Cardio workouts build stronger hearts in women

Filed under: , ,

When male and female mice exercise, female hearts seem to get more benefit than male hearts. Researchers believe this finding may be translatable into human heart health and may explain why women seem to get more -- heart-wise at least -- out of exercise than men.

Female mice had bigger and stronger hearts than male mice and had a 20% reduction in a protein found in people who have heart disease. Male mice did not see the same reduction. Female mice were also able to run farther and faster on a running wheel than their male counterparts.

Though this research only makes a dent in gender-specific cardiac changes, health experts hope that down the road, studies like this one will lead to better treatment strategies for men and women with cardiovascular illnesses.
