Professor: Big And Strong May Not Last as Long

In the battle of the sexes, new UBC research suggests that men may be stronger physically but women have much greater muscle endurance than their male counterparts.

In a new study from UBC's Okanagan campus, researchers in the School of Health and Exercise Sciences have found that women are considerably less exhausted after natural, dynamic muscle exercises than men of similar age and athletic ability.

"We've known for some time that women are less fatigable than men during isometric muscle tests -- static exercises where joints don't move, such as holding a weight -- but we wanted to find out if that's true during more dynamic and practical everyday movements," says Assistant Professor Brian Dalton. "And the answer is pretty definitive: women can outlast men by a wide margin."

In his study, done in collaboration with the University of Guelph and University of Oregon, Dalton recruited eight men and nine women that were at a similar level of physical fitness. Participants were asked to flex their foot against a suite of sensors as quickly as they could 200 times. The speed, power and torque of their movements and electrical activity of their muscles was then captured and recorded over time. more
