The effect of exercise on body fat and nutrient intake in men with quadriplegia
The benefits of exercise were examined in men with quadriplegia. Eleven athletes and eleven non-athletes completed the study. Three-day food intake records and anthropometric measurements were analyzed for body fat and dietary intake compliance with the Recommended Dietary Allowances [RDA] for selected vitamins and minerals, the American Heart Association [AHA] guidelines for fat and cholesterol intake, and the National Cancer Institute [NCI] guidelines for fiber. The t test for independent groups and the Pearson product moment correlation were used to detect group differences and correlation among the variables. The groups were matched by age, level of injury, and duration of injury. Group differences were statistically significant for body weight (P<0.05), kilograms of fat free mass (P<0.01), waist:hip ratio (P<0.05), energy intake (P<0.05), and carbohydrate intake (P<0.05). Differences between the groups are not statistically different for body fat, percent body fat or diet compliance as had been expected. Mean dietary intake for both groups was near 75% of the RDA for nutrients tested. Both groups consumed >150% of the RDA for Vitamin C, and 50% of the RDA for zinc. Total fat, saturated fat and cholesterol intakes for both groups were near the AHA guidelines. Fiber intake was less than 50% of the NCI guidelines for both groups. Findings indicate that athletes have decreased body weight while consuming increased calories. Mean hours of exercise per week of 6.18 in the athlete group and 0.27 hours in the non-athlete group did not have the expected effect on the variables.
