Values are means ± SE. HF, high frequency; HRV, heart rate variability; LF, low frequency; nu, normalized units (represent the relative value of each power component); N, normal; NH, offspring from lean (N) parents that were fed high-fat (H) diet after weaning; NN, offspring from lean normal (N) diet-fed parents that were also fed an N diet after weaning.
