Ananas comosus (L.) Merr. (Bromilaceae), is a fruit wordly consumed. The present study is to evaluate the effects of raw juice of Ananas comosus and aerobic exercise on blood biochemical parameters in obese women. Thirty obese women took part in the experiment for 45 days and were divided randomly in 3 groups of 10 women. Group1 (G1) consumed daily 1,26 L of crude pineapple juice. Group 2 (G2) practiced an aerobic exercises. Group 3 (G3) consumed the pineapple juice and practiced aerobic exercise according to the protocol of G1 and G2. Biochemical, hemodynamic and anthropometric parameters were measured at the beginning and end of the study. The results showed that total cholesterol (TC) and Low Density Lipoprotein cholesterol (LDL-c) decreased significantly in all the 3 proups. Triglycerides have only decreased in G2. The AI and Blood Sugar were significantly low in all three groups. SBP, Rest Cardiac Frequency (RCF) and the weight have decreased only in G3. In conclusion, Ananas comosus raw juice and aerobic exercise have had individually positive effects on the variables studied. In addition, changes in these variables are pronounced in G3 through the associated action of the two treatments.
