| Abstract: Objective: To measure and evaluate the physiological function indexes of Shandong excellent free fighting athletes, contrast the characteristics of the physiological function at quiet state and after fixed quantity burden, and provide directive foundation for the material selection and sport exercise. Methods: Measure and contrasting analysis of the indexes of cardio respiratory function (vital capacity, blood pressure at quite state, heart rate before and after burden, function parameters of cardiovascular, maximum oxygen consumption, blood lactate before and after burden), body composition (body fat, percentage of body fat, lean body mass, body weight), urine eight indexes, reaction time (reaction time of left and right hand, of left and right foot, and the harmony time of hands and feet), anaerobic power, flexibility and muscle power of Shandong excellent free fighting athletes(Excellent group, n=27, including 5 master sportsmen and 22 national one-class sportsmen) as well as students of nation traditional free fighting specialty(n=19, all are national two class sportsmen). Results:①Obvious difference of exercise time limits of special item between excellent group and ordinary group. The time limits for master sportsmen is about 6.20±1.48 years while that for one-class free fighting athletes is about 4.55±1.87 years and that for two-class free fighting athletes is about 2.84±0.90 years. ②Either the absolute value (3.59±0.64) or the relative value (48.09±7.16) of the maximum oxygen consumption of the excellent group is higher than that of the ordinary one (absolute value is 43.61±6.79 and relative one is 3.13±0.48)(P<0.05). ③There is no obvious difference of the blood lactate between the excellent and ordinary groups under the quiet conditions while immediately after the quantified load, lower blood lactate is found with the experiment group and the value of blood lactate of the experiment group is 5.22±2.31 while that of the control group is 6.87±2.67)(P<0.05). ④The athlete class is positively correlated with the absolute of the maximum oxygen consumption (r=0.503,P<0.01) while the latter is negatively correlated with blood lactate (r=-0.465,P<0.01). ⑤There is obvious difference of systolic pressure, CO and blood density between the excellent group and the ordinary group. What's more, the SV, CI, SI and so on of the excellent group is higher than that of the ordinary one. ⑥The lean body mass(66.64±11.74) and rate of lean body mass and body fat(8.00±3.20) of the excellent group is much higher than that of the ordinary group(60.83±6.34, 6.20±2.09) (P<0.05). ⑦The change of pH value of the urine of the excellent group (0.33±0.52) has no obvious difference than that of the ordinary group (0.45±0.57) . ⑧There is obvious difference of the reaction time of left hand, left foot and right foot but there is little difference of that of the coordination time. ⑨There is not obvious difference of vital capacity, anaerobic power, standard sit-and-reach, muscular strength etc(P > 0.05). Conclusions: ①The anaerobic energy-providing capacity of excellent free fighting athletes is similar with that of ordinary class ones. However, the aerobic metabolism of the excellent ones is more favorable than that of ordinary ones and the athlete class is positively correlated with the absolute of the maximum oxygen consumption. ②The excellent ones have better cardiac reserve and depend mainly on the increase of the stroke volume to add to the heart output, while the ordinary ones depend mainly on the increase of the heart rate. ③Long regular train has led to lower body fat and rate of body fat of the...
