The effect of strenuous exercise on blood constituent was examined. Studies were made on healthy 13 members (18 to 27 years) of the canoe club of a medical university who participated in summer training camp for 7 days. Situation of food intake on before and during training camp were also evaluated. Intake of total energy, protein, and carbohydrate during training camp were increased when compared with that of before training camp, but intake of fat as not changed. After training camp, serum total protein, albumin, and total electrolyte (Na⁺, K⁺, ca²⁺) were not affected. Serum GOT, GPT, LDH, and CPK activities were significantly increased. RBC, Hb, Ht and serum haptoglobin were significantly decreased and reticulocyte was increased after the camp. Serum Zn level were significantly decreased but Cu and Fe levels were not changed. Serum antioxidative substance (ascorbic acid and α-tocopherol) levels were significantly decreased, while lipid peroxide level (malondialdehyde) was significantly increased. These data suggest that strenuous exercise can result in a decrease of RBC, Hb, and Ht with oxidative damage.
