Short-Term Effect of Circuit Resistance Exercise on Plasma Fibrinogen and Viscosity, and some Platelet Parameters of Young Female Students

The aim of this study was to see the effect of 7 sessions of circuit resistance exercise in consecutive days on plasma fibrinogen and viscosity, and some platelet parameters of young female students.

Twenty volunteer female students in luteal phase of the menstrual cycle were selected and randomly divided into two groups of experimental and control. Experimental group were performed a circuit resistance exercise including 10 nonstop exercise with 60% one repeat maximum in 4 round (20s for each exercise, and 3 min for between round rest). Each session was took 32-40 min with warm up and cool down. Blood sampling was taken 24h before and after first and seventh session of training respectively in 12h overnight fast condition to assay plasma fibrinogen, platelet counts (PLT), mean platelet volume (MPV), platelet distribution width (PDW), and platelet large cell rate (PLC-R). Plasma viscosity was calculated.

Plasma fibrinogen, plasma viscosity, PLT, MPV, and PLC-R elevated significantly affected by 7 consecutive sessions of circuit resistance training; but PDW didn’t change significantly.

Circuit resistance training increased haematological and rheological plasma parameters of coagulation that could possibly affect the long-term cardiovascular health. So, female students must use the between sessions rest for appropriate recovery from circuit resistance exercise. It could be useful for short term adaptation.
