C. elegans have two types of muscles, single sarcomere and multiple sarcomere, or striated muscles. This video describes the arrangement of the striated body wall muscles, which are responsible for a worm’s locomotion and includes a sample protocol to measure muscle morphology using image analysis software.

Survivors of acute respiratory distress syndrome (ARDS) and critical illness frequently develop long-lasting muscle weakness. Manual muscle testing (MMT) is a standardized clinical examination commonly used to measure strength of peripheral skeletal muscle groups. This video demonstrates MMT using the 6-point Medical Research Council scale.

We have developed a device (Twister) to study the regulation of tonic muscle activity during active postural maintenance. Twister measures torsional resistance and muscular responses in standing subjects during twisting of the body axis. The device can be flexibly configured to study various aspects of tonic control across the neck, trunk, and/or hips.

We describe a protocol to sample, preserve, and section intact roots and the surrounding rhizosphere soil from wetland environments using rice (Oryza sativa L.) as a model species. Once preserved, the sample can be analyzed using elemental imaging techniques, such as synchrotron X-ray fluorescence (XRF) chemical speciation imaging.
FAQs
The central target is the balance between muscle-protein synthesis and breakdown. A preservation strategy seeks to reduce the excess breakdown or support synthesis that can occur when normal growth or activity is limited. Tracking protein turnover therefore helps researchers determine whether an intervention is acting on the biological processes underlying muscle loss rather than only changing its visible effects.
Mechanical loading provides a controlled condition for examining how activity-related signals affect skeletal muscle. When loading is reduced, researchers can study preservation strategies under conditions that resemble limited activity or immobilization; when loading is included, they can evaluate its contribution alongside nutritional support, rehabilitation, or other interventions. This comparison helps separate the effects of individual conditions.
Sufficient nutritional support can be tested as one component of a preservation strategy because muscle maintenance depends on the relationship between protein synthesis and breakdown. Researchers may examine nutrition alone or in combination with mechanical loading and rehabilitation. Comparing these conditions shows whether nutritional support helps maintain tissue size, strength, function, or protein turnover during restricted activity.
Effectiveness is evaluated through complementary outcomes rather than a single measurement. Tissue size indicates whether muscle mass has been maintained, force testing assesses strength, and protein-turnover measurements examine underlying synthesis and breakdown. Together, these readouts can reveal whether a strategy preserves physical capacity and biological muscle maintenance, even when changes in one outcome are modest.
A typical evaluation establishes a condition in which normal growth or activity is limited, applies a defined preservation intervention, and then compares outcomes with an appropriate experimental condition. Researchers measure tissue size, force, and protein turnover to assess the result. Using several outcomes connects structural preservation with functional performance and the processes that regulate muscle tissue.
These methods are relevant when investigators need to examine muscle wasting or protect function during aging, illness, immobilization, or recovery. They can be used to test treatments under experimentally controlled conditions and to study how skeletal muscle responds when ordinary activity is disrupted. The resulting measurements help connect biological changes with preserved or reduced physical capacity.
During recovery research, investigators can compare rehabilitation or other controlled interventions with the condition produced by reduced activity. Measurements of muscle size, force, and protein turnover indicate whether recovery restores tissue characteristics, functional strength, and balanced muscle maintenance. This biology-focused approach helps evaluate not only whether muscle appears preserved, but also whether its capacity and underlying regulation improve.
