The Longitudinal Effects of Resisted Sprint Training Using Weighted Sleds vs. Weighted Vests

KENNETH P. CLARK, DAVID J. STEARNE, CORY T. WALTS,AND ANTHONY D. MILLER

Purpose: To determine thelongitudinal effects of weighted sled (WS) and weighted vest(WV) sprint training on maximum velocity sprint performanceand kinematics. Average velocity across the distance interval of 18.3 to 54.9 m were used.

Conclusions: The results indicate that WS and WV training had no beneficial effect compared with unresisted training (UR). In fact, for the loads used by WS and WV inthis study, UR training may actually be superior for improving sprint performance in the 18.3- to 54.9-m interval.

IN PLAIN ENGLISH: Overloading a skill by using resistance is clearly not (and has never been although many still are too stubborn to believe it) a sensible means of training. Do not violate the principles of specificity!
