查询词典 speed limit

The experimental group received 10 weeks of walking exercise training, at 50 minuets per session, 5 days per week and at a exercise intensity limit between 60% and 70% maximum heart rate. The control group received ordinary special education curriculums. All participants completed three times of the PACER（Progressive Aerobic Cardiovascular Endurance Run）20-Meter Shuttle Run test and test for the average walking speed during 1600 meters:before the experiment started , after the experiment and the follow-up test at the fourteenth week of the experiment started. All results from these tests were recorded and analyzed by descriptive statistics; repeated measure t-test; the one way analysis of covariance .
