Triple jump phases: competitive progress specific pace and rhythm analysis
(Die Rhythmusdynamik im Dreisprung in Relation zum Leistungsniveau der Springer)
Objective of the study was to analyze the competitive progress specific triple jump control rhythm and aerial/ ground phase ratios for the men`s triple jump elite.
Methods and structure of the study. We used for the purposes of the study photodiode video capturing Brower system with the triple jump replay analysis (using Dartfish software), with the tests and analyses assisted by marks in the triple jump sector. Subject to the analysis were the spatial and temporal rates of the aerial and ground phases in the triple jump sequence. 52 elite triple jump competitors qualified Class I to WCMS were sampled for the study to fix and analyze their individual best triple jump attempts to produce the temporal and spatial control rates. A total of 160 triple jump attempts were analyzed during the Russian and international competition.
Results and conclusions. The study found the hop and jump phase ratios (%) in the men`s elite triple jump sequence coming closer with the competitive progress, with the hop phase sagging and the jump phase growing. The aerial/ ground phase ratios for the triple jump leaders including the four-time world champion K. Taylor (18.21 m) and world record holder D. Edwards (18.29 m) were found close to 35+30+35%. Therefore, we recommend a model triple jump phase ratio for the triple jump elite (WCMS) with the hop, step and jump phases close to 35+30+35%. It should be emphasized that with the competitive progress the men`s triple jump elite demonstrate the hop and jump phase ratios coming closer to ideally model the D. Edwards` (18,29 m) standard of 30+30+40%. With the 15.1% competitive progress (from 15.48 to 17.82 m), the triple jump time was found to grow insignificantly by 3.4% only - that may be interpreted as indicative of the competitive progress in the triple jump depending rather on the sprint speed and aerial/ ground phase speeds in every triple jump element, i.e. the individual ability to keep the top horizontal speed in every triple jump phase. Note that the competitive progress with speed correlation ratio for the last approach segment was estimated to average 0.93 in our study.
