RESTING METABOLIC RATE ASSESSMENTπ€π§
An (RMR) assessment measures how many calories your body burns at rest to maintain basic physiological functions like breathing and cellular repair. Itβs typically measured in calories per day π€
How RMR is Measuredπͺ
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 (VOβ) and carbon dioxide production (VCOβ) to calculate your calorie burn ππ»
How can an RMR assessment help YOUR Sporting Performance?? π₯
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 ποΈββοΈ
4. If youβre aiming to gain muscle or reduce fat, knowing your RMR helps you avoid under- or overeating π₯³
5. Helps maintain energy availabilityβcritical for endurance athletes or those in weight-class sports ππ»ββοΈπ₯
6. Prevent Energy Deficiency. Athletes often underfuel, leading to Relative Energy Deficiency in Sport (RED-S)βa syndrome that affects performance, bone health, menstrual function, and immunity. Knowing your RMR ensures your energy intake doesnβt drop too low βοΈ
7. Improve Training Adaptations. Fueling in line with your metabolic needs ensures that your body can adapt to training loads effectivelyβimproving strength, endurance, and recovery π
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 adaptationβespecially during long-term dieting or intense training blocks β±οΈ
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.
