Performance Effects of Overtraining Syndrome

May 16, 2020

Balancing energy intake with expenditure.

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 overzealous with their training plans. Many focus on training and neglect to pay attention to their requirements for good nutrition and adequate rest. Balancing energy intake with expenditure is key.

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.

33:01 Key Takeaways from this episode

FEMALE FACTORS

  • RED-S
    • Hormonal disruptiong. The suppression of oestrogen and progesterone
    • Menstrual dysfunction – as a result of suppressed oestrogen and progesterone
    • Increased risk of stress fracture – as a result of reduced oestrogen.
    • Reduced basal metabolic rate – as a result of reduced T3 thyroid hormone production
    • Compromised muscle function – a daily protein intake of less than 30Kcal per Kg of free fat mass is known to reduce muscle synthesis (production).
    • Compromised immune function – leading to increased risk of infection inflammation, and injury.
  • Female Athlete Triad
    • Low energy availability
    • Menstrual dysfunction
    • Low bone mineral density

KEY TAKEAWAYS

  • It is important for a runner to consider training, nutrition, and sleep/rest in equal measure to help prevent the development of Over Training Syndrome
  • Remember that it may occur in men as well as women, so be aware of this with running colleagues and partners
  • Important to take on sufficient food to fuel the amount of exercise you are undertaking
