how to Understanding your 'BODY COMPOSITION'

  Hi fitness trainer   

BODY COMPOSITION

Body composition refers to the proportions of fat, bone, water, and muscle in human bodies. Understanding your body composition can provide insight into your overall health and fitness level. Here's a breakdown of the key components included in body composition:

 1.  Types of Fat Storage 

Essential Fat (Viscaral fat): Necessary for normal bodily functions, including protecting internal organs, storing energy, and regulating hormones. It's found in small amounts in the bone marrow, organs, central nervous system, and muscles.

Storage Fat: Accumulates in adipose tissue, which can be subcutaneous (under the skin) or visceral (around internal organs).  

         ✔️  Ideal levels of body fat %

Definition: The ratio of adipose tissue to lean body mass. Ideal body composition for males is ≤15% fat, and for females ≤20% fat

• Muscle vs. Fat–Which Weighs More?

Two kilograms of fat looks compared to two kilograms of muscle.

• Can Fat convert to Muscle ?

• Fat cell and Muscle cell

• Characteristics of adipose tissue

• Muscle and Fat -Distinct Entities

          

•               Muscle is denser than fat

                                    

•                Hypertrophy , Hyperplasia , Atrophy  introduction

       2.  Lean Body Mass (LBM):

·         Muscle Mass: Includes all the muscles in your body, which are essential for movement, strength, and metabolic processes.

·         Bone Mass: The weight of your bones, which are important for structure and support.

·         Body Water: Accounts for the amount of water in yourbody, which is crucial for various physiological functions.

·         Organs and Other Tissues:  Includes the weight of your organs and other tissues, such as skin.

3.  Bone Density:

Refers to the strength and density of your bones, which is important for overall skeletal health.

Methods to Measure Body Composition

1.  Bioelectrical Impedance Analysis (BIA):

Measures the resistance of body tissues to the flow of a small electrical signal to estimate body fat percentage, lean body mass, and body water.

 2.  Dual-Energy X-Ray Absorptiometry (DEXA):

Uses X-ray beams to measure bone mineral density, fat mass, and lean body mass with high accuracy.

3.  Hydrostatic Weighing:

Involves submerging a person in water to measure body density and calculate body composition.

4.  Air Displacement Plethysmography (Bod Pod):

Measures body volume and density using air displacement to determine body composition.

5.  Skinfold Measurements:

Uses calipers to measure the thickness of skinfolds at various body sites to estimate body fat percentage.

6.  Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) Scans:

Provide detailed images of body tissues, allowing for precise measurement of body composition.
