Table 3.

Intramyocellular acetylcarnitine (AcCtn) concentrations (mmol/kg) at baseline, after 2 hours of exercise, and 24 hours post-exercise.

	all study participants (n = 14)	GHD (n = 7)	CS (n = 7)
Baseline	0.35 ( ± 0.48)	0.33 ( ± 0.50)	0.38 ( ± 0.51)
2 hours	1.66 ( ± 1.47)	1.30 ( ± 1.19)	2.01 ( ± 1.72)
24 hours	0.75 ( ± 0.78)	0.63 ( ± 0.43)	0.88 ( ± 1.05)
p-value (time course) (ANOVA)	p = 0.0023	p = 0.067	p = 0.045
p-value for group effect (ANOVA)	P = 0.45 No significant interaction between group and time

GHD = patients with growth hormone deficiency; CS = control subjects.

Values are mean ( ± SD). Differences between time-points were tested after repeated measures ANOVA by Sidak’s multiple comparison test versus baseline.

AcCtn concentrations at baseline (unpaired t-test, p = 0.90), as well as changes over time (ANOVA) were similar between GHD and CS.
