1. ABSTRACT
The purpose of this investigation was to examine the effects of sprint/plyometric training with the
MERIDIAN Elyte Performance training shoe on various performance parameters. Seventeen healthy
men were randomly assigned to either a Nike Air Zoom Seismic athletic shoe-training group (AS) or a
MERIDIAN Elyte shoe training group (SS). Both groups participated in an eight- (8) week training
program consisting of weight training and sprint/plyometric training. Anthropometry, muscular
strength, speed, power, and rate of force development assessments were performed pre and post
testing. Both groups demonstrated similar increases in 1 RM squat and bench press, power output,
and rate of force development during jumping. Both groups demonstrated similar improved 40-yard
dash times but the SS group showed greater improvement in 60-yard dash times (4 vs. 2%
respectively). The SS group significantly increased vertical jump height whereas only a trend for
improvement (p = 0.08) was observed in the AS group. Rate of force development of the plantar flexor
muscles in the dorsiflexed position improved to a greater extent in the SS group. Compared to two-
(2) previous studies, this newly designed model of strength shoe showed a lower incidence of pain
and injury. In conclusion, the results of the present study indicate that the MERIDIAN Elyte model
shoe may have ergonomic effect on performance when used during eight- (8) weeks of
sprint/plyometric training.
