Increasing a woman's testosterone level boosts running capacity finds new studyIn the first study of its kind, new European research has found that higher testosterone levels in females have a significant effect on a woman's ability to run for longer. One group applied 10 mg of testosterone cream to the outer thigh each day for ten weeks, the other 10 mg of an inactive (placebo) substance. The women's hormone levels and body composition -- percentage of body fat and lean muscle mass -- were measured at the beginning and end of the ten weeks.
