Objective: To examine the effects of menstrual cycle on exercise-induced inflammation, we investigated exercise-induced changes in circulating cytokines and leukocyte responses during different phases of the menstrual cycle. Methods: Ten healthy sedentary females (20.5 ± 0.7 years) performed 60 min of cycling at 75% of their individual anaerobic threshold (AT) during the three different phases ...

The present study revealed that most erythrocytes in the menstrual phase are isomorphic but that all erythrocytes detected in the other phases are dysmorphic, suggesti...
