A pilot study of the attitudes of Australian Rules footballers towards protective headgear.

Despite a relatively high risk of injury to participants of Australian Rules football, very few players report wearing protective equipment. The aim of this paper is to describe the results of a pilot survey of the attitudes of community-level Australian Rules football players towards protective headgear and the risk of head injury. Seventy players from four purposefully chosen clubs in metropolitan Melbourne completed a self-report questionnaire at the end of the 2000-playing season. Almost all players (91.4%) reported they did not wear protective headgear during the 2000 season. Non-headgear users said that headgear was too uncomfortable (47.4%) and they didn't like it (42.1%). However, 80.0% of non-users said they would wear it if it prevented injury. The major motivation for wearing headgear was to prevent injury. Players considered rugby, boxing and driving a car, to be associated with a higher-risk of head injury than Australian Rules football. As a group, the players perceived the risk of head injury in Australian Rules football to be low to moderate when compared to other sports and activities. This partially explains why so few players wore protective headgear. Repeat surveys on a larger sample should be conducted to further understand the attitudes towards protective headgear and perceptions of risk in community-level Australian football players.

A clone of methicillin-resistant Staphylococcus aureus among professional football players.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is an emerging cause of infections outside of health care settings. We investigated an outbreak of abscesses due to MRSA among members of a professional football team and examined the transmission and microbiologic characteristics of the outbreak strain. METHODS: We conducted a retrospective cohort study and nasal-swab survey of 84 St. Louis Rams football players and staff members. S. aureus recovered from wound, nasal, and environmental cultures was analyzed by means of pulsed-field gel electrophoresis (PFGE) and typing for resistance and toxin genes. MRSA from the team was compared with other community isolates and hospital isolates. RESULTS: During the 2003 football season, eight MRSA infections occurred among 5 of the 58 Rams players (9 percent); all of the infections developed at turf-abrasion sites. MRSA infection was significantly associated with the lineman or linebacker position and a higher body-mass index. No MRSA was found in nasal or environmental samples; however, methicillin-susceptible S. aureus was recovered from whirlpools and taping gel and from 35 of the 84 nasal swabs from players and staff members (42 percent). MRSA from a competing football team and from other community clusters and sporadic cases had PFGE patterns that were indistinguishable from those of the Rams' MRSA; all carried the gene for Panton-Valentine leukocidin and the gene complex for staphylococcal-cassette-chromosome mec type IVa resistance (clone USA300-0114). CONCLUSIONS: We describe a highly conserved, community-associated MRSA clone that caused abscesses among professional football players and that was indistinguishable from isolates from various other regions of the United States.

The prevalence of reversible airway obstruction in professional football players.

PURPOSE: To determine the prevalence of reversible airway obstruction in a group of professional football training camp participants. METHODS: All attendees at a Canadian Football League team rookie preseason training camp were invited to participate in a protocol designed to elicit symptoms and signs of reversible airway obstruction (asthma) during the initial preparticipation examination. Those agreeing to the protocol completed a questionnaire containing standardized inquiries about a past history of asthma and the presence of symptoms. Participants then underwent spirometry testing to determine lung function before and after receiving a standardized dose of bronchodilator medication. Players showing evidence of airway obstruction during initial testing and still on the team roster underwent repeat spirometry testing and formal pulmonary function testing during the football season. The follow-up pulmonary function tests were performed to determine those that might benefit from treatment for asthma. RESULTS: Nineteen of 34 (56%) players agreeing to participate had significant reversible airway obstruction as defined by a 12% or greater reversibility in forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEFR), and/or forced expiratory flow rate between 25 and 75% of forced vital capacity (FEF 25-75). In most participants, the diagnosis was made on the basis of spirometry alone. Of those testing positive during initial inquiry, 88% remained positive on repeat spirometry, and 73% had reversible airway obstruction during more stringently controlled hospital-based pulmonary function testing. Those players treated for previously undiagnosed asthma noted an improvement in subjective athletic performance during the football season. CONCLUSION: Based on the remarkably high prevalence of undiagnosed asthma in this group, it may prove worthwhile to test elite football players using lung function parameters.

Catastrophic football injuries: 1977-1998.

The primary purpose of this study was to investigate the occurrence of catastrophic football head and spine injuries, in an attempt to reduce their frequency. We analyzed epidemiological and medical data from 1977 through 1998. Catastrophic football injuries are defined as football injuries that result in death, brain or spinal cord injury, or cranial or spinal fracture. All studied cord injuries involved the cervical region. During the period covered by this study, 118 athletes died as a direct result of participation in the skills of football, 200 football players received a permanent cervical cord injury, and 66 sustained a permanent cerebral injury. Most cervical injuries occurred to defensive players during the act of tackling. The axial loading mechanism of spinal cord injury was identified in 27% of tackling injuries. To further reduce catastrophic injuries, players must stop tackling with the head down and using the head as a battering ram; instead, players should use the shoulder for blocking and tackling. Other recommendations for reducing catastrophic injuries are presented.

On-field management of potential cervical spine injury in helmeted football players: leave the helmet on!

OBJECTIVE: Improper handling of an unstable neck injury in the prehospital setting may result in potential iatrogenically induced neurologic injury. On-site management of the neck-injured, helmeted football player differs from that of other traumatic cervical spine injuries. Controversy still exists regarding helmet removal protocols for stabilizing the cervical spine of helmeted football players with a suspected neck injury. This article provides a critical review of the scientific evidence on cervical spine management in helmeted football players with a suspected cervical spine injury. DATA SOURCES: A computerized literature search of databases (MEDLINE, Sportdiscus) and a manual search of journals from the sports medicine, emergency medicine, orthopedic, and athletic training literature identified articles related to the topic. Additional references were reviewed from the bibliographies of the retrieved articles. STUDY SELECTION: Conclusions are based on five quasi-experimental study designs evaluating motorcycle, football, and hockey helmet removal. In addition, an attempt was made to correlate articles relating to airway and cervical spine management in general trauma to the helmeted athlete. MAIN RESULTS: Several studies support the recommendation not to remove the helmet or shoulder pads in the prehospital setting unless absolutely necessary. If necessary, both helmet and shoulder pads should be removed together as a unit. There are neither published studies in support of helmet removal nor any case reports of increased morbidity to athletes because of failure to remove the helmet in the prehospital setting. CONCLUSIONS: Although studies support the notion that iatrogenic neurologic deterioration may occur with improper handling and attempted removal of the helmet in the prehospital setting, there is no literature to support increased morbidity associated with not removing helmet and shoulder pads. Stabilization of the cervical spine in an injured football player does not require routine prehospital removal of the helmet and shoulder pads before transport.

An evaluation of head movement in backboard-immobilized helmeted football, lacrosse, and ice hockey players.

OBJECTIVE: Improper handling of an unstable neck injury in the prehospital setting may result in iatrogenically induced neurologic injury. Due to helmet design, stabilization of the cervical spine in American football does not require routine removal of the helmet and shoulder pads prior to transport. Adequate data is not available evaluating hockey and lacrosse helmets. This study compares the amount of head movement in American football, lacrosse, and ice hockey helmets during head and neck stabilization procedures. STUDY DESIGN: Prospective. PARTICIPANTS: 12 ice hockey, 9 football, and 9 lacrosse athletes from an National Collegiate Athletic Association Division 1 program. SETTING: On-campus biomechanical laboratory with three HiRes cameras, routinely tested for accuracy. METHODS: Athletes were immobilized on backboards as per protocol. Three motion analysis HiRes cameras follow retroreflective markers placed on the helmet and bite mouthplate to measure relative head and helmet motion. MAIN OUTCOME MEASURES: Helical angles determine the relative range of motion of the head inside the helmets. RESULTS: The mean range of head motion for football players was 4.88 degrees (n = 9, SD 2.07), lacrosse players 6.56 degrees (n = 9, SD 1.61), and ice hockey players 5.54 degrees (n = 12, SD 1.19). These results were not significantly different (p > 0.05). CONCLUSIONS: The rotational head motion seen inside standard immobilized lacrosse and ice hockey helmets is similar to that seen in football helmets. This supports the safety of prehospital stabilization of the potential cervical spine-injured ice hockey and lacrosse athletes with in-line stabilization and helmet in place. Extrapolation of data may not be applicable to other helmet designs, and future studies are needed to determine the safety of emergency procedures in all helmet designs.

Unreported concussion in high school football players: implications for prevention.

OBJECTIVE: To investigate the frequency of unreported concussion and estimate more accurately the overall rate of concussion in high school football players. DESIGN: Retrospective, confidential survey completed by all subjects at the end of the football season. SETTING AND PARTICIPANTS: A total of 1,532 varsity football players from 20 high schools in the Milwaukee, Wisconsin, area were surveyed. MAIN OUTCOME MEASUREMENTS: The structured survey assessed (1) number of concussions before the current season, (2) number of concussions sustained during the current season, (3) whether concussion during the current season was reported, (4) to whom concussion was reported, and (5) reasons for not reporting concussion. RESULTS: Of respondents, 29.9% reported a previous history of concussion, and 15.3% reported sustaining a concussion during the current football season; of those, 47.3% reported their injury. Concussions were reported most frequently to a certified athletic trainer (76.7% of reported injuries). The most common reasons for concussion not being reported included a player not thinking the injury was serious enough to warrant medical attention (66.4% of unreported injuries), motivation not to be withheld from competition (41.0%), and lack of awareness of probable concussion (36.1%). CONCLUSIONS: These findings reflect a higher prevalence of concussion in high school football players than previously reported in the literature. The ultimate concern associated with unreported concussion is an athlete's increased risk of cumulative or catastrophic effects from recurrent injury. Future prevention initiatives should focus on education to improve athlete awareness of the signs of concussion and potential risks of unreported injury.

Community football players' attitudes towards protective equipment--a pre-season measure.

BACKGROUND: The Australian football injury prevention project (AFIPP) was a randomised controlled trial examining the effects of protective equipment on injury rates in Australian Football. OBJECTIVE: To present the results of the AFIPP baseline survey of community football players' attitudes towards protective equipment. METHODS: Teams of players were recruited from the largest community football league in Victoria, Australia, during the 2001 playing season; 301 players were enrolled in the study and all were surveyed before the season began about their attitudes towards protective headgear and mouthguards. RESULTS: Almost three quarters of the players (73.6%) reported wearing mouthguards during the previous playing season (year 2000) compared with only 2.1% wearing headgear. The most common reasons for not wearing headgear and mouthguards (in non-users) were: "I don't like wearing it" (headgear: 44.8%; mouthguards: 30.6%), and "It is too uncomfortable" (headgear: 40.7%; mouthguards: 45.8%). CONCLUSIONS: The higher mouthguard usage reflects the favourable attitudes towards mouthguards by Australian football players generally. Similarly, the low headgear usage reflects the low acceptance of this form of protection in this sport. Further research should be directed towards establishing the reasons why players seem to believe that headgear plays a role in injury prevention yet few wear it.

Ex-professional association footballers have an increased prevalence of osteoarthritis of the hip compared with age matched controls despite not having sustained notable hip injuries.

OBJECTIVE: To compare the prevalence of self reported, physician diagnosed osteoarthritis (OA) of the hip in ex-professional footballers with that in age matched controls in the general public. METHOD: A questionnaire was sent to the 92 football league and premiership managers to assess the prevalence of OA of various joints. The prevalence of OA of the hip in those managers that were ex-professional footballers was assessed. Radiographic controls were obtained and used to assess the prevalence of OA of the hip in the general population. The results of the two groups were compared statistically using chi(2) tabulation. RESULTS: Seventy four (80%) of the managers responded to the questionnaire. Nine of the 68 ex-professional footballers who replied had OA of the hip, and six of these had undergone a total of eight total hip replacements. Of the 18 managers who did not respond, 12 were known to be ex-professionals. In the control group of 136, two had OA of the hip. The two groups differed significantly (p<0.001). The odds ratio for OA of the hip was 10.2 (95% confidence interval 2.1 to 48.8). CONCLUSION: The ex-professional footballers had a significantly higher prevalence of OA of the hip than an age matched group of radiographic controls.

Gridiron football injuries.

OBJECTIVE: To review the available football epidemiology literature to identify risk factors, facilitate injury prevention and uncover deficiencies that may be addressed by future research. DATA SOURCES: A literature search of Sports Discus (1940-2003), Eric (1967-2003), EMBASE (1988-2003), MEDLINE (1966-2003), CINAHL (1984-2003), and Web of Science (1993-2003) identified the published articles on American football in athletes of high school age and younger. MAIN RESULTS: Injury rate increases with the level of play (grade in school), player age, and player experience. The lower extremity (knee and ankle joints) is most frequently injured. Football injuries are much more common in games than in practice, and occur to players who are being tackled, tackling or blocking. Most injuries are mild, including contusion, strain and sprain. Rule changes with the prohibition of initial contact with the helmet or face-mask reduced catastrophic head and neck injuries. CONCLUSION: Although no sport or recreational activity is completely risk-free, football epidemiology research is critical to injury prevention. The existing medical literature provides some valuable insights, but an increased emphasis on prospective research is required to test the efficacy of preventative measures. Quality research may contribute to a reduction in football injury risk by defining the role of player conditioning and strength training, coaching of safety fundamentals, avoidance of dangerous activities, as well as proper medical supervision and care. Sports medicine personnel, coaches, and officials must strive to minimize injuries through progressive education, improved coaching techniques, effective officiating, and equipment modifications.

Relationship between radiographic abnormalities of lumbar spine and incidence of low back pain in high school and college football players: a prospective study.

BACKGROUND: Low back pain is a common presenting symptom among players of American football. In Japan, however, skeletal disorders in football players, including low back problems, have been rarely studied, and management to prevent skeletal disorders has not been established. STUDY DESIGN: An epidemiological study with prospective observation. METHODS: The authors analyzed the relationship between lumbar spine abnormalities viewed through radiographs taken during the preparticipation physical examination, and the incidence of low back pain during a 1-year period in 171 high school and 742 college football players. Abnormalities assessed were spondylolysis, disc space narrowing, spinal instability, Schmorl's node, balloon disc, and spina bifida occulta. RESULTS: High school players with spondylolysis had a higher incidence of low back pain (79.8%) than those with no abnormal radiographic results (37.1%). College players with spondylolysis, disc space narrowing, and spinal instability had a higher incidence of low back pain (80.5%, 59.8%, and 53.5%, respectively) than those with no abnormal radiographs (32.1%), and college players with spondylolysis had a higher incidence of low back pain than those with disc space narrowing and spinal instability. CONCLUSIONS: The results of the present study suggest that an abnormality such as spondylolysis is the most significant risk factor for low back pain in high school and college football players, and that disc space narrowing and spinal instability are also significant risk factors for low back pain in athletes with greater athletic activity such as college football players.

Hyperconcavity of the lumbar vertebral endplates in the elite football lineman.

BACKGROUND: Hyperconcavity of the vertebral endplates is a previously unreported radiologic phenomenon. PURPOSE: To analyze hyperconcavity of the vertebral endplates with expansion of the disk space in pre-National Football League lineman and to determine its clinical significance. STUDY DESIGN: Descriptive anatomical study. METHODS: Over a 2-year period (1992-1993), 266 elite football linemen were evaluated at the National Football League scouting combine held in Indianapolis, Indiana. Evaluation focused on the lumbosacral spine and included history, physical examination, and lateral radiographs. Measurements were taken of all the vertebral endplate defects of involved vertebrae and compared with an age-matched control group of 110 patients. RESULTS: The analyzed data revealed the following: (1) hyperconcavity of the vertebral endplates appeared as a distinct entity in a high percentage of pre-National Football League lineman (33%) compared with age-matched controls (8%), (2) there was a trend toward a lower incidence of lumbosacral spine symptoms in those players who displayed hyperconcavity of the vertebral endplates (16%) versus those who did not (25%), and (3) when hyperconcavity of the vertebral endplates was present, all 5 lumbosacral disk spaces were commonly affected. CONCLUSIONS: Hyperconcavity of the vertebral endplates and hypertrophy of the disk space are likely adaptive changes occurring over time in response to the repetitive high loading and axial stress experienced in football line play.

Hydration status in college football players during consecutive days of twice-a-day preseason practices.

BACKGROUND: Football players lose 3.5 to 5 kg of body weight during preseason practices because of heavy sweating. This fluid may be difficult to replace when practices occur 2 times per day on consecutive days. HYPOTHESIS: Football players are hypohydrated during twice-a-day preseason training in a hot, humid environment. STUDY DESIGN: Descriptive laboratory study. METHODS: In 10 college football players, body weight was measured, and blood and urine samples were obtained before and after practices on days 2 through 8 of preseason training. Baseline samples were obtained when subjects were euhydrated. Blood samples were used to calculate plasma volume changes. Urine samples were analyzed for specific gravity, sodium, and potassium. Sweat rate was calculated. Core temperature was monitored during half- and full-padded practices. RESULTS: Mean wet bulb temperatures were 23.3 degrees C during morning practices and 23.7 degrees C during afternoon practices. Plasma volume was below baseline on day 2 and expanded by day 6. Urine specific gravity was higher than baseline for 12 of 20 measurements over the 8 days. It was 1.0175 +/- 0.006 at baseline but subsequently ranged from 1.0214 +/- 0.007 to 1.0321 +/- 0.004. Mean daily urine sodium dropped from baseline to day 2 (194 +/- 43 vs 43 +/- 38 mmol x L-1), remaining lower on days 3, 4, and 6 (40 +/- 39, 39 +/- 39, and 68 +/- 40 mmol x L-1, respectively). Urine potassium was lower on days 6 and 8 compared with baseline and day 3. Body weight was below baseline before and after both daily practices. Core temperature was higher in full pads; sweat rate and body weight loss were not different between half and full pads. CONCLUSION: Body weight, plasma volume, urine specific gravity, and urine sodium indicate that football players become dehydrated by day 2 of preseason training. Urine sodium increased to near baseline by day 8; urine specific gravity was elevated. CLINICAL RELEVANCE: Football players struggle to maintain euhydration during preseason twice-a-day sessions.

Football equipment design affects face mask removal efficiency.

BACKGROUND: Researchers have investigated the performance of face mask removal tools for spine injury management in football but not the effects of football equipment design. HYPOTHESES: Various styles or designs of football helmet equipment (helmets, face masks, loop straps) affect face mask removal efficiency. A cordless screwdriver performs more efficiently than do cutting tools. STUDY DESIGN: Controlled laboratory study. METHODS: Nineteen certified athletic trainers were randomly assigned to group 1 (cordless screwdriver and the FM Extractor) or group 2 (cordless screwdriver and the Trainer's Angel). Subjects randomly performed face mask removal for 6 conditions composed of helmet (3), face mask (3), and loop strap (5) combinations. Time, head movement, perceived difficulty, and success rates were measured. RESULTS: Multiple significant differences were found in time, movement, and perceived difficulty between the 6 helmet equipment conditions. The Shockblocker loop strap was consistently superior in all variables regardless of the tool used or the helmet it was attached to. The cordless screwdriver created less movement (mean range from any one plane, 2.8 degrees -13.3 degrees ), was faster (mean range, 42.1-68.8 seconds), and was less difficult (mean rating of perceived exertion range, 1.4-2.9) compared to cutting tools (ranges, 4.4 degrees -18.4 degrees in any one plane, 71-174 seconds, rating of perceived exertion, 2.8-7.7). Trial failure was more common with cutting tools than with the screwdriver. CONCLUSION: Differences in football helmet equipment affect face mask removal. The cordless screwdriver is more efficient than the FM Extractor and Trainer's Angel. CLINICAL RELEVANCE: Professionals responsible for the care of football athletes must be knowledgeable in the types of equipment used and the best option available for effective airway access.

Prevalence and variance of shoulder injuries in elite collegiate football players.

BACKGROUND: Shoulder injuries are the fourth most common musculoskeletal injury encountered in American football players. There is little information in the literature on the role of playing position in the type of shoulder injuries seen. HYPOTHESIS: There is a high prevalence of shoulder injuries in elite collegiate American football players, with type of injury varying by playing position. STUDY DESIGN: Cohort study (prevalence); Level of evidence, 3. METHODS: A total of 336 elite collegiate American football players were invited to the National Football League Combine for physical testing and medical evaluation. Current and historical data were evaluated for the purpose of this study, and all players underwent radiographic examinations, including plain radiographs and/or magnetic resonance imaging when necessary. All shoulder pathological conditions and shoulder surgical procedures were recorded. Players were categorized by position for the analysis of position-specific trends. RESULTS: Of the players, 50% had a history of shoulder injuries, with a total of 226 shoulder injuries (1.3 injuries per player injured); 56 players (34%) had a total of 73 surgeries. The most common injuries were acromioclavicular separation (41%), anterior instability (20%), rotator cuff injury (12%), clavicle fracture (4%), and posterior instability (4%). The most common surgeries performed were anterior instability reconstruction (48%), Mumford/Weaver-Dunn surgery (15%), posterior instability surgery (10%), and rotator cuff surgery (10%). Shoulder injuries were more common in quarterbacks and defensive backs. Surgery was more common in linebackers or linemen. A history of anterior instability was more common in defensive players, with surgery required 76% of the time. Linemen had more rotator cuff injuries and posterior instability than players in other positions. CONCLUSION: Shoulder injuries are common injuries in elite collegiate football players, with one-third undergoing surgical procedures. There are definitive trends in the types of injuries per player position.

Outcomes of anterior cruciate ligament injuries to running backs and wide receivers in the National Football League.

BACKGROUND: Anterior cruciate ligament injuries are common in professional football players, and their career impact is unclear. PURPOSE: To quantify the affect of anterior cruciate ligament injuries on professional football player performance. STUDY DESIGN: Cohort study (prognosis); Level of evidence, 2. METHODS: Anterior cruciate ligament injury data from the National Football League were collected during a 5-year period (1998-2002) for running backs and wide receivers. Recorded variables included player age, experience, position, time to return to competition, and yearly total yards and touchdowns. Power ratings (total yards divided by 10 plus touchdowns multiplied by 6) were calculated for the injury season as well as for the 3 seasons before and after injury. A control group consisted of all running backs and wide receivers without an identified anterior cruciate ligament injury who competed in the 2000 season. RESULTS: Data were analyzed for 31 running backs and wide receivers with 33 anterior cruciate ligament injuries. More than one fifth of players never returned to a National Football League game. Returning players first competed in a game 55.8 +/- 5.4 weeks (mean +/- standard error) after injury. For the 24 anterior cruciate ligament-injured players with a minimum total power rating (sum of all 7 seasons) of 200 points, power rating per game played decreased from 9.9 +/- 1.1 preinjury to 6.5 +/- 0.9 postinjury. This decline in power rating per game played was statistically significant (P = .002) when compared with the change for the 146 control players. CONCLUSION: Nearly four fifths of National Football League running backs and wide receivers who sustain an anterior cruciate ligament injury return to play in a game. On return to competition, player performance of injured players is reduced by one third.

Radiographic abnormalities of the lumbar spine in college football players. A comparative analysis.

The purpose of this study was to make a direct comparison between lumbar spine radiographs of incoming college football players and of an age-matched control group to determine whether there is a higher prevalence of lumbar spine abnormalities in football players before competing at the Division I level. We reviewed 187 lumbar spine radiographs. Of these, 104 were taken as a standard part of the preparation physical examination for incoming college football players. The remaining 83 radiographs were taken during routine preemployment physicals at a local factory. Each radiograph was read independently by three separate orthopaedic radiologists in a blinded fashion. Data were collected and statistically evaluated for 13 variables. The rate of spondylolysis was only 4.8% in our group of athletes and 6.0% in the control group (not significantly different). Only in the category of degenerative changes was a significant difference found. The control group had a 16.9% incidence of disk space narrowing and spurring and the football players had a 6.7% incidence. The remainder of the variables were not significantly different between the two groups. Our findings differ from previously published reports and indicate that football players entering college at the Division I level may have a similar prevalence of radiographic lumbar spine abnormalities, including spondylolysis and spondylolisthesis, as age-matched controls.

Psychological and sport-specific characteristics of football players.

It is hypothesized that players of different levels of play might differ not only in their football skills but also in their way of playing football and with respect to psychological factors such as concentration, reaction time, or competitive anxiety. The psychological characteristics of a player might influence his way of playing football (in particular with respect to fair play) and also his risk of injury. A group of 588 football players were studied by questionnaire; additionally, reaction time tests were performed. Psychological characteristics were assessed by three established self-evaluation questionnaires: the Athletic Coping Skills Inventory, the State Competitive Anxiety Test, and the State-Trait-Anger-Expression-Inventory. Football-specific characteristics that were investigated included playing experience and positions played, style of play, number of training hours and games, as well as aspects of fair play. Reaction time was tested twice: without the influence of physical exercise and immediately after a 12-minute run. A significant reduction in reaction time was observed after physical exercise. In high-level players, the reaction time immediately after the 12-minute run was significantly shorter than it was in low-level players. The questionnaire answers given regarding fair play clearly indicated that fair play is not paid sufficient respect. The relationship between psychological characteristics and attitudes toward fair play was analyzed and discussed.
