This investigation determined the benefits of the Hamstrong device after downhill running. Sixteen healthy college-aged males volunteered to participate in the repeated measures experimental study. They were assigned to either run with or without the device. They ran for forty minutes at 75% of their calculated VO2 Max speed. The effects of the device or absence of the device were examined as well as the PROM and isometric hamstring strength. The subjects had to repeat the protocol (minus the running) at three different time periods following the exercise. Repeated measures ANOVA did not reveal a significant (F=0.119, p=0.705) effect for the left leg PROM, nor a significant (F=0.016, p=0.977) effect for the right leg PROM. Repeated measures ANOVA did not reveal a significant effect (F=0.578, p=0.128) for the right leg at 90 degrees of extension during isometric strength testing, but there was a significant effect (F=1.027, p=0.032) for the left leg at the same angle. Repeated measures ANOVA did not reveal a significant effect (F=0.797, p=0.063) for the right leg at 135 degrees of extension during isometric strength testing, nor a significant effect (F=0.227, p=0.467) for the left leg at the same angle. There were no other changes regarding the effects of the device regarding myoglobin concentration.
