Figure 10-1. Workload and Energy ExpenditureDuring Load-Bearing77 LBS AT 2.1 MPH56 LBS AT 2.1 MPH40 LBS AT 3 MPH OR 80 LBS AT 1.5 MPH OR 120 LBS AT 1.2 MPHHoursCarrying a load at a walking pace that requires an energy expenditure in excess of300 kcal per hour can compromise the energy reserves you will need at the desireddestination. Figure 10-2 shows the speeds that you can expect to sustain with given loadsat the designated paces: note these all result in an energy expenditure of 300 kcal per hour.Figure 10-2.

Hydration StatusAppropriate water/fluid discipline must be observed at all times during loadbearing.Exercise without a load is severely compromised when dehydration occurs, andwhen exercise is coupled to load-bearing, dehydration potentially becomes an evengreater threat. This is true regardless of the environmental conditions. The Navy SEALNutrition Guide provides information on optimal fluid ingestion, but in brief, you shouldingest at least one to two cups of fluid every 30 minutes during a hump.Fluid requirements are higher duringexercise with load-bearing than duringexercise without load-bearing.Environmental Stress" Hot and dry or hot and humid environments will increase the heat strainof individuals during load-bearing. Thermal heat load will be increased due tobody heat production from load-bearing activities, and from the heat loadfrom the sun and other heat sources in the environment. ALICE packs anddouble packs can restrict the body’s ability to dissipate heat. Load-bearingvests with a nylon mesh body will trap less heat than backpack designs." Cold environments increase the energy cost of walking because the clothingworn is usually heavy and cumbersome. This can result in overheating andsweating, especially on the back where the load is carried. Hypothermia(drop in body temperature below 95˚C) can also occur rapidly in cold environmentsif the inner layers of clothing are wet when you stop exercising." Moderate to high altitudes decrease exercise capacity since the availableoxygen in blood decreases as altitude increases due to lower barometric pressure." Sandy terrain significantly increases energy expenditure up to 80% orgreater as compared to walking on a firm surface. The energy demandincreases with the difficulty of the terrain.Sleep LossThe Navy SEAL Physical Fitness Guide 179
