<p data-pm-slice="1 1 []">The RPE scale complements other training metrics to create a holistic approach to fitness monitoring. Combining RPE with heart rate data, power output, or time-based performance goals allows athletes and coaches to fine-tune training plans for maximum efficiency. For example, if an endurance athlete experiences elevated RPE levels despite maintaining a consistent heart rate, rpe it may indicate fatigue, dehydration, or overtraining. Recognizing such patterns allows for timely adjustments in workload, nutrition, or recovery strategies.
