A new paper on guinea fowl gait biomechanics for National Biomechanics Day! 

How do bipedal animals adjust movement to avoid falls in slippery terrain? We found that guinea fowl slow down, take shorter steps and adjust posture to reduce fall risk in slippery terrain, just like humans.

How does menopause impact muscle strength?💪

Research by Dr. Geoff Power and PhD grad Dr. Parastoo Mashouri from Human Health Sciences shows that muscles can change in surprising ways, with some even becoming stronger.

I love a good story about persistent inward currents (PICs).

But I’ve always wondered: could other ion channels contribute to the motoneuron firing behaviours we usually attribute to PICs?

Our new preprint suggests the answer might be yes.

The death of Alan Wilson is an enormous loss to comparative biomechanics. He was a visionary who pushed the envelope of technology to enable rigorous measures of movement and physiology of wild animals. He lifted the entire field by pushing us to address big, integrative questions.

Aging muscles and tendons are less efficient (anyone of a certain age knows that!). New research shows older adults use more energy for basic leg/joint movements than younger people. Read more in APS Publications Journal of Applied Physiology: https://ow.ly/OriN50Y0cCI #ArticlesInPress 🧪

Older adults produce joint moments less economically than young adults | Journal of Applied Physiology | American Physiological Society Older adults expend more metabolic energy than young adults during walking (worse walking economy). Amid the numerous physiological changes that accompany advanced aging, the mechanisms governing the age-related decline in walking economy remain unestablished. Due to conflicting evidence, we studied whether older adults produce lower-limb joint moments less economically than young adults, independent of an age-related difference in muscle co activation. Eight older adults (71.6 ± 6.0 years) and 13 young adults (23.1 ± 4.7 years) repeatedly produced hip and ankle moment cycles on a dynamometer following visual feedback and an audible metronome. We instructed participants to produce moments with peak net torque values of 20 and 30 Nm at a 0.75 Hz cycle frequency and a 0.5 duty cycle. Overall, young and older adults did not co-activate their antagonist muscles differently during the moment production trials. At the hip, older adults expended more metabolic power than young adults despite producing lower moment amplitudes. At the ankle, older adults expended more metabolic power than young adults while producing non-different moment production cycles. Because older adults produced lower-limb joint moments less economically than young adults, interventions aimed at prolonging youthful walking economy into advanced age may need to directly address changing muscle-tendon unit physiology.
