Abstract
We examined correlations between echo intensity and muscle strength and endurance. Rectus femoris echo intensity, maximal voluntary contraction (MVC) force and time to task failure during a 50% MVC task were determined for 12 younger (mean age = 25 y) and 13 older (mean age = 74 y) men. Bivariate correlations between echo intensity and normalized MVC force were similar for younger and older men, but was only statistically significant for the latter (younger r = â0.559, p = 0.059; older r = â0.580, p = 0.038). When all patients were combined, the correlation was significant (r = â0.733, p < 0.001). Significant correlations were not observed for time to task failure (younger r = â0.382, p = 0.221; older r = â0.347, p = 0.246; all patients r = â0.229, p = 0.270). Rectus femoris echo intensity is associated with muscle strength, but not endurance, in younger and older men.
