Objective.-To compare altitude responses of 2 ultraendurance athletes and 2 nonathletes during a 2-week expedition on Denali (Mount McKinley).. Methods.-The severity of acute mountain sickness (AMS) symptoms (Lake Louise AMS guidelines) and pulmonary function parameters (forced vital capacity, forced expiratory volume in 1 second, peak expiratory flow) as well as resting heart rate and arterial oxygen saturation measurements were taken during the climb. Baseline measurements were made at 375 m, and field tests were performed at altitudes of 2200 m, 2400 m, 3000 m, 3400 m, 4100 m, 4300 m, and 10 m.. Results.-Nonathletes reported moderate AMS symptoms at altitudes up to and including 3000 m, whereas ultraendurance athletes reported moderate AMS symptoms at altitudes above 3000 m. Considerable daily variation existed in pulmonary function measures within and between groups; however, the largest shift from baseline and between groups occurred at 3000 m where ultraendurance athletes had increased and ...
Downloadable! This paper investigates how students collegiate athletic participation affects their subsequent labor market success. It uses newly developed distributional tests to establish that the wage distribution of former college athletes is significantly different from non-athletes and that athletic participation is a significant determinant of wages. Additionally, by using newly developed techniques in nonparametric regression, it shows that on average former college athletes earn a wage premium. However, the premium is not uniform, but skewed so that more than half the athletes actually earn less than non-athletes. Further, the premium is not uniform across occupations. Athletes earn more in the fields of business, military, and manual labor, but surprisingly, athletes are more likely to become high school teachers, which pays a relatively lower wage to athletes. We conclude that nonpecuniary factors play an important role in occupational choice, at least for many former collegiate athletes.
Media release: A new study suggests that head impacts experienced during contact sports such as football and hockey may worsen some college athletes ability to acquire new information. The research is published in the May 16, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study involved college athletes at three Division I schools and compared 214 athletes in contact sports to 45 athletes in non-contact sports such as track, crew and Nordic skiing at the beginning and at the end of their seasons. The contact sport athletes wore special helmets that recorded the acceleration speed and other data at the time of any head impact. The contact sport athletes experienced an average of 469 head impacts during the season. Athletes were not included in the study if they were diagnosed with a concussion during the season. In the study, all of the athletes took tests of thinking and memory skills before and after the season. A total of 45 contact sport ...
Controversy exists as to whether high school, college, and older athletes should undergo mandatory preparticipation ECG to screen for underlying cardiac disease that could predispose to SCD. In general, a higher risk of SCD in an athlete population suggests a greater likelihood that ECG screening would be effective. Previous studies have yielded variable rates of SCD among athletes, with the highest event rates (3.6 per 100,000 athlete-years) reported from the Padua region of Italy prior to a program that instituted mandatory ECG screening. The present results suggest that, among high school athletes in the United States, a uniform preparticipation evaluation that includes history and physical examination, but not ECG, results in a very low rate of SCD, and does not support the use of mandatory ECG screening in this group.. ...
Existing literature focusing on collegiate student-athletes fails to connect early educational experiences and college experiences with sport retirement and later life outcomes. The existing body of work dealing with these issues covers academic success of student-athletes, difficulties with retirement from sport or making the transition from sports participation for athletes in general, and the college to work transition for students separately. College student-athletes are a unique and growing population so expanding the literature about the experiences and outcomes of this population is warranted. The purpose of this work was to better understand how participant characteristics impact the retirement from sport process as well as life outcomes. The sample consisted of N=6,636 former NCAA Division-I student athletes with data from high school, first year of college, and 10 years after their freshman year of college. Demographics and academic abilities were obtained from in high school and ...
There were no ethnic differences between RV parameters in control subjects. Both black athletes and white athletes exhibited greater RV dimensions than control subjects. RV dimensions were marginally smaller in black athletes than in white athletes (proximal outflow tract diameter 30.9 ± 5.5 vs. 32.8 ± 5.3 mm, p < 0.001; longitudinal dimension 86.6 ± 9.5 vs. 89.8 ± 9.6 mm, p < 0.001), although only 2.3% of variation was attributable to ethnicity. RV enlargement compatible with diagnostic criteria for arrhythmogenic RV cardiomyopathy was frequently observed (proximal outflow tract ≥32 mm; 45.0% of black athletes, 58.5% of white athletes). Anterior T-wave inversion was present in 14.3% of black athletes versus 3.7% of white athletes (p < 0.001). Marked RV enlargement with concomitant anterior T-wave inversion was observed in 3.0% of black athletes versus 0.3% of white athletes (p = 0.005). Further investigation did not diagnose arrhythmogenic RV cardiomyopathy in any athlete.. ...
Corrado et al. have published an ESC consensus document on the screening of athletes for competitive sports.[1] Besides a good medical history and examination, a 12 lead ECG is also part of the screening. They have set up special ECG criteria for participants in competitive sports (table 1). If one of the described findings are present on the ECG, the ECG is considered positive and further evaluation is mandatory which can include echocardiography, 24-h ambulatory Holter monitoring, and exercise testing. ECG Features of cardiac diseases detectable at pre-participation screening in young competitive athletes are shown in table 2. Prevalence of ECG abnormalities in competitive athletes has been studied by Pellicia et al.[2](see table below). ECG abnormalities in their study increased with age and level of exercise. In young amateur athletes they found ECG abnormalities in about 7%, a number that rose to 40% in "adult elite athletes". Especially RBBB and left ventricular hypertrophy were often ...

The editorial by Maron (1), as well as the articles by Baggish and colleagues (2) and Wheeler and colleagues (3), have interesting implications regarding the scientific debate about preparticipation cardiovascular screening for athletes. Baggish and colleagues (2) compared a screening protocol with or without 12-lead ECG in a cohort of U.S. collegiate athletes and showed that inclusion of the ECG improved sensitivity for detecting important cardiac abnormalities from 45.5% to 90.9% and altered the negative predictive value of screening from 98.7% to 99.8%. Wheeler and colleagues (3) assessed the costs and survival rates in U.S. athletes who were screened with or without 12-lead ECG and estimated that ECG resulted in 2.1 life-years saved per 1000 athletes screened. The incremental cost-effectiveness ratio of the screening with ECG was $42 000 per life-year saved ...

Morphological cardiac alterations in athletes, commonly known as athletes heart, have been widely described in several cross-sectional echocardiographic studies1-6⇓⇓⇓⇓⇓ that have supported the view that LV remodeling in athletes is a benign phenomenon, representing a physiological adaptation to systematic exercise conditioning. However, the dimensional LV changes observed in some elite athletes may be substantial in absolute terms and unavoidably raise a clinical dilemma and differential diagnosis between athletes heart and structural cardiac diseases, such as HCM or DCM.5,6⇓ These are important medical considerations in that the latter pathologic conditions are frequently responsible for sudden death in young athletes.8,9⇓ Presently, however, there are insufficient data to resolve the uncertainty of whether or not such marked alterations in LV chamber dimensions have potential long-term clinical significance and represent evidence of an incipient pathologic condition.10.

The aim of the study was to examine the lower extremity biomechanics of the stance phase of sprint and endurance athletes, performing maximum velocity sprint runs. The overall purpose of the study was to assist the development of coaching techniques used in the training of endurance and sprint athletes. Twelve specifically trained participants (six sprint & six endurance athletes) were recruited for the study. The participants were asked to run at maximum velocity over a 50m distance for three successful trials. A motion analysis system was used to track all kinematic data from anatomical landmarks identified on the body (MTP, heel, ankle, knee, hip and shoulder joint centres) to form an animated segmental linked system-stick image tracking each trial. A force plate was synchronised with the motion analysis system to obtain kinetic data from a single ground contact. Sprint athletes achieved an 18% increase in horizontal velocity compared to endurance athletes. Differences in stride (lengths, ...

1/4/2017. Athletes in individual sports are more prone to developing depressive symptoms than athletes in team sports, according to a new study.. Our research suggests that depression is particularly high in young athletes, with athletes in individual sports being more vulnerable," says Professor Juergen Beckmann from the Technical University of Munich, who surveyed 162 elite and 199 junior elite athletes in two cross-sectional studies.. Beckmann and his team also conducted a longitudinal study of 85 junior athletes, surveying them three times over the course of a year.. These three studies were complemented by a qualitative study, in which 134 elite athletes were interviewed about perceived causes of their experienced stress, drop-out intentions and depressive symptoms.. The two cross-sectional studies found that sport-specific stress combined with insufficient time for recovery was associated with symptoms of depression. They also found that athletes in individual sports showed significantly ...
To track the long-term outcomes of previous college athletes, the NCAA collaborated with Gallup Inc. to survey those who graduated from 1970-2014. The goal of the study, which included interviews with more than 1,600 former student-athletes ages 22-71, was to evaluate their well-being compared with responding graduates who were not college athletes. The findings showed former college athletes were more likely than non-former college athletes to be thriving in four of the five well-being elements: purpose, social, community and physical. The Gallup study, "Understanding Life Outcomes of Former NCAA Student-Athletes," found the majority of former student-athletes (56 percent) are thriving in the purpose element. Among those who played football or mens basketball, an even higher percentage (62 percent) like what they do each day and are motivated to achieve their goals.. ...
Recent studies investigating ultraendurance athletes showed an association between excessive fluid intake and swelling of the lower limbs such as the feet. To date, this association has been investigated in single-stage ultraendurance races, but not in multistage ultraendurance races. In this case study, we investigated a potential association between fluid intake and feet swelling in a multistage ultraendurance race such as a Deca Iron ultratriathlon with ten Ironman triathlons within 10 consecutive days. A 49-year-old well-experienced ultratriathlete competed in autumn 2013 in the Deca Iron ultratriathlon held in Lonata del Garda, Italy, and finished the race as winner within 129:33 hours:minutes. Changes in body mass (including body fat and lean body mass), foot volume, total body water, and laboratory measurements were assessed. Food and fluid intake during rest and competing were recorded, and energy and fluid turnovers were estimated. During the ten stages, the volume of the feet ...
Professional athletes involved in high-performance sport are at a high injury risk, which may lead to long-term health consequences. Professional athletes often expose themselves to risky behaviours, resulting in a higher acceptance level of occupational risk compared to other occupations. To date, many studies have focused on elite athletes specific injury prevention techniques. The objective of this narrative review is to (1) summarise elite athletes attitudes towards important occupational safety and health (OSH) practices, including injury reporting, medicine usage and personal protective equipment (PPE) usage, and (2) explore factors that may influence elite athletes injury awareness. If injury awareness were given a similar weighting in elite sports as in any other highly physical occupation, the potential benefits to elite athletes and their long-term health could be highly significant. This review identifies that most elite athletes are not aware that sporting injuries are occupational
A new study finds AGT CC genotype is more common in elite power athletes, but not in endurance sports, reports Journal of Strength and Conditioning Research. A specific gene variant is more frequent among elite athletes in power sports, reports a study in the October issue of The Journal of Strength and Conditioning Research, official research journal of the National Strength and Conditioning Association (NSCA). The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.. A "functional polymorphism" of the angiotensiogen (AGT) gene is two to three times more common in elite power athletes, compared to nonathletes or even elite endurance athletes, according to the new research by Paweł Cięszczyk, PhD, of University of Szczecin, Poland, and colleagues. They write, "[T]he M23T variant in the AGT may be one of the genetic markers to investigate when an assessment of predisposition to power sports is made.". Gene Variant More Common in Elite Power ...
IMU Step records movement data through two synchronized sensors placed above the ankle bone. The data is then interpreted through algorithms and software that precisely quantify the impact of each step an athlete takes. Unlike most single-sensor wearables that treat the body as a single unit of mass and only focus on distance, speed and heart rate, IMU Step precisely measures and classifies how hard each limb hits the ground to calculate asymmetries and workout intensity in order to offer an accumulative "bone load" score for each athletes training session. For running-based sports like basketball, where over 40-percent of injuries are sustained on the foot and ankle, these metrics can help coaches and trainers remove the guesswork from a players journey back from a lower limb injury, and dramatically reduce the risk of re-injury.. The analysis of an athletes lower limbs and bone loading impact generated through IMU Step offers a first of its kind look at each athletes body and the impact of ...
Background: Sudden cardiac arrest in a young healthy athlete is a rare but catastrophic event. Current American Heart Association preparticipation screening (AHA PPS) guidelines recommend a focused history and physical without routine imaging or ECG screening. We propose that a focused echocardiogram is a useful modality to identify structural abnormalities that may lead to sudden cardiac arrest or other cardiovascular events in athletes.. Methods: We performed a focused 5 minute echocardiogram on all incoming varsity Division I collegiate athletes at the University of Wisconsin from 2005 to 2013. The echocardiograms were performed on the same day as their routine AHA-based PPS exam. Abnormal findings on a focused echocardiogram prompted further testing for confirmation. In this investigation, we report the prevalence of abnormal findings in these athletes.. Results: Of the 2898 athletes screened, 1484 (51.2%) were female. The average age was 18.8 years. The majority (98.3%) of athletes had ...

Great athletes are an inspiration, and its part of the human experience to idolize them. Average Joes outnumber the professional athletes million(s) to one. Considering this fact, its only natural that we would look up to someone who can do things that we could never do.. I was a 3-season athlete in high school, and there were plenty of athletes whom I looked up to. However, there was always one who inspired me more than the rest. Until recently, that athlete was Lance Armstrong.. Ever since my junior year of high school, when my father won his battle against prostate cancer and I started getting serious about high school sports, Ive held Lance in the highest regard for his strength and ability to overcome any obstacle. But since he was stripped of his seven consecutive Tour De France championship titles, my feelings toward Armstrong and other athletes accused or found guilty of doping have become mixed.. The accusations against Armstrong seem to hold more weight than accusations against ...
9/26/2014. There are many reasons kids play sports-for fun, for the opportunity to be part of a team, to learn how to play a sport, to be physically active, and for some, to help lose or manage weight. On average in the United States, one in three children and teens are overweight. Among young athletes, studies have shown that 26 percent of males and 27 percent of females are overweight.. While being active is always a part of the plan for kids who carry too much weight, there is no guarantee that playing a sport will spur along weight loss.. Several issues exist to complicate and deter weight loss in the sports setting:. The Food Scene: Studies have shown that young athletes eat more, and healthier, than their non-athlete peers. However, if an athlete is not participating in a high energy burning sport, like swimming or soccer, this eating more may cause weight gain. Excess calories eaten by young athletes primarily come from two sources: sweetened beverages like soda, sports drinks and juice ...

The prevalence of dieting and rapid weight loss among athletes in weight-sensitive sports seems to be as common and inappropriate today as it was many years ago.20 Up to 94% of elite athletes competing in weight-sensitive sports report dieting and use of extreme weight control measures to achieve weight target prior to competition.2 Although several studies have reported suboptimal energy and nutrient intake in weight-sensitive sports, the prevalence of athletes with low energy availability (LEA) without ED or DE has not been evaluated.6 This is because of the lack of standardisation related to assessment of LEA. A high prevalence of DE and ED has been reported in female athletes in all of the three groups of weight-sensitive sports described above.4 ,7 For male athletes, the prevalence is higher in gravitational sports, such as ski jumping, other jumping events and endurance-type sports, where excess body weight is associated with a competitive disadvantage.4 ,7 In aesthetic sports, the ...

Mental disorders account for approximately 30% of the non-fatal disease burden in Australia, with the most prevalent disorders of depression, anxiety and substance use disorders experienced by 18% of the population in any single year. These disorders are significantly more common in young adulthood than at any other stage in the lifespan. Despite the availability of effective treatments for many disorders, this high susceptibility in young people is coupled with low rates of seeking professional help. As elite athletes have been found to have less positive attitudes towards seeking help for mental health issues, and they are most often young adults themselves, they may be even less likely than non-athletes to utilise professional services. Although there is a strong relationship between exercise and positive mental health, the prevalence of mental disorders in elite athletes is currently not known. A literature review of the general literature on help seeking and a series of focus groups with ...
A study conducted by the University of Wisconsin School of Medicine and Public Health and funded by the National Federation of State High School Associations (NFHS) Foundation revealed that high school athletes who specialize in a single sport sustain lower-extremity injuries at significantly higher rates than athletes who do not specialize in one sport. The study was conducted throughout the 2015-16 school year at 29 high schools in Wisconsin involving more than 1,500 student-athletes equally divided between male and female participants. The schools involved in the study represented a mixture of rural (14), suburban (12) and urban (3) areas, and enrollments were equally diverse with 10 small schools (less than 500 students), 10 medium schools (501-1,000 students) and nine large schools (more than 1,000 students).. Athletes who specialized in one sport were twice as likely to report previously sustaining a lower-extremity injury while participating in sports (46%) than athletes who did not ...
The purpose of the current study was to explore National Collegiate Athletic Association (NCAA) Division 1 athletes perceptions of mental toughness. Specifically, three areas of mental toughness were explored including attributes, the role of significant others, and strategies used to build mental toughness. In-depth interviews were conducted with 15 athletes from a variety of sports. Lower and higher-order themes were developed to capture the main ideas of mental toughness. Various psychological attributes emerged including performing under pressure, being motivated, being a hard worker, and anticipation. In addition, all athletes referred to coaches as being critical in developing mental toughness (i.e., coaches support, coaches attributes, coaches practices). Creating a positive but tough practice environment emerged as a dominant theme to build mental toughness. In addition, the themes of teaching mental toughness and enhancing athletes psychological skills emerged. Findings offer ...

ABSTRACT. The aim of this study was to examine the perceptions of dry needling within NCAA Division I athletes for muscle performance and/or recovery.Seventy-seven NCAA Division I Athletes completed an 15-item online survey sent via e-mail, which included demographics, exposure to dry needling, and perceptions of effectiveness. Those that had no experience of dry needling were asked to rate their perceptions and reasoning for non-exposure. The results indicated that 66% (n=51) of participants did not have experience with dry needling, while 34% (n=26) did have experience with dry needling. Athletes that experienced dry needling reported that dry needling was effective and comfortable for efficient and speedy recovery. They also reported that they would recommend others to use this recovery treatment. Those athletes with non-exposure to dry needling reported that they would rather use other treatments, concerned with pain or bruising from dry needling or was not sure it would work for recovery. ...

Out of the preliminary findings, two positive tests resulted from more than 10,000 tests conducted by the National Center for Drug Free Sports and the UCLA Olympic Analytical Laboratory. But the laws primary purpose is to prevent our children from turning to steroids by providing a deterrent - the risk of getting caught gives our kids a solid reason to say no.. Consider speed traps on highways. Many adults and teens drive the speed limit not because they know that doing such is safer and saves fuel, but because they know someone is watching - the fear of getting caught is greater than the desire to disobey the law. What happens when you take away the speed traps? People start breaking the law.. Whether the program yielded two positives, 400 positives or 1,000 positives, no one should be drawing conclusions about the extent of steroid use based on these preliminary lab results. The program was never designed to measure steroid use among high school athletes.. According to the statistics from the ...
WEDNESDAY, Nov. 15, 2017 (HealthDay News) -- Young athletes have a very low risk of suffering a fatal cardiac arrest -- and most of those tragic cases probably cannot be predicted, new research suggests.. The study confirms that cardiac arrest is a rare thing among athletes younger than 45. It put the rate at about 0.76 cases per 100,000 competitive athletes each year -- at least in Ontario, Canada.. But more important, researchers found that more than 80 percent of cases probably wont be caught through "pre-participation screening." Such screening is based on the premise that doctors can spot young people with underlying heart abnormalities, keep them out of sports, and thereby save lives.. In Europe, screening includes electrocardiograms (ECGs) to detect electrical abnormalities in the heart, said Dr. Paul Dorian, the senior researcher on the new study. But the value of doing so has been debated for years, said Dorian, a cardiologist at St. Michaels Hospital in Toronto.. For one thing, ECGs ...
Gene doping has the potential to take many difficult-to-detect forms, but officials are focusing on the detection of a single synthetic gene to start. This initial gene doping test will detect whether athletes have received gene therapy with the DNA that encodes erythropoietin (EPO). EPO is a hormone that stimulates red blood cell production, and has the potential to increase blood oxygenation and athletic performance.. According to Carl Johan Sundberg, an exercise physiologist at Karolinska Institute and member of the WADAs gene doping panel, there is currently no evidence that any athletes are participating in gene doping. Based on the increase in the number of athletes found doping as testing methods have improved however, its possible that the arrival of a gene doping test could uncover a whole new way athletes are cheating.. In 2003, WADA added gene doping to its list of banned substances and procedures. In 2006, former German Athletics Association coach Thomas Springstein went on trial ...
Individuals who are involved in explosive sport types, such as 100-m sprints and long jump, have greater bone density, leg muscle size, jumping height and grip strength than individuals involved in long-distance running. INTRODUCTION: The purpose of this study is to examine the relationship between different types of physical activity with bone, lean mass and neuromuscular performance in older individuals. METHODS: We examined short- (n = 50), middle- (n = 19) and long-distance (n = 109) athletes at the 15th European Masters Championships in Poznan, Poland. Dual X-ray absorptiometry was used to measure areal bone mineral density (aBMD) and lean tissue mass. Maximal countermovement jump, multiple one-leg hopping and maximal grip force tests were performed. RESULTS: Short-distance athletes showed significantly higher aBMD at the legs, hip, lumbar spine and trunk compared to long-distance athletes (p ,/= 0.0012). Countermovement jump performance, hop force, grip force, leg lean mass and arm lean ...
Today a large population-based observational study from Italy regarding the potential benefits of screening athletes for their risk of cardiovascular death was published in the Journal of the American Medical Association. This study compiled the incidence of cardiovascular death in athletic and non-athletic individuals between 12 and 35 years of age between 1979 and 2004 in the Veneto region of Italy. After 1982 all participants in competitive sports were required by Italian law to undergo screening for cardiovascular diseases at risk of sudden death during sports. Their evaluation included a family and personal history, physical examination and electrocardiogram (ECG). The findings of the large study demonstrated that there were 55 deaths in the screened athletes compared to 265 deaths in unscreened non-athletes, and the incidence of death decreased from 1 in 27,777 athletes to 1 death in 250,000 athletes over the period studied, an 89% reduction. The presence of an ECG in the screening ...
This formula is very simple. Stride length is the distance an athlete covers with each step. Usually the least amount of strides win the race (a.k.a Usain Bolt). Stride frequency is the amount of strides taken over a given distance or period of time. This is all very simple however, many coaches and parents screw this up royally by trying to verbally cue an athlete to take longer strides and/or quicker steps and this simply results in the athlete taking away from one aspect to give to the other! We dont want to improve stride length by just over striding and reducing frequency. We want to improve stride length by improving traits like mobility and force production.. For example, many taller young athletes have a hard time accelerating over a short distance because moving longer limbs requires more specific strength and coordination than they currently possess. In this situation many coaches will tell the athlete to take shorter choppy steps. All this will do is the screw up his footwork and ...
OVERVIEW. The Athletes Training and Learning to Avoid Steroids Program (ATLAS) is a school-based program designed to lower the use of anabolic steroids among high school athletes. The program combined classroom and weight-training sessions, to teach students about strength training, nutrition, and risk factors for steroid use. Experimental evaluations of the ATLAS program found that the intervention did reduce the use of steroids (though this finding did not hold at the 1 year follow-up) and other illicit drugs, and improved nutrition and exercise behavior and drug refusal skills.. DESCRIPTION OF PROGRAM. Target population: Male school-aged athletic team participants. ATLAS is a 7-week school-based program designed to lower the use of steroids among high school athletes.

Background: Sudden death in young athletes most commonly occurs secondary to previously undiagnosed heart disease, including hypertrophic cardiomyopathy and arrhyth-mogenic right ventricular cardiomyopathy. Preparticipation screenings may be helpful in detecting disease and preventing deaths. In Italy, the preparticipation sports examination includes 12-lead electrocardiography (ECG). This study compared mortality rates from sudden cardiovascular death in screened athletes and an unscreened, nonathlete population.. The Study: The competitive athletes were 12 to 35 years of age, with similarly aged unscreened nonathletes serving as the control group. The study focused on annual incidences of sudden cardiovascular death between 1979 and 2004, and any changes that occurred after the mandatory preparticipation screening program was introduced in 1982. The authors considered three screening periods: prescreening (1979 to 1981), early screening (1982 to 1992), and late screening (1993 to 2004). Sudden ...

Probiotics provide a variety of benefits, especially for digestive health, for everyone who takes these supplements. A new study shows that probiotic supplementation can help boost the immune system in athletes and reduce their risk of upper respiratory tract infections. Weve written about some of these benefits in a past blog, and research continues to support this idea. Scientists have known for years that athletes are at great risk of infection while training for competition. Training schedules, lack of sleep, exhaustive exercise, stress, and travel associated with competition can increase an athletes risk of getting sick. Athletes are eager to…. [Read More…]. ...
