Individuality Affects the Efficiency of Basketball Pre-Game Warm-Up on Players' Performance.

Pre-game warm-up is integral to athletes' preparation before a basketball game. The main objectives of this study were to compare specific performance indicators before and immediately after a basketball pre-game warm-up, and examine the individualized players' responses. The impact of rest intervals after warm-up (9-23 min) was also examined. A total of 20 male basketball players (age: 21.15 ± 2.2 years; body mass: 82.23 ± 10.78 kg; body height: 184.18 ± 7.9 cm) performed a pre-game warm-up and were assessed in selected indicators such as heart rate (HR), flexibility, running speed, and countermovement jump with arm swing (CMJAS) before, immediately after, 9 min and 23 min after warm-up. Immediately after warm-up, HR increased to all players (mean change: 69.78%), while flexibility (mean change: 20.14%) and CMJAS (mean change: 4.95%) increased to the majority of players (except one and two players, respectively). The individualized results regarding speed were conflicting, showing a decrease or increase. However, 9 and 23 min after warm-up, there was a decrease in HR, speed, and CMJAS (p < 0.5), while flexibility remained stable (p > 0.5) in the total sample, with great change variations among players. In conclusion, it seems that each player's individuality may affect the warm-up's efficiency. Thus, it is important to carefully design the pre-game warm-up so that all players will be in the most suitable condition to meet the demands of their competition.
