Cormack et al. observed altered flight time to contraction time ratio up to 2 days after elite competition โdespite little changes in jump height performanceโ Different movement solutions occur to maintain a desired โperformanceโ metric such as jump height or power output Legg et al. suggested that altering CMJ mechanics assisted with maintenance of jump height while in a fatigued state, with changes in dip magnitude observed midseason despite no change in jump height. 2๏ธโฃRSI-mod as an alternative variable ?? CMJ height alone may not always discriminate between rugby league cohorts, emphasizing the requirement for the associated underpinning force-time variables [to indicate jump โstrategyโ], or RSImod at the very least McMahon et al. reported that a group of combined professional senior SL and RLC rugby league players who performed the CMJ with a โhigher RSImodโ demonstrated higher force, velocity and thus power outputs. 3๏ธโฃSensitive to change of different metrics , Jump Height ๐ RSI-mod? CMJ height was not sensitive to change in neuromuscular status of elite Australian Rules Football athletes pre- to post-match, from 48-hours pre- to 48-hours post-match ๐Conclusions - RSImod or FT:CT may prove more useful overall as an indicator of readiness, slow SSC activity, and neuromuscular fatigue as they impact the coordinative strategy and jumping performance. - A decline of 8% in FT:CT or RSImod would indicate a change requiring intervention as at this level of neuromuscular fatigue there are considerable changes to performance ๐ ๐Hughes, S., Warmenhoven, J., Haff, G.
