• Resumen

  • The purpose of this study was to twofold: to determine reliability of peak performance as measured by peak heart rate (HRpeak) during the Progressive Cardiovascular Endurance Run (PACER) and a treadmill stress test (TM); and to compare the PACER and the TM. The sample consisted of 42 participants 8 to 21 years old with mild mental retardation. Participants completed two PACERs followed by two TMs separated by a minimum of 48 hr. Data collected were: HRpeak for the PACER and TM; PACER laps completed; and TM endurance time (min). Intraclass correlations were computed separately for males and females in order to assess the reliability of PACER laps, HRpeak, and TM time. Results indicated high reliability for both males and females on PACER laps and TM HRpeak and for males on PACER HRpeak and TM time; moderate reliability was observed for females on PACER HRpeak and TM time. No significant differences were detected within or among trials. These findings indicate that youth with mild mental retardation exhibit consistent peak performance on the PACER and TM tests; therefore, PACER can be used for surveillance of aerobic fitness in this population
