Using pedometers to measure moderate-to-vigorous physical activity for youth with an intellectual disability.

摘要: Abstract Background Pedometers serve as one of the most feasible and cost-effective methods for frontline practitioners to measure moderate-to-vigorous physical activity (MVPA) youth with an intellectual disability (YwID) but, historically, pedometers have been unable MVPA. Technological advancements now allow MVPA via step frequency (steps per minute). Translating output this technology into practical information that families can use, however, will require accurate guidelines. Objective The purpose study was identify steps minute thresholds corresponding YwID. Methods Thirty-eight children adolescents (10 girls, 11.8 ± 1.8 years) attending a summer camp ID walked on treadmill starting at 2.0 mph increasing every 2 minutes by 0.5 until they reached 4.0 mph. Youth were affixed heart rate (HR) monitor. Steps counted trained observers using hand-tally counters. Data collected during final each speed. HR speed transformed percentage reserve (%HRR), participant's resting HR. Percentage HRR 40%HRR or higher used define Random effects models constructed predict from %HRR participant characteristics. Results results indicated that, average, 122 steps·min−1 minimal threshold Height- age-specific ranged 135 112 steps·min−1. Conclusions These findings provide preliminary working YwID use promote evaluate in population.
