Female Athlete Health, RED-S and the Research Gap in Women’s Sport with Dr Kate Ackerman

Female athlete health is often discussed in extremes: either physiology is underplayed, or every difference gets turned into a rule.

This conversation sits in the middle, where evidence, clinical context and nuance matter.

In this episode of Stronger With Time, Tony speaks with Dr Kathryn “Kate” Ackerman, a former elite rower, sports medicine physician, endocrinologist and leading researcher in female athlete health.

Kate’s work sits at the intersection of sport, medicine, endocrinology and performance. She explains how her own experience as an athlete shaped her career, why the data gap in female athletes still matters, and how better research can improve both health and performance.

Tony and Kate discuss RED-S, low energy availability, menstrual dysfunction, bone stress injuries, fueling, carbohydrate availability, hormone therapy, menopause, and how to think about female athlete health without turning every difference into a rule.

They also explore the nuance often missing from online discussions: not every calorie deficit is RED-S, not every female athlete needs a bespoke training plan based on physiology alone, and the goal is not to create fear, but to understand what the evidence can and cannot tell us.

In this episode, they cover:

• The evolution from the Female Athlete Triad to RED-S

• What low energy availability means, and when it becomes a problem

• Why RED-S requires clinical nuance, not just symptom counting

• Screening tools, clinical markers and medical context

• Bone stress injuries, DEXA, HR-pQCT and delayed bone recovery

• Transdermal estrogen, oral contraceptives and bone health in amenorrheic athletes

• Adolescent athletes, loading, fueling, calcium, vitamin D and stress injury risk

• Carbohydrate availability, meal timing and recovery

• Menopause, HRT and the gaps still left in women’s health research

• Why female physiology matters, without turning everything into a sex-specific rule

This conversation is for coaches, clinicians, female athletes, parents of young athletes, and active women who want a clearer, evidence-informed understanding of female athlete health.
