Abstract
The study evaluated the capacity of military personnel to perform maximal exercise before and after 5 days of sustained physical activity. An additional goal was to evaluate whether a carbohydrate supplement to the regular field rations would reduce the extent of any performance impairments. Subjects (Ss) were 29 male volunteers from the Canadian Forces Airborne Regiment. They were allowed 4-5 h sleep each 24 h and 45 min per meal, but were otherwise continuously occupied with physical demanding missions in a field environment. The results demostrated that the Ss were in a marked negative caloric balance by the end of the field trial. Skeletal muscle glycogen stores were markedly depleted. In association with these changes there were significant impairments at the end of the trial in maximal aerobic power, maximal dynamic strength, and anaerobic power of large muscle groups. TRUNCATED
