A major meta-analysis led by McNulty (2020) shows that hormonal variations have only a minimal and clinically insignificant impact on the overall physical capabilities of female athletes. An umbrella review conducted by Colenso-Semple (2023) also confirms that it is premature to impose universal training rules based on cycle phases. Indeed, scientific data reveal, above all, an immense variability from one person to another in how the body reacts over the weeks. Rigid training schemes based on the hormonal calendar therefore lack solid evidence. Conversely, the creator’s invitation to self-observe in order to adjust one's practice according to one's own sensations is perfectly validated by research. Listening to one's energy signals remains the most relevant strategy for personalizing physical activity.

What the graded evidence says

Evidence: B

Linked to, not proven to cause.

Effect: cycle regularity as a clinical health indicator — Endorsed by AAP/ACOG as a 'vital sign': deviations in cycle length, regularity or flow can flag underlying endocrine, metabolic or nutritional conditions. Qualitative guideline/consensus, not an effect estimate.
Measured on: adolescents and adults who menstruate

Cycle regularity is a useful general signal, not a specific test: an irregular cycle points to 'worth looking into', not to any one cause. Noli surfaces the idea and encourages tracking; a clinician interprets the specifics.
