Short answer: Mostly no.
Longer answer: Are you injured often? If not, then again, no.
Much longer answer: The body defaults to the most efficient cadence for your fitness. It feels inefficient to increase cadence because it IS inefficient. It's not just your muscles, the CNS has to fire the muscles faster so to run at a higher cadence, you need do cadence drills to train the Central Nervous System to fire faster without tiring out.
Short, fast hill reps will help with faster turnover. Here are two drills that I do.
3 sets of 3x200m. Over the last 50-70m of the 200m rep, I will swing my arms faster, but not speed up. This results in a choppy stride. I typically run with a partner so I can be sure that I'm not speeding up. On the last rep of each set, I increase cadence AND speed up. This last rep is tiring so you might need to add a couple of minutes to the rest between sets.
The second drill is to run with a metronome app set at slightly higher than your current cadence. Since your normal cadence for 800m is 170 that's a good cadence to use as a starting point. Set your metronome for a cadence for 175. Don't try to run the entire rep at that cadence, just run for 5-10 seconds and revert to normal cadence until you recover.
After three weeks or so, you'll find it easier to hold that 175 cadence. You can either increase the cadence to 180 or increase the distance (time) run at 175. REMEMBER, these are drills do don't be concerned about whether you are faster or slower. BTW, 175 is just an arbitrary number on a few beats higher. You might try 174, 178, 180, etc.
After some experimentation, you'll find a "sweet spot". Going faster cadence than that will tire you out quickly.
Even if you determine, after experimentation, that your ideal 800m cadence is exactly what you're running now, practicing these faster turnover drills should improve your kick at the end of a race.
Anyway, that's what helps me. Best of luck!
