## 2 1 Introduction  
Warm-up is considered an essential element in the athlete's daily routine, as it prepares them for the demands of training or competition [1]. The objective pursued is to increase performance [2] and reduce the injury rate [3]. Diverse physical and physiological responses occur as a result of the performance of a warm-up, including increased muscle metabolism, improved biomechanics of muscle fibers, enhanced neuromuscular activation, elevated oxygen intake, and psychological preparation [2]. To achieve these adaptations, various training methodologies have been proposed, primarily categorized as passive or active warm-ups [4], with the latter further divided into general or sport-specific warm-ups based on the sport in question [5].  
Specific warm-ups are characterized by recreating movements or situations as similar as possible to the usual practice. They aim to achieve a more effective neuromuscular preparation of the elements most involved in the practice [6]. Furthermore, recent evidence suggests that specific warm-ups may provide superior physical and performance effects due to their ability to simulate and/or replicate the stimuli that occur in the respective sport [7; 8]. For basketball, specific physical and physiological demands are required, which are different from other sports disciplines, as it involves a high number of unilateral actions, changes in direction, rhythm, and explosive gestures [9]. Therefore, an optimal training activation in basketball should prepare athletes to properly perform these actions in order to achieve an adequate level of sports performance during practice, minimizing the risk of injury [1; 10].  
Based on these assumptions, specific warm-up protocols have been designed for sports disciplines such as football [11] or volleyball [12]. However, the current scientific literature lacks a specific pre-workout designed for basketball practice that covers its specific demands. In its absence, some of the other specific sports protocols (such as FIFA 11+) are sometimes used for basketball athletes, with conflicting evidence regarding its effectiveness. Some authors observed enhanced outcomes related to sports performance and reduced risk of injury when using FIFA 11+ as a warm-up program for basketball practice [13; 14]. However, other studies did not find such benefits [15; 16]. Furthermore, the effectiveness of FIFA 11+ has not been evaluated in comparison to a basketball-specific program. Therefore, it remains unknown whether a warm-up program tailored specifically for basketball may prepare athletes more efficiently. To attempt to elucidate this aspect, the first step may involve designing a specific basketball warm-up proposal and analyzing the effects produced immediately to avoid additional factors influencing the outcome. Subsequently, the analysis will extend to observe the effects over a longer period of time.  
Consequently, this research aims to evaluate whether Basket-Up, a warm-up designed specifically for basketball, provides immediate benefits in terms of the essential physical performance requirements of basketball. The second aim is to analyze these effects in comparison to those obtained by performing the non-basketball-specific FIFA 11+ protocol. The hypothesis of this trial is the proposed Basket-Up warm-up protocol would enhance immediate performance outcomes similarly to or even more effectively than the FIFA11+ protocol.
