Run Lean Run Fast

Body composition is important for a runner. High body fat and low lean muscle could result in slow, sluggish running, however low body fat may result in injury, illness and muscle breakdown.

In this episode we’re talking dietary and training approaches to attaining optimal body composition, and also identifying factors influencing the ability to achieve an “ideal body composition”.

FEMALE FACTORS

  • Menopause is known to slow RMR as a result of reduced oestrogen levels so could affect energy balance and lead to weight gain.
  • Menopause also leads to some weight gain because fat cells are known to be one of the principle Sources of oestrogen production following cessation via the reproductive system.
  • The adrenal glands are the other principle source of oestrogen production in menopause. Adrenals glands produce stress hormones in response to stressors – endurance running is a stressor. If there is a high demand for stress hormones then this may take priority over female sex hormone production.
  • Females tend to be more conscious of their weight than men.
  • Females are greater risk of REDs and the symptoms/conditions accompanying it.
  • Managing your expectations regarding body composition is key for women (but also men) in middle/old age.

  • Be mindful of what you are striving for in body composition – is it realistic and healthy?
  • A combination of a nutrition plan and exercise (mix of resistance and cardiovascular) is important to achieve appropriate body composition
  • A general approach to macro nutrient composition would be healthy fat intake, optimal protein and strategic use of carbohydrates in line with training
