## 4 Discussion  
After the analysis of the results, the existence of both physical and mental fatigue in esports players was demonstrated. This demand resulted in a decrease in their muscular capacity, having an impact on their fatigue perception in general terms, as has been previously demonstrated in other studies with other populations [29, 62]. On the other hand, when studying the loss of muscle function applied to joint range and jumping ability, it was possible to observe, in both sessions, a decrease in the players' neuromuscular capacity. These losses align with those observed in previous studies applied to samples with similar \begin{table}

In both cases, these occupations require a large number of hours sitting down to perform physically and mentally demanding tasks in front of a computer, leading to problems associated with muscle decompensation or pathologies located in regions similar to those of esports players. These localized imbalances in regions most demanded by players, such as the shoulder and wrist areas [12], can eventually lead to more significant pathologies, which could hamper the players' careers, even leading to their retirement [11; 14]. Based on this, the present study highlights the importance of healthcare professionals intervening in prevention protocols and the enhancement of pathologies, generally focused on players and, specifically, on the most demanded regions [3]. Additionally, these pathologies and imbalances can result in possible chronic muscular and joint pain, a finding demonstrated when applied to other samples, such as athletes or workers [34; 36].
