A physically fit man is typically stronger than women of the same level fitness, but women have the upper hand when it comes to muscle endurance. Consider the findings of a study from the University of British Columbia conducted in collaboration with the University of Guelph and University of Oregon. 

Researchers had 8 men and 9 women matched for their levels of fitness flex their foot against an array of sensors 200 times as fast as they could. The speed, power and torque of their movements were recorded along with fatigue. Male subjects were faster and more powerful, but also fatigued more quickly than female subjects.
