Maintenance of aerobic capacity and body composition of volunteers residing on a metabolic research unit.
To achieve steady-state energy equilibrium, a program of physiological assessment and aerobic exercise prescription was developed and evaluated in healthy men participating in 3 month (n = 21) and 6 month (n = 12) nutritional studies. Using reliable maximal exercise tests, exercise was prescribed at an intensity to elicit 50% peak oxygen uptake, 15 minutes/day on 3 nonconsecutive days/week. Under controlled controlled conditions of energy intake and exercise prescription, body weight (+/- 2%), body composition, and peak oxygen uptake (+/- less than 5%) were maintained for periods up to 6 months. This approach may be useful in regulating energy expenditure in volunteers participating in controlled metabolic studies for prolonged periods of time.
