Abstract

The aim of this paper was to determine whether the high-intensity interval training (HIIT) training can improve aerobic fitness in regional-level soccer players. Billat method (30-30s and 15-15s; 6-12 min) was used twice a week for 8 weeks during a season. Twenty-Three National-level soccer team players, (years=25±8, height=183.28±5.93, weight=75.28±5.9), were recruited for this study. Pre- and post-experimental period, maximum oxygen uptake was measured thru pseudo-ramp test on treadmill until volitional fatigue. Obtained results showed improvement in aerobic fitness for post- vs premeasurement (initial measurement = 51.92±3.40, final measurement = 54.87±2.61, p<.001). It is likely that specific high intensity interval training is viable method for aerobic fitness improvements in national-level soccer players when conducted during season.

Abstract

The main purpose of our article was to broaden the knowledge of the level of the motor performance of young soccer players in puberty, taking into account their biological age. The object of our research was 18 soccer players in the U 15 category of the soccer club ŠK Slovan Bratislava divided into a subset with accelerated development (n=10) with body height 177,4 ± 5,1 cm, body weight 65,8 ± 7,5 kg and a subset with retarded development (n=8) with body height 170,9 ± 7,3 cm, body weight 63,9 ± 7,7 kg. To assess the motor performance, a set of 3 tests to evaluate speed and speed-coordination (agility) capabilities was applied. The set of tests contained a 10 m run (n=10 - average value of 1.61 s, n=8 - average value of 1.62 s), a 30 m run (n=10 - average value of 4.13 s, n=8 - average value of 4.16 s) and a 5 x 10 m run with a change of direction (n=10 - average value of 11.55 s, n=8 - average value of 11.70 s). Using the Mann-Whitney U test, we did not confirm in our case a statistically significant different level in the motor performance of the monitored sets with regard to the degree of their biological maturity.

Abstract

The aim of this study was to establish the gender-related differences among children 6-6.5 years of age in anthropometric characteristics so as to observe their development and make more appropriate selection for participation in guided and organised physical activities. A battery of 7 anthropometric measurements was used on the representative sample of 175 subjects of both genders from Valjevo (M=45 aged 6 and M=83 aged 6.5; F = 44 aged 6 and F=43 aged 6.5). The multivariate analysis of variance showed the existence of statistically significant differences (p=0.00) in the anthropometric space of the two ages analysed regarding the gender. Through the individual analysis, the differences at age 6 were found in the Upper arm skin fold variable (p=0.03) and the Back skin fold (p=0.00), whereas with the 6.5-year-old subjects, the differences were found in the Body height variable (p=0.03), Upper arm skin fold (p=0.00) and Back skin fold (p=0.02), both in favour of the boys. It can be assumed that the differences are the result of the endogenous and exogenous factors upon the children's organism in the period of childhood in a smaller urban community of the southwest Serbia.

Abstract

Abstract The aim of this study is to establish the effects of specially programmed circuit training on physical fitness in primary school children. A total of 58 (28 girls) primary school children aged 11-13 (experimental group 12.2±1.2, control group 12.4±1.1) years voluntarily participated in this study. Physical fitness of children is assessed based on motor skills, through the following tests: abdominal muscle endurance - Sit-ups test, upper body strength and muscular endurance - Bent-arm hang test, upper-body muscular endurance - Push-ups test, muscular strength and power of the lower limbs - Standing broad jump test, agility and speed - 4x10m test and flexibility - Sit and reach test. During the regular classes of physical education, the experimental group conducted a circular training lasting 15-20 minutes, at the same time control group practiced exercises that were in accordance with the plan and program of teaching physical education for a particular teaching unit. The treatment lasted for 15 weeks, with two classes of physical education per week. The results for the standing broad jump indicated significant differences between groups following 15 weeks. Furthermore, the group that participated in the circuit training program made significantly greater gains compared to the control group (p<0.05) in bent-arm hang, sit-ups and sit and reach. The results for the 4x10m test indicated no significant differences in time, group and their interaction (p≥0.05). To conclude, circuit training appears to be an effective way of improving physical fitness in primary school children. The results of this study indicate that this method was more effective for performance than traditional school programme.

Abstract

The aim of this research was to examine differences in the use of self-handicapping strategies in athletes and non-athletes, changes in self-handicapping strategies that can occur with the approach of an important event, and the relationships between these strategies and personality traits, gender, and some external criteria such as performance. The sample included 183 subjects (mean age 21.16 years) consisting of 102 non-athletes and 81 athletes. Three questionnaires were used: VP+2, for measuring personality dimensions of seven-factor model, SH-17, for the assessment of changes in the use of self-handicapping strategies through time and a general biographical questionnaire. A general linear model for repeated measures was used for data analysis. Significant correlation was found between self-handicapping strategies and the number of medals and awards won at international and domestic competitions. The results also showed a positive correlation between self-handicapping strategies and dimensions of Neuroticism and Extraversion and negative with Conscientiousness. Also, a statistically significant difference in the use of self-handicapping strategies was found between athletes and non-athletes, showing that non-athletes express more self-handicapping behaviour. The results indicate that the frequency of self-handicapping behaviour does not change through time. The effect of gender on self-handicapping is not significant, but there was a statistically significant interaction effect of gender and population on self-handicapping behaviour. It indicates that male non-athletes are more prone to self-handicapping 10 days before an important competition (exam or public speaking for general population, or “game of the season” for sporting population) compared to male athletes. These results, apart from the gender differences, are consistent with the results of previous studies. Limitations of this research and possible directions for future studies were also considered.

Abstract

Studies concerning the effects of different invasion games on physical fitness in school children are scarce. Consequently, the purpose of this study was to examine the effects of the application of invasion games on physical fitness in primary school children. A total of 62 primary school children aged 10-12 years voluntarily participated in this study. They were divided into experimental (32) and control (30) group. Physical fitness of children was estimated by the following tests: Standing broad jump, Vertical jump, Bent-arm hang, Sit-ups, Push- ups, Medicine ball test and Andersen test. The experimental group had twice per week invasion games on non-consecutive days for 12 weeks. Participants in control group did not perform specific program but attended their regular PE class twice per week. Compared with initial measurement, there was a significant (p < 0.05) improvement in vertical jump test for both groups. Furthermore, the group that participated in the invasion games program made significantly greater gains compared to the control group (p < 0.05) in Standing broad jump (8.2%; ES=0.56 vs. 3%; ES=0.2) and Medicine ball test (8.2%; ES=0.6 vs. 3%; ES=0.3). There was a significant improvement in bent arm hang, sit ups and push-ups in experimental group. Compared with initial measurement, there was a significant (p < 0.05) improvement in Andersen test in invasion games group, which was not the case with control group (p>0.05). To conclude, invasion games were an effective way of improving physical fitness in primary school children, because the results of this study indicate that this method was more effective for physical fitness than traditional school program.

Abstract

Measuring of morphological characteristics and motor abilities was performed on the sample of 51 male students of the secondary traffic school “Pinki” from Novi Sad. Body height and body mass were used for measuring of morphological characteristics, and results of standing long jump and running at 30 meters with standing start were used for measuring of motor abilities. The body mass index was calculated after the results were obtained. The aims of the study were to establish and analyze differences in the results of morphological status and explosive strength of students measured in different periods, in the first measurement when the subjects were 15 years old and in the second measurement when the subjects were 17 years old. The data obtained in the study were analyzed using repeated measures ANOVA. The obtained results indicate the existence of statistically significant differences between first and second measurement in all morphological characteristics and motor abilities, at the level of significance of p<0.05.A significant increase in morphological characteristics and motor abilities with age, indicating that boys have adequate growth and development for their age.The age factor has a significantly stronger influence than the factor of the curriculum for the physical education in this high school.

Abstract

Fencing is very dynamic and combative sport, with the following requirements of competitors: instant resourcefulness, precision, courage and fast reaction in different situations. It is just for this reason that the training of young fencers involves improvement of all motor abilities focusing on agility, speed, and explosive strength. The aim of this research is to determine gender-related differences of motor abilities in children engaged in fencing. The sample consists of 50 children (26 boys and 24 girls) whose average age is 10.46 years and, who train fencing in the “Omladinac” in Zrenjanin and “Vojvodina” in Novi Sad. Motor abilities are tested by means of four motor tests. Differences are determined using multivariate analysis of variance and univariate analysis of variance. The findings indicate that there is statistically significant difference related to Deep forward bend on the bench and T-test, which is in favor of girls, Long jump test from the standing start in favor of boys, whereas Tapping test does not show any significant difference between boys and girls. Numerous research works show that early early maturing girls have better results of motor performance than those with a slower process of maturation (11-13 years), whereas individual differences in terms of motor performance depend on growth and development, especially in boys. Matching of results is related to the observed statistically significant differences in explosive strength in favor of boys and suppleness in favor of girls.

Abstract

The objective of this study represents the sports branding, while the main goal will be directional to explaining the contemporary sports product and making a brand. The main tasks of this study are, the first discussing the sports branding nowadays and newly created sports products as well as drawing attention to the specific nature of the branding of sports products as a separate field of branding in general. During making of this study, the authors used descriptive method with consulting of competent literature. The previous authors’ experience in this field was also so useful. Moreover, the author used the analytic method and parallel method that is the most productive if you make some inferences about some appearance. From the reason sport branding did not develop separately, it is the fact that it represents an integral part of the overall branding procedure; however, sport branding has some specialty in relation to other areas, mostly due to the reason, sport industry has much more unpredictable nature than most of other industries. This study made general retrospection of common characteristics and differences among sports branding and branding in general that might be relevant for many researchers in this area. Sports branding is developing rapidly around the world, the dominant example of this development is most evident in the “sports industry” in the United States. However, the sport branding is not at the expectable level in Montenegro, and working on recognizing Montenegrin contemporary sports product and making a brand must be more prominent nowadays.

Abstract

Pregnancy is a physiological condition during which a series of morphological and anatomical changes occur. Adaptation to new changes in the body depends on the psychological and physical condition of the patient. One of the many factors that affect the quality of life is physical exercise. Proper exercise prevents certain chronic diseases, reduces pregnancy discomfort, gives a feeling of satisfaction and influences a positive outcome of the pregnancy. The aim of this study was to examine the validity of the preliminary version of the questionnaire, and therefore examine the impact of exercise on the quality of life during pregnancy. The questionnaire involved pregnant women (N=33). All of whom were in their third trimester of pregnancy. The participants voluntarily filled out an anonymous questionnaire. The questionnaire included information about: social and marital status, education, frequency of maternity problems, the type of exercise, as well as the level of training load during pregnancy. High reliability and validity of the survey (0,873) was determined by Cronbach alpha coefficient. Pregnant women (48%) commonly practiced low intensity yoga, up to three times a week. Most of the women (45%) believe that the exercise has a positive impact on their health. A difference of statistical significance was observed between the type of exercise and heart burn (r=0.349; p=0.046), as well as between the type of exercise and body weight (r=0.357; p=0.041). The results of this pilot study show a lower incidence of common maternity symptoms in pregnant women who exercised during pregnancy.

Abstract

The goal of this study was to examine the influence of dancing and game contents on preschoolers’ motor engagement in each phase, as well as total engagement in directed motor activities. The study was realized in the first term of 2014/2015 school year. 12 activities with dancing contents and 12 activities with moving games were monitored. The duration of directed motor activity phases was as follows: the first A phase (introductory) – five minutes, the first B phase (preparatory) – five minutes, the second phase (main) – fifteen minutes and the third phase (final) – five minutes. The time of the activity (engagement) was measured by random choice of one of the children, who was monitored during the directed activity. The observed child did not know that he/she was an object of measurement. Data processing included descriptive statistics and t-test for small independent samples. The parameters of descriptive statistics indicate longer engagement of children in the first A phase, the third phase and total engagement with dancing contents. Game contents influenced higher engagement in the first B phase and the second phase. Game contents influenced statistically significant difference in relation to dancing contents in the third phase. The total engagement with the dancing contents was 725 seconds, with game contents 707 seconds. The t-test does not indicate statistically significant difference between dancing and game contents in terms of preschoolers' total engagement. The results indicate that the activities with dancing and game contents are very useful in working with preschoolers.

Abstract

The subject of this study are metric characteristics of specific football tests. 27 football players chronorogical age of 13-15 years, apropos categories of elder pioneers from HNK Cibalia Vinkovci, Croatia. The participants had to go through specific tests with the ball: 20 m sprint, zig-zag, slalom, and 9-3-6-3-9 test. We can conclude that all four variables are highly reliable. The homogeneity of the measuring instrument is good (20 ml) and excellent( zig-zag L, slalom L, 93639 L), and results of skewness and kurtosis further show good sensibility of the measuring instrument, with the exception 20 m L2 variable, which is positive asymmetrically distributed and elongated. The correlation of particles with first main component, which is second condition for homogeneity of the measuring instrument, points on high homogeneity of all tests. Regular distribution of all test implies on satisfactory reception of all four tests for assessing the speed and agility. The factor analysis has given one significant component and the amount of explanied variance and size of characteristic valuables are high, so we could confirm also factorial validitiy of tests. The results of the variance analysis (ANOVA) conclude that the tests are pragmatically valid, and they distinguish players from different playing lines.

Abstract

Skill-based training has been developed in order to combine the skill and conditioning elements in a coordinated approach. Our aim was to determine the effects of skill based conditioning training on power and COD speed in youth female volleyball players. Sixteen young female volleyball athletes (15±2 years) consented to participate in lower-body power and COD speed testing.Players were involved in six weeks skill-based conditioning training during in-season. There were no significant differences between pretraining and posttraining for Block jump and Spike jump. Moreover, there were no significant (p > 0.05) improvements in Standing broad jump also.However, compared with pretraining, there was a significant improvement in COD speed tests. Training induced significant (p ≤ 0.05) improvements in 9-3-6-3-9 test (p<0,001) and Side steps 10x4.5 m (p<0,001).In conclusion, skill-based conditioning training appears to have stronger effects in improving COD speed compared to lover body power young female volleyball players. Volleyball coaches could use this information in the process of planning the in-season training.

Abstract

This study presents the results of empirical research conducted with the aim of analyzing differences in the physical activity of children in relation to the socio-economic characteristics of their families. The research was conducted by applying a questionnaire distributed to pupils aged 11-12 years, who live in the city of Novi Sad (the city and the village of Rumenka, Veternik, Kac, Bukovac, Futog). Bearing in mind that the work is a part of a broader research, the authors' attention was focused on the objective, and the evaluation of the respondents on the socioeconomic status of the family, as well as differences in physical activity among boys and girls, and children who live in urban or rural setting. As dominant in this study stands out the finding of the author that the socioeconomic characteristics of families significantly affect the intensity, form and quality of physical activity of children. Since such a finding puts children living in families with low socioeconomic status into a disadvantaged position, the authors believe that with the findings of this and compatible researches it is needed to familiarize with the wider academic community, in order to include other social institutions in the process of affirmation of physical activity as an important lifestyle quality in children and youth.

Abstract

Since previous studies suggest a relationship between motor and cognitive development in children, a research was conducted in order to examine the differences in motor skills of children with different levels of intellectual ability. In a sample of 88 respondents, boys and girls aged 7, an assessment of motor skills was performed by using the battery of seven motor tests and assessment of intellectual abilities by using the test of Raven's Coloured Progressive Matrices. Respondents were divided into three groups according to the results of the test. After analyzing the results of the research it was shown that there were no statistically significant differences in the area of motor abilities of children of different intellectual levels, but there were differences at the univariate level regarding the tests Hand Tapping and Seat-and-Reach.
