Applied horizontal force increases impact loading in reduced-gravity running.

The chronic exposure of astronauts to microgravity results in structural degradation of their lower limb bones. Currently, no effective exercise countermeasure exists. On Earth, the impact loading that occurs with regular locomotion is associated with the maintenance of bone's structural integrity, but impact loads are rarely experienced in space. Accurately mimicking Earth-like impact loads in...

Humans Running in Place on Water at Simulated Reduced Gravity

BACKGROUND On Earth only a few legged species, such as water strider insects, some aquatic birds and lizards, can run on water. For most other species, including humans, this is precluded by body size and proportions, lack of appropriate appendages, and limited muscle power. However, if gravity is reduced to less than Earth's gravity, running on water should require less muscle power. Here we u...

Exploring dynamic similarity in human running using simulated reduced gravity.

The Froude number (a ratio of inertial to gravitational forces) predicts the occurrence of dynamic similarity in legged animals over a wide range of sizes and velocities for both walking and running gaits at Earth gravity. This is puzzling because the Froude number ignores elastic forces that are crucial for understanding running gaits. We used simulated reduced gravity as a tool for exploring ...

A gravity loading countermeasure skinsuit

Despite the use of several countermeasures, significant physiological deconditioning still occurs during long duration spaceflight. Bone loss – primarily due to the absence of loading in microgravity – is perhaps the greatest challenge to resolve. This paper describes a conceptual Gravity Loading Countermeasure Skinsuit (GLCS) that induces loading on the body to mimic standing and – when integr...

Comparison of Ground Reaction Force Components during Running with Running Shoes and Control Shoes in Individuals with Genu Varum

Introduction: Running poses an essential role in maintaining cardiovascular health. However, it has been demonstrated that 2.5 to 38 injuries per 1,000 hours of running can occur. The purpose of this study was to investigate ground reaction forces components during running with running shoes compared to control shoes in individuals with genu varum. Methods: This study was laboratory and semi-e...
