... and EOTS were only moderately correlated. Although EOTS correlated with HROTS, EOTS was not predicted accurately by heart rate on an individual basis. On an applied note, the walk–run gait transition on inclines is of great interest to competitive trail/mountain runners, who often ponder whether...

... freely over natural terrain are consistent with previous lab-based measures of locomotion. Nonetheless, ostriches, like humans, exhibit a gait-transition hysteresis that is not explained by steady-state locomotor dynamics and energetics. Further study is required to understand the dynamics of gait...

...-load’ hypothesis of the WRT. Mechanical parameters that provide an acute signal (peak moment and peak power) were more strongly associated with the gait transition than parameters that reflect the mechanical function across a portion of the stride. We found that both the ankle (peak instantaneous joint...

Hreljac( Hreljac et al., 2001 ) deduced that dorsiflexor overexertion is an important trigger of the gait transition based on increased peak muscle activity and ankle angular acceleration during fast walking. Typically, when subjects walk at their preferred transition speed...

.... In this study we evaluated the effect of carrying loads on the locomotor energetics and gait transitions of the rodent Octodon degus running on a treadmill. Metabolic rate and cost of transport increased about 30% with a 20% increment in body mass. This increment was higher than expectations based on other...

The movements of subjects were videotaped, and surface electromyographic activity was recorded from seven major leg muscles. Resultant...
