Physical conditioning guidelines for students Published June 1, 2011 81st Medical Group KEESLER AFB, Miss. -- Physical training for Air Force members at Air Education and Training Command installations is outlined in AETC Instruction 48-101, Prevention of Heat Stress Disorders. To avoid the heat, physical training should be conducted during the most weather-favorable time of the day. Under AETC Instruction 36-2216, Administration of Military Standards and Discipline Training, Keesler won't accomplish physical training for nonprior service Airmen under black flag conditions. Military training leaders refer to AETCI 48-101, Table 1, to define work/rest cycles for remaining flag conditions. MTLs reference AETCI 48-101, Figure 1, for heat stress and water intoxication warning signs and symptoms to ensure all nonprior service Airmen accomplish the mission safely. At Keesler, nonprior service Airmen accomplish a 20-minute self-paced run on Mondays, Tuesdays and Thursdays and a timed 1 1/2-mile run once a month, according to Master Sgt. Anthony Fisher, superintendent of military training for the 81st Training Group. Physical training begins at 4:00 a.m. or 9 a.m., depending on class schedules. Workouts also include warm-up and cool-down periods. Wednesdays, other military training activities such as open ranks inspections are conducted.
