Research Paper Title

Muscle mass gain observed in patients with short bowel syndrome subjected to resistance training.

Background

Few studies are available about the evaluation of resistance training in patients with protein energy
malnutrition.

Methods

To assess the effects of resistance training on the recovery of nutritional status of patients with short bowel syndrome, with a small bowel remnant of less than 100 cm, 9 patients of both sexes with protein-energy malnutrition after extensive resection of the small bowel were submitted to resistance training of progressive intensity consisting of concentric and eccentric work exercises for the upper limbs, trunk, and lower limbs, with the individuality and limitations of each patients being respected.

Food consumption was monitored by 24-hour food recall performed during the initial phase of the study, before and 7 and 14 weeks after physical training, and by a dietary record for a period of 3 days of oral feeding. The nutrients administered by the enteral and parenteral route were recorded.

Results

A significant increase in total arm area (P ≤ .01) and fat-free mass (P ≤ .01) was observed as determined by computed tomography. An increase in total energy ingestion and carbohydrate consumption (P ≤ .01) was also observed. In addition, the activity of the enzyme carnosinase was increased after resistance training (P ≤ .01).

Conclusions

The present results show that resistance training in patients with short bowel syndrome and protein-energy malnutrition can be considered to be a part of the nonmedicamentous treatment of these patients, leading to better nutrient use and to a gain of lean mass.
