Sustained combat operations degrade soldier performance by reducing anabolic hormones, muscle mass, and bone density. Understanding these physiological changes helps commanders plan missions and implement countermeasures to maintain warfighter effectiveness.
Area of Science:
- Military medicine
- Exercise physiology
- Occupational health
Background:
- Combat missions impose significant operational stressors on soldiers.
- Sustained operations can lead to a decline in physical and military performance.
- Physiological consequences include reduced anabolic hormones, skeletal muscle mass, and bone mineral density.
Purpose of the Study:
- To review current literature on physical and physiological decrements in soldiers during sustained operations.
- To provide commanders with information to enhance or sustain warfighter performance.
- To inform mission planning with potential countermeasures.
Main Methods:
- Literature review of scientific studies.
- Analysis of physiological impacts of combat stress.
- Examination of performance decrements.
Main Results:
- Sustained operational stress is linked to decreased anabolic hormones.
- Loss of skeletal muscle mass is a common outcome.
- Reduced bone mineral density affects soldier health and performance.
Conclusions:
- Commanders need to be aware of the physical and physiological toll of sustained operations.
- Implementing countermeasures can mitigate performance decline.
- Informed planning is crucial for maintaining warfighter readiness and effectiveness.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Hypothalamic-Pituitary Axis
