Table 3. Mean (SD) variable outcomes of sound and temporal kinetic measures during precision landings performed from two heights relative to standing height (25% and 50%) for traceurs and recreationally trained participants.
Traceurs Recreational
25% 50% 25% 50%
Maximal sound (dB) 64.2 (3.3) 64.1 (2.7) †  66.6 (4.1) 70.4 (7.9)
mVF (BW) 2.5 (0.2)* 3.6 (0.4) †  4.4 (1.8) 7.4 (2.9)
Time to mVF (ms) 91(16)* 56(14) †  57(22) 35(10)
Loading rate (BW/s) 29.9 (7.0)* 83.3 (62.3) †  99.2 (69.6) 247.8 (142.3)
dB = decibels, mVF = maximal vertical force, BW = bodyweight, ms = milliseconds,* = significant difference (p<.05) between groups for 25% height,†  = significant difference (p< .05) between groups for 50% height.
