520    The purpose of this study was to compare the time required
       to sprint a distance of 20 meters using both traditional 
       starting blocks and the Moye starting system. Twenty-four 
       male track and field athletes from the United States Air 
       Force Academy, the University of Colorado, and the 
       University of Northern Colorado served as subjects for the
       study 
520    Each subject was randomly assigned to use either the Moye 
       starting system or traditional starting blocks first. Four
       trials were performed from each block. The best 
       performance for each block type was selected for each 
       subject. Each trial was measured by an automatic timing 
       system which was activated when the sprinter's hand moved 
       from the touchpad and stopped when the athlete broke the 
       beam of the photo-electric cell located 20 meters from the
       starting line. Ten meter performance times were generated 
       from film analysis 
520    At a distance of 10 meters, 15 (62.50%) of the subjects 
       recorded faster performances using the Moye system while 
       one (4.17%) subject recorded a faster time using the 
       traditional starting blocks. Eight (33.33%) subjects saw 
       no change. At a distance of 20 meters, 17 (70.83%) of the 
       subjects recorded faster performances with the Moye system
       while six (25.00%) subjects recorded faster times using 
       the traditional starting block. One (4.17%) subject 
       recorded identical performances 
520    Using analysis of variance (ANOVA), it was concluded that 
       starting block type had no effect on either 10 or 20 meter
       performance time and that no difference in corresponding 
       velocity values existed for athletes using the Moye 
       system. It was also concluded that using the Moye system 
       resulted in a longer initial stride and that those 
       athletes whose primary event group was sprints and/or 
       hurdles produced better 10 and 20 meter performance times 
520    Three subjects that showed improvement, no change and 
       decreased results with the Moye system were selected and 
       digitized to compare the mechanical differences with each 
       block. It was determined that a higher and more consistent
       center of gravity path resulted when using the Moye system
       allowing the athlete to become upright sooner
