ABSTRACT
The purpose of this study was to investigate the effects of various cold immersion durations on maximal grip strength and the subsequent recovery of grip strength. Sixteen healthy men between 20 and 42 years of age participated in this study. Maximal isometric grip strength was measured before, immediately after, and 5, 10, and 15 minutes after cold immersion. Subjects submerged their dominant elbow, forearm, and hand in a cold water whirlpool at 10 degrees C for 5, 10, 15, or 20 minutes. There was a significant decrease in isometric grip strength when the forearm was immersed in 10 degrees C water for durations between 5 and 20 minutes and no recovery of this strength loss for a period of 15 minutes following removal from the cold immersion (p = 0.0001). These findings suggest that clinicians should be aware of the alterations in isometric muscle strength that result from utilizing the temperature and time frames of cold application used in this study.
