Axman, Tyler, Esfeld, Shane, Jackson, Corey, Moore, Ashley, and Daniel Quillin. 2013. The Effects of Cryotherapy and Hot-pack Treatments on Quadriceps Femoris Strength Measured by an Isokinetic Machine . -- In Proceedings: 9th Annual Symposium: Graduate Research and Scholarly Projects.

The purpose of this investigation was to test the assumption that the application of heat will produce a greater increase in muscle strength as compared to the application of ice. Thirty-five male and female university students were randomly distributed into three groups: cryotherapy (ice) group (IG), heat group (HG), or control group (CG). Each participant performed a three minute warm-up on a standard Airdyne stationary cycle. Pre-test measures for fiverepetition maximum knee extension strength were obtained for each participant by use of an isokinetic dynamometer. After intervention, post-test measures were obtained using the same parameters. Although no significant difference was observed between groups, trends tend to show an increase in knee extension strength following the application of a heat modality.
