196 Training for Specific Environments
Acclimation to Altitude
Prolonged exposure to altitude will bring about several physiologic changes and
result in improved exercise tolerance at submaximal effort levels. At levels above 10,000
feet (3,050 meters), maximal aerobic capacity is limited and is lower than what would be
measured at sea level. Below 10,000 feet, maximal aerobic capacity may approach sea level
values, but usually only after a 2 week acclimation period. Because of this inability to
achieve maximal aerobic capacity above 10,000 feet, elite endurance athletes may
experience mild to moderate aerobic deconditioning with extended stays at altitude.Training in Confined Spaces
During deployments or extended training exercises it is not uncommon to be
confronted with conditions which may limit physical training routines. Complete cessation
of physical training will result in a significant and rapid reduction in both strength and
endurance capacity (see section on Deconditioning). Submarines and small assault craft
probably create the greatest challenge, but under almost all circumstances where time is not
a limiting factor a reasonably well balanced training program can be maintained with a
minimal amount of equipment. The following is a list of both aerobic and anaerobic
training modalities for confined spaces:" Calisthenics.
" Pull-ups and dips.
" Grip balls for grip strength.
" Resistance equipment such as the Exergenie which imitate swimming strokes
and are very light weight." Therabands, another lightweight resistance tool to maintain strength in major
muscle groups." Jump rope.
" Stair stepping (monotonous but good aerobic workout without need of special
equipment)." Plyoball.
" Free weights.
" Running in place.
