Performance Outcomes of Cross-Country Running Structured in a Voluntary Activity Class

Abstract

Running performance and metabolic variables were evaluated in 28 college males during the period of a 10-wk cross-country activity class. The basic criterion measure was the 3-mi run time while treadmill tests were used to determine oxygen uptake at the speed of the field test as well as under maximal conditions. Increased running performance was not attributed to changes in maximum oxygen consumption but to a greater use of aerobic capacity. The results of the study support improved physiological efficiency during submaximal and maximal activity as an outcome of the training program. It was generally concluded, however, that training load within the constraints of a voluntary cross-country activity course may frequently be too limited to justify physical fitness as a course objective.
