TI  - Energy expenditure from minute-by-minute heart-rate recording: comparison with 
      indirect calorimetry.
PG  - 552-9
AB  - Total daily energy expenditure (TDEE) and energy expended in activity (EAC) were 
      estimated by the minute-by-minute heart-rate method in 22 (16 men, 6 women) 
      individually calibrated subjects and compared with values obtained by whole-body 
      indirect calorimetry. Subjects followed four activity protocols during the 22 h 
      in the calorimeter; no exercise (n = 6) and 2 (n = 5), 4 (n = 4), and 6 (n = 6) 
      30-min bouts of exercise on a bicycle ergometer at varying intensities. There 
      were no statistically significant differences between the two methods in TDEE or 
      EAC in any of the sex or protocol groupings. The regression of TDEE by heart rate 
      on TDEE in the calorimeter was y = 0.92x + 1.0 MJ; (r = 0.87, SEE = 0.91 MJ). The 
      heart-rate method also follows the varying activity patterns of individuals and 
      can be used to closely estimate the TDEE and EAC of even small (n = 4-6) groups 
      of subjects. In the present measurements, it gave a maximum error of TDEE for 
      individuals of +20% and -15%.
