Abstract: Advanced age has been shown to result in decreased compliance, shortening velocity, and calcium sensitivity of the heart muscle. Even though cardiac health has been studied extensively in elderly populations, relatively little is known about… read more here.

DOI: 10.1086/722449
Abstract: Muscle contractile properties are dependent on temperature: cooler temperatures generally slow contractile rates. Contraction and relaxation are driven by underlying biochemical systems, which are inherently sensitive to temperature. Carollia perspicillata, a small Neotropical bat, experiences… read more here.

DOI: 10.14814/phy2.15541
Abstract: This study evaluated the maximal fascicle shortening velocity under near‐no‐load conditions. In addition, we determined whether the rate of torque development during ballistic contraction was related to maximal fascicle shortening velocity. Under passive and active… read more here.
