Strength training has lots of benefits -- for people of all ages -- and ideally it should be a component of a balanced overall fitness program. However, for the average person (following the average gym-based workout routine) it won't have a clinically significant affect on their Resting Metabolic Rate.

It’s not uncommon to hear or read claims that, “if you gain one pound of muscle you will burn about 50 extra calories per day.” If only it were that easy...
In fact, the resting metabolic rate of skeletal muscle is frequently confused with the resting metabolic rate of the lean body mass as a whole. Lean body mass however includes all our organs (liver, brain, heart, and kidneys) which burn 15 to 33 times more calories by weight than skeletal muscle.

The majority of clients I’ve worked with over the years had matter-of-factly accepted the notion that they had a “low metabolism,” possibly secondary to yo-yo dieting.
Several comprehensive reviews of the literature (including one by a National Institutes of Health expert panel), however, have concluded that the negative metabolic and body composition side-effects frequently attributed to yo-yo dieting are not supported by careful review of the data. The conclusions: yo-yo dieting does not have a lasting negative effect on resting energy expenditure (REE), or muscle tissue/lean body mass (LBM), and does not make future attempts at weight loss more difficult (at least from a physiological standpoint).
