The purpose of this study was to compare world class (A) vs 15-16m (B) and 13-14m (C) classes of Japan, regarding distances, ratio of distances, contact time and flight time in the triple jump. The method of study was to measure and analyze distances, ratio of distances, contact time and flight time. The data of Group A (World class) was quoted from measurements at The Second World Championships (by P. Susanka, and other officials, see Table 2). The method of measuring data in Group B (15-16m class) and C (13-14m class) was measured from a Videocamera (Contact time and Flight time) and actual survey (Distance) in competition at Tokai University in Japan (Tables 3,4). 1) Distance of hop, step and jump. Group A was predominant over Group B and C in distances of hop, step and jump. A difference was noted in the distance of step. (Fig. 1) There was a correlation between record and distance of jump in Group A and C. There were also correlations in the hop and step of Group B (Table 5). 2) The ratio of hop, step and jump. In Group A was hop=35.4%, step=30.8%, jump=33.8%. This was in agreement with a number of current reports in world class. Group B differed from group A in hop and step (Fig.2) 3) Contact time. Hop was the smallest, followed by step, and jump was the largest in all Groups. There was no difference in any Group (Fig. 3). There was no correlation between contact time and distance (Table 6). 4) Flight time. Jump was the biggest, followed by hop, and step was the smallest in all Groups. There was no difference among hop and step of Group A. There was a difference between Group B and C (Table 8,Fig.4). The correlation between flight time and distance, there was a correlation in hop and step of Group A. There was a correlation in step and jump of Group B, and in hop, step and jump of Group C. There was a difference in hop between Groups A and B (Table 7). The results of this study show a difference in hop and step among 15-16m class and World classtriple jumpers.
