Difference in functional and ventilatory parameters of the maximal bicycle ergometry test before and after PUFA or placebo intervention during an 8 week rehabilitation programme
| PUFA† (n = 37)Mean (SD) | Placebo† (n = 38)Mean (SD) | PUFA versus placebo‡Mean (95% CI) | p value | |
|---|---|---|---|---|
| FFM, fat-free mass; V˙e, peak ventilation; V˙co2, peak carbon dioxide production; V˙o2, peak oxygen consumption; RER, respiratory exchange ratio. | ||||
| †Variables before and after intervention were compared within groups by the paired Student’s t test, *p<0.05. | ||||
| ‡The change in outcome of the variables after 8 weeks of intervention were compared between groups by linear regression with baseline value of the parameter, intervention with PUFA, and intervention with drink supplements as predictors (p<0.05). Values represent adjusted means with 95% confidence intervals. | ||||
