Abstract:

The objectives of this study were to 1 determine the distribution of injuries occurring during loaded treadmill marching, 2 determine if there are significant anthropometric changes that occur in the foot during this marching, and 3 identify variables speed, load that may affect these injuries and foot changes. This study documented a large number of minor injuries N equals 82 among physically fit soldiers marching on a treadmill at fast speeds and over a long distance with heavy loads. Significant pre to post foot anthropometric changes P less than .05 were observed in ball of foot and instep circumferences with a tendency for these changes to occur with the heavier loads while ankle circumference changes occurred throughout most of the conditions. The results of this study indicate that 1 load carriage injuries occurring during a prolonged treadmill march primarily involve the lower extremities and back, 2 foot blisters were the most common injury recorded, 3 the standard Army practice of using foot powder and undergoing frequent sock changes does not prevent blister formation during prolonged treadmill marches, 4 the most common types of back injury was upper back straining.
