Describe 3 biomechanical factors that influence muscle force production. Be sure to explain how or why force would increase/decrease, and itemize your answer.

Please help in answering this question on toadfish physiology and muscle contractions.

Discuss the functions of muscle proteins (8 or more) and give an example for each.

Muscle fatigue is assessed by which of the following direct measures? O a. Mean Power Output O b. Muscle lactate concentration O c. Muscle glycogen concentration d. Electromyography

Select all correct answers (i.e. more than one answer may be correct). What is the advantage of having a muscle with a bipennate muscle fiber orientation rather than a longitudinal fiber orientation? Assume that the general muscle volume is held constant between orientation types. Obipennate muscle has a smaller physiological cross-sectional area Obipennate muscle has larger force-producing capabilities Obipennate muscle has a greater muscle shortening capability

Order the events leading to muscle contraction. Ca ions bind to troponin myosin binds to actin Nerve cell releases acetylcholine at the neuromuscular junction troponin pulls tropomyosin, exposing the mysoin binding site ATP causing myosin to move (pull) actin toward the center of the cell the sarcolemma membrane depolarizes and triggers the sarcoplamic reticulum to release Ca ions

There are many methods for testing muscle strength. Which in the list below are tests of isometric muscle strength?     Select 2 correct answer(s)     Computer-assisted testing   Cable tensiometry   Dynamometry   One Rep Max

Please help with the labeling of organization of skeletal muscle: Here's what  I found: fascicle muscle fibers nuclei sarcomere sarcolemma myofibril M line I band A band Z disc H zone Thick filament Thin filament perimysium sarcoplasmic reticulum epimysium

What are 3 research-based methods to test for fast- versus slow-twitch muscle fibers?   Select 3 correct answer(s)     Bicep curl repetitions   Vertical jump   Muscle biopsy   Long jump   80% 1RM

Describe what is happening overall in the first sentence. Then describe, in detail, what is happening in each step below. Include details about what is happening at steps 5 - 7 in terms of calcium and the contraction mechanism (from a different figure).
