Physical fitness, psychological characteristics, and game performance in youth male soccer players of different levels of competition

ABSTRACT This cross-sectional study examined the differences and associations regarding physical fitness, psychological characteristics, and game performance between elite (n = 64), sub-elite (n = 82), and non-elite (n = 97) youth male soccer players aged 16.2 ± 0.5 years. Physical fitness parameters were assessed using field tests, psychological characteristics were evaluated using validated questionnaires and technical – tactical data were recorded during a competitive soccer match using a multicamera, semiautomatic optical tracking system. Elite players demonstrated superior performance in cardiorespiratory fitness, countermovement jump (CMJ), 10 m sprint, and agility, compared to the sub-elite and the non-elite players. Also, the elite and sub-elite players had faster 40 m sprints than the non-elite players. Game performance was significantly better in the elite group than the other groups and was associated with coping with the adversity and coachability, tension-anxiety, anger-hostility, and fatigue-inertia subscales. Among the physical fitness parameters examined, only agility and CMJ were associated with game performance. In conclusion, elite youth soccer players performed significantly better in various physical fitness and psychological parameters and demonstrated a higher game performance indicator score compared to their sub-elite and non-elite peers. Results suggested that physical fitness and psychological parameters are essential predictors of game performance.

B - 33 A Preliminary Study of the Influence of Thoughts that Prevent Concussion Reporting in Female College Athletes

Abstract Objective To quantify the influence of barriers that prevent intention to report concussions in female athletes. Hypothesis: NCAA Division 1 (D1) athletes will have higher overall reporting barrier scores than Division 3 (D3). Method Participants/Setting: 70 participants started the study and 13 were removed due to incomplete questionnaires, resulting in 57 participants (38 from D1). Athletes participating in contact sports (e.g., soccer) were recruited via email or flyers posted in training rooms. Measurement: A 21-item online questionnaire consisting of eight demographic questions and 13 questions related to barriers that prevent reporting. The barrier items were modified from themes derived from a published qualitative study of 503 collegiate athletes who completed a reporting worksheet. Participants rated agreeability [0 (strongly disagree) to 100 (strongly agree)] for the items that prevent reporting. Results Descriptive statistics indicated barriers likely to prevent reporting (e.g., Losing Playing Time; M = 78.02, SD = 22.61) and those less likely (e.g., Negative Reaction from Teammates; M = 44.75, SD = 31.63). The overall barrier to reporting score was not significantly different between D1 (M = 817.34, SD = 247.90) and D3 (M = 740.11, SD = 225.74), t (55) = 1.141, p = 0.259, d = 0.32. The internal consistency of the 13 barrier items was good, α = 0.852. Conclusions Barriers to reporting with greater saliency were identified, which may need to be prioritized during concussion education. The overall questionnaire score did not significantly differ between D1 and D3 suggesting that barriers operate similarly at different levels of competition. The questionnaire’s good internal consistency suggests it has potential as a research tool.

How Block Dominates Volleyball in Different Levels of Competitions

The present study assessed that in different level (district, state, national international) of Volleyball game or competition how the skills ‘block’ played a dominating role was observed. The videos of semi-final and final game of these four levels were taken 2014-15). These skills were measured by Volleyball Information System (VIS). The result indicated that the block skill of district level was more dominant than international national and state level skill.

Nutritional Status and Cardiometabolic Markers to Determine Athlete’s Achievement: A Cross-Sectional Study

The health, physiological, and nutritional status of an athlete is a top priority in achieving success and career sustainability. Information about an athlete's health, such as blood biochemistry, anthropometry, and adequate nutritional intake, might indicate their ability to perform exceptionally well in different levels of competition. Objective: This research objective is to examine the correlation between athletes' sports achievements in Bandung and their anthropometric traits, nutritional status, and blood biochemical indicators. Methods: This study utilised a cross-sectional design and incidental data collection techniques. Participants: The study comprised 84 athletes from 27 different sports who received achievement allowances from KONI Bandung City. Instruments: n this study, we employed reliable and validated techniques to assess anthropometrics, body composition, somatotype, blood biochemistry, nutritional intake adequacy, and energy adequacy. Data analysis: Both the bivariate and multivariate analyses used logistic regression. Results: The findings of the analysis indicate a significant relationship between athlete performance and two variables: blood pressure (p=0.026) and dietary diversity (p=0.048). The findings from the multivariate analysis revealed a significant relationship between blood pressure and dietary variety, which influences the achievement of athletes. The calculation of the odds ratio (OR) revealed that among all the variables examined, the athlete's blood pressure exhibited strongest correlation with their performance. Conclusion: Blood pressure is a physiological measurement that can serve as an indicator of cardiac function and overall well-being. As a result, it is critical to regularly assess the physical well-being of athletes in Bandung to ensure their consistent optimal performance.

Redefining dominance calculation: Increased competition flattens the dominance hierarchy in dairy cows

Dominance hierarchies are known for mitigating conflicts and guiding priority of access to limited resources in gregarious animals. The dominance hierarchy of dairy cows is typically investigated using agonistic interactions, often monitored at the feed bunk right after fresh feed delivery when competition is high resulting in frequent interactions. Yet, the outcome of agonistic interactions during times of high competition may be more influenced by cows' high valuation of fresh feed than their intrinsic attributes, such that the dominance hierarchy constructed using agonistic interactions under high versus low competition times might differ. We tested how the structure of the dominance hierarchy changes in relation to different levels of competition in a dynamic group of 48 lactating dairy cows over 10 mo, with 6 cows exchanged every 16 d for a total of 159 cows. Using a validated algorithm we continuously detected the actor and reactor of replacement behaviors in 30 feed bins as cows competed for feed. We also calculated the percentage of occupied feed bins to characterize competition at the moment of each replacement. These data were combined to create hierarchies using Elo ratings, separately for 25 occupancy levels ranging from 13% to 100%. For each 1% rise in feeder occupancy, hierarchy steepness fell by 2.41 × 10-3 ± 9.71 × 10-5 (SE), and the percentage of dyads where both cows replaced each other rose by 0.13% ± 0.01%. At the highest feeder occupancy level in comparison to the lowest one, we observed 7.57% more dyads in which the dominant individual (those won more interactions at the lowest feeder occupancy) started to lose proportionally more. The magnitude of decrease in the winning rate of the dominant individual in those dyads also got amplified by 1.06 × 10-3% ± 1.37 × 10-4% (SE) for each 1% increase in feeder occupancy. These findings illustrate how inferred hierarchies vary with competition, with high competition flattening the hierarchy due to increased success of subordinate animals. We suggest that during heightened competition, increased valuation of resources can affect competitive success more than the individual's intrinsic dominance attributes. We recommend against calculating dominance hierarchies based on agonistic interactions during periods of high competition alone, and more generally urge researchers to differentiate agonistic interactions based on context when constructing dominance hierarchies.

Proactive selective attention across competition contexts

Selective attention is a cognitive function that helps filter out unwanted information. Theories such as the biased competition model (Desimone & Duncan, 1995) explain how attentional templates bias processing towards targets in contexts where multiple stimuli compete for resources. However, it is unclear how the anticipation of different levels of competition influences the nature of attentional templates, in a proactive fashion. In this study, we used electroencephalography (EEG) to investigate how the anticipated demands of attentional selection (either high or low stimuli competition contexts) modulate target-specific preparatory brain activity and its relationship with task performance. To do so, participants performed a sex/gender judgment task in a cue-target paradigm where, depending on the block, target and distractor stimuli appeared simultaneously (high competition) or sequentially (low competition). Multivariate Pattern Analysis (MVPA) showed that, in both competition contexts, there was a preactivation of the target category to select, with a ramping-up profile at the end of the preparatory interval. However, cross-classification showed no generalization across competition conditions, suggesting different preparatory formats. Notably, time-frequency analyses showed differences between anticipated competition demands, with higher theta band power for high than low competition, which mediated the impact of subsequent stimuli competition on behavioral performance. Overall, our results show that, whereas preactivation of the internal templates associated with the category to select are engaged in advance in high and low competition contexts, their underlying neural patterns differ. In addition, these codes could not be associated with theta power, suggesting that they reflect different preparatory processes. The implications of these findings are crucial to increase our understanding of the nature of top-down processes across different contexts.

Analyzing the efficiency of the Indian hotel industry using the Malmquist DEA approach

PurposeThe purpose of this paper is to determine the most efficient hotels in the Indian hotel industry, the competitive positioning of these hotels, and the factors that affect their efficiency change.Design/methodology/approachThis study conducts a two-stage analysis and uses data envelopment analysis (DEA) and Global Malmquist productivity index (MPI) approach in the first stage to calculate the managerial performance of a panel of 63 Indian hotels in 2019–2020 and their efficiency change from 2009–2010 to 2019–2020. Bootstrapped generalized least square (GLS) approach is applied in the second stage to evaluate the impact of contextual variables on efficiency change.FindingsUsing the results of the first stage analysis, the authors categorized the 63 Indian hotels into 7 distinct clusters. These clusters represent different levels of competitiveness and pace of growth. The GLS regression reveals a U-shaped relationship between hotel size and efficiency change and a negative relationship between pro social investments and efficiency.Originality/valueThis is the first study in the hotel industry that has used global MPI as a measure of efficiency change in the first stage and GLS in the second stage. In the Indian context, to the best of authors’ knowledge, no such study exists.

Differences between functional movement screen and somatotype to young handball and volleyball players

Introduction. Handball and volleyball are among the world's popular sports, which are played practically in every country at different levels of competition. The aim of this study was to determine the differences in somatotype and morphological characteristics between young handball players and volleyball players as well as the differences in the results of functional body mobility tests between the tested groups. Material and Methods. The research included a sample of 23 female athletes who were divided into two subsamples, as follows. A total of 12 athletes were from the Handball team and a total of 11 athletes were from the Volleyball team. The following anthropometric measurements were conducted: Height and body mass, four skinfolds (triceps, subscapular, supraspinal and calf), breadths (humerus and femur diameters) and girths (arm and calf). Body mass (kg) and body fat (%) of the subjects were measured by the method of bioelectrical impedance (TANITA 545N) with an accuracy of 0.1 kg. Functional Movement Score is a scanning system which includes seven steps (i.e., deep squat, hurdle step, in-line lunge, shoulder mobility, active leg raise, trunk stability push-up, and rotary stability). Results. The results of the study in female handball players recorded a higher percentage of body fat and body mass index compared to female volleyball players (p <.05), while no statistically significant difference was recorded in body weight and height. Analyzing the somatotype of players, it is noticeable that handball players have higher values of endomorphism and mesomorphism, while volleyball players have higher values of ectomorphism. Statistically significant differences were observed in mesomorph and ectomorph (p <.001). In the Functional Movement Screen test, it was noticeable that statistically significant differences were recorded in the two variables (Shoulder mobility and trunk stability push up) in favor of the volleyball players, as well as in the overall standings, while in the other variables no statistically significant difference was recorded. Conclusions. Determining somatotype must occupy the attention of coaches who work with young athletes. Movement-based assessment serves to pinpoint functional deficits (or bio-markers) related to proprioceptive, mobility and stability weaknesses.

Musculoskeletal Injury in American Football: A Bibliometric Analysis of the Most Cited Articles

Background: Textbook knowledge and clinical dogma are often insufficient for effective evidence-based decision making when treating musculoskeletal injuries in American football players, given the variability in presentation and outcomes across different sports and different levels of competition. Key evidence can be drawn directly from high-quality published articles to make the appropriate decisions and recommendations for each athlete’s unique situation. Purpose: To identify and analyze the 50 most cited articles related to football-related musculoskeletal injury to provide an efficient tool in the arsenal of trainees, researchers, and evidence-based practitioners alike. Study Design: Cross-sectional study. Methods: The ISI Web of Science and SCOPUS databases were queried for articles pertaining to musculoskeletal injury in American football. For each of the top 50 most cited articles, bibliometric elements were evaluated: citation count and density, decade of publication, journal, country, multiple publications by the same first author or senior author, article content (topic, injury area), and level of evidence (LOE). Results: The mean ± SD number of citations was 102.76 ± 37.11; the most cited article, with 227 citations, was “Syndesmotic Ankle Sprains” published in 1991 by Boytim et al. Several authors served as a first or senior author on >1 publication, including J.S. Torg (n = 6), J.P. Bradley (n = 4), and J.W. Powell (n = 4). The American Journal of Sports Medicine published the majority of the 50 most cited articles (n = 31). A total of 29 articles discussed lower extremity injuries, while only 4 discussed upper extremity injuries. The majority of the articles (n = 28) had an LOE of 4, with only 1 article having an LOE of 1. The articles with an LOE of 3 had the highest mean citation number (133.67 ± 55.23; F = 4.02; P = .05). Conclusion: The results of this study highlight the need for more prospective research surrounding the management of football-related injury. The low overall number of articles on upper extremity injury (n = 4) also highlights an area for further research.

The Role of the Specific Strength Test in Handball Performance: Exploring Differences across Competitive Levels and Age Groups.

The aim of this study was to determine if specific physical tests are sufficiently discriminant to differentiate players of similar anthropometric characteristics, but of different playing levels. Physical tests were conducted analyzing specific strength, throwing velocity, and running speed tests. Thirty-six male junior handball players (n = 36; age 19.7 ± 1.8 years; 185.6 ± 6.9 cm; 83.1 ± 10.3 kg; 10.6 ± 3.2 years of experience) from two different levels of competition participated in the study: NT = 18 were world top-level elite players, belonging to the Spanish junior men's national team (National Team = NT) and A = 18 players of the same age and anthropometric conditions, who were selected from Spanish third league men's teams (Amateur = A). The results showed significant differences (p < 0.05) between the two groups in all physical tests, except for two-step-test velocity and shoulder internal rotation. We conclude that a battery combining the Specific Performance Test and the Force Development Standing Test is useful in identifying talent and differentiating between elite and sub-elite players. The current findings suggest that running speed tests and throwing tests are essential in selecting players, regardless of age, sex, or type of competition. The results shed light on the factors that differentiate players of different levels and can help coaches in selecting players.

How Does Enterprise Digital Transformation Affect Total Factor Productivity? Based on the Information Intermediary Role of Analysts’ Attention

In the era of Industry 4.0, digital transformation has become an important strategic choice in driving enterprise development. However, there are few studies on how digital transformation affects the total factor productivity of enterprises. In order to fill this theoretical gap, this study explored the impact of digital transformation on total factor productivity from the perspective of information transmission that analysts focus on. Based on data from Chinese A-share listed companies from 2012 to 2021, this work constructed a fixed effects model and a mesomeric effect model. The experimental results show the following: (1) the digital transformation of enterprises significantly improves total factor productivity; (2) the attention of analysts has significantly improved the total factor productivity of enterprises; (3) enterprise digital transformation can significantly improve analysts’ attention, which plays an intermediary role between enterprise digital transformation and total factor productivity; (4) the heterogeneity analysis showed that digital transformation has a more significant promoting effect on the total factor productivity of tertiary industry enterprises and enterprises with lower competitiveness in their respective industries. For the first time, this study explored the mechanism by which digital transformation impacts total factor productivity from the perspective of analysts. It is necessary to encourage enterprises to attach importance to the role of analysts in information transmission in the process of digital transformation. It is suggested that enterprises formulate strategies according to the characteristics of their industries in digital transformation, and the government should formulate differentiation strategies according to the different industries and the different levels of competition between industries in the national economy.

The role of digital transformation practices in the operations improvement in manufacturing firms: A practice-based view

Digitalization has become increasingly crucial for manufacturing firms to optimize their production processes and improve operations management. However, the role of digital transformation practices in firms' operations improvement is still debated in the extant research. Moreover, there is little quantitative research on analyzing their associations using large data sets. Therefore, a theoretical framework is developed in this study based on a practice-based view (PBV) to demonstrate the relationships between digital transformation practices and firms' operational efficiency from three aspects of workforce productivity, physical asset efficiency, and working capital efficiency. Then, the role of industry competition in their relationships is examined. Besides, digital transformation practices are measured using the text analysis method targeting authoritative annual reports to enhance the objectivity and applicability of our quantitative studies. With a large sample of Chinese manufacturing firms from 2016 to 2020, a fixed-effect model is employed to reveal that digital transformation practices have significant and positive impacts on all three aspects of firms’ operational efficiency. It is further observed that industry competition weakens these positive associations. This study enriches the digitalization literature in operations management and expands the application of PBV by verifying the differentiated relationships between digital transformation practices and operational efficiency at different levels of competition. Furthermore, it provides significant practical implications for both managers and policy-makers to appropriately implement and popularize digital transformation practices under an external competitive context.

Is the relationship between bank stability, competition, and intervention quality nonlinear? Evidence from North African countries

AbstractThis paper highlights the existence of a nonlinear relationship between bank stability and competition and analyzes the role that government intervention plays in shaping this relationship. We used a sample of 45 banks in North African countries over the period 2005–2019. We applied a semiparametric approach based on penalized spline estimation. The results unveil the specific shape of the competition–stability relationship at different levels of competition; banks reconsider their risk‐taking behavior at each level of competition. This nonmonotonic stability at different levels of competition is attributed to the quality of intervention, which is found to be an important determinant in shaping this relationship. Thus, we explain the dispersion of risk levels among North African banks in part by the quality of regulation in each country and conclude by recommending the strengthening of regulation, supervision and the macro‐prudential framework.

Countermovement Jump Performance and Team Membership of Youth Female and Male Ice Hockey Players

This study compared the CMJ performance of two teams of young male ice hockey players and two teams of female ice hockey players of different levels of competition and examined whether a specific CMJ variable could predict Prep or Varsity team membership and thus be used as part of the talent identification process for ice hockey. A retrospective analysis of six CMJ variables collected via force platforms was conducted. Independent samples t-tests were used to compare the means of the six CMJ variables between the male teams and female teams and a logistic regression analysis was performed to compare team membership to Prep or Varsity teams with the specific CMJ variables. Significant differences (p &lt; 0.05) were found between Prep and Varsity male players in four CMJ variables, all in favor of the Varsity group: mRSI (p = 0.016, ES = -0.860), peak propulsive power (p = 0.022, ES = -0.811), time to take-off (p = 0.005, ES = 1.008), and braking rate of force development (p = 0.005, ES = -1.025). For the female players, only countermovement depth was significantly different (p = 0.030, ES = 0.841) between Prep and Varsity teams, in favor of the Varsity group. Following the logistic regression analysis, only countermovement depth (Wald's p-value = 0.011) could predict team membership to the Prep or Varsity group for the girls while no CMJ variables could significantly predict team membership to the Prep or Varsity teams for the boys. Results from this study suggest that other CMJ kinetic variables should be used when comparing CMJ performance between athletes rather than only using jump height. In addition, countermovement depth can be used by coaches of female ice hockey players to predict team membership.

Female athlete triad cross-sectional study of soccer players by level of competition.

[Purpose] To determine the actual status of the Female Athlete Triad (low energy availability, menstrual dysfunction, and bone mineral density loss) in soccer players. [Participants and Methods] The survey was conducted between February 1 and March 1, 2022. It included 115 females between the ages of 12 and 28 registered with the Japan Football Association, from teams at different levels. [Results] Players in the top league did not differ in height and weight but were older and had a better understanding of caloric intake. There were no differences in amenorrhea or history of bone fractures based on league. [Conclusion] Of the female soccer players in the four different levels of competition, only the players in the top league had a better understanding of available energy and took preventive measures against the Female Athlete Triad.

Response of marginal height costs and marginal height benefits to competition

Height growth in trees is expensive in terms of the amount of stem tissue required to maintain productive tissue in sunlight. However, shifting allocation from stem support to leader growth and foliage production may allow trees to minimize shading effects on photosynthesis, especially for shorter trees within the population. This hypothesis was evaluated with data collected in competition studies for red alder (Alnus rubra Bong.), Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco), and red pine (Pinus resinosa Ait.). Stem allocation per unit height growth was defined as a marginal height cost, and foliage added per unit height growth was defined as marginal height benefit. A symmetry index was calculated as a simple function of the cumulative relative costs and benefits of the shorter half of trees within plots. Analyses of variance indicated that marginal height costs and benefits significantly increased with age at rates unique to the different levels of competition. It also indicated that marginal height costs were related to the square of initial height at levels also unique to the competition treatments. The effects of competition on the symmetry indexes for marginal height costs and marginal height benefits significantly interacted with age for red alder and Douglas-fir, but not for red pine; for red pine, the indexes only varied with age. The slope between the two indexes was nearly one for all three species, indicating that marginal height costs and benefits change congruently with competition. The results did not support the hypothesis that shorter trees in competing populations change stem allocation to favor foliage growth. The correspondence between the symmetry indexes for marginal height cost and marginal height benefit was apparently due to coordinated development where population effects on how much and where leaf area is added with height growth determine how much stems need to grow to counter the changes in mechanical forces created by the change in crown dimensions. The results provide additional evidence that tree form is the result of coordinated development, not allometry between trees foliage and structural components.

DIFFERENCES IN ACCURACY OF PASSING THE BALL IN YOUNG BASKETBALL PLAYERS OF DIFFERENT LEVELS OF COMPETITION

This research determined the differences in accuracy between junior basketball players at the federal and regional competition level. In this research, the following four tests were used to assess precision: Elevation precision of passing with one hand; Elevation precision of passing with two hands; Shooting a ball that bounces after falling from a height of 3.05 meters directly into the target; Shooting a ball that bounces after falling from a height of 3.05 meters with a mandatory bounce from the ground. No statistically significant differences in accuracy were found between basketball players of the federal and regional level of competition, so hypothesis X1 cannot be accepted.The conclusions reached based on the discussion of the results indicate that the accuracy of passing the ball is not one of the factors that contributes to the difference in quality between basketball players in the junior age who compete in different ranks of the competition. Also, good systematic work in the clubs and good orientation and selection of basketball players in the tested clubs contribute to the quality development of motor skills in general, which do not contribute to differences in basketball players of different levels of competition in younger selections. In further work, it is necessary to further investigate precision as one of the least researched fields of motor skills.

Characterization of differences in sleep behaviors between academy, semi-professional and professional levels of competition in rugby union athletes

Athletes display differing sleep habits to non-athletic populations; similarly, differences occur in sleep habits between athletes from different sports. There is currently limited research investigating the differences in sleep habits and behaviors between different levels of competition within the same sport. A total of 224 rugby union athletes (109 academy, 38 semi-professional, 84 professional) completed the Athlete Sleep Behavior Questionnaire and the Pittsburgh Sleep Quality Index. Professional athletes displayed a significantly longer self-reported sleep duration compared to semi-professional and academy athletes (7 h 52 min ± 51 min vs. 7 h 16 min ± 1 h 15 min vs. 7 h 19 min ± 1 h 12 min, p &lt; 0.01). Pittsburgh Sleep Quality Index global scores revealed a significantly lower ( p = 0.04, d = 0.3) score for professional athletes (5.2 ± 2.5 AU) than academy athletes (6.0 ± 2.7 AU). Individual components of the Pittsburgh Sleep Quality Index revealed significant differences ( p &lt; 0.05) between groups for sleep duration and daytime dysfunction. No significant differences ( p &gt; 0.05) were observed between levels of competition for the Athlete Sleep Behavior Questionnaire global score; however, significant differences ( p &lt; 0.05) were observed for 6 of the 18 items. This study was the first to investigate sleep behaviors across multiple levels of competition in rugby union athletes. Professional athletes displayed longer sleep duration compared to semi-professional and academy level athletes. Additionally, results highlighted that differences exist between levels of competition for specific sleep behaviors. This study identified that sleep behaviors could be improved for all levels of rugby union athletes.

Is Education Beneficial to Environmentally Friendly Behaviors? Evidence from CEOs.

Corporate environmental investment decisions play a crucial role in the protection of the public environment. As the decision-maker and executor, the environmental consciousness and social responsibility of the chief executive officer (CEO) has a long-term impact on the company’s environmental protection strategy, and the CEO’s level of education is a significant factor influencing the CEO’s environmental protection decisions. In this paper, we investigate the extent to which CEO education influences environmental protection investment decisions. A CEO education index is constructed as a proxy for CEO education based on the CEO’s educational background, using a panel sample of Chinese listed firms from 2010 to 2019 and providing robust evidence supporting the notioin that firms with highly educated CEOs are likely to engage in environmental protection spending activities. However, the positive relationship between CEO education and corporate environmental protection investment is reduced when the CEO also holds the position of chairman. The heterogeneity analysis shows that the positive relationship between CEO education and corporate environmental investment behavior is stronger in non-manufacturing and highly monopolistic market competitive industries. Our study contributes to the sustainability literature by providing a new impetus for corporate environmental activities from the perspective of CEO education and sheds light on the impact of the internal and external factors of firms on the investment in environmental protection. It may also help decision makers to decide whether to hire highly educated CEOs and use a dual structure of CEOs in markets with different levels of competition.
