This study analyzed the amount of efforts on the approach run produced by 9 triple jumpers during a trial meet. It also analyzed their full sprints performed on the same runway as the approach run following the trial meet. In the trial with the best record, a significant correlation (r=0.679, p<0.05) was observed between the approach run speed and the record of triple jump. The approach run speed was higher in the trial with the best record than the one with the worst record except for one jumper. The running speed was significantly lower in the middle and the last 5 steps of the approach run than in full-effort running (p<0.05), and the pitch was significantly lower in the first 5 steps and the middle of the approach run than in full-effort running (p<0.001). The mean amount of effort was 78% in the first half and 85% in the second half of the approach run, and the jumpers clearly reserved power throughout the approach run. During the approach run, the running speed was 93.7-96.0% in the first half and 96.0-96.5% in the second half, the stride was 112.3-106.8% and 106.8-96.0%, and the pitch was 83.3-87.6% and 87.6-98.8%, respectively, compared with full-effort running. These results suggest that the approach run speed is an important determinant of the record of the triple jump. It was also found that triple jumpers ran-up at 80-90% of their maximum effort. The percentage of the approach run speed relative to the full-effort running speed was considerably higher than the amount of effort, which was associated more closely with the pitch.
