What is your fuel source being used for your workout?
PNOE Metabolism Testing provides a precise way to determine heart rate zones based on an athlete’s metabolic response, utilizing VO2 and VCO2 data to establish individualized thresholds.
The five heart rate zones align with different energy systems and training adaptations.
Heart Rate Zones, Energy Systems, Benefits, and Training Methods:
Zone 1 (Active Recovery / Aerobic Base)
- Energy System: Primarily oxidative (aerobic metabolism)
- Intensity: 50-60% of max HR (Low intensity)
- Fuel Source: Mostly fat oxidation with some carbohydrate usage
- Benefits:
- Enhances recovery by increasing blood flow
- Improves mitochondrial efficiency and fat oxidation
- Strengthens the parasympathetic nervous system (supports recovery and stress adaptation)
- Builds a strong aerobic base, essential for endurance
- Training Method:
- Easy-paced workouts (walking, light cycling, conversational pace jogging)
- Active recovery sessions post-hard workouts
Zone 2 (Aerobic Efficiency / Fat Max)
- Energy System: Oxidative (aerobic metabolism) with peak fat oxidation

- Fuel Source: Maximal fat oxidation with minimal carbohydrate usage
- Benefits:
- Optimizes fat metabolism, increasing metabolic efficiency
- Improves mitochondrial density and function
- Builds endurance capacity and lowers lactate accumulation
- Supports metabolic flexibility (ability to use fat as fuel)
- Training Method:
- Long, steady-state aerobic workouts (cycling, jogging, Zone 2-specific endurance sessions)
- Fasted cardio for metabolic adaptation
Zone 3 (Aerobic Threshold / Tempo Zone)
- Energy System: Oxidative (aerobic) with increasing anaerobic (glycolytic) contribution
- Intensity: 70-80% of max HR (Moderate-to-high intensity)
- Fuel Source: Mix of fat and carbohydrates, with carbs becoming dominant
- Benefits:
- Increases lactate clearance efficiency (buffering capacity)
- Improves cardiovascular efficiency (stroke volume and cardiac output)
- Enhances ability to sustain moderate-hard efforts
- Bridges the gap between endurance and higher-intensity work
- Training Method:
- Tempo runs, steady-state efforts at or just below lactate threshold
- Progressive endurance workouts
Zone 4 (Lactate Threshold / High Intensity)
- Energy System: Primarily glycolytic (anaerobic metabolism)
- Intensity: 80-90% of max HR (High intensity)
- Fuel Source: Mostly carbohydrate metabolism, minimal fat oxidation
- Benefits:
- Increases lactate threshold, allowing athletes to sustain higher intensities longer
- Improves muscle buffering capacity and anaerobic endurance
- Develops power and speed endurance
- Training Method:
- Interval training, threshold runs (e.g., 4×10 min at threshold with short recovery)
- Functional threshold power (FTP) cycling intervals
Zone 5 (VO2 Max / Anaerobic Capacity)
- Energy System: Phosphagen (ATP-PC) & Glycolytic (Anaerobic)
- Intensity: 90-100% of max HR (Very high intensity)
- Fuel Source: Carbohydrates (glycogen) with high lactate production

Each zone plays a role in optimizing performance, metabolic efficiency, and endurance. With PNOE metabolic testing, these zones are precisely identified based on an individual’s unique physiology rather than generalized formulas, allowing for more effective training personalization.
Shifting Fuel Sources as we increase the Intensity:
The shift from fat oxidation (aerobic metabolism) to carbohydrate metabolism (anaerobic metabolism) as exercise intensity increases is driven by several physiological and biochemical mechanisms.
Here’s how the body transitions from primarily using fat via mitochondrial oxidation (low-intensity) to carbohydrate metabolism (higher-intensity):
1. AMPK Activation and Fat Oxidation at Low Intensities (Aerobic Metabolism)
- AMPK (AMP-activated protein kinase) is a key regulator of energy balance. During low-intensity exercise (Zones 1-2), AMPK is activated due to the increased AMP/ATP ratio, signaling low energy availability.
- AMPK stimulates fat oxidation by:
- Increasing transport of fatty acids into mitochondria (activating CPT-1, carnitine palmitoyltransferase-1).
- Upregulating mitochondrial biogenesis to enhance oxidative capacity.
- Inhibiting acetyl-CoA carboxylase (ACC), reducing malonyl-CoA, which otherwise inhibits CPT-1.
- In this state, the body relies on oxidative phosphorylation in the mitochondria, which efficiently generates ATP from fat stores.
2. Glycolytic Shift at Moderate Intensities (Lactate Threshold)
- As exercise intensity increases (Zone 3-4), ATP demand rises, and fat metabolism alone becomes insufficient to supply energy quickly.
- Carbohydrate metabolism becomes more dominant due to:
- Increased glycolysis: Faster ATP production from glucose breakdown.
- Reduced fatty acid oxidation: Rising levels of acetyl-CoA and citrate inhibit CPT-1, slowing fat transport into mitochondria.
- Greater lactate production: The glycolytic flux increases, leading to more pyruvate conversion to lactate when mitochondrial oxidation reaches capacity.
- Muscle glycogen becomes the primary fuel as the mitochondria reach their oxidative limit, forcing the body to rely more on anaerobic glycolysis.
3. Anaerobic Energy Pathways at High Intensities (Carbohydrate Dominance)
- In high-intensity zones (Zone 4-5), ATP demand is extremely high, requiring faster energy sources:
- Phosphagen System (ATP-PCr): Immediate ATP supply for short bursts of max effort (e.g., sprints).
- Anaerobic Glycolysis: Rapid glucose breakdown with lactate production to sustain high-intensity work.
- Fat oxidation is nearly shut down because:
- Glycolysis provides ATP at a much higher rate than beta-oxidation.
- Rising lactate and hydrogen ion accumulation inhibit mitochondrial function.
- Oxygen availability is lower, prioritizing anaerobic metabolism.
Key Takeaways:
-
Low Intensity (Fat Oxidation & AMPK Activation)
- High mitochondrial reliance
- Efficient but slow ATP production
- AMPK promotes fat oxidation
-
Moderate Intensity (Glycolytic Shift)
- Increased carbohydrate use
- Fat oxidation declines due to glycolytic inhibition
- Lactate production begins to rise
-
High Intensity (Anaerobic Glycolysis & ATP-PCr System)
- Mitochondrial oxidation maxes out
- Fast ATP production via glycolysis
- Lactate accumulation leads to fatigue
This shift allows the body to efficiently meet energy demands at different intensities, balancing endurance and power output.
Here’s a chart summarizing the shift from fat oxidation (AMPK-driven) to carbohydrate metabolism as exercise intensity increases:
| Exercise Intensity | Energy System | Primary Fuel | Mechanism of Action | Key Physiological Changes |
|---|---|---|---|---|
| Low Intensity (Zones 1-2) | Aerobic (Oxidative Phosphorylation) | Fat (via mitochondrial oxidation) | – AMPK activation increases fat oxidation – CPT-1 transports fatty acids into mitochondria – Mitochondrial ATP production is efficient but slow |
– High mitochondrial reliance – Minimal lactate production – Low carbohydrate use |
| Moderate Intensity (Zone 3 – Lactate Threshold) | Aerobic + Increasing Glycolysis | Fat + Carbohydrates (transitioning to carbs) | – Rising ATP demand shifts metabolism to include glycolysis – Increased pyruvate conversion to lactate – Fat oxidation begins to decline due to mitochondrial saturation |
– Increased glycolysis – Higher carbohydrate reliance – Increased lactate production |
| High Intensity (Zone 4 – Above Lactate Threshold) | Anaerobic Glycolysis | Primarily Carbohydrates (muscle glycogen) | – ATP demand outpaces mitochondrial oxidation – Lactate accumulates as glycolysis increases – Fat oxidation is suppressed |
– Glycolytic ATP production dominates – High lactate levels – Reduced mitochondrial efficiency |
| Max Effort (Zone 5 – VO2 Max / Sprint) | Phosphagen (ATP-PCr) + Anaerobic Glycolysis | ATP-PCr + Carbohydrates | – ATP generated rapidly via phosphagen system – Anaerobic glycolysis provides additional ATP – Complete suppression of fat oxidation |
– Maximal lactate accumulation – Oxygen deficit increases – Fast fatigue onset |
How to Do Sprint Training Properly with Adequate Recovery (Zone 1) & Why It’s Important
Sprint training is a powerful tool for improving metabolic efficiency, fat oxidation, and mitochondrial biogenesis. However, balancing high-intensity work with sufficient recovery (Zone 1 training) is crucial to avoid overtraining, central fatigue, and metabolic dysfunction.
Why Proper Recovery (Zone 1) Matters in Sprint Training
1. Prevents Excessive Lactate Accumulation & Fatigue
- Sprinting generates high lactate levels, which must be cleared to maintain performance.
- Zone 1 (very low intensity) allows lactate clearance via the Cori Cycle.
- Incomplete recovery leads to accumulated fatigue, reduced power output, and longer recovery times.
2. Supports Mitochondrial Function & Fat Oxidation
- High-intensity efforts rely on glycolysis (glucose metabolism), which can suppress fat oxidation.
- Active recovery in Zone 1 encourages a shift back to fat metabolism, enhancing metabolic flexibility.
3. Maximizes Sprint Performance & Anaerobic Capacity
- Without proper recovery, each sprint rep decreases in power output.
- Full recovery ensures ATP-PC (adenosine triphosphate-phosphocreatine) system replenishment, allowing max effort in each sprint.
Mechanism of Action: Sprint Training & Recovery Balance
-
Sprint Effort (High-Intensity Anaerobic Work)
- Energy Systems Used:
- First 10 sec: ATP-PC system (stored ATP & creatine phosphate)
- 10-30 sec: Glycolytic system (glucose metabolism) → lactate buildup
- Key Response:
- High power output
- Increased glycolysis, lactate accumulation
- Fast-twitch fiber activation (Type IIa & IIx)
- Energy Systems Used:
-
Recovery Phase (Zone 1: Active Recovery)
- Energy Systems Used:
- Oxidative system (mitochondria) gradually clears lactate
- Fat oxidation is restored as heart rate drops
- Key Response:
- Clears lactate through the Cori Cycle (lactate → glucose in liver)
- Replenishes ATP-PC stores (~3 min for full recovery)
- Promotes fat oxidation & metabolic flexibility
- Energy Systems Used:
How to Structure Sprint Training with Proper Recovery
| Sprint Protocol | Intensity | Work:Rest Ratio | Recovery Zone & Time |
|---|---|---|---|
| Short Sprints (10-15 sec) | 90-100% Max Effort | 1:5 to 1:10 | 60-90 sec Zone 1 active recovery (HR < 65% max) |
| Max Effort Sprints (20-30 sec) | 100% Max Effort | 1:8+ | 3-5 min Zone 1 easy cycling or walking |
| Sprint Intervals (30-60 sec) | 85-95% Max Effort | 1:4 to 1:6 | 4-6 min slow jogging or walking |
| Tabata (8x 20 sec sprints) | 90-95% Max Effort | 1:2 (short recovery) | Full recovery after the set: 5-10 min in Zone 1 |
Additional Tips for Optimizing Sprint Training & Recovery
✅ Perform sprints on fresh legs (avoid excessive fatigue)
✅ Prioritize full recovery (avoid incomplete rest between sprints)
✅ Incorporate low-intensity sessions (Zone 1 & Zone 2) on non-sprint days
✅ Fuel properly (adequate carbohydrates pre-sprint, protein for recovery)
✅ Use HRV tracking to monitor readiness and avoid overtraining
What, How, and Why to Create New Mitochondria?

How Aging Females Should Fuel, Train, and Perform Differently Than Aging Men
Aging women experience hormonal shifts that significantly impact metabolism, muscle mass, recovery, and fuel utilization. While both men and women benefit from strength, aerobic, and metabolic training, women must adjust fueling, training intensity, and recovery strategies to account for declining estrogen and progesterone, which influence muscle preservation, fat oxidation, and insulin sensitivity.
Key Differences in Aging Female vs. Male Physiology
| Factor | Aging Females | Aging Males |
|---|---|---|
| Hormonal Changes | ↓ Estrogen & Progesterone → affects metabolism, muscle recovery, & fat oxidation | Gradual ↓ in Testosterone → affects muscle mass, but more stable metabolism |
| Metabolism | Lower metabolic rate, higher fat storage (esp. visceral) | More muscle mass → higher resting metabolic rate |
| Muscle Mass | ↓ Anabolic response, increased risk of sarcopenia | Slower muscle loss, better retention of lean mass |
| Fat Oxidation & Insulin Sensitivity | ↓ Fat oxidation, higher insulin resistance post-menopause | Better insulin sensitivity, slower metabolic decline |
| Recovery & Stress Tolerance | Higher cortisol response, slower recovery | Less cortisol sensitivity, better stress adaptation |
How Aging Women Should Adjust Their Fueling, Training & Performance Strategies

- How?
✅ Train 3-4x per week with heavy resistance (5-8 reps, 3-5 sets)
✅ Focus on compound movements (squats, deadlifts, presses) for bone density & lean mass retention
✅ Add power exercises (jumps, sprints) to combat loss of fast-twitch muscle fibers
2. Prioritize Protein for Muscle Maintenance & Recovery
- Why? Older women have anabolic resistance and need more protein per meal to stimulate muscle protein synthesis.
- How?
✅ Reproductive years: 25-30g protein per meal
✅ Perimenopause & postmenopause: 40-50g protein per meal to counteract muscle breakdown
✅ Leucine-rich sources (grass-fed meat, whey, eggs, collagen)
3. Adjust Carbohydrate Intake for Insulin Sensitivity
- Why? Estrogen declines → increased insulin resistance → higher risk of abdominal fat gain
- How?
✅ Prioritize carbs around workouts (30-50g pre/post-workout for strength days)
✅ Low-carb on rest days (emphasize fiber, healthy fats, and protein)
✅ Avoid fasted high-intensity exercise (risk of increased cortisol & muscle breakdown)
4. Balance Sprint & Endurance Workouts for Metabolic Flexibility
- Why? Women rely more on fat oxidation than men but need intensity to maintain metabolic health
- How?
✅ Zone 2 (aerobic base work, 2-3x per week) → expands mitochondria, improves fat metabolism
✅ Sprints & HIIT (1-2x per week) → maintains insulin sensitivity & fast-twitch muscle
✅ Strength before cardio (preserve muscle mass & avoid excess cortisol response)
5. Manage Stress & Recovery Proactively
- Why? Postmenopausal women experience higher cortisol responses, leading to fat storage & slower recovery
- How?
✅ HRV Tracking to adjust training load & avoid overtraining
✅ Prioritize sleep (7-9 hours) & optimize circadian rhythm
✅ Use heat & cold therapy to improve stress adaptation & mitochondrial health
Summary: Female-Specific Goals vs. Aging Men
| Focus | Aging Women (Postmenopause) | Aging Men |
|---|---|---|
| Primary Goal | Maintain muscle mass, metabolic flexibility, & insulin sensitivity | Maintain testosterone & muscle mass |
| Best Training Approach | Heavy lifting, sprinting, Zone 2 aerobic base | Strength, endurance, metabolic work |
| Carb Strategy | Cycling carbs (higher around workouts, lower on rest days) | Higher tolerance for carbs |
| Fat Utilization | Requires training to improve fat oxidation | Better baseline fat oxidation |
| Recovery Focus | More sleep, lower cortisol, active recovery | More emphasis on mobility & muscle maintenance |
Bottom Line: How Women Should Train & Fuel Differently Than Men
✅ Lift heavy (strength training 3-4x/week)
✅ Increase protein (40-50g per meal post-menopause)
✅ Adjust carbs (strategic intake for insulin sensitivity)
✅ Sprint & Zone 2 balance (boost mitochondria & fat oxidation)
✅ Prioritize recovery (stress management, HRV tracking, sleep)
