Measuring physical fitness and cardiovascular efficiency using harvard step test approach under fuzzy environment

One may not be able to measure exactly the various parameters involved in computing physical fitness and cardiovascular efficiency of a human being. Inexactness, in turn, may lead to inaccurate results and misleading conclusions. In the present paper, using fuzzy arithmetic, we modify both the Long Form and in Short Form approach associated with the Harvard Step Test, under fuzzy environment. The advantage of fuzzy arithmetic is that it takes into consideration the vagueness (inaccuracy or imprecision) involved in the process of Harvard Step Test whereas the crisp arithmetic approach used by other researchers ignores this aspect.
