<![CDATA[Speed, Agility, and Quickness (SAQ) training is widely recognized as an effective approach to improve athletic performance in basketball, a sport requiring rapid movement, directional changes, and cardiovascular efficiency. Previous research has demonstrated that SAQ training significantly enhances speed, agility, and skill performance with statistically significant outcomes (p < 0.05) across multiple variables (Sun et al., 2025; Moselhy, 2020). Therefore, this study aimed to examine the effect of SAQ training on selected physical abilities, basketball skills, and functional heart variables, as well as to develop a tailored training program. An experimental one-group pretest–posttest design was used, involving 15 basketball players aged 17–18 years from Hit Sport Club. A preliminary study with 5 players was conducted to validate the procedures. Data were analyzed using paired sample t-tests. The results showed significant improvements (p < 0.05) in all variables. Physical performance increased, with transitional speed improving by 21.60% and agility by 24.06%. Skill performance also improved, including shooting accuracy (26.85%) and lay-up performance (41.86%). Functional heart variables demonstrated positive adaptations, including exercise heart rate (24.50%), resting heart rate (4.05%), and post-exercise heart rate (46.44%), consistent with previous findings (Lee et al., 2024; Si et al., 2025). In conclusion, SAQ training effectively enhances physical fitness, basketball skills, and cardiovascular efficiency, supporting its inclusion in modern basketball training programs.]]>
