This study aim to evaluate the changes in physiological and performance indicators after a 12-week preparatory phase of four female national-level road cyclists using a power measuring device. The cyclists were monitored load over the preparatory training phase using power meter. Changes in physiological and performance indicators were analyzed. The study found a significant changes in resting heart rate and max heart rate. However, the heart rate at different lactate threshold was insignificant changes. Max lactate (mmol), fatigue index (%), power 5 seconds (W/kg), and power 30 seconds (W/kg) showed statistically significant changes with 0.59,-2.3, 0.32, and 0.42, respectively. The result indicated that the tested cyclists had lower resting heart rates and higher max heart rates compared to global average. However, they had lower power output for longer durations, lower VO2 max, and lower power at different lactate thresholds. The results of this study may contribute to the existing body of knowledge and inform future interventions aimed at optimizing training programs and enhancing performance in various athletic disciplines.
