Understanding Why Kids Get Tired Much Faster Than Adults During a Walk
Peter Weyand from Southern Methodist University and his team have discovered the equation for how much energy we use while walking.
They have linked the effect that body size has on physiological function.
"This goes back to Max Kleiber's work on resting metabolic rates for different sized animals. He found that the bigger you are the slower each gram of tissue uses energy," explained Weyand.
Intrigued by the question of why smaller people use more energy per kilogram body mass than larger individuals when walking, Weyand and colleagues decided to measure the metabolic rates of children and adults, to try to find out why larger people are more economical walkers than smaller people.
They found that walkers of all heights use the same amount of energy per stride, making short people less economical because they take more steps.
They also derived a fundamental equation to calculate exactly how much energy walkers use with direct applications in all walks of life.
First Weyand and colleagues filmed male and female volunteers as they walked on a treadmill. Meanwhile, they simultaneously measured the walkers' oxygen consumption and carbon dioxide production rates to obtain their total metabolic rate.
Next the team calculated the amount of energy that each person used for walking by subtracting the basal metabolic rate from the total metabolic rate measured while walking.
