A Research On The Status And Characters Of Biology Of The 9-12 Years Old Badminton Reserve Talents

The biological status and characters of the badminton reserve talents are closely related to the fostering of the badminton reserve talents and the continuable development of the badminton sport in China. This research took the children players from the Anhua National Training Basis of Badminton as the research subjects, employed the principles and approaches of the human science of exercise such as exercise physiology , sports biomechanics and exercise psychology, choose the new indexes of lean body mass, breath difference, 5-time Vital Capacity, the surround and grip of arm with holding ball, attention-distribution, kinaesthesia-sensitivity of elbow joint and depth feeling, which are closely related to the selection and evaluatation of badminton reserve talents on the base of the previous researching, is targeted to remedy the deficient of psycholo gical indexs, unfull and distinguishing of a short of the indexs.The research shows that: (1) compared with the students of the same age, badminton reserve talents have not sharp difference in height, weight and weight index, while they have a distinct gap in Circumferenc--e, vital capacity, 50-meter dash, standing long jump, situp, and they have a rather low blood pressure, which show that the badminton reserve talents have professional characters in the heart and blood vessel function and, the respiratory organs function, qualities in speed and jumping. (2) the athletes who are preparing for national competition are better than those preparing for provinceial competition and being out of in the field in physical Morphology such as the length and surround of limbs and, lean body mass, circumference, breath difference, Physiologic Function like the heart function index number, 5-time Vital Capacity, haemoglobin, body Constitution like 50-meter dash, quatre run, 20x5-meter shunt run, 1500-meter run, the rope skipping of 3-minute, standing long jump, the...
