Abstract: The purpose is to establish an individual anaerobic threshold heart rate regression equation for high school boys going for “Sunshine Long Distance Run” via experimental study, so that every student can get an individually suitable load intensity, and therefore control his/her running speed. In phase one, the authors preliminarily selected the indexes through literature, and further screened the preliminarily selected indexes by means of expert questionnaire, and then carried out experimental test on the determined indexes, used anaerobic threshold heart rate as an independent variable and the screened indexes as independent variables for regression, and established an individual anaerobic threshold heart rate regression equation; in phase two, the authors carried out paired samples t test on the anaerobic threshold heart rate calculated by the regression equation and the anaerobic threshold heart rate measured, and carried out back substitution test; in phase three, the authors let the testees have 12-week training by using the anaerobic threshold heart rate calculated by the regression equation as the load intensity, so as to check the practical application effect. The results showed the followings: 1) the results of the paired t test on the predicted values and actually observed values of the testees showed no significant different (P>0.005); the authors carried out correlation analysis on the pre-dicted values and actually observed values, and again verified that their consistency was high (r=0.889, P<0.001); 2) after the 12-week training, the VO2max of the experiment group increased significantly as compared to that before the training (P<0.01), the VO2max of the control group had no significant difference as compared to that before the training (P>0.05); in VO2max comparison, the experiment group’s was significantly higher than the control group’s (P<0.01). The results indicated the followings: using individual anaerobic threshold heart rate as a load intensity monitoring index is recommended for the activity of high school boys going for “Sunshine Long Distance Run”; the individual anaerobic threshold heart rate regression equation is: Y=111.537+6.076×x1－0.2821×x2－0.569×x3+9.944×x4 (where x1 is age, x2 is height, x3 is basic heart rate, x4 is body surface area).
