Note: Positive means of difference showed an overestimate and the negative mean difference showed an underestimate of ASP estimated values compared to four AG equations estimated each activity. METs: metabolic equivalents, VT: vertical axis, VM: vector magnitude, LoA: limits of agreement. The upper limits of the agreement (high): mean difference + 1.96 standard deviation of the different scores. The limits of the agreement (low): Mean difference −1.96 standard deviations of the different scores. * p < 0.05, ** p < 0.01.
