Domande Frequenti
How is adjusted body weight calculated?
ABW = IBW + 0.4 × (Actual Weight − IBW). First calculate Ideal Body Weight using the Devine formula (men: 50 + 2.3 × inches above 5 feet; women: 45.5 + 2.3 × inches above 5 feet). Then add 40% of the difference between actual and ideal weight.
When should I use adjusted body weight instead of actual weight?
ABW is used clinically when actual body weight exceeds ideal body weight by >30%, primarily for drug dosing, nutritional calculations, and anesthesia. For everyday health and fitness calculations in non-obese individuals, actual body weight is appropriate.
How does weight affect running performance?
Each kg of excess fat increases the energy cost of running by approximately 1%. A runner losing 5 kg of fat while maintaining muscle mass would see approximately 5% improvement in running economy — roughly 2–4 minutes faster in a marathon. This relationship is one of the strongest and most practical performance predictors in recreational running.
What is ideal body weight for a runner?
There is no universal ideal body weight for runners. The optimal is individual and depends on genetics, muscle mass, and training history. Elite marathon runners are typically lean (BMI 18–21), but this is the result of training, not a target to pursue through restriction. Focus on body composition (body fat %) rather than absolute weight.
How often should I recalculate?
Recalculate when your weight changes by 5+ kg, when your activity level changes significantly, or every 3–6 months to account for age-related metabolic changes. For athletes, recalculate training-related values after any significant change in fitness, body composition, or training load.
Are these calculations accurate for everyone?
All calculations use validated scientific formulas but are estimates based on population averages. Individual variation means any estimate could be off by 10–20% for a specific person. Use the results as starting points and adjust based on real-world outcomes over several weeks of monitoring.
How do I track progress with this calculator?
Take measurements under consistent conditions (same time of day, same hydration state, same scales/devices) and record results with the date. Re-measure every 4–8 weeks during active training or diet phases. Look for consistent directional trends over 4+ weeks rather than reacting to individual fluctuations, which are largely caused by measurement variation and normal biological variation.
What other metrics should I track alongside this?
For comprehensive health monitoring, no single metric tells the whole story. Combine body composition metrics (weight, body fat %, waist circumference) with performance metrics (running pace at a standard heart rate, 5K time, 1RM strength) and wellbeing metrics (sleep quality, resting heart rate, HRV). The most meaningful progress often shows in performance and wellbeing metrics before it shows on the scale.
