SPEED TRAINING SCIENCE: Why Most Methods Fail (And What Actually Works)
Most athletes train hard but don’t get faster. This article explains the science behind speed training, including muscle contraction, fast twitch fibers, and why traditional methods often fail to improve speed.
Why Getting Bigger Can Actually Make You Slower (The Science Explained)
Many athletes believe getting bigger will make them faster—but that’s not always true. Learn how hypertrophy affects muscle function, contraction speed, and why size alone doesn’t translate into real performance.
Spine Rotator Muscles for Running Speed: How Rotation Connects Your Entire System
Spine rotators don’t create speed—they connect your system. Learn how rotation transfers force and improves coordination for faster running.
What Actually Creates Force in Running? (And Why Most Athletes Get It Wrong)
Force is one of the most misunderstood aspects of running. Many athletes think strength alone creates speed, but force depends on how your system applies and transfers energy. Learn what actually creates force in running and how to improve it.
Why Faster Turnover Doesn’t Always Make You Faster (The Stride Rate Myth)
Many athletes believe faster turnover automatically creates more speed. AQ explains why stride rate is often a reflection of sprint-system function and why identifying the real limitation may matter more than simply trying to move your legs faster.
The Real Cause of Overstriding (And Why It’s Not What You Think)
Many athletes try to fix overstriding by changing where the foot lands. AQ explains why overstriding may be the visible outcome of deeper contributor limitations involving the pushing leg, swing leg, arms, torso, and strength balance.
What Influences Ground Contact Time? (And Why Quick Feet Aren’t The Answer)
Most athletes assume shorter ground contact time creates faster running. AQ explains why contact time may often be an outcome of contributor relationships already influencing the next step before the foot reaches the ground.
Does Foot Strike Matter? (Yes—But Probably Not As Much As You Think)
Does foot strike matter for running speed? AQ explains why foot strike deserves attention, but often isn’t the biggest factor limiting sprint performance.
What Influences Ground Mechanics? (And Why The Foot Isn’t Always The Source)
Ground mechanics describe how the foot interacts with the ground during running. AQ explains why the foot may be where ground mechanics become visible, while the sprint system may be what influences them.
What Is Strength Balance? (And Why It Governs Running Speed)
Most athletes focus on producing more force to run faster. AQ explains strength balance, force-output balance, and why running speed depends on how much balance the pushing side and swing side can achieve together.
Why Running Form Mistakes Keep Coming Back
Many athletes focus on visible running form mistakes such as overstriding, upper-body tension, and awkward arm action. AQ explains why some of these movement problems may be compensations that emerged after something deeper began falling behind.
Stride Length vs Stride Frequency: What Really Makes You Faster?
Many athletes think they must choose between stride length and stride frequency to run faster. AQ explains why both are often outcomes of speed-producing improvements happening underneath rather than the true source of speed itself.
Push Phase vs Swing Phase: The Missing Half of Running Speed
Most athletes think speed comes primarily from the push phase. AQ explains why the swing phase is not recovery, how it contributes during every stride, and why faster running depends on both phases working together.
Arm Swing Mechanics in Sprinting: Why Your Arms Matter More Than You Think
Most athletes view arm swing as a balancing mechanism. AQ explains why the arms do far more than simply move opposite each other, how they contribute to the pushing side during sprinting, and why arm action may play a much larger role in sprint speed than many athletes realize.
