In this report we demonstrate techniques that can be used to investigate the biology of the crayfish hindgut. We show how to dissect a crayfish abdomen and study the associated anatomy, physiology and modulation of activity. The peristaltic activity and strength of contractions are measured using a force transducer.

Autophagy activation is beneficial in the prevention of a number of diseases. One of the physiological approaches to induce autophagy in vivo is physical exercise. Here we show how to activate autophagy by aerobic exercise and measure autophagy levels in mice.
FAQs
During a bout of activity, oxygen delivery rises alongside cardiac output, while ventilation and energy metabolism adjust to support contracting muscle. Thermoregulation also changes to help manage the increased demands. These linked responses explain why heart rate, oxygen consumption, blood pressure, and fatigue are measured together rather than interpreted as isolated findings.
Repeated training can alter functional capacity and the way the body responds to a given workload. Long-term adaptation is therefore evaluated against responses to physical activity, including oxygen consumption, heart rate, fatigue, and recovery. In clinical exercise physiology, this comparison helps determine whether an intervention is improving function rather than merely documenting a single session.
The pattern among measured variables can indicate where exercise capacity is limited. Oxygen consumption reflects the body's demand during activity, while cardiac output and ventilation describe major parts of oxygen delivery and respiratory response. Blood pressure and fatigue add information about circulatory response and tolerance. Considering them together supports interpretation of performance and recovery.
Cardiopulmonary exercise testing brings several exercise-related responses together for clinical assessment. Measurements such as oxygen consumption, heart rate, blood pressure, ventilation, and fatigue can reveal how the cardiopulmonary system responds as demands increase. The resulting pattern helps identify functional limitations and provides a basis for monitoring recovery or tailoring rehabilitation.
Exercise physiology informs individualized prescription by linking observed responses with a person's clinical condition and functional capacity. Rather than applying one workload to everyone, clinicians can use measured heart rate, oxygen consumption, blood pressure, and fatigue to guide safer, more effective interventions. This approach is relevant across cardiovascular, pulmonary, metabolic, and musculoskeletal conditions.
In clinical rehabilitation, repeated assessment shows whether a person is tolerating activity and recovering as expected. Exercise-related measurements can document functional limitations, track changes during an intervention, and help refine subsequent exercise prescription. The same framework applies to cardiovascular, pulmonary, metabolic, and musculoskeletal conditions, making exercise physiology useful for individualized monitoring and safer care.
