ABSTRACT Introduction Small-sided games (SSG) are used as training tools for physical conditioning in soccer. To date, however, it is unknown whether team composition affects athletes’ physical performance. Specifically, based on the differences presented by players of different positions, it is expected that the use of positional status as a criterion for team composition will affect players’ physical performance. Objective To compare the physical demands of SSG in teams composed of young soccer players in the same position or different positions. Methods 12 U-15 soccer players participated in the study. The athletes performed 3v3 SSGs under two conditions: teams in which the athletes played in the same position (i.e. three defenders), and teams in which the players took up different positions (i.e. defender, midfielder and attacker). Data were obtained on total distance traveled, distance in speed zones, and accelerations, using GPS devices. The data were analyzed using the paired t-test, comparing the two experimental conditions. Results There was higher physical demand among defenders and midfielders when the SSG was performed with athletes playing in the same position, in terms of distances covered in different speed zones. However, there were no differences in relation to acceleration actions. Conclusion Team composition affects the physical performance of soccer athletes during 3v3 SSG.

Background Professional and amateur soccer players often perform dramatic on-field feats of celebration after scoring a goal. Injuries may occur during these activities. Purpose With the aim of preventing such “score-celebration injuries” in the future, the authors examine these events in professional soccer players and discuss potential avenues for prevention. Study Design Case series; Level of evidence, 4. Methods Over the course of 2 seasons (1996-1998), 152 soccer players were evaluated at an orthopaedic clinic for injuries incurred during matches. Nine players (6%) had injured themselves while celebrating after scoring goals in a match. The type of celebration, injury type, treatment, and mean duration of recovery were noted. Results Seven of the 9 patients were male professional soccer players with ages ranging between 17 and 29 years (mean age, 24 years). The injuries occurred when the playing ground was natural turf in 8 cases; most injuries occurred in the second half of the game. The types of celebration maneuvers were sliding (prone or supine) and sliding while kneeling in 5 cases, piling up on jubilant teammates in 3 cases, and being tackled while racing away in 1 case. Injuries included ankle, clavicle, and rib fractures; medial collateral ligament sprain; low back strain; hamstring and adductor muscle strain; quadriceps muscle sprain; and coccyx contusion. The mean duration for recovery was 6.2 weeks. Rival team players were usually not responsible for such trauma. Conclusion Exaggerated celebrations after making a goal, such as sliding, piling up, and tackling a teammate when racing away, can result in serious injury. In addition to general measures for preventing soccer injuries, coaches and team physicians should teach self-control and behavior modification to minimize the risk of such injuries. More restrictive rules, which penalize such behavior, may assist in the prevention of score-celebration injuries.

ABSTRACT Introduction: The Brazilian Army (BA) considers Military Physical Training (MPT) essential for the development of physical conditioning and general health, including prevention of chronic noncommunicable diseases (CNCDs), including metabolic syndrome (MS) risk factors. The evaluation of body composition using dual-emission x-ray absorptiometry (DXA) quantifies the visceral fat responsible for several types of disease. Objective: To verify the behavior among the body composition, anthropometric, hemodynamic and biochemical variables by means of the physical performance of military personnel with MS (W/MS) and without MS (NO/MS). Methods: The sample consisted of 41 (38.9 ± 2.3 years, 177.8 ± 6.4 cm, 91.5 ± 11.9 kg) military personnel, with 28 individuals diagnosed as W/MS and 13 individuals as NO/MS. Data collection was divided into three days. An anthropometric assessment was performed on the first day. On the second day, the subjects underwent biochemical tests of MS markers, blood pressure (BP) checks, and DXA examinations. On the third day, a physical assessment was applied according to the requirements of the BA (12-minute run, pushups and pullups). Results: There was a significant difference between W/MS and NO/MS subjects in the variables of HDL-C, Diastolic BP, Systolic BP and Waist Circumference. None of the physical variables presented a significant difference. There was also a significant difference between groups for all body composition and anthropometric variables. Conclusion: NO/MS subjects have better mean body composition, BP and anthropometric values than W/MS subjects, which may indicate that they are at less risk of CNCDs. The fact that the military subject is or is not a carrier of MS did not influence the performance of the tests applied. Level of Evidence I; Diagnostic studies - Investigation of a diagnostic test.

Background Lumbar spondylolysis in young soccer players has not been studied extensively. Purpose The purpose of this study was to review lumbar spondylolysis in young soccer players, describe the causes, and report the results of nonoperative treatment emphasizing the cessation of activity for 3 months. Study Design Case series; Level of evidence, 4. Methods The authors reviewed 57 child and adolescent soccer players (35 boys and 22 girls) with lumbar spondylolysis who came to their outpatient clinic for back pain evaluation. These patients received different modalities of nonoperative treatment, including cessation of sports and wearing a thoracolumbosacral orthosis. Soccer skills, field position, side of dominant leg, age, initiating event of low back pain, duration of symptoms, and nonoperative treatment were reviewed. Clinical outcome of treatment was assessed by the Steiner-Micheli criteria at the most recent follow-up (minimum 2 years). The Fisher exact test was used to compare all the data. Results Of the patients, 43% noticed that pain started after a high-velocity kick. Thirty-three (58%) of 57 patients had excellent results with no pain during sports, 20 (35%) good, 3 (5%) fair, and 1 (2%) poor. Subjects who ceased playing soccer for 3 months had better results than those who did not comply with this restriction. Conclusion The authors recommend stopping sports for at least 3 months in cases of lumbar spondylolysis in young soccer players who hope to return to their previous level of play without back pain.

Objective: Fifth metatarsal fractures occur mainly in young athletes, with an estimated incidence of 1.8 per 1,000 people a year. The objective of this study was to evaluate the functional outcome of professional soccer players subjected to surgical treatment of fifth metatarsal base fractures. Methods: A total of 34 soccer players who underwent surgery from July 2001 to June 2016 were evaluated. All participants were evaluated by the American Orthopedic Foot and Ankle Score (AOFAS) and visual analogue scale (VAS) score before and after surgery, with a mean follow-up of 23 months. The need for grafting relative to time to surgery, time to fracture consolidation and Torg classification and graft use relative to return to sport were valuated. Results: There were 10 forwards, 7 offensive midfielders, 6 fullbacks, 5 center midfielders, 3 defenders, 2 goalkeepers and 1 defensive midfielder, with a mean age of 19 years. The mean pre- and postoperative AOFAS was 42 and 99 points whereas the mean VAS score was 6 and 0, respectively. The longer the time to surgery, the greater was the need for grafting (p=0.011). The time to return to sport was not influenced by the time to surgery, time to consolidation, Torg classification or graft use. Conclusion: The surgical treatment of fifth metatarsal base fractures in professional soccer players showed good clinical results. The return to activities after surgery is not influenced by the time to surgery, time to consolidation, Torg classification or grafting. Level of Evidence IV; Therapeutic Studies; Case Series.

ABSTRACT Objective: Several studies have already described the main injuries to soccer players during FIFA World Cup events; however, little is known about the main reasons spectators require medical assistance during these matches. The aim of this study is to assess the number of cases and main reasons spectators required medical assistance during the 2014 World Cup matches in Brazil. Methods: Data were collected from spectators who received medical assistance on all game days, and factors related to the assistance provided were analyzed. Results: Medical assistance was given to spectators in a total of 6,222 cases during the 64 games played in Brazil, an average of 97.2 times per game. The total number of spectators removed from the stadiums by ambulance was 167, a mean of 2.6 removals per game. The main reasons spectators required medical assistance during the World Cup games were headache, gastrointestinal problems, and trauma. Conclusions: Most spectators required medical assistance during the World Cup games for headache, gastrointestinal problems, and trauma; this information is fundamental to develop new prevention strategies and plan medical assistance for large-scale events.

The Relationship

Background: Previous studies have examined the relationship between external training load and creatine kinase (CK) response after soccer matches in adults. This study aimed to build training- and match-specific CK prediction models for elite youth national team soccer players. Hypothesis: Training and match load will have different effects on the CK response of elite youth soccer players, and there will be position-specific differences in the most influential external and internal load parameters on the CK response. Study Design: Prospective cohort study. Level of Evidence: Level 4. Methods: Forty-one U16-U17 youth national team soccer players were measured over an 18-month period. Training and match load were monitored with global positioning system devices. Individual CK values were measured from whole blood every morning in training camps. The dataset consisted of 1563 data points. Clustered prediction models were used to examine the relationship between external/internal load and consecutive CK changes. Clusters were built based on the playing position and activity type. The performance of the linear regression models was described by the R2 and the root-mean-square error (RMSE, U/L for CK values). Results: The prediction models fitted similarly during games and training sessions ( R2 = 0.38-0.88 vs 0.6-0.77), but there were large differences based on playing positions. In contrast, the accuracy of the models was better during training sessions (RMSE = 81-135 vs 79-209 U/L). Position-specific differences were also found in the external and internal load parameters, which best explained the CK changes. Conclusion: The relationship between external/internal load parameters and CK changes are position specific and might depend on the type of session (training or match). Morning CK values also contributed to the next day’s CK values. Clinical Relevance: The relationship between position-specific external/internal load and CK changes can be used to individualize postmatch recovery strategies and weekly training periodization with a view to optimize match performance.

Background: The collagen meniscal implant (CMI) is a biologic scaffold aimed at replacing partial meniscal defects. The long-term results of lateral meniscal replacement have never been investigated. Purpose: To document the clinical outcomes and failures of lateral CMI implantation for partial lateral meniscal defect at a minimum 10-year follow-up. Study Design: Case series; Level of evidence, 4, Methods: This study included 24 consecutive patients who underwent lateral CMI implantation for partial lateral meniscal defects between April 2006 and September 2009 and who were part of a previous study with a 2-year follow-up. Outcome measures at the latest follow-up included the Lysholm score, Knee injury and Osteoarthritis Outcome Score, visual analog scale (VAS) for pain, Tegner activity level, and EuroQol 5-Dimensions score. Data regarding complications and failures were collected, and patients were asked about their satisfaction with the procedure. Results: Included in the final analysis were 19 patients (16 male, 3 female) with a mean age at surgery of 37.1 ± 12.6 years and a mean follow-up of 12.4 ± 1.5 years (range, 10-14 years). Five failures (26%) were reported: 1 CMI removal because of implant breakage and 4 joint replacements (2 unicompartmental knee arthroplasties and 2 total knee arthroplasties). The implant survival rate was 96% at 2 years, 85% at 5 years, 85% at 10 years, 77% at 12 years, and 64% at 14 years. Lysholm scores at the final follow-up were rated as “excellent” in 36% (5 of 14 nonfailures), “good” in 43% (6 of 14), and “fair” in 21% (3 of 14). The VAS score was 3.1 ± 3.1, with only 16% (3 of 19 patients) reporting that they were pain-free; the median Tegner score was 3 (interquartile range, 2-5). All clinical scores decreased from the 2-year follow-up; however, with the exception of the Tegner score, they remained significantly higher compared with the preoperative status. Overall, 79% of patients were willing to undergo the same procedure. Conclusion: Lateral CMI implantation for partial lateral meniscal defects provided good long-term results, with a 10-year survival rate of 85% and a 14-year survival rate of 64%. At the final follow-up, 58% of the patients had “good” or “excellent” Lysholm scores. However, there was a general decrease in outcome scores between the short- and the long-term follow-up.

Background: Tendon injuries are commonly seen in sports medicine practice. Many elite players involved in high-impact activities develop patellar tendinopathy (PT) symptoms. Of them, a small percentage will develop refractory PT and need to undergo surgery. In some of these patients, surgery does not resolve these symptoms. Purpose: To report the clinical results in a cohort of athletes who underwent further surgery after failure of primary surgery for PT. Study Design: Case series; Level of evidence, 4. Methods: A total of 22 athletes who had undergone revision surgery for failed surgical management of PT were enrolled in the present study. Symptom severity was assessed through the Victorian Institute of Sport Assessment Scale for Patellar Tendinopathy (VISA-P) upon admission and at the final follow-up. Time to return to training, time to return to competition, and complications were also recorded. Results: The mean age of the athletes was 25.4 years, and the mean symptom duration from the index intervention was 15.3 months. At a mean follow-up of 30.0 ± 4.9 months, the VISA-P score improved 27.8 points ( P < .0001). The patients returned to training within a mean of 9.2 months. Fifteen patients (68.2%) returned to competition within a mean of 11.6 months. Of these 15 patients, a further 2 had decreased their performance, and 2 more had abandoned sports participation by the final follow-up. The overall rate of complications was 18.2%. One patient (4.5%) had a further revision procedure. Conclusion: Revision surgery was feasible and effective in patients in whom PT symptoms persisted after previous surgery for PT, achieving a statistically significant and clinically relevant improvement of the VISA-P score as well as an acceptable rate of return to sport at a follow-up of 30 months.

Background: Morphological changes characteristic of femoroacetabular impingement (FAI) are common in soccer players. However, the clinical relevance of such anatomical variations is still not well-defined. Hypothesis: We hypothesized that high alpha angle values and/or acetabular retroversion index (ARI) are correlated with rotational range of motion (ROM) of the hip and that there are clinical-radiological diferences between the dominant lower limb (DLL) and nondominant lower limb (NDLL) in professional soccer players. Study Design: Cross-sectional. Level of Evidence: Level 3. Methods: A total of 59 male professional soccer players (average age 25.5 years, range 18-38 years) were evaluated in the preseason. As main outcome measures, we evaluated the alpha angle and the ARI and hip IR and ER ROM with radiographic analysis. Results: The measurements taken on DLL and NDLL were compared and a significant difference was found between the sides in the ER ( P = 0.027), where the DLL measures were 1.54° (95% CI, 0.18-2.89) greater than the NDLL. There were no significant differences between the sides in the measures of IR ( P > 0.99), total ROM ( P = 0.07), alpha angle ( P = 0.250), and ARI ( P = 0.079). The correlations between the rotation measurements and the alpha angle in each limb were evaluated and the coefficient values showed no correlation; so also between the ARI and rotation measures. Conclusion: Morphological changes of the femur or acetabulum are not correlated with hip IR and ER ROM in male professional soccer players. ER on the dominant side was greater than on the nondominant side. There was no significant difference in the other measurements between sides. Clinical Relevance: In clinical practice, it is common to attribute loss of hip rotational movement to the presence of FAI. This study shows that anatomical FAI may not have a very strong influence on available hip rotational movement in professional soccer athletes.
