Today’s podcast features sports performance coaches Sheldon Dunlap and Jeff Howser.

Sheldon Dunlap is currently serving as a Strength & Conditioning Specialist with MARSOC (Marine Special Operations Command). Previously, he has worked at the collegiate level coaching a wide variety of sports at UC Davis and Duke University.

Jeff Howser is a speed and performance coach with strong roots in track and field.  He spent 20 seasons as Duke’s speed and conditioning coach and has trained a variety of team sports and high-level track and field athletes.  Jeff was a world bronze medalist in the 110m high hurdles and a multi-time ACC champion.

When you look at all of the possible training variations out there today in strength and athletic performance, you realize that a great majority of our modern training has been done in some way, shape, or form, many decades ago.  One method out there that is more recent in nature is partial range, oscillatory repetition methods with barbells for the sake of improving athletic speed and power.

Sheldon appeared way back on podcast #131 speaking on his integration of oscillating reps, into the Triphasic system pioneered by Cal Dietz.  Sheldon originally learned the oscillating method from Jeff Howser (who also learned it from Cal’s influence).

On the show today, Sheldon and Jeff will be speaking extensively about the nuances of oscillatory strength training for athletics.  We’ll be covering repetition style, percentage of 1RM to utilize, integration into the rest of the program, seasonal aspects, tendon concepts, and much more.

Sheldon Dunlap and Jeff Howser Quotes
“The main thing for me is controlling the speed and distance of the oscillation and controlling the speed of the oscillation.  When I did it the oscillation distances were 6-9 inches, depending on the weight and how deep you were.  it’s not a controlled descent, you can take a lighter weight and make it a heavier weight by giving people time under t...
