The aim of this review study is to compare the effects of different intensive physical performances and
competitions from several studies include (football, basketball, 24h marathon race and cycling) games on
hematological parameters of males players. And to find the one with strongest effect on those parameters
among the performances. The Hematological parameter include white blood cell count (WBC ) , red
blood cell count (RBC) count , hemoglobin (HGB), haematocrit (HCT), mean cell volume (MCV) , mean
corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and platelet count
(PLT). Iron and Feritten level also estimated in one study. When comparing the blood values for all the
players before and after the competitions period, there were significant differences in prevalence of most of
blood parameters in all studies but the most impact was in 24 h marathon performance of 11 male runners
who raced for 24 hours around a 400 m oval track, covering at least 100 km of distance. The runners changed
course every 4 hours and were allowed to rest and freely consume food and water. The blood samples were
obtained from subject in 2 and 9 days prior to competition and after competition. The result was showing that
the the runners suffering from distinguish blood anemia appear after competition in 2 day. The findings show
that the hematological parameters could be affected by endurance of performance depending on competition
time period and intensity of physical performance.
