AB  - Purpose: This study assessed the utility of force-time characteristics from the 
      isometric midthigh pull (IMTP) as a measure of neuromuscular function after 
      elite-level Australian rules football matches. It was hypothesized that rate 
      characteristics of force development would demonstrate a different response 
      magnitude and recovery time course than peak force measurements. Methods: 
      Force-time characteristics of the IMTP (peak force, 0- to 50-ms rate of force 
      development [RFD], 100- to 200-ms RFD) were collected at 48 (G+2), 72 (G+3), and 
      96 h (G+4) after 3 competitive Australian rules football matches. Results: 
      Meaningful reductions (>75% of the smallest worthwhile change) were observed at 
      G+2, G+3, and G+4 for RFD 0-50 milliseconds (-25.8%, -17.5%, and -16.9%) and at 
      G+2 and G+3 for RFD 100-200 milliseconds (-15.7% and -11.7%). No meaningful 
      reductions were observed for peak force at any time point (G+2 -4.0%, G+3 -3.9%, 
      G+4 -2.7%). Higher week-to-week variation was observed for RFD 0-50 milliseconds 
      (G+2 17.1%, G+3 27.2%, G+4 19.3%) vs both RFD 100-200 milliseconds (G+2 11.3%, 
      G+3 11.5%, G+4 7.2%) and peak force (G+2 4.8%, G+3 4.4%, G+4 8.4%). Conclusions: 
      These findings highlight the potential use of rate characteristics from the IMTP 
      as measures of neuromuscular function in elite sport settings, and in particular 
      RFD 100-200 milliseconds due to its higher reliability. Interestingly, peak force 
      collected from the IMTP was not meaningfully suppressed at any time point after 
      elite Australian rules football match play. This suggests that rate 
      characteristics from IMTP may provide more sensitive and valuable insight 
      regarding neuromuscular function recovery kinetics than peak measures.
