Background/aimFootball players frequently face the occurrence of non-contact musculoskeletal injuries. The purpose of the study was to verify whether the evaluation of combined risk factors could produce a score system to determine the probability of injury in football players during the Brazilian football season.MethodsSixty-two male professional soccer players recruited from the first and second division soccer teams, with ages between 18 and 36 years. Functional performance evaluations were carried out at the beginning of the preseason which included strength and jumping tests, history of injuries and characteristics of athletes.Results and conclusionsThe results were grouped and a score/monogram was constructed.

The aim of this study was to examine whether match physical output can be predicted from the workload applied in training by professional soccer players. Training and match load records from two professional soccer teams belonging to the Spanish First and Second Division were collected through GPS technology over a season ( N = 1678 and N = 2441 records, respectively). The factors playing position, season period, quality of opposition, category and playing formation were considered into the analysis. The level of significance was set at p ≤ .05. The prediction models yielded a conditional R-squared in match of 0.51 in total distance (TD); 0.58 in high-intensity distance (HIRD, from 14 to 24 km · h−1); and 0.60 in sprint distance (SPD, >24 km·h−1). The main finding of this study was that the physical output of players in the match was predicted from the training-load performed during the previous training week. The training-TD negatively affected the match physical output while the training-HIRD showed a positive effect. Moreover, the contextual factors – playing position, season period, division and quality of opposition – affected the players’ physical output in the match. Therefore, these results suggest the appropriateness of programming lower training volume but increasing the intensity of the activity throughout the weekly microcycle, and considering contextual factors within the load programming.

Background and Study Aim. The aerobic fitness in soccer is an important performance component. The aerobic endurance level of players may positively effect performance of critical match activities. The examination of Yo-Yo intermittent recovery test (YYIRT) performance of young soccer players at different playing positions was aimed in this study. Material and Methods. The research group was consisted of 75 young soccer players playing at U-21 category of professional soccer teams at different leagues. The soccer players at 5 different playing positions participated in study voluntarily (centerback: n=15, fullback: midfielder: n=15, winger: n=15, forward: n=15). The YYIRT (level 1) was performed for determination aerobic endurance parameters (covered distance during test, maximum oxygen uptake (VO2max) and maximal aerobic speed (MAS) of players. The one-way ANOVA analysis was used for comparison between playing positions of YYIRT parameters. Results. It was determined that difference between YYIRT parameters of players at different playing positions was non-significant (p>0.05). However, the midfielders covered more distance (2425,33±440,42 m) than forward (2146,67±339,64 m), winger (2137,33±615,18 m), fullback (2056,00±512,43 m) and centerback (1960,00±313,51 m) players. The positional requirements of midfielders may be decisive on covered distance during YYIRT. Conclusions. Consequently, it may be said that the young soccer players at different playing positions had similar YYIRT performance and the playing position effect on YYIRT performance could vary depending on league level and individual features of players.

Purpose. To find risk factors for soccer-related musculoskeletal injuries among elite, adolescent male soccer players. Methods. Prior to the season, various physical, clinical, and functional measurements were taken. One season was used as an injury surveillance period. Then, after the season, measures of potential risk factors were compared between (1) those players who sustained musculoskeletal injuries and (2) those who remained injury free. Results. Among 61 players, 37.7% (23/61) sustained soccer-related musculoskeletal injuries. After adjusting for covariates in a logistic regression model, presence of previous hip and low back injury (adjusted odds ratio [aOR] = 8.93, P = .046) and Functional Movement Screen (FMS) scores (aOR = 1.92, P = .022) were independently associated with musculoskeletal injures. Conclusion. Elite, adolescent male soccer players with a history of hip and back injury are at greater risk of sustaining a soccer-related musculoskeletal injury. In addition, our study indicated greater risk of sustaining a future soccer-related injury as FMS scores increase.

Psychological Predictors of Injury among Professional Soccer Players Objectives: Numerous empirical studies suggest that specific psychological factors influence the frequency and severity of sport injuries. The main purpose of the present study is to outline the psychological factors, which predict increased injury vulnerability among professional male soccer players in Denmark. Based on the Stress-Injury Model by Williams & Anderson (1998) it is hypothesized that low coping resources, high competitive trait anxiety, and history of previous injuries would be positively related to an increased risk of injury occurrence and severity. Methods: The soccer players (N = 87) were asked to report history of previous injuries within the last 12 months. Furthermore, 2 questionnaires were used; Competitive Trait Anxiety Test, and Athletic Coping Skills Inventory - 28 (ACSI-28). Injuries were prospectively recorded throughout a period of approximately 3 months by the team's medical staff (doctors and physiotherapists). Results: Study findings clearly suggest that history of previous injury and coping with adversity are the best predictors of injury occurrence. These factors explained between 7 % and 11 % of the total variance of injury occurrence and days lost due to injury respectively. Furthermore, the same variables were found very successful in prediction injury occurrence. Conclusions: The findings support the suggestions that psychological factors can be utilized as a predictive measurement to sport injuries, which should be considered by coaches and medical staff in order to reduce vulnerability to injury.

Objective: To evaluate the maximum oxygen consumption (VO2max) and the Maximum Aerobic Speed (MAS) with direct and portable measurement in field, in professional soccer players using the UNCa test. Material and method: 9 professional soccer players (age: 26.8±5.12 years, mass: 78.7±5.8 kg, height: 177.3±5.8 cm), belonging to the first and promotion categories of AFA soccer league, were measured in the field with the UNCa test using direct gas measurement. A subsample of 3 players was also measured on treadmill. On treadmill and in the field, the same Medgraphics® VO2000 gas analyzer was used. Results: In the field, a VO2max of 52.18±5.86 ml/kg/min, and a MAS of 14.8±1.3 km/h were found. Also, a correlation between VO2max and MAS of r = 0.75, and between MAS and the final speed reached (FSR) r=0.91. In the subsample, no differences were found between treadmill and field in VO2max; 46.6±1.4 ml/kg/min and 48.1±2.2 ml/kg/min (p <0.001) respectively. Differences between MAS are shown; 17.0±0.0 km/h for the treadmill and 13.7±1.5 km/h for the field (p <0.001) replicating the protocol. Conclusion: If professional players of the Argentine Football Association (AFA) were measured directly and in the field, applying the UNCa test for the first time. The VO2max and MAS values were slightly lower than those published in the bibliography
