摘要: ABSTRACTAccelerometers provide a measure of step-count. Reliability and validity step-count pedal-revolution count measurements by the GT3X+ accelerometer, placed at different anatomical locations, is absent in literature. The purpose this study was to investigate reliability step counts produced locations during running bicycling.Twenty-two healthy adults (14 men 8 women) completed bicycling activity bouts (5 minutes each) while wearing 6 accelerometers: 2 each waist, thigh shank. Accelerometer video data were collected activity.Excellent found for taken from accelerometers mounted waist shank (Reliability: intraclass correlation (ICC) ≥ 0.99; standard error measurement (SEM) ≤1.0 steps; Validity: Pearson 0.99) ICC SEM revo...
