Fuel-Powered Artificial Muscles
Science, 2006Artificial muscles and electric motors found in autonomous robots and prosthetic limbs are typically battery-powered, which severely restricts the duration of their performance and can necessitate long inactivity during battery recharge. To help solve these problems, we demonstrated two types of artificial muscles that convert the chemical energy of ...

Sarcopenia, as defined by the European working group on sarcopenia in older people (EWGSOP), is a highly prevalent syndrome characterized by age-related loss of muscle mass and muscle strength/power with impacts on physical function, health and quality of life in older people.

Force-velocity, force-time, and force-length relations of muscle are typically evaluated with reductionist techniques in which force is measured while the variable of interest is manipulated. However, force produced during voluntary movement arises from complex interaction of these contractile characteristics. Nonetheless, neuromuscular performance for

Endurance training enhances the oxidative capacity of skeletal muscle by stimulating the production of mitochondria, the organelles that supply fuel to cells. The molecular signals that mediate this adaptive process are not well understood.

Is your horse not performing quite as well as it can? Do you feel as though ‘it's just not right’ but there isn't anything specific that you can put your finger on? Chartered ACPAT physiotherapist Louise Carson investigates the symptoms and possible causes

Powerful signals for weak muscles
Ageing Research Reviews, 2009The aim of the present review is to summarise, evaluate and critique the different mechanisms involved in anabolic growth of skeletal muscle and the catabolic processes involved in cancer cachexia and sarcopenia of ageing. This is highly relevant, since they represent targets for future promising clinical investigations.

Dissecting muscle power output
Journal of Experimental Biology, 1999ABSTRACT The primary determinants of muscle force throughout a shortening–lengthening cycle, and therefore of the net work done during the cycle, are (1) the shortening or lengthening velocity of the muscle and the force–velocity relationship for the muscle, (2) muscle length and the length–tension relationship for the muscle, and (3 ...

Skeletal Muscle-powered Circulatory Assistance: Muscle Conditioning
[1990] Proceedings of the Twelfth Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005Here we report our experiences on the construction of a skeletal muscle pumping chamber (SMPC) of a biomechanical cardiac assist device made in situ with the Latissimus Dorsi (LD) of sheep. Main results are : i) its feasibility, ii) its long-standing continuous contractile activity. From the end of the three-week conditioning the SMPC is activated 24 h

If the physiology of muscular contraction is reviewed in the light of internal muscle mechanics, a new approach to the physiology of tendon surgery is opened. Certain internal rearrangements must occur in the structure of the muscle after its range has been lengthened, shortened or changed.

Bradykinesia, muscle weakness and reduced muscle power in Parkinson's disease
Movement Disorders, 2009AbstractMuscle power (force × velocity) could clarify the relationship between weakness and bradykinesia in Parkinson's disease (PD). The aims of this study were to determine if patients with PD were weaker and/or less powerful in their leg extensor muscles than a neurologically normal control group and to determine the relative contributions of force ...
