Sexual Minority Athletes Between Concealment and Disclosure: A Multilevel Perspective on Coming Out in Sport

Abstract Introduction Sexual orientation disclosure is a complex, multifaceted process and has not yet been sufficiently explored with regard to LGB + athletes. Methods Based on a multilevel model for understanding sexual minority athletes’ (SMA) experiences in sports, we adopt a mixed-method approach, analysing data from a European survey conducted in 2018 with 1749 LGB + athletes to identify factors that influence the decision of disclosure in sports. Results Multivariate analyses include factors at the macro level (legal situation, population density and gender-typing of sport), meso level (composition of friendships, type of sport and performance level) and micro level (age, sexual orientation, education level and athletic capital). The analysis shows that sexual orientation disclosure is less likely when respondents were younger, had a bisexual or other sexual orientation (compared to lesbian or gay), lower athletic abilities, fewer non-heterosexual friends, participated in individual sports (rather than in team sports) and lived in a country with less inclusive LGB + laws and regulations. Responses to open-ended survey questions highlight the relevance of inclusive sport contexts in terms of trust, safety and LGB + visibility. Conclusions Coming out in sports is influenced by manifold factors on macro, meso and micro levels, and only few of them have gender impact. Policy Implications Policymakers, administrators, coaches, and teammates are relevant stakeholders in sports to establish an environment of trust and safety that eventually leads to an upward spiral of LGB + visibility and the coming out of other SMA.

The flag effect on the physical performance of soccer assistant referees

The aim of the study is to compere the performance of the assistant referee without and with the flag, based on existing and novel tests. Introduction: Millions of fans around the world are invested in the game of soccer, cheering on their favorite team, practicing their skills in the park, or simply watching from afar via the media. As such, fairness in refereeing is of the utmost importance, regardless of the level of game or the teams who are playing. The refereeing team plays a critical role in enforcing the rules of the game and ensuring fair play on the field. In addition to working together in the utmost coordination, the referee, two assistant referees, and the standby official are required to oversee the entire match, while making crucial decisions in split seconds. In addition to their verbal communications, assistant referees must carry and use their flag throughout the game, as means for signally their decisions. When running along the sideline, assistant referees hold the flag in opposite hand to the direction in which they’re moving at that time – resulting in up to 30% of their movements during the game being sideways movements. Testing and comparing the athletic abilities of assistant referees is therefore an essential component in ensuring the accuracy and fairness of soccer matches. Assistant referees play a critical role in enforcing the rules of the game, and their ability to run quickly and accurately while holding a flag can have a significant impact on the outcome of the performance. Participants: 18 assistant referees (two female) who are on the staff of the National League in the Israel Soccer Association. The participants’ mean (±SD) variables were as follows: age=29yrs (±3.4); height=178cm (±0.06); weight=68.22kg (±10.45); fat percent=14.67% (±4.86); and seniority on the league=3.11yrs (±1.45). Results: Show that in all the tests the performance was significant better without the flag (RST, agility test and linear speed), the performance decrement % (RST), show no significant result, P<0.05, t (0.91) = 17. Conclusions: the referee run faster without the flags but the no deferent in the fatigue, so they have to train and testing with flags like in the game.

The Kinematic and Electromyographic Analysis of Roller Skating at Different Speeds on a Treadmill: A Case Study.

Elite athletes in speed roller skates perceive skating to be a more demanding exercise for the groin when compared to other cyclic disciplines, increasing their risk of injury. The objective of this study was to monitor the kinematic and electromyographic parameters of roller speed skaters, linearly, on a treadmill, and to compare different skating speeds, one at 20 km/h and one at 32 km/h, at a 1° inclination. The acquisition was carried out by placing an inertial sensor at the level of the first sacral vertebra, and eight surface electromyographic probes on both lower limbs. The kinematic and electromyographic analysis on the treadmill showed that a higher speed requires more muscle activation, in terms of maximum and average values and co-activation, as it not only increases the intrinsic muscle demand in the district, but also the athlete's ability to coordinate the skating technique. The present study allows us to indicate not only how individual muscle districts are activated during skating on a surface different from the road, but also how different speeds affect the overall district load distributions concerning effective force, which is essential for the physiotherapist and kinesiologist for preventive and conditional purposes, while also considering possible variations in the skating technique in linear advancement.

The Influence of Early Motor Skill Development on Technical Proficiency in Adolescent Football Players

The acquisition of fundamental motor skills (FMS) during early childhood lays the groundwork for more complex motor skills and sports-specific techniques later in life. This study investigates the relationship between early motor skill development and technical proficiency in adolescent football players. A longitudinal study was conducted, tracking the motor skill development of 50 participants from ages 5 to 15. Early motor skills were assessed using standardized tests, while technical proficiency in football was evaluated through a combination of skill-specific drills and match performance analysis during adolescence. The findings revealed a significant positive correlation between early motor skill competence and subsequent technical proficiency in football. Participants who demonstrated higher levels of FMS competence in early childhood exhibited superior ball control, passing accuracy, shooting power, and overall technical performance as adolescent football players. In conclusion, the study underscores the critical role of early motor skill development in shaping technical proficiency in adolescent football players. Promoting and facilitating early FMS acquisition can significantly enhance the technical abilities of young athletes, potentially leading to improved performance and long-term success in football.

A Comparative Analysis of High-Intensity Technique-Specific Intervals and Short Sprint Interval Training in Taekwondo Athletes: Effects on Cardiorespiratory Fitness and Anaerobic Power.

Technique-specific high-intensity interval training (HIITTS) has been proven to be an effective method to enhance the sport-specific bio-motor abilities of taekwondo athletes. However, studies regarding its effects on comprehensive measures of cardiorespiratory fitness are limited. Furthermore, there is a lack of clarity regarding the extent of individual adaptations to this method compared to HIIT in the form of repeated sprints (HIITRS). This study compared the individual adaptations to HIITRS and HIITTS on cardiorespiratory fitness and anaerobic power in trained taekwondo athletes (age = 19.8 ± 1.3 years; body mass = 75.4 ± 9.1 kg; height = 1.73 ± 0.0 .m). All participants completed three sessions per week of a 60-minute regular taekwondo training. Following the 60-minute training, participants completed 3 sets of 10 × 4 s all-out HIITRS or same sets of repeated kicks with both legs (HIITTS) over a 6-week training period. In both groups, rest intervals were set at 15 seconds between efforts and one minute between sets. Before and after the training period, participants underwent a series of lab- and field-based tests to evaluate cardiorespiratory fitness and bio-motor abilities. Both interventions resulted in significant improvements in maximum oxygen uptake (V̇O2max), O2 pulse (V̇O2/HR), first ventilatory threshold (VT1), second ventilatory threshold (VT2), cardiac output (Q̇max), stroke volume (SV), peak power output (PPO), average power output (APO), squat jump (SJ), and countermovement jump (CMJ). However, linear speed (20-m speed time) and taekwondo-specific agility test (TSAT) only responded to HIITRS. HIITRS resulted in greater changes in V̇O2max, V̇O2/HR, VT2, and Q̇max, and higher percentage of responders in measured parameters than HIITTS. In addition, HIITRS elicited lower inter-individual variability (CV) in percent changes from pre- to post-training in all measured variables. These results suggest that incorporating 3 sessions per week of HIITRS into regular taekwondo training results in significantly greater and more homogenized adaptations in cardiorespiratory fitness and bio-motor abilities than HIITTS among trained taekwondo athletes.

Systematic review and meta-analysis on the effect of plyometric vs. resistance training on lower limb explosive power and speed.

This meta-analysis examined the effects of plyometric training (PT) and resistance training (RT) on lower limb explosive power and speed quality in athletes, including lower limb jumping and short-distance sprinting abilities. Empirical studies investigating the PT and RT effect on lower limb explosive power were identified using the PubMed, Web of Science, Embase, EBSOC, and CNKI databases. Heterogeneity testing and potential publication bias assessment were conducted using STATA 15 and Review Manager 5.4. There were 20 articles included, involving 457 participants (230 in the PT group and 227 in the RT group). The meta-analysis results indicated no significant difference in countermovement jump (CMJ) between PT and RT groups (SMD = -1.03; 95% CI = -5.20 - 3.14). Additionally, no significant differences were found between the two training methods for standing long jump (SLJ) (MD = -0.04; 95% CI = 0.00 - 0.09), squat jump (SJ) (MD = -0.79; 95% CI = 1.79 - 0.22), 10-m sprint (MD = -0.02; 95% CI = -0.06 - 0.02), and 30-m sprint (MD = -0.02; 95% CI = -0.15 - 0.11). However, PT and RT comparisons revealed a significant difference between the 5-m sprint (MD = -0.03; 95% CI = -0.05 - 0.00) and the 20-m sprint (MD = -0.05; 95% CI = -0.09 - 0.01). This meta-analysis demonstrated that relative to RT, PT significantly improved the sprinting abilities of athletes at 5-m and 20-m distances. However, no significant differences were observed in sprinting at 10 and 30 meters, CMJ, SLJ, and SJ, indicating consistent effects of PT and RT on jumping performance.

The specific features of the preparation of taekwondo fighters with the consideration of morphofunctional and psychophysiological features of athletes in the initial-training process are revealed. The most important aspects of taekwondo training or contribute to the optimization of the level of training of athletes are identified. Among the various directly the field of psychophysiology of sports is one of the most promising fields for the search for new approaches to the preparation of highly qualified athletes. The same observation of psychophysiological characteristics gives additional information about the functional state of the athlete for different minds of activity. One of the key nutrients is the prediction of potentially high results in a particular sport on the basis of a comprehensive study of mental and mental strengths and anatomical and physiological tasks. The methodology of SAN can be used to monitor the dynamic emotional state of the athlete, reflected in the indicators of self-esteem, activity and mood during the training period. The results of the psychological test revealed the dependence of the indicators of self-esteem, activity and mood on the indicators of physical activity. The effectiveness and efficiency in taekwondo is determined by the demonstration of high agility, the unprecedented strength of the attackers and defenders, the strength of the tactical and emotional fight. Considering that the effectiveness of taekwondo activities depends on the athlete's ability to jump, we analyze the information that is important to understand the psychophysical functions of the control of the athlete's physical position. this correction of the training process.

Cognitive abilities as one of the criteria for the selection and orientation of athletes of various ages in game team sports (for example, football)

Selection in the system of long-term training of athletes is one of the most complex problems in the theory and practice of sports training and involves the development and implementation of scientific and methodological developments in several directions at once: forecasting, modeling and control. As a result, in game team sports and in particular in football, ensuring the effectiveness of the selection and orientation process is determined by a comprehensive assessment of the athlete's abilities, covering all aspects of his preparation. Nowadays, psychodiagnostics and the practical application of the obtained data in the process of selection, competitive activity and in the educational and training process of young football players of various ages are still a reserve that can significantly increase the effectiveness of the training of the sports reserve in football. Not an exception is the study of the cognitive sphere of players, the lack of attention to which leads to a decrease in the prognostic value of conclusions about the potential capabilities of football players, as well as a negative impact on the effectiveness of training in certain areas and, first of all, tactical and technical. In order to determine the level of formation of a number of cognitive abilities of young football players of various ages, appropriate diagnostic measures were carried out, which made it possible to establish the dynamic characteristics of changes in individual cognitive indicators at different stages of training. The two tests used during the diagnosis showed consistent results in determining the age limits, where there is a stabilization of the rate of growth of the studied indicators. The obtained data can be used as criteria for assessing the degree of suitability of a young football player for effective functioning within sports activities at a specific stage of multi-year training.

The Effect of Plant-Based Protein Ingestion on Athletic Ability in Healthy People-A Bayesian Meta-Analysis with Systematic Review of Randomized Controlled Trials.

Plant-based protein supplements are increasingly popular, yet their efficacy in enhancing athletic performance compared to animal protein, insect protein, or other protein types remains under investigation. This study aimed to assess the effectiveness of plant-based protein on athletic abilities such as muscle strength, endurance performance, and muscle protein synthesis (MPS) rate and compare it to no- or low-protein ingestion and non-plant protein sources. Randomized controlled trials (RCTs) evaluating the beneficial and harmful effects of plant-based protein ingestion on athletic ability in healthy individuals were considered. A systematic search of six databases yielded 2152 studies, which were screened using the Covidence systematic review tool. Thirty-one studies were included for meta-analysis after independent selection, data extraction, and risk of bias assessment by two reviewers. The meta-analysis employed a Bayesian approach using the Markov chain Monte Carlo (MCMC) method through a random-effects model. The results demonstrated that plant-based protein supplements provided greater benefits for athletic performance in healthy individuals compared to the no- or low-protein ingestion group [μ(SMD): 0.281, 95% CI: 0.159 to 0.412; heterogeneity τ: 0.18, 95% CI: 0.017 to 0.362]. However, when compared to other types of protein, plant-based protein ingestion was less effective in enhancing athletic ability [μ(SMD): -0.119, 95% CI: -0.209 to -0.028; heterogeneity τ: 0.076, 95% CI: 0.003 to 0.192]. A subgroup analysis indicated significant improvements in muscle strength and endurance performance in both young and older individuals consuming plant-based protein compared to those with no- or low-protein ingestion. Nonetheless, other protein types showed greater benefits in muscle strength compared to plant-based protein [μ(SMD): -0.133, 95% CI: -0.235 to -0.034; heterogeneity τ: 0.086, 95% CI: 0.004 to 0.214]. In conclusion, while plant-based protein ingestion demonstrates superior efficacy compared to low- or no-protein ingestion, it is not as effective as other protein types such as whey, beef, or milk protein in enhancing athletic performance in healthy individuals.

Cardiel-Sánchez, S, Rubio-Peirotén, A, Molina-Molina, A, García-Cebadera Gómez, C, Almenar-Arasanz, A, Ráfales-Perucha, A, Roche-Seruendo, LE, and Cartón-Llorente, A. Effects of plyometric training on running biomechanics and jumping ability of U14 athletes. J Strength Cond Res XX(X): 000-000, 2024-Children under the age of 14 years (U14) are particularly susceptible to musculoskeletal disorders because of growth spurts. Plyometric training has been shown to be beneficial for both injury reduction and performance enhancement. The aim of this study was to evaluate the effects of plyometric training on the jumping ability and running biomechanics of U14 track-and-field athletes. A single-blind randomized controlled trial was conducted. Thirty-five (18 female and 17 male) U14 athletes (age: 12.5 ± 1.2 years; height: 152.3 ± 7.7 cm; body mass: 47.3 ± 6.9 kg) were randomized into experimental and control groups. All subjects completed their usual training for 4 weeks, and those in the intervention group added a low-volume plyometric program twice a week. Preintervention and postintervention assessments included a countermovement jump (CMJ) to determine maximum jump height, 10-second repeated jumps to assess reactive strength index (RSI), and a 3-minute run at 12 km·h-1 to analyze running kinematics contact time, flight time, step length (SL), step frequency (SF), mean power output, vertical spring stiffness, and leg spring stiffness (LSS). The results revealed no main effect of time for any of the variables. A group-by-time interaction was found for RSI (p = 0.045) in the intervention group, whereas a significant increase in LSS was also found after the intervention (p = 0.031). However, no changes in CMJ height or other running parameters were observed. The significance level for the study was set at ρ ≤ 0.05. Plyometric-jump training may improve the stretch-shortening cycle in U14 athletes by increasing RSI and LSS. Athletes and coaches in running-related sports should be aware of these short-term effects when aiming to optimize the energy storage and release mechanism.

Vitamins and minerals are essential for regulating metabolism. According to the nature of sports, athletes can take multi vitamin and mineral supplements to enhance some important metabolic processes and improve sports performance. The purpose of this study is to explore the effects of minerals and vitamins on the sports ability of dance athletes. In this study, 100 professional dancers were randomly divided into the experimental group and the control group by the control variable method. The sports diet and water of the experimental group were supplemented with certain vitamins and minerals. After that, the athletes were trained and tested, including 12 min running, strength test and dance training duration test. The results showed that the 12 min running distance of the experimental group was 420 m more than that of the control group, the balance time was 16 min longer, and the strength was increased by 25 N. In the overall energy comparison, the energy and endurance of the experimental group was two hours more than that of the control group. The conclusion is that minerals and vitamins play a role in promoting and subsidizing the physical fitness of athletes, which are more prominent in endurance and strength. This study provides a certain value for the effect of nutrients on athletes’ ability.

Effects of combining rehabilitation training on the recovery of athletic ability after reconstruction of injured ligament

This paper aims to investigate the impact of conventional rehabilitation training and neuromuscular electrical stimulation (NMES) on the recovery of motor abilities in patients following ligament injury reconstruction. Forty postoperative patients who underwent surgery for anterior cruciate ligament reconstruction (ACLR) were randomly allocated to either the conventional rehabilitation group or the NMES group. The NMES group received NMES treatment in addition to the conventional rehabilitation program starting from eight weeks postoperatively. Various parameters, including knee joint function, stability, and balance, were compared between the two groups at eight weeks and 12 weeks postoperatively. Compared to the data at eight weeks postoperatively, both groups exhibited significant improvements in all measured indicators at 12 weeks postoperatively (p < 0.05). In the 12th week after the surgery, the NMES group demonstrated a Lysholm score of 93.18 ± 3.67 points, an IKDC score of 84.65 ± 2.33 points, a KT-2000 measurement of 0.88 ± 0.45 mm, a thigh circumference difference of −1.33 ± 0.55 cm, a knee flexion angle of 130.12 ± 4.21°, a single-leg standing time of 60.12 ± 9.33 s, a YBT score of 70.26 ± 2.68 points, and a Bulgarian split squat 1RM size of 58.07 ± 6.85 kg; all of these results were significantly superior to those observed in the conventional group (p < 0.05). NMES significantly enhances the recovery of athletic ability in patients following postoperative ACLR and can be effectively applied in clinical practice.

The objectives of this study are to determine whether there is any interaction between agility and athletic performance skills and plyometric training, ladder drill, and agility training; how different these effects are from one another; and how different the effects of low and high agility are from one another. The experimental methodology employed in this work uses a factorial analysis in 2x2. A population of 40 athletes, aged 15 to 17, were selected for the research sample using ordinal pairing. Devices that measure agility using the Illinois Agility Test. The following are the study's findings: The post-test indicates a significant value of p &lt; 0.05, indicating that the plyometric training technique, ladder drill, affects athletic performance skills (p &gt; 0.05). Because the significance value indicates p of 0.006 &lt; 0.05, there is a significant difference between the effects of low and high agility on athletic performance skills (p &lt; 0.05). There is a significant (p &gt; 0.05) interaction between agility (high and low), ladder drill training techniques, and plyometric training methods of athletic performance skills (p &lt; 0.05). The findings indicate that following training, there is a relationship between agility and athletic performance abilities. According to the study, there is a connection between agility (high and low) and athletic performance skills, and agility has a major impact on athletic performance. Training techniques such as plyometric training and ladder drills are also related to agility. Applying the ladder drill and plyometric training techniques affects athletes' performance abilities. It has been demonstrated that doing plyometric and ladder drills may enhance one's athlete's performance ability.

Endurance training for judo athletes: Improving anaerobic and aerobic capacity in the high altitude

Background Problems: Judo is a sport that requires aerobic and anaerobic abilities. This is because the scoring in judo matches is different from other martial arts, where athletes will look for absolute 'ippon' points in one match. Therefore, training is needed that can support increasing aerobic and anaerobic capacity in judo athletes. Endurance training at high altitudes is a training method that is believed to have benefits for athletes' aerobic and aerobic capacity. Research Objectives: The study aims to examine the effect of endurance training on increasing the anaerobic and aerobic capacity of judo athletes based on the Special Judo Fitness Test (SJFT), which is a specific test for the sport of judo that can describe anaerobic and aerobic fitness according to the needs of judo. Methods: This research was conducted in the Puncak area of West Java, which is included in the highlands. An experimental method was used in this research on twenty-four Indonesian elite judo athletes who are carrying out training camps to face the SEA Games in Vietnam in 2021. The t test using SPSS Version 24 was used for data analysis in this study. Findings and Results: The results showed that there was a significant increase in anaerobic and aerobic capacity at high altitudes in judo athletes, as seen from the SJFT. Conclusion: This study concluded that endurance training could increase the anaerobic and aerobic capacity of judo athletes in the highlands. Endurance training at high altitudes for judo athletes is highly recommended because it has been proven to have a significant effect on increasing anaerobic and aerobic capacity. We recommend that judo coaches carry out training at high altitudes because it has been proven to improve the aerobic and anaerobic abilities of judo athletes.
