Percentage Change from Pre-injury Baseline of Heart Rate, Mean Arterial Pressure (MAP), and Body Temperature (Mean ± SEM)

		Heart rate (bpm)		Δ Temperature (°C)		Δ MAP (mm Hg)
Group	n	0–1 h post	1–6 h post	0–1 h post	1–6 h post	0–1 h post	1–6 h post
Sham	2–3	−19.2 ± 6.7	−11.1 ± 9.1	−2.4 ± 1.3	−0.7 ± 2.2	39.5 ± 1.7
4-week-old low	4	−10.3 ± 5.0	16.1 ± 14.5	−0.9 ± 0.5	2.9 ± 0.6a	15.2 ± 12.9	14.4 ± 7.4

No significant differences were noted between any groups, but temperature was significantly increased at 1−6 h post-injury compared to 0-1 h post-injury in 4-week-old low- and moderate-acceleration groups. Heart rate was significantly increased at 1−6 h post-injury compared to 0−1 h post-injury in the 4-week-old moderate-acceleration groups.

^aSignificantly different from 0−1 h post-injury; p < 0.05.

SEM, standard error of the mean; bpm, beats per minute.
