All Exercise Is Aerobic: How Real-Time Muscle Oxygen Monitoring Revolutionizes Exercise Science Education

How Moxy Monitor revolutionizes exercise physiology education by revealing that all exercise uses oxygen

The Challenge with Teaching Traditional Exercise Physiology Bioenergetics

Picture this: You're teaching exercise physiology, explaining the three energy systems to a room full of eager students. You describe how each energy system is dominant during different durations of all-out exercise, from the phosphocreatine system to glycolysis to aerobic metabolism. Then you pose the question: "So during a sprint, my muscles aren't using oxygen at all?"

Crickets, OR a bold student might be brave enough to say, “NO”!

If you've taught exercise science, you're probably acutely aware of this misconception. And if we’re honest, the traditional way we teach energy systems—with neat diagrams showing distinct activation of "anaerobic" and "aerobic" phases—can sometimes create more confusion than clarity.

Here's the problem: Students perceive that exercise is either aerobic OR anaerobic, when the reality is that all energetic systems are always activated AND exercise is fundamentally connected to oxygen.

Why the "Anaerobic vs. Aerobic" Teaching Method Fails Students

For decades, exercise physiology textbooks have presented energy systems working in sequence. Students learn that:

• The phosphocreatine system works without oxygen
• Glycolysis doesn’t require oxygen, so its "anaerobic" 
• Only longer, steady-state exercise uses oxygen

While technically accurate in terms of the reactions required in each step, this teaching approach misses the bigger picture. Students graduate thinking that a 100-meter sprint has nothing to do with oxygen, when in reality, oxygen is the foundation of ALL energy production in the human body.

How Real-Time Muscle Oxygen Monitoring Changes Students Perceptions

This is where Moxy Monitor can help. Instead of asking students to imagine what's happening inside their muscles, we can show them—in real time.

When students place a Moxy on a working muscle and perform different types of exercise, something remarkable happens. Whether they're doing:

• A 10-second all-out sprint (supposedly "pure" phosphocreatine and anaerobic)
• 30-second high-intensity intervals (supposedly "glycolytic" and anaerobic)
• Steady-state cycling (aerobic)

The Moxy reveals an immediate drop in muscle oxygen saturation (SmO2) in ALL cases, the extent of this drop will depend directly on the force requirement BUT nonetheless, a drop in oxygen occurs with all muscle contraction!

This isn't equipment malfunction—it's physiology in action.

When Students See Oxygen Working in Real Time: The "Aha!" Moment

When students see their SmO2 plummet within seconds of starting ANY exercise, the lightbulb should go off. They realize that:

• All energy systems are always active—they don't work in sequence, but synergistically
• Oxygen demand increases immediately with any exercise, and is higher with more intensity
• The "anaerobic" systems still depend on oxygen for substrate replenishment
• Post-exercise oxygen consumption (EPOC) reveals the oxygen debt created by "anaerobic" work

Suddenly, that sprint isn't just about stored phosphocreatine. Students can see how their muscles are desperately trying to deliver oxygen to meet the immediate energy demand, and how elevated oxygen consumption continues long after the exercise stops.

Why Traditional Exercise Physiology Labs Miss the Mark

Traditional exercise physiology labs rely on indirect calorimetry—measuring oxygen consumption at the mouth with expensive metabolic carts. While valuable, this approach has limitations:

• Delayed response: VO2 takes about a minute to reflect increased muscle oxygen demand
• Global measurement: Doesn't show what's happening in specific working muscles
• Expensive equipment: Often limits hands-on student experience
• Misleading timeline: The slow VO2 response reinforces the "anaerobic first, aerobic later" misconception

How Moxy Monitor Transforms Exercise Science Education

Moxy Monitor changes this by providing:

• Immediate feedback: SmO2 responds within seconds
• Muscle-specific data: Shows exactly what's happening where the work is being done
• Accessible technology: Multiple students can use devices simultaneously
• Real-time learning: Students see their physiology respond as it happens

Practical Applications for Exercise Physiology Classrooms

Universities across the country are already integrating Moxy into their exercise physiology curricula. Students design experiments to stress different energy systems, then watch as their muscle oxygen data reveals the integrated nature of metabolism.

A typical lab might include:

• 5-second sprints to emphasize the phosphocreatine system
• 30-60 second intervals targeting glycolytic pathways
• Steady-state exercise emphasizing oxidative metabolism

In every case, students observe immediate oxygen utilization and elevated post-exercise oxygen consumption—concrete evidence that all exercise is fundamentally about oxygen.

Building Better Exercise Scientists for the Future

This isn't just about correcting a misconception. When students truly understand that oxygen underpins all energy production, they develop a more sophisticated understanding of:

• Training adaptation mechanisms
• Recovery physiology
• Metabolic flexibility
• Performance limitations

They stop thinking in rigid categories and start appreciating the elegant integration of human metabolism.

Preparing Students for Modern Exercise Science Careers

As exercise science continues to evolve, professionals need to understand real-time physiological monitoring. Moxy technology is already being used by:

• Elite athletes for training optimization
• Researchers studying muscle metabolism
• Clinicians assessing muscle function
• Coaches monitoring training loads

By exposing students to this technology in the classroom, we're not just teaching better physiology—we're preparing them for careers at the cutting edge of exercise science.

The Bottom Line: Show, Don't Tell

The next time you want to demonstrate that even sprinting uses oxygen, you don't have to rely on diagrams and explanations. You can use a Moxy Monitor and show them exactly what's happening in their muscles.
