Training and Competency in Animal Procedures
0 Views •
2026
All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. A Stepwise Approach to Training Proper training and competency in animal procedures are essential to ensure high standards of animal welfare and reliable scientific outcomes. A structured, progressive training approach is...

Extinction Training During the Reconsolidation Window Prevents Recovery of Fear

Cited by 50 •
2012
Conditioned fear can be diminished through an inhibitory process called extinction, but can resurface under conditions such as the passage of time or exposure to stress. Our protocol presents a novel way of preventing fear recovery by introducing extinction during the reconsolidation window (the re-storage phase of a reactivated memory).

Impact Loading

2024
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy. In cases of elastic deformation,...
FAQs
External measures describe the work performed, using variables such as exercise duration, intensity, distance, or volume. Internal indicators show how the organism responds to that work through measures including heart rate, perceived exertion, and biochemical responses. Considering both perspectives helps researchers distinguish a prescribed workload from the physiological stress it actually produces.
Repeated exercise can stimulate biological adaptation, but excessive stress may indicate that the workload exceeds an organism’s capacity for effective recovery. Training Load therefore provides a framework for comparing imposed workloads with physiological responses. This balance helps researchers examine why similar exercise demands may be associated with different recovery patterns, performance outcomes, or risks of excessive stress.
By tracking workload alongside physiological responses, researchers can examine how tissues and physiological systems remodel after repeated exercise. These measurements connect the amount and intensity of activity with biological adaptation, rather than treating performance as an isolated outcome. The approach is useful for studying how repeated stress relates to recovery, tissue responses, and physiological performance.
A study can first record external workload variables, such as exercise duration, intensity, distance, or volume. Researchers can then pair those observations with internal indicators, including heart rate, perceived exertion, or biochemical responses. Comparing the two sets of information allows workloads to be characterized more fully and supports evaluation of physiological stress, adaptation, and recovery.
Researchers can use Training Load when different exercise programs impose different durations, intensities, distances, or volumes. Internal responses provide additional context for judging whether those programs create comparable physiological stress. Such comparisons support research in exercise physiology and sports science, where investigators examine relationships among workload, biological adaptation, recovery, and performance.
In rehabilitation, workload information can help relate an activity program to the organism’s physiological response and recovery needs. In disease-prevention research, the same framework helps investigators study how workload balance may influence health. These applications also support individualized programs by connecting measured exercise demands with biological responses rather than relying only on activity volume.
