FIGURE 1— Population distributions of (a) daily total energy expenditure (1 kJ/d = 4.2 kcal/d) for 30 minutes of daily moderate walking, (b) gains in energy expenditure for 30 minutes of daily moderate walking, (c) daily total energy expenditure for 30 minutes of daily brisk walking, and (d) gains in energy expenditure for 30 minutes of daily brisk walking by 6010 randomly selected adult (3014 men, 2996 women, aged 35–74 y) residents of Geneva, Switzerland, 1997–2001.
Note. EE = energy expenditure. Increases to recommended frequency, duration, and intensity of walking were assumed to be possible only for persons walking less than the recommendation (eligible adults), and prevalent compliers were assumed to continue their walking habits without change. Gains are for moderate walking (3.9 basal metabolic rate) for 30 minutes per day by prevalent compliers and 50% of eligible adults and for brisk walking (4.7 basal metabolic rate) for 30 minutes per day by prevalent compliers and 50% of eligible adults.
