, moderate, and vigorous activity. Resting metabolic rate decreases with age, whereas the energy costs associated with even simple activities such as walking to the bathroom increase with age. Consequently, the traditional use of Freedson cut points, as was used in the Actigraph studies, may result in an

state were calculated. Resting V ˙ O 2 was calculated, and the metabolic equivalent of task (MET) for each condition was calculated by dividing the V ˙ O 2 per condition by the average V ˙ O 2 during lying of each individual participant (ie, resting metabolic rate). Muscle activity was expressed

through MET values, that is, the ratio of an individual’s working metabolic rate relative to her or his resting metabolic rate. MET values are well documented in the Compendium of Physical Activities and include 4 basic PA intensities: sedentary ≤1.5 METs, light intensity 1.6 to 2.9 METs, moderate

metabolic rate], which was then divided by 365 to obtain an average daily EE for each activity: Average daily EE for activity   i = ( frequency i × 4 × duration i × MET i ) / 365 . These estimates of the average daily EE for each activity were then summed, resulting in an overall estimate of respondents

This PA questionnaire uses the metabolic equivalent intensity values, defined as the ratio of the metabolic rate during an activity to a standard resting metabolic rate of 1.0 (4.184 kJ) per

resting metabolic rate and/or increased capacity for glucose and free fatty acid clearance may represent mechanisms explaining beneficial metabolic adaptations with higher muscle fitness. 36 Another potential mechanism, supported by the removal of most of the statistically significant associations when

G cutoff points and MET thresholds had a strong agreement for PB intensity identification (Cohen’s κ = 0.81; 95% CI, 0.49 to 1.31; P  < .001). To help account for individual differences in physical fitness, 1 MET was equal to the resting metabolic rate of the participant. Participants were provided

Indeed, based on the current cross-sectional analysis, it appears
