RT Journal Article T1 The Influence of Functional Movement and Strength upon Linear and Change of Direction Speed in Male and Female Basketball Players A1 Barrera Domínguez, Francisco José A1 Almagro Torres, Bartolomé Jesús A1 Molina López, Jorge AB The present study aimed to analyse the relationship between functional movement and strength variables uponlinear speed (Ls) and change of direction (COD) based on gender. It also aimed to identify the determinants of performanceof Ls and COD according to gender. Fifty basketball players (54% female) completed the assessment in which the weightbearingdorsiflexion test, the Y-balance test, the unilateral countermovement jump, the unilateral drop jump, theunilateral triple hop test, Ls and CODs were performed. Speed variables were divided according to time execution into"low-performance" and "high-performance" to establish a comparison between performance groups. Strength variablessignificantly influenced speed tests’ performance in both genders (p < 0.05). For males, the greater the Ls, the higher thechange of direction deficit (p < 0.001). Multiple regression analysis revealed that a long and vertical stretch-shorteningcycle (SSC) was the most influential physical ability for speed performance in females (45–65% variance explained; p <0.001), while in males, a short and horizontal SSC played a significant role (30–61% variance explained; p < 0.022).These results suggest that gender should be considered in programming strength training to improve speed, as eachgender will benefit most from the application of different force-orientations and different SSC. Also, the faster the maleplayers were in Ls, the less efficient they were in the COD performance. This is why for men, it would be recommendedto perform eccentric exercises along with deceleration and technique drills to improve COD speed.
