Discussions highlight the consistency of recent scientific evidence, with phrases like 'no influence,' 'limited data,' and 'waste of time' underscoring a consensus on the lack of menstrual cycle effects in resistance training; tone ranges from supportive to skeptical, reflecting a mixture of validation and critique of past beliefs.
AgreementStrong agreement
Most discussions support the conclusion that menstrual cycle phases do not significantly impact strength or training adaptations, indicating strong consensus.
InterestModerate interest
Participants show some curiosity, particularly regarding the implications for training routines, but overall the focus is on confirming existing evidence.
EngagementModerate engagement
Conversations include referencing research summaries and debates about methodology, suggesting moderate engagement with the scientific content.
ImpactModerate impact
While relevant for training practices, the discussions mainly reinforce existing views rather than transforming practices or policy.
Abstract in brief
Current research indicates that a woman's menstrual cycle phase does not significantly impact immediate strength performance or long-term adaptations to resistance training.
Many exercise science studies tend to exclude women due to misconceptions that hormonal fluctuations affect their training outcomes, but evidence suggests these cyclical changes may not have the expected influence.
The review highlights inconsistencies and methodological issues in existing research and emphasizes the need for more accurate menstrual cycle verification; therefore, it is too early to definitively state that hormonal changes during the menstrual cycle affect resistance training results.
Current evidence shows no influence of women's menstrual cycle phase on acute strength performance or adaptations to resistance exercise training https://t.co/8ticLOOsS4

It’s a conception that women need to change their training based on where they're at in their menstrual cycle.
Yes, female hormones fluctuate throughout the menstrual cycle and can most definitely influence mood, strength, energy, and metabolism.

En resumo, este estudo suxire que é prematuro concluir que as flutuacións a curto prazo nas hormonas reprodutivas inflúen significativamente no rendemento do exercicio agudo.
Pese a los muchos intentos por constatarlo, no existe ninguna evidencia de alta calidad que sostenga la periodización del entrenamiento de fuerza en función del ciclo menstrual.

Extremely impactful paper: essentially highlighting that in 2023 we are still no closer to understanding the impact of hormonal menstrual cycles on exercise and performance for women due to low methodological rigour in the literature.
Customizing training plans around factors such as nutrition, fatigue, sleep, stress is key. There's limited evidence that menstrual phases impact performance or adaptations to resistance training. It's early days for hormone-based exercise prescriptions. https://t.co/ZzKpzlqLPe
