Dogs and cats make short-term food choices based on palatability. We hypothesized that if palatability were masked, long-term food choices would be based on physiologic requirements, and circulating metabolite concentrations would reflect those choices. Four experimental foods with similar palatability, but varying in macronutrient composition, were prepared for healthy adult dogs (n=17) and cats (n=27). Food 1 was high protein; Food 2 was high fat; Food 3 was high carbohydrates; and Food 4 was balanced for macronutrients...

BACKGROUND: Aging and Parkinson's disease are often associated with impaired postural control. Providing extrinsic feedback via vibrotactile sensation could supplement intrinsic feedback to maintain postural control. RESEARCH QUESTION: We investigated the postural control response to vibrotactile feedback provided at the trunk during challenging stance conditions in older adults at high fall risk and individuals with Parkinson's disease compared to healthy older adults...

This study aimed at determining whether the combination of action observation and motor imagery (AO + MI) of locomotor tasks could positively affect rehabilitation outcome after hip replacement surgery. Of initially 405 screened participants, 21 were randomly split into intervention group ( N = 10; mean age = 64 y; AO + MI of locomotor tasks: 30 min/day in the hospital, then 3×/week in their homes for two months) and control group ( N = 11, mean age = 63 y, active controls). The functional outcomes (Timed Up and Go, TUG; Four Step Square Test, FSST; and single- and dual-task gait and postural control) were measured before (PRE) and 2 months after surgery (POST)...

We investigated age-related differences in the required coefficient of friction (RCOF) during 90° turning, the difference of RCOF during step and spin turn, and how affects observed differences. Sixteen healthy young and healthy older adults (eight men and eight women in each group) participated. Participants performed 90° step and spin turns to the right at a self-selected normal speed. Older adults turned with lower RCOF than the young adults during both step and spin turns. This was associated with reduced mediolateral (ML) RCOF component (RCOFML ) for the older adults...

Insulin is the principal postprandial anabolic hormone and resistance to its action could contribute to sarcopenia. We developed different types of hyperinsulinemic clamp protocols to measure glucose and protein metabolism in insulin resistant states (older adults, obesity, diabetes, etc.). To define effects of healthy aging in response to insulin, we employed the hyperinsulinemic, euglycemic and isoaminoacidemic (HYPER-1) clamp. The net whole-body anabolic (protein balance) response to hyperinsulinemia was lower in the elderly vs young (p = 0...

Achilles tendon stiffness determines calf muscle functioning during functional activities. However, contrasting evidence was found in studies comparing Achilles tendon stiffness in older and younger adults. Therefore, this systematic review compares Achilles tendon stiffness and elastic modulus in older and younger adults and reviews functional implications. Studies revealed by systematic bibliographic searches were included if healthy older adults were investigated and if Achilles tendon stiffness was measured using ultrasound and dynamometry...

One in three older adults falls each year. There are approximately 2.5 million falls among older adults treated in emergency departments. Falls account for 87% of all fractures in this age group. The biggest risk factor for falling is a history of falls. Other risk factors include frailty, sedative and anticholinergic drugs, polypharmacy, and a variety of medical conditions. Current recommendations are that all patients age 65 years and older should be asked about falls each year. Patients also can be screened for fall risk with a variety of approaches including questionnaires and the Timed Up & Go test...

BACKGROUND: Sequence-specific learning (SSL); the ability to implicitly integrate repeated sequences compared to random sequences during a motor sequence paradigm, is impaired in healthy elders (HE) compared to healthy young (HY). Prior studies have provided limited practice (small repetitions and only 1 to 3 days). RESEARCH QUESTION: Using a standing, postural control task we sought to assess if more practice (7 days) would remediate the differences observed in SSL for HE...
