Scientific Facts About the New Social Media Trend Cycle-Syncing
While the cycle-syncing trend, which advocates for women to adjust their exercise programs according to their menstrual cycle, is spreading on social media, experts state that there is insufficient scientific evidence.
The cycle-syncing trend, which is spreading rapidly on social media and envisions women shaping their training routines according to the phases of their menstrual cycle, is attracting great interest. However, experts emphasize that these programs, which contain rigid rules, are based on marketing rather than scientific evidence, and that individuals should listen to their bodies.
A Rapidly Spreading Trend on Social Media
Supported by thousands of content on platforms like TikTok and Instagram, the cycle-syncing method advocates for changing exercise intensity during different phases of the menstrual cycle. While Google searches have experienced a huge surge, the number of videos shared under the hashtag has exceeded tens of thousands.
Programs Divided into Four Phases
These applied programs divide the menstrual period into four distinct phases. While light exercises are recommended during the menstruation phase, increasing training intensity is advised during the follicular and ovulation periods, and slowing down again during the luteal phase.
No Scientific Evidence Available
Kelly McNulty, a researcher from Leeds Beckett University, stated that there is not enough research showing that all women should train in specific ways during specific phases. McNulty expressed that this trend is based more on marketing than research.
Personal Differences and Standard Programs
The fact that the menstrual cycle varies from person to person and differs from cycle to cycle even in the same person makes it difficult to implement standard programs. These recommendations remain limited for women who experience irregular periods or use hormonal birth control methods.
Listening to the Body Instead of Rigid Rules
Experts and experienced trainers convey that rather than sticking to a rigid program, shaping one's workouts according to how they feel at that moment is more accurate, and that some women can show high performance even during their menstrual period.
Nocebo Effect and Expert Warnings
Dr. Faye Bate stated that messages indicating performance will drop during certain periods of the menstrual cycle can lead to the nocebo effect. Furthermore, warnings were made that constantly reducing resistance training may limit strength development in the long run.
Awareness and Information Source Approach
Instead of cycle-syncing, scientists recommend a cycle-aware approach. It is advised that the menstrual cycle should not be seen as a set of rigid rules, but rather as a source of information to help understand the body.
