498: Aaron Uthoff on Backwards Running and Linear Sprint Speed
Today’s guest is Aaron Uthoff. Aaron Uthoff, PhD, is a sport scientist and coach whose work sits right at the intersection of biomechanics, motor learning, and sprint performance. His research digs into acceleration, force application, and some less conventional forms of locomotion, including backward sprinting, with the goal of connecting solid science to what actually works on the field, track, or in rehab.
Backward running shows up all the time in warm-ups and general prep. Most of the time, though, it’s thrown in casually, without much thought about what it might actually be doing for speed, coordination, or tissue loading.
In this episode, Aaron walks through his path into performance science, which is anything but linear. From skiing in Montana and playing desert sports, to football and track, to a stretch training horses in Australia, his journey eventually led him to research mentors in Arizona, Scotland, and New Zealand. That broad background shows up clearly in how he thinks about movement.
One of the big takeaways from our conversation is Aaron’s overview of research showing that structured backward running programs can improve forward acceleration and even jumping ability. We also get into how backward running can be used as a screening and coordination tool, and where it fits into rehabilitation, including what’s happening at the joints, how muscles are working, and how to progress it without forcing things.
We finish by digging into wearable resistance, including asymmetrical loading, and why this emerging tool may have more upside for speed and movement development than most people realize.

Actionable Takeaways
6:40 – Posture sets the ceiling for movement quality
Good movement often starts with orientation, not technique cues.
Aaron emphasizes looking at ribcage position, pelvis orientation, and head placement before trying to fix limb mechanics.
Clean posture gives athletes access to better options without forcing patterns.
13:25 – Breathing influences coordination and output
Breathing is not just recovery, it shapes how force is expressed.
Use simple breathing resets to help athletes feel better alignment and rhythm.
Watch how breathing patterns change movement quality before adding more coaching input.
20:45 – Tempo reveals how athletes organize movement
Tempo exposes whether an athlete can control positions under time pressure.
Slowing or slightly speeding tasks can uncover compensations without verbal instruction.
Use tempo to teach rhythm instead of constantly correcting mechanics.
30:10 – Constraints beat constant verbal cueing
Aaron highlights using task constraints to guide learning instead of over explaining.
Change distances, targets, or starting positions to let athletes self organize.
Good constraints reduce the need for constant coaching intervention.
40:55 – Sprint mechanics improve through shapes, not forcing positions
Trying to force textbook sprint positions often backfires.
Focus on global shapes and direction of force instead of individual joint angles.
Let athletes discover better sprint mechanics through drills that preserve intent.
51:20 – Environment is a powerful teacher
Surface, space, and task design matter more than many cues.
Use varied environments to expand an athlete’s movement vocabulary.
Small changes in environment can create big changes in coordination.
1:01:30 – Strength training should support movement, not override it
Strength work should expand options, not lock athletes into rigid patterns.
Choose lifts and loading schemes that preserve posture and rhythm.
If strength training degrades movement quality, reassess the intent.
1:12:15 – Coaching is about learning what to ignore
Not every flaw needs fixing.
Aaron emphasizes knowing which details matter in the moment and which do not.
Better coaches simplify their lens rather than add more rules.
Quotes from Aaron Uthoff
“Posture is often the biggest limiter of movement quality, not strength or mobility.”
“Breathing changes how the nervous system organizes movement.”
“Tempo tells you more about coordination than maximal output ever will.”
“If you have to keep cueing it, the task probably needs to change.”
“Good sprinting comes from better shapes, not chasing perfect positions.”
“The environment can do more coaching than your words.”
“Strength should give athletes more options, not fewer.”
“Part of coaching maturity is learning what not to coach.”

496: Dustin Oranchuk on Isometrics, Force Production and Elastic Performance
Today’s guest is Dustin Oranchuk, Ph.D. Dustin is a sport scientist focused on sprinting biomechanics, speed development, and force production. Known for blending research with practical coaching insight, his work explores how isometrics, elasticity, and coordination shape high-performance sprinting and athletic movement.
Isometric training is one of the “original” forms of strength training, and in the modern day has become one of the most popular areas of discussion and training methodology. Although the practice has exploded, it often lacks an understanding of physiology of adaptation with various methods.
In this episode, Dustin explores the evolving world of isometric training, including the origins of isometrics. We discuss differences between pushing and holding contractions, tendon and neural adaptations, and modern applications in performance, rehab, and longevity. The conversation also dives into eccentric quasi-isometrics (EQIs), motivation and measurement challenges, and how coaches can intelligently integrate isometrics alongside plyometrics and traditional strength work.

Actionable Takeaways
5:38 Evolution of Isometric Training
Overcoming isometrics originated as a way to target sticking points with high force.
Early isometric systems emphasized position specific strength over movement.
Modern usage has expanded beyond barbell sports into rehab and longevity.
8:38 Modern Applications of Isometrics
Isometrics are now widely used to “own positions” across joint angles.
Longer duration holds are frequently used for tissue health and rehab.
Training intent has shifted from peak strength toward durability and resilience.
9:52 Neural vs. Morphological Adaptations
Short range, position specific isometrics bias neural intent and coordination.
Long muscle length isometrics bias hypertrophy and tendon adaptation.
Choose isometric type based on whether the goal is performance transfer or tissue change.
15:45 The Importance of Long Holds
Tendons require relatively high intensity to meaningfully adapt.
Long holds help reveal side to side asymmetries and control deficits.
Extended holds build tolerance and confidence in vulnerable joint positions.
19:42 Combining Isometrics and Plyometrics
Pairing isometrics and plyometrics can produce modest additive benefits.
Combining methods may reduce fatigue compared to doing each alone.
The interaction may enhance effort quality rather than purely physiological output.
39:22 Exploring Eccentric Quasi Isometrics
EQIs combine a maximal hold followed by forced eccentric lengthening.
They accumulate large time under tension and eccentric impulse.
EQIs are powerful but mentally taxing and difficult to sustain long term.
47:10 Periodization and Isometric Training
Use longer, lower intensity holds earlier in the offseason.
Progress toward shorter, higher intensity, position specific isometrics near competition.
Post game isometrics can support recovery without additional joint stress.
1:05:48 Future Research Directions
Measurement technology has driven the resurgence of isometrics.
Push versus hold distinctions are becoming a key research focus.
Future work aims to clarify muscle and tendon behavior during isometric intent.
1:13:00 Closing Thoughts and Reflections
Consistency with foundational exercises drives long term progress.
Isometrics are tools, not replacements for dynamic training.
Coaches should match the method to the goal, not the trend.
Quotes from Dustin Oranchuk
“Tendons tend to need a certain threshold of intensity to get meaningful adaptations.”
“The maximal amount of force you can push is almost always more than what you can hold.”
“Isometrics let you own positions rather than just pass through them.”
“Long holds are a great diagnostic tool for finding asymmetries.”
“EQIs are effective, but they are very hard to push hard and regularly.”
“Use the best tool for the job rather than trying to blend everything together.”
“Consistency beats constantly reinventing your training approach.”
“Isometrics compress joint motion so other systems can recover and adapt.”
“Intent matters just as much as the muscle action itself.”
“You do not need complexity to get strong adaptations over time.”
