Biological interactions and manipulative experiments in soft sediments building on the Woodin foundation
Meeting Abstract 45.1 Monday, Jan. 5 10:30 Biological interactions and manipulative experiments in soft sediments: building on the Woodin foundation BELL, S.S.; University of South Florida, Tampa sbell@usf.edu Woodin (1974) presented one of the first studies that employed cages to examine processes organizing faunal community structure in marine soft sediments. Subsequently, Woodin (1978, 1981) highlighted how refuges […]
The effect of activation level on in vivo muscle lengths and velocities do fibers always operate at their optima
Meeting Abstract 45-4 Tuesday, Jan. 5 08:45 The effect of activation level on in vivo muscle lengths and velocities: do fibers always operate at their optima? HOLT, NC*; AZIZI, E; UC Irvine; UC Irvine natalie.c.holt@gmail.com Skeletal muscle fibers can only generate high forces and powers over a narrow range of lengths and velocities. Many morphological and physiological […]
Temperature dependence of muscle work is determined by load
Meeting Abstract 45-2 Tuesday, Jan. 5 08:15 Temperature dependence of muscle work is determined by load OLBERDING, J.P.*; DEBAN, S.M.; University of South Florida, Tampa; University of South Florida, Tampa jpolberding@mail.usf.edu The temperature dependence of muscle work has implications for whole-organism performance in behaviors involving muscle-powered movements in variable-temperature environments. Behaviors using elastic energy-storage mechanisms are thermally […]
Stretch shortening cycle protocols demonstrate the difference in eccentric properties of EDL and soleus muscles from wild type and mdm mice
Meeting Abstract 45-1 Tuesday, Jan. 5 08:00 Stretch shortening cycle protocols demonstrate the difference in eccentric properties of EDL and soleus muscles from wild type and mdm mice. HESSEL, AL*; NISHIKAWA, KC; Northern Arizona University, Flagstaff AZ alh385@nau.edu https://alhlabbench.wordpress.com/tag/salamanders/ During animal movement, muscle length oscillations are common. We used a stretch-shortening cycle (SSC) protocol that stimulated muscles […]
Skeletal muscle architecture determines propensity for muscle damage during eccentric contractions
Meeting Abstract 45-3 Tuesday, Jan. 5 08:30 Skeletal muscle architecture determines propensity for muscle damage during eccentric contractions ABBOTT, E.M.*; AIKHIONBARE, I.; AZIZI, E.; Univ. of California, Irvine abbotte@uci.edu Skeletal muscles not only accelerate our bodies during movement, they also play a crucial role in deceleration. During decelerating tasks, such as landing and braking, muscles are stretched […]
Muscle Dynamics During Level and Incline Hopping
Meeting Abstract 45-7 Tuesday, Jan. 5 09:30 Muscle Dynamics During Level and Incline Hopping MCGOWAN, C.P.; University of Idaho cpmcgowan@uidaho.edu http://www.webpages.uidaho.edu/McGowanLab/ Bouncing gaits such as running, trotting and hopping are believed to be efficient because they enable animals to utilize elastic energy storage and recovery, much like a bouncing ball. However not all bipedal hoppers have compliant […]
Effects of aging and exercise on musculoskeletal performance in two genetic strains of the house mouse, Mus musculus domesticus
Meeting Abstract 45-6 Tuesday, Jan. 5 09:15 Effects of aging and exercise on musculoskeletal performance in two genetic strains of the house mouse, Mus musculus domesticus BEECHKO, A/N*; GHOSSEIN, N; HORNER, A; GARLAND, T; AZIZI, M; California State University, San Bernardino; California State University, San Bernardino; California State University, San Bernardino; University of California, Riverside; University of […]
Does aponeurosis influence the relationship between muscle gearing and force
Meeting Abstract 45-5 Tuesday, Jan. 5 09:00 Does aponeurosis influence the relationship between muscle gearing and force? ENG, CM*; ROBERTS, TJ; Brown University; Brown University carolyn_eng@brown.edu Muscle shape changes in pennate muscles affect the force and speed of contraction because they influence the gear ratio through which muscle fibers transmit force and speed to the whole muscle. […]
