The Independence Effects Of Gravitational And Inertial Forces On Gait Transitions In Humans, Nathan Frakes
The Independence Effects Of Gravitational And Inertial Forces On Gait Transitions In Humans, Nathan Frakes
Cal Poly Humboldt theses and projects
The Dynamic Similarity hypothesis suggests gravitational and inertial forces plays a role in determining preferred transition speed (PTS) for walk to run transitions (WRT) and run to walk transitions (RWT), and that humans prefer to transition gait when the ratio of inertial force (IF) to gravitational force (GF) (i.e. Froude #) is ~0.5. Purpose: To investigate the effect of gravitational and inertial forces on PTS, Froude # (Fr) and kinematics for both WRT and RWT. Methods: Twelve healthy adults (9 M, 3 F) performed WRT and RWT trials on a treadmill across seven combinations of altered body weight (BW) and …
The Effect Of Postural Alterations On Metabolic Cost In Running On Incline Slopes, Nikaela K. Hemminger
The Effect Of Postural Alterations On Metabolic Cost In Running On Incline Slopes, Nikaela K. Hemminger
Cal Poly Humboldt theses and projects
In spite of an intuitive relationship between running technique and performance, the influence of specific techniques on metabolic cost remains unclear. While recent studies suggest that postural lean affects metabolic cost during level ground running, little information exists regarding the influence of postural lean on the metabolic cost of running on an incline slope. Purpose: This study sought to investigate the effect of postural lean on metabolic cost, kinematics, and muscle activation of running across a range of incline slopes. Methods: Sixteen healthy adult runners (21±2 years, 8M/8F) of different competitive standards participated in twelve running trials on a motorized …
