Key result
Surgically induced weight loss significantly increased effort test duration from 13.8 to 21 minutes at 1 year (p<0.001).
Why the study?
Does bariatric surgery improve exercise capacity in patients with morbid obesity?

Does bariatric surgery improve exercise capacity in patients with morbid obesity?
Absolute Event Rate: 21% vs 13.8%
p-value: p=<0.001
Surgically induced weight loss in morbidly obese patients significantly improves exercise capacity by reducing energy expenditure for external work.

Bariatric surgery may increase exercise capacity in morbid obesity; leaves open whether RCTs confirm functional benefits.
Serés et al. (2006) conducted a cohort in Morbid obesity (n=31). Surgically induced weight loss (bariatric surgery) vs. Before surgery (baseline) was evaluated on Effort test duration (minutes) (p=<0.001). Surgically induced weight loss significantly increased effort test duration from 13.8 to 21 minutes at 1 year (p<0.001).
