This study was conducted to investigate the relationship between grip strength and aerobic capacity in healthy sedentary young females. Forty healthy, young, and sedentary females participated in the study (20.5±1.5 years). Body composition was assessed with the bioelectrical impedance method. The hand-grip strength of the individuals was measured with a hand-grip dynamometer. An indirect graded arm crank ergometer test was used to determine the peak oxygen uptake (VO2 peak). It was found that the grip strength was correlated with height (r=0.51, p=0.001), fat-free mass (r=0.45, p=0.004), and VO2 peak (r=0.36, p=0.023); however, there was no correlation between grip strength and body weight, body mass index, and body fat percentage (p>0.05). VO2 peak was negatively correlated with body fat percentage (r= -0.38, p=0.016) and body mass index (r= -0.30, p=0.045). The results showed that higher muscle strength and fat-free mass are related to higher aerobic capacity. It is considered that increasing muscle strength and fat-free mass as well as decreasing body fat may be an appropriate strategy to increase cardiorespiratory fitness.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"78 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78881347","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}

Eight semi-professional male players were monitored using accelerometers. For all quarters, peak intensities were determined via moving averages for PlayerLoad/minute (PL·min-1) using sample durations of 15 s, 30 s, 1 min, 2 min, 3 min, 4 min, and 5 min. Linear mixed models and effect sizes (ES) were used to compare peak intensities between quarters for each sample duration. Small decreases in peak PL·min-1 occurred between Quarters 1 and 4 for all sample durations (ES = 0.21-0.49). Small decreases in peak PL·min-1 were apparent between quarters 1 and 2 for 30-s, 1-min, and 3-min sample durations (ES = 0.24-0.33), and between quarters 3 and 4 for 2-5-min sample durations (ES = 0.20-0.24). Peak intensities decline across quarters with game progression in basketball, providing useful insight for practitioners to develop game-specific training and tactical strategies.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"16 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87607043","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}

While health-related factors present valid and reliable tests, the skill-related component should be studied in depth. An interesting test to evaluate the skill-related factors is the Harre circuit test (HTC); unfortunately, this test includes the somersault, an element not present in soccer. The aim of the present study is the validation of the Petrucci ability test (PAT), a variation of the HTC without the somersault for young soccer players. Children and adolescents (age range 10–13 years old) soccer players concluded the 20-m, the HTC and the PAT. To establish the validity of the PAT, correlation analysis has been performed, which presented a p < 0.0001 between PAT and HTC; p < 0.001 between PAT and a 20-m test; and p < 0.0001 between HTC and the 20-m test. The results suggest that the PAT can be a valid substitute for the evaluation of the skills-related components of young soccer players and, consequently, also of athletes and schoolchildren.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"23 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76139452","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}

Nevertheless, the mechanisms of concussion in sport have are not precisely known. Thus, this study aimed to investigate the dynamic response of the head based on linear and rotational accelerations in boxing using computer simulation. The ADAMS software model was used to determine the linear and rotational acceleration of boxing’s straight punch. The peak linear acceleration, average linear acceleration, peak rotational acceleration, and average rotational acceleration resulted from the straight punch to head were obtained: 75 g, 20 g, 4036 rad/s², 1140 rad/s², respectively; the impact times were 30 ms and 3 ms, respectively. The comparison of acceleration tolerance thresholds of head injury and obtained results of this study showed the rotational acceleration only leads to head injury. Furthermore, it is biomechanically improbable that the head would be moved only translationally or rotationally as a result of a straight punch. Therefore, both rotational and linear accelerations should be observed together for future studies.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"22 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89590610","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 the present review was to determine which psychological factors affect the success of rehabilitation and return to sport following the most frequent musculotendinous thigh injuries (hamstrings, hip adductors, knee extensors), and to present the main psychological screening tools and interventions that can aid the athlete’s rehabilitation and return to sport. A systematic review of the literature did not reveal any relevant results related to those injuries; therefore, the search was expanded to whole lower limb injuries, which showed that several different psychological factors could have a significant impact on an athlete’s rehabilitation and decision to return to sport. It can be presumed that these factors can similarly affect the post-injury process for thigh injuries, which should be considered when planning the rehabilitation programme. Systematically implementing psychological screening and psychological interventions (if needed) into the already established rehabilitation protocols would be reasonable for optimizing an athlete’s recovery and for helping with the decision to return to sport.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"1 1","pages":"59-64"},"PeriodicalIF":1.3,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82253504","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}

This study aims to determine whether the influence of the RAE can be proven in the Czech youth ice hockey league (U15) (n=744). A Chi-Square test (χ2) has shown that the influence in the whole investigated group cannot be rejected (χ2=25.34, p<0.01, w=0.11). The RAE can be rejected in the group of players (n=78) from the three best teams of the competition (χ2=3.09, p=0.38, w=0.11); the influence of the RAE can also be rejected in players (n=75) from the three worst teams (χ2=0.53, p=0.91, w=0.05). The assessment of RAE on playing positions has shown that the RAE can be rejected (χ2=7.31, p=0.06, w=0.22) in the most productive forwards (n=50) as well as in the least productive forwards (n=50) (χ2=0.48, p=0.92, w=0.06).

An electronic search on five databases (PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, SportDiscus, and Physiotherapy Evidence Database (PEDro)) was conducted. Studies were included if (1) patients suffered from tendinopathy; (2) isolated KT was applied in at least one group; (3) comparisons between other techniques were developed; (4) outcomes based on pain, function, disability, or quality of life were analysed. Two reviewers independently extracted data and assessed methodological quality using the Physiotherapy Evidence Database (PEDro) scale. A total of 13 articles met the eligibility criteria, involving 454 participants. Nine of these studies presented upper extremity tendinopathies, and four explored lower extremity tendinopathies. Selected papers ranged from low to high quality, with an average score of 5 on the PEDro scale. According to our findings, there is limited evidence to support KT alone for the treatment of tendinopathies beyond the short-term. Due to the mixed methodological quality and the insufficient number of clinical trials, larger, long-term, high-quality studies are needed to support the theory that tendinopathies can benefit from KT applications.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"79 1","pages":"73-86"},"PeriodicalIF":1.3,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72808622","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}

Accordingly, it is necessary to employ a maximum voluntary isometric contraction (MVIC) position that elicits the highest activation to increase the validity of EMG studies and provide accurate comparisons between studies. Therefore, the purpose of this study was to compare the peak electromyography (EMG) of the most commonly used positions in the literature (i.e., the fully extended hip and knee, hip-flexed 45°, and knee at 90°) to a novel position: prone hip extension with 90° knee flexion. An ultrasound imaging system was used to guide the surface EMG electrode placement on the adductor magnus (AM) muscle, for a group of ninety-four recreational runners. AM demonstrated the greatest MVIC activity in both prone and hip-flexed 45° positions with no significant differences between them (p < 0.05). However, significant differences were displayed between the AM activities while performing the fully extended hip position and the other two positions. Based on these results, it is recommended that the prone and hip-flexed 45° positions can be used to measure the MVIC of the AM interchangeably. Furthermore, the prone position can be considered to be a position of the greatest MVIC of AM, particularly when the position of hip-flexed 45° is limited as well as it can be used to quantify MVIC for both AM and hip extensor muscles simultaneously.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"25 1","pages":"21-26"},"PeriodicalIF":1.3,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81630465","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 exercise programme consisted of walking, brisk walking, jogging, and running for three months, during which the intensity and duration of exercise were gradually increased. All the patients performed the exercise programme at 6.30 AM to exclude the effects of the circadian rhythm. The exercise programme was performed at an intensity below 160 beats per min to ensure filling of the heart with blood during ventricular diastole. Blood samples were collected from each patient on three occasions: before treatment, at the end of cabergoline therapy, and after the combination of light exercise and cabergoline. At the end of cabergoline therapy, descriptive data revealed that serum prolactin levels were decreased while the other hormones were increased but without returning to the normal range, except for one patient. However, at the end of the combination procedure, most hormones, namely prolactin and testosterone, were returned to the normal range in most patients. In conclusion, light exercise combined with cabergoline therapy for additional 3 months after 6 months of cabergoline therapy alone returned hormones in most patients to normal range probably due to improved mood and decreased hostility as a result of tuberoinfundibular pathway activity.","PeriodicalId":18942,"journal":{"name":"Montenegrin Journal of Sports Science and Medicine","volume":"204 1","pages":"35-41"},"PeriodicalIF":1.3,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76050948","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}
