The biomechanical and metabolic demands of human running are distinctly affected by velocity and body weight. As runners increase velocity, ground reaction forces (GRF) increase, which may increase the risk of an overuse injury, and more metabolic power is required to produce greater rates of muscular force generation. Running with weight support attenuates GRFs, but demands less metabolic power than normal weight running. We used a recently developed device (G-trainer) that uses positive air…

Effect of Body-Weight-Support Running on Lower-Limb Biomechanics.

Clinicians must be aware of lower-limb kinematic alterations to provide safe and effective parameters for rehabilitation involving LBPP treadmills, resulting in reduced ankle and knee joint range of motion.

Muscle Activation and Estimated Relative Joint Force During Running with Weight Support on a Lower-Body Positive-Pressure Treadmill.

It was concluded that leg muscle activation adapted to the new biomechanical environment, and the effect of unweighting on estimated knee force was more pronounced than on ankle force.

Effect of speed and gradient on plantar force when running on an AlterG® treadmill

Maximum plantar force peaks are larger with faster running and smaller with more AlterG® assisted bodyweight support (athlete unweighing), while negative gradients made little difference except for a downhill grade of − 5% decreasing force peaks as compared to level or uphill running.

Physiological and Biomechanical Responses of Highly Trained Distance Runners to Lower-Body Positive Pressure Treadmill Running

Male and female distance runners have similar physiological and biomechanical responses to running on lower-body positive pressure treadmills, and the biomechanicals changes during LBPPT running contributed to less metabolic cost and corresponding physiological changes.

Metabolic accommodation to running on a body weight-supported treadmill

The existence and length of a metabolic accommodation period to running on a lower body positive pressure (LBPP) treadmill was evaluated and the accommodation effect was the largest at the greatest level of body weight support.



Metabolic cost of generating horizontal forces during human running.

The data suggest that generating horizontal propulsive forces constitutes more than one-third of the total metabolic cost of normal running.

Effects of independently altering body weight and body mass on the metabolic cost of running

The results show that generating force to support body weight is the primary determinant of the metabolic cost of running.

Ground reaction forces at different speeds of human walking and running.

There is a change with speed in the complex interaction between vertical and horizontal forces needed for propulsion and equilibrium during human locomotion in walking and running.

Energetics of bipedal running. I. Metabolic cost of generating force.

The results support the idea that the cost of muscular force production determines the energy cost of running and suggest that bipedal runners use more energy for a given rate of force production because they require a greater volume of muscle to support their body weight.

Ground reaction forces in running: a reexamination.

Kinetic changes with fatigue and relationship to injury in female runners.

Habitual female runners appear to adapt their running style with fatigue, resulting in altered GRF, and changes in GRF with fatigue may be associated with lower-extremity running injuries.

Faster top running speeds are achieved with greater ground forces not more rapid leg movements.

It is concluded that human runners reach faster top speeds not by repositioning their limbs more rapidly in the air, but by applying greater support forces to the ground.

The independent effects of gravity and inertia on running mechanics.

Gravity exerted a greater influence than inertia on both vertical and horizontal forces generated against the ground during running, and maintaining the orientation of the resultant vector during periods of high force generation aligns the vector with the leg to minimize muscle forces.
