Abstract

The purpose of this dissertation was to determine the effects of peristaltic pulse dynamic compression administered via NormaTec recovery system provides measurable kinetic, kinematic, or perceptual benefits following a weightlifting training session. During 2 testing sessions separated by 1 week, 6 weightlifters performed dynamic mid thigh pulls on a force plate with potentiometers at loads equal to 50%, 60%, 70%, 80%, 90%, 100%, 110%, and 120% of 1 RM clean before and after a weightlifting training session consisting of 5 sets of 5 repetitions of clean pulls from the floor with 90% of 1 RM clean and treatment with the NormaTec recovery system or a sham treatment. Following a cross over design the weightlifters served as their own control receiving NomaTec treatment during 1 testing session and sham treatment during 1 testing session. Pre- and postdynamic mid thigh pulls were analyzed for peak force, force at 50 ms, force at 90 ms, force at 250 ms, impulse at 50 ms, impulse at 90 ms, impulse at 250 ms, rate of force development, peak velocity, peak power, and peak displacement. A 2x2 (treatment, time) repeated measures ANOVA showed no statistical differences in the interaction of treatment and time with the exception of impulse at 250 ms at the 70% load. The minimal effects of NormaTec on recovery from a weightlifting training session demonstrated in this study suggest that NormaTec recovery system does not provide substantial benefits following clean pulls from the floor. However, it is possible that NormaTec may be more effective following a greater level of eccentric damage or a test of strength endurance.
