Objective To understand effect of the exercise prescription on reducing sports injuries

so as to guide the reasonable use of exercise prescription in dance sport teaching and training.Method The student were divided into experimental group and teaching group

and after the one-semester training

their results were statistically analyzed.Results Samba injuries ratio is bigger than other projects

and the ratio of the experimental group was significantly lower than the teaching group.The difference was statistically significant（P<0.01）;the rates of muscle injuries

ligament injuries and joint injuries of the experimental group were lower than the ones of the teaching group.The difference was statistically significant（P<0.01）;the rate s of back injuries and ankle injuries of the experimental group were lower than the ones of the teaching group.The difference was statistically significant（P<0.01）.Conclusion Exercise prescription can effectively reduce the ratio of dance sport injuries so the prescription should be applied to teaching dance to reduce injuries and improve fitness effect.
