Introduction: This study aims to establish the validity-reliability of the Turkish version of adult e-Healthy Diet Literacy Scale and to determine its relationship with the Health Literacy Instrument Scale (short-form), the Digital Healthy Diet Literacy Scale, and participants’ characteristics. Ma-terial and Methods: Drawing on a methodological and descriptive design, this research was per-formed in two steps. It was conducted with 240 participants in the first step and 879 participants in the second step. The participants filled out the eHealthy Diet Literacy Scale, Health Literacy In-strument Scale (short-form), and Digital Healthy Diet Literacy Scale. The questionnaire form was sent to the participants online. Results: Cronbach’s alpha coefficient for the 11-item e-Healthy Diet Literacy scale was found to be 0.555. There was a significant relationship between the Health Literacy Instrument Scale (short-Form) and age groups, educational level, occupations, marital status, BMI, weekly physical activity and chronic disease status. Conclusions: This study evaluated the Turkish validity and reliability of the e-HDL, which was originally designed in Taiwan as a valid and reliable tool to evaluate the individuals’ ability to access, understand, appraise, and apply healthy diet information.

Introduction: Sports injuries are the most common cause of anterior cruciate ligament (ACL) ruptures. Previous research has demonstrated links between some of the COL27A1 and COL11A1 genetic variants and musculoskeletal soft tissue injuries. However, no previous research has investigated the COL27A1 rs1570460 and the COL11A1 rs3753841 in the context of ACL rupture in any population. Thus, our study aimed to assess the association between specific single nucleotide polymorphisms (SNPs), i.e., COL27A1 rs946053 and COL11A1 rs3753841, and the occurrence of ACL injury (ACL-I) in a cohort of Polish athletes. Methods: The study enrolled 233 athletes with ACL-I (161 males and 71 females) and 228 healthy control athletes (143 males and 85 females) with no prior ACL-I history. Genotyping was conducted to assess the presence of COL27A1 rs946053 and COL11A1 rs3753841 genetic variants. Statistical analyses were performed using the R programming environment and package, and an association between SNPs and ACL-I was tested in four genetic models: dominant, co-dominant recessive, and over-dominant. Results: All the analyzed polymorphisms conformed to Hardy-Weinberg equilibrium (HWE). The study revealed no significant differences between the ACL-I and control groups. Conclusions: Despite the absence of significant associations between the investigated SNPs and ACL-I in this study, our findings highlight the importance of continued research to unravel the precise genetic risk mechanisms and etiological factors contributing to ACL-I.

Introduction: The purpose of the study was to investigate the age-related anthropometric and motor performance changes over time and their contributions to swimming style-specific performance in young different chronological age swimmers. Material and Methods: The study was conducted on a total of forty swimmers who were divided into 2 groups. The Anthropometric meas-urements were executed from 12 body parts, and body composition analysis was determined by using the skinfold method. The motor performance tests were performed for the assessment of standing horizontal jump, handgrip strength, flexed-arm hang strength, sit-up, flexibility, aerobic endurance, speed, agility, and balance. Simple Linear Regression analysis was performed to build the models for each of the swimming styles. Results: All the models indicated that aerobic endur-ance was a significantly predictive variable on all swimming styles (p < 0.001). The results indicated that the anthropometric and motor performance predictors changed depending upon the age pro-gression in each swimming style (p < 0.001). Conclusions: The effect of many variables on swimming performance is seen to be more evident in the following periods based on the increase of age. Aerobic endurance is a common variable that shows effectiveness on swimming performance for both all age groups and swimming styles.

Introduction: This study aimed to determine the variables that predict whether WHO's global recommendation for physical activity (PA) before and during the COVID-19 pandemic can be met among adults. Material and Methods: A total of 921 adults voluntarily participated in this study. A demographic information form and the Physical Activity Assessment Questionnaire for Turkish people were administered by self-report. The participants were also asked whether they regularly do PA and if the duration of PA is over 150 minutes. Results: The number of adults doing regular PA at the level recommended by WHO significantly decreased during the COVID-19 pandemic, and the rate of not doing regular PA significantly increased compared to the period before the COVID-19 pandemic (p<0.05). Variables that reduce the likelihood of doing regular PA at the recommended level include being male, being under 45 years old, being married, having high school education or below, having a moderate and low-income, having a high BMI, and having a high recreational sedentary screen time (RSST) during the COVID-19 pandemic. Conclusions: The results of this study provide a priori information for implementations aimed at improving the recommended PA level for adults during social isolation or lockdown.

Introduction: During the COVID-19 pandemic managers experienced additional stress connected with taking responsibility for workers at the time of a worldwide crisis. Maintaining a high level of physical activity in this specific group possibly could have contributed to keeping both management skills and health condition at a high required standard. The purpose of this review is to verify the range of scientific interest on the subject of physical activity among managers as a stress coping strategy during the pandemic. Materials and Methods: For this systematic review six studies were chosen (two of them are qualitative descriptive, three are cross-sectional, one is a report). The inclusion criteria were as follows: studies focusing on stress, physical activity and managers; studies conducted in the years of COVID-19 epidemic available in full-text. The exclusion criteria applied to studies where the managers’ group was not specified. The number of study participants ranged from 20 to 255. Results: The frequency of exercise was insufficient and unsuitable to the managers’ specific needs, especially during the demanding time of the COVID-19 pandemic. Conclusions: The managers were highly aware of the role of sport in lowering stress and improving health, especially during the pandemic. However, this has not resulted in more frequent physical activity among this group. There is a high probability that further confronting the leaders with their real physical activity daily habits would have influenced their reflection about the subject and initiated change.

Introduction: Hamstring injuries are common in physically active people and athletes. Lack of hamstring flexibility is the one of the most important characteristics of hamstring injuries in athletes. The aim of this study was to investigate effects of three different stretching techniques on hamstring flexibility in professional football players. Materials and Methods: Fifty-five male football players between the ages of 18–20 years old were involved in the study. The participants were divided into 3 groups: static stretching, neuromobilization and Mulligan traction straight leg raise (TSLR), respectively. Each participant’s dominant lower extremity was assessed with a straight leg raise test (SLR) using a goniometer before and after the intervention. Results: There was a significant difference in the SLR range of motion before and after the intervention in all groups. There was no difference in the range of SLR between the groups at the beginning and at the end. However, the increase in the SLR range of motion was significantly higher in the Mulligan TSLR group. Conclusions: It was concluded that all 3 stretching techniques are effective in increasing hamstring flexibility in football players. However, the Mulligan TSLR technique could provide a greater increase in the range of motion than other techniques.

Introduction: This study investigated the differences in ACTN3, ACE and ADRB3 variants in top-level soccer players who entered the Croatian National Team and the ones who did not but played for two best Croatian teams. Material and Methods: The buccal swabs were collected from 56 soccer players playing for the Croatian National Team (N = 31) and/or for one of the two most prestigious Croatian soccer clubs (N = 25). Each participant’s genotype was determined by analyzing the single-nucleotide polymorphism. The ACTN3 gene (rs1815739) on chromosome 11 and the ACE (rs1799752) gene on chromosome 17 were determined. Results: No significant differences between the players who entered the national team and the ones who did not were found in ACTN3 R577X (p = 0.437) and ADRB3 (p = 0.202) polymorphism distribution, while the differences existed in ACE (p = 0.044). The significant differences were determined in the “Athletic index” between the national-team and non-national-team players (p = 0.023). Regarding the position, the “Athletic index” was significantly higher only in national team midfielders (2.50 ±1.08 points vs. 1.38 ±1.06; p = 0.034). Conclusion: It seems that the soccer players with a favorable genetic combination on the ACTN3 gene and ACE gene might have had a better chance to enter the National Team.

Introduction: Anterior cruciate ligament (ACL) injuries are among the most common ligament injuries of the knee and often require reconstruction. The etiology of the molecular mechanisms of rupture of the anterior cruciate ligament (ACL) is poorly understood, and many external and internal factors have been associated with it, including genetics. This study aimed to investigate the association of sequence variants in the ELN and FMOD candidate genes with ACL ruptures based on the essential biological functions of these two proteoglycan-encoding genes in maintaining the structural integrity of tissues and regulating fibrillogenesis. Material and Methods: The partici-pants consisted of 229 (164 male and 65 female) individuals with a surgically diagnosed ACL rup-ture (ACLR) who qualified for ligament reconstruction and 192 (107 male and 85 female) healthy participants with no history of ACL injury (CON group). All 229 participants in the ACLR group sustained injuries through non-contact mechanisms. The chi-square tests were used for association analysis of ELN rs2071307 and FMOD rs7543148 between the anterior cruciate ligament rupture (ACLR) group and the control (CON) group. Results: It follows from the study that the tested group of athletes shows a statistically significantly more frequent AA genotype in the ELN rs2071307 gene polymorphism than the control group. However, looking at gender, one can observe that these are significantly more frequent. In the polymorphism of the FMOD rs7543148 gene, a significantly rarer TT genotype was observed in the study group compared to the control group and, similarly to the previous polymorphism, the TT genotype was significantly less frequent in the group of males com-pared to the control group. Conclusions: Genetic research in sports, especially concerning injuries connected to characteristic polymorphic variants of selected genes, is justified, particularly as regards gender-homogenous groups.

Introduction: The aim of this study was to determine whether the relative age effect (RAE) was present among handball players participating in the Tokyo 2020 Olympics. Materials and Methods. The study involved a group of handball players participating in the Tokyo 2020 Olympics. All data was collected from the website of the IHF. The research material consisted of data on the players’ dates of birth, which were broken down by four quarters (Q1: January 1–March 31, Q2: April 1–June 30, Q3: July 1–September 30, Q4: October 1–December 31) and two semesters (S1: January 1–June 30, S2: July 1–December 31). The following independent variables were used: game position, continent and world region. Differences between the dates of birth were determined using the chi-square test. To determine the strength of correlations, Cramér’s V was used. Results. In general terms, the main factor differentiating the RAE among handball players participating in the Tokyo 2020 Olympics was the geographical location of the country they represented (continent). There was no RAE among female handball players. Among male handball players, the RAE was differentiated by the region of the world (Europe, others). Conclusions. In order to thoroughly investigate and describe the RAE, further research and the search for factors that differentiate it should be carried out.
前言:本研究的目的是确定参加2020年东京奥运会的手球运动员是否存在相对年龄效应(RAE)。材料与方法。这项研究涉及一组参加2020年东京奥运会的手球运动员。所有数据均从国际卫生联合会网站收集。研究材料包括球员的出生日期数据，分为四个季度(第一季度:1月1日至3月31日，第二季度:4月1日至6月30日，第三季度:7月1日至9月30日，第四季度:10月1日至12月31日)和两个学期(第一学期:1月1日至6月30日，第二学期:7月1日至12月31日)。使用了以下自变量:游戏位置，大陆和世界区域。出生日期之间的差异使用卡方检验确定。为了确定相关性的强度，使用了cram s V。结果。总的来说，区分参加2020年东京奥运会的手球运动员的RAE的主要因素是他们所代表的国家(大陆)的地理位置。女子手球运动员无RAE。在男子手球运动员中，RAE随世界地区(欧洲，其他地区)而有所差异。结论。为了更深入地调查和描述RAE，应该进行进一步的研究和寻找区分它的因素。

Materials and Methods. The study involved a group of handball players participating in the Tokyo 2020 Olympics. All data was collected from the website of the IHF. The research material consisted of data on the players’ dates of birth, which were broken down by four quarters (Q1: January 1–March 31, Q2: April 1–June 30, Q3: July 1–September 30, Q4: October 1–December 31) and two semesters (S1: January 1–June 30, S2: July 1–December 31). The following independent variables were used: game position, continent and world region. Differences between the dates of birth were determined using the chi-square test. To determine the strength of correlations, Cramér’s V was used. Results. In general terms, the main factor differentiating the RAE among handball players participating in the Tokyo 2020 Olympics was the geographical location of the country they represented (continent). There was no RAE among female handball players. Among male handball players, the RAE was differentiated by the region of the world (Europe, others). Conclusions. In order to thoroughly investigate and describe the RAE, further research and the search for factors that differentiate it should be carried out.","PeriodicalId":43798,"journal":{"name":"Baltic Journal of Health and Physical Activity","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78998347","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}
Introduction: Technology determines the emergence of functional tools to monitor and control motor activity during the game. One of the solutions for monitoring the player in indoor sports are computer video analyses, which determine basic kinematic parameters. The study aims to compare team and player activity with the outcome of a given set and the effect of the game status on player activity during a championship-level match. Materials and Methods: The study analysed 140 volleyball players aged 19 to 40 years (27.05 ± 4.33 years, height: 197.15 ± 9.63 cm, body mass: 88.51 ± 9.23 kg) participating in the FIVB Volleyball Men's World Championship. The observed matches were categorised by score (3:0, 3:1, 3:2 and 0:3, 1:3 and 2:3). Depending on winning or losing, each set was described as W – a winning set, P – a losing set and O – as the first set. Results: The average distance covered in all observed matches was 10.7 ± 0.09 m, while for matches completed in 3 sets, it was 10.48 ± 0.13 m. Attackers covered the longest distance in action (11.43 ± 1.68 m), while the libero covered the shortest distance from among all observed players (8.79 ± 1.91 m). The losing teams covered a significantly greater distance in action (10.87 ± 2.24 m) in action than the winning teams (10.54 ± 1.91 m). Conclusion: The results of this study allow the conclusion that teams winning sets cover a smaller average distance in action than their opponents. The highest covered distance was observed in the first set and in sets 4 and 5 when teams were losing a set after losing the previous one. The smallest distance was covered by teams that lost set 5 after winning the previous set.
