Was Ability To Run Early Man's Achilles Heel?
ScienceDaily (Sep. 11, 2007) — The earliest humans almost certainly walked upright on two legs but may have struggled to run at even half the speed of modern man, new research suggests.

When to End a Run to Avoid Injury: Runners Change Form When Running Exhausted
ScienceDaily (Dec. 9, 2010) — Runners who continue running when they are exhausted unknowingly change their running form, which could be related to an increased risk for injury. A study by Tracy Dierks, assistant professor of physical therapy at Indiana University, found that toward the end of a normal running session, runners generally displayed an increase in motion in their hips, knees and ankles.

Hip Exercises Found Effective at Reducing, Eliminating Common Knee Pain in Runners, Study Suggests
ScienceDaily (June 5, 2010) — A twice weekly hip strengthening regimen performed for six weeks proved surprisingly effective at reducing -- and in some cases eliminating -- knee pain referred to as patellofemoral pain (PFP) in female runners

Barefoot Running: To Ditch the Shoes or Not?
ScienceDaily (June 7, 2011) — A hot issue among runners is whether running in bare feet reduces or increases the risk of injury. Stuart Warden, associate professor and director of research in the Department of Physical Therapy at Indiana University-Purdue University Indianapolis, says for some runners it could do both.

Why People Choose Running Over Walking
ScienceDaily (Jan. 5, 2012) — Other than Olympic race walkers, people generally find it more comfortable to run than walk when they start moving at around 2 meters per second -- about 4.5 miles per hour.

Running Shoes May Cause Damage to Knees, Hips and Ankles, New Study Suggests
ScienceDaily (Jan. 4, 2010) — Knee osteoarthritis (OA) accounts for more disability in the elderly than any other disease. Running, although it has proven cardiovascular and other health benefits, can increase stresses on the joints of the leg. In a study published in the December 2009 issue of PM&R: The journal of injury, function and rehabilitation, researchers compared the effects on knee, hip and ankle joint motions of running barefoot versus running in modern running shoes. They concluded that running shoes exerted more stress on these joints compared to running barefoot or walking in high-heeled shoes

Barefoot Running: How Humans Ran Comfortably and Safely Before the Invention of Shoes
ScienceDaily (Jan. 27, 2010) — New research is casting doubt on the old adage, "All you need to run is a pair of shoes."

Human Gait Adapted for Efficient Walking at the Cost of Efficient Running
ScienceDaily (Feb. 12, 2010) — Humans, other great apes and bears are among the few animals that step first on the heel when walking, and then roll onto the ball of the foot and toes. Now, a University of Utah study shows the advantage: Compared with heel-first walking, it takes 53 percent more energy to walk on the balls of your feet, and 83 percent more energy to walk on your toes.

Humans Walked On Modern Feet 1.5 Million Years Ago, Fossil Footprints Show
ScienceDaily (Feb. 26, 2009) — Ancient footprints found at Rutgers' Koobi Fora Field School show that some of the earliest humans walked like us and did so on anatomically modern feet 1.5 million years ago.

Science News
Ancient Footprints Show Human-Like Walking Began Nearly 4 Million Years Ago
ScienceDaily (July 19, 2011) — Scientists at the University of Liverpool have found that ancient footprints in Laetoli, Tanzania, show that human-like features of the feet and gait existed almost two million years earlier than previously thought.

Science News
Study Identifies Energy Efficiency As Reason For Evolution Of Upright Walking
ScienceDaily (July 16, 2007) — A new study provides support for the hypothesis that walking on two legs, or bipedalism, evolved because it used less energy than quadrupedal knucklewalking

Science News
Long Legs Are More Efficient, According To New Math Model
ScienceDaily (Mar. 12, 2007) — Scientists have known for years that the energy cost of walking and running is related primarily to the work done by muscles to lift and move the limbs.

Endurance Exercise Linked to Damage in Right Ventricle of Heart
ScienceDaily (Dec. 7, 2011) — Researchers have found the first evidence that some athletes who take part in extreme endurance exercise such as marathons, endurance triathlons, alpine cycling or ultra triathlons may incur damage to the right ventricles of their hearts -- one of the four chambers in the heart involved in pumping blood around the body

'Senior' Runners Never Stop Pushing Their Limits in Marathons
ScienceDaily (Jan. 19, 2012) — Romauld Lepers and Thomas Cattagni, researchers from Inserm Unit 1093 "Cognition, Action and Sensorimotor Plasticity" at the Université de Bourgogone, have analysed changes in participation and performance of runners aged 20 to 80 in the New York marathon over the last 30 years. The results are largely unexpected: the best male marathon runners over 65 and the best female marathon runners over 45 have consistently improved their performance over the last 30 years. At the same time, the researchers also observed a strong increase in athletes over 40 participating in the New York marathon: from 36% of the total masculine runners between 1980-1989, to 53% between 2000-2009; and from 24 to 40% during the same periods for female runners.

The Emerging Fate Of The Neandertals
ScienceDaily (Apr. 23, 2007) — For nearly a century, anthropologists have been debating the relationship of Neandertals to modern humans. Central to the debate is whether Neandertals contributed directly or indirectly to the ancestry of the early modern humans that succeeded them.

Modern Humans Emerged Far Earlier Than Previously Thought, Fossils from China Suggest
ScienceDaily (Oct. 25, 2010) — An international team of researchers, including a physical anthropology professor at Washington University in St. Louis, has discovered well-dated human fossils in southern China that markedly change anthropologists perceptions of the emergence of modern humans in the eastern Old World.
