Subjects were 30 six-grade boys and divided into three groups: interval training group (I group, n=10), repetition training group (R group, n=10), and control group (n=10). Both I and R groups received their training three times a week for 12 weeks. The training content for the I group were 4×100-meter runs (400 meters in total). Subjects took active but shorter rests. For R group, subjects run for 400 meters, took rests till their heart rates recover to baseline, and then run again for the second time. Training intensity for the two groups will increase gradually. The intensity comes from 3 sets to 5 sets of runs. Records on the 60, 100, and 200 meter springs, anaerobic capacity, and body components were test before and after the training period in all subjects. The data were analyzed by two way analysis of variance (group × time) with repeated measures to examine any changes after training. We found that I group and R group were significantly increased on the records of 60, 100 and 200 meters springs.（60 meters：10.5±0.8 vs.10.3±0.7；10.7±0.8 vs.10.3±0.5 seconds.100 meters：18.7±1.5 vs.16.6±1.2；19.2±1.8 vs.17.2±1.7 seconds.200 meters：41.4±2.3 vs.37.4±3.6；41.8±2.7 vs.37.5±3.3 seconds, p＜.05）. There were significantly increased on peak anaerobic power by Wingate’s 30 second test (I：446.1±102.2 vs.557.9±154.4；R：463.9±114.9 vs. 576.4±131.1 watt, p＜.05). There were significantly increased on fat free mass and bone mineral content by Inbody 720 test (fat free mass：34.7±5.2 vs.36.4±5.9；36.1±5.2 vs. 38.5±5.0；bone mineral content：2.0±0.2 vs.2.1±0.3；2.1±0.3 vs. 2.2±0.3 kilogram, p＜.05). But there were no significantly difference on BMI, body fat mass and the ratio of waist and hip. We concluded that 12 weeks different training method improved primary school boys’ performance on speed of springs, Wingate’s peak anaerobic power, but didn’t improved fat free mass, bone mineral content and weight reduction. To sum up, involving interval and repetition training during physical training of primary students will help to uplift spring scores and gain better health.
