Popis:	BACKGROUND: Triaxial accelerometer output [Vector Magnitude (VM) counts] may better estimate physical activity intensity as reflected in the rate of oxygen uptake (VO(2)) than the traditional Vertical Axis (VA) counts in adults with Down syndrome (DS). This study examined the accuracy of VM vs. VA counts in estimating V̇O(2) in adults with and without DS across different physical activities and sedentary behaviours. METHODS: Sixteen adults with DS (10 men; 31 ± 15 years) and 19 adults without DS (10 men; 24 ± 5 years) performed 12 tasks. V̇O(2) was measured by portable spirometer (K4b(2), Cosmed) and VM and VA with an accelerometer (wGT3X-BT, Actigraph). RESULTS: VM and VA were significant predictors of V̇O(2) in adults with DS (p
