How the Menstrual Cycle Affects Women in Sport — And What You Can Do to Stay Injury-Free

Women continue to break barriers in every sport — from grassroots fitness classes to elite competition. Yet for too long, training programs, injury research, and recovery protocols have been grounded primarily in male physiology. That’s changing fast, and exciting new research shows that understanding the menstrual cycle isn’t just a “nice-to-know” — it’s a performance and injury prevention tool.

Why the Menstrual Cycle Matters in Exercise & Sport

The menstrual cycle isn’t one static “period of bleeding” — it’s a rhythm of hormonal changes that influence strength, fatigue, coordination, tissue mechanics, and recovery. The key hormones — estrogen and progesterone — rise and fall in predictable phases:

  • Follicular phase (from menstruation into ovulation): estrogen rises

  • Ovulation: estrogen peaks

  • Luteal phase (after ovulation): both estrogen and progesterone are elevated then decline

These shifts matter for athletes because they influence how muscles, ligaments, and the nervous system behave during movement and under load. (MDPI)

🔎 What Research Is Telling Us Right Now

1. Injury Risk Isn’t Equal Across the Cycle
New prospective studies tracking elite female athletes over seasons show that:

  • Muscle injuries are more frequent in the pre-menstrual and luteal phases — roughly 5–6 times more likely than during menstruation itself. (St Mary's University, Twickenham, London)

  • Elite female footballers (soccer players) display higher overall injury incidence during the luteal phase, when progesterone fluctuates and neuromuscular control can be less stable. (University of Bath Research Portal)

  • Another study found that injuries sustained during menstruation tend to have a higher severity, leading to more time lost from training and sport when compared with injuries at other phases. (Frontiers)

These findings suggest not just when injuries happen, but how seriously they affect training continuity and recovery.

2. Hormones Affect Movement Mechanics
Fluctuating hormone levels — especially estrogen — have been linked to changes in:

  • Joint laxity

  • Muscle strength

  • Neuromuscular control

  • Tissue temperature and elasticity

These factors can influence how women absorb load, respond to sudden direction changes, or control deceleration — all essential in high-impact sport and dynamic exercise. (MDPI)

3. It’s Not Just Physical — Cognitive Performance Also Varies
Emerging research shows female athletes may have faster reaction times around ovulation, which could reduce injury risk in fast-paced sporting contexts. (The Guardian)

Common Injuries Connected to the Menstrual Cycle

While more research is needed (especially into injuries like ACL tears), current evidence points toward:

  • Muscle strains

  • Tendon overload injuries

  • Neuromuscular injury patterns

These are especially likely when hormonal shifts affect muscle coordination and fatigue resistance. (MDPI)

A note: Some experts caution that clear links between menstrual phase and ACL injuries haven’t been firmly established yet — ongoing research is underway to explore this possibility further. (The Times)

✅ How to Help Prevent Injuries Across the Cycle

Here’s how sports massage therapists, trainers, and women athletes can work smarter with the cycle — not against it:

1. Track Your Cycle

Whether through apps or wellness logs, tracking your cycle helps spot patterns in performance dips, fatigue, pain, and recovery. This data can guide when to push intensity and when to emphasise recovery.

2. Adapt Training Intelligently

  • Pre-menstrual & luteal phases may benefit from more focus on neuromuscular control, mobility work, and careful load management.

  • Mid-follicular to ovulation may allow for higher-intensity strength and power sessions, with better muscle responsiveness.

Personal responses vary — so adapt based on how you feel as well as your cycle stage.

3. Use Sports Massage & Manual Therapy Strategically

Regular massage can:

  • reduce muscle tension

  • improve soft tissue pliability

  • enhance proprioception (body awareness)

  • support recovery when fatigue is high

Tailoring massage around phases where fatigue and discomfort peak can support training continuity.

4. Focus on Sleep, Nutrition & Iron Status

Healthy iron levels, anti-inflammatory nutrition, and good sleep not only mitigate fatigue but also support tissue repair — particularly important during menstruation when iron loss is greater.

5. Educate Athletes & Coaches

Breaking stigma and normalising menstrual cycle conversations in gyms and locker rooms empowers women to train in ways that respect their physiology.

Final Takeaway

Understanding the menstrual cycle isn’t about making excuses — it’s about maximising performance and minimising injury risk in an evidence-based, empowering way. Modern research is finally closing the data gap in women’s sports science, and sport-specific menstrual awareness is becoming a competitive edge in performance and injury prevention.
