Abstract
Previous work by Mital et al. showed that repetitive dynamic strength (RDS) of individuals
is a better predictor of psychophysically acceptable weight (PAW) than either the
maximal dynamic strength (MDS) or maximal static strengths (MSSs). It was also pointed
out that somewhere between a frequency of one lift per minute and a frequency of three
lifts per minute, the orientation of lifting tasks changes and muscular strengths
no longer remain the limiting factor. This paper reports the results of a follow-up
study conducted to pinpoint the lifting frequency just beyond which this transition
takes place. The results indicated that a significant correlation existed between
RDS and PAW for lifting frequencies up to 1·5 lifts per minute. Beyond 1·5 lifts per
minute, no significant correlation between the two measures was found. We therefore
concluded that lifting tasks performed every 40 seconds, or less frequently, are strength
oriented. For those tasks which require lifting more frequently than once every 40
seconds, individual's strengths are not a limiting factor.
