True or False: Older Men Have a Much Harder Time Building Strength, Building Muscle Border"> The notion that you can't get stronger if you'repast the 60-year mark is flawed.
Nevertheless, in general, the study appears to suggest that young men are more likely to literally "grow stronger", while older men tend to draw on improvement in the mind-muscle connection, when it comes to lifting higher weights.
The common understanding that you'll have a significantly harder time to actually increase your total muscle mass and not "just" your strength, on the other hand, appears to be accurate. The signficant local increase in vastus lateralis CSA (Figure 2) does yet indicate that it's not impossible to grow even at the age of 65+ years (keep in mind, though, the subjects were previously more or less untrained!).
