Comment Fonctionne le Calcul
Calculs de composition corporelle utilisent formules scientifiques établies. Méthode IMC estime graisse corporelle à partir d'IMC, âge et genre. Méthode Navy utilise mesures de circonférence pour calcul plus précis de graisse corporelle. Formule Boer estime masse corporelle maigre directement à partir du poids, taille, âge et genre. Chaque méthode a différents niveaux de précision - méthode Navy est généralement plus précise pour population générale.
Scénarios d'Exemple
Un homme athlétique de 25 ans pesant 80kg avec 180cm de taille et 80cm de tour de taille a environ 68.5kg de masse corporelle maigre (14.4% de graisse corporelle) utilisant méthode Navy, tombant dans catégorie 'Athlétique'
Une femme fitness de 30 ans pesant 65kg avec 165cm de taille a environ 46.8kg de masse corporelle maigre (27.9% de graisse corporelle) utilisant formule Boer, indiquant bon niveau de fitness
Un homme moyen de 35 ans pesant 75kg avec 175cm de taille a environ 60.2kg de masse corporelle maigre (19.7% de graisse corporelle) utilisant méthode IMC, dans plage normale saine

Frequently Asked Questions
What's the difference between lean body mass and body fat?
Lean body mass includes everything in your body except fat - muscles, bones, organs, water, and connective tissue. Body fat is the fat stored in your body. Lean body mass is metabolically active and crucial for health and performance, while excess body fat can impact health.
Which calculation method is most accurate?
Accuracy varies: BMI method is least accurate (estimates only), Navy method is moderately accurate for general population, Boer formula is good for estimating lean mass. For highest accuracy, professional methods like DEXA scans, hydrostatic weighing, or skinfold measurements by trained professionals are recommended.
What are healthy body fat percentages?
Healthy ranges vary by gender and age: Men typically 10-20% (athletic), women 18-28% (athletic). Essential fat is 2-5% for men, 10-13% for women. Body fat below essential levels can impair health. Above 25% for men and 32% for women increases health risks.
How does body composition change with age?
Body fat naturally increases with age while lean mass decreases. This is called sarcopenia (muscle loss). Regular resistance training and adequate protein intake can help maintain lean mass. Metabolism also slows with age, affecting body composition maintenance.
Can I build muscle and lose fat at the same time?
Body recomposition (building muscle while losing fat) is possible for beginners and those returning to training. It becomes harder with experience. Focus on progressive overload, adequate protein (1.6-2.2g/kg), calorie deficit/surplus, and consistent training. Track lean body mass changes over time.
Why is body composition more important than weight?
Body composition reveals what's inside your weight - muscle vs fat ratio. Two people can weigh the same but have very different health profiles. Higher muscle mass improves metabolism, strength, and health outcomes. Body composition changes should be the focus over scale weight alone.
How often should I measure body composition?
Measure every 4-6 weeks during training programs to track progress without excessive frequency. Daily weight fluctuations can mask true composition changes. Use the same method and conditions each time for consistent measurements. Focus on trends rather than single measurements.
