Descriptive statistics and a logistic regression were completed to analyze data.Results: Factors such as education level(p = 0.05) and number of concussions treated(p = 0.05) predicted use of the stepwise progression,whereas sex(p = 0.17), employment setting(p = 0.17), state law(p = 0.86), and years practicing(p = 0.17) did not predict whether ATs were following the stepwise progression.Conclusion: The majority of the ATs from this study are employing the stepwise progression to safely return athletes to play after sustaining a concussion. This demonstrates that ATs are providing a standard of care for concussed athletes across various athletic training settings; however,having a graduate degree and treating more concussions per year are predictors of whether an AT follows all steps of the stepwise progression.展开更多

Methods: Twenty healthy college athletes (male/female, 1/1) consumed 6 grams of dietary fiber (Fiberpro, Taiyo Lab Inc., Tokyo) daily for four weeks and were evaluated for their athletic performance, salivary biomarkers of stress (α-amylase activity pre-post exercise, cortisol, melatonin, and secretory immunoglobulin A (SIgA) levels), and mood/affect using the Profile of Mood State 2nd edition (POMS 2®). Measurements were taken at baseline (before supplementation), at Week 4 (after 4 weeks of supplementation), and at Week 8 (4 weeks after the completion of supplementation). Results: Results showed that athletic performance and exercise-induced elevation in salivary α-amylase activity improved with Fiberpro supplementation in both men and women. Further, the Anger-Hostility scale in POMS was significantly elevated in men;in women, an increase in Vigor-Activity score, a single index of positive mood, was noted. These findings suggest that Fiberpro may induce differential affective responses in men and women. Meanwhile, Fiberpro did not affect the normal diurnal changes in salivary melatonin and SIgA levels, but it appeared to augment the normal circadian patterns of cortisol, an effect that persisted for a month without Fiberpro intake. We propose that boosting fiber intake in young, healthy athletes may improve gut microbiota and confer resilience against stress.展开更多

Athletic Pubalgia is often multifactorial with several pathologies overlapping to cause groin pain. Soft tissue disruptions at the insertions of adductor longus and rectus abdominis to the pubic symphysis are often encountered. Prolotherapy is the method of injecting an irritant solution into a joint space, ligament or tendon insertion site. The solution is thought to induce a regenerative response in the affected area through several mechanisms, including the induction of inflammation and vascular reconfiguration. Research objectives: The use of prolotherapy to treat Athletic Pubalgia has not been reported. The aim of this study was to assess ultrasound-guided prolotherapy as a therapeutic option in the treatment of Athletic Pubalgia. Methods: A case report, with informed consent (human material or human data were performed in accordance with the Declaration of Helsinki), involving a 24-year-old female presenting with Athletic Pubalgia. The patient presented with severe chronic right groin pain sustained while playing camogie. Conservative management options, including rest and rehabilitation with physiotherapy had failed to control this pain. Through dynamic ultrasound scanning, focal lesions were identified in the insertions of rectus abdominis and adductor longus to the pubic symphysis. Prolotherapy with 5% dextrose to the affected areas was performed. Assessment of analgesic and rehabilitation response was planned. Results: A sustained analgesic effect was observed at clinical follow-up at 6 weeks. Patient returned to full sporting activity. Conclusions: Ultrasound-guided prolotherapy has not yet been described as a treatment option in Athletic Pubalgia. In this case report, it was an effective pain-relieving therapy with improved rehabilitation. Larger studies are required to evaluate its efficacy.展开更多

We used the generalized extreme value (GEV) distribution to predict the ultimate 100 m, 200 m, 400 m, 4 × 100 m relay, and long jump records of male gold medalists at the Olympics. The diagnostic plots, which assessed the accuracy of the GEV model, were fitted to all event records, validating the model. The 100 m, 200 m, 400 m, 4 × 100 m, and long jump records had negative shape parameters and calculated upper limits of 9.58 s, 19.18 s, 42.97 s, 36.71 s, and 9.03 m, respectively. The calculated upper limit in the 100 m (9.58 s) was equal to the record of Usain Bolt (August 16, 2009). The 100 m and 200 m world records were close to the calculated upper limits, and achieving the calculated limit was difficult. The 400 m and 4 × 100 m relay world records were almost equal to the calculated upper limits and the 500-year return level estimate, and slight improvement was possible in both. At the Tokyo Olympics in August 2021, in the 100 m, 200 m, and 4 × 100 m, in one year the probability of occurrence for a record was about 1/30. In the 400 m and long jump, it was about 1/20. In the 100 m, 200 m, and 4 × 100 m relay, more difficult records show that a fierce battle has taken place.展开更多

If not managed appropriately, patients may experience recurrent instability, chronic pain, osteochondral lesions of the talus, premature osteoarthritis, and other significantlong-term disability. Certain populations, including young athletes, military personnel and those involved in frequent running, jumping, and cutting motions, are at increased risk. Proposed risk factors include prior ankle sprain, elevated body weight or body mass index, female gender, neuromuscular deficits, postural imbalance, foot/ankle malalignment, and exposure to at-risk athletic activity. Prompt, accurate diagnosis is crucial, and evidence-based, functional rehabilitation regimens have a proven track record in returning active patients to work and sport. When patients fail to improve with physical therapy and external bracing, multiple surgical techniques have been described with reliable results, including both anatomic and nonanatomic reconstructive methods. Anatomic repair of the lateral ligamentous complex remains the gold standard for recurrent ankle instability, and it effectively restores native ankle anatomy and joint kinematics while preserving physiologic ankle and subtalar motion. Further preventative measures may minimize the risk of ankle instability in athletic cohorts, including prophylactic bracing and combined neuromuscular and proprioceptive training programs. These interventions have demonstrated benefit in patients at heightened risk for lateral ankle sprain and allow active cohorts to return to full activity without adversely affecting athletic performance.展开更多

Diagnostic elements, such as etiology, directionality, and degree of instability are essential factors to assess in the unstable athletic shoulder. Concomitant injuries and associated pathologic lesions continue to be a significant challenge in the surgical management of posterior shoulder instability. Return to sport and previous level of play is ultimately the goal for every committed athlete and surgeon, thus subpopulations of athletes should be recognized as distinct entities requiring unique diagnostic, functional outcome measures, and surgical approaches.展开更多

Experimental part of the study has been carried out in the course of training camps and competitions since 2010. Forty Russian national teams in 15 winter and 3 summer Olympic sports participated in the research. Theoretical concepts set forth in the works of Anthony Stafford Beer made a basis of a system of control and management developed for the Russian national winter sports teams. In particular, a five-level system was applied to control athletic training. The authors point out that a system of control over athletic training in elite sport teams should take into account a few important issues： （1） each sport, team and athlete has distinctive features; （2） various aspects of athletic training and their interrelation must be aimed at raising effectiveness of training according to individual training plans; （3） coaches and sport managers must be provided with real-time information necessary for development of long-term and short-term training plans and their timely correction.展开更多

These student athletes work their entire lives academically and athletically to reach the ultimate goal: competing in university athletics. However, when these athletes reach university, they are met with non-stop training, homework, exams, and evolving social lives. We have conducted a study at the University of Evansville evaluating how participation in university athletics may impact mental health status among these student athletes, as well as measuring players’ awareness of accessible mental health resources. Over fifty percent of participants reported experiencing at least one mental health condition while competing in their sport;eighty percent reported having knowledge of the mental health resources available to them on campus, however, nearly thirty percent of those knowledgeable reported not knowing how to access these resources. This has indicated a gap in awareness and utilization of mental health resources among student athletes at the University of Evansville.展开更多

Understanding the<b> </b>changes that occur to the cardiac muscle in athletes is still doubtful whether it is only an adaptation to exercise or a concealed pathological condition. Most of these changes are well documented in apparently healthy heart and characterized by cardiac enlargement with Brady-arrhythmias specially individuals participating in long distance runners with exercise capacity without signs of cardiovascular disease. <b>Methods: </b>The study searched the subclinical myocardial necrosis by comparing<b> </b>two groups of young marathon runners, both groups were chosen from Al Gizera youth center in January 2018. First group included adults above the age of 18 years and ran for 12 km. and the second was under 18 years and ran for about 8 km. Both groups were volunteered for this study. They are monitored carefully with blood pressure, heart rate and respiratory rate and their blood samples were collected pre- and post-race immediately for assessment of cardiac markers NTproBNP, Galectin-3 and cTnI. <b>Results: </b>All cardiac markers were elevated post exercise compared to that achieved in pre-exercise regardless age of athletes. Also, pre-exercise adult results were higher in galectin-3 and cTnI but not in proBNP while there is no difference in the acute response in both groups. These results revealed micro cardiac necrosis due to long run exercise with possible bad prognosis. <b>Conclusions:</b> It is important to develop risk assessment and prediction methods for screening the young athletes and consider the term athletic heart as a subclinical disorder rather than physiological adaptation.</span>展开更多

文摘Acute and chronic lateral ankle instability are common in high-demand patient populations. If not managed appropriately, patients may experience recurrent instability, chronic pain, osteochondral lesions of the talus, premature osteoarthritis, and other significantlong-term disability. Certain populations, including young athletes, military personnel and those involved in frequent running, jumping, and cutting motions, are at increased risk. Proposed risk factors include prior ankle sprain, elevated body weight or body mass index, female gender, neuromuscular deficits, postural imbalance, foot/ankle malalignment, and exposure to at-risk athletic activity. Prompt, accurate diagnosis is crucial, and evidence-based, functional rehabilitation regimens have a proven track record in returning active patients to work and sport. When patients fail to improve with physical therapy and external bracing, multiple surgical techniques have been described with reliable results, including both anatomic and nonanatomic reconstructive methods. Anatomic repair of the lateral ligamentous complex remains the gold standard for recurrent ankle instability, and it effectively restores native ankle anatomy and joint kinematics while preserving physiologic ankle and subtalar motion. Further preventative measures may minimize the risk of ankle instability in athletic cohorts, including prophylactic bracing and combined neuromuscular and proprioceptive training programs. These interventions have demonstrated benefit in patients at heightened risk for lateral ankle sprain and allow active cohorts to return to full activity without adversely affecting athletic performance.
文摘Posterior instability of the shoulder is becoming an increasingly recognized shoulder injury in the athletic population. Diagnostic elements, such as etiology, directionality, and degree of instability are essential factors to assess in the unstable athletic shoulder. Concomitant injuries and associated pathologic lesions continue to be a significant challenge in the surgical management of posterior shoulder instability. Return to sport and previous level of play is ultimately the goal for every committed athlete and surgeon, thus subpopulations of athletes should be recognized as distinct entities requiring unique diagnostic, functional outcome measures, and surgical approaches.

Experimental part of the study has been carried out in the course of training camps and competitions since 2010. Forty Russian national teams in 15 winter and 3 summer Olympic sports participated in the research. Theoretical concepts set forth in the works of Anthony Stafford Beer made a basis of a system of control and management developed for the Russian national winter sports teams. In particular, a five-level system was applied to control athletic training. The authors point out that a system of control over athletic training in elite sport teams should take into account a few important issues： （1） each sport, team and athlete has distinctive features; （2） various aspects of athletic training and their interrelation must be aimed at raising effectiveness of training according to individual training plans; （3） coaches and sport managers must be provided with real-time information necessary for development of long-term and short-term training plans and their timely correction.
文摘In recent years, the NCAA student athlete population in the United States has surpassed 500,000, and is continuing to rise each year [1]. These student athletes work their entire lives academically and athletically to reach the ultimate goal: competing in university athletics. However, when these athletes reach university, they are met with non-stop training, homework, exams, and evolving social lives. We have conducted a study at the University of Evansville evaluating how participation in university athletics may impact mental health status among these student athletes, as well as measuring players’ awareness of accessible mental health resources. Over fifty percent of participants reported experiencing at least one mental health condition while competing in their sport;eighty percent reported having knowledge of the mental health resources available to them on campus, however, nearly thirty percent of those knowledgeable reported not knowing how to access these resources. This has indicated a gap in awareness and utilization of mental health resources among student athletes at the University of Evansville.
文摘<strong>Background: </strong><span style="white-space:normal;font-size:10pt;font-family:;" "="">Physical activity has a cardinal role in preventing and treating cardiovascular diseases. Understanding the<b> </b>changes that occur to the cardiac muscle in athletes is still doubtful whether it is only an adaptation to exercise or a concealed pathological condition. Most of these changes are well documented in apparently healthy heart and characterized by cardiac enlargement with Brady-arrhythmias specially individuals participating in long distance runners with exercise capacity without signs of cardiovascular disease. <b>Methods: </b>The study searched the subclinical myocardial necrosis by comparing<b> </b>two groups of young marathon runners, both groups were chosen from Al Gizera youth center in January 2018. First group included adults above the age of 18 years and ran for 12 km. and the second was under 18 years and ran for about 8 km. Both groups were volunteered for this study. They are monitored carefully with blood pressure, heart rate and respiratory rate and their blood samples were collected pre- and post-race immediately for assessment of cardiac markers NTproBNP, Galectin-3 and cTnI. <b>Results: </b>All cardiac markers were elevated post exercise compared to that achieved in pre-exercise regardless age of athletes. Also, pre-exercise adult results were higher in galectin-3 and cTnI but not in proBNP while there is no difference in the acute response in both groups. These results revealed micro cardiac necrosis due to long run exercise with possible bad prognosis. <b>Conclusions:</b> It is important to develop risk assessment and prediction methods for screening the young athletes and consider the term athletic heart as a subclinical disorder rather than physiological adaptation.</span>
文摘Athletic performance refers to integrating athletes’physical fitness,technical,tactical,psychological abilities,as well as cognitive function,and optimizing training protocols,sport nutrition,and sport recovery to demonstrate comprehensive capacity and achieve specific goals in sports training and competitions.Significant progress has been made in elucidating the mechanisms and efficacy of training interventions,supported by empirical evidence from active and athletic populations.
文摘Background:Although intrinsic risk factors contributing to esophageal food impaction are well established,whether social behavior affects its occurrence has not yet been examined.Methods:We conducted a retrospective review of the gastroenterology endoscopy procedural documentation software for the period of 2001–2012 to identify all patients who presented to our emergency department for esophageal foreign-body removal at the time of national athletic events and holidays associated with dietary indiscretions.Results:We found that adults undergoing emergent esophagogastroduodenoscopy during periods celebrating cultural holidays and national athletic events were more likely to experience esophageal food impaction compared with those undergoing emergent endoscopy during periods not associated with these events(36.8% vs 3.6%;P<0.001):a 10-fold increase.During a national holiday/athletic event period,the most common impacted food item was turkey(50%)followed by chicken(29%)and beef(21%).Conclusions:Esophageal food impaction is more likely to occur on American holidays and national athletic events and is associated with large meals.Patients with intrinsic risk factors should be advised to modify their diet during cultural events associated with tachyphagia and large meals to prevent esophageal food impaction.
文摘Chinese State Councilor Urges Athletes to Strive for Glory at Milan-Cortina Winter Olympics Chinese State Councilor Shen Yiqin called on China's winter Olympic athletes to be better prepared for the Milan-Cortina 2026 Games and strive for glory for their nation.Shen made the remarks on December 24,2025,while meeting with athletes and coaches in their training base in Beijing.
文摘Purpose The aims of this study were to propose an alternative method to assess an optimal performance improvement rate(PIR)that would be used as a tool for coaches and elite athletes willing to reach their personal best,mainly those seeking for national,continental or even world record(WR)in middle-distance events.We further compared the improvement rate of women vs.men of the top-10 ranked athletes in the IAAF running these middle-distance events Method The top 10 athletes in the IAAF ranking of 800 m,1500 m,and 3000 m events for each sex were assessed for their history of race times before achieving their personal record(PR).The difference between PR(‘actual’season)and the best race time in the last season was defined as the 1st season improvement rate(1-SIR),whereas the average improvement rate in the last and preceding seasons was the multi-season improvement rate(M-SIR).1-SIR and M-SIR were calculated for each athlete.Result There were sex differences in the 1500 m with a large effect size(d=−0.746)in 1-SIR(P=0.001)and very large(d=−2.249)in M-SIR(P=0.001).Women improved more than men before the PR/WR achievements in the 800 m and 1500 m events(P=0.001)and had similar improvement rates before performing PR/WR in 3000 m events(P=0.533).Conclusion Women improve more before PR/WR achievement in 800 m and 1500 m races.However,in the 3000 m men and women have similar improvement rates in previous seasons before the PR/WR achievement.
文摘1.Background When searching for the term“muscle power”on Google Scholar,about 3.7 million hits come up in 60 ms,and for the past 3 years,there were approximately 225 yearly peer-reviewed publications dealing with muscle power.Muscle power has been used to assess and predict athletic performance,to determine muscle rehabilitation following injury or disease,to measure functional decline as occurs in aging,and many other topics.
文摘Purpose To measure changes in strength,power,and agility over consecutive seasons based on competition level in figure skaters.Methods A total of 197 competitive singles figure skaters(age range=9-25 years old)completed combines with United States Figure Skating on two consecutive seasons between 2011 and 2018.Skaters either remained in the same competitive on-ice level or increased by one level on consecutive seasons.All athletes completed the hexagon agility test,maximal verti-cal jump,timed tuck jumps,push-ups,and bent knee v-ups.Repeated-measures analyses of variance separated by sex with Tukey’s post hoc were performed for each dependent variable and Cohen’s d effect sizes were calculated for all significant differences.Results Female skaters who remained in the same level demonstrated improved performance on vertical jump(3.66 cm higher),timed tuck jumps(3.77 more jumps),v-ups(1.59 more v-ups),and hexagon jump(1.17 s faster).There was an interaction for female skaters who remained in the same level(P=0.004),with senior and junior levels outperforming inter-mediate level skaters on the hexagon jump test.Female skaters who increased level demonstrated improved performance on the vertical jump(2.24 cm higher),hexagon jump(1.16 cm faster),and tuck jump(3.03 more jumps).Male skaters did not demonstrate any changes in performance except v-ups(2.86 more v-ups)for those who increased level.Conclusions The greatest changes were in lower level female skaters who remained in the same level,supporting the impor-tance of participating in strength and conditioning programs earlier in skating careers to maximize athleticism before reaching the senior level,when changes in off-ice performance plateau.
