Contractile properties of the pigeon supracoracoideus during different modes of flight
(The Company of Biologists, 2008)The supracoracoideus (SUPRA) is the primary upstroke muscle for avian flight and is the antagonist to the downstroke muscle, the pectoralis (PECT). We studied in vivo contractile properties and mechanical power output of ... -
Different Segments within Vertebrate Muscles Can Operate on Different Regions of Their Force–Length Relationships
(Oxford University Press (OUP), 2018-06-13)To relate in vivo behavior of fascicle segments within a muscle to their in vitro force-length relationships, we examined the strain behavior of paired segments within each of three vertebrate muscles. After determining ... -
In vivo force-length and activation dynamics of two distal rat hindlimb muscles in relation to gait and grade
(The Company of Biologists, 2019-11-21)Muscle function changes to meet the varying mechanical demands of locomotion across different gait and grade conditions. A muscle's work output is determined by time-varying patterns of neuromuscular activation, muscle ... -
Morphological and kinematic basis of the hummingbird flight stroke: scaling of flight muscle transmission ratio
(The Royal Society, 2011)Hummingbirds (Trochilidae) are widely known for their insect-like flight strokes characterized by high wing beat frequency, small muscle strains and a highly supinated wing orientation during upstroke that allows for lift ... -
Myogenic regulatory transcription factors regulate growth in rhabdomyosarcoma
(eLife Sciences Publications, Ltd, 2017)Rhabdomyosarcoma (RMS) is a pediatric malignacy of muscle with myogenic regulatory transcription factors MYOD and MYF5 being expressed in this disease. Consensus in the field has been that expression of these factors likely ... -
Post-activation muscle potentiation and its relevance to cyclical behaviours
(The Royal Society, 2020-06)Muscle can experience post-activation potentiation (PAP), a temporary increase in force and rate of force development, when contractions are closely timed; therefore, cyclical behaviors are likely affected by PAP, as ... -
Speed-dependent intrinsic caudal fin muscle recruitment during steady swimming in bluegill sunfish, Lepomis macrochirus
(The Company of Biologists, 2008)There are approximately 50 muscles that control tail fin shape in most teleost fishes, and although myotomal muscle function has been extensively studied, little work has been done on the intrinsic musculature that controls ... -
Task-Dependent Recruitment Across Ankle Extensor Muscles and Between Mechanical Demands Is Driven by the Metabolic Cost of Muscle Contraction
(The Royal Society, 2021-01-06)The nervous system is faced with numerous strategies for recruiting a large number of motor units within and among muscle synergists to produce and control body movement. This is challenging, considering multiple combinations ...
