###### Abstract  
The effect of different stretches during warm-up on subsequent performance has been studied. However, no reviews are found in which a meta-analytical analysis is used. The aim was to synthesise the effects of different types of stretching included in the warm-up on jumping performance and ROM. The Cochrane, Sport Discus, PubMed, Scopus, and Web of Science databases were systematically searched. The inclusion criteria included studies analysing the effect of different stretching in the warm-up, on a vertical jump or lower-limb ROM. Sixteen studies were eligible for meta-analysis. In vertical jumping, SS led to a non-significant decrease in jump height (\(\text{SMD}=-0.17\) 95%CI [\(-0.39\), \(0.04\)]; \(\text{I}^{2}=16\)%; \(Z=1.57\); \(p=0.30\)), and DS led to a non-significant increase in jump height (\(\text{SMD}=0.12\), 95%CI [\(-0.05\), \(0.29\)]; \(\text{I}^{2}=4\)%; \(Z=1.34\); \(p=0.41\)). Statistically significant differences were observed between stretches (\(p=0.04\)). Regarding ROM, both stretches showed improvements compared to the control intervention (\(\text{SSSSMD}=0.40\), 95%CI [\(0.05\), \(0.74\)]; \(\text{SDSD}\) = \(0.48\), 95%CI [\(0.13\), \(0.83\)]). However, no differences were observed (\(p=0.73\)) between static and dynamic stretching. A greater presence of dynamic stretching is recommended in the warm-up of those sports that require a good jump height and range of motion. Vertical jump; ROM; stretch 2024 14, 3872.

and ending with the performance of sport-specific exercises [5; 6]. There is controversy about the effect of stretching in the warm-up on subsequent performance, as well as which type of stretching is the most effective depending on subsequent activities. Stretching can take many different forms including static stretching (SS), dynamic stretching (DS), and proprioceptive neuromuscular facilitation (PNF) [7]. SS involves lengthening the muscle and holding it in a slightly awkward position for some time between 15 and 60 s; DS uses momentum and active muscular effort to lengthen the muscle, such as swinging, jumping, or other movements in which the limbs are moved up to or slightly past the regular limits of the range of motion (ROM), holding for less than 3 s; and PNF involves a passive stretching combined with isometric muscle contraction either throughout the joint ROM or at the end of the ROM after the muscle is relaxed and rested before it is stretched again [8]. Throughout the 1960s, SS was used in warm-up routines [9]. Subsequent studies have shown the negative influence of SS on subsequent performance [10; 11]. Currently, the inclusion of DS in the warm-up is more popular [12]. However, the effects and type of stretching within the warm-up are unclear. Studies reflect warm-up protocol biases, such as including an aerobic part before stretching, sport-specific dynamic activities after sport, or only acute effects [10]. Extensive research has studied the effect of the warm-up stretching on performance. The performance has been associated with ROM and vertical jumping [13; 14; 15; 16; 17; 18; 19; 20]. It is considered that vertical jump values can be very important for assessing performance in some sports [21]. Maximum jump height is an indicator of leg muscle power [22] and is related to peak strength, sprinting ability, and change of direction [23; 24]. Moreover, ROM measurements quantify the joint mobility and the status of joint hyper- or hypomobility [25]. Correlations have been established between the changes produced by stretching in the ROM and improvement in performance, [10; 26] and these changes and reductions in the incidence of injuries [27]. Several systematic reviews have been published about the effects of stretching in the warm-up on performance and ROM [9; 10].
