There was no group difference in reaction times and accuracy between males and females (using contraception and not). However, within subject analyses revealed that regularly menstruating females performed better during menstruation compared to being in any other phase, with faster reaction times (10ms c.ca, p < .01), fewer errors (p < .05) and lower dispersion intra-individual variability (p < .05). In contrast they exhibited slower reaction times (10ms c.ca, p < .01) and poorer timing anticipation (p < .01) in the luteal phase, and more errors in the predicted ovulatory phase (p < .01). Self-reported mood, cognitive and physical symptoms were all worst during menstruation (p < .01), and a significant proportion of females felt that their symptoms were negatively affecting their cognitive performance during menstruation on testing day, which was incongruent with their actual performance.
That’s interesting but what was the point of the study?
The implications for female sports seem quite apparent.
As well as vampire slaying. Cramps plus heightened senses may save Donald Sutherland next time.
Ok, fair point, I certainly wasn’t thinking of that angle.
Interesting. Other factors should be considered as well, such as the fact that many women feel “icky” and bothered when on their period. So that might be still a net negative.
