Brief summary

Observational study is conducted in patient under short term pre-habilitation before bariatric surgery.

Detailed description

Observational study is conducted in patient under short term pre-habilitation before bariatric surgery. Data on anthropometry (waist circumference), body compositions (weight, muscle mass, fat free mass, fat mass, fat percentage and basal metabolic rate (BMR)), and functional status (handgrips strength) are collected.

Interventions

OTHERprehabilitation

very low calories diet (800-1000kcal/day) with moderate intensive aerobic exercise (1 hour per section; 3 sections per day)
