Aim To study the association between player characteristics, technical components of the game and the risk of match injuries during the 2017 Men’s Handball World Championship.

Methods Team physicians of the participating teams (n=24) were requested to provide injury report forms throughout the Men’s Handball World Championship (France, January 2017). The individual time played, age, number of international matches played and all technical and penalty variables for each player were extracted from the official International Handball Federation (IHF) online database and used as risk factors in a general logistic linear model analysis.

Results Of 387 players, 49 sustained one or more injuries (93 injuries in total). The total incidence of match injuries was 82.1 injuries per 1000 hours (95% CI 66.2 to 100.5), non-time-loss injury incidence was 40.6 injuries per 1000 hours (95% CI 29.3 to 54.9), while time-loss injury incidence was 30.9 injuries per 1000 hours (95% CI 21.5 to 42.9). Multivariate analysis showed that age (OR 1.1, 95% CI 1.02 to 1.18, p=0.011), player position (backs: OR 6.79, 95% CI 2.25 to 20.54, p=0.001; goalkeepers: OR 5.03, 95% CI 1.15 to 21.94, p=0.031) and 2 min suspensions (1–2 times: OR 2.77, 95% CI 1.27 to 6.04, p=0.011; 3 or more times: OR 2.66, 95% CI 1.18 to 6.38, p=0.029) were significant risk factors for getting injured during competition matches.

Conclusion Age, player position (backs, goalkeepers) and 2 min suspensions were associated with match injury. Stricter rule enforcement should be considered to prevent match injuries in elite handball.

What are the findings?

  • Older players were at greater risk of match injury.

  • Players sanctioned with 2 min suspensions were approximately three times (one to two times: OR 2.77 and three or more times: OR 2.66) more likely to sustain an injury compared with players remaining suspension-free.

  • Back players were at approximately seven times greater risk of injury compared with wing players.

How might it impact on clinical practice in the future?

  • Handball coaches and medical staff should consider focusing on ways/techniques to reduce injury risk by recommending their players to decrease 2 min suspensions.

  • The IHF has already advised referees to heavily sanction fouls against attacks from the wing, and it seems reasonable to consider what can be done to protect the back positions in a similar way.


Handball is a modern Olympic sport played by two competing teams of seven players on an indoor court over two halves of 30 min. Matches are characterised by repeated bouts of high-intensity activity with frequent contacts and collisions between players1 2 resulting in handball being one of the Olympic team sports with the highest risk of injury over the last four summer Olympic games.3–6 For instance, during the 2012 Olympic games, handball had the fourth highest injury score (22%) after taekwondo, football and BMX (39%, 35% and 31% of registered athletes were injured, respectively).3

Descriptive analysis of the injury pattern alone is insufficient to develop preventive measures.7 Studying risk factors of specific-sport injuries is necessary to provide a better understanding of the injury mechanism8 and therefore develop effective injury-prevention strategies.1 Despite some studies have identified that previous injury1 9 and lack of proprioception9 are risk factors for handball-related injuries, prospective studies aiming at investigating the risk factors of handball injuries are limited. According to Hopkins et al,10 player characteristics and behaviours (eg, age, skill, playing position and game strategies) are the most relevant risk factors.

In recent years, match analysis has become an important tool in team sports to gain a deeper insight into the technical, tactical and physiological demands of the game.11 12 This methodological approach is used to quantify the mode and frequency of discrete activities performed during the match.13 Consequently, using the match analysis outcomes in order to associate player characteristics and behaviours with injuries, could enable better understanding of the factors associated with match injuries in handball and thereby guide prevention strategies at the elite level.14 15 Thus, the aims of this investigation were to describe the pattern of injuries during matches of the 2017 Men’s Handball World Championship (the Tournament) and to study the association between player characteristics and the technical components of the game with the risk of match injuries during the tournament.


The methodology and procedures of this study were established based on the IOC injury and illness surveillance protocol,3 6 16 17 using methodology adapted for handball as described in detail by Bere et al.18

Injury data collection

Team medical staff agreed to participate in the study during the first official team medical meeting of the event, held in Paris 2 days prior to the first match.

Team physicians of the participating teams (n=24) and chief physicians of each of the tournament sites were both requested to provide separate injury report forms for each match of the Men’s Handball World Championship (France, 11–29 January 2017). They were asked to complete and submit, for each single match, a standardised one-page report form with predetermined categories, definitions and codes,18 regardless of whether or not any injury had occurred. The report form with definitions and categories was available in six languages (English, Arabic, French, Spanish, German and Russian), so there should be no language barrier to completion of the forms by team medical staff.

The team injury report form was submitted immediately after the match by each team’s medical staff to the chief physician of the site at which the match was played (there were five competition sites in total).

The chief physician was required to submit both the team injury reports and the local organising medical committee injury report forms (by 11:00 hours the following day) to the chief medical officer of the tournament. The team injury report forms could therefore be crosschecked with the injury reports from the local medical teams.

Definition of injury

An injury was defined as ’any musculoskeletal complaint newly incurred due to competition and/or training during the tournament that received medical attention regardless of the consequences with respect to absence from competition or training'. This injury definition includes five aspects: (1) all injuries that received medical attention (those that resulted in time-loss or reduced performance), (2) newly incurred (exclusion of pre-existing and not fully rehabilitated injuries), (3) injuries occurring in competition or training, (4) injuries occurring during the period of the tournament and (5) exclusion of illnesses and diseases.

For each injury, the reporting form included information about injury location, type, cause (ie, contact between players, contact with objects, non-contact trauma, overuse injuries, violation of rules and other), whether or not the player returned to the game just after the injury as well as injury severity (ie, 1–2 days, 3 days–4 weeks or >4 weeks) reported as the time to return to play. The team’s medical staff was required to update any missing date of return to play by informing the chief physician of the site about the date of return to play of the injured player. If players did not return before the end of the competition, the staff were asked to provide an estimated date.

As the aim of the current article was to study the association between performance characteristics of players and their risk of injury during matches, training injuries were excluded and only match injuries were presented and used in the analysis.

Exposure and technical data

The age, time spent on court for each match during the present tournament and the total number of international matches played in the career (before the start of the tournament) of each player were extracted from the official IHF online database.19 In addition, player position, the number of shots and the offensive, defensive and penalties variables (ie, 2 min suspensions, red and yellow cards) during the present tournament were extracted from the same website (table 1).19

Table 1

Description of player characteristics, technical and penalties variables used in the analysis

The data were extracted to an Excel file where each player was characterised by each of the variables presented in table 1. The primary outcome for the risk factor analysis was injured (yes or no). Data from matches for which there was no team medical staff injury report form were excluded from the extracted database.

Data management and statistical analysis

The data were analysed using SPSS software (IBM-SPSS statistics, V.23, Chicago, Illinois, USA) and analysed for normality using the Shapiro-Wilk test. Player characteristics and technical variables are presented as mean values (±SD) and we used analysis of variance to compare these variables according to player position.

The number of 2 min suspensions was not normally distributed. Therefore, as per the distribution of the data, this variable was categorised into three groups: (i) no suspension, (ii) one to two suspensions and (iii) three or more suspensions. The red and yellow cards variable was grouped into two categories (yes or no).

A general logistic linear model was used to analyse the association between the potential risk factor variables and injury outcome. First, the relationship between each of the candidate risk factor variables and injuries was analysed in a univariate model. Variables with a p value of <0.2 in the univariate model were thereafter included in a multiple regression model. The potential predictive variables were also checked for multicollinearity and the variable with the highest association with injuries was included in the multiple regression analysis. Regression coefficients are presented as ORs with 95% CIs and the model was adjusted for individual exposure. P values <0.05 were considered as statistically significant.


Injury patterns

There were 83 matches in the tournament. We received 156 of 166 potential daily report forms, corresponding to a total response rate of 94%. In total, 93 injuries were reported. Of the 387 accredited players included in this study, 49 players sustained one or more injuries, meaning that 12.6% of the players suffered at least one injury during the tournament.

The total effective playing time of the players was 1133 hours. A significant difference in exposure was found between non-injured (n=338; mean: 2.9±1.6 hours) and injured (n=49; mean=3.5±1.6 hours) players (p=0.01; mean difference: 0.6; 95% CI 0.1 to 1.1).

Out of the total injuries, 42 were non-time-loss injuries (45.2%), while there were 35 time-loss injuries (37.6%). In 16 cases (17.2%), information on injury severity was missing.

The total incidence of match injuries was 82.1 per 1000 hours (95% CI 66.2 to 100.5). The incidence of non-time-loss injuries was 40.6 per 1000 hours (95% CI 29.3 to 54.9), while that of time-loss injuries was 30.9 injuries per 1000 hours (95% CI 21.5 to 42.9).

Of the 35 time-loss injuries, 68.6% (n=24) were mild (1–2 days loss), and 22.9% (n=8) moderate (3 days to 4 weeks loss). Three severe injuries (8.5%; two knee injuries and one ankle injury) were reported (leading to an expected absence of >4 weeks).

The body parts most commonly injured were the ankle (19.3%), head/face (17.3%), knee (15.1%) and thigh (12.9%) (table 2). The most common injury types were contusions (46.2%, n=43), followed by sprains (30%, n=26) and strains (10.1%, n=10).

In total, 45.3% (n=42) of all injuries resulted from contact between players, 11.8% (n=11) from contact with objects, 10.8% (n=10) were as a result of non-contact trauma (sudden onset), 26.9% (n=25) were overuse injuries (gradual onset) and 3.2% (n=3) from other causes (ie, violation of rules and other).

Game analysis and penalties

As shown in table 3, back and wing players made more shot attempts than line players, while 6 m shots and fast-break shots were more often taken by line players. Back players led in 9 m shots, breakthrough shots, assists and turnovers.

Risk factor analysis

There was no significant difference between injured and non-injured players regarding the number of total shots attempted (6 m shots, 9 m shots, 7 m shots, fast-break shots, breakthroughs, turnovers, steals, blocked shots) or the rate of 2 min suspensions (number of suspensions per minute).

After univariate analyses examining the relationship between player characteristics and game analysis variables with injury risk (table 5), six candidate variables were included in a multiple logistic regression model (age, player position, wing shots, number of assists, number of 2 min suspensions and red cards). After a manual backward stepwise regression analysis, three variables (age, player position and 2 min suspensions) were retained in the final model and were independently associated with injuries (table 6).

No previous studies have tested the association between player characteristics, the technical components of the game and the risk of match injuries in high-level handball competition. Therefore, this study contributes to the handball injury literature as senior male handball competition injury risk factors are largely unknown. Based on the analyses of this study, age, player position and 2 min suspensions were associated with injury during the 2017 Men’s World Handball Championship.


Despite the fact that greater age has been identified by a number of investigators as an independent risk factor for several types of injury in many sports,20–26 no previous studies have investigated this finding in handball. Our findings demonstrate that older players were at higher risk of getting injured during competition compared with their younger counterparts. In this context, Moller et al 1 have reported that, for male senior, under-18 and under-16 players, the estimated match injury incidence was 23.5 (95% CI 17.8 to 30.4), 17.2 (95% CI 9.3 to 28.8) and 11.1 per 1000 match hours (95% CI 7.0 to 16.6), respectively. Unfortunately, the latter results cannot be directly compared with our findings, as in the present study there was a mix of players with different ages participating in the tournament. Such a finding, however, highlights the need to compare different age groups of senior players competing in the same event.

Player position

In the present study, player position was associated with injury risk. More precisely, back players were at approximately seven times greater risk of injury compared with wing players. In agreement with a previous study, back players in a female European handball team had an injury incidence of 54.8 injuries per 1000 hours, which was 2.3 times higher than wing players, who had the lowest incidence (23.6 injuries per 1000 hours) of the various playing positions.9 Moreover, a recent study showed that the majority of injuries occurred during attacking, with back players being the most vulnerable.

Not all studies agree on susceptibility to injury by position, however, as in the present study wing players had the lowest injury rate (19.9 injuries per 1000 hours), while in another study18 wings had a higher injury incidence than goalkeepers and backs (93.0 to 53.9 and 88.0 injuries per 1000 hours, respectively) and Giroto et al 8 reported that male goalkeepers had a lower incidence of injuries compared with other playing positions.

The low injury risk of wing players may be explained by the fact that wing players perform significantly more wing shots and fast breaks, and are consequently less exposed to physical confrontations compared with back players (table 3),12 as handball rules are very strict relating to wing shots and require that the referees penalise any foul on a player shooting from the wing with a 7 m throw and/or a 2 min suspension.27

Technical actions

Interestingly, in the present study, the number of assists was significantly greater for back players compared with wing players. This is an important consideration, as the univariate analysis indicated that the number of assists, which is a typical offensive action, may be a potential risk factor of injury (table 5). This finding is consistent with previous studies showing that more injuries occur while attacking than defending in the central positions of the field,1 28 29 meaning that players who participate more actively in goal-scoring attempts are at greater risk.1 18 In addition, based on systematic video analysis of injuries occurring during the 2015 Handball World Championship, Andersson et al 29 observed that the match referees were too lenient in their rule interpretation and suggested that stricter application of the rules (and potentially modifying some rules) could reduce the risk of acute match injuries, especially when an attacker performing a jump shot is tackled.

Player suspensions

The regression model (table 6) also highlights that there was an association between 2 min suspension and injury rate. Usually, these types of suspensions are given to more aggressive players who are more likely to come into physical contact with opponents and thus receive most often 2 min suspension.27 Nevertheless, the results of the present study showed that the risk was almost the same regardless of whether the player had one 2 min suspension or more than three. Indeed, during a tournament with six to nine matches, if a player receives only one 2 min suspension, that could be due to lots of different reasons other than the player’s playing style (eg, a certain opponent, a certain referee or just bad luck). However, if a player receives three to four suspensions, then probably that is not just because of the reasons mentioned above, but more likely due to the playing style (ie, playing more aggressive). Therefore, the association between 2 min suspensions and injury is not necessary due to playing style. It could also be explained by the fact that the majority of injuries to defenders occur when they come into contact with the knee/throwing arm (elbow/hand) of an attacker performing a shot with also some of the injuries caused by the ball hitting the defenders.29

Methodological considerations

We acknowledge that the current study was exploratory, not hypothesis-driven and a large number of candidate risk factor variables were explored in the univariate analyses. Therefore, whether there is a causal relationship between player characteristics, the technical components of the game and the risk of match injuries must be interpreted with caution.

The IOC injury and illness surveillance protocol was successfully implemented during the event with a response rate of 94.0%, which is similar to the response rate (96.7%) of the 24th Men’s Handball World Championship 2015 in Qatar. One challenge was that the Handball World Championship in France was played in several different cities, in contrast to the Handball World Championship in Qatar, where all matches were played in one city. As we did not include technical data from matches with missing injury data in the analyses, these are unlikely to bias the outcome of the study. However, it is difficult to ensure whether all medical teams followed the same reporting standard, so differences in how the definitions of injury and their respective categories and codes were interpreted, may have influenced the results.

The exposure data were not obtained directly by the authors, but were extracted from the IHF website. As per IHF procedures, exposure was measured to the nearest second, which implies that the measurement standards used by tournament staff were rigorous.

Murphy et al 30 pointed out that one of the most important limitations in risk factor studies is the relatively small number of subjects and injuries included. In fact, in order to detect ‘moderate’ to ‘strong’ associations, 20–50 injury cases are needed, whereas ‘small’-to-‘moderate’ associations would need about 200 injured subjects.31 The present study, which included 49 injured players out of the 387 players included, was therefore only powered to detect strong and moderate associations.31

Logically, contact injuries are more susceptible to be related to playing style than non-contact ones. However, players who are most involved in the game (by performing more actions including shooting), are also more exposed to overuse injuries. In this context, due to the relatively limited number of match injuries, we included both contact and non-contact injuries in the data set in order not to lose statistical power. Further studies with a larger sample size are needed to analyse contact and overuse injuries separately.

Practical implications and conclusions

Previous studies, in other sports32 33 as well as in handball29 have suggested that stricter rule enforcement should be seriously considered in order to reduce the rate of injuries; however, we do not know how realistic it is for players to modify their playing style. Indeed, reducing aggressive play could result in an impaired performance. Even though the IHF already advises referees to heavily sanction fouls on goal-scoring attempts by wing players, it seems that more strict sanctions could also be considered for the back positions. Further research could explore whether changing strategies/tactics to perform more attacks from the wing leads to a reduction in injures, and what effect this has on team performance.
