Frequency domain parameters of HRV in control and overweight groups

S. No	Parameter	Control group (n=40)	Overweight group (n=40)	p-value
1	LFnu	47.2 ± 12.54	68.18 ± 11.16	<0.001
2	HFnu	52.8 ± 12.54	31.82 ± 11.16	<0.001
3	LF:HF	0.895 ± 225.56	2.71 ± 1.80	<0.001
4	TP (ms2)	932.67 ± 435.45	596.50 ± 276.63	<0.001

Values are expressed as mean±SD; TP: Total power, LF: Low frequency component, HF: High frequency component, LFnu: Normalized low frequency component, HFnu: Normalized high frequency component
