0.5). It appears that both Load 1 and Load 2 accelerated the body metablism in the subjects, as evidenced by theadaptative rise in the frequency, amplitude and index of alpha waves. At a moderate load, the index of beta waves in the occipital region was 8.4% before the experiment, risingto 14.1% (P0.5)the 2-min interval. The increase in beta index in the occipital region indicates an increase of excitability of thecentral nervous system, and its return to normal after the 2-min interval signifies the adaptability of thesubjects.

This essay is to study on the effect of bee-pollen and its suitable dosage on improving sport performances. Fifty athletes were our experimental subjects. The athletes were divided into experiment group and control group. 14 objective indexes were measured before and after taking pollen at each of the 4 times within 3 months on both of experiment group and control group of athletes. The results showed that bee-pollen (15 g per day) improved the cardiac function, muscular strength and enduranco significantly.279 mice were experimental too, they were divided into experiment groups and control group. These animals were put in water for one hour per day in a period of 3 months. They were tested for pole climbing and exhausted swimming after taking pollen by the first, second and third months. Results showed that bee-pollen increased muscular strength and swimming time after taking the pollen at a large dosage.After taking the bee-pollen the body-weight remained somewhat unchanged.There is no observed side effect after taking bee-pollen by athletes.
