In a new study from UBC香蕉视频直播檚 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.
香蕉视频直播淲e香蕉视频直播檝e known for some time that women are less fatigable than men during isometric muscle tests 香蕉视频直播 static exercises where joints don香蕉视频直播檛 move, such as holding a weight 香蕉视频直播 but we wanted to find out if that香蕉视频直播檚 true during more dynamic and practical everyday movements,香蕉视频直播 said assistant professor Brian Dalton, in a press released out of the university.
香蕉视频直播淎nd the answer is pretty definitive: women can outlast men by a wide margin.香蕉视频直播
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.
香蕉视频直播淲e chose to measure foot movements because it makes use of calf muscles on the back of the leg, which are essential for practical, everyday tasks like standing and walking,香蕉视频直播 said Dalton. 香蕉视频直播淲hat we found is that males were faster and more powerful at first but became more fatigued much faster than females.香蕉视频直播
While only one isolated muscle group was studied, Dalton says he would expect similar results for other muscles groups and his results are consistent with what has been observed elsewhere.
香蕉视频直播淲e know from previous research that for events like ultra-trail running, males may complete them faster but females are considerably less tired by the end,香蕉视频直播 he adds. 香蕉视频直播淚f ever an ultra-ultra-marathon is developed, women may well dominate in that arena.香蕉视频直播
But it香蕉视频直播檚 not all about competition. Dalton says his results can also inform more practical applications, such as designing exercise programs or even adapting work environments to minimize work-related fatigue and improve overall productivity.
香蕉视频直播淲e may, for example, want to lower the load for males, even though they may be stronger at the outset, to more closely match the endurance observed in females,香蕉视频直播 he said. 香蕉视频直播淏oth sexes have valuable physical abilities and it only makes sense that we study and develop the tools to afford them the best advantage.香蕉视频直播
The study appears in the June 2017 issue of Applied Physiology, Nutrition, and Metabolism and was conducted with financial support from Natural Sciences and Engineering Research Council of Canada.
