Background and Study Aim. Hammer throwing is the most complex athletic throwing discipline with rotational trajectory and strong effect of several different forces that try to disable the projected throwing trajectory. Kinematic parameters are an important segment in the analysis of athletic disciplines, including hammer throw. They are an indicator of influence and often a difference between competitors of different or the same rank of the competition. The aim of the study was to determine the spatial and temporal differences of kinematic parameters between male and female elite hammers. Material and Methods. The study was conducted on sample of 16 Daegu World Championship finalists in 2011, to analyse differences in kinematic parameters between male and female throwers hammer. To obtain the required results, t-test for small independent samples was applied. Results. The data obtained in the study were given as Mean and Standard deviation. Statistically significant differences between male and female finalists were confirmed in the rate of ejection (t=3.684; p<0.004) and the speed of the fourth turn (t=4.396; p<0.002). The male finalists achieved an average ejection velocity of 27.91m/s and the female finalists 27.17m/s, with an average turn speed of 4.67m/s (male) and 4.03m/s (female). Conclusions. The research has shown that significant differences were made between male and female finalists in Daegu in 2011. The causes of differences can be found in length of training, different training process, technical mastery, competitor experience, morphological profile, motor and anatomical structures, movement technique and biomechanical parameters, which were not taken into the research.

The purpose of this study was to examine the relationship between leg muscle power, balance, coordination, and shooting skills in soccer. Participants in this study used 89 soccer athletes with an age range of 15-18 years (M = 17.6; SD: 1.30). The research instrument used a coordination test (soccer wall volley test), balance test (modified bass test), leg muscle power (standing long jump test or broad jump), and shooting skills test. Data collection techniques, namely by measuring tests and measurements by the implementation procedure. Data analysis in this study was using Pearson correlation and regression analysis with the help of the IBM SPSS 24 application. The results showed that: 1) There was a relationship between leg muscle power and shooting ability using instep; 2) There is a relationship between balance and the ability to shoot using the instep; 3) There is a coordination relationship with the ability to shoot using the instep; and 4) There is a relationship between leg muscle power, balance, and coordination with the shooting ability using the instep. Recommendations for further research are suggested to involve other independent variables (X) that are relevant to this study, such as leg length, running speed, and angle of impact.

Background: The physical education of students who have a deviation in their state of health requires a joint effort from teachers and doctors. Aim: The aim of the study was to substantiate the necessity of swimming classes as an effective means of physical rehabilitation in students with health disorders within the physical education curriculum classes. Methods: Students with low-level somatic health (54 students) were grouped into the Basic Group (BG, 27 students) and the Control Group (CG, 27 students). The Basic Group students were offered special swimming classes aimed at their physical rehabilitation. At the beginning of the study and after 24 training classes the authors assessed the somatic health, physical and mental endurance, and adaptation abilities of the autonomic nervous system. Results: Implementation of the method into the curriculum of the BG students resulted in a significant improvement (by 48.1%) of their somatic health. A reliable re-distribution of the students with “poor” and “lower than average” somatic health to the “average” and “higher than average” health group was noted (p < 0.05). The students’ physical characteristics improved by 36.4%. Conclusion: The conducted research proved the necessity of using sectional swimming activities as a means of physical rehabilitation of students with low health.

Background: Some of main raisons for the elderly graft occlusion after successful aortal-iliac, aortal Femoral and Femoral Distal Vein Bypass, progression of main disease, continuing bad life Habits and uncontrolled risk factors such are mostly: poor nutrition traditional or fast food, Smocking and Lacks of Walking and Physical Activity Habits. Objective: The primary objective of the study was to estimate influence of Interval Walking Training Program combine with Tribulus Terrestris, 3-5 gram of Taurine and high dose of 1800mg supplementation of ALA on primary potency and vascular treatment. Secondary goals of this study is determinate by establishing better understanding connection between ordinary vascular walking therapy 30-45 min and interval walking program combine with Tribulus Terrestris, Taurine and high dose of and ALA as secondary supplementation after surgical and endovascular treatment. Methodology: The study included 112 patients, at the Clinic of cardiovascular surgery, Clinical Center University of Sarajevo, age between 50 and 75 (50 patients surgical treated with aortic-iliac, aortic-femoral and femoral distal vein bypass with and without Linton-patch/Taylor patch-first group) and (62 endovascular Iliac treated patients (indication TASC II A and B) with and without support Tribulus Terrestris, high dose of ALA and Taurine - second group). Results: Final analysis has reveal the rehabilitation outcome in 83% patients with bypass above the knee was fully rehabilitated compared to 46,6% patients with bypass below the knee was statistically considered significant by using p value less than (p<0,05) In anamnestic history in 83% patient with amputation above the knee was documented the presence of hypertension, hyperlipidemia, nicotinismus and diabetes compared to 66,7% of patients with amputation level below the knee but there was no statistically significant difference (p>0,05). Conclusion: Interval Walking Training Program on Tribulus Terrestris, Taurine and high dose of ALA had a significantly and successfully higher bypass potency and rehabilitation prognosis compare to patients without supplementation and postsurgical physical therapy concept. It is obviously the is certain link between physical activity, life style modification and serum testosterone on primary bypass potency.

This study aimed to investigate the facilitative effect of observational practice combined with mental imagery on learning of soccer dribbling. 140 young boys with the average age of 14,52 (±2,96) and mental imagery score of 48,69 (±5,1), who were unfamiliar with the research task, voluntarily participated in this study. The participants were assigned to homogenous groups according to their pre-tests results as follow: 1- physical practice; 2- observational practice; 3-mental imagery practice; 4-physical-observational practice; 5-physical-mental imagery practice; 6- observational-mental imagery practice and 7- physical-observational-mental imagery practice. Then the participants completed three sessions including ninety trials. At the end of the final training session, an immediate retention test was conducted that followed by a delayed retention test after 48 hours. The results of One-Way ANOVA test indicated that in both immediate and delayed retention tests, the physical-observational-mental imagery group and the physical group had a better performance compared with other groups (p<.05). Furthermore, the combined physical-mental imagery group obtained higher scores in soccer dribbling task in comparison with the combined physical-observational group. The findings support the beneficial effects of cognitive interventions as well as physical practice.

The presented study focuses on the impact analysis of a specific training programme primarily focusing on plyometric exercises for the lower limb explosive power, and the selected parameters of swimming turns. The tested set consisted of performance swimmers (n = 20, men n = 12 and women n = 8) in the average age of 17.3 years, average height of 174.2cm, and average weight of 65.8kg. The tested set was divided into two smaller sets. The experimental set (n = 10) used the training process as an extra experimental factor and the supervision set (n = 10) carried out only the main contents of the training process. The specific training schedule was applied during the period of 8 weeks, three times a week for 20 minutes. The effectiveness of the experimental factor was tested through a selected set of tests, focusing primarily on the lower limb explosive power. Three of the tests were conducted on the dryland using the Myotest machine: T1 – Squat jump (SJ), T2 – Countermovement Jump (CMJ) and T3 – Plyometric jump (PJ). The tests conducted in the swimming pool were: T4 – max. length of floating up after the push off from the turning wall, and T5 – the length of push off after 25m of breaststrokes in the maximum speed with a push off from the wall of maximum floating up. The results pointed out a proportionally higher increase in the experimental set, in which the average percentile improvement of the jump height amounted to 17.7% in T1 (the changes in the supervision set were 0.7%); in T2 the jump height was increased by 22% (the changes in the supervision set were 0.6%); in T3 the time of contact increased by 18.5% (the supervision set showed a decrease by 1.2%), T4 by 14.9% (the changes in the supervision set were 4.1%) and in T5 by 22.7% (the changes in the supervision set were 11.0%). Kendall correlation coefficient (r), pointed out the average value of the correlation coefficient between the experimental factor and the individual tests as follows: T1: r = 0.39, p<0.05; T2: r = 0.41, p<0.05; T3: r = 0.43, p<0.05, T4: r = 0.38, p<0.05 a T5: r = 0.41, p<0.05. In conclusion, practice, improvement, and affectivity of the swimming turn can affect the swimmers’ performance in races and improve it.
