The comparison of blood parameters between morning and evening exercise

The purpose of this study was to research to the differences of blood parameters between morning exercise and evening exercises. 12 participants, in younger adults aged 20 years, were recruited and their blood was taken four times, from 8:00 to 9:00 (pre and post) for morning exercise and from 20:00 to 21:00 (pre and post) for evening exercise. The results found that leukocytes (WBC, NE and LY), erythrocytes (RBC, HGB, HCT, MCH and MCHC) and thrombocyte (PLT, MPV and PCT) show resulting differences (p<0.05) between the morning and evening exercises. Additionally, no significant differences were found in the other parameters in blood. In conclusion; Hematologic parameters display different behaviors exhibit acute exercise at different times of day. Leukocytes, erythrocytes and thrombocyte levels display different behaviors as exercises at morning and evening.
