The relation between habitual exercise and the basal metabolic rate, energy expenditure during exercise (lactic threshold and maximal oxygen uptake) was examined in 291 older people. Metabolic rate was highest in old players of gatebowl (a form of croquet) (male; 23.3±2.3, female; 22.7±3.0kcal/kg/day), higher in old untrained people (male; 21.9±2.5, female; 20.8±2.4kcal/kg/day), and lower in old people in a home for the aged (male; 20.6±3.5, female; 20.8±3.7kcal/kg/day). Energy expenditure while walking at a speed of less than 100m/min was similar in trained and untrained old people aged 60-69 years. However, lactic threshold was higher in trained (30.2±4.8ml/kg/min) than in untrained (20.9±2.8ml/kg/min) females aged 60-69 years. Maximal oxygen uptake was higher in trained (male; 50.4±4.1, female; 36.6±3.9) than in untrained (male; 30.9±3.7, female; 26.8±2.8) old people aged 60-69 years. It was suggested that a higher basal metabolic rate, lactic threshold and maximal oxygen uptake resulted in higher daily physical activity and larger daily energy consumption in trained old people.
