Change of Body Composition and Functional Status Following Short-term Pre-habilitation Among Morbidly Obese Patients Before Bariatric Surgery

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| anthropometry (waist circumference in cm) | change in waist circumference at 2 weeks | baseline and after 2 weeks | 
| body composition (weight in kg) | change in weight at 2 weeks. It will be measured by using BIA TANITA | baseline and after 2 weeks | 
| body composition (muscle mass in kg) | change in muscle mass at 2 weeks. It will be measured by using BIA TANITA | baseline and after 2 weeks | 
| body composition (fat free mass in kg) | change in fat free mass at 2 weeks. It will be measured by using BIA TANITA | baseline and after 2 weeks | 
| body composition (fat mass in kg) | change in fat mass at 2 weeks. It will be measured by using BIA TANITA | baseline and after 2 weeks | 
| body composition (fat percentage in percentage) | change in fat percentage at 2 weeks. It will be measured by using BIA TANITA | baseline and after 2 weeks | 
| functional status (hand-grips strength in kg) | change in hand-grips strength at 2 weeks. Hand-grip strength will be measured by using Jammar Dynamometer | baseline and after 2 weeks |
