Preventive training can modify the neuromuscular risk factors associated with the danger of this injury in women athletes. Determining their characteristics (duration, frequency, type of exercise, etc.) and components (strength, plyometrics, balance, etc.) is critical when designing specific and individualised training for players. The objectives of this study were to identify and categorise the common components of preventive training programmes for anterior cruciate ligament injury in women handball players and to describe and classify the exercises involved in each category. A systematic review was conducted following the guidelines of the PRISMA Statement in the Web of Science, Sport Discus, PubMed, Scopus, Cochrane and ScienceDirect databases. The inclusion criteria were: (a) participants were female handball players of any age, (b) there was a preventive training intervention, and (c) injury incidence was reported with the number of ACL injuries. Six studies were included and their methodological quality was assessed using the ROB 2.0 tool. The results show that most interventions included more than one training component with a median duration of 15 minutes and that the exercises which varied most across the programmes were plyometrics.<\/p>\n\n\n <div class=\"tags\"> <p><strong>Keywords:<\/strong> <span>anterior cruciate ligament<\/span>, <span>Prevention<\/span>, <span>training<\/span>, <span>women\u2019s handball<\/span><\/p> <\/div> \n\n\n\n<h2 class=\"wp-block-heading\"><strong>Introduction&nbsp;<\/strong><\/h2>\n\n\n\n<p>Handball is one of the sports with the highest number of non-contact anterior cruciate ligament (ACL) injuries (<a href=\"#8\" class=\"ek-link\">De Lo\u00ebs et al., 2000<\/a>; <a href=\"#28\" class=\"ek-link\">Myklebust et al., 1997<\/a>). In 90% of cases, the injury is associated with cutting or single-leg landing from a jump (<a href=\"#30\" class=\"ek-link\">Olsen et al., 2004<\/a>; <a href=\"#42\" class=\"ek-link\">Takahashi et al., 2019<\/a>). These types of actions typically involve the valgus position of the knee in flexion and internal rotation of the tibia relative to the femur, which is the main mechanism of ACL injury (<a href=\"#19\" class=\"ek-link\">Koga, H., 2010<\/a>). It is one of the most serious injuries, both because of the prolonged period required to return to competition and the long-term consequences (<a href=\"#21\" class=\"ek-link\">Lai et al., 2018<\/a>).<\/p>\n\n\n\n<p>The ACL injury rate in women handball players is 0.7-2.8 injuries per 1,000 hours of exposure (<a href=\"#29\" class=\"ek-link\">Myklebust et al., 1998<\/a>), with an incidence two to five times greater than in their male counterparts (<a href=\"#23\" class=\"ek-link\">Montalvo et al., 2019<\/a>). This difference is also found between the ages of 12 and 16, and women players are at greatest risk of sustaining this injury during adolescence (<a href=\"#20\" class=\"ek-link\">LaBella et al., 2014<\/a>; <a href=\"#35\" class=\"ek-link\">Reckling et al., 2003<\/a>).<\/p>\n\n\n\n<p>Intrinsic and non-modifiable anatomical and hormonal risk factors, coupled with modifiable risk factors associated with neuromuscular control, are the most important aetiological contributions to ACL injury in women athletes (<a href=\"#14\" class=\"ek-link\">Griffin et al., 2006<\/a>; <a href=\"#37\" class=\"ek-link\">Shultz et al., 2015<\/a>). Since the injury is multifactorial in origin, the first prevention strategy should be to identify the modifiable risk factors (<a href=\"#12\" class=\"ek-link\">Fort-Vanmeerhaeghe &amp; Romero, 2013<\/a>).<\/p>\n\n\n\n<p>Women athletes tend to present less knee and hip flexion (<a href=\"#5\" class=\"ek-link\">Bencke et al., 2018<\/a>) and increased knee valgus (<a href=\"#15\" class=\"ek-link\">Hewett et al., 2005<\/a>) in landing and cutting actions. The relative strength deficit in the lower limbs, particularly in the hamstrings (<a href=\"#9\" class=\"ek-link\">DiStefano et al., 2015<\/a>) and a lower activation of the latter relative to the quadriceps in this type of action, increases anterior tibial traction forces and consequently generates greater stress on the ACL (<a href=\"#2\" class=\"ek-link\">Ahmad et al., 2006<\/a>).<\/p>\n\n\n\n<p>Preventive training recommends that consideration be given to the risk factors described (<a href=\"#13\" class=\"ek-link\">G\u00f3mez et al., 2019<\/a>), mainly targeting abnormal biomechanical movement patterns and neuromuscular alterations and adapting to the training principles (<a href=\"#12\" class=\"ek-link\">Fort-Vanmeerhaeghe &amp; Romero, 2013<\/a>; <a href=\"#43\" class=\"ek-link\">Taylor et al., 2015<\/a>). A lower risk of ACL injury has been demonstrated in women athletes following multifactorial and general preventive training (<a href=\"#26\" class=\"ek-link\">Myer et al., 2013<\/a>; <a href=\"#34\" class=\"ek-link\">Petushek et al., 2019<\/a>; <a href=\"#38\" class=\"ek-link\">Soomro et al., 2016<\/a>; <a href=\"#40\" class=\"ek-link\">Sugimoto et al., 2016<\/a>).<\/p>\n\n\n\n<p>The objectives of this review were to identify and categorise the common components of preventive training programmes for anterior cruciate ligament injury in women handball players and to describe and classify the exercises comprising each category.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Method<\/strong><\/h2>\n\n\n\n<p>The study followed the guidelines of the PRISMA Statement for systematic reviews to guarantee an appropriate structure and performance (<a href=\"#44\" class=\"ek-link\">Urrutia &amp; Bonfill, 2010<\/a>).<\/p>\n\n\n\n<p>A literature search was conducted in the Web of Science (WOS), Sport Discus, PubMed, Scopus, Cochrane and ScienceDirect databases combining the following keywords: \u201c<em>female<\/em>\u201d or \u201c<em>woman<\/em>\u201d or \u201c<em>girl<\/em>\u201d, \u201c<em>handball<\/em>\u201d, \u201c<em>exercise<\/em>\u201d or \u201c<em>training<\/em>\u201d or \u201c<em>prevention<\/em>\u201d or \u201c<em>intervention<\/em>\u201d and \u201c<em>ACL injury<\/em>\u201d or \u201c<em>anterior cruciate ligament injury<\/em>\u201d or \u201c<em>lower limb injury<\/em>\u201d or \u201c<em>knee injury<\/em>\u201d (Table 1).

(2015)<\/a>, who conclude that strength training combined with plyometric training is the best combination for lowering the risk of ACL injury in adolescent girls.<\/p>\n\n\n\n<p>Strength training was under-represented in the studies reviewed (3\/6&nbsp;=&nbsp;50\u2009%). <a href=\"#25\" class=\"ek-link\">Myer et al. (2004)<\/a> and <a href=\"#22\" class=\"ek-link\">Lloyd and Oliver (2012)<\/a> emphasised the priority of developing this capacity in growth stages, especially in girls, to offset the anthropometric and hormonal changes that take place during peak height velocity (PHV). <a href=\"#11\" class=\"ek-link\">Fort-Vanmeerhaeghe et al. (2016)<\/a> argue that the aim is to create a stable structure prior to plyometric or more sport-specific work to reduce the neuromuscular risk factors described above since, unlike in boys, no correlations have been demonstrated between height, weight and neuromuscular performance in the maturation phase in girls (<a href=\"#16\" class=\"ek-link\">Hewett et al., 2016<\/a>).<\/p>\n\n\n\n<p>Balance work was used in all the studies in the review (Table 3) and in most cases (5\/6&nbsp;=&nbsp;83\u2009%) it was combined with another component. This is consistent with the results of the reviews by <a href=\"#46\" class=\"ek-link\">Yoo et al. (2010)<\/a> and <a href=\"#41\" class=\"ek-link\">Sugimoto et al. (2015)<\/a> in women athletes, which showed that balance work does not yield results by itself but does do so in combination with other components.<\/p>\n\n\n\n<p>Landing stabilisation exercises geared towards optimising muscle activation to ensure proper jump technique and alignment (soft landing and aligned knees) had been included by definition in the plyometric component. Other studies, such as those by <a href=\"#6\" class=\"ek-link\">Brunner et al. (2019)<\/a> and <a href=\"#34\" class=\"ek-link\">Petushek et al. (2019)<\/a>, classified them as technical exercises. <a href=\"#6\" class=\"ek-link\">Brunner et al. (2019)<\/a> attached less importance to them because the sports they reviewed (football and floorball) did not include jumping as a common action. By contrast, in handball, jumping and jump receptions, particularly on one leg, are one of the specific actions which, together with one-on-one actions, most trigger a set of mechanisms that can result in ACL injury (<a href=\"#28\" class=\"ek-link\">Myklebust et al., 1997<\/a>; <a href=\"#30\" class=\"ek-link\">Olsen et al., 2004<\/a>; <a href=\"#42\" class=\"ek-link\">Takahashi et al., 2019<\/a>). For this reason, the progression of plyometric work should focus on landing technique to gradually step up intensity and variability, for example by involving various planes and axes, including perturbations with external stimuli or a mobile one, combining expected and unexpected actions to improve feedforward capacity, increasing the intensity of the muscle stretching and shortening cycle, combining elastic and reactive actions and progressively introducing a fatigued state (<a href=\"#4\" class=\"ek-link\">Bedoya et al., 2015<\/a>; <a href=\"#10\" class=\"ek-link\">Ford et al., 2011<\/a>; <a href=\"#11\" class=\"ek-link\">Fort-Vanmeerhaeghe et al., 2016<\/a>).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Training programme duration<\/strong><\/h3>\n\n\n\n<p>Most of the studies lasted approximately 15 minutes (Table 3).

(2018)<\/a> provide a detailed description of the exercises included in the ACL injury prevention programmes.<\/p>\n\n\n\n<p>Nordic Hamstring is the exercise proposed by the three studies that include strength in their training programme. It is essential to perform strength work and activation of the hamstring musculature in positions close to maximum knee extension, as this helps to prevent anterior translation of the tibia and protects the ACL (<a href=\"#41\" class=\"ek-link\">Sugimoto et al., 2015<\/a>).<\/p>\n\n\n\n<p>The planks recommended by <a href=\"#1\" class=\"ek-link\">Achenbach et al. (2018)<\/a> in their training programme are designed to enhance neuromuscular control of this area, as strength deficits and poor trunk control in exercises involving rapid changes of position during cutting, planting and landing movements compromise dynamic stability and lead to increased knee abduction load (<a href=\"#47\" class=\"ek-link\">Zazulak et al., 2007<\/a>). The non-contact ACL injury mechanism in women athletes has been shown to involve lateral trunk lean with the body moving on one leg and will therefore be one of the patterns to be corrected when agility tasks are performed (<a href=\"#17\" class=\"ek-link\">Hewett et al., 2009<\/a>; <a href=\"#30\" class=\"ek-link\">Olsen et al., 2004<\/a>).<\/p>\n\n\n\n<p>Altering the state of balance through the perturbations proposed in the training programmes is designed to improve awareness of the position, movement and muscular regulation of the knee joint in response to a stimulus, i.e. to stimulate the proprioceptive receptors to promote muscular coactivation and improve activation time (<a href=\"#32\" class=\"ek-link\">Padua et al., 2018<\/a>).<\/p>\n\n\n\n<p>Even so, <a href=\"#11\" class=\"ek-link\">Fort-Vanmeerhaeghe et al. (2016)<\/a> suggest that balance exercises should target specificity and dynamism in sports movements, since when players sustain the ACL injury they are usually in motion, for example, cutting or landing after a jump.<\/p>\n\n\n\n<p>Learning to land is probably more important than learning to jump, since a player may have to absorb a load of between 5.7 and 8.9 times her body weight depending on flight trajectory and time and jump speed (<a href=\"#24\" class=\"ek-link\">Mothersole et al., 2014<\/a>). <a href=\"#1\" class=\"ek-link\">Achenbach et al. (2018)<\/a>, <a href=\"#27\" class=\"ek-link\">Myklebust et al. (2003)<\/a> and <a href=\"#33\" class=\"ek-link\">Petersen et al. (2005)<\/a> include drills that combine landing skills with other movements. Exercises aimed at reducing ground contact time should be performed once the previous levels have been achieved, while guaranteeing quality of movement.<\/p>\n\n\n\n<p>Most of the plyometric exercise proposals are general, meaning that greater specificity is needed to enable the player to recognise the movement patterns that may be conducive to the ACL injury mechanism (<a href=\"#11\" class=\"ek-link\">Fort-Vanmeerhaeghe et al., 2016<\/a>).<\/p>\n\n\n\n<p>Based on the available evidence, it is recommended that multi-component training programmes aimed at reducing the risk of ACL injury should include feedback on technique and movement quality and also include agility, balance, strength and plyometric exercises.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusions<\/strong><\/h2>\n\n\n\n<p>Training programmes for preventing ACL injury in women handball players are performed two to three times a week for approximately 15 minutes. They are categorised into five components: running, agility, strength, balance and plyometrics. The same programme may consist of one or more components. The most frequent combination was plyometric training with balance training, and balance training was the common component in all the training programmes.<\/p>\n\n\n\n<p>Exercises in the running category are designed to improve running technique; agility exercises include planting and cutting combined with movement actions; strength exercises focus on the lower limbs and trunk; balance exercises are on stable and unstable surfaces, with single- or two-leg support and using a ball; finally, plyometric exercises are performed on various planes and axes with perturbations and landings on one or two legs and also from different heights.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Limitations<\/strong><\/h2>\n\n\n\n<p>One of the main problems was the small number of studies, high variability in terms of components and their combination and the lack of individualisation of the contents of the training programmes based on player characteristics.<\/p>\n\n\n\n<p>Only outcomes in women handball players were analysed in all the articles, except the papers by <a href=\"#1\" class=\"ek-link\">Achenbach et al. (2018)<\/a> and <a href=\"#31\" class=\"ek-link\">Olsen et al. (2005)<\/a> which also included male participants. The women players analysed in the study by <a href=\"#48\" class=\"ek-link\">Zebis et al.
