Performance Effects of Overtraining Syndrome

Balancing Energy Intake with Energy Expenditure for Female Runners

Overtraining syndrome is more common amongst runners than you would think. Often an enthusiasm for running, improving performance and body composition can lead to runners being over zealous with their training plans. Many focus on training and neglect to pay attention to their requirements for good nutrition and adequate rest.

The inter-play of chronic over exercising with insufficient energy intake (from food) and insufficient sleep/rest may lead to a prolonged and unexpected decrease in performance and deterioration in both physical and mental health.

We discuss the Sports Performance Triangle, Female Athlete Triad (FAT) and Relative Energy Deficiency in Sport (REDs).

Fascinating insights into the importance of balancing energy intake with energy expenditure to promote running performance and overall great health.
