The Impact of Premenstrual Syndrome (PMS) on Training: Pace Adjustment and Psychological Coping

PMS Is Not “All in Your Head”

Premenstrual Syndrome (PMS) affects approximately 75% of women, with 3–8% experiencing PMDD (Premenstrual Dysphoric Disorder) at a severe level. For athletes, PMS is not just “feeling down”—it is a physiological decline in performance.

Typical PMS Symptoms and Their Impact on Training

Pace Adjustments: Don’t Force a PB

Research shows that during PMS:

• Perceived exertion (RPE) at the same intensity increases by 1–2 levels
• 5K time trial performance drops by an average of 2–4%
• Tolerance for high-intensity intervals decreases significantly

Practical advice: If a Threshold run is scheduled during PMS (5–7 days before menstruation), run 8–12 sec/km slower than usual; if VO2max intervals are scheduled, reduce the number of sets by 1/3. This isn’t backing down—it’s smart training.

Mental Coping Strategies

1. Normalization

Knowing “this is PMS, not a lack of strength” can relieve most of the anxiety. Mark your expected PMS window on the calendar and prepare mentally in advance.

2. Cognitive-Behavioral Adjustments

Avoid doing training reviews or setting new goals during the PMS phase—emotions can distort your judgment. Save these for the follicular phase.

3. What If Race Day Falls During PMS?

• Arrive 10–15 minutes early to warm up, giving your body more time to adapt
• Don’t try new fueling strategies
• Preset heart rate zones 5% lower
• Accept that it may not be a PB day, but you can still finish

Nutritional Interventions

• Calcium 1200 mg/day + Magnesium 300 mg/day: Studies show this can reduce PMS symptoms by up to 48%
• Vitamin B6 50–100 mg/day: Improves mood-related symptoms
• Omega-3 EPA 1–2 g/day: Anti-inflammatory, reduces breast tenderness
• Avoid: High-sodium foods (worsens edema), alcohol, excessive caffeine

When to Seek Medical Intervention

If PMS severely impacts daily life and training:

• SSRI antidepressants: Effective when used during the luteal phase
• Combined oral contraceptives: Stabilize hormones, but the impact on performance must be assessed
• It is recommended to consult an OB-GYN or sports medicine physician familiar with female athletes

One Key Concept

The biggest variable in the relationship between PMS and athletic performance is not the severity of symptoms, but “whether it is anticipated and accepted.” Build it into your training plan—don’t treat it as an unexpected event.
