Abstract

The purpose of this study was to compare the effect of natural and refined sugar at an instantaneous, pre-absorptive level on quadriceps peak torque and to measure any prolonged effect on normal, healthy subjects. The experimental group (n=40) was randomly assigned to sugar testing order, with refined sugar testing occurring on one day and natural sugar testing occurring on the opposite day. The control group (n=10) followed the same protocol but held distilled water in their mouth. Isokinetic peak torque was recorded for each subject at three intervals, pretest, post-test I (~1 min.), and posttest n (-15 min.). Results showed that neither the sugars nor the placebo had a significant effect on peak torque in under one minute. However, both sugars produced a significant decrease (p<0.05) in peak torque at the fifteen-minute interval, while the placebo did not. The authors concluded that both natural and refined sugar had a negative effect on peak torque approximately fifteen minutes after its administration.
