Abstract

The purpose of this study was to examine the effects of bath load and task duration on stride length, stride period, velocity (calculated in m/s and statures/second), cadence, elbow angle, arm angle and hip angle of the human body during a manual materials handling task on an inclined surface. Eight male subjects (mean age 22.58 $\pm$ 2.42 years) were used as subjects in this study. Each subject was required to repeatedly ascend and descend a 7.47 m runway inclined to a 9.41$\sp\circ$ slope, carrying a load on each ascent, for a period of fifteen minutes. Ascents began at thirty second intervals. The three load conditions used in this study were 6.25 kg, 11.25 kg and 18.25 kg. The subjects' stride lengths and stride periods decreased significantly when ascending a 9.41$\sp\circ$ inclined surface with the 18.25 kg load. The subjects' cadence increased significantly when ascending the inclined surface with the 18.25 kg load. The elbow angles of the subjects significantly increased as they ascended the inclined surface with the 18.25 kg load. The elbow angles of the subjects were also significantly different when measured at 0, 50 and 100 percent of the subjects' stride length. The arm angles of the subjects significantly decreased as they ascended the inclined surface with the 18.25 kg load. The arm angles of the subjects were also significantly different when measured at 0, 50 and 100 percent of the subjects' stride length. The results of this study suggest that changes in stride length, stride period, cadence, elbow angle, arm angle and hip angle occurred when completing a manual materials handling task on a 9.41$\sp\circ$ inclined surface. The results indicate that these changes are dependent on the mass of the load being handled. Based on the results of this study in the completions of the required task, which was 15 minutes in duration, time does not affect any of the reported gait characteristics or body positions.Dept. of Kinesiology.
