# Sports Performance Analysis of Wheelchair Basketball Players Considering Functional Classification
## 4 Discussion
This enables them to perform better during tasks and competitions. When analyzing the kinematic EL variables, it is evident that FC4.0 players covered the greatest distance during the tasks, averaging approximately 54 m per minute. In terms of explosive velocity, FC2.0 players covered the greatest distance, with no differences between the averages of the other FC players. The fact of presenting a high explosive distance signifies and corroborates the intermittent nature of the sport [41,42]. Therefore, explosive strength work sessions and programmes should be developed to improve and perfect the players' performance [43]. In sequence, reviewing the values of the number of acc and dec, as well as the average speed obtained, it was again the players with the highest score (4.0) who presented the highest records due to their great capacity for movement [37] and predisposition during the game to perform the main technical-tactical actions [44]. In this regard, this is the reason why the players with lower FC present values under the average--because of their limitation of movement. The coaching staff needs to design drills that enhance speed, mobility, agility, strength, and both technical and tactical abilities of players to improve their performance during matches. The objective internal load variables are analyzed by studying the heart rate of the players. The results indicate significantly higher values for FC4.0 players compared to the rest of the categories, with maximum values of 172 bpm and working at 73% of the maximum. On the other hand, the players with a lower FC show significant differences regarding FC4.0, with a maximum of beats per minute of around 150. The players present an average pulse rate close to 140, coinciding with previous studies in the literature [45]. These values demonstrate the need for a good aerobic and anaerobic base of the players for the development of a good performance [40]. In addition, due to the different positions and FC, each player presents different physical demands, influencing cardiovascular performance [25,46]. Finally, regarding the neuromuscular variables, such as PL and the number of impacts, it is again the FC4.0 players who present the highest values. These results are due to the large number of impacts that occur during the game both during offensive and defensive actions [47]. The PL is one of the variables that is most closely related to the fatigue or load to which the player is subjected during a task, correlated with external [48] and internal load [49]. Therefore, to reduce injuries and asymmetries as well as to reduce player fatigue, the coaching staff should monitor PL values to determine when players are enduring high training loads since most of the fatigue and load are produced at low-medium intensity [50]. Basketball players need to understand the EL demands during competition and implement a proper warm-up tailored to these needs to prevent injuries [51]. Additionally, the coaching staff should consider the exercises that require players to exert a high physical load, considering the specific playing position. These exercises should be administered with adequate rest time to allow for specific adaptations that directly influence the technical and tactical development of the players. Taking as a reference the correlational analysis of EL and IL variables according to the weight, height, and experience of the players, conclusive and practical results need to be taken into account for the development of personalized training tasks. Considering the kinematic EL variables, a positive correlation is observed between the maximum acceleration variable with height, weight, and experience, i.e., as the independent variables increase, there is a significant increase in the maximum acceleration results. The same occurs with maximum deceleration: a negative correlation is observed in the results. As the values of height, weight, or experience increase, the maximum deceleration values decrease considerably.
