher lean body mass compared to youth who do not practice sports.
