DLCO is one of the most useful numbers in lung testing — but it’s also one of the most misunderstood. Many patients and even clinicians notice DLCO values “bounce” between tests. Is that real change or just measurement noise?. Recent evidence shows that inter-session differences can exceed traditional thresholds for a meaningful change. Absolute shifts beyond 3.5 mL/min/mm Hg, 15
If you have ever searched for “anaerobic threshold by age,” you have seen tidy tables that promise a quick answer. They look convenient, but they are not accurate for real training decisions. Threshold is not a single number determined by your birth year. It is a physiological tipping point that shifts with training status, genetics, modality, and even the day’s
Winter is the right time to upgrade your aerobic engine with structured intervals that target VO2 Max while respecting recovery and injury risk. With snow, darkness, and fewer races, you can control variables, stack consistent sessions, and use lab data to set precise intensity without guessing. The result is faster progress, fewer setbacks, and clear feedback from session to session.
You can make big endurance gains this year by pairing laboratory-measured zones with a simple weekly split: 80 percent easy and 20 percent hard. With VO₂ and threshold testing, your ventilatory thresholds (VT1 and VT2) give you precise anchors for easy, moderate, and hard training so you stop guessing and start adapting. This guide shows you how to translate your
If you want your 2026 season to be predictable and progressive, it should start with a true baseline. A structured fitness assessment removes guesswork from your training zones, fueling strategy, and body-composition goals. At Metatec, a baseline fitness test combines VO₂ max, ventilatory and anaerobic thresholds, maximum heart rate, resting metabolic rate, and DEXA body composition — then translates that
The holidays can push nutrition and training off course with travel, parties, and irregular schedules. You do not need guesswork or rigid rules — you need a precise daily calorie target based on your metabolism. Resting Metabolic Rate (RMR) testing provides the number you need to set calories and macros with confidence, enjoy events without losing progress, and return to
If you want a clean slate in January, you need a clean baseline now. Body composition sets the foundation for realistic training and nutrition targets—and the tool you use determines how precise your plan can be. Consumer bioimpedance smart scales are quick and accessible, but they estimate your fat and muscle using electrical current and population equations. DEXA scans, the
Training by heart rate only works when your maximum heart rate (max HR) is accurate. The common shortcut 220 minus age is simple but often misses by 10–20 bpm in either direction. That error ripples through your zones, pacing, and recovery. Here’s why the formula fails, how to measure your real max HR, and safe ways to self-check if you’re
You train to get faster, go longer, and race smarter. The challenge is knowing exactly where aerobic efficiency ends and anaerobic cost begins. Your thresholds set the ceiling for sustainable pace, the heart rate zones youshould live in during base work, and how you should fuel during long sessions or race day. This guide shows how common field methods stack
Understanding your Resting Metabolic Rate (RMR) provides the foundation for evidence-based nutrition and training decisions that optimize performance and body composition. Rather than relying on generic calorie recommendations or one-size-fits-all diet approaches, RMR testing delivers precise data about your individual energy requirements. This scientific approach enables targeted interventions that align with your specific metabolic profile, supporting sustainable results and long-term
