By designing models that better fit training data and generalize to unseen scenarios, these methods significantly enhance athletes' competitive performance. RL-based training schemes have shown advantagesacrossvariousperformancemetrics,leadingto improved career outcomes for athletes and offering innovativeapproachestotrainingstrategies.However,these methodshavesomedrawbacks.RL andDRLrequirelarge amountsofdataandextensivetrainingtime,whichcanbe resource-intensive.Additionally,thesemodelsmaystruggle to account for unpredictable factors such as injuries or sudden changes in an athlete's physical condition. The complexity of RL and DRL algorithms also makes them difficult to implement and require specialized knowledge.
