Time courses and area under curves of postlunch heart rate variability (HRV) indices. Heart rate (A, HR, in bpm), low-frequency (B, LF, in ms2), high-frequency (HF) in ms2 (C) and in normalised units (D, HFnu), and LF/HF ratio (E). The black rectangles indicate lunch intake period and the grey rectangles indicate the 15 min gas exchange periods. All results are mean ± SEM. *EX significantly different from RT, p < 0.05.
