Research was conducted on sample subject of 130 female volleyball players aged from 13±0.6 (mean±SD). Sample variables are divided in two groups: 9 variables of assessment of basic motor skills and 5 variables of assessment of situational motor skills. Analysing difference of arithmetic means between of initial and final measures of treated variables it is determined that there is statistically significant difference on the level Sig=0.001, except for variables of Jelka test which determinates speed duration of female volleyball players. Analysis of quantity changes of basic motor skills, shows that the most important projections on selected discriminative function of basic motor skills have the following variables: body lifting in 30 sec; dynamometry of a hand, hand tapping; pull-up; throwing a 1 kg ball from lying ...

Program was design to increase power and strength of knee extensors and flexors using neuromuscular adaptation. In overall, 18 senior level football players completed intervention in preparation period executing program as part of warm up 2-3 times per week. Using t-test for dependent samples statistical significance of the possible change was evaluated in peak torque, total and average work changes measured using Biodex isokinetic dynamometer. All measuring procedures were done for both limbs. Results are suggesting that statistically significant change observed in both limbs for the peak power output and average work load in flexion and extension, respectively. Other research papers are suggesting that increase of power and strength of knee muscles can help in preventing of injurie occurrence. LCA injurie can be prevention when femoral biceps st...

This research represents a transversal study with a goal to determine level of differences between two main components (left and right leg) of locomotory system of basketball players by measuring their morphological characteristics and motor abilities. The subject sample consisted of cadet basketball players from Sarajevo Canton as well as cadet national team of Bosnia and Herzegovina (N=68). For morphological measurements, four variables that explained voluminosity and longitudinal measures for both leg were applied. Motor abilities were presented through fifteen variables on Biodex isokinetic system and Biodex balance system. With overall fourteen variables, information regarding knee stab...

Spleen contracts during the exercise and so augment the systemic circulation and helps body to maintain longer on high intensity exercise. Reviewing all available literature, the human spleen shows a decrease in volume, in range from 8% to 56%, depending on the work intensity. Aim: To evaluate the percentage of the decrease in splenic volume after the treadmill exercise at specific workloads: aerobic threshold intensity, anaerobic threshold intensity, submaximal intensity and maximal intensity. Methods: This prospective study with repeated measurements included 16 healthy subjects, divided in two groups. First group consisted of 8 elite long-distance runners and second group of 8 recreational runners. First testing consisted of treadmill ergospirometry test. This data was crucial for the second testing where subjects were exercising on treadmill at specific workloads. Four specific workloads were determined: treadmill exercise at aerobic threshold intensity (1st workload), anaerobic threshold intensity (2nd workload), submaximal intensity (3rd workload) and maximal intensity (4th workload). Workloads were controlled by the speed of treadmill, for each subject individually regarding the ergospirometry test. Ultrasound measurement of spleen was done before and after each workload. Results: Elite long-distance runners showed greater spleen contraction than recreational runners after four workloads. Spleen contraction was the biggest after the 3rd workload in elite long-distance runners. Smallest contraction was in group of recreational runners after the 1st workload. Statistically significant difference was not found between the groups, regarding the splenic volume after exercise at four specific workloads (p>0.05). Conclusion: Elite long-distance runners had greater decrease in splenic volume than recreational runners, after exercise at four specific workloads, without significant difference. Greatest decrease happened in elite long-distance runners, after exercise at submaximal intensity-49% decrease in splenic volume.

However, the effectiveness of these programs is poorly described when co-administered along with conventional pharmacological therapy. PURPOSE: To compare responses in selected hemodynamic outcomes among patient suffering from peripheral artery diseases of lower limbs assigned to medication therapy (MT), and medication therapy and prescribed exercise (MTPE). METHODS: Sixty-four male patients participated in this study, with participants separated into MT group (n=33) and MTPE group (n=31). Exercise program included 3-5 sessions per week lasting for 30 to 50 min, during 4-month period. The claudication distance and peak systolic velocity (PSV) were measured for both groups at beginning and at the end of the study. RESULTS: At follow up, both PSV and claudication distance improved in MT and MTPE as compared to the baseline (p < 0.05), with the degree of improvement or claudication distance was higher in MTPE group (97.5 vs 61.72%; p < 0.01). CONCLUSION: Prescribed exercise program improved clinician-reported outcomes in men with peripheral artery disease when co-administered with pharmacological therapy.

It’s obvious that their motoric develops relatively slowly and it is accompanied by significantly reduced moving abilities (Jobling, 1994; Ulrich, 1992). The aim of this research was to establish the level of changes of motoric status under the impact of programme activities of water games and exercises of children with DS. METHODS The research has been conducted with the sample comprising of 12 children with DS, 8 male (n=8, mean age=9.7±3. yrs; mean height= 1.32±0.16m, mean weight= 41.9±15.5 kg) as well as 4 female examinees (n=4, mean age=9.1±3.6 yrs; mean height=1.29±0.13m; mean weight= 30.5±7.5 kg). The programme was carried out within the period of 12 weeks at the pool for non-swimmers training (average water temperature 28,6 C), twice a week per 60 minutes. Both prior and after the carried out programme, a testing of a part o...

After registering cognitive event related potentials at rest participants underwent a controlled exercise on a cycle ergometer. Each exercise lasted for 10 minutes with succesive increase of intensity up to 60%, 75% and 90% of maximal heart rate. Immediately after finishing each bout of exercise, event related potentials were registered again. The results of our study implicate that acute bouts of exercise at different intensities make an impact on cognitive functions of female judo players compared with the group of healthy female students. In our study the effects of single bouts of exercise at different intensities seem to be positive on the amplitude of P300 componennt of ERP. Short duration medium intensity exercise corresponding to 60% and 75% HRmax facilitated co...

Such changes we recognize as: a) quantitative changes (linear move without changes in relations), b) structural changes (changes of relations of manifest or latent dimensions), c) taxons restructuring (changes of entity positions as allocations), and d) individual changes (local specific individual adaptations on applied stimuli systems). Totally different changes we can determine under the model offered in this article. Usually, we suppose that the field of events in several time points is the same, just because we have surround that field with the same variables for all time points. However, we forget that field event in the "second", "third" (…) time point is no longer the same field as in the "first", simply since everything is changed exactly because the field structure is directly influence...
