RESTING METABOLIC RATE ASSESSMENT๐ค๐ง
An (RMR) assessment measures how many calories your body burns at rest to maintain basic physiological functions like breathing and cellular repair. Itโs typically measured in calories per day ๐ค
How RMR is Measured๐ช
RMR is often assessed via indirect calorimetry, a non-invasive method where you breathe into a mask or canopy hood for 15-30 mins. It measures oxygen consumption (VOโ) and carbon dioxide production (VCOโ) to calculate your calorie burn ๐๐ป
How can an RMR assessment help YOUR Sporting Performance?? ๐ฅ
1. Optimize Nutrition for Performance and recovery.
Knowing your RMR value helps allows you to set accurate daily calorie needs, including training and recovery demands.
2. Tailor macronutrient intake (carbs, protein, fats) to support energy, muscle repair, and endurance.
3. Supports lean mass goals ๐๏ธโโ๏ธ
4. If youโre aiming to gain muscle or reduce fat, knowing your RMR helps you avoid under- or overeating ๐ฅณ
5. Helps maintain energy availabilityโcritical for endurance athletes or those in weight-class sports ๐๐ปโโ๏ธ๐ฅ
6. Prevent Energy Deficiency. Athletes often underfuel, leading to Relative Energy Deficiency in Sport (RED-S)โa syndrome that affects performance, bone health, menstrual function, and immunity. Knowing your RMR ensures your energy intake doesnโt drop too low โ๏ธ
7. Improve Training Adaptations. Fueling in line with your metabolic needs ensures that your body can adapt to training loads effectivelyโimproving strength, endurance, and recovery ๐
8. Avoids chronic fatigue or overtraining syndrome.
9. Track Changes Over Time. RMR can change with training volume, age, body composition, and dieting history.
Monitoring RMR over time helps identify metabolic adaptationโespecially during long-term dieting or intense training blocks โฑ๏ธ
Who Benefits Most from RMR Testing?
Endurance athletes (runners, cyclists, triathletes)
Strength athletes (powerlifters, bodybuilders)
Hybrid athlete (Hyrox, CrossFit)
Combat or weight-class athletes (boxers, wrestlers)
Female athletes with irregular energy intake or menstrual issues.
