Construction of Constant-Load (Isotonic) and Constant-Velocity (Isokinetic) Torque-Velocity-Power Profiles In vivo for the Rat Plantar Flexors

Here, we present a novel protocol to non-invasively measure the torque-angular velocity-power relationship in vivo in rat plantar flexors using transcutaneous muscle stimulation. This setup enables simple testing of isotonic muscle contractions on a force transducer/length controller system to better represent the constant-load nature of everyday movements.

Chemical Kinetics and the Reaction Rate Law Chemical kinetics refers to the rate or speed of a chemical reaction. The rate depends on the mechanism, complexity, and number of reactants in the reaction. Reactant concentration also plays a significant role in the rate of a reaction. The rate law quantifies this relationship through experimentation. Each reactant contributes to the speed of the reaction by a factor known as the reaction order. This factor can range from zero to two, and it depends...

Source: Smaa Koraym at Johns Hopkins University, MD, USA Concentration DependenceExpand In this experiment, you will combine varying concentrations of aqueous HCl and sodium thiosulfate to make solid sulfur, which rapidly gathers into opaque yellow particles at a certain sulfur concentration. Since the reaction solution starts clear and colorless, you can easily tell when it reaches that concentration. You'll use the same test tube and total volume each time, so it will take the same amount...

A concentration cell is a type of a voltaic cell constructed by connecting two almost identical half-cells, both based on the same half-reaction and using the same electrode, differing only in the concentration of one redox species. A concentration cell's potential, therefore, is determined only by the concentration difference of the particular redox species. Consider the following voltaic cell: From the given information, the cell potential of this concentration cell can be calculated using...

Source: Laboratory of Dr. Michael Evans — Georgia Institute of Technology A solution is a homogeneous mixture containing some components in small amounts, called solutes, and one component in a large amount, called the solvent. Solid-liquid solutions contain one or more solid solutes dissolved in a liquid solvent. Solutions are ubiquitous in chemistry: they are used to store and handle small amounts of material, carry out chemical reactions, and develop materials with controllable properties.
FAQs
A preset angular velocity standardizes how quickly the joint moves while the participant produces force. Because resistance accommodates the person’s effort rather than imposing a fixed external load, the participant can continue exerting through the selected range of motion. This produces torque measurements under controlled movement conditions, supporting comparisons between limbs, muscle groups, or repeated assessments.
Accommodating resistance adjusts to the participant’s effort while the dynamometer preserves the selected movement speed. This arrangement allows performance to be recorded across the movement rather than at only one external load condition. The resulting torque and related measures can identify reduced output in a tested muscle group and provide objective information about changes in muscular function.
The tested joint or muscle group, selected range of motion, preset angular velocity, and participant effort all influence interpretation. Keeping these conditions consistent helps distinguish a true change in muscular performance from a difference in the testing setup. Standardization is particularly important when comparing limbs, evaluating functional deficits, or monitoring recovery over time.
A clinician or researcher selects the joint or muscle group and defines the range of motion and preset angular velocity. The participant then performs shortening contractions with maximal effort against the dynamometer’s accommodating resistance. The computerized system records torque and related performance measures, which can later be used to compare performance or assess functional change.
Testing provides objective measurements that can be repeated during rehabilitation. Clinicians can compare the involved and uninvolved limbs or evaluate changes in a muscle group across successive assessments. Differences in torque or related performance measures may indicate persistent functional deficits or improvement, helping monitor recovery and informing treatment planning after injury or surgery.
These measurements quantify aspects of muscular performance under standardized movement conditions. Comparing results across limbs or muscle groups can help identify neuromuscular impairment and functional deficits, while repeated testing can document changes during rehabilitation. In medicine, that information supports treatment planning and provides an objective basis for tracking whether muscular function is changing over time.
