Money and Uncertainty of Outcome in Modern Sports Based on the Example of Football

One of the fundamental aspects of professional football is competition, which not only captivates fans but also drives its economic success. Money undeniably plays a significant role in determining sports outcomes, as clubs with larger budgets often possess better players. This article aims to examine the relationship between the market value of football clubs’ squads and their performance in the top 15 European leagues, as per the UEFA ranking. Among these leagues, Manchester City boasts the highest players market value in Europe, estimated at 1,110 million EUR, accounting for a mere 11.21% of the total market value of all English Premier League players. In summary, over the course of the last five seasons, out of 75 possible champions across the analysed leagues, the team with the most expensive squad has emerged victorious on 54 occasions. Consequently, it prompts consideration as to whether any measures should be taken to foster greater balance and to reduce the domination of wealthy teams in national football leagues.

The Roles of Perceived Safety Climate and Innovativeness in the Performance of Sport and Recreation Organizations

The recent COVID-19 pandemic created an unpredictable environment regarding the safety operations of sport and recreation organizations. This study was designed to examine how safety climate and organizational innovativeness could promote preferred organizational behavior outcomes in college campus sport and recreation centers. A total of 227 sport and recreation employees were recruited through the National Intramural and Recreational Sports Association. With the collected data, we employed structural equation modeling to assess the research hypotheses. The results indicated that safety climate and innovativeness positively influenced job engagement, therefore leading to enhanced safety compliance and employee innovativeness, which ultimately resulted in higher levels of organizational performance. Peer safety compliance was also found to be a moderator in the relationship between job engagement and safety compliance. In this study, the authors offer new insights into sport organizational performance by emphasizing safety and innovation.

Effect of Aerobic Strength Training on Physical Fitness and Weight Loss of Female University Students

There is still a growing global trend of physical inactivity despite several research showing the positive effects of exercise on health. Furthermore, the most effective weight-loss or weight-control approach is still up for debate. The literature has proven that suggested aerobic strength training (AST) enhances a variety of physical performance outcomes in sports, which helps to validate the effectiveness of AST on physical fitness and weight reduction. Even though AST is one of the most popular strength training techniques, more research is needed to fully understand how it affects female university students' ability to lose weight and perform physically. The purpose of this study was to test the impact of 8 weeks of aerobic strength exercises in female students for physical fitness and weight loss. The study sample comprised overall female students of the Islamia University of Bahawalpur (Baghdad-ul-jaded Campus). The participants of the study were (n = 30) females with ages between (M = 254.5; SD = 30.58 years) were divided into two groups: The experimental group (EG; n=15), and the control group (CG; n=15). Prior to and after the intervention, participants experienced physical and anthropometric measurements. Data were analyzed by applying descriptive, paired sample t-test, and independent t-test. Only a significant improvement for LHGS (p = 0.05), agility (p = 0.00), flexibility (p = 0.01), skipping (p = 0.01), 30-m SRT (p = 0.00) were found in all physical fitness parameters and participants significantly losing weight for the EG (p<0.05) as compared to the control group. The findings suggest that AST improves female students' physical fitness, and helps to reduce weight.

Playing style of women and men elite table tennis players

ABSTRACT Background: Match and notational analysis are well-recognised methods to collect important information about technical-tactical indicators in racket sports (shot, footwork, ball placement, and outcome). The purpose of this study was to analyse the principal indicators, with a special focus on comparing the playing style of women and men high-level players. Methods: twenty matches played by 40 women, and twenty matches played by 40 men were analysed in slow motion by an expert coach. All the players were in the top 111(W) and 120 (M) positions of the ITTF world ranking; Results: women play more shots/rallies and shots/games compared to men. The most used shots are Top forehand and Serve for both groups. Women also prefer to play backhand block and drive. Conversely, men prefer to counterattack with forehand Top C Top. One step is often used by women, and they also prefer to hit the ball without performing any step. Conversely, men perform crossover and pivot footwork. Serves are generally directed to close-to-the-net areas, and the following shots are typically directed to the backhand corner during the rallies. Conclusions: Women showed a specific distribution of technical indicators with respect to men players, suggesting sex-specific training sessions.

Arthroscopic Bankart with remplissage results in lower rates of recurrent instability with similar range of motion compared to isolated arthroscopic Bankart for anterior glenohumeral instability: Asystematic review and meta-analysis.

The addition of the remplissage procedure to an arthroscopic Bankart procedure has been shown to improve clinical outcomes, yet at the expense of potentially decreasing shoulder range of motion. The purpose of this study was to assess recurrent instability, range of motion, functional outcomesand rates of return to sport outcomes in patients undergoing an isolated arthroscopic Bankart repair compared to those undergoing arthroscopic Bankart repair in addition to the remplissage procedure. According to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines, a search was conducted using threedatabases (MEDLINE/OVID, EMBASEand PubMed). Retrieved studies were screened based on predefined inclusion and exclusion criteria for comparative studies. Data were extracted and meta-analysis performed using a random-effects model. A total of 16 studies (13 level III studies, 2 level II studiesand 1 level I) were included with a total of 507 and 704 patients in the Bankart plus remplissage and isolated Bankart repair groups, respectively. No studies reported glenoid bone loss of >20% with the least percentage of glenoid bone loss reported amongstudies being <1%. There was a significantly increased rate of recurrent dislocations (odds ratio [OR] = 4.22, 95% confidence interval [CI]: 2.380-7.48, p < 0.00001) and revision procedures (OR = 3.36, 95% CI: 1.52-7.41, p = 0.003) in the isolated Bankart repair group compared to the Bankart plus remplissage group. Additionally, there were no significant differences between groups in terms of external rotation at side (n.s.), in abduction (n.s.)or at forward flexion (n.s.) at final follow-up. Furthermore, return to preinjury level of sport favoured the Bankart plus remplissage group (OR = 0.54, 95% CI: 0.35-0.85, p = 0.007). Patients undergoing arthroscopic Bankart plus remplissage for anterior shoulder instability have lower rates of recurrent instability, higher rates of return to sport, and no significant difference in range of motion at final follow-up when compared to an isolated arthroscopic Bankart repair. Further large, prospective studies are needed to further determine which patients and degree of bone loss would benefit most from augmentation with the remplissage procedure. Level III.

Searching for the Effects of Momentum in Tennis and its Applications

In sports, a team or athlete may feel they have momentum, or “power/strength” during a game, but this phenomenon is difficult to measure. Furthermore, it is not clear how various events during a match create or change momentum. This paper presents an approach to quantifying ‘momentum’ by introducing a composite model integrating a Logistic Regression Model and a LASSO-based Sparse ARMAX Model to predict momentum shifts and guide strategic decisions during games. The combined model addresses both static and dynamic aspects of momentum, culminating in a comprehensive prediction of momentum trends. The model’s robustness is evidenced by its high accuracy rates across different tennis matches and gender scenarios (95.6%, 94.9%, and 95.5%). This paper’s findings confirm momentum’s measurable impact on sports outcomes, offering a scientific basis for tactical decision-making.

Ulnar Nerve Decompression With Subcutaneous Transposition

Background: Medial-sided elbow injuries are becoming increasingly common among throwing athletes due to overuse and increased specialization at early ages. High valgus stress and repetitive elbow flexion/extension during throwing not only affects the ligaments and dynamic support of the elbow, but commonly affects the ulnar nerve. Indications: Management of cubital tunnel syndrome is initially rest, therapy, and functional training; however, if conservative measures do not appropriately address the ulnar neuropathy, surgical decompression with subcutaneous transposition is a reliable treatment option. Technique Description: An incision is created over the medial epicondyle. The medial antebrachial cutaneous nerve is identified and protected. The ulnar nerve is identified and tagged with a vessel loop to allow for appropriate handling of the nerve. Decompression of the ulnar nerve begins proximally by spreading the tissues superficial to the ulnar nerve and splitting the fascia overlying it. Then, dissection deep to the nerve is performed. A small strip of the medial intermuscular septum will be used as a sling to hold the nerve securely in the transposed position. This is released proximally and the distal attachment to the medial epicondyle is left in place. Decompression is then continued distally by releasing the superficial fascia over the flexor carpi ulnaris (FCU) and a portion of the deep FCU muscle belly and fascia. The nerve is decompressed circumferentially, while preserving penetrating branches to the FCU as able. Ultimately, the ulnar nerve is decompressed 10 cm proximal and 10 cm distal to the medial epicondyle. The intermuscular septum is then pulled over the nerve, checked for appropriate length, and sutured in place both posterior and anterior to the ulnar nerve. Results: Symptom improvement after decompression and transposition is high (&gt;90%); however, performance outcomes in overhead and throwing athletes is variable, and return to previous or higher level of play ranges from 60% to 90%. Discussion/Conclusion: Ulnar nerve decompression and transposition can reliably address underlying symptoms, but results are mixed for return to sport outcomes in overhead and throwing athletes. Patient Consent Disclosure Statement: The author(s) attests that consent has been obtained from any patient(s) appearing in this publication.

Investigation of effects of Circadian Rhythm in Sport: A bibliometric analysis.

This study conducted a bibliometric analysis of the literature on circadian rhythms and sports to identify research trends, knowledge gaps, and future directions. A total of 301 manuscripts, including 245 articles and 56 reviews, were extracted from the Web of Science Core Collection (WoSCC) database, and the bibliometric analysis was performed using VOSviewer 1.6.16. The analysis revealed a continuous increase in the volume of literature on circadian rhythms and sports over the past 38 years, with a focus on the effects of circadian rhythms on physical performance, sleep quality, and jet lag. The study identified 1107 authors who have contributed to this field, with the highest number of publications from Reilly T, Chtourou H, and Atkinson G. The publications were from 512 institutions in 59 countries/regions, with Liverpool John Moores University, University of Sfax, and Manouba University being the leading institutions. The USA, UK, and Australia had the largest number of publications. The top 3 journals were Chronobiology International, Biological Rhythm Research, and Sports Medicine. Despite the increase in research, there are still several underexplored areas, such as the effects of circadian rhythms on cognitive and emotional processes in sports, the role of individual differences in circadian rhythms on sports outcomes, and the potential applications of circadian interventions for sports performance optimization. Future research should address these gaps to advance our understanding of the complex relationship between circadian rhythms and sports.

The Effects of Marijuana Legalization on NCAA Men's Basketball Recruiting

Over the past two decades, attitudes toward marijuana usage have softened. This shift in sentiment coincided with reduced punishments, decriminalization, and in some states, legalization. We find evidence of unexpected consequences of marijuana legalization. Using difference-in-difference estimation, we show that legalization correlates with recruiting outcomes in NCAA D1 sports. Specifically, legalization appears to improve basketball recruiting outcomes for in-state colleges but hurts recruiting outcomes for football programs. Since collegiate athletics are directly correlated with revenues and may affect the number of general applications that a university receives, our results reveal a channel through which marijuana laws could impact post-secondary education.

Arthroscopic Labral Reconstruction With a Modified Inferior Capsular Shift Allows Return to Sport and Excellent Outcomes in Contact and Noncontact Athletes With Anterior Shoulder Instability at Minimum 5-Year Follow-Up

PurposeTo compare return to sport, functional outcomes, recurrence of instability, and osteoarthritis(OA) between collision/contact and limited/non-contact athletes following arthroscopic labral reconstruction with a modified inferior capsular shift for anterior shoulder instability. MethodsAthletes underwent an arthroscopic labral reconstruction with a modified inferior capsular shift, by the senior author between 1999 and 2017. Inclusion criteria were labral stripping from 12(just beyond the biceps anchor) to 6 o’clock, less than 20% glenoid bone loss, active sports participation, and no prior surgery. Athletes were divided into collision/contact and limited/non-contact groups. Outcome measures, physical examination, and radiographic evaluation were collected at a minimum 5-year follow-up. Re-operations or any subjective laxity were considered failures. Radiographs were analyzed for OA utilizing Samilson-Prieto Radiological Classification. ResultsNinety-two patients underwent arthroscopic labral reconstruction with a modified inferior capsular shift. Sixty-four met the inclusion criteria. Thirty-eight(age=26.0±8.0 years) participated in at least one collision/contact sport, and 26(age=38.0±9.0 years) participated in limited/non-contact sports. Two(5%) collision/contact and 3(12%) limited/non-contact athletes had traumatic re-injury requiring revision surgery. Of the remaining athletes (59/64), minimum 5-year follow-up was obtained on 54(92%) with a mean follow-up of 12±4 years(range 5 to 23 years). All athletes returned to their original sport at the same level. There was no significant difference between collision/contact and limited/non-contact athletes in timing of return to sports (5.2±1.9 and 6.0±3.1 months, respectively; p=0.389). There were no significant differences between groups on any outcomes scores. ConclusionArthroscopic labral reconstruction with a modified inferior capsular shift addressed anterior instability with return to sport for both collision/contact and limited/non-contact athletes with excellent functional and clinical outcomes, full shoulder ROM, and a low prevalence of advanced OA at minimum 5-year follow-up. This modified technique resulted in a low failure rate in both limited/non-contact and collision/contact athletes.

Prisoners' Educational Experiences in Five Different Prison Sports Programmes: A Research Note.

Organized sports programmes offer manifold opportunities for learning and personal development. Prisoners in organized sports programmes could profit from these educational opportunities, which could eventually support their process of reintegration into society. However, research on the educational experiences of imprisoned individuals during organized sports activities is scarce. Using quantitative survey data (N = 568 adult male prisoners) collected within the scope of the Hessian Prison Sports Study in Hesse, Germany, the present study examines educational experiences that are instigated through participation in five different prison sports programmes (fitness, racket, and team sports, running groups, and strength training). The results show that participants reported few educational experiences. The most common experiences reported were learning to exert effort and acquiring health-related knowledge. The findings reveal distinct patterns for specific sports programmes. For instance, team sports more frequently address cooperation skills and fairness. This paper advocates for more attention to the educational potential of sports in prison settings, where sports outcomes should be better aligned with the desired educational outcomes.

The Role of Strength-Related Factors on Psychological Readiness for Return to Sport Following Anterior Cruciate Ligament (ACL) Reconstruction.

Psychological readiness following anterior cruciate ligament reconstruction (ACLR) correlates with different return to sport outcomes. However, the relationship between strength and power and psychological readiness remains unexplored. The aim of this study was to investigate the relationship between anterior cruciate ligament return to sport after injury (ACL-RSI) scores and various hamstrings and quadriceps strength and power variables. Twelve participants (20.7 ± 2.5 years old; 174.2 ± 7.5 cm; 70.2 ± 8.5 kg; 18.2 ± 8.3% of body fat) who had an ACLR nine months or more before the study completed the ACL-RSI questionnaire and isokinetic strength testing of the hamstrings and quadriceps (60°·s-1 and 180°·s-1). Based on ACL-RSI scores, they were divided into "cases" and "controls", deemed not psychologically ready and psychologically ready to return to previous sport performance (PILOS), respectively. The main findings are that quadriceps' and hamstrings' rate of torque development (RTD) and time since surgery were determinants of psychological readiness following ACLR. Furthermore, compared to controls, cases showed significantly lower quadriceps torque at angles close to full knee extension (40 deg and 30 deg from extension). They also showed lower RTD than controls, but no difference in peak torque. These results suggest that physiotherapists should facilitate athletes' return to sport (RTS) by focusing on the restoration of RTD and strength at angles close to full knee extension.

Equine allogeneic tenogenic primed mesenchymal stem cells: A clinical field study in horses suffering from naturally occurring superficial digital flexor tendon and suspensory ligament injuries.

Mesenchymal stem cells are an innovative therapeutic for various equine orthopaedic diseases, including soft tissue injuries. To evaluate the safety and efficacy of tenogenic primed equine allogeneic peripheral blood-derived mesenchymal stem cells (tpMSCs) in horses with naturally occurring superficial digital flexor tendon (SDFT) and suspensory ligament (SL) injuries. Multicentre, blinded, randomised, placebo-controlled clinical trial. One hundred client-owned horses with SDFT and SL injuries were randomised to receive an intralesional tpMSC (66) or saline (34) injection. Clinical and ultrasonographic evaluation was performed before treatment and on Days 56 ± 3 and 112 ± 3 after treatment. Long-term data on re-injury was collected up to 2 years after treatment. Significantly more tpMSC-treated horses achieved improvement in fibre alignment score (FAS) (100% vs. 54.5%, p < 0.001) and echogenicity (97.0% vs. 57.6%, p < 0.001) on Day 112 ± 3, and their lesion size decreased significantly (-27.6 ± 25.91 vs. -4.6 ± 26.64 mm2, p < 0.001) compared to the placebo group. A FAS = 0 was achieved in 65% of tpMSC-treated horses, as compared to 9% of placebo-treated horses at Day 112 ± 3. The attending veterinarians reported no re-injury in 41 of 53 tpMSC and in 2 of 26 saline-treated horses available for long-term follow-up (p < 0.001). As this study consisted of client-owned horses, no samples for histology were collected. Long-term follow-up was only available for a subset of enrolled horses. The intralesional administration of tpMSCs was safe and improved the quality of healing and long-term outcomes in sports horses with naturally occurring SDFT and suspensory injuries.

Moderating Effects of Perceived Fairness between Job Insecurity and Outcomes in Sport during the COVID-19 Pandemic

The COVID-19 pandemic has caused major disruptions throughout the sport and recreation industry. Given the heightened levels of stress and uncertainty brought by the pandemic, the purposes of the current study were to (a) examine the structural relationships among job insecurity, job satisfaction, and turnover intention and (b) test the moderation effect of perceived fairness toward governmental policies and actions during the COVID-19 pandemic among these variables for employees in the sport and recreation industry. The conceptual model, including four latent variables—job insecurity, perception of fairness, job satisfaction, and turnover intention—was developed based on uncertainty management theory. A total of 321 sport and recreation managers in South Korea participated in the online survey. Results of structural equation modeling (SEM) revealed that job insecurity had a partial mediating effect on turnover intention through job satisfaction. The results of the moderated mediation analysis indicated a significant difference for the path from job insecurity to job satisfaction between the group with high fairness perceptions and the group with low fairness perceptions. However, the direction of the effect was contrary to expectations. These results provided an opportunity for empirical examination of the psychological and mental health conditions of sport service employees and relevant implications for governmental policies and actions under conditions of uncertainty, such as the COVID-19 pandemic.

Suture Button Fixation for Lisfranc Injuries: A Systematic Review

Category: Midfoot/Forefoot; Trauma Introduction/Purpose: Lisfranc injuries remain a significant but often misdiagnosed orthopaedic injury. Alongside traditional methods of surgical fixation, including arthrodesis and ORIF with screws, suture button fixation is an emerging technique. While several studies have reviewed the outcomes of Lisfranc injuries utilizing plate, screw, and k-wire constructs for arthrodesis or ORIF, there has yet to be a review of the literature focusing on suture button fixation outcomes of Lisfranc injuries. The purpose of this systematic review is to consolidate studies utilizing suture button fixation for the treatment of Lisfranc injuries. Methods: A comprehensive literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using PubMed, Embase, Web of Science, and Cochrane databases for original, English-language studies observing outcomes of Lisfranc injury until August 19, 2022. This combination search strategy employed the following keywords: ((Lisfranc OR Midfoot OR Tarsometatarsal) AND (Injury OR Instability OR Fracture OR Dislocation)) AND (ORIF OR Fixation OR Reconstruction OR suture* OR button* OR Fiber*). The quality of all included studies in this review was evaluated by a modified Coleman score. Clinical outcomes including pre and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, pre and postoperative Visual Analogue Scale (VAS) for pain, and radiographic outcomes such as diastasis were extracted from the text and figures of each study. Return to sports/duty and time to return as well as postoperative complication diagnoses and complications were also extracted from each article. Results: Of the 10 studies included, there were 186 total patients with an age range of 13-72. In every study, all patients were able to return to sport or activity with a return time averaging from 10.8-55.1 weeks. Postoperative AOFAS scores ranged from 83.5- 97 while VAS ranged from 0.6-2.5. Complications were reported in six studies at a rate of 6.7 % including two cases of diastasis, two cases of paresthesia, one case of button irritation, and one of postoperative degenerative joint disease, with no reported revisions. Conclusion: This study summarizes the current evidence regarding suture button fixation of Lisfranc injuries including return to sport, postoperative diastasis, and patient-reported outcomes. In sum, these studies found that suture button fixation shows high levels of patient-reported outcomes, return to sport, and stable fixation in isolated Lisfranc injuries. This surgical technique is advantageous as it provides a more physiologic reduction across the Lisfranc joint and reduces the need for reoperation including the removal of hardware. Further evidence such as large sample size and high-quality RCT studies is needed to draw a definitive conclusion regarding the best treatment for Lisfranc injuries.

Talonavicular Osteochondral Lesions: Surgical Technique and Clinical Outcomes from the Boston and Amsterdam Perspectives.

The primary purpose of the present study was to assess the patient-reported outcomes, complications, and reoperation rate of patient who underwent surgical treatment for symptomatic osteochondral lesions of the talonavicular joint (TNJ). Patients undergoing surgical treatment for symptomatic osteochondral lesions of the TNJ with a minimum of 12-month follow-up were included. Outcomes included clinical patient-reported outcome measures (PROMs), return to sports and work outcomes, and postoperative complications or reoperations. Medical records were screened by 2 independent reviewers. Patients were contacted by phone and underwent an in-depth interview. Additionally, operative techniques for both arthroscopic and open surgical approaches for treating TNJ osteochondral lesions were described. Retrospective Case Series (Level IV) and Surgical Technique. A total of 7 patients were included with a final follow-up time of 25.4 (SD: 15.2) months follow-up. PROMs were considered satisfactory for 5 out of 7 patients, 6 out of 7 patients returned to any level of sports at a mean of 3.7 (SD: 4.2) months, and 5 out of 6 patients returned to preinjury level of sports at a mean of 14 (SD: 7.5) months. All patients returned to work at an average of 5.4 (SD: 3.6) weeks. No complications or reoperations after index surgery were reported. Surgical treatment of TNJ osteochondral lesions is a feasible procedure that may offer successful clinical, sport, and work outcomes in the majority of patients. Both open and arthroscopic surgical treatments are available and can be considered in a patient-specific treatment plan.

Back in Action: High Return to Pre-Injury Level of Sports after Arthroscopic Bone Marrow Stimulation for Osteochondral Lesions of the First Metatarsophalangeal (MTP-1) Joint.

The primary aim was to assess the return to sports outcomes of patients with symptomatic osteochondral lesions (OCLs) to the first metatarsophalangeal (MTP-1) joint treated by arthroscopic bone marrow stimulation (BMS). Secondary aims were to present patient-reported outcome measures (PROMs) on pain scores as well as surgery-related complications or reoperations to the MTP-1 joint. All patients with MTP-1 OCLs treated by arthroscopic BMS with a minimum follow-up of 12 months were included. Outcomes included return to sports and work outcomes, satisfaction outcomes with the performed treatment, PROMs, as well as postoperative complications and reoperations. Medical records were screened by 2 independent reviewers and patients were contacted by phone to partake in an in-depth interview. Complications, reoperations, and revision surgeries were additionally assessed. Nine patients (median age: 22 years with interquartile range (IQR) 20-29 years) were included with a median follow-up time of 47 (IQR: 23-92) months. Six (86%) out of 7 patients who participated in sports preoperatively returned to sports at any level at a median of 4 (IQR: 2.6-5.8) months. Five patients (71%) returned to pre-injury level of sport and eventually returned to performance at a median of 4 (IQR 2.8-7.5) and 8 (IQR: 4.0-10.5) months, respectively. The median Numeric Rating Scale for pain during walking was 1 (IQR 0-2.5) and all (100%) patients were able to return to work at a median of 4 (IQR: 2-17) weeks. Eighty-nine percent of the patients were very or fairly satisfied with the result of their treatment. No complications, reoperations, or revision surgeries were reported. Arthroscopic BMS for patients with symptomatic OCLs to the MTP-1 joint can be considered safe and yields an 86% return to sport at any level and a 71% return to pre-injury and performance level, with good clinical, return to work, as well as satisfaction outcomes.
