The effects of fatigue on movement patterns, recorded by color-coded multiple-image photography, were investigated. In the main experiment, the movement patterns of 13 subjects were photographed before, during, and after fatigue inducing procedures. Patterns were obtained for the movements of broad jumping, sitting-to-standing, and standing-to-sitting. Linear and angular measures taken from pre- and post-fatigue patterns were compared. Correlations of selected broad jump measures with jump length decrement were computed. Statistically significant changes in pattern measures were found for all three movements. Some but not all pattern changes correlated highly with jump length decrement. Author
