Hormones & Performance

50–71%

of female athletes report that their menstrual cycle affects their athletic performance—either positively or negatively.

Current research suggests hormonal changes throughout the menstrual cycle may influence strength, endurance, recovery, and injury risk. Explore the science behind these changes and learn how to apply them to your training.

Hormone Breakdown

Estrogen & Progesterone

Estrogen and progesterone fluctuate throughout the menstrual cycle, influencing strength, recovery, metabolism, injury risk, and athletic performance.

Estrogen

Highest Levels

Days 6–15, 20–23

Late Follicular • Ovulation • Mid Luteal

Lowest Levels

Days 1–5, 24–28

Early Follicular • Late Luteal

Enhances neuromuscular activation

Faster muscle signaling and heightened reflexes.

Supports muscle growth

Increases protein synthesis and muscle maintenance.

Supports bone health

Maintains bone density and lowers fracture risk.

Improves mood and energy

Increased serotonin production may reduce anxiety and improve well-being.

Increases ligament laxity

May increase the risk of ligament-based injuries during peak estrogen levels.

Progesterone

Highest Levels

Days 16–28

Early Luteal • Mid Luteal • Late Luteal

Lowest Levels

Days 1–15

Early Follicular • Late Follicular • Ovulation

Raises body temperature

Can make exercise in hot environments more challenging.

Supports endurance metabolism

Increases reliance on fat as a fuel source during exercise.

Can reduce muscle-building response

Counteracts some of estrogen's muscle-building effects.

Low levels reduce ligament strength

May decrease the hamstring-to-quadriceps strength ratio, increasing injury risk.

Increases cardiovascular strain

Higher heart rate and greater physiological stress during prolonged exercise.

Hormone Levels Throughout the Menstrual Cycle

Estrogen and progesterone fluctuate throughout the menstrual cycle, influencing strength, recovery, endurance, and injury risk.

Hormone levels throughout the menstrual cycle

Training Throughout the Menstrual Cycle

Hormonal changes can influence training, recovery, and performance. Select a day range to explore how different stages of the menstrual cycle may affect athletes.

Days 6–12

Late Follicular

Hormone Levels

Estrogen rises while progesterone remains low.

Training Focus

Ideal time for heavy lifting, sprint work, power training, and learning new skills.

Nutrition

Maintain adequate carbohydrate and protein intake to support training adaptations.

Recovery

Normal recovery strategies are generally sufficient.

Key Considerations

Many athletes report feeling energetic and strong.

Optimize Your Training

Select a training goal to explore how hormonal changes throughout the menstrual cycle may influence training adaptations and performance.

💪 Strength

Key Hormonal Influence

Higher Estrogen

Best Phase

Late Follicular → Ovulation

Best Days

Days 8–15

Why?

Higher estrogen has been associated with improved muscle protein synthesis, recovery, and strength adaptations in some athletes.

Recommended Training

  • Heavy resistance training
  • Olympic lifting
  • Plyometrics
  • Sprint work
  • High-intensity strength sessions

A Note About the Research

Research on the menstrual cycle and athletic performance is rapidly evolving. While studies suggest that hormonal fluctuations may influence training adaptations, recovery, thermoregulation, and injury risk, responses vary considerably between individuals. These recommendations are intended to provide evidence-informed guidance and should be adapted based on each athlete's unique cycle, symptoms, and training goals.
