“…Basal metabolic rate (BMR) was determined as the mean metabolic rate between 0715 and 0800. Coefficient of variation (CV) for BMR over 3 days was 1.7% as previously reported [11]. Prescribed physical activity in L-day consisted of 30 min of walking at 3.2 km/h, 30 min of walking at 5.6 km/h, and 15 min of jogging at 8.0 km/h.…”

BackgroundAlthough physical activity recommendations for public health have focused on locomotive activity such as walking and running, it is uncertain how much these activities contribute to overall physical activity level (PAL). The purpose of the present study was to determine the contribution of locomotive activity to PAL using total step counts measured in a calorimeter study.MethodsPAL, calculated as total energy expenditure divided by basal metabolic rate, was evaluated in 11 adult men using three different conditions for 24-hour human calorimeter measurements: a low-activity day (L-day) targeted at a low active level of PAL (1.45), and a high-frequency moderate activity day (M-day) or a high-frequency vigorous activity day (V-day) targeted at an active level of PAL (1.75). These subjects were permitted only light activities except prescribed activities. In a separate group of 41 adults, free-living PAL was evaluated using doubly-labeled water (DLW). In both experiments, step counts per day were also measured using an accelerometer.ResultsIn the human calorimeter study, PAL and step counts were 1.42 ± 0.10 and 8,973 ± 543 steps/d (L-day), 1.82 ± 0.14 and 29,588 ± 1,126 steps/d (M-day), and 1.74 ± 0.15 and 23,755 ± 1,038 steps/d (V-day), respectively. In the DLW study, PAL and step counts were 1.73 ± 0.15 and 10,022 ± 2,605 steps/d, and there was no significant relationship between PAL and daily step counts.ConclusionsThese results indicate that an enormous number of steps are needed for an active level of PAL if individuals extend physical activity-induced energy expenditure by only locomotive activity. Therefore, non-locomotive activity such as household activity should also play a significant role in increasing PAL under free-living conditions.

“…The gold standards to measure energy expenditure (EE) are direct calorimetry and doubly labeled water (Ohkawara et al 2008;Snodgrass et al 2006). In addition to their very expensive and unsuitable use for everyday purposes, these two methods have the major disadvantage of offering no information on the frequency and intensity of the spontaneous activity of individuals.…”

To validate a new device designed to measure ventilation (V(E)), tidal volume (V(T)), inspiratory time (T(I)), and expiratory time (T(E)) during daily life activities. The anteroposterior displacement of the rib cage and abdomen and the axial displacements of the chest wall and the spine were measured using two pairs of magnetometers. was estimated from these four signals, and was simultaneously measured using a spirometer. A total of 707, 732, and 1,138 breaths were analyzed in sitting, standing, and exercise conditions, respectively. We compared V(E), V(T), T(I), and, T(E) measured by magnetometers (V(E)mag, V(T)mag, T(I)mag, and T(E)mag) with V(E), V(T), T(I), and T(E) measured by a spirometer V(E)spiro, V(T)spiro, T(I)spiro, and T(E)spiro, respectively). For pooled data V(E)mag, V(T)mag, T(I)mag, and T(E)mag were significantly correlated (p < 0.001) with V(E)spiro, V(T)spiro, T(I)spiro, and T(E)spiro in sitting and standing positions and during the walking exercise. The mean differences, between V(E)mag, and V(E)spiro for the group, were 10.44, 10.74, and 12.06% in sitting, standing, and exercise conditions, respectively. These results demonstrate the capacity of this new device to measure V(E) with reasonable accuracy in sitting, standing, and exercise conditions.

“…When we discuss issues concerning total EE induced by exercise, we need to investigate not only duration of the exercise, but also the post-exercise recovery period. During this period, there is a remarkable increase in EE due to the excess post-exercise energy expenditure (EPEE) ( 15 ), also known as the excess post-exercise oxygen consumption (EPOC) ( 4,9 ). Many studies ( 2,6,9 ) have revealed that exercise intensity impacts the magnitude of EPEE.…”
