Abstract
The purpose of this research was to review current research findings related to injuries in elite athletes. For the needs of the paper, professional and scientific literature was analyzed from prestigious scientific journals. The types of athletic injuries that occur are dependent on the athletic discipline. The most commonly injured sites in athletes are the front and back muscles of the thigh and in the ankle joint. The results of this study have indicated that the causes of most injuries are due to overstraining and overload syndrome. These causes often arise from training procedures that have been implemented inadequately and usually relate to the volume and intensity of training without the application of injury prevention techniques.
Keywords injuries • athletes • frequency.
Introduction
Professional sport involves exposing the body to great effort and strain, often resulting in a range of sports injuries, which in turn can have a huge impact on athletes' performances in competitions, which can have additional impact on athletes’

serious injury. These injuries can be of many different types and need to be rehabilitated in the correct time frame to avoid additional complications and longer absence from the sports field. Different sports involve different mechanisms and types of injury, while age, sex and other requirements, depending on whether it is a professional, amateur or recreational sport, directly affect the prevalence of injuries (Maffulli, Longo, Gougoulias, Loppini, Denaro, 2010).
In athletic running disciplines, the process of training and competition involves constant periods of stress on the musculoskeletal system that is repetitive. The consequences of this load, which primarily involves the foot as the beginning of the kinetic chain and the action of forces that are several times greater than the body's weight, are athletes' injuries.
Throwing and jumping disciplines involve the creation of maximum force in a short period of time and in these disciplines injury results from stress caused by maximum muscular contractions (Tyflidis, Kipreos, Tripolitsioti, Stergioulas, 2012). The Australian authors who investigated the frequency, distribution and types of muscle- bone injuries, indicate that athletes belong to a
Athletic injuries vary in their degree of damage and, depending on this, can cause different periods of absence from the sports field, including training and competitive events. The incidence of injuries during international athletic competitions is 10% to 14% of the total number of athletes in the world championships (Alonso, Edouard, Fischetto, Adams, Depiesse, Mountjoy, 2012). Due to the la-

rge number of disciplines and participants in athletics when comparisons are made with collective sports, injury research in athletes is much more demanding. It is possibly the reason why fewer studies have been conducted in this area and the data is rather scarce. However, over the last ten years the largest world athletic competitions have been used to monitor the number, type and cause of injuries, as well as the injury mechanism. This tracking is intensified by certain systems and databases (Jacobsson, Timpka, Ekberg, Kowalski, Nilsson, Renström, 2010).
Monitoring the frequency and types of injuries, as well as the risk factors for their emergence, is very important for modelling an adequate preventive strategy in order to reduce the high number of injuries that occur in international athletic competitions (Alonso, Edouard, Fischetto, Adams, Depiesse, Mountjoy, 2012) and improving the quality of the results and increasing the number of healthy elite athletes. The most common cause of injury in athletics, as stated by numerous authors (D'Souza, 1994; Bennell and Crossley, 1996; Alonso, Junge, Renström, Engebretsen, Mountjoy, Dvorak, 2009; Alonso, Tscholl, Engebretsen et al., 2010; Alonso, Edouard, Fischetto et al., 2012) is overstraining and overload syndrome. This syndrome is caused by constant micro traumas over a certain period of time. Reducing the training load can lead to the regeneration of damaged tissue to the previous structural and functional level, if applied in the acute phase of the injury. Later, when injuries become chronic, there is a lack of tissue regeneration (Jacobsson, Timpka, Kowalski et al., 2012). An athlete with a chronic type injury does not have the ability to continuously advance their sporting form and results and this is often the cause of those athletes retiring from active sports. The seasonal variations in the competition schedule may influence the prevalence of injuries on the field (Rekus, Simaškitė, Šakalys, 2016). The aim of this study is to analyse the frequency of elite athletes' injuries that have occurred in the past 20 years.
Method
The descriptive method was used for the development of this paper, which was supported by theoretical analysis and generalization. Primary and secondary sources were combined including local and foreign professional and scientific literature, expert papers, search of Internet domains and electronic journals. During the search into research carried out by local
56
and foreign authors, the following databases were used: PubMed, Medline, Google scholar, DOAJ, KOBSON, Crossref and HINARI. Newspapers in medicine, sports medicine and sports sciences were searched using the words “injuries”, “frequency”, “female athletes” and “male athletes”.
Lower limb injuries
The training and competitive process in athletic running disciplines involves long periods of repetitive stress on the musculoskeletal system, with a foot impact of 1000 to 1200 times per mile registered (Taunton, McKenzie and Clement, 1988), and the recorded action of this force is two to three times greater than the weight of the body (Cavanagh and Lafortune, 1980). As a result of these stresses that are placed on the locomotor system of athletes, the system becomes overused and injuries reoccur most often in the lower limbs. Injuries to the lower limbs are common in athletics and the site of the injury depends on the particular athletic discipline. Marathon runners most often injure their feet, middle- and
According to a number of studies, the most common injuries that athletes encounter are injuries to the muscles in the back and front of the thigh and ankles (Alonso, Jacobsson,Timpka, Ronsen et al., 2015; Alonso, Junge, Renström et al., 2009; Fong, Hong, Chan, Yung, Chan, 2007; Freckleton and Pizzari, 2013; Alonso, Edouard, Fischetto et al., 2012; Malliaropoulos, Papacostas, Kiritsi et al., 2010; Šolaja et al., 2013; Junge, Engebretsen, Mountjoy, Alonso, Renström et al., 2009).
Injuries to back thigh muscles
Some of the most frequent injuries that occur in athletes and footballers are injuries to the muscles in the back of the thigh (Reurink, Tol and de Vos, 2014). Injuries of this type are common in sports that include sprinting, acceleration, deceleration, jumping and rapid changes in direction of movement which can often lead to repeated injuries (Freckleton and Pizzari, 2013). The rate of

surface, the muscles of this region have different functions. They can serve as hip extensors, knee flexors and external rotors of the hip and knee (Malliaropoulos, 2012). Injuries are usually sustained during sprinting and the region of the injury is mainly on the long head of the biceps femoris muscle and usually involves the proximal
In sprinting disciplines, the rapid change in the contraction of the muscles in the back of the thigh from the agonist phase to the antagonist phase is considered to be the moment when the greatest possibility of injuries is present. Loads during running are different for each muscle of the back of the thigh; however, the

Greek authors state that the most commonly injured muscle in athletes are the
It is evident in the literature (Rekus, Simaškaitė, Šakalys, 2016; Alonso, Edouard, Fischetto, Adams, Depiesse, Mountjoy, 2012; Chumanov, Heiderscheit, Thelen, 2011; Malliaropoulos, Papacostas, Kiritsi et al., 2010; Malliaropoulos, Isinkaye, Tsitas, Maffulli, 2011; Schache, Kim, Morgan, Pandy, 2010; Opar, Williams, Shield, 2012; Schache, Dorn, Blanch, Brown, Pandy, 2012; Yeung, Suen, Yeung, 2009; Šolaja et al., 2013) that muscle injuries to the back of the thigh are the most commonly reported by athletes.
A classic mild muscle rupture in this area usually requires three weeks of therapy, while severe forms of injuries can lead to the athlete never returning to the sports field (Kujala, Orava, Jarvinen, 1997). After six weeks the condition of the muscles at the back of the thigh should be checked with an MRI scan, thus giving accurate data that is relevant in the prediction required for the return of athletes to the training process (Askling, Tengvar, Saartok, Thorstensson, 2007).
Ankle Joint Injuries
During sports activities involving the ankle joint or its structures, high forces act and 25% of all athletes' injuries are attributed to injuries to the ankle joint. Also, repeated injuries occur in 70% of cases due to the action generated during movement in combination with the residual joint

commonly caused by running on uneven surfaces and during impact landing usually from an unstable position. Then the entire body movement moves to the anterior talofibular ligament (lig. talofibularis anterior) and can cause strains, partial rupture or total tearing. In the analysis of 70 sport disciplines that have been the subject of a study, athletics appears in 24 sport disciplines, where the most common injury is that of the ankle joint (Fong, Hong, Chan, Yung, Chan, 2007). Among athletes who have frequent jumps in their events, such as high jump and long jump, an increased incidence of this injury has been observed. In the event of an ankle injury, the most common is a grade 2 sprain (Moderate). These types of injuries are more common among professional athletes than those who participate in amateur sports (Marjanović, 2011). During the World Championship in Daegu (South Korea, 2011), 6% of ankle joint injuries were recorded in relation to the total number of injuries. According to the figures, these types of injuries were the third most common, while injuries to the back of the thigh and lower leg injuries
occupied the first two places (Alonso, Edouard, Fischetto et al., 2012). At the 2008 Beijing Olympics, the highest number of injuries recorded was ankle injuries, most common being stretching of the ligaments in the ankle (Junge, Engebretsen, Mountjoy, Alonso, Renström et al., 2009). In their research with elite Serbian athletes, Šolaja et al. registered 24 (13.79%) injuries to the ankle in four years, second only to the most common injuries occurring in the back of the thigh. At the World Championship in Moscow (2013), ankle injuries accounted for 2.1% of the total number of injuries in that competition. However, participants in this competition reported 19 (9.8%) injuries to the ankle joint two months before the World Championship (Alonso, Jacobsson, Timpka, Ronsen et al., 2015). Greek and Spanish authors concluded that there was a statistically significantly higher incidence of injuries to the back side of the thigh in elite athletes who had also experienced earlier injuries to the ankle ligaments (Malliaropoulos, Bikos, Mecca, Vasileios, Valle, Lohrer, Maffulli, Padhiar, 2018).

For this calculation one injury prior to the competition and the first injury suffered during the athletic competition were noted. Information was lacking for 10 athletes, 6 females and 4 males, on injuries before the competition and data on the first injury during the competition by an athlete. This data is excluded from the analysis. The value of the arithmetic mean for upper leg injuries before the competition was 6.0 (3.5), for knee injuries 4.9 (4.3), for lower leg 4.7 (3.4), for injuries of the neck/spine

Injuries to Muscles in the Front of the Thigh
The maximum speed of running is based on certain motor skills. These abilities primarily relate to the frenetic movement and the explosive power of the muscles of the lower extremity extensions (Tončev,
EQOL Journal (2019) 11(2):
2001). Front thigh muscles actively engage with maximum stress in running and jumping and because of this they are often injured. The cause of injuries to this muscular region is often an inadequate amount of training intensity and accordingly leads to constant overstretch and muscle load (Tončev, 2001). The cause of this type of injury, which is manifested by swelling and muscle pain in the front of the thigh, may include, among other things, pelvic injuries, such as an avulsion fracture of the ischial tuberosity (spina iliaca anterior inferior). Such injuries require an operative treatment to enable the full recovery of the athlete. In the rehabilitation process, systematic muscle strengthening is necessary because after the operation, isokinetic muscle testing shows weakness of the extensor musculature in the leg operated on (Milankov, Harhaji, Gojković, Drapšin, 2011). A rupture of the tendon of the
front thigh (28.2%)
In athletics, injuries to the lower limbs are characteristic and the greatest number of injuries is diagnosed in those athletic disciplines where during the whole year the primary load is focused on the lower extremities during the training and competition process, such as in sprints (Rekus, Simaškaitė, Šakalys, 2016). Injuries to the muscles of the inner thigh, the hip flexor muscle, knee, lower leg, Achilles tendon and the feet belong in specific athletic injury groups (Šolaja et al., 2013). They are common and their appearance is registered in major international competitions (D'Souza, 1994; Bennell and Crossley, 1996; Zemper, 2005; Fallon, 1996; Tyflidis, Kipreos, Tripolitsioti, Stergioulas, 2012; Alonso, Edouard, Fischetto, Adams, Depiesse, Mountjoy, 2012; Alonso, Junge, Renström, Engebretsen, Mountjoy, Dvorak, 2009; Alonso, Tscholl, Engebretsen, Mountjoy, Dvorak, Junge, 2010; Jacobsson, Timpka, Kowalski, Nilsson, Ekberg, Renström, 2012; Junge, Engebretsen, Mountjoy, Alonso, Renström et al., 2009, Engebretsen, Soligard, Steffen, Alonso, Aubry et al., 2013; Edouard, Morin, Pruvost, Kerspern, 2011; Rekus, Simaškaitė, Šakalys, 2016).
Injuries to Upper Limbs and Torso
Injuries to the upper limbs are characteristic of the athletic throwing disciplines (Rekus, Simaškaitė, Šakalys, 2016). The lower back - lumbar area around the spine has the greatest load during these types of sports activities. Different activities that are present in the athletic training process, such as weight lifting in power training and the throwing of projectiles such as: javelin, discus, shot put and hammer, the constant torsion and compression of the spine seen during jumping and running can all be the causative agent of acute or chronic back pain. Problems occurring in the lumbar area of athletes who deal with throwing, jumping and sprinting are defined as discogenic, back
muscle injuries, combined injuries, etc. (Malliaropoulos, Bikos, Tsitas, Papadopoulou, 2011). Upper limb injuries are characteristic in throwing disciplines. During the throwing of the projectile, a multiple load is observed in the shoulder joint, which is conditioned by the weight of the projectile and the speed of movement. On the one hand, the shoulder must have sufficient flexibility to allow for excessive external rotation during movement, but on the other hand it has to be stable enough to prevent symptomatic shoulder subluxation (Wilk, Obma,
59

Simpson, Cain, Dugas, Andrews, 2009). Lithuanian researchers who investigated injuries in their top- ranking track and field athletes found that all of the injuries to the upper limbs (12%) were in athletes involved with throwing events (Rekus, Simaškaitė, Šakalys, 2016). If we are talking about a young person, the risk of a
In a study involving 174 top athletes, back injuries amounted to 14.4% of the total number of injuries (De Souza, 1994). In a study by authors from Australia (Bennell and Crossley, 1996), torso injuries, which included back, pelvic and hip injuries, were represented with 13% of the total number of injuries and ranked fourth. The highest number of injuries was recorded in the location of the lower limbs, as follows: the muscle of the front thigh (21.5%), knee (16.2%) and foot (14.6%). In a

In analyzing data received at the World Athletics Championships in Berlin (Germany), 2009, 236 injuries were recorded, with 13% being torso injuries (Alonso, Tscholl, Engebretsen, Mountjoy, Dvorak, Junge, 2010). In four years 19 (10.92%) injuries to the torso and upper limbs were recorded in elite Serbian athletes (Šolaja et al., 2013). While taking part in the World Championships in Moscow, 2013, 14 torso and upper limb injuries occurred. Here the authors
included neck and spine in the injuries of the torso (Alonso, Jacobsson, Timpka, Ronsen et al., 2015).
The study, which included 64 injuries, found that 1.5% of the total number of injuries included upper limbs and injuries to the chest (Fallon, 1996). In all studies that dealt with this problem, the highest percentage of athletic injuries were recorded in the lower limbs

Conclusion
The type of athletic injuries that occur depends most often on the particular athletic discipline. The most frequently injured sites in athletes are the back and front of the thigh and in the ankle joint. The causes of most athletic injuries are described in literature as a result of overstrain and overload syndrome. Inappropriate volume and intensity applied during the training process without the use of specific exercises for the goal of preventing athletes' injuries, results in injuries in athletes. In order to reduce the number of injuries and increase the number of healthy athletes who are then able to achieve top performances in competitions, constant education of athletic coaches is needed along with the cooperation of athletic clubs and selected top sports doctors.
