Energy expenditure during stepping.
Previous studies from this department have emphasized the wide variations occurring amongst healthy young adults, both in the daily intake of energy as judged by records of food consumption, and in energy expenditure recorded by indirect calorimetry, for a set task such as walking under standard conditions (Kitchin and others, 1949; Delbue and others, 1949). Although no correlation was demonstr...
متن کاملEnergy expenditure during overfeeding
The large inter-individual variation in weight gain during standardized overfeeding together with a weight gain that is often less than theoretically calculated from the energy excess suggest that there are differences between persons in the capacity to regulate energy expenditure and hence metabolic efficiency. Adaptive thermogenesis is defined as the regulated production of heat in response t...
متن کاملEnergy Expenditure at Rest and During Exercise
The immediate source for muscle contraction is delivered from splitting of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and a ‘free’ phosphate ion (P). This reaction is very fast and does not normally limit energy turnover andmuscle performance. However, the ATP stores in the muscles are very limited. The whole ATP pool would be emptied in only a few seconds of muscle contraction...
متن کاملDiminution in energy expenditure during lactation.
Energy expenditure at rest and in response to a meal and to an infusion of noradrenaline was measured in 12 lactating women and compared with that in seven bottle feeding women and seven non-pregnant, non-lactating controls. The energy response of the lactating women was remeasured after lactation stopped. During lactation the resting metabolic rate was unaltered but there was a reduced respons...
متن کاملEnergy expenditure during submaximal walking with Exerstriders.
This study was designed to determine whether Exerstriding, a modified form of walking using walking sticks (Exerstriders), resulted in an augmented cardiorespiratory response and a greater energy expenditure than when walking without Exerstriders. Female subjects (23.6 +/- 4.0 yr; 58.5 +/- 5.5 kg) completed two randomly assigned trials of treadmill walking (6.7 km.h-1; 0% grade; 30 min.) with (...
