## 1 Introduction  
Sports injuries, such as ankle injuries, are a common and recurring problem for many athletes, representing the first worldwide disability in terms of sports, typically manifesting 31% of the injuries in football players and 45% in basketball players [1]. These injuries can be debilitating and require a significant recovery time, taking the athletes out of the game for 3 or more weeks [2]. One of the most common ankle injuries are the strains that cause chronic symptoms in 40% of individuals, such as pain, swelling, and instability, that provoke bad motor control of the ankle joint and can lead to functional disability [3]. Age is a factor that can impact an athlete given that the athlete's risk of injury increases with age. This is because the body's tissues begin the aging process after the age of 35, leading to a loss of elasticity and slower tissue repair [4]. Gender has a minimal impact on the risk of injury as the human body has an equal likelihood of getting injured regardless of gender [5]. The number of hours and days of training has a low impact on the incidence of injuries since the time dedicated to training contributes to muscle strengthening and memory [6]. Previous injuries are a variable that may yield a low result, as athletes with injuries undergo active recovery treatment, play with reduced intensity, and manage play time to prevent fatigue [7]. Corrective treatment is a variant with a small possibility of influencing injuries, as athletes either have undergone or undergo specific treatment for their injuries. Athletes who are injured tend to play with less intensity and in positions with lower physical demands. However, athletes with preventive treatment may have muscles and tissues that have been prepared for physical demands, potentially reducing the incidence of injuries [8; 9]. Hydration is also an important factor in the possibility of getting injured, because it is involved in the metabolism, nutrient transport, blood circulation, and body temperature regulation [10]. In terms of sports, hypohydration plays an important part in the weight loss of athletes, because plasma, blood flow, blood volume, cardiovascular functions, and thermoregulatory capacity are mechanisms that are affected [10; 11]. During training and games, athletes lose different body liquids, mainly by sweating, and these liquids depend on the exercise intensity and the weight of the individual. Kinesiophobia, known as the fear of performing a movement or an activity, plays a role in functional ankle instability. This fear induces negative thoughts, leading to mechanical alterations that impede proper joint functioning. Consequently, the repercussions of the ankle's behavior are a loss of strength, more postural balance, and an alteration to the proprioception of musculoskeletal disorders [3; 12; 13; 14; 15; 16]. Fatigue in athletes can have a significant impact on their performance and increase the risk of injuries [17]. Fatigue can be the result of a variety of factors, including physical exertion, lack of sleep, poor nutrition, and mental stress [7; 18]. Athletes who experience fatigue may have an increased risk of injuries due to several factors: alterations in coordination, reduction in performance capacity [19; 20], and increased vulnerability to infection, also known as chronic fatigue [21; 22]. Hydration is a factor that can have a high impact because muscles not adequately hydrated are prone to fatigue and injuries [23]. Artificial intelligence (AI) and machine learning (ML) are advancing in numerous fields, including medicine [24; 25; 26; 27]. One of the most promising applications of AI in this field is the prediction and prevention of sports injuries. ML is a subset of AI and is divided into supervised and unsupervised learning. In supervised learning a model is trained on a labeled dataset, and the input data are associated with a correct output [28; 29; 30]. The model learns from these data and then is ready to predict the output of new data.
