PURPOSE: To compare the pacing profiles of elite track athletes with intellectual impairments (II) and those with Down syndrome (DS) in 400- and 1,500-m track events.
METHODS: The pacing data of 67 elite runners participating in the final 400-m (both genders) and 1,500-m (only males) track events of the Global Games (2023) were analyzed. Runners competed in two classes: a class for runners with II (without DS) and a separate class for runners with DS.
RESULTS: For the 400-m event, male and female runners in both classes decelerated from the first segment (0-200 m) to the second segment (200-400 m) as the time main effect was significant (p < .001); however, the pacing strategy for both genders differed between the II and DS class as reported by the significant Gender × Class interaction effect (p < .001). The running velocity over the two segments of the race decreased more significantly for the II runners without DS. There was also a significant interaction effect for the 1,500-m race (p < .001). The DS runners show a more significant drop in running velocity over the split times of the race and with more varied fluctuations compared with the II runners without DS.
CONCLUSION: 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.
