ABSTRACT Introduction The ankle has the highest incidence of soccer injuries (17 to 20% of injuries), which can cause personal and professional losses for the athlete. Ankle stability is due to a number of mechanisms, such as muscle control between agonists and antagonists, proprioception, balance, and muscle strength. If there are changes in any of these mechanisms, there is an increased risk of ankle injuries. Objective The purpose of this study was to analyze the ankle function of amateur and professional soccer players in the preseason, using Y Balance Test (YBT) and Dorsiflexion Lunge Test (DLT), observing possible functional deficits in this sample, and subsequently analyzing the relationship of results between the functional tests in this population. Methods A total of 107 soccer players were assessed, of whom 36 were amateur and 71 professional athletes. The volunteers initially underwent history taking, followed by a 5-minute warm-up on a stationary bicycle then the YBT and DLT functional tests. Results There was no significant difference in the DLT between dominant and non-dominant limbs in amateur and professional athletes. There was also no significant difference in the YBT between dominant and non-dominant limbs of amateur athletes, but there was a significant difference between dominant and non-dominant limbs in professional athletes. There was no correlation between the tests when the dominant and non-dominant limbs of the sample were analyzed. Conclusion The weak relationship between the functional tests indicates that both tests are recommended for athletes in clinical practice, since they serve as tools to assess different functional deficits. Level of Evidence III - Case-control study.

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.

ABSTRACT Objective: To evaluate and collect epidemiological data on injuries of the anterior cruciate ligament of the knee in professional soccer players of the Brazilian Championship. Methods: Transversal study, with information extracted from the online data platform www.transfermrkt.com.br (Transfermarkt GmbH & Co. KG), with 5 seasons (2015 - 2019) of the Brazilian championship series A and B being analyzed and revised by 3 researchers. Results: 52 injuries of the anterior cruciate ligament were detected, with a mean age of 26,3 years, time off due to injury of 244.5 ±31.6 days, regardless of the division. Forwarders and defenders had the highest incidences of injury without statistically significant difference, but they had greater chances than goalkeepers, left/right backs and midfielders. Conclusion: The incidence of injury to the anterior cruciate ligament of the knee in professional football players in the first and second divisions of the Brazilian soccer championship between 2015 and 2019 is 0.414 per 1,000 hours of play, a value similar to described in the literature. The incidence of the injury varies according to the player’s field position, being the forwarders and defenders the most injured players. Level of Evidence II, Retrospective study.

Background: Etiologically, the risk of an ankle injury depends on extrinsic and intrinsic factors, such as muscle strength asymmetry, decreased flexibility, and decreased proprioception, as well as patient age and history of injuries. Purpose/Hypothesis: The purpose of this study was to identify risk factors present in the preseason assessment that may predispose professional soccer players to ankle injuries. We hypothesized that analysis of these parameters could relate the incidence of injuries to the deficits found during the preseason period, enabling the identification of risk factors to predict the occurrence of injuries. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 89 professional soccer athletes were evaluated in the preseason period; the evaluation included athlete history and anthropometric data collection, an isokinetic ankle evaluation, and functional tests: the Dorsiflexion Lunge Test and Y-Balance Test (YBT). The athletes were monitored during the competitive period, and the incidence of injuries was surveyed. The association of quantitative variables and injury outcomes was analyzed using the Student t test for independent samples, with P < .05. For the association of categorical variables and injury outcomes, the chi-square test was performed, with P < .05. Results: A higher incidence of ankle injuries was associated with lower YBT scores in the dominant ( P = .04) and nondominant ( P = .01) limbs. A higher body mass index was also associated with a higher injury occurrence ( P = .01). Conclusion: Functional tests, such as the YBT, are indicated tools for assessing the physical capacities and possible risks of ankle sprains, as they can evaluate the ankle functional capacity in a complex way, identifying athletes more prone to ankle injuries. Athletes’ body mass index should also be taken into account to prevent such injuries.

ABSTRACT Introduction: Isokinetics is a tool commonly used in professional soccer. There is ongoing debate among researchers as to the isokinetic reference values a player should have. Objectives: To determine the absolute peak torque (PT) and average work of professional soccer players in relation to their positions on the field, and to establish the reference values for these variables. Methods: Purposeful sampling was used to select 289 professional soccer players. The sample included 32 goalkeepers, 100 defenders, 98 midfielders, and 59 strikers. The participants were measured preseason. The players were asked to perform a 10-minute warm-up on an exercise bike, and then to perform 5 repetitions at low speed, 10 at medium speed, and 25 at high speed, with 30 to 40-s of rest between each set of repetitions. The contraction method was concentric-concentric in a dynamometer Isomed 2000. Results: The average age, weight, and height of the players was 21.9 years, 74.3 kilograms, and 1.8 meters, respectively. The goalkeepers presented higher PT at the 3 measured speeds, and the higher average work at 180°/s and 240°/s in relation to defenders and midfielders. The strikers presented higher average work at 240°/s in relation to midfielders, and higher PT in relation to the defenders and midfielders. Absolute values were shown and reference values were established. Conclusions: The goalkeepers and strikers were the players that showed the greatest differences in their favor in relation to the other positions. The peak torque values and average work were described in relation to the player's position on the field. This study resulted in the creation of a tool for health professionals working with professional soccer players, providing reference values for these players in relation to their position on the field that can be used as benchmarks, by health professionals, to optimize soccer players’ performance.

Background: Musculoskeletal hip/groin screening tests are commonly performed to detect at-risk individuals. Bony hip morphology is considered a potential intrinsic risk factor but has not been examined prospectively. Purpose: To evaluate the association between intrinsic risk factors identified from musculoskeletal and radiographic screening tests and hip/groin injuries leading to time loss from training and/or match play in professional male soccer players. Study Design: Prospective cohort study; Level of evidence, 2. Methods: Male professional soccer players, aged ≥18 years, underwent screening specific for hip/groin pain during 2 consecutive seasons of the Qatar Stars League. The screening battery included pain provocation, range of motion, and strength tests as well as a hip radiographic examination. The radiographic examination included an anteroposterior pelvic view and 45° Dunn view, with bony hip morphology determined using quantitative methods. Time-loss (≥1 day) hip/groin injuries and individual player exposure (training and match play) were recorded prospectively, and injuries were categorized as adductor-related, inguinal-related, iliopsoas-related, pubic-related, or hip-related groin pain, or “other,” as recommended in the Doha agreement. We calculated hazard ratios (HRs) from univariate and multivariate Cox regression models to assess the relationship between potential risk factors and hip/groin injuries. Results: There were 438 players, completing 609 player seasons, and 113 hip/groin injuries that met the criteria for inclusion, with 85 injuries categorized as adductor-related. The proportion of players with bony morphological variants was the following: cam, 71%; pincer, 5%; and acetabular dysplasia, 13%. Previous hip/groin injuries (HR, 1.8; 95% CI, 1.2-2.7) and eccentric adduction strength were associated with the risk of hip/groin injuries. Higher (>1 SD above the mean) than normal eccentric adduction strength was associated with an increased risk for all hip/groin injuries (HR, 1.6; 95% CI, 1.0-2.5). Lower (<1 SD below the mean) than normal eccentric adduction strength was associated with an increased risk for adductor-related injuries (HR, 1.7; 95% CI, 1.0-3.0). No other musculoskeletal screening test or bony hip morphology variables were associated with the injury risk. Conclusion: Previous groin injuries and eccentric adduction strength were associated with the risk of groin injuries. However, these associations were not strong enough to identify an “at-risk” individual, and therefore, musculoskeletal screening tests were not useful to dictate individualized prevention strategies. Bony hip morphology was not associated with the risk of groin injuries.

Abstract Background and objective Soccer is associated with repetitive head trauma, which, as it is known from sports like football and boxing, can result in hypopituitarism. Gonadotropins and GH are the most common pituitary hormones to become deficient. GH deficiency is associated with an increased risk of cardiovascular mortality and has negative influence on body mass index, visceral fat mass, insulin resistance and sensitivity, bone mineral density and inflammatory markers. Therefore the aim of this study was to evaluate the somatotrope pituitary function in professional soccer players. Research design and methods This clinical study included 15 male, professional soccer players with at least 10 years of professional training. Basal hormonal parameters of the pituitary axis were obtained from the participants. To assess GH-IGF-I axis, glucagon stimulation tests were used. Rise in growth hormone during glucagon test was analyzed and the prevalence of newly diagnosed hormone deficiencies was evaluated. Results Mean age of all participants was 31±10 years. None of the 15 soccer players had GH deficiency. Mean rising factor of GH after stimulation with glucagon was 100 in all participants. We did not find signs of ACTH, TSH or LH/FSH deficiency in any player. Conclusions In this small collective of soccer players we did not find playing soccer to be a risk factor for the development of GH-deficiency. According to our data screening for somatotrope deficiency is not necessary. Further investigations in larger cohorts are needed.

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.

The Stability

Stability plays a key role in the sport competition in football. Synchronized operation stabilization of the lower limb and trunk of the support with the dynamic movement of the contralateral limbs allow you to perform tasks specific to the discipline, eg. variety kicking of the ball. Purpose. The aim of the study was to evaluate differences in the capabilities to maintain postural stability in standing on one leg dominant and non-dominant leg with professional players including grouping variables: age, height, weight, volume of training aimed at improving the stability and general internship of football player career. Although commonly assumed that the non-dominant leg is predisposed to act more effective support for the body, the work to date have failed to identify indicated differentiation. It should be noted, however, that they were carried out on small trials in people less active, or among amateur athletes. Basic procedures. The study involved 31 professional soccer players from 1 to 5 level of division. In order to assess postural stability, each of the test performed three times a standard stability test consisting of three 20-second attempt to maintain balance on one leg becoming dominant and non-dominant leg on stabilometric platform BIODEX Balance System. For each of the lower limbs test was repeated three times. Assessment were average angular range deflections platform in the two reference planes, and the volatility of these deflections. These parameters were treated as a measure of postural stability of the respondents. Main findings. In the whole group of patients, no statistically significant differences in the possibilities to maintain postural stability in standing on one leg dominant and non-dominant leg. No significant differences were also detected when considering grouping variables. Conclusions. The results do not indicate a significant difference in the ability to maintain postural stability in standing on one leg dominant and non-dominant leg in professional soccer players.

Study Design: Prospective study, simple crossover design. Background: Proprioception is a cornerstone for maintaining joint and postural stability. Dynamic stability is particularly emphasized within these components. This feature is important in the rehabilitation field. Therefore, the quest for elements to improve these values ​​can bring advantages in sports. Objectives: Evaluate if there are advantages in the performance of a Star Excursion Balance Test (SEBT) using Kinesio taping. Methods: We evaluated 10 professional soccer players from the Chilean women’s national team. They were randomly divided into 2 groups. One group had Kinesio taping and their SEBT performance was evaluated. The other group performed the measurements without the use of Kinesio Taping. Afterward, each group performed the evaluation they did not do during the first stage. We then compared the performance achieved with and without the use of Kinesio Taping Results: There were significant differences in the performance achieved by the players who had the SEBT bandage applied in comparison to the players that did no. This was confirmed by using the non-parametric Wilcox test for each of the SEBT positions. Conclusions: Kinesio taping has positive implications in the SEBT. We can extrapolate that its use can improve the dynamic balance and thus become an important pillar in sports rehabilitation.

Football is a functional sport requires speed, endurance, combinability and many others specific skills. In order to evaluate physical condition of professional football players different medical, sports and pedagogical, and functional tests are applied. Tests with loading are used for assessment of physical working capacity and the adaptation to physical loading. Spiroergometry tests give additional information about the condition of cardiovascular system and the aerobic capacity of the sportsmen.The aim of the study was to analyze results from spiroergometry tests of professional soccer players in Bulgaria.A group of 26 healthy professional soccer players, age 18-25 years, voluntary underwent spiroergometry test with veloergometer, with stepwise incremental physical loading on system AT-104 (Schiller, Switzerland). During investigation the heat rate (b. p. m.), levels of the systolic and the diastolic arterial blood pressure (mmHg), oxygen consumption (VO2, l/min), the volume of exhaled carbon dioxide (VCO2, l/min), and other functional indices were monitored. After the termination of each test the subject remains on the veloergometer for five minutes with 10% of the peak loading in order to recover the heart rate, levels of the arterial blood pressure, breathing rate etc. The anaerobic threshold (AT, calculated by VE/VCO2 slope method) and the heart rate recovery after physical loading were terminaed using software. The results of the tests were divided in two groups – the test was terminaed at the subject’s request (N, 15 tests), and test terminated at hypertonic blood pressure reaction (HR, 8 tests). Three tests were terminated at other medical indications. Results were presented as X±SD. An independent samples t test was used (SPSS, v. 13).Surprising 42% of the tests in present study were terminated at medical indications. The major reason for medical termination of the test was hypertonic blood pressure reaction - 72%. There were no differences in the body mass index between the groups. The loading at the range of the AT, heart rate at AT and blood pressure at the level of the AT between the groups were without significant differences. The recovery period was normal in both groups. VO2, the heart rate, levels of the systolic and the diastolic blood pressure at the different levels of physical loading were similar in group N and HR. We found out lower age of group N as compared with group HR (20.36±1.63 vs. 22.63±4.37 years, P<0.05), and higher maximal levels of the systolic and the diastolic blood pressure in HR (P<0.05).Regardless of the good physical condition of the professional soccer players 42% of the tests in the study were terminated at medical indications. Despite the little difference in the age between the groups it was significant. The basic functional indices were similar in each step of physical loading. Diseases were not found in the participants. Results of our study confirm necessary of applying functional tests. The data pay attention at the influence of the age and quality medical care in professional sport.
