Our research has indicated that females can be susceptible to losing more than 1.5 times more amino acids per litre of sweat than males.
A sedentary day under warm conditions would typically lead to a sweat volume of around 500mL to 1 L. Increasing exercise, exertion, especially in warmer climates, can lead to sweating rates of 1-2L per hour.
This would mean that the women have a much higher capacity to lose significant quantities of amino acids through sweat compared with men when they increase exercise intensity or spend more time in warmer conditions.
Women would thus be more susceptible to experiencing fatigue with slower recovery rates from exercise.
Replenishment of high-demand amino acids lost at the faster rates could potentially provide beneficial outcomes in terms of well being and vitality.
