We purposed to investigate the changes in internal training load and shot performance during a 9-hole round of golf in KPGA professional golfers, with the goal of elucidating the influence of physiological and psychological responses on performance. Eight KPGA-certified professional golfers participated in a simulated 9-hole round. Heart rate variability (HRV), blood lactate concentration, and shot metrics were measured at the teeing grounds of holes 1, 5, and 9. Driver shot speed, carry distance, and shot accuracy were assessed and analyzed using repeated measures one-way ANOVA. HRV indicators showed a decreasing trend as the round progressed, while blood lactate concentration peaked at hole 5 and slightly declined by hole 9. Shot analysis revealed the highest ball speed and the lowest shot error at hole 5, indicating improved performance at mid-round. Moderate levels of physiological tension and fatigue may positively contribute to golf performance. HRV and blood lactate levels are suggested to be valuable physiological markers for monitoring player condition and informing strategic decision-making during competitive play.
