Thirty-six female basketball players were recruited from three professional State Basketball league of Bosnia and Herzegovina clubs (age: 18.81 ± 2.58 years) who completed three separate trials of the RTADST with each trial consisting of fast shuffling movements left and right. Each athlete performed the test 3 times in one day, and repeated testing was conducted the following day at evening basketball sessions. The RTADST relative reliability was evaluated by Cronbach’s alpha and ICC. Cronbach’s alpha coefficient was 0.81 which indicates good reliability. When recommendations from Bucheit et al. (2011) were taken into account, the value of ICC <0.69 indicated poor reliability. Absolute reliability of RTADST was assessed by CV, and its value was 5.3%, which is somewhat above the 5%, or the limit of acceptable reliability. Parame...

Forty-four boys took part in this study: 20 basketball players (average age 14.4 ±.31) and 24 handball players (average age 14.5 ±.41). In order to assess the morphological status of athletes we applied four, and for motor status assessment, 10 variables. Yo-Yo test was used to estimate athletes’ functional status. By arithmetic means, we presented a model of the desirable physical performances of basketball and handball players. The t-test for independent samples was used to determine the significance of differences between the two groups of athletes. Basketball players had better results in all 15 tests, although the difference is statistically significant in 11 tests. The difference in quality was explained by a fact that basketball is three times popular among children compare to handball, and lack of sports halls in Bosnia and Herzegovina ...

The game-related statistics that were analyzed are 2- and 3-point field-goals (both successful and unsuccessful), free-throws (both successful and unsuccessful), defensive and offensive rebounds, assists, turnovers, steals, blocks made, blocks received, fouls committed and fouls received. Results of the discriminant analysis showed that winning teams differ from losing teams in assists (SC=0.417), defensive rebounds (SC=0.399) and in successful 2-point (SC=0.355) and 3-point field goals (SC=0.325). In balanced games winning differ from losing teams in defensive rebounds (SC=0.388), successful 2-point field goals (SC=0.343) and blocks ...

A total of 398 primary school students from the urban and rural environment, aged 12 to 14, were tested for motor and cognitive abilities. The influence of relevant socio-demographic factors was examined by means of a multiple hierarchical regression analysis. Two socio-demographic variables had a significant influence on the motor and cognitive abilities: residential status and father's education. Urban students revealed better results in motor (except for rural girls) and cognitive ability tests. Father's education level was the second factor exerting an additional impact on these abilities, showing higher values for the urban environment students.

This variation in birth dates among children grouped in the same generation is known as relative age and its implications on different developmental outcomes are referred to as relative age effects (RAEs). The previous body of research of RAEs in youth populations has focused on sporting samples; however, studies examining RAEs in physical education are scarce. The current study investigates the influence of the RAEs on motor abilities in a sample of adolescent pupils. The results indicate significant differences in motor abilities between relatively older and relatively younger participants of both sexes. Since RAE is an under-researched area in physical education, the results may have substantial implications for PE assessment given the fact that many PE teachers still carry out typical norm-referenced assessments. Possible recommendations for future res...

Thirty-four volunteers (mean ± SD; age 15.74 ± 1.23 years, height 187.61 ± 7.95 cm, body mass 74.09± 11.61 kg; training experience 6.30± 2.15 years) participated in the study. The 20-m shuttle run test was performed wearing a portable gas analyzer (K4b2, Cosmed) to measure VO2max during the test. SRT-derived VO2max underestimated directly measured values (48.91 ± 4,11 vs 55.45 ± 4.98). Mean bias was 6.54± 3.89 ml kg min (95% CI5.18 to 7.90 ml kg min ). Typical error of the estimate was 3.85 ml/kg/min (95% CI3.10 to 5.10 ml kg min ; ES= 0,77). There was a moderate correlation between VO2max directly measured and estimated by SRT (r= 0.65; 95% CI0.40 to 0.81, power = 0.84, p < 0.01). Although very popular among coaches, it seems that SRT is not an appropriate field test to measure maximal oxyg...

Material and methods: The sample consisted of 60 junior and senior basketball players from the youth league of Bosnia and Herzegovina (B&H), and the national level – the First Division of B&H. The authors found that some players during a game and training sessions apply an SMDS of the shooting arm as a pre-shot routine for FTP. Since previous literature suggests that length of the routine and pre-performance behaviors are quite different among players of all levels, the sample was divided based on the number of training hours per week (lower/higher number of training hours) and basketball experience (experienced/less experienced). The procedure involves every player performing five free throws (FTs) without prior stretching, five FTs immediately after SMDS of the triceps muscle and five FTs after SMD...

The aim of this study was to define physical profile of 14 year old football and basketball players, based on discovered differences in morphological, motor and functional domain. The sample was consisted of 40 boys, aged 14. Morphological variables: body height, body mass, body mass index, body fat percent, arm span and chest circumference. Motor variables: 10 m sprint, zig-zag test, polygon backwards, squat jump, shoulder fl exibility and push-ups. Functional test: Yo-Yo intermittent endurance test level 2. Th e following apparatuses were used: body composition analyzer (TANITA BC 418-MA III), photo cells (Globus ergo System), jumping fi eld platform (Globus ergo systeм), centimeter tape, mattresses and audio signal machine. The results showed significant differences between football and basketball players in variables body h...

The aim of study was to establish differences in the conformity degree between groups of athletes, categorized under 3 criteria: type of sports, gender and athletes’ competition experience. Sample of participants was consisted of 160 athletes. The research instrument was conformity scale (The Conformity Scale, Mehrabian, & Stefl, 1995), used and confirmed in 2 earlier researches of Vučković et al. (2009, 2010). Data were analysed by non-parametric Mann-Whitney test. Upon analysis, it’s been confirmed that: a) athletes are bigger conformists toward coach than club management, b) team sport athletes are bigger conformists toward coach, c) there no differences between male and female athletes in conformity toward coach and club management, d) there is no statistically significant differences between experienced and less experienced athletes in their conformity degree towa...

Teorijsko-empirijsko istraživanje sprovedeno je na uzorku od 188 učenica (urbana sredina = 98 učenica; ruralna sredina = 90 učenica) šestog i sedmog razreda osnovne škole. Rezultati kanoničke diskriminativne analize motoričkih sposobnosti učenica pokazali su da postoje značajne razlike u motoričkim sposobnostima ispitanica različitog rezidencijalnog statusa. Devojčice iz ruralne sredine imale su bolje rezultate u većini testova (10 od 18), ali ta većina nije apsolutna. Na osnovu dobijenih rezultata može se pretpostaviti da upravo sredinski faktori različitih životnih sredina doprinose razlici u motoričkim sposobnostima ispitanica.

On the other hand, considering differences of motor skills abilities between genders, it has been confirmed in a number of studies that boys had better results than girls. Results of this study, conducted on sample of 150 boys and girls from seventh grade of primary school, are very consistent to those findings, with small differences. Namely, girls had better results in five tests: two flexibility tests (shoulder flexibility–SF and forward bend on the bench–FBB), speed test (foot tapping-FT), one coordination test (arm and leg drumming - ALD) and one balance tests (standing on the reversed balance rail - SRR), which indicates somewhat smaller differences in motor abilities between boys and girls for tested sample. Key words: boys, girls, motor skills, primary school
