A Comparison of Some Important Biochemical Indicators According to Escalating Physical Effort till Fatigue for Elite Freestyle Wrestlers, 800m Runners, and 200m Freestyle Swimmers

It is the nature of the game and the activity that determines the characteristic of the manifestation of fatigue according to what is required by the neuromuscular work in it, as well as the changes that occur in the functional variables and the time of the differential threshold. The location of each activity and the game of these teams have been studied in a special table for energy production systems as a result of continuous changes in their laws, and are considered within the energy systems such as the anaerobic system (Phosphagine) and lactic acid for (800) m runners - freestyle swimmers (200) m in the physical effort till fatigue. The comparison in the important functional indicators for them, and the research methodology embodied in the way of working through the method used, which is the descriptive method in comparison then, the researchers identified the research community for the young national team athletes for freestyle wrestling, and the national team(800)m runners, as well as of the national team in (200) m swimming for the sports season (2022-2023), A total of 21 athletes were selected in an organized manner and distributed into three equal groups (7 athletes) for each of the three types of sports (wrestler, 200-meter swimming and 800-meter running)., and the researchers would conduct tests for the research variables biochemical for the sample members, as well as some variables that have an impact on the results of the study such as (height, age, weight, and the age of training ), and the homogenization of the research sample members was carried out. The results of statistical treatments were presented, analyzed, and discussed, supported by sources. The most important conclusions were that most of the activities and the variation of values are very essential biochemical indicators. The differences were significant and the positive variation in accordance to the type of sport or activity, and the last variation between the activities in terms of comparison in these variables is due to the nature and specificity in terms of the intensity of the resistances and direct and indirect friction For competitors and the expenditure of energy stored in muscles. Finally, the researchers recommended knowing the most important biochemical indicators in these events and sports as they reflect a clear picture of the individuals' internal preparations and functional responses.

Wearing Sports Mouthguards to Prevent Oral and Maxillofacial Trauma.

The theme of the academic annual conferences held by the Chinese Stomatological Association from 2021 to 2023 was "Protecting Natural Teeth to Maintain Oral Health" and coincided with the 24th Winter Olympic Games that took place in Beijing in 2022, and thus prevention of oral and maxillofacial trauma once again attracted the attention of stomatological experts and the public. The incidence of oral and maxillofacial trauma caused by sports is around 25% to 34%1-5, and varies based on the type of sport and other factors, such as age, sex and the skill level of the participants. The risk of oral and maxillofacial trauma is extremely high in high-confrontation and high-speed sports, especially for children and adolescents. Wearing sports mouthguards when participating in sport is an effective way to prevent and reduce the incidence of oral and maxillofacial trauma in such sports, and is the simplest and most practical method of doing so. Sports have developed and gained in popularity significantly in China in recent years, but the awareness and use of sports mouthguards are low. Based on the above background, the Chinese Stomatological Association advocates that athletes and sport participants should wear mouthguards in various confrontational and high-speed sports, and calls on dental practitioners and sports-related organisations to actively support the popularisation and application of sports mouthguards to prevent or alleviate oral and maxillofacial trauma and to raise awareness and increase knowledge of methods to protect natural teeth.

Should organized sport characteristics be considered as a strategy for meeting physical activity guidelines in children?

A clearer understanding of the relationships between specific sport context with overall physical activity (PA) and sedentary time (ST) may contribute to the development of more accurate preventive strategies to increase children's engagement in PA. This study aimed to examine how different organized sports contributed to children's daily PA and ST. PA was measured for seven days via accelerometers, in 410 children aged 6-10 years (49.8% boys). Of those, 332 (53.0% boys) were engaged in an organized sport and were further considered for statistical analyses. Parents reported children's sport participation (e.g. which sport, number of times per week, duration). The sports were classified into: indoor vs. outdoor; individuals vs. team; combat vs. individual aesthetic vs. racing vs. invasion. Children's height and weight were objectively collected. Multiple one-way analyses of covariance were used to examine the effects of sport characteristics on PA and ST. A linear regression, adjusted for children's sex, age, body mass index and father's educational level, determined the relationship between being involved in multiple PA and sedentary behaviours with Moderate to Vigorous PA (MVPA) levels. Although engaged in an organized sport, only 30% of the children achieved the PA recommendations. Sport (compared with active commute and active play) was the best contributor to daily MVPA. Outdoor sports (vs. indoor) contributed the most to vigorous PA (VPA) and MVPA. Team sports (vs. individual) were significantly associated with lower ST. Children in combat sports accumulated more VPA and MVPA, while those in racing sports showed a higher ST. Sport participation alone does not guarantee children will reach the PA guidelines, and the type of sport can influence children's PA levels. Gender-stereotypes in sports may prevent girls from achieving their 60 minutes of MVPA daily.

Genotypic and Allelic Distribution of the CD36 rs1761667 Polymorphism in High-Level Moroccan Athletes: A Pilot Study.

Previous studies have shown that variations in the CD36 gene may affect phenotypes associated with fat metabolism as the CD36 protein facilitates the transport of fatty acids to the mitochondria for oxidation. However, no previous study has tested whether variations in the CD36 gene are associated with sports performance. We investigated the genotypic and allelic distribution of the single-nucleotide polymorphism (SNP) rs1761667 in the CD36 gene in elite Moroccan athletes (cyclists and hockey players) in comparison with healthy non-athletes of the same ethnic origin. Forty-three Moroccan elite male athletes (nineteen cyclists and twenty-four field hockey players) belonging to the national teams of their respective sports (athlete group) were compared to twenty-eight healthy, active, male university students (control group). Genotyping of the CD36 rs1761667 (G>A) SNP was performed via polymerase chain reaction (PCR) and Sanger sequencing. A chi-square (χ2) test was used to assess the Hardy-Weinberg equilibrium (HWE) and to compare allele and genotype frequencies in the "athlete" and "control" groups. The genotypic distribution of the CD36 rs1761667 polymorphism was similar in elite athletes (AA: 23.81, AG: 59.52, and GG: 16.67%) and controls (AA: 19.23, AG: 69.23, and GG: 11.54%; χ2 = 0.67, p = 0.71). However, the genotypic distribution of the CD36 rs1761667 polymorphism was different between cyclists (AA: 0.00, AG: 72.22, and GG: 27.78%) and hockey players (AA: 41.67, AG: 50.00, and GG: 8.33%; χ2 = 10.69, p = 0.004). Specifically, the frequency of the AA genotype was significantly lower in cyclists than in hockey players (p = 0.02). In terms of allele frequency, a significant difference was found between cyclists versus field hockey players (χ2 = 7.72, p = 0.005). Additionally, there was a predominance of the recessive model in cyclists over field hockey players (OR: 0.00, 95% CI: 0.00-0.35, p = 0.002). Our study shows a significant difference between cyclists and field hockey players in terms of the genotypic and allelic frequency of the SNP rs1761667 of the CD36 gene. This divergence suggests a probable association between genetic variations in the CD36 gene and the type of sport in elite Moroccan athletes.

Subjective Causes for Failure to Return to Sport After Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis.

While current literature has explored the outcomes of athletes who return to sport (RTS) after anterior cruciate ligament (ACL) injuries, less is known about the outcomes of those who are unsuccessful in returning to sport. To determine the rate of athletes who did not RTS after primary ACL reconstruction (ACLR) and to identify the specific subjective reasons for failure to RTS. A comprehensive search of the PubMed/MEDLINE, Scopus, and Web of Science databases was conducted through April 2021. Eligible studies included those explicitly reporting the rate of failure for RTS after ACLR as well as providing details on reasons for athletes' inability to return; 31 studies met the inclusion criteria. Systematic review and meta-analysis. Level 2 to 4. The reasons for failure to RTS referred to in our study are derived from those established previously in the studies included. Data were collected on the number of athletes, mean age, mean follow-up time, type of sport played, failure to RTS rate, and specific reasons for failure to return. The weighted rate of failure to RTS after ACLR was 25.5% (95% CI, 19.88-31.66). The estimated proportion of psychosocial-related reasons cited for failure to RTS was significantly greater than knee-related reasons for failure RTS (55.4% vs 44.6%, P < 0.01). The most cited reason for failure to RTS was fear of reinjury (33.0%). This study estimates the rate of failure to RTS after ACLR to be 25.5%, with the majority of athletes citing fear of reinjury as the major deterrent for returning to sports. We highlight how factors independent of surgical outcomes may impact an athlete's ability to return to play given that the predominant reason for no RTS after ACLR was unrelated to the knee.

Timelines for Return to Different Sports Types After Eight Cervical Spine Fractures in Recreational and Elite Athletes: A Survey of the Association for Collaborative Spine Research.

Prospective cross-sectional survey. To identify timelines for when athletes may be considered safe to return to varying athletic activities after sustaining cervical spine fractures. While acute management and detection of cervical spine fractures have been areas of comprehensive investigation, insight into timelines for when athletes may return to different athletic activities after sustaining such fractures is limited. A web-based survey was administered to members of the Association for Collaborative Spine Research that consisted of surgeon demographic information and questions asking when athletes (recreational vs elite) with one of 8 cervical fractures would be allowed to return to play noncontact, contact, and collision sports treated nonoperatively or operatively. The third part queried whether the decision to return to sports was influenced by the type of fixation or the presence of radiculopathy. Thirty-three responses were included for analysis. For all 8 cervical spine fractures treated nonoperatively and operatively, significantly longer times to return to sports for athletes playing contact or collision sports compared with recreational and elite athletes playing noncontact sports, respectively (P< 0.05), were felt to be more appropriate. Comparing collision sports with contact sports for recreational and elite athletes, similar times for return to sports for nearly all fractures treated nonoperatively or operatively were noted. In the setting of associated radiculopathy, the most common responses for safe return to play were "when only motor deficits resolve completely" and "when both motor and sensory deficits resolve completely." In this survey of spine surgeons from the Association for Collaborative Spine Research, reasonable timeframes for return to play for athletes with 8 different cervical spine fractures treated nonoperatively or operatively varied based on fracture subtype and level of sporting physicality.

Features of mental states in representatives of different types of sports

The article analyzes the problem of finding psychological properties that determine high sports results in various types of sports activities, far from unequivocal conclusions. The analysis of literary data and the results of one's own research provide grounds for asserting that the endogenous factors of influence on mental states are the properties of nervous processes and temperament, and the exogenous factors of influence can be, in the case of a transactional process, the process of the subject's interaction with the environment. In the structure of the transactional process of a stressful episode, several elements can be distinguished: awareness of the stressor and its assessment; disruption of homeostasis, stress-related emotions and cognitive processes; coping reaction; the result of coping and a new assessment of the situation; personal factors. The analysis of the results of the own research of groups of athletes from various sports provides a basis for asserting that statistically significant differences in indicators of the state of mental tension, as well as reactive and personal anxiety, were not found in athletes - relievers. Research into the study of psychological mechanisms that determine the performance of top-level athletes and their evaluation criteria is considered promising in the future.

Virtuality engineering in esports

Traditional sports and esports benefit from the development of Information and Communications Technologies (ICT), including gaming, 4D image/video processing, augmented reality (AR), virtual reality (VR), machine learning (ML), artificial intelligence (AI), big data, high-performance computing (HPC), and cloud computing. On the fuzzy border between the areas of physical and modified reality, both types of sports can coexist. The hardware layer of esports includes PC, consoles, smartphones, and peripherals used to interface with computers, including sensors and feedback devices. The IT layer of esports includes algorithms required in the development of games, online platforms, and virtual reality. The esports community includes amateur and professional players, spectators, esports organizers, sponsors, and other stakeholders. Esports and gaming research spans throughout law (intellectual rights, insurance, safety, and age restrictions), administration (teams, clubs, organizations, league regulations, and tournaments) biology (medicine, psychology, addiction, training and education) Olympic and non- Olympic disciplines, ethical issues, game producers, finance, gambling, data acquisition and analysis. Our article aims to presents selected research issues of esports in the ICT virtualization layer.

Reinjury Anxiety and Return to Sport After Anterior Cruciate Ligament Reconstruction: A Cluster Analysis and Prospective Study Among 162 Athletes

Background: Recent studies have investigated the effect of psychological factors on return to sport (RTS), but none has tested the existence of psychological profiles linked to reinjury anxiety and its links with RTS and reinjury. Purpose: To assess the effect of different psychological profiles on RTS and reinjury. Study Design: Cohort study; Level of evidence, 2. Methods: The study screened patients who were involved in all types of sports for anterior cruciate ligament (ACL) reconstruction (hamstring and patellar tendon autografts). All participants were included during the RTS phase (90-180 days after ACL reconstruction). Reinjury anxiety, fear of reinjury, kinesiophobia, perceived stress, anxiety, depression, knee confidence, self-esteem, optimism, coping, and pain were measured. Hierarchical cluster analysis (Ward method) and analysis of variance were performed. In the second year after surgery, patients were recontacted by telephone to follow-up. RTS and reinjury were compared by profile type. Results: A total of 162 athletes were initially included, of whom 123 responded regarding RTS and reinjury. Cluster analysis showed a 4-cluster solution (χ2[21] = 428.59; λ = .064; P < .001). Profile 1 (27.8%) was characterized by moderate reinjury anxiety and no depression. Profile 2 (22.8%) was characterized by moderate reinjury anxiety and minor anxious-depressive reaction. Profile 3 (30.9%) was characterized by no reinjury anxiety, no depression, and high confidence. Profile 4 (18.5%) was characterized by high anxiety, high depression, and low confidence. Profile 4 had the lowest self-esteem and optimism scores compared with profile 3 (P < .001). In addition, a higher percentage of men was found in profile 3 as opposed to profile 4 (χ2[3] = 11.35; P < .01). Profile 4 had the highest rate of non-RTS with 54.2% (profile 1: 14.3%, P = .001; profile 2: 25.0%, P = .031; profile 3: 22.2%, P = .011). Finally, patients with profile 3 had a higher risk of reinjury (13.9%) than those with profile 4 (0%) (P = .047), who had an extremely conservative RTS. Conclusion: The different profiles will affect RTS, but also the risk of reinjury exclusively for profiles 3 and 4. Rehabilitation management will probably require all stakeholders to understand psychological profiles of athletes to develop an on-demand rehabilitation plan.

Do changes in the frailty score differ by the type of group sports and exercises participated in? A 3-year longitudinal study

BackgroundOlder adults who engage in group sports and exercises achieve greater health benefits than those who exercise by themselves. The benefits of group participation may vary depending on the type of sports/exercise they engage in. The present study aimed to identify the association between specific sports and exercise types performed in groups and evaluate the longitudinal changes in multidimensional frailty scores among community-dwelling older adults in Japan.MethodsWe used 3-year follow-up data from the Japan Gerontological Evaluation Study and analyzed 33,746 men and 36,799 women aged ≥ 65 years. To elucidate the relationship between participation in 20 types of group sports/exercises in 2016 (baseline) and the change in frailty score (using the Kihon Checklist, KCL) from 2016 to 2019, we performed linear regression analyses through multivariate adjustments for age group, self-rated health, marital status, living alone, occupational status, years of education, alcohol drinking status, smoking status, equivalent income, and disease status using an inverse probability weighting method. P < 0.05 was considered statistically significant.ResultsThe mean change in KCL scores over 3 years was + 0.62 and + 0.61 points in men and women, respectively, implying the degree of frailty worsened. The sports/exercise types that significantly prevented increments in KCL scores for both sexes compared to non-participants were hiking (men: B, − 0.36; women: B, − 0.29), walking (men: B, − 0.26; women: B, − 0.24), tennis (men: B, − 0.23; women: B, − 0.24), ground golf (men: B, − 0.21; women: B, − 0.19), and weight exercises (men: B, − 0.19; women: B, − 0.16).ConclusionParticipation in specific sports and exercise groups offer significant physical and psychological benefits for frailty prevention among older adults in Japan. The results of this study may offer substantive evidence to encourage older adults to participate in group activities for the prevention of multidimensional frailty. It will also help public health stakeholders to decide which type of sports and exercise groups to promote in a community.

Double-Leg and Single-Leg Jump Test Reference Values for Athletes With and Without Anterior Cruciate Ligament Reconstruction Who Play Popular Pivoting Sports, Including Soccer and Basketball: A Scoping Review.

OBJECTIVE: To synthesize and present reference values for double-leg and single-leg jump tests in healthy athletes who play pivoting sports, and athletes with anterior cruciate ligament reconstruction (ACLR) who play pivoting sports. DESIGN: Scoping review. LITERATURE SEARCH: We searched PubMed, the Cochrane Library, MEDLINE, Embase, and Web of Science until April 7, 2023. STUDY SELECTION CRITERIA: We included reference values in 2 different categories: (1) double-leg and/or single-leg jump test outcomes in pivoting-sport athletes with ACLR at a specific time point during rehabilitation, and (2) double-leg and/or single-leg jump test outcomes in healthy pivoting-sport athletes. DATA SYNTHESIS: We performed data synthesis for reference values from double-leg jump tests (squat jump and countermovement jump) and single-leg jump tests (vertical hop, single hop for distance, triple hop for distance, crossover hop for distance, medial triple hop for distance, lateral triple hop for distance, 6-m timed hop, side hop, drop jump, and 10-second repeated hop) that were performed according to a standardized test description. We summarized the data for type of sport, sex, sport participation level, and age group. RESULTS: Of the 27 included studies, nine reported reference values from healthy soccer players, six from healthy basketball players, and eleven from other healthy pivoting-sport athletes. LSI dominant/nondominant (LSI-D/ND) ranged between 97% and 106% for healthy soccer players, and between 99% and 120% for healthy basketball players. Four studies reported reference values from pivoting-sport athletes with ACLR from 7 to 10 months postsurgery. CONCLUSION: This scoping review summarizes double-leg and single-leg jump test reference values for athletes who play common pivoting sports, including soccer and basketball. J Orthop Sports Phys Ther 2024;54(6):1-14. Epub 20 March 2024. doi:10.2519/jospt.2024.12374.

Rational combination of program modules from sports games within the framework of the "New Ukrainian School" concept to optimize the process of physical education in 5th and 6th grades

Building a rational and effective system of physical education in the field of secondary education is extremely important for Ukraine, especially considering the challenges that our country is facing. Given this, the task of developing a system for students' physical education in general secondary education institutions is of primary importance. The aim of this work is to determine a rational, effective, and expedient method of combining individual program modules available in the content of the model physical education curriculum for 5th and 6th grades, in order to organize a high-quality process of students' physical education. To achieve this goal, modules from such game sports as basketball, handball, and volleyball were selected. Additionally, the aim of the work was to determine the nature of students' and their parents' subjective perception of these sports. Understanding this will allow for a more effective organization of the physical education process according to the proposed program. The research methodology includes a theoretical analysis of available scientific literature and a questionnaire method. The scientific novelty of the work lies in improving the process of organizing physical education in general secondary education institutions, in line with the current educational concept "New Ukrainian School". In conclusion, it is stated that the annual physical education program version, which is based on the combination of such program modules as "basketball", "handball", and "volleyball", can be an extremely effective and productive system of physical education for 5th and 6th grade students. It is predicted that the combination of these types of sports will more comprehensively affect the development of various physical and psychomotor skills. Also it will contribute to the general physical and social development of children.

The Physical Benefits of Sports, Basis for Enhanced Sports Program

This study conducts a comprehensive analysis by investigating the impact of sports activities on university students' daily lives and their promotional benefits in public awareness and community events. The findings reveal that students generally perceive positive influences in physical, mental, economic, and value integration domains due to sports activities. In the physical domain, students believe that sports make their daily routines more active, and gym fitness is both enjoyable and beneficial. Regarding mental health, students experience a relaxing feeling, enhanced concentration, and the development of positive values through sports. In the economic domain, students see opportunities, networking skills, and improved job prospects resulting from sports involvement. Analyzing the impact based on gender and age indicates no significant differences in most domains. However, variations exist in sports types, particularly in the mental health domain, where volleyball players show higher scores than football players. Furthermore, the study highlights the positive promotional benefits of sports in public awareness campaigns and fun community events. Students recognize the contribution of sports to health awareness, community engagement, and the attraction of external participants. In conclusion, this research emphasizes the importance of sports activities for the holistic development of university students. Practical recommendations are provided for the planning and promotion of university sports activities based on the study's outcomes.

How Elite Athletes with a Spinal Cord Injury Sweat during Exercise-An Exploratory Study.

Sweat and thermal responses in individuals with spinal cord injury (SCI) are impaired depending on lesion characteristics. This is particularly problematic for athletes and may ultimately lead to reduced performance. This exploratory study investigated the feasibility of field-usable methods to objectively collect data relevant to sweat response in elite athletes with SCI. Differences in sweat response were also evaluated for different athlete characteristics. Measurements were performed during exercise and included core temperature (Tc), heart rate, urine specific gravity, fluid intake, sweat rate, and sweat electrolyte concentration. Differences for sex, lesion level (tetraplegia versus paraplegia), motor impairment (complete versus incomplete), and sport type (endurance versus team/skill) were evaluated. Fifteen athletes (median (Q1-Q3) age, 30 (28-36) years; three females; 11 with complete lesions) were included. Endurance athletes were measured during indoor performance tests (n = 10), whereas team/skill athletes were measured during training sessions (n = 5). In the mixed exercise intensities, the average Tc was 37.7 (37.3-37.8) °C and the average heart rate was 126 (100-146) bpm. Dehydration, defined as a urine specific gravity > 1.020 ng/mL, was prevalent in six athletes before exercise and in five athletes after exercise. The sweat rate was lower in athletes with tetraplegia (p = 0.02) and in team/skill athletes (p = 0.008). Collecting sweat and thermal response data from athletes with SCI in the field is feasible. Given the suboptimal hydration status of many athletes, raising awareness of the importance of hydration seems valuable.

Anxiety in elite athletes, sex and age characteristics and association with sports

Introduction: Long-term anxiety can lead to increased injuries and negatively affect physical performance, but it is also a significant risk factor for the development and progression of cardiovascular diseases. At the same time, participation in certain sports at a professional level is associated with an increased prevalence of risk factors such as excess body weight, dyslipidemia and hypertension. Therefore, the study of anxiety in elite athletes seems to us an urgent task.Objective: to assess the prevalence of anxiety of varying severity among elite athletes permanently residing in the Tyumen region, and to identify possible associations of anxiety indicators with sports, gender and age.Materials and methods: The study involved 141 elite athletes of the Tyumen region (40 (28.4 %) and 101 (71.6 %) female and male, respectively) aged from 14 to 38 years (average age 21.0 ± 4.2). Participants competed in both individual (biathlon and judo, n = 62 (44.0 %)) and team sports (volleyball, hockey, n = 79 (56.0%)). Anxiety (reactive and personal) was assessed using the Spielberger — Hanin questionnaire. To assess the independent relationship of the variables under consideration with anxiety indicators, multivariate analysis was used — multinomial logistic regression.Results: Severe reactive anxiety was found in 21 (15.7 %) athletes, and severe personal anxiety in 26 (19.5 %) athletes. 80 (59.7 %) athletes had moderate reactive anxiety, and 83 (62.4 %) had moderate personal anxiety. When conducting multivariate analysis, independent associations of reactive anxiety with age (OR = 1.25, 95 % CI 1.08–1.45, p = 0.003), types of sports (OR = 0.39, 95 % CI 0.17) were established -0.94, p=0.036) and gender (OR=0.23, 95 % CI 0.06–0.93, p=0.039). Personal anxiety was independently associated with gender (OR = 0.12, 95 % CI 0.02–0.63, p = 0.013) and type of sport (OR = 0.29, 95 % CI 0.11–0.77, p = 0.013).Conclusion: The prevalence of anxiety symptoms among elite athletes was quite high. Moreover, the indicator of reactive anxiety among them was independently and significantly associated with age, types of sports and gender, and the indicator of personal anxiety was associated with gender and types of sports.

Late-stage rehabilitation after anterior cruciate ligament reconstruction: A multicentre randomised controlled trial (PReP)

BackgroundAt the completion of formal rehabilitation after anterior cruciate ligament reconstruction, functional capacity is only restored in a small proportion of affected individuals. Therefore, the end of formal rehabilitation is not the end of functional rehabilitation. ObjectiveTo compare adherence to and effectiveness of a late-stage rehabilitation programme with usual care after anterior cruciate ligament (ACL) reconstruction. MethodsThis prospective, double-blind, multicentre, parallel group, randomised controlled trial, included people aged 18 to 35 years after formal rehabilitation completion (mean [SD] 241 [92] days post-reconstruction). Participants were block-randomised to a 5-month neuromuscular performance intervention (Stop-X group) or usual care (medically prescribed standard physiotherapy, individual formal rehabilitation, home-exercises). All outcomes were measured once/month. Primary outcome was the normalised knee separation distance on landing after drop jump. Baseline-adjusted linear mixed models were calculated. ResultsIn total, 112 participants (Stop-X: 57; Usual care: 55,) were analysed. Initially, mean (SD) intervention frequency (units/week) was higher in the Stop-X than the Usual care group: 2.65 (0.96) versus 2.48 (1.14) units/week in the first and 2.28 (1.02) versus 2.14 (1.31) units/week in the second month. No between-group*time(*baseline)-differences were found for the primary outcome. Between-group*time-effects favoured the Stop-X-group at 2 months (fewer self-reported knee problems during sport, KOOS-SPORT) (estimate = 64.3, 95 % CI 24.4–104.3 for the Stop-X), more confidence to return to sport (ACL-RSI) (62.4, 10.7–114.2), fewer pain-associated knee problems (KOOS-PAIN) (82.8, 36.0–129.6), improved everyday activity abilities (KOOS-ADL) (71.1, 6.4–135.7), and improved limb symmetry index in the front hop for distance at 3 and 4 months (0.34, 0.10–0.57; 0.31, 0.08–0.54). No between-group*time-effects occurred for kinesiophobia, symptom-associated knee problems or balance hops performance. At the end of the intervention, 79 % of the Stop-X and 70 % of the Usual care participants (p < 0.05) had successfully returned to their pre-injury sport type and level. ConclusionsThe Stop-X intervention was slightly superior to usual care as part of late-stage rehabilitation after ACL-reconstruction. The small benefit might justify its use after formal rehabilitation completion.

Enhanced risk of disordered eating in female athletes: Exploring the contribution of sport types and competitive levels

This study examined the frequency of attitudes and behaviours characteristic of eating disorders as well as the self-regulation of eating attitudes in exercising women practicing three types of sport considered as at-risk for disordered eating (artistic, endurance or combat) at recreational or competitive level. The 135 participants were asked to complete the EAT-26, the SREASS (Self-Regulation of Eating Attitudes in Sports Scale) and to self-report their current and ideal weights. General linear models (GLM) showed different main effects of the type of sport on EAT scores (F = 45.27; p < 0.001; η2 = 0.41), continuous SREASS scores (F = 30.25; p < 0.001; η2 = 0.32), but not on the Δ weight values. GLM revealed a significant main effect of the level of sport participation on EAT scores (F = 6.11; p < 0.015; η2 = 0.04) and on Δ weight values (F = 9.37; p = 0.003; η2 = 0.068). No significant effect was found on continuous SREASS scores. There was no evidence of an interaction effect of the type and the level of sport participation on EAT and continuous SREASS scores. But a significant interaction effect was observed for Δ weight values (F = 3.63; p =0.02; η2 = 0.05). The endurance group showed the greatest frequency of disrupted eating attitudes and behaviours compared to the artistic (Mean Difference = 11.87; p < 0.001) and the combat group (Mean Difference = 12.44; p < 0.001). SREASS scores suggested “underregulated” and “overregulated” eating attitudes in participants practicing a combat or an endurance sport.The specific characteristics of each sport may influence DE and regulation of eating attitudes in exercising women. Competitive settings could enhance the likelihood of disordered eating development. Additional research is necessary to identify protective factors and implement preventive measures in vulnerable sports.

The Risk of Eating Disorders in Adolescent Athletes: How We Might Address This Phenomenon?

Eating disorders are psychiatric and behavioral health pathologies of high complexity and different etiology, which can affect age groups, sexes, and ethnicities indistinctly. This study aimed to evaluate the risk of eating disorders and the possible relation with the sports profile of Colombian adolescent athletes. This was an exploratory cross-sectional quantitative study that used an online form designed with a sociodemographic questionnaire and the EAT-26 scale to determine the eating disorder risk of the object population. A total of 354 adolescent athletes participated. There were 182 men and 172 women and the mean age was 15.59 (range: 10-19 years, SD = 1.938). The participants presented a significantly low risk of eating disorders (21.2%) with no differences in prevalence between both sexes. The risk of eating disorder was related to the result of the last competition (p = 0.01), the type of sport (p = 0.032), the years of sports practice (p = 0.004), and the number of training hours a day (p = 0.011). It is relevant to recognize that adolescents and athletes are vulnerable populations regarding eating disorders. In conclusion, adolescent athletes should be the object of special attention to prevent eating disorders and their consequences on health and sports performance.
