    Opis:
    In this paper, we analyze data sets, collected from the public web sites, containing the finishers arrival times in five different half marathons. We focus on finding patterns in the arrival times distributions as well as on studying the differences between the female and male runners’ arrival times distributions. The main statistical tools used are Analysis of Variance and Kolmogorov - Smirnov test for identifying underlying distributions and for comparing distributions of two samples. The obtained results indicate that the dynamics of groups of female runners is different than that of male runners. Also, a meaningful factor for the sha pe of the distribution is time limit set by the races organizers.

    Opis:
    Triathlon is dev eloping very quickly nowadays. In our paper we are interested in cross triathlon. The road bike is replaced by the mtb mountain bike and the run is also done in the mountain. Triathlon is the endurance kind of sport where the AeT’s (aerobical threshold) a nd AnT’s (anaerobical threshold) level is the basic indicator of a sports performance. The curve of the both thresholds changes under the influence of a lot of factors during the year. We studied the influence of the running preparation on the aerobic and anaerobic threshold at the cross triathlon specialist during one year. We monitored the level, especially the changes in the sports performance during the ATC (annual training cycle). We valued the training proccess, the quantization of the training load and its influence on the triathlet’s performance with the intraindividual analysis.We gained the necessary data from the training diary and with help of the tests realized in the laboratory conditions .We detected the speed at the aerobic and anaerobic thr eshold by the running belt. Then we corelated them with the training parameters and we found out the addaction. We followed their actual influence on the performace and the influence of the training paramaters in the time intervals.

    Opis:
    The purpose of this study was to compare of two aerobic training methods on health-related physical fitness in 10 to 12 years old boys. Thirty-three male students (age 11.27±0.64 year, weight 40.58±9.03 kg, height 151.45±6.34 cm) were recruited from preliminary school and randomly were assigned into rope-jump training (n=12), running training (n=11) and control (n=10) groups. Due to the grouping, each for 8 weeks did the rope jumping or running. Before and after the 8-week training period, factors of health-related fitness, including flexibility, muscular endurance, aerobic power and fat Percentage of the subjects were measured. The results indicated a significant positive effect of rope-jumping training on aerobic power, muscular endurance and body composition and meaningful improvement of aerobic power and body composition by running training (p≤0.05). Due to increasing urbanization and lack of space in homes and schools, rope-jump training can be a good alternative rather than running for physical fitness promotion.

    Opis:
    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.

    Opis:
    Authors in their contribution deal with the issue of reactive and running agility in sport. Upon constructing the methods of research we assumed that players ́ performances in running agility (Illinois test) should increase with the age of soccer players. W e expected that we shall not prove this tendency in the level of reaction agility (FAC) with regard to the fact that performance in reaction agility is limited, besides motor, also by other prerequisites such as perception, state of receptors, sensoric and autonomous functions, spinal and supraspinal levels of motor system. We also expected that there will be no proved relationship between these tests ́ results in any age category. The level of performance in running and reactive agility increases with age; t he increase is smooth in running agility and cascaded in reactive agility starting with the 14 yrs. category. We also noted a downward tendency in the correlation between running and reactive agility with increasing age. This decline is most evident from t he 14 th year of age. The relationship between running and reaction agility was not observed in the study group from the age of 13. Coaches are recommended to switch over to the specific development of agility using the way of weakening anticipation ability of the player and to replace exercises with closed -loop skills by the ones of open -loop skills.
