Hammer throw is motor-wise an extremely complex throwing discipline with the manifestation of several different forces that impede the rotational movement of the device and the thrower in the projected sagittal plane. Kinematic parameters are one of the segments when analyzing athletic disciplines, including hammer throw. This study aims to determine spatial and time differences of kinematic parameters between male and female hammer throw finalists at the 2017 Athletics World Cup in London. The study was conducted on a sample of 24 finalists of the 2017 Athletics World Cup in London, with the aim to analyze the differences in kinematic parameters between male and female hammer throwers. The results were acquired by applying the Independent Sample t-Test. It has confirmed the differences in most of the parameters, except those regarding ejection height (T=2,992; p<0,009), where it established statistically significant discrepancies between male and female finalists. On average, the male finalists threw a hammer from a height of 1,74±0,13m, and the female finalists from 1,54±0,17m. Based on the obtained results of kinematic parameters, it can be concluded that quantitative and qualitative differences in the measured kinematic parameters of the finalists in London are evident, but that statistically significant differences are recorded only in the ejection hight of the device.

Bacanje kladiva je motorički vrlo kompleksna bacačka disciplina sa manifestacijom više različitih sila koje nastoje da onemoguće rotaciono kretanje sprave i bacača u projektovanoj sagtalnoj ravni. Kinematički parametri su jedan od segmenata u analizi atletskih disciplina, uključujući i bacanje kladiva. Cilj studije bio je da se utvrde prostorne i vremenske razlike kinematičkih parametara između muških i ženskih finalista, bacača kladiva Svjetskog prvenstva u Londonu. Studija je sprovedena na uzorku 24 finalista Svjetskog prvenstva u Londonu, 2017, sa ciljem analize razlika kinematičkih parametara između muških i ženskih bacača kladiva. Da bi se dobili potrebni rezultati primenjen je t-test za male nezavisne uzorke. Rezultati su potvrdili razlike u većini mjerenih parametara ali statistički značajne razlike između muških i ženskih finalista su potvrđene samo u visini izbačaja (T=2,992; p<0,009). Muški finalisti su bacali kladivo u prosjeku sa visine 1,74±0,13m, a žene sa 1,54±0,17m. Na osnovu dobijenih rezultata kinematičkih parametara može se zaključiti da su evidentne kvantitativne i kvalitativne razlike u mjerenim kinematičkim parametrima finalista u Londonu, ali da su statistički značajne razlike evidentrane samo u visini izbačaja sprave.

Istraživanje je provedeno sa ciljem procjenjivanja efekata programa aerobnih vježbi na tjelesni sastav žena sa prekomjernom tjelesnom težinom u dobi od 22 do 27 godina. Uzorak od 30 žena sa prekomjernom težinom u dobi od 22 do 27 godina iz okruga Tonsa (Pandžab), Pakistan bio je uključen u istraživanje. Program vježbanja od četiri sedmice pripremljen je i proveden sa ispitanicama eksperimentalne grupe. Eksperimentalna grupa je podvrgnuta mjerenju antropometrijskih, kao i mjerenja kožnih nabora (3 nabora). Podaci izmjereni prije i poslije programa (kod kontrolne i eksperimentalne grupe) su pažljivo zabilježeni kao baza podataka. Za dobijanje valjanih zaključaka korištene su deskriptivna (srednja i standardna devijacija) i inferencijalna statistika (nezavisni uzorak t-test i upareni uzorak t-test).Analizom podataka utvrđeno je da je srednja ocjena (EG) prije i poslije programa iznosila 28,66 i 23,5. T-vrijednost tabele je 5,022, a statistička značajnost 0,001 - što je niže od nivoa značajnosti (P <0,05), pa se zaključuje da je razlika između prije i poslije pokazala značajne efekte aerobnih vježbi na postotak tjelesne masti kod ispitanica kontrolne grupe. Prema analiziranim podacima, srednja vrijednost post-testova u pogledu postotka tjelesne masti kontrolne grupe iznosila je 28,89, a eksperimentalne grupe 23,5. Statistička značajnost 0,002 i vrijednost t -987 u tabeli prikazuju značajnu statističku razliku indeksa tjelesne mase (P <0,05) kod ispitanica kontrolne i eksperimentalne grupe. Dobijeni rezultati su ukazali na to da su aerobne aktivnosti tokom četiri sedmice vježbanja imale značajan efekat na ispitanice sa prekomjernom težinom u smislu smanjenja postotka njihove tjelesne masti. Na osnovu dobjenih rezultata, preporučuje se da se žene sve više uključuju u fizičke aktivnosti i vježbanje.

concept and and/or assembly of data; data analysis and interpretation; Research on moderate-intensity continuous training (MICT) is closely connected with primary and secondary cardiovascular protection but also can be associated with primary bypass patency and outcome of endovascular treatment for critical iliac stenosis TASC II A and B. After specific surgical or non-surgical treatment, iliac bypass or endovascular revascularization patency still depends on an individual and is still in the eye of scientific research modalities. Carotid intima-media thickness (CIMT) is an efficient surrogate parameter in detection and prediction of cerebrovascular events and potential marker of generalized atherosclerosis with prognosis of peripheral arterial disease related to prognosis of atherosclerotic coronary hemodynamic pathology. Materials and methods. A total of 139 patients were observed during 4 years of MICT. Ultrasonography of the distal part of the common carotid artery (CCA) was performed to measure CIMT before and after revascularization procedure. The bypass patency and walking distance was also studied. Results. In the total population, no difference in changes of CIMT from baseline was observed between the standard exercise group and controls in 4 years. However, there was a significant correlation between the effect of exercise training and CIMT within 4 years. CIMT was not significantly reduced in the exercise group compared with control non-diabetic patients. Conclusions. Exercise training in both groups did not significantly change carotid intima-media thickness in the four years following endovascular procedure and Dacron bypass revascularization, but significant beneficial effect of moderate-intensity continuous training on bypass patency was observed in patients with mild or without claudication symptoms as well as on subjective and objective health status.

Background: The Worlds Athletics Championships, along with the Olympic Games, represent the largest review of athletes in which they record top results, often projecting new world records. Any research that analyzes top athletes contributes to shedding light on a number of issues. It is especially interesting to analyze and compare the results of athletes from one time distance. The main goal of the research was to determine the result differences in sprint, jumping and throwing disciplines, between men's and women's finalists participating in the World Athletics Championships in Edmonton, 2001 and Doha in 2019. Methods: the current study included a total of 493 finalists (247 men's and 246 women's) of the World Championships in Edmonton, 2001 and Doha, 2019. The results in sprint, jumping and throwing disciplines were analyzed in order to determine the result differences in the championship finals. To obtain the necessary information, a t-test for independent samples was applied and the relevant statistical parameters were calculated. Results: the results were confirmed between the final evident differences in all disciplines. Men in Edmonton were successful in 41% of the discipline (400m, pole vault, discus throw, hammer throw, javelin throw), and in Doha 59% of the discipline (100m, 200m, 110H, high jump, long jump, triple jump), while in the category of women's finalists, participants in Edmonton were successful in 17% of disciplines (long jump, throwing the ball), while female athletes were successful in 83% of disciplines (100m, 200m, 400m, 110H, triple jump, high jump, high jump with a pole, Throwing a spear, throwing a discus, throwing a hammer). Statistically significant differences between male finalists were recorded only in the disciplines: 200m (t=2.318; p, throwing the ball (t= -2.939; p and hammer throw (t= -2.802; p, and in female finalists in the 200m disciplines (t=2.402; p, pole vault (t=-5.552; p and hammer throw (t= -6.410; p Conclusion: the consequences of this distribution of differences finalist can be found in various morphological, motor and biomechanical parameters, technical experience, neuromuscular movements, level of motivation and preparedness at the time of onset and other endogenous-exogenous factors.

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.
