However we all know that girls are at the next danger of succumbing to heat-related sickness and might attain hyperthermic ranges – with an abnormally excessive physique temperature – in a shorter time period.
Nearly all of analysis on how feminine athletes ought to prepare for the warmth relies on what works for males, and this comes with apparent issues. Not solely are women and men constructed otherwise, however ladies even have a month-to-month cycle of hormones – and this has a robust impact on the physique.
Menstruation could cause muscle aches, joint pains and tender breasts. Then there’s the complications, cramps, bloating, diarrhoea and constipation. So it stands to motive then that intervals could have a detrimental affect on a girl’s sports activities efficiency.
