###### Abstract  
The purpose of this study was to evaluate the speed, agility, and explosive strength performance of elite basketball players over an 8-week byometric training program. Fifteen elite male college basketball players in Taiwan (average age 22.16 \(\pm\) 0.85 years old) were publicly recruited. All participants received 24 psychometric training courses three times per week for 8 weeks, and the courses were implemented pre- and post-test. The speed and agility test items were divided into a 20 m sprint and a T-shaped run. In the explosive strength test, a force plate was used to measure countermovement jump to understand the pre- and post-test differences in all the test indicators, including the rate of force development, time of the rate of force development, ground reaction forces for the moment of jumping, duration of passage, and jump height. It was found that, after the participants underwent the pylemotic training program, the body mass index and body fat percentage were significantly reduced, the skeletal muscle mass was significantly increased, and the post-test scores for speed and agility improved significantly. All the participants exhibited a steeper gradient for the rate of force development (r = -0.816\(\sim\)-0.963) and a shorter time for the rate of force development (0.107\(\sim\)0.232 s). The ground reaction forces reached 1509.61-2387.11 Newtons. The duration of passage reached 0.643 s, and the jump height reached 0.624 m. The conclusion was that the pylemotic training program can increase muscle volume in the lower limbs and legs, increase the rate of force development, and shorten the jumping time, thereby enhancing explosive strength. exercise science; biomechanics; force plate assessment systems; pylemotic training programs; sports performance; sports quality +

time spent playing basketball is aerobic exercise, but the time spent performing anaerobic exercise often involves instant dribbling, emergency stop-jump shots, quick layups, and instant takeoffs to compete for rebounds. This shows that repeated sprinting, agility (change in direction and speed), and jumping are essential qualities for basketball players [15]. Muscle strength training can be divided into bare-hand fitness (a no-equipment work-out), barbells, equipment, and pylemetric training (PT); many fitness coaches design variety PT to apply to athletes' training [16; 17; 18; 19]. The term \"pylemetric\" means fast and powerful sports performance [20]. It is a form of explosive training that can improve the force rate and neural response as well as agility and speed [21]. The principle of PT is based on the stretch-shorting cycle, or SSC for short [16]. Plyometric training uses the mutual coordination of muscle concentric contraction and eccentric contraction so that the muscles and connective tissues can fully store elastic potential energy and then use the stretch reflex principle to instantly and rapidly concentrically contract, release stored elastic potential energy, and generate powerful explosive strength [22]. Explosive strength is the momentary muscle strength that directly affects sports performance; the quality of explosive strength is key to sports performance [23]. Compared with the duration of an entire basketball season and the number of games, there is a preparation period of about half a year. During this period, players must practice tactics and perform personal technical training and special physical training; the time to perform muscle strength training is limited. In particular, muscle strength training is related to personal physical fitness and affects the technical performance of players [24; 25; 26; 27]. Therefore, coaches must fully focus on all aspects of training, including endurance, strength, explosive strength, speed, and jumping. Therefore, it is necessary to design new training programs to cultivate the best physical fitness of players in the shortest time.
