Physical activity is important for the physical and mental health of almost everyone. Nordic walking is a physical activity in which participants use specially designed poles while walking, while the term jogging implies light running at speeds less than 10 km/h. PURPOSE: The aim of this research is to monitor the load intensity in real conditions, using a heart rate monitor Team Polar System, during nordic walking and jogging and comparing possible differences in heart rate responses after the fifth minute of activity, at an average speed of 7.5km/h. METHODS: The assessment of heart rate responses for this research was conducted on the 30 male students, at 2 separate days. RESULTS: The results of the variables used in this study show statistically significant differences at the level of significance p=.000. From the mean value results (M) it is obvious that the respondents achieved higher results of heart rate responses during nordic walking compared to the identical tests applied during jogging. CONCLUSION: The results of this study indicate that both Nordic walking and jogging are beneficial but Nordic walking contributes more in achieving higher body loads resulting in increased oxygen consumption and thus calories Key words: load intensity, heart rate, nordic walking, jogging

Background: The novel coronavirus disease 2019 (COVID-19) seems to be having a significant impact on physical activity behaviors globally. The pandemic has forced many of us around the world to remain reception and self-isolate for a period of your time. Aims and Objectives: The aim of this paper was to find out how much the measures due to the COVID-19 pandemic affected the daily lives and how the measures affect the physical activity and mental health of students after 81 days. Materials and methods: A total of 67 participants have answered the questionnaire. The participants were 48 (71.6%) males and 19 (28.4%) females. The mean age of all participants 22.28 years. Study Design and Setting: The questionnaire is divided into several different chapters: personal characteristics, sleep habits, level of physical activity, social functioning and viewing habits, general health condition, COVID-19. Statistics: Statistical differences between male and female students were tested using the chi-square test and t-test. A p-value of < 0.05 was considered statistically significant. Results: Inactivity had a more negative effect on the male population than on women. In this article, the author will highlight the potential impact of the COVID-19 outbreak on the physical activity and mental health of students. The data showed that the COVID-19 pandemic lockdown affected the academic performance of most participants. Conclusion: Home-based activities provide an opportunity for students to stay fit and healthy by practising simple movements while staying at home without the usual student obligations. We see that student confinement did not affect both sexes the same.

The aim of this research was to determine the effects of experimental short-term program of intensive training of alpine skiing techniques (experimental program) on morphological characteristics (body composition) of students. The sample is divided into an experimental group (31 males, age 21.4 ± 1 and body height 180.7 ± 6.3cm) beginners who were on skis for the first time and control group (34 males, age 20.6 ± .8 and body height 180.3 ± 6.8 cm). The following body parameters were measured at the beginning and end of the experimental program: body weight, body mass index, fat percent, total weight (in kg) of fat in the body, total weight (in kg) of body mass without body fat, total weight (in kg) of water in the body. To determine the effects of an experimental program on some morphological characteristics of students a univariate covariance analysis was applied. Results of ANCOVA show statistically significant effects of the applied experimental program in variable total weight (in kg) of water in the body p = .018 where the variable showed higher values for the experimental group compared to the control group.

Morphol., 33(1):158-163, 2015.SUMMARY: The main objective of this study was to obtain information on indicators of obesity among the unemployed malesubjects from the Tuzla Canton. Also, we wanted to determine whether there are significant differences in the observed parametersbetween subjects in relation to age. The main criterion for the selection of test subjects is that they are unemployed. This is because wefelt that those persons have more free time for practicing sports and recreational activities, and there is a very small number of studies inthe area of Tuzla Canton with the characteristics of the sample. For the purpose of this research we applied analysis of percen tage/ratio,t-test for independent samples and the Mann-Whitney U Test. Applied analysis showed that the increased value of Body Mass Index(BMI) and to the account of increased amounts of body fat has 31.5% of the respondents. It also found that there are significantdifferences in the variables Body Mass Index (BMI), body fat percentage (% FAT) and the total weight of fat mass (in kg) in the body(FATMAS-kg) in favor of the subjects belonging to the older age group. The results indicate the existence of the problem of obesity inmales from Tuzla Canton, especially in the older age group. It is therefore necessary in adolescence or even earlier, to start with educationand systematic practice of sports and recreational activities with respect to dietary habits.KEY WORDS: Body Mass Index; Fat Tissue; Unemployed Men.

Background: This study was carried out among undergraduate students at the University of Tuzla (Bosna and Herzegovina) with the objective of examining gender differences in the body mass index (BMI) and the level of Physical Activity (PA) among respondents. Material/Methods: This study was conducted to: determine the body mass index (BMI) and the average weekly number of hours of sport activity in the last six months (PA). A research sample was made of female students (n=330) in the chronological age of 19.3+1.5 yrs, 60.7%, and of male students (n=213) in the chronological age of 20.0+1.8 yrs, 39.2%. Results: On average, the students (both female and male) spend 5.60 (5.03) hours on physical activity per week. Female students spend 4.05 (4.32) hours, while male students dedicate 8.11 (5.30) hours to physical activities. It can be concluded that in principle the students practice physical activities and recreation, but still 1/5 of all students are inactive. The obtained results for the BMI show that the majority of students are in the zone of normal values: female – 278 (84.2%); male – 157 (73.7%). Correlations between BMI and PA amount to (R=.214; p<0.01) and (R 2 =.046; p<0.01). The results of the T-test show a more significant statistical variable of differences between female and male students at the level of p<0.05. In comparison to female students, male students have 2.35 kg/m 2 higher BMI, and they are more active in physical activities for 4.06 hours in comparison to women. Conclusions: The focus should be directed to the education of young people, because they can easily adopt healthy habits that should be maintained for life. These results point out the necessity of an integrated approach to prevention and control of risk factors, particularly among youth.

The main goal of this study is to determine which of the applied kinematic parameters best predictor of accuracy in passing forearm. At the same time we want to establish the differences in the variables applied during the execution of the lower forearm pass to smaller and further away . The sample for this study is a 31 years old student of II study and cycle studies at the Faculty of Physical and sport of the University. All subjects were male average age of 21.66 ± 1.58 , average body height 180.37 ± 9.00 and an average weight of 76.43 ± 14.25. The video camera Casio Exilim EX-F1 was used for filming. The subjects were five times performed the technique on a smaller and five times farther away. To calibrate the space was used for calibration frame 1m x 1m x 2m. The camera was working at a frequency of 300 Hz resolution 720 x 576. The data was processed using a Kinovea software. On the basis of applied statistical analysis we can say that on the basis of certain kinematic parameters can make the prediction results in criteri variables in both groups. Also, it was found that there were statistically significant differences in the observed kinematic parameters between groups "Closer" and the group "Farther", and these differences are significance at the level .01 and .05. Consequently , our study is focused in order to obtain relevatinih information that will contribute to the understanding of the mechanical characteristics of the movement which ultimately contributes to more efficient training process . The results of our study indicate differences in kinemti?kim parameters when performing techniques of the lower forearm pass but in relation to the different position of the target. For faster and more efficient process of training the lower forearm passing volleyball, very important is the optimization of the angles of individual body segments as well as the defining characteristic of a breach during the execution of technical elements. This study allows us to obtain information that is relevant to the faster and more successful training techniques lower forearm passing. Key words: Kinematic, forearm pass, degree, distances

The main goal of this paper is a comparison of the percentagewise presence of the scores by the quality levels from the C.I. competition. Establishment of the differences between certain apparatus, competitions and judges’ commissions stems from the set goal. There is a big difference in the variability of results at Olympic Games, World and European Championship. Generally, the lowest average score at the competitions was on the pommel horse, and the highest one, on the vault. The article can provide useful information on the role of tactics in gymnastics competition in the team and all around competition.
