Article: The quiet superpower of movement: economy as the anchor of efficient energy use

Let’s start with a simple image. You’re out for a jog. You and a friend are cruising along at the same pace, but you notice your friend looks unfazed while you’re suddenly breathing a bit heavy. Same distance, same speed—but a different energy bill. What’s going on? The answer often lies in economy: how efficiently your body uses energy to produce movement.

What exactly is economy in this world of muscles, joints, and pulses? In biomechanics, economy (or, more plainly, “economy of movement”) is about energy cost. Put simply: for a given amount of work, how much energy does your body expend? The better your economy, the less oxygen you burn and the less fatigue you feel on the clock. That matters whether you’re chasing a PB in a race or just trying to stay active without gnawing fatigue after every session.

Breaking down the four options helps anchor the idea. For a quick mental quiz, imagine you’re choosing the feature that best predicts how efficiently you perform.

• Increased stroke volume: This is about the heart’s pumping power. A bigger stroke volume means more blood can be sent out with each beat, improving oxygen delivery. It’s fantastic for endurance in a broad sense, but it doesn’t automatically tell you that you’re burning less energy for the same movement. It’s a cardiovascular upgrade that supports performance, not the direct measure of energy cost during movement.

• Improved proprioception: Your body’s sense of where it is in space, how your joints are aligned, and how you’re moving. This can improve balance and coordination, reducing wasted motions. It helps with accuracy and control, but on its own it isn’t the core indicator of energy efficiency during activity.

• Improved economy: This is the gold standard for energy cost. When people speak about economy, they mean that at the same pace or work level, they use less oxygen and energy. It’s the direct signal you’re moving more efficiently and fatiguing less over time.

• Increased heart rate: A higher heart rate during activity usually signals higher exertion or a response to activity, not a direct measure that you’re using energy more efficiently. It can rise for many reasons, including heat or stress, and isn’t a standalone marker of economy.

So, which one truly signals a more efficient energy cost? Improved economy. It’s the one that ties directly to how much energy your body needs to do the same amount of work. If you think of energy as your budget, economy is how you stretch that budget further with less waste.

Why does economy matter beyond the gym or the track? Because efficiency translates into endurance. When your body uses energy more cleanly, you can sustain a given pace longer before fatigue catches up. Athletes love it, but it matters just as much for anyone who wants to feel steadier during daily activities—climbing stairs, walking the dog, or piloting a long day at work. If you’re chasing personal bests or simply aiming to stay consistent week after week, better economy often shows up as smoother performance, less fatigue, and a more sensible energy balance.

So how does improved economy actually come about? It isn’t one magic trick; it’s a constellation of adaptations, many of them working in concert.

Technique and neuromuscular efficiency

A lot of energy cost comes down to mechanics. Small changes in posture, the way your foot strikes the ground, or how you time your steps can shave off wasted effort. Think about cadence—the number of steps you take per minute. A cadence that matches your leg length, balance, and strength can reduce braking forces and keep you from “stuttering” through strides. When your nervous system coordinates movement more efficiently, your muscles don’t have to work as hard to produce the same effect.

Strength and conditioning

Strong glutes, a solid core, and well-prepared calves don’t just add power; they help your joints move with less friction. When the body’s major movers are well-tuned, you’re more likely to glide through a motion with less compensatory effort. That translates into lower oxygen use for the same speed. It’s not about blasting muscles to lift more; it’s about aligning tissue capacity with the demands of movement so energy can flow more smoothly.

Proprioception and balance work

Balance drills, single-leg work, and proprioceptive challenges teach your nervous system to recruit the right muscles at the right time. Fewer misfires, fewer micro-adjustments, and fewer awkward shifts equal less wasted energy. It’s the quiet work that sometimes feels invisible until you notice the gains in steadiness and rhythm.

Metabolic efficiency and oxygen use

Your body’s ability to extract and use oxygen in the working muscles matters. Over time, training can tilt the balance toward more efficient lactate handling, better mitochondrial density, and improved enzymatic activity in the muscles. The upshot? For the same workload, your body sacralizes less energy on a per-meter basis. That’s improved economy in a very tangible form.

A few tangible analogies help crystallize the idea. Imagine two cars cruising at the same speed on a highway. One car gets better mileage—less fuel per mile—than the other. That’s economy. Now swap cars for bodies: the athlete with better movement economy uses less oxygen per kilometer, so they can go farther with the same effort. It’s not about pushing harder; it’s about moving smarter.

Practical tips to nudge your economy upward (without turning workouts into a chore)

• Fine-tune form: Start with a simple assessment of your movement pattern. A coach or even a video capture can spotlight issues—overstriding, excessive vertical bounce, or knee collapse—that waste energy. Small tweaks can have outsized effects.

• Cadence first, then stride length: If you’re slowing down due to fatigue, experiment with your step rate. A comfortable, quicker cadence often pairs with shorter ground contact time, reducing braking forces.

• Strength training that mirrors movement demands: Prioritize hip extensors, hamstrings, and the core. Think routines like step-ups, hip thrusts, planks, and controlled nordic hamstring slides. The goal isn’t to look bulky but to provide a reliable scaffold for efficient movement.

• Balance and proprioception work: Include single-leg squats, balance boards, or simple eyes-closed stance holds. They may feel like play, but they tune your nervous system to recruit the right muscles at the right moments.

• Progressive, not punishing, load: Build your training gradually. Economy improves as your body adapts, not in a single breakthrough session. A steady rhythm beats a sprint that leaves you spent.

• Warm up to prime efficiency: A smart warm-up that includes light cardio, dynamic mobility, and short tempo strides can prepare your muscles and nerves for efficient work. When you start at a well-tuned notch, you’re less likely to waste energy in the first minutes.

• Footwear and surface choices matter, but don’t overthink them: Shoes that are too soft or too rigid can alter gait in ways that cost energy. Matching shoe feel to your biomechanics and choosing consistent surfaces can help maintain an efficient rhythm, but the core gains come from technique and strength.

• Listen to your body: If you notice you’re tiring early or your form feels off, reassess. Recovery and good nutrition support energy efficiency by keeping the body ready to move efficiently, not tired and clumsy.

A quick reality check: bigger HR and bigger stroke volume aren’t the endgame by themselves

You’ll hear a lot of talk about heart rate and how hard the heart pumps during activity. It’s a powerful signal, but it isn’t the sole indicator of economy. A high heart rate at a given pace can simply mean you’re pushing harder, not that you’re moving more efficiently. Conversely, a strong stroke volume helps your oxygen supply, which is critical for endurance—but if the movement pattern wastes energy, the benefit of a bigger pump won’t be fully realized. The goal is harmony: a heart that delivers reliable oxygen and a nervous system that coordinates movement with precision.

What this means in real life

If you’re chasing longer sessions with less fatigue, or you’re trying to keep up with life’s everyday demands without feeling drained, economy is your quiet ally. It’s the kind of progress that doesn’t shout; you notice it in the smoothness of a run, the steadiness during a long walk, or the lack of a sharp energy drop after a workout. It’s the difference between feeling like you’re grinding through a workout and feeling like you’re gliding through it.

A few practical takeaways to carry forward

• Economy is all about energy cost. When you move more efficiently, you burn less energy for the same task.

• Improved economy emerges from the right blend of technique, strength, balance, and neuromuscular coordination.

• Focus on small, sustainable changes rather than big, rapid shifts. Consistency beats intensity when it comes to economy.

• Use the body’s feedback loop: if you feel wasted energy or unusual fatigue, check your form, your load, and your recovery.

The bigger picture

Movement is a complex symphony of heart, lungs, muscles, nerves, and even our brains. Improved economy is not a single trick; it’s the culmination of training that tunes every part of that system to work together. When you experience better economy, you’ll notice it in longer exercise bouts, more comfortable workouts, and a greater sense that you can push a little further without paying a heavy energy price.

If you’re curious to explore this further, start with a simple experiment. Pick a comfortable pace and run or ride for 10 minutes, then repeat at the same pace after a light warm-up. Track your effort with a simple RPE (rate of perceived exertion) scale and, if possible, measure your oxygen cost with basic equipment or apps that estimate effort. Notice how small changes in form or cadence shift how you feel and how long you can sustain the pace. That’s economy in action, doing its quiet work beneath the surface.

The energy budget of movement is a fascinating topic because it touches so many aspects of training and daily life. It’s less about chasing a single metric and more about cultivating a body that can move with less waste and more grace. If you keep that focus, you’ll likely find that your performance improves and your days feel a little less taxed after activity. And isn’t that the core of staying active with confidence and enjoyment?

Takeaway recap

• The best indicator of a more efficient energy cost during physical activity is improved economy.

• Other options—like increased stroke volume, improved proprioception, or higher heart rate—support performance in different ways but don’t directly signal energy efficiency in the same way.

• Improving economy comes from a mix of technique, strength, proprioception, and metabolic efficiency, all working together.

• Practical steps you can take include refining technique, boosting targeted strength, balancing proprioception work, and training with a steady, progressive approach.

With a little patience and consistent, thoughtful practice, you’ll likely notice that your workouts feel smoother and your energy lasts longer. That steady, practical progress—built on a foundation of better economy—can reframe how you approach movement, turning everyday activity into a more effortless, enjoyable part of life.
