Method: A systematic review of relevant literature was conducted, encompassing various study types such as meta-analyses, systematic reviews, case reports, editorials, original research articles, and abstracts. Databases including PubMed/Medline, Web of Science, Taylor & Francis, and Google Scholar were comprehensively searched. The review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, utilizing a narrative synthesis approach due to the heterogeneity of collected data. Results: Carbohydrates emerged as a vital energy source for athletic performance. Adequate carbohydrate intake, appropriate timing, and nutrient composition were found to be critical for maintaining muscle glycogen levels during intense physical activity. Sports nutrition practices, such as high-carbohydrate diets and carbohydrate intake during exercise, have implications for athletes’ immune system status. Low glycemic-index carbohydrates exhibited benefits in endurance sports by promoting fat oxidation and reducing glucose oxidation. Gender-specific dietary guidelines were recommended to address substrate utilization differences during exercise. Conclusion: Nutrition, particularly carbohydrate consumption, significantly influences athletic performance and post-exercise recovery. The study underscores the importance of individualized nutrition plans, considering nutrient timing and composition, to optimize performance and overall well-being. Further research is needed to address limitations and establish conclusive evidence on the relationship between carbohydrate intake, recovery, and athletic performance. Overall, the research provides valuable insights for athletes, coaches, and practitioners aiming to enhance performance through effective nutritional strategies.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135867783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to evaluate the 12 different equations which are commonly using to determine resting metabolite rate (RMR) in the literature. Twenty-three female combat sport athletes (24.23± 3.39 years; 166.8 ± 5.3 cm; 63.13±6.53 kg; 8.78±3.19 experience years.; 56.40±3.43 VO2 mL/kg/min) were participated this study in voluntarily basis. A cross-validation approach used to compare the accuracy of 12 commonly prediction equations with measured RMR by indirect calorimetry to determine RMR in female combat sports athletes. All the predictive equation was underestimated RMR when compared with the measured RMR (p < 0.05) and the smallest mean difference (92.46 ± 210.38 kcal·d-1) was observed for Altman & Dittmer equation amongst the 12 predictive equations. The Altman & Dittmer equation was accurately predicted 16 out of 30 subjects’ RMR value within the range ±10%. However, based on the Bland–Altman plots, the prediction equations were not accurately nor precisely predicted RMR in the current sample of female combat sport athletes. The results in the present study showed that the Altman & Dittmer equation is most suitable equation to predict RMR amongst 12 equations. Although the Altman & Dittmer equation was resulted with smallest mean difference, it seems that there is need to further research with longitudinal approach to understand the effects of training intensity and body mass changes on RMR in order to develop the formulas already exist used commonly.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135867786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, monitoring youth fitness performance is crucial for identifying potential health risks and tracking physical literacy development. Over the years, many fitness test batteries have been developed while different protocols for footwear have been used in fitness testing. The comparison of fitness results performed in different footwear could therefore be questioned. Thus, the purpose of this study was to examine the differences between barefoot and shod performance of selected motor tests in adolescents. Eighty-six adolescents aged between 14 and 16 years performed standing long jump, 20-m shuttle run, and polygon backwards in both footwear conditions. A strong correlation (r=0.83-0.95) was noted between both performances. No significant differences between barefoot and shod performance in the standing long jump and the backward obstacle course test were found, while significant differences were noted in the 20-m shuttle run. In this test, both, boys and girls performed better in shod conditions. Interestingly, there were no significant differences in performance of all tests among those who are habitually barefoot and others. From practical perspective, this study demonstrated that researchers could compare scores of samples in barefoot and shod performance of standing long jump and backward obstacle course tests. However, when physical teachers compare individual scores over the years, this should be made under the same footwear conditions, as differences in test conditions can provide a distorted picture of motor development.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135867787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aerobic fitness was evaluated with a 20-metre shuttle run also known as Progressive Aerobic Cardiovascular Run (PACER) test which was used to estimate maximal oxygen uptake (VO2max) of participants. Body Mass Index (BMI) was also measured and a proforma was used to record PACER performance, gender, age and years of service. Mean, Standard Deviation and Linear regression were used for analyses. The Statistical Package for the Social Sciences (SPSS) version 25 was used for the data analysis. The findings revealed that the police officers had a mean VO2max of 46.01±8.644 ml/kg -1 ·minute -1. The police officers had a mean BMI of 25.68kg/m2, which was significantly associated (<0.001) with their VO2max. The study concluded that higher BMI is associated with decrease in VO2max. Gender had a significant relationship with the BMI of police officers, as female officers had higher BMI while male officers had lower BMI. Age had a significant relationship with the BMI of police officers, as their higher age is associated with their higher BMI. However, officers of both genders particularly females need to engage more in physical activities to have improved aerobic capacity and have their BMI within a healthy range.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135867784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to provide an analysis of offensive actions, by means of the Team Sport Assessment Procedure (TSAP) of the first four youth national teams during the 20th FINA Junior Water Polo World Championships. Twenty-nine elite youth (U20) water polo matches, involving the national teams of Greece (n=7), Serbia (n=7), Italy (n=7) and Croatia (n=8) were selected for the analysis. The TSAP included: i) two indicators of gaining possession of the ball; ii) four indicators of disposing the ball. Using these indicators, the following indices of technical performance were computed: Volume of Play (VP), Efficiency Index (EI) and Performance Score (PS). The field was divided in twelve zones. The one-way ANOVA showed no significant differences between teams for all parameters (p>0.05), except that for Offensive Balls (OB) and Successful Shots (SS) occurred in specific zones of the field: for OB significant differences were found in zone 1 (p=.019), in zone 2 (p=.014) and in zone 5 (p=.007); for SS significant differences were found in zone 1 (p=.026) and in zone 2 (p=.008). The main reason of between-teams differences could be explained by the presence of a left-hand player in the game, and by the tactical behaviour of coaches and players. The TSAP instrument could offer productive feedback to coaches to perceive the different requirements of playing and to evaluate how players understand the game.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135867844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These athletes often complain of pain and report unexplained loss of throwing velocity and throwing control. Shoulder dyskinesia and overuse syndrome have been identified as risk factors among elite handball athletes. Understanding the dynamics and kinematics of the throwing phase is vital for the exercise professional. This study evaluates the effect of an interventional exercise program on shoulder girdle biomechanics and overhead shooting. The sample consisted of 20 high level handball athletes from Greece. The athletes were divided into two groups: 10 in the study group, who were given the exercise program, and 10 in the control group, who only engaged in in-team handball training. Before and after the program, the following measurements were performed: a) angular measurements of abduction, adduction, flexion and extension of the shoulder; b) isokinetic evaluation of abduction flexion and adduction extension of the shoulder joint, at three angular velocities (60°/sec, 180°/sec and 300°/sec). Inferential statistics showed that there was a statistically significant difference in angular measurements with a reduction in range of motion for 10 of the study group. In the isokinetic assessment there was a statistically significant difference, in the 180°/sec velocities in flexion and extension, and in the deficit of flexion of both shoulders. In conclusion, the interventional exercise program had, to some extent, a beneficial effect on muscle strengthening of the shoulder girdle. The results of this study may suggest training guidelines, provide important information to exercise professionals, and provide feedback to handball athletes.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135867842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to demographic characteristics, the survey included question to sports activity, issues related to hostilities, standardized questionnaires to measure life satisfaction (SWLS), perceived stress level (PSS-10), depression (PHQ-9), anxiety (GAD-7), physical, mental and social functioning (SF-36). Statistical analysis included descriptive statistics, correlation analysis to find association between variables, and building linear regression models. Samples of young and adult athletes that we analyzed did not differ in terms of life satisfaction. Among young athletes there were significantly fewer people with symptoms of stress (67%) and anxiety (25.53%). Three groups of factors that determine the life satisfaction of young Ukrainian athletes can be single out: individual (stress, depression), contextual (change of place of residence or training due to the war), and health-based (general perception of one’s own health and pain sensations). The data highlight the critical importance of mental health monitoring for the overall well-being of athletes.

The aims of this study are twofold: (1) to examine bilateral asymmetries in isokinetic strength and balance assessments, and (2) to evaluate the relationship between muscle strength and balance measures. Eighty-eight male adolescent football players were assessed for body composition (InBody 770), isokinetic strength (Biodex System 4 Pro Dynamometer), and balance performance (Biodex Balance System). Paired samples t-tests were conducted to determine bilateral differences in strength and balance. Pearson correlations and multiple linear regression analyses evaluated the relationship between strength and balance. No significant bilateral strength differences were observed in knee flexors (KF) and knee extensors (KE) peak torque (PT) scores. No bilateral differences were found for balance measures, except in the lateromedial stability index, which was better while performing with the preferred leg (p ≤ 0.01; d = 0.29). Significant correlations were found between KE PT and balance tasks (p ≤ 0.01). KF and KE PT shared between 18 and 22% of the common variance in the overall stability index in the non-preferred and preferred leg, respectively. Monitoring strategies of bilateral asymmetries may be crucial to enhance performance in tasks underpinned by unilateral movements, such as changes of direction and sprints, and to identify players at risk of injury. Adopting these strategies during the early stages of football training might be crucial for players’ long-term development.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135867782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
