ABSTRACT
BACKGROUND: The aim was to evaluate the working capacity and resting energy expenditure in patients who had undergone restorative proctocolectomy. METHODS: Of 72 patients operated on between April 1990 to September 1998, 51 were eligible and 38 participated in the study. Resting energy was assessed by indirect calorimetry, and working capacity by ergospirometry on an exercise bicycle. RESULTS: The median functional score was 2 (range 0-7). Oxygen uptake during rest was reduced for men compared with predicted values. The corresponding values for women were in keeping with predicted values. The median working capacity was 96 (range 59-102) per cent for women and 91 (range 51-113) per cent for men, compared with reference values of maximum workload based on age, height and sex. There was no correlation between functional score and any other variable measured. CONCLUSION: Patients who have undergone restorative proctocolectomy for ulcerative colitis have normal resting energy expenditure and working capacity.

OBJECTIVE: To find out whether weight reduction induced by vertical banded gastroplasty (VBG) alters the energy expenditure in severely obese women during treadmill walking. DESIGN: A prospective one year follow-up study, patients being their own controls. SETTING: University hospital, Sweden. SUBJECTS: A consecutive series of 11 women who had VBG. MAIN OUTCOME MEASURES: Indirect calorimetry, body mass index (BMI), preset and comfortable walking speeds, heart rate, perceived exertion, and quality of life. RESULTS: 11 patients were evaluated. Mean BMI (kg/ml) decreased from 41 (range 36-46) before to 32 (range 25-37) 12 months postoperatively. The energy expenditure decreased significantly both at comfortable and preset walking speeds. The comfortable walking speed increased from 2.7 km x h(-1) (range 1.3-3.4) before operation to 3.8 (range 2.0-4.2) one year postoperatively (p = 0.003). All bodily variables in the SF-36 questionnaire showed improvement from 6 months onwards. CONCLUSION: Weight reduction in women reduces the energy expenditure during walking both at comfortable and preset speeds. The comfortable walking speed is increased. The improvements are reflected in the patients' own assessment.

Walking is a complex process and the physiotherapist must focus on physical signs as well as functional and practical tests to evaluate treatment. Measurement of energy expenditure during level walking is a useful objective parameter for assessing walking as being a valuable supplement to evaluate the outcome of physiotherapy. This study had two purposes. The first purpose was to investigate whether sampling and measurement of oxygen consumption were reproducible when using two different devices during walking on a treadmill. A second purpose was to find out whether the measurements were sensitive enough to reveal differences in energy expenditure and respiratory quotient (RO) during different walking speeds. Ten healthy students (mean age 22 years; range 20-25 years) volunteered in the test-retest of a slightly adjusted Deltatrac metabolic monitor. Thirteen volunteers (mean age 45 years; range 31-57 years) participated in the test-retest of Sensormedics 2900. In the first test, the subjects walked for 10 min in order to get a steady state both at an individual comfortable speed and at a preset speed. The retest was done with the same design and within 2 weeks. Nobody experienced any discomfort during the tests. The repeatability of measuring energy expenditure and RQ was acceptable for both methods and the methods were sensitive in revealing differences in energy expenditure during different walking speeds. The RQ were, however, too low when using the Deltatrac monitor, probably as a result of low air flow. We therefore conclude that only the method using Sensormedics 2900 may be used for the evaluation of energy expenditure during walking on a treadmill.
