BACKGROUND: Fast-bowlers in cricket subject their spines to repetitive stress. OBJECTIVES: The aim of this study was to review the prevalence of lumbar spine injuries among fast-bowlers. MATERIALS AND METHODS: Medline and embase searches were performed. Further, the authors canvassed the reference list of available articles and used other search engines such as Google Scholar to identify a total of nine studies. RESULTS: The prevalence of lumbar disc degeneration in fast-bowlers ranges from 21-65% with an incidence rate of 15% per year, and the prevalence of lumbar spine bony abnormalities ranges from 24-81%. Factors associated with lumbar spine injury in fast-bowlers are classified into un-modifiable (age) and modifiable (more intense bowling workload and mixed-bowling technique). CONCLUSIONS: Fast-bowlers have a high prevalence of lumbar spine injuries. Appropriate interventions, such as educational sessions, may be able to modify risk factors such as bowling workload and bowling technique and thus reduce injury prevalence.

Golf is a popular sport with both perceived and real health benefits. However, certain injury risks are also prevalent, particularly to the lower back. Epidemiological studies have shown that lower back pain (LBP) from golf account for between 18% and 54% of all documented ailments, leading many researchers to regard the condition as the most common golf injury. The purpose of this review was to examine the scientific literature to ascertain the risk factors associated with the development of LBP from playing golf and suggest methods to modify or limit these factors. Results of the review indicate that the high frequency of LBP appears multi-factorial although the asymmetrical and forceful nature of the swing along with excessive play and practice, particularly amongst elite players, appear to be common factors. Other factors include swing flaws leading to excessive side-bend and over-rotation of the spine, abnormal muscle recruitment, poor trunk endurance, restricted lead hip internal rotation and the use of unnecessarily stressful club transportation methods. Methods to help control or eliminate excessive stress on the lower back would include reducing the amount spent playing or practicing, seeking professional assistance to assess and adjust swing mechanics, improve trunk and hip flexibility, increase the strength and endurance of the trunk musculature, consider different footwear options and avoid carrying the golf bag. Adopting some or all of these recommendations should allow players to continue to enjoy the sport of golf well into their senior years.

While degenerative lumbar spine conditions are common in the general population, there are unique considerations when diagnosed in high-level athletes. Genetic factors have been identified as a more significant contributor to the development of degenerative disc disease than occupational risks, however, some have postulated that the incessant training of young, competitive athletes may put them at a greater risk for accelerated disease. The evidence-based literature regarding lumbar disc herniation in elite athletes suggests that it is reasonable to expect excellent clinical outcomes and successful return-to-sport after either operative or non-operative treatment regardless of sport played. However, those athletes who require repetitive torque on their lumbar spines may have poorer long-term outcomes if surgical treatment is required for this condition. Painful spondylolysis in the athlete can often be treated successfully with non-operative treatment, however, if surgery is required, pars repair techniques provides a motion-sparing alternative that may lead to successful return to sport.

BACKGROUND: Low back pain (LBP) is a common cause of lost playing time and can be a challenging clinical condition in competitive athletes. LBP in athletes may be associated with joint and ligamentous hypermobility and impairments in activation and coordination of the trunk musculature, however there is limited research in this area. OBJECTIVES: To determine if there is an association between altered lumbar motor control, joint mobility and low back pain (LBP) in a sample of athletes. MATERIALS AND METHODS: Fifteen athletes with LBP were matched by age, gender and body mass index (BMI) with controls without LBP. Athletes completed a questionnaire with questions pertaining to demographics, activity level, medical history, need to self-manipulate their spine, pain intensity and location. Flexibility and lumbar motor control were assessed using: active and passive straight leg raise, lumbar range of motion (ROM), hip internal rotation ROM (HIR), Beighton ligamentous laxity scale, prone instability test (PIT), observation of lumbar aberrant movements, double leg lowering and Trendelenburg tests. Descriptive statistics were compiled and the chi square test was used to analyze results. RESULTS: Descriptive statistics showed that 40% of athletes with LBP exhibited aberrant movements (AM), compared to 6% without LBP. 66% of athletes with LBP reported frequently self-manipulating their spine compared to 40% without LBP. No significant differences in motor control tests were found between groups. Athletes with LBP tended to have less lumbar flexion (63 ± 11°) compared to those without LBP (66 ± 13°). Chi-Square tests revealed that the AM were more likely to be present in athletes with LBP than those without (X2 = 4.66, P = 0.03). CONCLUSIONS: The presence of aberrant movement patterns is a significant clinical finding and associated with LBP in athletes.

BACKGROUND: Low Back Pain (LBP) is one of the most prevalent causes of disability not only in the general population but also in athletes. Despite a large number of self-reported back specific disability questionnaires, there is no specific, well documented, outcome measure for athletes suffering from back pain. OBJECTIVES: This study aimed to identify the main descriptive themes representing functional disability in athletes due to LBP. PATIENTS AND METHODS: We conducted a qualitative study using in-depth interviews to characterize the experiences of athletes with LBP. Twenty athletes with LBP were recruited and the main descriptive elements of their LBP related disability were extracted. Then a preliminary questionnaire using these themes was proposed. RESULTS: The main disability indicators were pain intensity; stretching exercises, strengthening exercises, sport specific skills, back range of motion (ROM), sitting, walking, sleep patterns, self-care, and recreational activities, fear of pain and avoidance behavior, and changes in sexual activity. CONCLUSIONS: The findings of this study suggest that apart from non-sports items, some sport related items should be included in the assessment of LBP disability levels in athletes. Our results have also been organized as a preliminary LBP disability questionnaire for athletes.

INTRODUCTION: The self-administration intake of anabolic-androgenic steroids (AAS) is a widespread practice in competitive bodybuilders. Structural changes within the myocardium following AAS abuse including hypertrophy, restricted diastolic function as well as systolic dysfunction and impaired ventricular inflow have been reported. CASE PRESENTATION: We present the case of a 39-year-old bodybuilder with a more than 20-year history of anabolic-androgenic steroids (AAS) abuse presenting with increasing exertional dyspnoea and fatigue. Diagnostic work-up of the patient's current symptoms included a cine cardiovascular magnetic resonance (CMR). Using a T1-weighted inversion-recovery sequence 10 minutes after application of 0.1 mmol/kg gadolinium with diethylenetriaminepentaacetic acid (gadolinium DTPA), patchy midwall enhancement in the septal and posterolateral region of the left ventricle was demonstrated. This enhancement pattern is different from the enhancement pattern found in patients with ischemic heart disease. CONCLUSIONS: The present case illustrates for the first time, by CMR, myocardial scarring with severe left ventricular hypertrophy in a patient with normal coronary arteries after long lasting abuse of AAS. With that finding we could demonstrate a link between AAS abuse and the occurrence of myocardial scarring in humans. This finding may help raise awareness of the consequences of AAS use.

BACKGROUND: Although guidelines based on expert opinions have been developed for the immediate management and return to play of athletes after a concussion, data are lacking on this issue. OBJECTIVES: Evaluate a standardized management of brain concussion among rugby players to prevent the recurrence. PATIENTS AND METHODS: A prospective study was performed from September 2009 to June 2012. All rugby players who had a concussion when playing rugby were included. Patients were managed by a specialized hospital team with a specific protocol developed in collaboration with the medical staff of the rugby clubs included in the study. The series included 35 rugby players, with 23 professionals and 12 high-level players, 30 men and 5 women, mean age 23.1 ± 5.5 years old. The median number of previous concussions was 2 (0-30) episodes. According to the Cantu concussion severity classification, 3 athletes were grade 1, 12 were grade 2 and 20 were grade 3. None of the injured athletes was lost to follow-up. The primary endpoint was the occurrence of a new concussion within 3 months after the first in patients who returned to rugby. RESULTS: Thirty-three patients returned to rugby after a mean 22.1 ± 10 days. The recurrence rate within 3 months was 2/33 (6.1%). The median delay before returning to rugby was 21 (7-45) days. Factors associated with a delayed return to play were young age, initial loss of consciousness, severity Cantu grade 3 and post-concussive syndrome of more than 5 days. Analysis of two failures showed that the initial injury was grade 3 and that both were professional athletes and had a history of concussion. CONCLUSIONS: This prospective study validated the study protocol for the management of concussion in rugby players.

BACKGROUND: Fatigue seems to have a significant effect on soccer kick performance. However, the duration of these effects has not been previously investigated. OBJECTIVES: The purpose of the present study was to investigate the duration of the acute effects of fatigue on soccer kick performance in males and females. PATIENTS AND METHODS: Ten male (age: 26.3 ± 4.9 years, height: 178.1 ± 5.1 cm, mass: 81.3 ± 8.1 kg) and ten female (age: 24.4 ± 4.2 years, height: 169.7 ± 5.7 cm, mass: 61.8 ± 5.1 kg) amateur soccer players performed three instep kicks prior to and after running on a treadmill till exhaustion. Three-dimensional kinematics were collected pre- and post-fatigue. RESULTS: Analysis of variance indicated a statistically significant decline in ball speed during the first and the second trial after fatigue (P < 0.05), but recovered to pre-fatigue levels during the third post-fatigue kicking trial (P > 0.05). Similarly, maximum ankle, knee and hip linear velocity and ankle angular displacement were significantly lower during the first two trials (P < 0.05), but not during the third trial after fatigue (P > 0.05). CONCLUSIONS: Soccer kick parameters recovered to pre-fatigue levels approximately within a minute after the end of the protocol. These findings have a practical meaning for players who have to perform set piece kicks under fatigue conditions and for coaches who have to guide their players.

BACKGROUND: Wrestling was an important part of the ancient Olympic Games and is still one of the most popular events of the modern Olympic Games. Studies indicate that general physiologic profile of successful wrestlers is high anaerobic power and capacity, muscular strength, above average aerobic power, exceptional flexibility, fat free mass, and a mesomorphic somatotype. OBJECTIVES: The objective of the present study was to evaluate anthropometric characteristics and physical performance of elite male wrestlers. PATIENTS AND METHODS: The Colombian Wrestling Team was evaluated while in preparation for the Olympic Games (n = 21; age, 27.9 ± 6.7 years). Athletes were tested on anthropometric and fitness parameters: body composition, somatotype distribution according to Heath-Carter, aerobic capacity, vertical jump, and anaerobic power. RESULTS: The evaluations showed a mean body fat percentage of 13.6% ± 3.0% (95% CI, 12.2%-15%), muscle mass of 46.4% ± 2.2% (95% CI, 45.4%-47.4%), Ponderal index of 41.0 ± 1.8 (95% CI, 40.2-41.8), body adiposity index (BAI) 25.1 ± 3.6 (95% CI, 23.5-26.8), and somatotype distribution mesomorphic-ectomorph (5.3-1.6-3.8). Mean aerobic capacity was 45.9 ± 6.6 mL/kg/min (95% CI, 42.8-48.9), vertical jump was 36.4 ± 6.6 cm (95% CI, 11.8-16.6), and anaerobic power was 92.6 ± 19.5 kg/s (95% CI, 83.7-101.5). CONCLUSIONS: These results provided a profile of elite wrestlers that could be used as training targets for developing athletes. The results may also provide information for training and tactical planning.

BACKGROUND: By providing sports organizations with electronic records and instruments that can be accessed at any time or place, specialized care can be offered to athletes regardless of injury location, and this makes the follow-up from first aid through to full recovery more efficient. OBJECTIVES: The aim of this study was to develop an electronic personal health record for professional Iranian athletes. PATIENTS AND METHODS: First, a comparative study was carried out on the types of professional athletes'existing handheld and electronic health information management systems currently being used in Iran and leading countries in the field of sports medicine including; Australia, Canada and the United States. Then a checklist was developed containing a minimum dataset of professional athletes' personal health records and distributed to the people involved, who consisted of 50 specialists in sports medicine and health information management, using the Delphi method. Through the use of data obtained from this survey, a basic paper model of professional athletes' personal health record was constructed and then an electronic model was created accordingly. RESULTS: Access to information in the electronic record was through a web-based, portal system. The capabilities of this system included: access to information at any time and location, increased interaction between the medical team, comprehensive reporting and effective management of injuries, flexibility and interaction with financial, radiology and laboratory information systems. CONCLUSIONS: It is suggested that a framework should be created to promote athletes' medical knowledge and provide the education necessary to manage their information. This would lead to improved data quality and ultimately promote the health of community athletes.

BACKGROUND: Research on the effects of exercise on immune function, has a wide range of sporting activities. Study on the long-term effects of regular exercise on serum levels of cytokines such as interleukin-17 have shown that moderate and regular exercise, has an important role in the prevention and treatment of many diseases. OBJECTIVES: Exhaustive exercise has a deep effect on cellular, humoral, innate immunity and the amount of cytokines of an athlete's immune system. So this study was designed to compare the effect of one course of exhaustive exercise on serum levels of interleukin (IL)-17 in different groups of athletes. PATIENTS AND METHODS: Forty professional athletes with a mean age of 25.1 ± 5.0 years, divided equally in 4 groups (handball, volleyball, Sepak-takraw and climbing) were selected for this purpose. 30 second Wingate test for each athlete was used to assess anaerobic power. Blood samples before, immediately after and 2 hours after exercise was collected and the amount of serum IL-17 was measured. RESULTS: The results showed that the level of IL-17 in the study groups before and after the two hours exercise did not significantly change in all four groups. CONCLUSIONS: The results showed that short anaerobic exercise has no effect on the level of IL-17.

INTRODUCTION: Non-traumatic knee joint effusion and fullness is a relatively common presenting complaint among athletes and non-athletes. Due to its broad differential diagnosis, a comprehensive evaluation beginning with history and physical examination are recommended. Imaging including plain radiography, magnetic resonance imaging (MRI), and in some cases ultrasound are preferred modalities. If inflammatory arthritis is suspected, joint aspiration and analysis may help diagnosis. CASE PRESENTATION: A 37-year-old male soccer player presented with a complaint of left anterior knee pain and fullness for a few months. Physical examination revealed a healthy appearing male with obvious fullness of his left suprapatellar pouch and posterolateral knee. Plain radiographs were unremarkable. MRI demonstrated an effusion infiltrated by multiple, low intensity projections from a fatty mass in the suprapatellar pouch consistent with lipoma arborescens. CONCLUSIONS: Lipoma arborescens is a rare synovial disorder characterized by replacement of subsynovial tissue with mature fat cells, most commonly in the knee joint. MRI is the best diagnostic modality to evaluate and confirm the diagnosis as well as rule out other pathologies. More recent single case-reports and clinical series endorse arthroscopic synovectomy as the treatment of choice.

BACKGROUND: Cryotherapy, in the form of ice massge is used to reduce inflammation after acute musculoskeletal injury or trauma. The potential negative effects of ice massage on proprioception are unknown, despite equivocal evidence supporting its effectiveness. OBJECTIVES: The purpose of the study was to test the influence of cooling on weight discrimination ability and hence the performance in footballers. PATIENTS AND METHODS: The study was of same subject experimental design (pretest-posttest design). Thirty male collegiate football players, whose mean age was 21.07 years, participated in the study. The participants were assessed for two functional performance tests, single leg hop test and crossed over hop test and weight discrimination ability before and after ice massage for 5 minutes on hamstrings muscle tendon. RESULTS: Pre cooling scores of Single Leg Hop Test of the dominant leg in the subjects was 166.65 (± 10.16) cm and post cooling scores of the dominant leg was 167.25 (± 11.77) cm. Pre cooling scores of Crossed Over Hop Test of the dominant leg in the subjects was 174.14 (± 8.60) cm and post cooling scores of the dominant leg was 174.45 (± 9.28) cm. Pre cooling scores of Weight Discrimination Differential Threshold of the dominant leg in the subjects was 1.625 ± 1.179 kg compared with post cooling scores of the dominant leg 1.85 (± 1.91) kg. Pre cooling scores of single leg hop and crossed over hop test of the dominant leg in the subjects compared with post cooling scores of the dominant leg showed no significant differences and it was also noted that the weight discrimination ability (weight discrimination differential threshold) didn't show any significant difference. All the values are reported as mean ± SD. CONCLUSIONS: This study provides additional evidence that proprioceptive acuity in the hamstring muscles (biceps femoris) remains largely unaffected after ice application to the hamstrings tendon (biceps femoris).

BACKGROUND: To determine the 2D:4D ratio in elite Indian male kabaddi players and compare them with non-athletes. OBJECTIVES: Our study was undertaken to find out a possible relation between digit ratio and sporting ability of male kabaddi players. This study also gives an insight into the possible ethnic differences between Indian sports personnel and other populations. PATIENTS AND METHODS: Both right and left hands of 33 male kabaddi players attending training camp at the Bangalore regional centre of Sports Authority of India were scanned. Lengths of second and fourth digits were measured and their ratio calculated. Age, weight, height and body mass index matched subjects (25 males) who did not participate in any sports formed the control group. RESULTS: A highly significant difference was found in 2D:4D ratios of both the hands with Kabaddi players having a lower ratio compared to their controls. There was no statistically significant difference in 2D:4D (Δ r-l) between Kabaddi players and controls. CONCLUSIONS: Kabaddi is an intermediate sport not requiring a high level of endurance but at the same time requires masculine traits because of combating nature of the game. 2D:4D ratios can be used as reliable additional criteria when screening for prospective players to be inducted into the team.

BACKGROUND: Injuries are common in contact sports like Australian football. The Australian Football League (AFL) has developed an extensive injury surveillance database that can be used for epidemiological studies. OBJECTIVES: The purpose of this study is to identify any association between the three most prevalent injuries in the AFL. PATIENTS AND METHODS: From the AFL injury surveillance data 1997-2012 the injury incidence (new injuries per club per season) and the injury prevalence data (missed games per club per season) were analysed to detect the three most common injuries that would cause a player to miss a match in the AFL. The three most prevalent injuries in the AFL are hamstring strains, groin/hip/osteitis pubis injuries and Anterior Cruciate Ligament (ACL) knee injuries. Following this, further study was undertaken to detect the presence of any statistical relationship between injury incidences of the three most prevalent injuries over this sixteen year study period. RESULTS: Statistical analysis demonstrates for any given year that there was an association between having a groin/hip/osteitis pubis injuriy and having a knee ACL injury (P < 0.05) over the entire sixteen years. In other words if the number of groin/hip/osteitis pubis injuries in any given season were higher than average (alternatively lower) then the number of knee ACL injuries were also higher than average (alternatively lower) for that same season. Hamstring injuries had the highest variance of incidence of the three most prevalent injuries. CONCLUSIONS: Analysis of the AFL injury data demonstrates an association between incidence of groin/hip/osteitis pubis injuries and incidence of knee ACL injuries for any given playing season. This finding is difficult to explain with further research being required.

BACKGROUND: Futsal is a growing sport with lots of fans in many countries including Iran, but there are few papers in the literature which report injuries in top level futsal. OBJECTIVES: The aim of this study is to record and analyze the incidence and characteristics of injuries in Iran futsal national teams from March 2011 to September 2012. PATIENTS AND METHODS: 55 Iranian national futsal players participated in this prospective cohort study. Before entering the study, all players took part in Pre-Competition Medical Assessment (PCMA) in accordance with FIFA protocol. Team physicians recorded the injuries throughout the match and trainings in a special form which was designed for this purpose. Finally, data analysis was done with the SPSS software. RESULTS: The total exposure time for all players was 24326 hours (21138 hours during training and 3188 hours during matches). During the study period, 32 of the 55 national players (58.2%) incurred 54 injuries (incidence rate = 2.22 injuries per 1000 players-hours). The incidence rate of injury in female players was significantly higher than male players (P = 0.001). The majority of injuries (85.2%) were located on the lower extremities. The ankle was the most frequent injury location (40.7%) and sprain was the most frequent type of injury. CONCLUSIONS: Injuries are common among futsal players and female players are more prone to injuries than male players. The ankle is the most frequent site and sprain is the most frequent type of injury among futsal players.

BACKGROUND: Delayed onset muscle soreness (DOMS) occurs following unaccustomed or intense bouts of exercise. Previous research has demonstrated that that preconditioning with low load exercise or heat relieves muscle soreness. However, actively warming up the muscles with exercise may be an effective alternative. OBJECTIVES: This study compared preconditioning effect of light load eccentric exercise and heat using microwave diathermy on markers of muscle damage in collegiate males. PATIENTS AND METHODS: Thirty six sedentary collegiate males were randomly assigned into two experimental groups: 10% Eccentric exercise group (10% ECC group) and Microwave diathermy group (MWD group). Both the groups performed 30 repetitions of maximal eccentric exercise (Max-ECC) of the elbow flexors. The 10% ECC group performed light load eccentric exercise (10% ECC), five sets, six repetitions using a dumbbell set at 10% of maximal voluntary isometric contraction strength (MVC), 2 days prior to Max-ECC. The MWD group received heat using microwave diathermy (150 watts, 20 minutes) one day prior to Max-ECC. Changes in MVC, range of motion (ROM), upper arm circumference, soreness, were assessed before and 24-72 hours after whereas serum creatine kinase activity and lactate dehydrogenase (LDH) activity up to 48 hours following the Max-ECC were compared between groups by a mixed model ANOVA. RESULTS: No significant difference (P > 0.05) were found between the groups for changes in all variables post Max-ECC, except for LDH activity showing significant interaction effect (P = 0.04). CONCLUSIONS: Preconditioning with light load eccentric exercise and heat using microwave diathermy treatment did not differ in their effects on muscle damage markers after Max-ECC. However, with time their effects on LDH activity were found to be different.

CONTEXT: Motor impairments in individuals with autism spectrum disorder (ASD) have been frequently reported. In this review, we narrow our focus on postural control impairments to summarize current literature for patterns, underlying mechanisms, and determinants of posture in this population. EVIDENCE ACQUISITION: A literature search was conducted through Medline, ISI web of Knowledge, Scopus and Google Scholar to include studies between 1992 and February 2013. RESULTS: Individuals with ASD have problems in maintaining postural control in infancy that well persists into later years. However, the patterns and underlying mechanisms are still unclear. CONCLUSIONS: Examining postural control as an endophenotype or early diagnostic marker of autism is a conceptual premise which should be considered in future investigations. At the end of the review, methodological recommendations on the assessment of postural control have also been provided.
