A Nov. 12 article on MSNBC cites the research of SMU physiologist and biomechanist Peter Weyand in which he and other scientists found that everyone uses about the same amount of energy when they walk, but short people use more energy over a given distance. The reason: people with shorter legs take more steps to cover the same distance as people with longer legs.
Weyand says the study has clinical applications and weight balance applications. In addition, the military is interested too because metabolic rates influence the physiological status of soldiers in the field, he said.
A study by SMU’s Peter Weyand and colleagues found that tall people walk more economically than short or small people because tall people have longer strides and take fewer steps to cover the same distance.
In a special partnership with NBC Learn, the science magazine set up an imaginary 40-yard dash with the video series, “The Science of NFL Football.” Weyand was posed the question: Imagine a 40-yard dash that races a wide receiver, a safety, an ostrich, an elephant and a pig — who would win? Read the excerpt for Weyand’s answer.
An article looking at the abilities of humans and animals to run long distances tapped into the research of SMU physiologist and biomechanist Peter Weyand.
Journalist Brian Resnick in Popular Mechanics cites Weyand’s knowledge to explain the differences at work between humans and animals in “The Animal Kingdom’s Top Marathoners.” Weyand is an SMU associate professor of applied physiology and biomechanics in the Annette Caldwell Simmons School of Education & Human Development.
Jamaican sprinter Usain Bolt‘s record-setting performances have unleashed a wave of interest in the ultimate limits to human running speed. A new study published Jan. 21 in the Journal of Applied Physiology offers intriguing insights into the biology and perhaps even the future of human running speed.
The newly published evidence identifies the critical variable imposing the biological limit to running speed, and offers an enticing view of how the biological limits might be pushed back beyond the nearly 28 miles per hour speeds achieved by Bolt to speeds of perhaps 35 or even 40 miles per hour.
The new paper, “The biological limits to running speed are imposed from the ground up,” was authored by Peter Weyand of Southern Methodist University; Rosalind Sandell and Danille Prime, both formerly of Rice University; and Matthew Bundle of the University of Wyoming.
The artificial lower limbs of double-amputee Olympic hopeful Oscar Pistorius give him a clear and major advantage over his competition, taking 10 seconds or more off what his 400-meter race time would be if his prosthesis behaved like intact limbs.
