Wait a minute…is all this about Super Slow a la Wayne Westcott, Richard Winett and Ken Hutchins?
For those who aren’t familiar with Super Slow, the first study was done in 1993 and repeated in 1999 by Wayne Westcott, fitness research director at the South Shore YMCA in Quincy, Massachusetts. The study was seriously flawed (even the authors admitted it was not well controlled).
An opposing, better controlled, study by D. K. Liow and W. G. Hopkins (Journal Medicine and Science in Sports and Exercise, 1998) studied thirty-nine experienced male and female kayakers were matched by sex and sprint time and randomly assigned to a slow weight training, explosive weight training, or control (normal training, without weights) group. They trained twice a week for six weeks using unspecified sports-specific weight training exercises.
“The kayakers were tested before and after for time in the 15 meter sprint.
The kayaking study probably produced the results that most exercise physiologists would have predicted. After all, the most time-honored principle in sports science is the specificity principle: specific adaptation to imposed demand (SAID). Dr. Pat O’Shea, who made the case for lifting rapidly in our Lift Slow or Lift Fast article, highlights the importance of specificity in the second edition of his book Quantum Strength. He calls the SAID principle the “guiding force” of strength training. “It explains that physiological, neurological, and psychological adaptation will occur in direct response to the imposed training demands. If, however, these demands are not specific to the performance demands of your sport, no functional adaptation will take place.””
The researchers described the implications: "Slow weight training exercises train one to respond best when moving slow. Fast weight training exercises train athletes to respond best when moving fast. However, both forms of training improved performance better than no weight-training."
Disadvantages: 1) SuperSlow does NOT train the muscles specifically for sprinting or fast movements needed in cycling, dynos in climbing, basketball jumps and the like. It seems to target primarily slow twitch, rather than fast twitch muscles-- more endurance training, rather than. power/speed; 2) This type of training seems to be more effective for people new to lifting (lighter weights), although the article indicated that some athletes use this technique.
