Performance and Pacing Profiles of Competitive Track Events for Elite Athletes With Intellectual Impairment With and Without Additional Significant Impairments

This study highlights the significant differences in pacing between 400- and 1,500-m elite runners with II and with and without DS. Elite runners with DS run at an overall slower velocity and follow a significantly different pacing pattern compared with runners with II without DS. Our findings show that runners with DS are less able to regulate their exercise intensity over the race than runners with II without DS.
