The goal of this paper is to determine the injury frequency rate in professional football players in leagues and national competitions by analyzing existing papers. We have chosen 21 articles according to the PRISMA method from the Google Scholar, ResearchGate Scopus, and Web of Science databases that fit both inclusion and exclusion criteria. We have discussed the following four segments based on the content of the selected papers: 1) An analysis of the injury frequency rate on the level of national teams, 2) An analysis of the injury frequency rate in club leagues, 3) A comparison of the injury frequency rate in matches and in practice, and 4) An analysis of the injury frequency rate in male versus female football players. The paper concludes that major national team tournaments have the highest injury frequency rate and that the probability of injury is four to five times higher in a match than in practice. The injury frequency rate in female players is lower than in male players regardless of the type of competition (national teams or leagues).

Objective: Identify the factors that influence the adherence of Resisted Training programs in gyms located in the city of Guaratuba, Paraná/BR. Methodology: The design of the present study is cross-sectional. A total of 100 Resisted Training practitioners of both genders, aged between 18 and 75 years, participated in the research. The location for data collection included four gyms located in the city of Guaratuba-PR. Considering the nature of the research, it was chosen to apply a questionnaire adapted from Morales (2002), composed of opened and closed-ended questions. The instrument was composed with exposure variables of sociodemographic, economic, environmental factors, self-perception of lifestyle and health, stress levels indicators and physical activity. The SPSS® 16.0 program was used for statistical treatment. Considering the non-normality of the data distribution through the Kolmogorov-Smirnov test, Spearman’s correlation test was used and values of p<0.05 were considered significant. Results: The present study showed three significant moderate correlations, demonstrating a joint variation of tobacco use with alcohol (0.655 with p-value<0.05), intake of high alcoholic beverages over others (0.802 with p-value<0.05), and men’s weekly workload (0.62 with p-value<0.05). Conclusion: According to the obtained data, it’s possible to conclude through the significant moderate correlations, that the sociodemographic aspects and the identification of some behavioral risk factors related to the use of tobacco and alcoholic beverages, can influence the adherence to the training programs in gyms.

HIV is a debilitating infection that often presents with health-related complications, further reducing quality of life. Of the most common comorbidities accompanying HIV is depression, which can induce cognitive alterations alongside those resulting from the virus. Latinxs are disproportionately susceptible to both afflictions and face innumerable challenges in the identification and diagnosis of depression. Consequently, HIV-infected Latinxs may experience additional cognitive symptomatology from the simultaneous prevalence of depression and HIV, potentially affecting their gait and cardiovascular profiles. This study aimed to determine the impact of depression on cardio-motor components in HIV-infected Latinxs. Records of 291 stable HIV+ participants were collected from La Perla de Gran Precio Community Center, analyzed for depression, and respectively allocated to the depression group (70) and the group without depression (221). Cardio-motor values were obtained by conducting the Ross treadmill test, a submaximal cardiovascular assessment. An ANOVA revealed similarities in cardiomotor profiles between groups, alluding to the absence of depression-induced modifications to gait and cardiovascular health. Community exercise and cardiopulmonary intervention programs are beneficial to the quality of life in this population during all stages of HIV. However, HIV-infected Latinxs with depression face acute cultural challenges, causing diagnoses and treatment oversights and deficiencies for those who are suffering. Public health efforts should aim to remove barriers facing this population to ultimately reduce the inflated prevalence of both afflictions. Future research should focus on the crucial differentiation of Latinx depressive symptoms from those identical in HIV prior to reinvestigating cardiomotor alterations.

Over the past few years, energy drink consumption has increased among students aged 18–34 years. Energy drinks alter the balance, reduce blood flow and interfere with neuromuscular activation in the lower extremities. We attempted to determine which specific additive of three different drinks (red bull, rockstar, and bang) could contribute to changes in muscle activation of the ankle complex. Twenty healthy young adults aged 22–28 years were included in this study and allocated among 3 groups, red bull, rockstar, and bang. Neuromuscular data were obtained from EMG sensors positioned on the anterior tibialis and gastrocnemius before completing the four balance tasks. Each participant completed all the tasks before and after the 16-ounce Edrink. ANOVA was performed to compare the data before and after the beverage. Statistical significance was set at P <0.05. A trend was observed in red bull and bang groups revealing a faster anterior tibial activity and prolong activation for gastrocnemius. The rockstar group also showed a more rapid activation trend and shorter response during all tasks for the gastrocnemius. It appears that the additives found in Redbull and Bang produce an increased posterior sway, indicated by the faster activity observed on the anterior tibial muscle. On the other hand, the elements encountered in rockstars provoke anterior movements, creating the need for a quicker response from the gastrocnemius muscle. Further research is required to explore certain energy drink ingredients' effects on dynamic activities such as walking.

Diabetes is recognized to lead to a series of metabolic abnormalities in the body. These alterations will affect balance, body composition, and cardiovascular performance, heightening the risk of various medical complications. The problem is that the primary instruction for those with diabetes is to monitor glucose levels, paying very insufficient consideration to other fundamental factors and health profiles that could influence the quality of life in these individuals. Identify body composition, balance, and cardiovascular components in controlled type two diabetics compared to an age-matched control group. 15 participants with controlled type II diabetes without peripheral neuropathy (CT2DM) and 18 non-diabetic subjects control (CG) were recruited. Both groups had an age average of roughly 56 years old. The CT2DM subjects had an average A1c level of 6.7+/-0.5%. Body composition, cardiovascular, and balance data were collected, analyzed, and compared among groups. Minimal alterations in balance components, body composition and cardiovascular factors were identified in the CT2DM group aside from higher SBP values and decreased BBS scores contrasted to the CG group. We can attribute the analogous outcomes in both groups to CT2DM participants managing their diabetes effectively. Our examination has prompted us to establish that the cardiovascular and balance components in middle-aged Latinx-Hispanic participants with CT2DM are proportionate to CG subjects because of effectiveness in dealing with diabetes. Further, we encourage establishing more age appropriate and complex assessment tools to identify early adaptations caused by diabetes.

Resistance training has been commonly used as a method of intervention in the rehabilitation of musculoskeletal injuries affecting the knee. Thus, the objective of this systematic review was to identify the methods employed with and without implements in leg press and squat exercises for the maintenance of knee alignment. The literature search was performed in the databases: PubMed, SciELO, and Lilacs. We used the descriptors "muscle strength" and "exercise" and their synonyms, available in the Health Sciences Descriptors (DeCS) and the Medical Subject Headings (MeSH), with the terms "valgus knee" and "varus knee". From the 1,117 articles found, eight studies were considered for the review. The included studies had samples composed of young men and women with advanced levels of training. Despite verifying conditions of valgus or varus knee, the studies presented different protocols and assessment methods. The implements comprised physioball, elastic resistance, and wedge. Electromyography and kinematics were used to assess muscle activity and movement patterns. These results reinforced the possibility of using implements to induce muscle and joint actions to reduce varus and valgus conditions. We suggest more studies to define the best strategies to reduce the excessive deviation of the patella in people who have valgus or varus knee.

To examine long term changes on glycated hemoglobin in sedentary employees exposed to two different walking programs during a 10-week intervention. A total of 68 sedentary employees participated in a 10-week walking intervention and were randomly assigned to one of three groups: intermittent walking, continuous walking or control group. Hemoglobin A1cNOW+ device tested glycated hemoglobin and accelerometry assessed physical activity. Results showed glycated hemoglobin significantly decreased over the ten weeks (5.82±0.49, 5.66±0.44) F(1,64) =4.229, p=.044) in the continuous walking group. Post-Hoc test showed the continuous walking group was significantly affected, F=8.463, p=.009, with a large size effect n2=.297. There were no changes within the intermittent group (5.69±0.63, 5.63±0.6) or control group (5.59±0.6, 5.6±0.54) (p>0.05). Accelerometry showed a main effect of time by group interaction F(4,124) =4.688, p=0.001). Post-Hoc indicated that the continuous walking group took significantly longer bouts of moderate to vigorous intensity walking at week-6 compared to pre-test (p=0.006) at this could have influenced the results, there were no changes in the length of bouts in the intermittent or control groups (p>0.05). Sedentary employees who perform a moderate intensity continuous walking program show benefits in controlling blood glucose, thereby, reducing the risk of developing type 2 diabetes.

To determine the effects of a virtual physical activity (PA) program in college students during social distancing due to COVID-19. 44 college students, male and female. Methods: Participants completed self-reported measures of the International Physical Activity Questionnaire, weekly PA, and a short-survey of the educational experience during social distancing. Participants completed the instruments at baseline and after 10-weeks of an on-line virtual PA program. Increased overall PA (p = 0.040) and transportation PA (p = 0.004), leisure-time PA (p = 0.031) domains increased following the program. The sitting time increased following the intervention (p = 0.0001). Students who failed to comply with at least 150 min/week of PA reduced the frequency of positive emotions compared to those who complied (p = 0.017). Social distancing and daily college tasks seem to lessen the effect of PA on sedentary behavior in college students regardless of an increase in PA.

The purpose of this study was to investigate the impact of coach leadership style on resilience level of volleyball players and to trace possible differences that exist between the two genders. Participants included 101 volleyball players (53 females and 48 males) and 31 coaches (11 females and 20 males), with the Self Evaluation Resilience test and the Leadership Scale for Sport (LSS) used as instruments. The data was analyzed with SPSS 21.0 using t-test for independent samples, and simple regression (stepwise) analysis. Results of t-test showed statistically significant differences between male and female volleyball players in ‘‘orientation on solution and aims’’ and ‘‘self-efficacy’’ variables, with no other statistically significant differences observed for the rest resilience variables. Additionally, no statistically significant differences were observed for the LSS variables between the two genders of volleyball coaches. The results of simple regression (stepwise) analysis suggest that the autocratic behavior of volleyball coach has a significant impact on volleyball players’ resilience. Future research should investigate whether variables such as anxiety affect the resilience level of volleyball players.

The development of instruments and the use of the same is expanding from year to year. The paper aims to determine the usefulness of Myotesta (MT), Optojump (OJ), Globe Ergo System (GES) as modern methods for assessing motor performance. The research included nine original scientific papers. All works satisfied the problem and could answer the set goal. The selection of works from 2009. to 2014. was taken as a method. There are specific differences when comparing the results for each of the instruments. Myotest has stood out as the smallest instrument and is easily portable and therefore effective to use. The assessment of explosive power is easy to perform, and the results it gives are reliable.
