Effects of Whey Protein Supplementation on Hematological Parameters in Healthy Young Resistance Male Athletes
S. Eslami, M. Karandish, S.M. Marandi and A. Zand-Moghaddam

Physical activity changes hematological parameters in athletes which result in cessation of their exercises. There is limited data available about the effects of protein supplements on hematological parameters of resistance exercise. In this clinical trial, changes of hematological parameters were studied after one month resistance training and whey protein supplementation in 32 healthy young subjects (16 in supplement group and 16 in control group). Whey protein supplement (6.6 g day-1) and placebo (starch, in a same dose as the supplement) were consumed between meals. Every one exercised with 80% 1 RM, for 1 h a day, five days a week. Fasting blood specimens were taken before and after beginning of study and WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT and percent of WBCs were investigated separately. Student t-test and paired t-test were used for statistical analyses. WBC, RBC, HGB, HCT, PLT and MCHC levels in two groups significantly decreased (p<0.05), without any difference between two groups. MCV increased in the both study groups, but again there was no difference between them. MCH and lymphocytes% remained unchanged in both groups. In the supplement group, neutrophils % and other WBCs showed no noticeable changes, but in the placebo group, they were significantly increased and declined, respectively. However, no important difference was seen between two groups with respect to percentage of WBCs, separately. In conclusion, one month of whey protein supplementation with 6.6 g day-1 has no effect on hematological parameters changes after resistance exercise. Further studies with various dosages and longer periods of time are recommended.
