Abstract (300 words maximum)
To compare mid-thigh pull force-time characteristics, seven elite (EA; 27.1 ± 4.4 years; 169.6 ± 12.3 cm; 81.6 ± 13.2 kg) and eight recreational (RA; 33.0 ± 8.2 years; 171.8 ± 13.5 cm; 76.3 ± 19.5 kg) HIFT athletes volunteered for this study. Following a standard warm-up, athletes completed three maximal-effort mid-thigh pull (IMTP) assessments while standing on a portable force plate. Peak force (PF), peak RFD from the highest IMPT effort (RFDPeak), average RFD (RFDAVG), and RFD at specific time bands from 0 to 30, 50, 90, 100, 150, 200, and 250 milliseconds were recorded for analyses. Separate independent samples t-Tests revealed no differences (p > 0.05) in PF (EA: 1871 ± 503 N; RA: 1636 ± 449 N), RFDPeak (EA: 1295 ± 709 N; RA: 810 ± 421 N), average RFD (EA: 1346 ± 1553 N; RA: 575 ± 421 N), and RFD30 (EA: 11800 ± 10915 N; RA: 7680 ± 7624 N), RFD50 (EA: 9839 ± 7733 N; RA: 6522 ± 6223 N), RFD90 (EA: 7867 ± 4658 N; RA: 5465 ± 4246 N), RFD100 (EA: 7618 ± 4069 N; RA: 5285 ± 3814 N), RFD150 (EA: 7183 ± 2961 N; RA: 4974 ± 2785 N), RFD200 (EA: 6643 ± 2524 N; RA: 4837 ± 2523 N), and RFD250 (EA: 5787 ± 2028 N; RA: 4460 ± 2109 N). Force production and RFD may be relevant to HIFT, but IMTP force-time characteristics do not appear to distinguish between elite and recreational-level athletes.
