Environmental Considerations

Soldiers must be ready to perform physically demanding tasks in hot, cold, and high altitude environments. Acclimatization to these environments during the conduct of PRT and other daily training activities is essential to safely preparing Soldiers for physical success. When gradually exposed to these environments and the intensity and duration of activities are adjusted, Soldiers …

Cold Acclimatization

COLD ACCLIMATIZATION During exercise in the cold, the body usually produces enough heat to maintain its normal temperature. As Soldiers become fatigued, however, they slow down and their body produces less heat. Two types of cold injury conditions may occur due to prolonged exposure and/or loss of core temperature. Soldiers and PRT leaders must be …

Cold Injuries | PT Weather Chart & Uniform Regulations

The Army Physical Training (PT) weather chart provides guidelines on conducting outdoor physical training in various weather conditions to ensure the safety and well-being of soldiers.  Typically, this kind of weather chart categorizes conditions into different flags or colors, each representing a level of risk.  Army Weather Chart for Physical Activity Some general guidelines from …

Heat Acclimatization

HEAT ACCLIMATIZATION Soldiers need to acclimatize properly prior to conducting PRT in extremely hot environments. Heat acclimatization allows for those specific adaptations that aid in the reduction of physiological stress (heart rate, core temperature, and sweat adaptation). It also improves physical work capability in the heat and builds Soldier confidence. In hot environments Soldiers will …

Altitude Acclimatization

ALTITUDE ACCLIMATIZATION Soldiers may be deployed to theaters of operation that are at altitudes in excess of 3000 feet above sea level. Altitude acclimatization allows Soldiers to decrease their susceptibility to altitude illness and achieve optimal physical and cognitive performance for the altitude to which they are acclimatized. Altitude acclimatization has no negative side effects …

Hydration and Nutrition

HYDRATION AND NUTRITION Ensuring that Soldiers are properly hydrated and receive regular, adequate nutrition is a good way to prevent the onset of heat injuries. Water is the preferred hydration fluid before, during, and after physical training activities. Drink 13 to 20 ounces of cool water at least 30 minutes before beginning exercise (approximately 2 …
